Definitions

  • the invention relates to the field of adhesive films, an adhesive being releasably located on a release film or on a carrier film and being transferred to a substrate using pressure.
  • the invention thus relates to a method for producing a web-like carrier material provided on one side with an adhesive coating and, as an intermediate product, a coating substance for application to the carrier material.
  • the carrier material can be, for example, paper, a plastic film or a metal film, which may have been siliconized.
  • a backing material is known from DE 94 07 704U which, instead of the full-surface adhesive coating, has a coating of individual points.
  • a punctiform coating has the advantage that a smooth tear-off line can be achieved when the adhesive coating is applied to the base, because "threading" does not occur in the areas not coated with adhesive material between the adhesive points.
  • the punctiform coating of the carrier material is usually carried out by printing processes, for example in the case of “hot melts”, in particular by flexographic printing processes (cliché roller application). These processes are very complex and expensive.
  • the object of the present invention is therefore to provide a rapid coating method which enables a point-like coating of a carrier material with an adhesive and which is also inexpensive and easy to handle. Another object is to provide an adhesive with which the method according to the invention can be carried out.
  • the punctiform coating is applied to the carrier material by a coating device known per se.
  • the coating device In its conventional application, the coating device is used for full-area and homogeneous coatings. Surprisingly, it has been shown that the same coating device can also be used for coating carrier materials with punctiform coatings.
  • the coating device for homogeneous coating, however, according to the invention there is a suitable selection and combination of the properties of the adhesive and of the carrier material and the process parameters which may be determined, so that a coating consisting essentially of a non-uniform dot pattern is achieved instead of a homogeneous layer.
  • the selectable operating parameters of the coating device are suitably adapted to the respective materials of the adhesive and the carrier material in order to obtain the above-mentioned point-like coating pattern.
  • a full-surface adhesive provides the highest adhesive strength.
  • the method according to the invention provides film-like carrier materials coated with an adhesive, which according to the method provide such a high point density of adhesive that they come closer to the ideal full coverage of 100% than is possible with conventional machine printing methods, such as gravure printing or flexographic printing would. Nevertheless, the above-mentioned disadvantageous behavior of full-surface coatings, such as "threading", was not observed.
  • an embodiment of the invention will be described with reference to the accompanying drawings.
  • Figure 2 shows schematically the structure of a further roller doctor
  • Figures 3 to 5 show different arrangements for a doctor blade in a coating process.
  • the coating device comprises a trough 1 in which the liquid coating substance 2 is located.
  • a cylindrical application roller 3 is introduced into the coating substance 2.
  • the axis of the application roller is located slightly above the surface of the coating substance 2 and runs perpendicular to the sheet plane in FIG. 1.
  • the application roller 3 is set in rotation by a motor about its axis. In Figure 1, this rotation is counterclockwise.
  • the coating device further comprises two deflection rollers 4, 5 and a pressure roller 6.
  • the axes of the deflection rollers 4, 5 and the pressure roller 6 each run parallel to the axis of the application roller 3.
  • the deflection roller 5 and the pressure roller 6 are each perpendicular to their axis in the vertical direction displaceable.
  • a web-like carrier material 7 to be coated is guided over the two deflecting rollers 4, 5.
  • the carrier material 7 is drawn off at its end, which lies in front of the first deflecting roller 4, from a supply spool (not shown in FIG. 1). At its other end.
  • the carrier material is wound up by a winding device onto a cylindrical sleeve (not shown in FIG. 1).
  • the coating is wound up via a rotatable chill roll with a spreading effect and a drive device.
  • the drive device sets the cooling roller in a rotational movement about its axis, as a result of which the carrier material 7 is drawn off the supply reel, guided over the deflection rollers 4, 5 and wound onto the take-up reel.
  • a doctor blade 8 is attached between the pressure roller 6 and the second deflection roller 5.
  • the doctor blade 8 consists of a thin rod with a kind of external thread.
  • the rod axis runs parallel to the axes of the application roller 3.
  • the roller doctor blade can also be formed by a thin rod, on the outside of which a thin wire is wound.
  • a comma doctor blade as in FIG. 2 and other arrangements of the roller doctor blade as in FIGS. 3 to 5 can also be used.
  • the doctor blade 8 is arranged so that its vertical position is approximately on the imaginary connecting line between the two lowermost ends of the two deflection rollers 4 and 5.
  • the pressure roller 6 can be displaced in the vertical direction in such a way that, in a lower position, it presses the carrier material 7 both onto the top of the doctor blade 8 and onto the top of the application roller 3.
  • the coating substance 2 is applied to the carrier material 7 in the following way:
  • the application roller 3 rotates, part of the coating substance 2 remains on the outside of the application roller 3.
  • the coating substance 2, which adheres to the outside of the application roller 3 can be applied over the entire surface to the underside of the carrier material 7.
  • a flat coating of the carrier material 7 is achieved by pulling the carrier material 7 over the deflection rollers 4, 5 by means of the winding device.
  • a more or less homogeneous layer of the coating substance forms on the underside of the substrate on the substrate 7. The thickness of this homogeneous layer depends essentially on the properties of the coating substance and the surface of the carrier material.
  • the underside of the carrier material 7 is then pulled over the doctor blade 8.
  • the squeegee 8 is set in rotation by a motor about its axis. Alternatively, the doctor blade 8 can also stand still.
  • the doctor blade 8 strips part of the full-surface layer from the carrier material 7.
  • the stripped coating substance 2 then flows back into the tub 1.
  • the remaining coating substance remaining on the carrier material 7 normally forms a homogeneous layer there.
  • liquid drops form on the surface of the carrier material.
  • the size and the spacing of the drops which form on the underside of the carrier material 7 also essentially depend on the properties of the doctor blade 8, in particular on their thread depth or the thickness of the wire wound on the doctor blade 8.
  • a drying section is arranged between the guide roller 5 and the winding device. After the carrier material is drawn over the deflection roller 5, it runs through this drying section, which can be heated. The liquid coating substance dries on the carrier material 7.
  • the coating substance 2 As mentioned above, it essentially depends on the properties of the coating substance 2 and the surface properties of the carrier material 7 whether a homogeneous layer or irregularly arranged individual drops form on the carrier material 7 after the coating. In the case of droplet formation, the droplet size and the spacing of the droplets depend in particular on the coating substance 2 and the surface properties of the carrier material 7.
  • the formation of the drops of the coating substance 2 on the carrier material 7 essentially takes place through a suitable selection of the properties of the coating substance 2 and the surface of the carrier material 7. It is important that the surface tensions of the coating substance 2 and the carrier material 7 are coordinated with one another such that at least 2 drops are formed on the carrier material 7 below a certain surface density of the coating substance.
  • the coating substance 2 according to the invention is an adhesive dispersion comprising: a) an adhesive mixture composed of the following constituents minus water, 2 to 12% of a butyl polyacrylic acid, 1 to 5% of a copolymer of acrylonitrile and an acrylic acid ester, 40 to 95% of an acrylic ester containing carboxyl groups, 0 to 50% of a polyvinyl acetate, 0 to 2% of a defoamer, 0 to 5% of an agent for adjusting the pH and 20 to 50% by weight of water, based on the mixture consisting of a) and b).
  • the adhesive dispersion according to the invention comprises 4 to 10% by weight of butyl polyacrylic acid, 2 to 4% by weight of a copolymer of acrylonitrile and alkyl acrylate , 50 to 90 of an acrylic acid ester copolymer containing carboxyl groups.
  • the defoamer can be present at 0 to 2% by weight, in particular 0.5 to 1.8% by weight.
  • the pH adjustment agent generally requires an amount in the range of 0 to 5%.
  • Polyether derivatives of fatty acids can be used as defoamers. So-called “disperses” are used as agents for adjusting the pH. These are generally nitrogen-containing, alkaline compounds, for example amino alcohols, in particular 2-amino-2-methylpropanol (plus 10% water) or organic amines, for example alkylamines or ammonia solutions.
  • the water content of the coating substance 2, i.e. the adhesive dispersion is 20% to 50% by weight, preferably 25 to 45% by weight, in particular 30% to 43%, and more preferably 35 to 40%. Accordingly, the proportion of solids is 50% to 80%, preferably 55% to 75%, in particular 57% to 70%, more preferably 60% to 65%, in each case based on the total adhesive dispersion.
  • Plastic films for example made of polyethylene terephthalate, polybutylene terephthalate, polybutylene terephthalate, triacetate, polyamide, polyimide, polycarbonate, PVC, polypropylene, polyethylene, celluloceacetate, polyacrylate, but also made of metal, for example aluminum or copper, optionally siliconized, can be used as the carrier material 7.
