Abstract

The invention aims to replace wood veneer and technical wood by using a piece of novel decorative plate finishing paper for artificial plate veneering. A piece of base paper which is 150-350g / m<2> is adopted, the upper layer of the base paper is printed with simulated natural and precious trees which are infrequent day by day, other artistic patterns can be also innovated and printed, and a vivid effect can be achieved after lamination. Due to adoption of chemical fiber in the decorative plate finishing base paper, the paper strength can be improved, and the paper is soft and tough. The decorative plate finishing paper is mainly applicable to veneering of artificial plates such as fiber boards and chipboards, and can replace veneering materials such as wood veneer and technical wood, and the finishing paper can have flame retardancy after being coated with a flame retardant adhesive.

Description

technical field [0001] The invention belongs to the technical field of special paper for veneering wood-based panels, and in particular relates to a novel decorative panel veneer paper and a production method thereof. Background technique [0002] Domestic traditional wood-based panel decorative panel materials include veneer, technical wood, impregnated decorative base paper, polyolefin (Oxy) film, etc. veneer, also known as veneer, is a thin wood veneer with the characteristics of precious tree species. Or veneer materials, the common species of veneer used for furniture veneer are ash, oak, catalpa, elm, southwest birch, more precious cherry wood, black walnut, red oak and more high-end such as White shadow wood, teak, rosewood, rosewood, rosewood, etc. Technological wood is also called artificial veneer. It is a sliced ​​veneer made of rotary-cut veneer of general tree species imitating the color tone of natural wood or precious tree species, and then glued into wood ac...
