Abstract

The invention relates to improved fire-retardant coating. The improved fire-retardant coating is prepared from the following components in parts by weight: 8-25 parts of film forming agent, 0.5-5 parts of inorganic hollow filler, 5-36 parts of acid donor, 2-28 parts of carbon donor, 1-21 parts of a foaming agent, 1-8 parts of synergist, 10-20 parts of melamine, 20-40 parts of deionized water, 2-10 parts of talc powder, 5-20 parts of sodium silicate, 5-10 parts of titanium dioxide, 1-5 parts of expanded vermiculite, 1-5 parts of pentaerythritol and 1-10 parts of mica powder. The improved fire-retardant coating has the advantages that the adhesive strength can be remarkably improved since the adhesive force of the fire-retardant coating is less than 1 grade; the fire retardant time of the fire-retardant coating is between 30 and 35 minutes at a high temperature of 800 DEG C, so that the high temperature resistance is remarkably reinforced, more valuable time is gained for rescuing and fire extinguishing; and the production cost is low, and the manufacture method is simple.

Description

technical field [0001] The invention relates to a coating, in particular to an improved 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 temperatu...
