Problems solved by technology

In recent years, although different types of fireproof boards, fireproof doors and other fireproof products have appeared, some of these products do not meet the fireproof requirements and cannot solve the actual problem of fireproofing. Some consume a lot of high-quality wood, and some It is the treatment of the material. Once the treatment is not good, it will cause pests, especially some of the adhesives can not meet the requirements of environmental protection and safety performance, which will pollute the environment.

Abstract

The invention relates to a multilayer perlite composite flame-retardant sheet. The flame-retardant sheet has a laminated structure containing at least three layers, wherein the surface layer is a wooden layer, a middle wooden layer is separated from a flame-retardant layer, adhesive is used between the layers; the wooden layers are processed through conventional flame-retardant treatment, the thickness is 1-5mm; the thickness of the flame-retardant layer is 1-120cm and comprises the following components by weight: 10-25kg of expanded perlite with 1.5-3mm of particle diameter, 25-40kg of magnesium chloride, 10-25kg of magnesium oxide, 100-300kg of sodium phosphate, 150-350kg of lithopone, 0.1-2.0kg of emulsifier and 50-200kg of adhesive, wherein magnesium chloride, magnesium oxide, sodium phosphate, lithopone, emulsifier and adhesive are used as auxiliary material and filler. As flame-retardant treatment is preformed to the wooden layers and the flame-retardant layer is prepared by mixing expanded perlite and adhesive, the flame-retardant sheet is fire-retardant, wood is saved, no pollution is caused, and the flame-retardant sheet is free from any insect and is the best replacement of the existing shaving board, fiber-board, core-board, solid wood board and other materials.

Description

technical field [0001] The present invention relates to a plywood, in particular to a multi-layered perlite composite flame-retardant compound composed of wood as the main or only component of a thin layer, which is attached to another thin layer composed of a specific substance plate. The present invention also relates to a method for manufacturing the above-mentioned multi-layer perlite composite flame-retardant board. Background technique [0002] The fire protection of wooden materials has always been an important topic in the field of construction. In recent years, although different types of fireproof boards, fireproof doors and other fireproof products have appeared, some of these products do not meet the fireproof requirements and cannot solve the actual problem of fireproofing. Some consume a lot of high-quality wood, and some It is the treatment of the material. Once it is not handled properly, it will cause pests, especially some of the adhesives in it can not m...
