Abstract

The invention discloses a high-strength flame retardant optical cable material. The high-strength flame retardant optical cable material is prepared from the following raw materials in parts by weight: 10-13 parts of stalactite powder, 0.1-0.2 part of dibenzothiazyl disulfide, 0.8-1 part of manganese iso-octoate, 100-130 parts of polyvinyl chloride, 3-4 parts of polystyrene 20-2 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 aluminium chloride hexahydrate, 0.1-0.2 part of triethylamine, 1-2 parts of sodium fluosilicate, 2-3 parts of poly-4-methyl-1-pentene, 3-5 parts of diisodecyl adipate, 1-2 parts of antimonous oxide, 0.2-0.4 part of cocinic acid diethanol amide and 0.1-0.2 part of trithiocyanuric acid. The high-strength flame retardant optical cable material can realize the effects of diluting flame and lowering temperature of a combustion region, phosphorous and oxygen free radials produced during cracking can capture free radials produced during cracking of a polystyrene chain section, thermal stability of the material is improved, and thermal 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 high-strength 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 properties. ...
