Definitions
- the invention relates to a method for producing adhesion promoter layers a sheet material and the use of the adhesion promoter layers, in particular for adhesive tapes.
- adhesive layers on sheet-like materials for a variety different applications.
- Examples are packaging materials, Adhesive tapes or protective films, in which adhesion promoter layers in each case are provided in order to achieve sufficient strength of the layer composite.
- Adhesive tapes this is often particularly problematic since generally high Requirements for the adhesion between adhesive and backing material are made. Detachment of the adhesive from the backing should not occur when the adhesive tape is detached from the roll (before use) while removing the tape from any Surfaces (after use) take place.
- Adhesion-promoting layers also known as primers can, for example, as a wet chemical coating from solution (Solvent or water) are applied, followed by drying and / or networking is necessary.
- Another disadvantage of flame pretreatment is the high thermal stress on the treating materials, so that in particular temperature-sensitive materials cannot be treated or can only be treated to a limited extent.
- the low-pressure plasma pretreatment which is carried out with non-polymerizing gases (e.g. Noble gases, oxygen or nitrogen), it is generally possible better adhesion than with flame or corona treatment.
- non-polymerizing gases e.g. Noble gases, oxygen or nitrogen
- the high costs for the necessary vacuum equipment are problematic especially in the treatment of sheet materials.
- Low-pressure plasma polymerization has not yet been used for the industrial production of adhesion-promoting layers applied to sheet-like materials, although for resting substrates already processes for a multitude of different applications exist. Examples are the coating of plastic bottles with permeation barrier layers or the scratch-resistant coating of plastic surfaces. With web-shaped The use of low-pressure plasma polymerization has generally been materials so far not useful, since the deposition rates are too low, so that coating time of Minutes or hours. For this is the manufacture of coatings by means of low-pressure plasma polymerization in the case of sheet-like materials, in particular the production of adhesive layers, uneconomical.
- primers that are applied by wet chemistry usually brings high cost, since the priming of the web-like material means a complete additional coating process.
- the use of wet chemical primers is also problematic in the case of rough web-shaped ones Materials, since in these cases it is difficult to maintain a constant, even To achieve layer thickness.
- temperature-sensitive materials can only to be coated with wet chemical primers to a limited extent, since economical primer drying drying temperatures when processing sheet materials of at least 80 ° C is required.
- Another problem is when a certain layer, for example one Layer of adhesive, on a certain sheet material with none of the known methods can be brought to liability sufficiently well.
- the object of the invention is to avoid the disadvantages of the prior art, at least diminish.
- it is the object of the invention in the case of adhesive layers
- Significant increase in adhesion to sheet-like materials achieve the increase in adhesion must be long-term stable, no solvents to be used and the process and the adhesion-promoting layers should be harmless to health and the environment.
- the task is solved by a method for producing adhesion promoter layers on sheet-like materials, as is characterized in more detail in the main claim.
- the subclaims relate to particularly advantageous embodiments of the Procedure.
- the invention relates to the use of the adhesion promoter layers, especially with adhesive tapes.
- the invention relates to a method for producing adhesive layers on a web-shaped material, characterized in that the preferably almost or completely transparent adhesive layers by means of low-pressure plasma polymerization can be applied to the web-shaped material by the web-like material is continuously passed through a plasma zone in which a low-pressure plasma is present, which is due to electrical discharge, in particular kHz, MHz or GHz discharge is generated.
- Important process parameters that affect the process of depositing the adhesive The monomers used control layers and thus the layer properties or carrier or additional gases, the gas or gas mixture pressure during the coating and the electrical discharge used for plasma excitation.
- the variation of Process parameters serve to optimize and adapt the adhesion promoter layers to the technical boundary conditions in the respective application. Especially can be selected by appropriate selection of the process parameters, as in the examples explains a significant increase in the deposition rate compared to the state of the Technology can be achieved so that coating times are less than 1 second surrender.
- Coating is preferably carried out at a gas pressure or gas mixture pressure of 10 -3 to 20 mbar.
- the coating times are shorter than one minute, in particular less than a second.
- the unwinding station of the web-like material, the rewinding station and the plasma zone is in a vacuum chamber (batch operation) or the sheet-like material is guided through the plasma zone by means of vacuum locks becomes what is known as so-called air-to-air operation.
- saturated hydrocarbons with chain lengths from C 1 to C 6 in particular methane, ethane or propane, and / or mono- or polyunsaturated hydrocarbons with chain lengths from C 1 to C 6 , preferably acetylene or ethylene, and / or or oxygen- or hetero-element-substituted compounds of the saturated or unsaturated hydrocarbons, such as, for example, ethylene oxide.
- Non-polymerizable gases such as. are preferably used as carrier or additional gases Noble gases, oxygen, hydrogen, nitrogen or compounds respectively Gas mixtures used.
- Additional and carrier gases are used to control the layer deposition and in particular to increase the uniformity and stability of the plasma.
- Adhesion promoter layers produced by the method with at least one-sided adhesive tapes to promote adhesion between the carrier and adhesive.
- a strong improvement in adhesion is particularly typical for the combination of sheet-like materials and adhesives based on acrylate.
- Various forms of electrical discharge can be used for plasma excitation become. This is preferably done by kHz, MHz or GHz discharge.
- Crucial for the selection of the form of excitation are the procedural boundary conditions, for example necessary coating speed or gas mixture pressure, during the coating.
- a particular advantage of the method compared to the prior art is the possibility the process of layer deposition and thus the adhesive effect of To be able to control coatings by varying the process parameters. This makes possible an optimal adaptation of the layer properties to the respective application.
- Another advantage of the novel process is the absence of solvents and the Possibility of using substances from a health or environmental point of view are to be avoided.
- An additional advantage of the process is the ability to use rough sheet materials to be coated evenly with adhesive layers.
- the thermal load on the sheet materials is due to the Low pressure plasma used low, so that in particular temperature sensitive Materials such as polyethylene, polypropylene or foams coated without damage can be.
- Another advantage is the high long-term stability of the new adhesive layers, because these are highly cross-linked and thermally stable due to the new process. In addition, these are insoluble in common solvents, so that their use, in particular to promote adhesion between sheet-like materials and wet-chemical applied Coatings, leads to very good results.
