Abstract

The invention relates to a fire-retardant coating based on polycarborane methylsiloxane, the raw material of which comprises the following main components in parts by mass: 15-25 parts of bis(2,3-epoxycyclopentyl) ether resin, 15-30 parts of metal hydroxide, 5-12 parts of ethanol, 7-10 parts of calcium carbonate, 15-25 parts of talc, 6-12 parts of polycarborane methylsiloxane, 5-8 parts of glass sand, 5-8 parts of resin. The present invention uses bis(2,3-epoxycyclopentyl) ether resin and metal hydroxide as a composite combination, and then adds polycarborane methyl siloxane, so that the fireproof coating has flame retardant properties and also It can maintain fire resistance such as flame resistance, flame resistance and flame retardancy, 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 for indoor fireproofing. 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 shortcomings such as sho...
