Abstract

The invention discloses a wollastonite powder modified flame-retardant optical cable material, which is composed of the following raw materials in parts by weight: 10 to 13 parts of wollastonite powder, 0.1 to 0.2 part of stannous sulfide, 4 to 6 parts of triethylene glycol di-2-ethylhexoate, 2 to 3 parts of octabromoether, 100 to 130 parts of polyvinyl chloride, 3 to 4 parts of polystyrene 20-2 sodium hypophosphite monohydrate, 2 to 3 parts of paraformaldehyde, 0.2 to 0.3 part of hydrochloric acid (35-37%), 4 to 6 parts of chlorinated dichloropentate, 5 to 7 parts of aluminum chloride hexahydrate, 0.1 to 0.2 part of triethylamine, 0.4 to 1 part of N,N'-ethylenebisstearamide, 1 to 2 partso f sodium gluconate, 0.1 to 0.2 part of polysorbate 80, and 0.7 to 2 parts of polyvinylpyrrolidone. The provided optical cable material can dilute the flame and reduce the temperature of combustion area; at the same time, phosphor and oxygen free radicals generated during the cracking process can capture free radicals that are generated by cracking polystyrene chain segments, thus the thermal stability of the optical cable material is improved, and the 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 a wollastonite powder modified 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 retardan...
