Abstract

The invention relates to a mica-based fireproof coating for steel structures, the raw materials of which include the following main components in parts by mass: 15-25 parts of mica, 15-30 parts of metal hydroxide, 5-12 parts of ethanol, and 7-7 parts of calcium carbonate 10 parts, 15-25 parts of talcum powder, 6-12 parts of silane, 6-12 parts of siloxane, 5-8 parts of glass sand, and 5-8 parts of resin. The present invention uses mica and metal hydroxide as a composite combination, so that the fire-resistant coating can not only have flame-retardant properties, but also maintain fire-proof capabilities such as flame-resistant, flame-resistant and flame-retardant, and can effectively protect surrounding flammable materials.

Description

technical field [0001] The invention relates to a fireproof coating, in particular to a polyorganic acid-based fireproof coating used for fireproofing steel structures. Background technique [0002] At present, fire prevention measures at home and abroad are divided into dredging method and interception method in principle, and interception method is divided into outsourcing sealing method, shielding method and spraying method. Fireproof material is widely used as a material coated on the surface of objects with functions of heat insulation, fire prevention and flame retardancy. It can effectively delay the development of fire and prevent the spread of flame when used in building materials. [0003] The patent application of application publication number CN103923545A discloses a kind of fireproof coating. The coating is non-toxic and non-irritating, and has good adhesion, beauty and good flame-retardant effect when coating. Existing fireproof coatings often have shortcomi...
