Problems solved by technology

[0003] Steel is mostly used in modern buildings. Although steel itself does not burn, the mechanical strength of steel decreases with the increase of temperature. At 500-600°C, its strength decreases by 30-40%. The weight, yield point, load capacity, etc. all drop rapidly, and they can't play a supporting role, causing the building to collapse.

Abstract

The invention discloses a fire retardant coating, which comprises the following components: an environment-friendly solvent, weather-proof acrylic resin, chlorinated polyether resin, flame retardant amino resin, a dispersing agent, composite foaming powder, a flame retardant material A, titanium white, a flame retardant material B, a flame retardant aid, wood fibers, an inorganic microbead hollowfiller and an anti-sagging agent. The invention also provides a preparation method for the fire retardant coating. The fire retardant coating can be coated on various substrates, is extra-thin, efficient and durable, is specially used outdoors, is resistant to the fire combustion of hydrocarbons, and has high chemical properties such as weather resistance, acid resistance, alkali resistance and the like, high adhesion and an attractive decorative effect, and paint films are fine; the fire retardant coating is uniformly expanded, and has a special foam structure and a high fireproof effect; and the product is environment-friendly and pollution-free, a production process is simplified, and the fire retardant coating is convenient to construct and can be used for coating with various fireproof requirements.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a fireproof coating and a preparation method thereof. Background technique [0002] In recent years, many large-scale fires have occurred, causing huge property losses and casualties, such as the previous Shanghai Jing'an high-rise building, the new CCTV building, etc. Therefore, the country attaches great importance to the fire protection requirements of materials. All fire-fighting products must be strictly tested and certified, and can only be approved for production after meeting the requirements set by the Ministry of Public Security for fire-fighting products. At present, the country has only set up two authoritative inspection institutions - Tianjin Fire Research Institute and Sichuan Dujiangyan Fire Research Institute to conduct quality supervision and inspection of fire protection products. With the large-scale development of urban construction, the applicat...
