Waste-utilized environment-friendly fireproof heat-insulating material

Abstract

The invention relates to building materials and specifically relates to a waste-utilized environment-friendly fireproof heat-insulating material for walls. The waste-utilized environment-friendly fireproof heat-insulating material is prepared from the following raw materials in percentage by weight: 24% to 44% of waste refractory glass fiber composite filter bags, 28% to 20% of leftover materialstrimmed during the production of filter bags from refractory glass fiber composite felt, 28% to 36% of talcum powder, 4% to 6% of flocculant and 4% to 6% of cationic starch. Both the waste refractoryglass fiber composite filter bags and the leftover materials trimmed during the production of the filter bags from the refractory glass fiber composite felt have base fabrics, i.e., glass fiber base fabrics and surface layers, i.e., glass fiber composite surface layers. According to the waste-utilized environment-friendly fireproof heat-insulating material, waste raw materials serve as main raw materials and are recycled, so that the cost is reduced, and land resources are saved; the waste-utilized environment-friendly fireproof heat-insulating material is free of harmful gas emission, has good high-temperature resistance, corrosion resistance and low hygroscopicity, is light in weight, small in coefficient of thermal conductivity, good in suction performance and good in chemical stabilityand is non-combustible.

Description

technical field [0001] The invention relates to a building material, in particular to an environment-friendly fire-proof and heat-retaining material utilizing waste materials 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 ...

[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.
