High-strength high-temperature-resistant fireproof thermal insulation material

Abstract

The invention provides a high-strength high-temperature-resistant fireproof thermal insulation material which comprises a component A and a component B which are not mixed with each other or a component A and a component B which are not mixed with each other and water, the component A is an inorganic liquid high-temperature-resistant fireproof material, and the component B is an inorganic powdery high-temperature-resistant fireproof material, the inorganic powdery high-temperature-resistant fireproof material of the component B comprises high-temperature-resistant modified silicate powder, and at least one of super-high-temperature-resistant fireproof powder and heat-insulating cooling powder. And a reinforced protection effect at the highest temperature of 2300 DEG C for more than 5 hours is formed, so that a structural material is protected from unacceptable deformation influence caused by high temperature.

Description

technical field [0001] The invention relates to a fire-proof and heat-insulating material, in particular to a high-strength, high-temperature-resistant fire-proof and heat-insulating material, which belongs to the field of fire-proof materials. Background technique [0002] Generally, fire-proof and heat-insulating materials, especially concrete reinforcement materials (such as steel bars) in building components are pursued to burn continuously for more than 5 hours in a high-temperature environment above 1100°C, and it is required that the fireproof material itself will not decompose at 1100°C-1800°C. It makes the building structure composed of concrete reinforcement materials not collapse in the burning environment in the high temperature range of 1100°C-1800°C for more than 5 hours. [0003] As a traditional reinforcing material to protect structures, Portland cement can effectively provide fire protection for steel structures due to the high temperature resistance of sil...

Problems solved by technology

However, since the silicate chemical bond (-Si-O-, 108kj / mole) is decomposed at 1160°C, it is difficult for the fireproof material mainly made of Portland cement to survive the high-temperature combustion of 1100°C for more than 5 hours.

[0004] Considering the traditional Portland cement-based fireproof coating, polymer resin is used to strengthen the bonding force between Portland cement powder and the polymer resin pre-coated on the surface of the steel structure, and there will be crack penetration heat in the high-temperature combustion environment of the fireproof material. And lead to the problem of cracking and peeling of polymer resin, thus losing the function of providing long-term fire protection for steel structures
