Definitions
- the invention relates to an iron soleplate, consisting of a good heat-conducting metal, preferably aluminum, with a coating of a hard material component, preferably metallic or ceramic materials, arranged on the ironing side.
- an iron soleplate is described in the earlier American patent application, serial no. 06 / 759.406.
- an iron soleplate made of aluminum is used.
- the aluminum soleplate due to its reduced weight compared to conventional materials such as steel or iron, enables the soleplate to slide more easily on the items to be ironed.
- the surface of the temple side was in the above-mentioned patent application by a Flame or plasma spray process coated hard material component, which preferably consists of metallic or ceramic materials.
- the hard material layer produced here by spraying has the disadvantage that it is porous and that it absorbs in particular water, moisture, air and other contaminants that can penetrate to the aluminum sole. This results in corrosion on the aluminum surface on the temple side, which can lead to the formation or blistering and even detachment of the hard material layer. The consequence of this is damage to the ironing side of the iron soleplate, which leads to fabric damage when ironing the ironing material and causes increased shifting forces on the iron.
- the object of the invention is therefore to provide an iron soleplate which is extremely scratch-resistant with good sliding properties, which is abrasion-resistant and easy to clean, which is resistant to corrosion and temperature and which allows simple and inexpensive production.
- the ceramic or metallic hard material layer is coated with a particularly lubricious, anti-adhesive and sealing organic binder.
- the hard material layer applied, for example, by flame or plasma spraying or by another economical coating method to the metal side of the iron soleplate is, due to such methods, permeated with pores and fine channels.
- the pores and fine channels of the hard material layer are sealed off by the applied binder, so that the iron material which escapes when it is ironed escapes from it when ironing Steam cannot penetrate the hard material layer, which prevents corrosion damage to the soleplate.
- the arrangement according to the invention is also of great advantage in particular in the case of steam irons, since the steam emerging from the steam outlet openings cannot cause any corrosion damage to the soleplate of the iron.
- the soleplate created by the invention also withstands greater mechanical forces that can sometimes occur during ironing. Due to the anti-adhesive and sealing coating of the hard material layer, it is almost impossible for dirt residues to be deposited on the side of the bracket. Should the soleplate of the iron be contaminated by burned-in material or plastic particles, the surface can easily be cleaned easily with a hard sponge, with a steel wool or even with a special cleaner, etc. and without great effort, without the surface showing signs of wear or deteriorating properties shows visible scratches.
- the micro image of the rough surface structure on the hard material layer is designed in such a way that the elevations are smoothed.
- This further development of the soleplate according to the invention ensures that the elevations which are present on the surface after the hard material layer has been sprayed and are recognizable as peaks under the microscope are blunted.
- the surface does not look like a very fine sandpaper, but it is sufficiently easy to slide and does not cause any noticeable wear on the items to be ironed. The roughness is therefore reduced.
- This smoothing process carried out on the surface of the hard material layer also serves there to make it easier for the binder to form a closed protective film on the surface of the hard material layer and for the depressions which are still present to achieve an additional improvement in the adhesive properties of the binder. It has been shown in practice that if the surface structure of the hard material layer after the smoothing process has an average roughness of 5 to 10 microns, a particularly resistant, well sliding iron soleplate results. In accordance with DIN 4768, mean roughness depth is understood to mean the mean value of the individual roughness depths of five successive individual measurement sections.
- a hard material layer thickness of less than 100 ⁇ m, preferably 40 to 50 ⁇ m only slight mechanical stresses form in the hard material layer when exposed to heat, which are absorbed by a targeted porosity of 3 to 10% and by the elastic properties of this layer.
- the stresses are mainly generated by temperature changes in the soleplate (aluminum). If the hard material layer were too thick, stress cracks would occur, which would result in this layer lifting off or crumbling. The iron would then be unusable.
- a minimum layer thickness is required in order to achieve a sufficient load-bearing capacity or resistance to mechanical influences on the relatively soft surface of the aluminum sole.
- these advantages are improved to a particularly significant extent in accordance with the invention in that the hard material layer is so thinly coated by the binder that the surface structure of the hard material layer on the surface of the binder coating is essentially retained.
- the surface of the temple side thus has a ge targets the desired medium roughness. If the binder is applied too thickly on the hard material layer, this increases the gliding properties of the soleplate, but it loses scratch resistance because burrs can be easily introduced into the relatively soft binder layer compared to the hard material layer, which, as already mentioned at the beginning State of the art mentioned lead to peaks on the surface of the binder layer. These burrs formed by the raised parts are not too resistant, but they are enough to damage particularly delicate textiles.
- the surface of the hard material layer is coated by the binder such that the troughs formed due to the roughness are filled by the binder and that the area determined by the highest, ground tips of the wave crests, which the Wing of the soleplate forms, is in turn only covered with a thin film.
- This type of sealing has the advantage that, due to the still very thin application of the binder layer to the areas of the hard material layer forming the wing, a particularly smooth iron soleplate is created. Even scratching down the hard material layer is very difficult, despite the thin coating, since this is prevented by the adhesive forces present between the binder layer and the hard material layer.
- the thicker the binder layer in the area of the wing the more elastic its surface and the easier it is that the binder layer can be removed in these areas.
- the binder layer is consequently hard and wear-resistant with this type of application.
- the width of the wave troughs must not be too large, since then the comparatively large accumulation of the binder in the wave troughs results in a comparatively large bulge of the binder layer between the individual wave crests on the wing. This would lead to the undesirable side effect that above the wave crests, where the bulge is less than above the wave troughs, there are depressions in which bow remnants can be deposited.
- the average thickness of the film of the binder layer is below 10 ⁇ m, preferably between 0.1 and 2 ⁇ m.
- an iron soleplate at room temperature when ironing on cotton (DIN 53919) has friction values between 0.12 and 0.20. If the sole is heated for ironing, the binder layer emerges from the interface due to thermal expansion, which leads to a drop in the coefficient of friction.
- Binder resins enriched with PTFE or PFA or silicone are particularly suitable as binders. These materials are also in Connection with binder resin is particularly slippery, has a high temperature resistance and adheres well to the soleplate due to the roughness depth design according to the invention.
- the PTFE, PFA or silicone particles in the binder resin rise to the surface of the binder layer. This means that there is hardly any PTFE, PFA or silicone content in the lower layers of the binder layer. The result of this is that these parts are removed from the surface relatively quickly when ironing.
- a filler preferably barium sulfate
- the binder consists of 40 to 50% binder resin, 5 to 10% filler and the rest of PTFE or PFA or silicone. Since the filler exhibits particle-like behavior and therefore increases friction when it comes into contact with the ironing material, the proportion of filler added must not be too high. Because the adhesive strength of the binder to the hard material surface is determined neither by the PTFE content nor by the filler, but solely by the binder resin, the filler content must not be too high for this reason either. So that almost exclusively binder resin is deposited on the hard material surface for the purpose of good adhesive strength, a slight increase in the PTFE content is even desirable, but only until the surface of the hard material layer is almost free of PTFE content.
- the binder is particularly easy to creep in the diluted state, so that the pores and finer channels in deeper regions of the hard material layer are sealed.
- the invention provides that Binder is colorless and transparent. This ensures that the color of the hard material layer shows through.
- a preferred dark gray to black color is achieved in that the hard material layer consists of a mixture of Al2O3 and TiO2, the mixing ratio being about 2: 1.
- any gray values can be achieved with these components in correspondingly different mixing ratios.
- With a mixing ratio of approximately 97: 3, a light gray iron soleplate is created.
- the specified low roughness on the ironing side of the soleplate results in a matt, glossy surface that is particularly insensitive to dirt and slides well.
- colorless binder is more sensitive and not as stable in its mechanical consistency as compared to the colored binders, it has been shown in practice that excellent results are achieved with the binder according to the invention and that there is no discoloration on the items to be ironed due to the lack of color pigments.
- An adhesion promoter layer which preferably consists of an alloy of nickel and aluminum, is advantageously arranged between the surface of the highly thermally conductive metal and the hard material layer.
- the adhesion promoter layer can be applied over the entire area or even only in such a way that there are isolated empty spaces. The adhesive promotes better adhesion of the hard material layer on the soleplate.
- the iron soleplate according to the invention is produced in that the hard material layer is surface-treated before the binder is applied.
- mechanical surface treatment has proven to be particularly cost-effective, by means of which the desired roughness depth can also be exactly maintained.
- the surface of the hard material layer can also be treated in several operations in such a way that predominantly only the peaks of the highest elevations of the surface structure are removed. This operation can advantageously be carried out with a not too hard hard material layer, that is to say with a mixture ratio of about 2: 1 or less (Al2O3: TiO2), with a brush tool, through which the surface of the hard material layer is smoothed in the shortest possible time.
- cleaning is carried out in a further advantageous embodiment of the invention by a combined pressure and suction bubble method or by an ultrasound method in aqueous solution in order to obtain a fat-free surface.
- the roughness on the surface of the binder layer essentially Lichen corresponds to the roughness of the surface of the hard material layer.
- the dosage of the binder can be accomplished particularly simply by electrostatically spraying the binder onto the surface of the hard material layer.
- the electrostatic spraying process enables an extremely fine spray jet in which the droplets generated can penetrate directly into the pores and into the fine channels of the hard material layer due to their good creeping ability, so that the binder covers the surface structure with an almost uniform film.
- the particularly spreadable binder which consists for example of PTFE or PFA or silicone and binder resin, is mixed with a thinner. The volatile thinner evaporates shortly after the binder has been sprayed on, so that PTFE or PFA or. Silicone parts are included.
- the binder it is advantageous for the binder to be heat-treated by infrared radiation, for example with the aid of a quartz lamp, in order to harden the soleplate of the iron.
- infrared radiation for example with the aid of a quartz lamp
- curing of the binder layer takes place for the first time in a much shorter time. Due to the shorter curing time of the binding agent and the fact that the soleplate is not heated as a whole, but only locally on its surface, gas expansion in the cavities (pores, blowholes) of the cast iron soleplate cast from aluminum is largely avoided.
- FIG. 1 the surface of the iron soleplate 1 is shown in cross-section, with the corresponding subsections 2 to 9 following each work step, running from top to bottom the structure of the surface is shown. Beginning in each case from the surface 10, each section 2 to 9 only runs to a depth of the base body 12 of the iron soleplate 1, which is made of aluminum, as shown by the breaking line 11, since the sections are shown greatly enlarged.
- the base body 12 made of aluminum can have been produced from aluminum by any of the generally known casting methods.
- the fracture lines 13, 14 which run vertically in the sections 2 and 3 in the drawing indicate that part of the layer thickness of the base body 12 has been omitted in this area. This was necessary so that the surfaces 10 and 17 present in the partial areas 2 and 3 could also be shown on the drawing. In the cross section of the aluminum base body 12, inclusions, cavities or other pores 15 can be seen, which are inevitably formed when aluminum is cast.
- the surface 10 After the casting of the base body 12, the surface 10 has an average roughness depth of 10 to 20 ⁇ m. The surface 10 can then be blasted for cleaning and deburring purposes. In subsection 3, surface 17 then has the structure shown.
- the surface 17, or in the event that no blasting is carried out the surface 10 is ground so far that the resulting surface 18 has an average roughness depth of approximately 0.6 to 4 ⁇ m, in particular between 1 and 2 ⁇ m, having.
- the grinding process is necessary because the base body 12 after the casting process due to the temperature drop warp and therefore its surface 10 can be curved.
- the surface 18 is cleaned of oxides and other impurities by corundum blasting or a similar surface treatment method and then gives the surface 19 shown in subsection 5.
- An adhesion promoter 16 such as nickel aluminum (NiAl), is then applied to the surface 19 for further treatment in a flame or plasma spraying process.
- the proportion of aluminum (Al) in this alloy is preferably 29 to 33%.
- the purpose of the adhesion promoter layer is, in addition to a mechanical connection of the hard material layer 20 to the base body 12, to also produce a diffusion connection between the purely ionically bound hard material layer and the purely metal-bound aluminum base body 12.
- the NiAl particles form regions 32 which, depending on the amount of material applied, produce a closed (FIG. 2) or no closed (FIG. 1) adhesion promoter layer 16 on the surface 19.
- a closed adhesion promoter layer 16 its average roughness is preferably 10 to 20 ⁇ m with an average thickness of approximately 12 ⁇ m.
- a ceramic or metallic hard material layer 20 is then applied to the areas 32 and the partially uncovered (FIG. 1) or to the closed surface 19 (FIG. 2) by flame or plasma spraying.
- the surface 21 produced in this way has an average roughness depth of 10 to 20 ⁇ m.
- the thickness of the hard material layer 20 is less than 100 ⁇ m, preferably 40 to 50 ⁇ m. 1, the material of the hard material layer 20 penetrates into the vacancies 22 formed between the regions 32 and thereby also covers the surface 19.
- the measure material of the hard material layer 20 engages behind both with an adhesive layer 16 according to FIG. 1 and according to FIG.
- the porosity pores 28 and channels 30
- This porosity is between 3 and 7%, preferably 5%.
- the adhesion promoter layer 16 also contributes to voltage equalization.
- the surface 21 of the hard material layer 20 due to the manufacturing process, has particularly sharp-edged tips of the wave crests 23 (FIG. 1), these are removed in a subsequent mechanical surface treatment, such as polishing, brushing or sleeving, up to a predetermined height.
- the resulting surface 29 is shown in the section 8.
- the surface defined by the highest ground tips of the wave crests 23 forms the wing 33 of the soleplate 1.
- the average roughness depth is reduced from 10 to 20 ⁇ m to approximately 5 to 10 ⁇ m; the lower lying regions of the troughs 25 are not or only slightly influenced.
- the penultimate operation is followed by the spraying of an organic binder 26, as shown in section 9.
- the organic binder consists of a mixture of PTFE or PFA or silicone with a binder resin, a filler that causes an even distribution of the PTFE, PFA or silicone particles in the binder resin, and a thinner.
- the binder layer 26 can be sprayed on so thinly (FIG. 1) that the subsequent average roughness of the binder layer 26 remains almost unchanged from the average roughness of the hard material layer 20 specified in subsection 8. In this case, the binder 26 is thus applied in the wave troughs 25 as well as on the wave crests 23 with approximately the same layer thickness.
- the binder layer 26 shown in FIG. 2 arises from the fact that so much binder 26 is applied that the troughs 25 are filled with binder 26 and that the surface defined by the highest ground tips of the wave crests 23, which forms the support surface 33 of the iron soleplate 1, again is only covered with a thin film.
- the hard material layer 20 has a large number of inclusions or pores 28 and fine channels 30 which would allow liquid and dirt to penetrate if the binder layer 26 did not prevent this.
- the channels 30 result from the fact that the hard material layer 20 is constructed in the form of a sheet by the flame or plasma spraying process.
- the incorporation of the binder 26 in the deeper layers of the hard material layer 20 is shown in the section 9.
- the ironing side 27 of the soleplate 1 is irradiated infrared so that the binder 26 can dry out and harden. Due to the infrared radiation, the surface 27 of the soleplate 1 is heated so quickly that the binder layer 26 is cured in a very short time, without there being a disadvantageous expansion for the soleplate 1 as a result of the heating in the aluminum base body 12.
- the surface 27 of a binder layer 26 designed according to FIG. 2 has a scratch, a groove or a similar injury 34, which has resulted in the binder layer 26 having been removed there except for the hard material layer 20.
- the iron soleplate 1 When the iron soleplate 1 is heated, a self-healing effect occurs with regard to the injury 34 in that the material of the binder layer 26 embedded in the two troughs adjacent to the injury 34 literally grows upward beyond the contour of the surface 27 due to the temperature increase (cf. bulges 35 and 36). During ironing, this material is displaced by the frictional action that occurs and fed to the injury 34, as a result of which the binder layer 26 is restored at the site of the injury 34.
