Fire retardant coating for steel structure

Abstract

The invention belongs to the technical field of fire retardant coating, and relates to a fire retardant coating for a steel structure; the fire retardant coating is composed of the following raw materials in parts by weight: 300-400 parts of 325 cement, 100-150 parts of a gypsum powder, 40-80 parts of bentonite, 100-150 parts of a heavy calcium carbonate powder, 30-50 parts of high-temperature aluminum silicate fibers, and 400-500 parts of water. During preparation, the high-temperature aluminum silicate fibers are dissolved in water to prepare a glue liquid, then the 325 cement, the gypsum powder, the bentonite and the heavy calcium carbonate powder are mixed evenly and then are mixed with the glue liquid, and stirring is carried out to obtain the coating. The coating is prepared by adopting all the inorganic, non-toxic, odorless and harmless substances, is safe and environmentally friendly, is excellent in fire resistance, has no generation of harmful gas after being heated, and is low in production cost, simple in preparation process, and suitable for wide promotion and application.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, in particular to a fireproof coating for steel structures. Background technique [0002] With the rapid development of the urbanization process, a large number of high-rise buildings rise on the ground, and the ensuing problem is how to ensure the fire safety of high-rise buildings. The current buildings are frame structure board houses, and a large amount of steel is used in the construction. , how to do a good job of fire protection on the surface of steel structures has become a top priority. General fireproof materials are added with organic flame retardants, although they can play a flame retardant effect in the event of a fire, but organic flame retardants tend to volatilize toxic gases when encountering high temperatures, which will also cause danger to the human body. Therefore, the research and development of a It is very necessary to have a special safe and environment-frien...

Problems solved by technology

[0003] The purpose of the present invention is to provide a steel structure fire retardant coating for the problem that many of the fire retardant coatings currently used in buildings contain organic flame retardants, which tend to volatilize toxic substances when encountering high temperatures and cause harm to the human body.
