Description

technical field [0001] The invention relates to a coating, in particular to a novel fireproof coating. Background technique [0002] Steel does not have flammability, but the thermal conductivity of steel is large, and the thermal conductivity at room temperature reaches 58.2W / m·K. When the fire or heat temperature reaches about 500°C, the elastic modulus, yield strength and ultimate strength of the steel will be significantly reduced, and the strain will increase sharply, resulting in rapid distortion and deformation, resulting in partial or complete collapse of the steel structure. Experiments have shown that steel has the characteristics of heat resistance but not high temperature resistance, and as the temperature increases, the strength of steel will gradually decrease. For example, under the action of fire, when the temperature of steel structural members reaches 350°C, 500°C, and 600°C, the strength will drop by 1 / 3, 1 / 2, and 2 / 3 respectively. Once the temperature r...
