Fireproof thermal insulation material

Abstract

The invention relates to a building material, and concretely relates to a fireproof thermal insulation material for walls. The fireproof thermal insulation material comprises the following raw materials, by weight, 24-44% of a waste high temperature resistant glass fiber composite filter bag, 28-20% of a scrap obtained by cutting when the filter bag is produced from high temperature resistant glass fiber composite felts, 28-36% of coal ash, 4-6% of a flocculating agent and 4-6% of cationic starch, wherein base clothes of the waste high temperature resistant glass fiber composite filter bag and the scrap obtained by cutting when the filter bag is produced from the high temperature resistant glass fiber composite felts are glass fiber base clothes, and surface layers of the composite filter bag and the scrap are glass fiber composite surface layers. Main raw materials of the invention are waste raw materials, so the recycle of the waste raw materials makes the cost and the land resource be saved; and no harmful gases are discharged, and the fireproof thermal insulation material has the advantages of good high temperature resistance and corrosion resistance, low water absorbability, light weight, small conduction coefficient, good productivity, no combustion and good chemical stability.

Description

technical field [0001] The invention relates to a building material, in particular to a fireproof and thermal insulation material for walls. Background technique [0002] Although the current external wall insulation technology can meet the requirements of building energy conservation, the insulation materials used such as EPS board, XPS board and rigid foam polyurethane have low ignition points, are easy to catch fire, and are difficult to rescue in case of fire. In recent years, several fires in high-rise buildings in China were caused by unqualified wall insulation materials, causing huge property losses and casualties. The flammable external insulation materials used in buildings have become a new fire hazard. Moreover, when these materials are burned, they produce toxic and harmful gases, causing harm to people, polluting the environment, and causing huge losses to the country and people's life and property. Therefore, it is urgent to solve the fire prevention problem o...

[0002] Although the current external wall insulation technology can meet the requirements of building energy conservation, the insulation materials used such as EPS board, XPS board and rigid foam polyurethane have low ignition points and are easy to catch fire, and it is difficult to rescue them in case of fire.

In recent years, several fires in high-rise buildings in China were caused by unqualified wall insulation materials, causing huge property losses and casualties. The flammable external insulation materials used in buildings have become a new fire hazard.

Moreover, when these materials burn, they produce toxic and harmful gases, which cause harm to people, pollute the environment, and cause huge losses to the country and people's lives and property. Therefore, it is urgent to solve the fire prevention problem of the external thermal insulation system.
