Abstract

The invention relates to a fireproofing paint for a steel structure based on tetrahydrophthalic acid diglycidyl ester. The fireproofing paint comprises the following key components in parts by mass: 15-25 parts of tetrahydrophthalic acid diglycidyl ester, 15-30 parts of metal hydroxide, 5-12 parts of ethanol, 7-10 parts of calcium carbonate, 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. By taking the tetrahydrophthalic acid diglycidyl ester and the metal hydroxide as a composite, the fireproofing paint provided by the invention can keep the fireproofing capabilities such as flame resistance, flameproofing, flame retardancy and the like in addition to the fire resistance, and can effectively protect surrounding inflammable 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...
