Abstract

The invention provides a hydrocarbon-resistant indoor ultrathin fireproofing coating for steel structures. The fireproofing coating consists a component A and a component B, wherein the component A is composed of highly chlorinated polyethylene, TBBP, ammonium polyphosphate, melamine, pentaerythritol, antimonous oxide, chlorinated paraffin, titanium dioxide and a mixed solvent, and the component B is polyamide 300#, and the components A and B are mixed at 1.5:(9-10) in percentage by mass. The fireproofing coating has characteristics of strong adhesion force, good film forming performance, excellent combustion and expansion, high hardness of carbon layer, being anti-corrosive and anti-rust, hydrocarbon fire resistance and the like, and the fireproofing coating is free from toxicity, smell and release of harmful gas.

Description

technical field [0001] The invention relates to the technical field of metal surface coatings, in particular to a hydrocarbon-resistant indoor ultra-thin fireproof coating for steel structures. Background technique [0002] Most of the frames of modern high-rise and large buildings use steel structures, but steel as a building material has unavoidable defects in fire protection, such as yield point, tensile strength and modulus of elasticity, etc. will drop sharply due to the increase of temperature, thus The loss of bearing capacity can easily cause the collapse of the building. Therefore, it is often necessary to apply fire-resistant coatings to construction steel to ensure construction quality and durability. [0003] There are many types of fireproof coatings for steel structures, which are mainly divided into three types: thick, thin and ultra-thin according to the thickness of the coating. Among them, thin and ultra-thin fireproof coatings have become fireproof due to...
