Definitions

  • the invention relates to a method and a device for the continuous coating of plastic floor coverings with a structured surface, in particular of structured PVC floor coverings, with a surface finish.
  • Plastic floor coverings with a structured surface are used to a large extent today as floor surfaces, above all because of their diverse decorative surface design and their extensive resistance to wear and tear.
  • PVC floor coverings are used to a large extent today as floor surfaces, above all because of their diverse decorative surface design and their extensive resistance to wear and tear.
  • Such effective initial maintenance of the installed flooring is, however, only very rarely carried out on site by the supplier.
  • the cases in which the buyer does such initial care in the "Do it your self" process after the floor covering has been laid are also exceptional. If such initial care is carried out at all, it is very often inadequate. incorrect or done too late. and above all, it is carried out without an adhesion-enhancing heat.
  • WO 82/02 681 describes a process for the production of a decorative film material by printing a polyvinyl film with a plurality of pigment-based plastisols, a transparent plastic layer being knife-coated onto the decorative pattern layer after the last printing process and before hardening, and then the entire layer structure is dried in an oven.
  • the literature reference does not show that the surface of the base material is even.
  • the invention is based on the object of creating a method and a device of the type mentioned at the beginning. with which it is possible in a simple and inexpensive way to produce a floor covering that is already professionally provided with a uniform anti-soiling finish on the surface with a layer thickness of 1-50 ⁇ m, as a result of which the above-mentioned difficulties and phenomena no longer occur at the end customer of the floor covering can.
  • the coating of the floor covering surface in a fresh, wettable state is intended to achieve particularly good adhesion and particularly good durability of the protective film, which is otherwise not possible with the conventional methods.
  • This object is achieved in that the coating of the surface of the floor covering in the factory. subsequent to the manufacture of the flooring.
  • a polymer dispersion based on pure acrylates in conjunction with corresponding temporary and permanent plasticizers or as a solvent-containing coating agent is applied to the floor covering by means of a roller system as an aqueous coating agent, or an organosol based on acrylate or polyurethane.
  • the surface design of the coating applied to the structured flooring is uneven. which is why the applied coating is first blown using a gas stream, e.g. B. air is evened out to get a uniform layer thickness of the order on the finished flooring. Then the still moist coating on the floor covering is dried, hardened and fixed by means of thermal radiation.
  • a gas stream e.g. B. air
  • the method according to the invention is suitable for coating endless floor coverings with a surface finish with a web width of the floor covering of more than 4 meters.
  • the throughput speed of the floor covering can be 1 to 80 m / min.
  • a throughput speed of 10 to 30 m / min has proven to be particularly suitable.
  • the layer thickness of the application on the structured flooring is even and adjustable from about 1 to 50 ⁇ m. With a layer thickness of 3 to 20 ⁇ m, the desired effect is already fully achieved in most cases.
  • a device for performing the invention The method is characterized by the features of claim 3.
  • 1 denotes the structured floor covering web to be tapered from the production process.
  • a trough 2 contains the aqueous and / or solvent-containing coating agent 3.
  • a roller 4 is immersed and takes a corresponding proportion of the coating agent with it.
  • the coating agent entrained by the roller 4 is then transferred to the surface of an application roller 5 rotating in the opposite direction of rotation.
  • the structured floor covering is pressed against this application roller 5 by a deflecting roller 6 and the coating agent is accordingly applied to the surface of the floor covering.
  • d. H. to accomplish.
  • the coating film is applied to the entire surface of the structured floor covering, in particular also to the lower lying areas, it has proven to be advantageous that the application roller 5 has a closed, smooth rubber surface.
  • the coated floor covering 7 is guided past a nozzle 9 by means of a further deflecting roller 8 in order to homogenize the application layer, by means of which a gas stream, e.g. B. air, the surface of the application layer blows, whereby a flat surface of the coating is formed.
  • a gas stream e.g. B. air
  • the coated floor covering with its still flowable application layer is then guided past a heating device 10 and the applied layer is dried, hardened and fixed.
  • a heating device a heat radiation source, for. B. uses an IR radiator field.
  • This process not only dries the coating applied to the top of the floor covering as anti-soiling equipment. but the effect of heat also ensures good adhesion between the floor covering and the coating.
  • a 4.08 meter wide track of a chemically shaped one. structured CV flooring is fed to an impression roller at a throughput speed of 20 m / min.
  • This dispersion is about 20% by weight of polymethyl methacrylate and is pumped around with the corresponding dispersion located in a storage container.
  • dispersion By means of a rotating steel roller immersed in the dispersion, dispersion is continuously taken out of the tub and transferred to an application roller which has a rubber coating.
  • the surface of the CV floor covering is covered with a thinner, coherent, endless. coated on the structured surface of the covering.
  • the CV floor covering coated in this way is then guided past an air nozzle via a deflection roller. which blows the still wet application with an air flow of around 40 ° C and smoothes the application.
  • the uniform dispersion film is then passed onto the CV floor covering by an IR radiator field, which has an output of 2 x 8,000 Kcal / m2 (2 x 33,500 KJ / m2), and the dispersion film is dried in the process. hardened and fixed on the surface of the CV flooring. After the last process, the coating has a thickness of approximately 6 ⁇ m, which corresponds to an application weight of approximately 30 g / m 2 of coating film.
  • the CV floor covering which is equipped with the anti-soiling equipment, is then rolled up on a supply roll.
  • a floor covering in particular a structured PVC floor covering, which is provided with anti-soiling equipment immediately after the production process, with good adhesion between the floor covering and the coating being achieved.
  • a uniform coating of the floor covering is achieved. the deeper areas of the structuring also being provided with the coating agent. The design is not affected and the degree of gloss or matt of the surface of the floor covering due to the covering can, if necessary, also be retained.
