A-grade fireproof and heat insulation sandwich plate and processing method thereof

Abstract

The invention relates to an A-grade fireproof and heat insulation sandwich plate and a processing method. The technical path is as follows: the first step: firstly enabling non-fireproof foam particles to become A-grade fireproof foam particles; the second step: then enabling the A-grade fireproof foam particles to become an A-grade fireproof foam plate; and the third step: and further enabling the A-grade fireproof foam plate to become the A-grade fireproof foam sandwich plate. The processing method specifically comprises the following steps: performing wrapping, covering and fireproof modification on the ordinary commercially available polystyrene foam particles through three layers of different composite additives, and firstly preparing the A-grade fireproof and heat insulation polyphenyl foam plate; and then respectively coating and brushing a layer of composite adhesive on each of the upper surface, the lower surface and the periphery of the A-grade fireproof and heat insulation polyphenyl foam plate, and performing processing, rolling and covering or wrapping and preparing on a metal material surface layer or an inorganic composite surface layer by special equipment.

Description

technical field [0001] The invention relates to new building material technology and the application field of energy saving and emission reduction, in particular to a class A fire-proof, thermal-insulation sandwich panel and a processing method thereof. Background technique [0002] At present, energy conservation and emission reduction, low-carbon environmental protection, have become an important topic and strategic task common to all mankind, and the energy consumption of buildings is very large, accounting for more than half of the total energy consumption. Building insulation is an effective means to solve building energy consumption and necessary condition. [0003] In contrast, the foam sandwich panel made of expandable polystyrene foam is the best cost-effective thermal insulation building material for industrial plants and temporary buildings. The only disadvantage is that it is flammable. The lack of fire prevention has caused many catastrophic fire accidents, whi...

[0003] In contrast, the foam sandwich panel made of expandable polystyrene foam is the best cost-effective thermal insulation building material for industrial plants and temporary buildings. The only disadvantage is that it is flammable. It is not fireproof, causing many catastrophic fire accidents, seriously affecting its application, so that its use is completely banned due to choking and waste food, and a large number of existing polystyrene foam sandwich panel processing factories have closed down.
