Abstract

The invention relates to a fireproof paint used for cables, which comprises the following composition by mass fraction: 100 parts of PVC resins; 5-10 parts of alumina, 2-8 parts of trioxide, 6-10 parts of melamine, 15-20 parts of sodium disilicate, 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 stabilizing agent, 25-30 parts of DOP, 3-8 parts of urea and 12-20 parts of xylene; wherein the product oxygen index is 28-30, the surface drying time is 2 hours, and the hard drying time is 20-24 hours. The fireproof paint has the advantages of low cost, good flame resistance and little toxicity. The films can be exposed to the sun and rain, and has the advantages of wear resistance as well as acid and alkali resistance, and thereby the fireproof paint can be widely produced and continuously substitutes the current 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...
