Decorative composite board for buildings

Abstract

The invention discloses a decorative composite board for buildings, which comprises a wear-resistant layer, a decorative layer and a base material layer, all the layers are sequentially connected through bond, the decorative layer comprises a decorative base layer, a wood grain printed layer and wood grain-imitating raised parts, the wood grain printed layer is arranged upon the decorative base layer and printed with a wood grain-imitating pattern, the wood grain-imitating raised parts are arranged on the surface of the wood grain printed layer, color ink is solidified to form the wood grain-imitating raised parts, a waterproof layer is arranged on the surfaces of the wood grain-imitating raised parts, one side of the base material layer is provided with a groove for mounting, and the other side of the base material layer is provided with a tongue for connection with the groove. The wear resistance of the decorative board is effectively enhanced by means of the arranged wear-resistant layer, the waterproofness of the decorative board is effectively enhanced by means of the arranged waterproof layer, and the wood grain pattern is vivider and more three-dimensional because of the arranged wood grain-imitating raised parts.

Description

technical field [0001] The invention relates to a decorative composite board for building. Background technique [0002] There are several types of decorative composite panels known in the past for construction: [0003] (1) After the embossed pattern is printed with an ink with a large solid content such as a pigment by the usual printing method on the substrate, a varnish composed of an amino alkyd resin or a polyurethane resin is used to form a pre-coated paper on the surface; [0004] (2) On the substrate, a pattern composed of usual printing ink and ink containing a foaming agent is printed, and the pattern part is raised by the foaming agent to obtain a decorative plate; [0005] (3) Lay a transparent plate on the printing surface of the colored substrate with pattern printing, and form a decorative plate with concave and convex clusters in this process according to the situation; [0006] (4) A resin decorative board obtained by printing a pattern on a substrate imp...

AI Technical Summary

Problems solved by technology

[0009] (1) In the past, pre-coated paper formed concave-convex patterns by printing. Due to the poor printing adaptability of the ink, there were restrictions on the color tone and concentration, so the required concave-convex patterns could not be fully reflected

In addition, varnishes such as amino alkyd resin and polyurethane resin that make up the surface resin layer are hard and brittle, so the amount of coating cannot be increased, and the abrasion resistance is poor;

[0010] (2) Decorative boards with raised parts using foaming agents can reflect three-dimensional patterns in design, but most of them use thermoplastic dendritic polyethylene, which has problems of poor wear resistance and heat resistance

In addition, it is difficult to obtain a decorative board with a natural pattern similar to wood grain because it is formed by the uplift of the pattern itself.
