Abstract

The invention discloses fire-retardant paint of an organosilicone modified epoxy acrylate ultrathin steel structure and a preparation method of the fire-retardant paint. The fire-retardant paint is prepared from 35-71% of expansive fire-retardant system, 10-28% of inorganic fire-retardant system, 5-13% of titanium dioxide, 17-37% of modified emulsion base material and 15-20% of auxiliaries and water. The fire-retardant paint is prepared by means of the grinding, mixing and rapid stirring method. The fire-retardant paint has good adhesion, weather resistance and intumescent flame retardant effect and is safe, environmentally friendly, low in cost, friendly to the environment, small in amount, convenient to construct and excellent in decoration performance.

Description

technical field [0001] The invention relates to a fireproof coating for steel structures, in particular to an organosilicon-modified epoxy acrylate ultra-thin fireproof coating for steel structures and a preparation method. Background technique [0002] The so-called fireproof coating for steel structure is a functional coating that is applied to the surface of the steel structure of buildings and structures and can form a fire-resistant and heat-insulating protective layer to improve the fire resistance limit of the steel structure. According to the thickness of the coating, there are three types of fireproof coatings for steel structures: thick coating (H type), thin coating (B type) and ultra-thin (CB type). [0003] Due to the traditional solvent-based CB-type steel structure fireproof coatings, VOCs (volatile organic compounds) are seriously harmful to the human body and the environment, and there is a problem of large smoke and dust during the flame retardant process. ...
