Problems solved by technology

For example, "a kind of UV varnish" disclosed by the Chinese patent whose publication number is CN101096558A has high hardness, it is difficult to achieve excellent flexibility, and it is easy to crack after film formation. In addition, the adhesion is not satisfactory.
The "UV paint that can produce special patterns" disclosed by the Chinese patent with the authorized announcement number CN100595247C, although it has good flexibility, is not suitable for the veneering process in furniture processing.

Abstract

The invention provides an UV (ultraviolet) photo-cured acrylic resin composition which comprises the following components: thermoplastic acrylic resin, polyurethane modified epoxy acrylic resin, bisphenol A epoxy acrylic resin, an reactive diluent and acrylate phosphate, and the UV photo-cured acrylic resin composition can further comprise auxiliaries and a photoinitiator. The UV photo-cured acrylic resin composition has the advantages of excellent flexibility, high temperature resistance, excellent adhesion on various types of wood veneers, no powder material in the formula, excellent definition and the like, and can be directly used on a roller coating machine for construction, and other diluents do not need to be additionally added; so that UV paint has a wider range of applications.

Description

technical field [0001] The invention relates to a resin composition, in particular to an acrylic resin composition applied to a UV elastic primer on a wood veneer surface. Background technique [0002] In the production of wooden furniture, in order to beautify the appearance of the product, improve the performance, protect the surface, and increase the strength, medium and high-end furniture or wood products must be surface-decorated or veneered (wood veneer). Veneering is to paste the veneer glue with the characteristics of precious tree species on the surface of the base material or panel parts, so that the surface of the parts can retain the excellent characteristics of wood and have a realistic sense of natural wood grain and color. It is a high-end decorative veneer process . When the veneer is pasted in the furniture factory, a certain temperature needs to be applied to the veneer to promote the melting of the hot melt adhesive to make it bond to the veneer and the M...
