Abstract

The present invention provides a high-strength, high-temperature-resistant, fire-resistant and heat-insulating material, which comprises two unmixed A and B two components or A and B two components and three unmixed components of water, wherein the A component is an inorganic liquid High temperature resistant fireproof material, component B is inorganic powdery high temperature resistant fireproof material, wherein the inorganic powdery high temperature resistant fireproof material of component B includes high temperature resistant modified silicate powder, and ultra high temperature resistant fireproof powder, partition At least one of thermal cooling powder. Enhanced protection up to 2300°C for more than 5 hours is developed to protect the structural material from unacceptable deformation at high temperatures.

Description

technical field [0001] The invention relates to a fireproof and heat-insulating material, in particular to a high-strength, high-temperature-resistant fireproof and heat-insulating material, which belongs to the field of fireproof materials. Background technique [0002] Generally, fire and heat insulation materials, especially concrete reinforcement materials (such as steel bars) in building components, pursue continuous combustion for more than 5 hours in a high temperature environment above 1100 °C, and require that the fireproof material itself will not decompose at 1100 °C-1800 °C. The building structure composed of concrete reinforcing materials will not collapse under the combustion environment of more than 5 hours in the high temperature range of 1100℃-1800℃. [0003] As a traditional reinforcing material to protect the structure, Portland cement effectively provides fire protection for steel structures due to the high temperature resistance properties of silicates s...

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
