Abstract

The invention relates to a silicon nitride-based fireproof coating for wires and cables. The raw materials include the following main components in parts by mass: 15-25 parts of ethylene acrylic acid copolymer, 15-30 parts of metal hydroxide, and 12-30 parts of silicon nitride. 18 parts, 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. In the present invention, ethylene acrylic acid copolymer and metal hydroxide are used as a compound combination, and silicon nitride is added to make the fire retardant coating not only have flame retardant properties, but also maintain fire resistance, flame resistance and fire resistance, and can effectively protect Surrounded by 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...
