Problems solved by technology

It has been widely produced and applied in China, has made due contributions to my country's fire protection and construction, and has received good social and economic benefits. Solvent-based ultra-thin steel structure fire retardant coatings use organic solvents , a large amount of solvent volatilizes in the process of production, construction and early use, which brings a great burden to the environment, causes a great waste of resources, and seriously affects the health of personnel in the process of production and construction. At the same time, in production and There is also a huge fire hazard hidden in the construction process

Abstract

The invention relates to a waterborne super thin steel structure fireproof coating and a preparation method Which is evidently different from the solvent-typed expansion foam fireproof coating, the invention solves the problems of environmental pollution, resource waste and high cost in prior solvent-typed super thin steel structure fireproof coating. The invention takes water as solvent and comprises the components with certain weight portions: water of 5-25 weight portions, waterborne resin or mixed waterborne resin of 10-30 weight portions, waterborne expansion additive of 25-50 weight portions, pentaerythritol or dipentaerythritol or starch of 5-15 weight portions, one or two components among urea, melamine and dicyano diammonium with 6-15 weight portions, ammonium dihydrogen phosphate, ammonium polyphoste or diammonium phosphate of 15-30 weight portions, expansion regulator of 3-18 weight portions, titanium dioxide of 3-12 weight portions, dispersion agent of 0.1-1.0 weight portions.

Description

Technical field: [0001] The invention relates to the expanded foaming ultra-thin fireproof coating for steel structures and its preparation method. Background technique: [0002] With the construction speed and construction style requirements of modern industrial plants, commercial buildings, office buildings, and office buildings, steel structures are widely used. However, steel structures without fire protection will reach the softening point in a short period of time in a fire and lose their support. The disadvantage of collapse due to strength, this weakness must be overcome by external protection, and fire protection coating for steel structures is one of the most commonly used and most effective means in fire protection of steel structures. Compared with other fire protection technologies for steel structures, no matter It has obvious advantages in the process of production, construction, maintenance, etc., that is, the steel structure fireproof coating has a short pro...
