Fireproof vacuum insulation panel for building external thermal insulation system and preparation method thereof

Abstract

Provided are a fireproof vacuum insulation panel for a building external thermal insulation system and a preparation method thereof. The fireproof vacuum insulation panel is composed of gas-phase silica silicon carbide powder, glass fibers and a glass fiber aluminum plastic compound package bag, can be mixed with admixture, has the double functions of thermal insulation and fire resistance and can effectively resolve the problems of thermal insulation and fire resistance in an existing building external thermal insulation system. The gas-phase silica, the admixture, the silicon carbide and the glass fibers are placed in a smashing and mixing machine to be smashed and evenly mixed, then mixed materials are poured in a square hard mould to be pressed and formed, the formed compound core materials are placed in the glass aluminum plastic compound package bag to be vacuumed until the vacuum degree is smaller that 1 Pa, and the fireproof vacuum insulation panel is obtained by package. Thus, the fireproof vacuum insulation panel is simple in process, good in high temperature resistance and fireproof performance, low in heat conductivity coefficient, free of thermal treatment, short in period, low in cost, capable of effectively substituting organic cystosepiment in the existing building external thermal insulation system, and suitable for large-area preparation and large-scale production.

Description

technical field [0001] The invention belongs to the field of building thermal insulation materials, and in particular relates to a novel fireproof vacuum heat insulation board, in particular to a fireproof vacuum heat insulation board for an external heat preservation system of a building exterior wall and a preparation method thereof. Background technique [0002] With the continuous development of society and economy, energy consumption and carbon dioxide emissions are increasing year by year, resulting in the dual pressure of resource shortage and environmental damage. The Chinese government realizes the importance of energy conservation and emission reduction, and makes energy conservation and emission reduction a national policy. The energy consumption of buildings accounts for more than a quarter of the energy consumption of commodities in the whole society. One of the main ways to reduce heating and cooling energy consumption is to improve the thermal insulation perfo...

AI Technical Summary

Problems solved by technology

[0009] The main purpose of the present invention is to overcome the shortcomings of previous vacuum insulation boards such as poor high temperature resistance and fire resistance, high cost, complicated process and long production cycle, and provide a vacuum insulation board with simple process, low cost, good high temperature resistance and fire resistance. The board and its preparation method take into account both building insulation and building fire prevention, and can effectively solve the heat preservation and fire prevention problems in the external wall insulation system
