Definitions
- the invention relates to a method for applying liquids, in particular thermoplastics, to a substrate, the substance being melted, heated and applied to a carrier material by means of a nozzle or a doctor blade through a perforated cylinder.
- Substrates which are coated with highly viscous materials are known in the medical field. From certain points of view, it makes sense that these coatings do not have closed surfaces but are applied in a punctiform manner, which, for example, allows the skin under bandages not to macerate due to the possibility of sweat and other exudates from the skin.
- An adequate process to achieve this punctiform coating is rotary screen printing.
- a nozzle through which the fluid to be coated is introduced from outside into the sieve space and is pressed through the sieve holes in the direction of the substrate to be coated.
- the sieve is lifted off the substrate according to the transport speed of the substrate (rotation speed of the sieve drum). Due to the adhesion and the internal cohesion of the fluid, the limited supply of hotmelt adhesive in the holes is subtracted from the base of the calottes, which is already adhering to the carrier, or is conveyed by the existing pressure on the carrier. After this transport has ended, depending on the rheology of the fluid, the more or less strongly curved surface of the spherical cap forms over the predetermined base area.
- the ratio of the height to the base of the spherical cap depends on the ratio of the hole diameter to the wall thickness of the screen drum and the physical properties (flow behavior, surface tension and wetting angle on the carrier material) of the fluid.
- the materials must be compatible with the skin, generally permeable to air and / or water vapor, as well as easy to mold and conform. Because of these requirements, the thinnest or softest carrier is often preferred. Sufficient strength and, if necessary, limited elasticity are also required for handling and use of the carrier materials. Furthermore, the carrier material should have sufficient strength and low elasticity even after it has been soaked.
- Adhesives particularly preferably self-adhesives, are preferably used for the coating of carrier materials with a later medical, cosmetic or technical use. These preferably belong to the material classes of the solutions, the dispersions, the prepolymers and the thermoplastic polymers.
- Thermoplastic hotmelt adhesives based on natural and synthetic rubbers and other synthetic polymers such as, for example, acrylates, methacrylates, polyurethanes, polyolefins, polyvinyl derivatives, polyesters or silicones with appropriate additives, such as adhesive resins, plasticizers, stabilizers and other auxiliaries, are advantageously used where necessary.
- Their softening point should be higher than 50 ° C, the application temperature is usually at least 90 ° C, preferably between 100 ° C and 180 ° C, or 180 ° C and 220 ° C for silicones.
- the process therefore requires that the hotmelt adhesive be brought to an appropriate temperature in order to liquefy it so that it can pass through the sieve holes.
- the hot melt adhesive is usually brought to the appropriate temperature in the feed system and in the nozzle.
- an attempt is made to set the highest possible temperature, since this lowers the viscosity of the adhesive and a higher production speed can be achieved.
- there are strict limits to this process because if the temperature is too high, the hotmelts are subject to a chemical decomposition process in a short time, which is unacceptable, especially with medical coatings that come into contact with the skin.
- heating elements that are designed as radiation sources are arranged in or around the sieve (EP 0 288 541 A1). Heating with hot air is also described (CH 648 497 A5).
- these types of heating have the disadvantage that not only is energy applied to the screen, but also to the environment and the substrate to be coated due to the scatter and the permeability of the screen to radiation and air flow.
- Another disadvantage of this device is that the screen heats up much more in the areas in which it is not in contact with the substance, the substrate to be coated and the nozzle than in the areas in which there is such contact the heat is dissipated. Temperature differences of 40 to 60 ° C are the rule here. This results in a zonal mechanical weakening of the screen materials that mostly occurs in the peripheral areas due to embrittlement due to overheating. The result is that the screen breaks in a destructive manner, particularly at higher production speeds.
- a disadvantage of the heating of the entire circumference is on the one hand the chemical stress on the surrounding thin adhesive film remaining on the sieve due to the intensive energy input with a large surface / volume ratio and thus a large contact area with the surrounding atmospheric oxygen, on the other hand the unnecessary radiation of part of the energy introduced to the environment.
- the object of the invention is to provide a method which is excellently suitable for applying viscous liquids to a carrier material and which avoids the disadvantages known from the prior art.
- the invention relates to a method for applying liquids, in particular thermoplastics, to a substrate, the substance being melted, heated and applied to a carrier material by means of a nozzle or a doctor blade through a perforated cylinder.
- the perforated cylinder is heated in the circular arc segment of the cylinder in which the liquid passes through the cylinder, the circular arc segment covering an angle of up to 180 °, preferably from 5 ° to 90 °, based on the center of the sieve.
- the essence of the method is thus that the screen is heated exclusively or in addition to a further heating in the circular arc segment in which the liquid passes through the screen.
- This segment covers an angle of up to 180 °, preferably from 5 ° to 90 °, based on the center of the screen.
- the heated circular arc segment can be arranged both in front of and behind the point of passage of the liquid in the direction of rotation of the sieve.
- the heated circular arc segment is preferably arranged in the direction of rotation of the perforated cylinder on both sides of the passage of the liquid, in order both to ensure heating of the screen in front of the passage point and to enable heating in the detachment zone of the point.
- the heating element lying against the direction of rotation before the passage of the liquid forms a continuously decreasing gap until full contact with the sieve in the direction of rotation. It proves advantageous if the gap continuously decreases in the direction of rotation from 3 mm to 0 mm, preferably from 0.3 mm to 0 mm.
- a nozzle designed in this way increases the temperatures of the adhesive residues present in the sieve without the sieve initially being in contact with the heating element and only makes contact when the adhesive has reached a viscosity by increasing the temperature, at which it does not contribute to the torsion of the sieve guaranteed.
- the adhesive can increasingly take on the function of a lubricating film between the screen and the heating element.
- the formation of the lubricating film is supported in an advantageous embodiment in that the surface of the heating plate that faces the sieve at least partially has an ordered or irregular structure with a roughness depth of 0.001 to 1 mm, preferably of 0.01 to 0.5 mm has, for example, a groove in the direction of rotation of the surface.
- the heating circle segment On the side lying in the direction of rotation after the passage opening of the liquid, the heating circle segment is designed as follows in order to heat the screen in the To enable the area to detach the cap:
- the distance to the sieve is constantly 0 to 3 mm, but preferably 0.01 mm to 0.2 mm.
- a heating plate can also be placed on the screen from the outside on the circle segment lying in the direction of rotation in front of the point of passage of the adhesive, which follows the curve of the screen.
- the heating plate can be heated with oil or electricity using the usual methods. This is particularly useful when high coating speeds are to be achieved.
- the design of the heating plate which is in contact with the outside proves to be advantageous if it forms a circle segment which is 5 - 10 ° smaller, preferably 6 - 7 ° smaller, relative to the circle segment within the sieve. Furthermore, it is advantageous if the heating plate is at a distance from the sieve of 0.0 mm to 3 mm, preferably 0.0 mm to 0.1 mm. Here, too, the distance can be continuously reduced in order to form the adhesive as a lubricating film.
- the heating element or the area of the nozzle that is designed as a heating element should at least partially pass seamlessly into the lateral delimitation lip of the nozzle outlet opening.
- a nozzle designed in this way enables the viscosity of the adhesive to be reduced briefly without chemical decomposition, provides a long service life for the sieve in production, since the brittleness and torsion on the edges are eliminated due to the toughness of the adhesive, and avoids thermal stress in the vicinity of the coating location , In addition, heating in the direction of rotation behind the point of passage of the adhesive can save an additional thread melter in many cases.
- radiation sources such as infrared emitters, are used as heating elements, but according to the invention act exclusively in the circular arc segment in which the liquid passes through the sieve and which has an angle of 0 ° to 180 °, preferably from 5 ° to 45 ° based on the center of the screen.
- heating elements on the nozzle or the direct integration of these into the nozzle can lead to undesired heating of the nozzle body, for example due to heat conduction effects.
- a tempering medium such as thermal oil or water, would have to dissipate this heat.
- this liquid is fed to the nozzle at a temperature which is below the desired coating temperature and is heated therein to the coating temperature by the amount of heat to be removed.
- correspondingly arranged flow channels for example a double-walled inflow pipe arranged centrally in the axial direction in the nozzle base body, in which the liquid first flows through the outer jacket closer to the heating elements and is then passed into the inner distribution pipe.
- liquids with a dynamic zero viscosity of 0.1 to 1000 Pas can advantageously be coated, preferably with a dynamic zero viscosity of 1 to 500 Pas.
- Suitable substances to be applied are all inorganic and organic compounds whose viscosity can be brought into the above range by increasing the temperature, including dispersions, emulsions, solutions and melts.
- Adhesives particularly preferably self-adhesives, are preferably used for the coating of carrier materials with a later medical, cosmetic or technical use. These preferably belong to the material classes of the solutions, the dispersions, the prepolymers and the thermoplastic polymers.
- Thermoplastic hotmelt adhesives based on natural and synthetic rubbers and other synthetic polymers such as are advantageously used examples include acrylates, methacrylates, polyurethanes, polyolefins, polyvinyl derivatives, polyesters or silicones with appropriate additives such as adhesive resins, plasticizers, stabilizers and other auxiliaries where necessary.
- Their softening point should be higher than 50 ° C, since the application temperature is usually at least 90 ° C, preferably between 100 ° C and 180 ° C, or 180 ° C and 220 ° C for silicones. If necessary, post-crosslinking by UV or electron beam irradiation can be appropriate in order to set particularly advantageous properties of the hotmelt adhesives.
- hot-melt adhesives based on block copolymers are characterized by their wide variety of possible variations, because the targeted lowering of the glass transition temperature of the self-adhesive composition as a result of the selection of the tackifiers, the plasticizers and the polymer molecule size and the molecular weight distribution of the insert components also makes the necessary functional bonding to the skin guaranteed at critical points of the human musculoskeletal system.
- the hotmelt adhesive is preferably based on block copolymers, in particular A-B, A-B-A block copolymers or mixtures thereof.
- the hard phase A is primarily polystyrene or its derivatives
- the soft phase B contains ethylene, propylene, butylene, butadiene, isoprene or mixtures thereof, particularly preferably ethylene and butylene or mixtures thereof.
- Polystyrene blocks can, however, also be present in the soft phase B, namely up to 20% by weight. However, the total styrene content should always be less than 35% by weight. Styrene fractions between 5 wt.% And 30 wt.% Are preferred, "since a lower styrene fraction makes the adhesive more supple.
- the targeted blending of di-block and tri-block copolymers is particularly advantageous, a proportion of di-block copolymers of less than 80% by weight being preferred.
- the hot-melt adhesive has the following composition: 10% to 90% by weight block copolymers,
- tackifiers such as oils, waxes, resins, and / or mixtures thereof, preferably mixtures of resins and oils, less than 60% by weight of plasticizer, less than 15% by weight of additives, less than 5 wt% stabilizers.
- the aliphatic or aromatic oils, waxes and resins used as tackifiers are preferably hydrocarbon oils, waxes and resins, the oils, such as paraffinic hydrocarbon oils, or the waxes, such as paraffinic hydrocarbon waxes, having a favorable effect on the skin adhesion due to their consistency.
- the oils, such as paraffinic hydrocarbon oils, or the waxes, such as paraffinic hydrocarbon waxes having a favorable effect on the skin adhesion due to their consistency.
- Medium- or long-chain fatty acids and / or their esters are used as plasticizers. These additives serve to adjust the adhesive properties and the stability. If necessary, further stabilizers and other auxiliary substances are used.
- the hot melt adhesive should have a high tack.
- the functionally adapted adhesive strength on the skin and on the back of the carrier should be present.
- a high shear strength of the hot melt adhesive is necessary.
- the high shear strength of the adhesive is achieved through the high cohesiveness of the block copolymer. The good grip is due to the range of tackifiers and plasticizers used.
- the product properties such as tack, glass transition temperature and shear stability can be easily quantified with the help of dynamic mechanical frequency measurement.
- a shear stress controlled rheometer is used.
- the results of this measurement method provide information about the physical properties of a substance by taking the viscoelastic component into account.
- the hot melt adhesive is vibrated between two plane-parallel plates with variable frequencies and low deformation (linear visco-elastic range).
- a high frequency is chosen for the subjective sensation of tack (tack) and a low frequency for the shear strength.
- tack subjective sensation of tack
- a high numerical value means better grip and poorer shear stability.
- the glass transition temperature is the temperature at which amorphous or partially crystalline polymers change from the liquid or rubber-elastic state to the hard-elastic or glassy state or vice versa (Römpp Chemie-Lexikon, 9th edition, volume 2, page 1587, Georg Thieme Verlag Stuttgart - New York , 1990). It corresponds to the maximum of the temperature function at a given frequency. A relatively low glass transition point is particularly necessary for medical applications.
- the hot melt adhesives are preferably set so that they have a dynamic-complex glass transition temperature of less at a frequency of 0.1 rad / s than 15 ° C, preferably from 5 ° C to -30 ° C, very particularly preferably from -3 ° C to -15 ° C.
- Hot melt adhesives in which the ratio of the viscous portion to the elastic portion at a frequency of 100 rad / s at 25 ° C. is greater than 0.7, in particular between 1.0 and 5.0, are preferred, or hot melt adhesives in which the The ratio of the viscous component to the elastic component at a frequency of 0.1 rad / s at 25 ° C. is less than 0.6, preferably between 0.4 and 0.02, very particularly preferably between 0.35 and 0.1.
- the domes or polygeometric body shapes can have different shapes. Flattened hemispheres are preferred. Furthermore, it is also possible to print other shapes and patterns on the carrier material, for example a printed image in the form of alphanumeric character combinations or patterns such as grids, stripes, and cumulative spheres and zigzag lines.
- the adhesive can be evenly distributed on the backing material, but it can also be applied to the product in a different thickness or density over the surface, which is also favored by the possibility of varying the angle between surface and sieve according to the invention.
- All rigid and elastic fabrics made of synthetic and natural raw materials are suitable as carrier materials. Preference is given to backing materials which, after the adhesive has been applied, can be used in such a way that they meet technical requirements or the properties of a functional dressing. Textiles such as woven fabrics, knitted fabrics, scrims, nonwovens, laminates, nets, foils, foams and papers are listed as examples. These materials can also be pretreated or post-treated. Common pretreatments are corona and hydrophobizing; Common post-treatments are calendering, tempering, laminating, punching and mounting.
- the carrier material when directly coating the carrier material, it must have a certain strength and density in order to prevent the domes from penetrating too far into the carrier material or even penetrating during the coating process.
- the domes and / or polygeometric body shapes are transferred to a second carrier material after the coating.
- the second carrier material represents the actual carrier
- the first carrier material serves as an auxiliary carrier.
- Such an auxiliary carrier can also be designed in the form of an abhesively coated roller or webbing.
- auxiliary carrier is the roller with an adhesive surface, it being possible for the adhesive surface of the roller to consist of silicone or fluorine-containing compounds or plasma-coated separation systems. These can be composed having a basis weight of 0.001 g / m 2 bis 3000 g / m z in the form of a coating, preferably applied from 100 to 2000 g / m 2.
- the temperature of the abhesive surface of the roller can be set between 0 ° C. and 200 ° C., preferably below 60 ° C., particularly preferably below 25 ° C. It is particularly advantageous if the abhesive properties of the surface of the roller are matched so that the applied self-adhesive also adheres to a cooled roller ( ⁇ 25 ° C).
- Subsequent calendering of the coated product and / or pretreatment of the carrier, such as corona radiation, for better anchoring of the adhesive layer can also be advantageous.
- treatment of the hotmelt adhesive with electron beam postcrosslinking or UV radiation can lead to an improvement in the desired properties.
- the carrier material is preferably coated at a speed of greater than 2 m / min, preferably 20 to 200 m / min.
- the percentage of the area coated with the hot melt adhesive should be at least 1% and can range up to approximately 99%, for special products preferably 15% to 95%, particularly preferably 50% to 95%. This can can be achieved by multiple application, where appropriate, hot melt adhesives with different properties can also be used.
- the partial application enables the transepidermal loss of water to be removed through controlled channels and improves the evaporation of the skin when sweating, especially when using air and water vapor permeable carrier materials. This prevents skin irritation caused by congestion of the body fluids.
- the created drainage channels enable drainage even when using a multi-layer bandage.
- the support material coated in this way has an air permeability of greater than 1 cm 3 / (cm 2 * s), preferably 10 to 150 cm / (cm 2 * s), and / or a water vapor permeability of greater than 200 g / (m * 24h), preferably 500 to 5000 g / (m 2 * 24h).
- the support material coated in this way on steel has an adhesive strength on the back of the support of at least 0.5 N / cm, in particular an adhesive strength between 2 N / cm and 20 N / cm.
- the individual biomechanical adhesive force control which has a demonstrable reduction in the adhesive force of these plasters, also supports detachability.
- the applied carrier material shows good proprioreceptive effects.
- the self-adhesive compositions are foamed before they are applied to the backing material.
- the self-adhesive compositions are preferably foamed with inert gases such as nitrogen, carbon dioxide, noble gases, hydrocarbons or air or mixtures thereof.
- inert gases such as nitrogen, carbon dioxide, noble gases, hydrocarbons or air or mixtures thereof.
- foaming by thermal decomposition of gas-evolving substances such as azo, carbonate and hydrazide compounds has also proven to be suitable.
- the degree of foaming i.e. the gas content should be at least about 5% by volume and can range up to about 85% by volume. In practice, values from 10% by volume to 75% by volume, preferably 50% by volume, have proven successful. If you work at relatively high temperatures of around 100 ° C and a comparatively high internal pressure, very open-pored layers of adhesive foam are created that are particularly well permeable to air and water vapor.
- the advantageous properties of the foamed self-adhesive coatings such as low adhesive consumption, high tack and good suppleness even on uneven surfaces due to the elasticity and plasticity as well as the initial tack can be used optimally in the field of medical products.
- thermoplastic self-adhesive is reacted under high pressure at a temperature above the softening point with the intended gases such as nitrogen, air or carbon dioxide in different volume fractions (about 10 vol.% To 80 vol.%) In a stator / rotor system.
- the mixed pressures gas / thermoplastic in the system are 40 to 100 bar, preferably 40 to 70 bar.
- the PSA foam thus produced can then enter the coating nozzle via a line.
- the use of an inherently porous carrier means that the adhesive dimension coated products well permeable to water vapor and air.
- the amount of adhesive required is significantly reduced without impairing the adhesive properties.
- the adhesives have a surprisingly high tack, since per gram of mass there is more volume and thus the adhesive surface available for wetting the substrate to be adhered to, and the plasticity of the adhesives is increased by the foam structure. This also improves anchorage on the carrier material.
- the foamed adhesive coating gives the products a soft and smooth feel.
- Foaming also generally lowers the viscosity of the adhesive. As a result, the melting energy is reduced and thermally unstable carrier materials can also be coated directly.
- the outstanding properties of the self-adhesive carrier material according to the invention suggest the use for medical products, in particular plasters, medical fixations, wound coverings, doped systems, in particular for those which release substances, orthopedic or phlebological bandages and bandages.
- the carrier material can be covered with an adhesive-repellent carrier material, such as siliconized paper, or provided with a wound dressing or padding.
- the carrier material can be sterilized, preferably gamma-sterilized.
- hot melt adhesives based on block copolymers which do not contain double bonds, are particularly suitable for subsequent sterilization. This applies in particular to styrene-butylene-ethylene-styrene block copolymers or styrene-butylene-styrene block copolymers. There are no significant changes in the adhesive properties for the application.
