Abstract

The invention discloses a fireproof coating for an ultra-thin type steel structure building. The coating is characterized by being prepared from, by weight, 40-60 parts of II type ammonium polyphosphate, 20-45 parts of melamine, 18-30 parts of sodium tripolyphosphate, 15-25 parts of dicyandiamide, 1-5 parts of cyclohexanone, 6-10 parts of coking benzene, 13-20 parts of dipentaerythritol, 5-10 parts of red lead powder, 12-18 parts of mica powder, 3-8 parts of zinc powder, 12-20 parts of titanium dioxide, 25-40 parts of talcum powder, 15-28 parts of wollastonite powder, 3-10 parts of swell soil,8-15 parts of chlorinated paraffin, 5-10 parts of expanded graphite, 20-30 parts of matrix resin, 1-3 parts of addition agent and 10-25 parts of deionized water. The fireproof coating for the ultra-thin type steel structure building has the advantages that the formulation is simple, the cost is low, the coating is non-toxic and non-polluting, the fireproof performance is excellent, the coating can play a good role in protecting the steel structure, the viscosity of the coating is finer, the coating is thinner, the decorativeness is better, not only is the requirement of fireproofing satisfied, but also the demand of the market for the decorativeness is satisfied.

Description

technical field [0001] The invention relates to a fireproof coating for ultra-thin steel structure buildings. Background technique [0002] Ultra-thin steel structure has the advantages of light weight, high strength, convenient construction, good ductility and earthquake resistance, and is increasingly widely used in the construction industry, especially in super high-rise and long-span buildings. vitality. [0003] However, the ultra-thin steel structure has poor fire resistance and is very easy to conduct heat. Many steel structure building fire cases at home and abroad have proved that within 20 minutes after a fire breaks out, the building will be burned and collapsed. Therefore, the fire protection problem of steel structure buildings has attracted the attention of the world. [0004] Ultra-thin steel structure fireproof coating refers to steel structure fireproof coating with a coating thickness of no more than 3mm. This kind of fireproof coating expands and foams ...
