Environment protection type composite decorative plate

Abstract

An environment protection type composite decorative board is made up of two surficial middle-density fibrous boards and central wood sheet through abrasing and flatening said central wood sheet, coating non-toxic emulsoid on the surface of said fibrous boards and wood sheet, and pressing at 0-10 deg.C (or 25-35 deg.C) under 40 tons of pressure for 20 hrs (or 12 hrs). It can not release harmful gas.

Description

technical field [0001] The invention relates to a wood-based panel used for building and interior decoration, in particular to an environment-friendly composite decorative panel beneficial to human health. Background technique [0002] The existing wood-based panels are made of blockboard and multi-layer boards. The middle of this type of board is solid wood core material. The outer layer of the wood core is horizontal wood chips, and the outermost layer is vertical wood chips. The binder is formed by hot pressing to form a five-layer plywood. This multi-layer composite board has the following problems: [0003] 1. It is harmful to human health, because its binder urine gelatin will emit a large amount of harmful gas formaldehyde after the plate is formed. [0004] 2. It consumes a lot of wood, because the front and back layers of the five-ply board must use high-quality wood, and one cubic meter of finished board needs to use 0.253 cubic meters of high-quality wood, which ...
