Problems solved by technology

[0002] At present, the coatings in building materials are mainly used indoors and outdoors. Most of the coatings used on indoor metal and steel structures are made of organic materials. They are poisonous and smelly in production. Once a fire occurs, they are not fireproof and can also support combustion.

Abstract

The invention relates to an inorganic fireproof coating of indoor ultrathin steel structure, which is characterized by being prepared from the following components according to the weight part: silicon powder, magnesium powder, bentonite and talcum powder which are powder material and sodium silicate which is liquid material. The preparing method of the inorganic fireproof coating is as follows: the powder material and the liquid material are mixed according to a certain proportion and uniformly stirred into milky-white liquid by a stirrer so as to be used for coating. The invention can resist the highest temperature of 1300-1400 DEG C, thereby having higher fire resistance, while common coating can resist the highest temperature of 800 DEG C; in addition, the invention innoxious, odourless and releases no harmful gas, thereby being environmental friendly; moreover, the invention has isolating effect and can prevent heat transmission, delay the temperature increase of the steel structure and improve the fireproof limitation, thereby being flame retardant.

Description

technical field [0001] The invention relates to building materials, in particular to inorganic fireproof coatings for indoor ultra-thin steel structures. Background technique [0002] At present, coatings in building materials are mainly used indoors and outdoors. Most of the coatings used on indoor metal and steel structures are made of organic materials. They are toxic and smelly during production. Once a fire occurs, they are not fireproof and can also support combustion. Contents of the invention [0003] The purpose of the present invention is to provide a non-toxic, tasteless, and fire-proof indoor ultra-thin steel structure inorganic fire-proof paint preparation method. [0004] The indoor ultra-thin inorganic fireproof paint for steel structure is characterized in that it is composed of the following components in proportion by weight. [0005] Powder: Silica powder 200-400 mesh, containing SiO 2 ≥98.72%, 3 to 12 copies; [0006] Magnesite powder 200-400 mesh, c...
