Example Embodiment

[0048] In the preparation process of the traditional PVC floor composite material, the PVC base plate is obtained by pressing and pasting the PVC base plate and the PVC film at high temperature to obtain the PVC board base material, and then UV-cured coating is made on the PVC board base material to obtain the finished PVC flooring product. The PVC floor coating obtained by this process has poor adhesion, and the paint is easily peeled off locally, which affects the appearance of the PVC floor; in addition, the PVC floor produced by some textured PVC floors sometimes tends to have uneven gloss; Paint coating is done on the PVC film first, and the obtained PVC pre-coating film is directly pressed and pasted with the PVC bottom plate at high temperature to obtain a PVC floor. The application of the present invention finds that not just doing paint on the PVC film can obtain a qualified PVC pre-coating film. The coating film and PVC pre-coating film have cracking during rewinding,...

Abstract

The invention relates to the technical field of floor surface decoration materials, and particularly provides a PVC precoated film and a preparation method thereof. The PVC precoated film comprises atransparent PVC film layer and a radiation-cured coating layer from bottom to top, the radiation-cured coating layer sequentially comprises an adhesion primer layer, an elastic primer layer, a functional layer and a finish paint coating layer from bottom to top, the adhesion primer layer and the elastic primer layer adopt specially designed formulas, and the functional layer and the finish paint coating layer adopt common coating formulas, wherein the adhesion primer layer is prepared from a bifunctional polyurethane acrylate resin, a vinyl chloride-vinyl acetate resin, a bifunctional acrylatemonomer and a solvent. The adhesion bottom layer and the elastic bottom layer cooperate with the flexible PVC film material, so improve the adhesive force between the PVC film and the coating layer of the PVC precoated film is improved, the PVC precoated film can be pressed and formed on the PVC floor at a high temperature subsequently, and the problems of whitening, cracking, yellowing and the like are avoided, thereby a favorable material basis is provided for simplifying processing and production of a traditional PVC floor composite material.

Description

technical field [0001] The invention relates to the technical field of floor surface decoration materials, and more specifically, the invention provides a PVC pre-coating film and a preparation method thereof. Background technique [0002] PVC floor is a new type of light-weight floor decoration material that is very popular in the world today. It has the advantages of green environmental protection, super wear resistance, various designs and colors, and quick installation and construction. It is used in hospitals, schools, office buildings, Shopping malls, supermarkets, transportation and other places have been widely used and highly recognized. [0003] In actual use, in order to meet consumers' requirements for different performances such as wear resistance, scratch resistance, and strength of the PVC floor surface, various functional coatings are often added to the surface of the PVC floor to meet different consumers' requirements for different types of floors. demand, ...
