Abstract

The present invention discloses an environment-friendly flame-retardant cable material, made from the following raw materials according to parts by weight: 0.1-0.2 part of silane coupling agent kh560, 4-6 parts of dioctyl sebacate, 0.1-0.2 part of pyromellitic dianhydride, 100-130 parts of polyvinyl chloride, 20-27 parts of polystyrene, 3-4 parts of sodium hypophosphite monohydrate, 2-3 parts of paraformaldehyde, 0.2-0.3 part of 35-37% hydrochloric acid, 4-6 parts of dichloropentate, 5-7 parts of aluminum oxide hexahydrate, 0.1-0.2 part of triethylamine, 0.7-1 part of isothiazolinone, 10-12 parts of montmorillonite powder, 0.7-1 part of N-sodium lauroyl sarcosinate, 2-3 parts of polyacrylamide, 0.1-0.3 part of dodecyl dimethyl betaine, and 3-4 parts of calcium aluminate. The environment-friendly flame-retardant cable material of the invention can reduce the temperature of a burning area and splits to produce some phosphorus oxygen radicals and the like that are capable of capturing free radicals generated in segment splitting of polystyrene, thermal stability of the material is improved, and heat release value of the material is reduced.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to an environment-friendly 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...
