Abstract

The invention is a real wood skin decorating fireproof board making method, including the steps: dipping multiple layer paper with resin, where the multiple layer paper dipped has resin content of 25-60%, and then making heat pressing on the multiple layer paper at 90-200 deg.C at 50-100x10,0000Pa to form fireproof substrate; grinding the surface of the fireproof substrate and pasting the real wood skin onto the grinded surface of the fireproof substrate; coating fireproof resin on the surface of the real wood skin. It has senses of beauty and nature of natural timber and also advantages of fire safety, heat resistance, water resistance, etc.

Description

technical field [0001] The invention relates to a method for making a fireproof board. Background technique [0002] In the prior art, the fireproof board is to impregnate and dry the base paper, decorative paper and surface paper with resin respectively, and then jointly form a blank, hot press, trim and back sand to make a finished product. The bottom paper is made of multi-layered kraft paper. Since the decorative paper and the surface paper are also made of paper materials, their texture and color are printed or have a single metallic color, so their decoration is poor. Contents of the invention [0003] The purpose of the present invention is to provide a real wood veneer instead of decorative paper and surface paper, which combines the functions of the fireproof board and the decorative board, reduces the cost of decoration materials, and avoids environmental pollution caused by paint coating during decoration. ...
