Abstract

The invention discloses an ultraviolet-resistant flame-retardant optical cable material which is composed of the following raw materials in parts by weight: 0.6-1 part of 2-(2'-hydroxy-5'-tert-octylphenyl)benzotriazole, 100-130 parts of polyvinyl chloride, 20-27 parts of polystyrene, 3-4 parts of sodium hypophosphite monohydrate, 2-3 parts of polyformaldehyde, 0.2-0.3 part of 37-37% hydrochloric acid, 4-6 parts of chlorospirophosphate, 5-7 parts of aluminum chloride hexahydrate, 0.1-0.2 part of triethylamine, 10-12 parts of graphite powder, 4-6 parts of polyvinyl butyral resin, 0.1-0.3 part of magnesium oxide, 0.6-1 part of dimethyl chlorophthalate, 1-2 parts of calcium palmitate, 0.1-0.2 part of lauryldimethylamine oxide, 0.3-0.5 part of ethylene glycol monobutyl ether and 0.6-2 parts of aluminum dihydrogen phosphate. The ultraviolet-resistant flame-retardant optical cable material can perform the function of lowering the temperature of the combustion zone, and some phospho-oxygen free radicals and the like generated during pyrolysis can capture free radicals generated by polystyrene segment pyrolysis, thereby lowering the heat release value of the material.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to an anti-ultraviolet and flame-retardant optical cable material and a preparation method thereof. Background technique [0002] In recent years, nanotechnology has attracted widespread attention in the field of flame retardancy. Studies have shown that nanomaterials only need a small amount of addition (generally less than 5%) to achieve a more obvious flame retardancy effect. Therefore, the preparation of flame-retardant nanocomposites is an important component in the field of flame-retardant technology, and is highly regarded by researchers. Layered inorganic nanomaterials are one of the most effective filler materials in flame-retardant nanocomposites. When layered inorganic nanomaterials are dispersed in the polymer matrix at the nanoscale, they can significantly improve the mechanical properties of nanocomposites. , thermal stability and flame retardant prope...
