A fire retardant coating for cables

Abstract

A kind of fireproof coating for cables, its composition expressed in parts by mass is: 100 parts of polyvinyl chloride resin; 5-10 parts of aluminum oxide; 2-8 parts of antimony trioxide; 6-10 parts of melamine; 15-20 parts of sodium silicate; 2-5 parts of titanium dioxide; 15-25 parts of calcium carbonate; 20-25 parts of decabromodiphenyl ether; 4-6 parts of tetrabromobisphenol A; 1-3 parts of light stabilizer parts; DOP25-30 parts; urea 3-8 parts; xylene 12-20 parts; product oxygen index 28-30; surface dry 2h, hard work 20-24h; low cost, good fire resistance, low toxicity; coating film is not afraid of the sun Sun and rain, wear-resistant acid and alkali can be widely produced and continuously replace existing materials.

Description

technical field [0001] The application belongs to the field of fireproof materials, in particular to a fireproof coating for cables. Background technique [0002] The research and development of China's cable fire retardant coating products began in the late 1970s and early 1980s. It was developed on the basis of decorative fire retardant coatings combined with its own requirements. Its physical and chemical properties and weather resistance are better, and the coating is thinner. In case of fire, it can form a uniform and dense spongy foam insulation layer, which has a significant effect of heat insulation and fire prevention, so as to achieve the purpose of protecting cables, preventing the spread of flames, and preventing the occurrence and development of fires. As an important product for cable fire protection, cable fire retardant coating has played a positive role in reducing cable fire losses and protecting people's property safety through application in the past 20 y...
