Abstract

The invention discloses a rubber-plastic blended flame-retardant optical cable material, which is composed of the following raw materials in parts by weight: 0.6 to 1 part of zirconium fluoride, 3 to 5 parts of ethylene glycol dimethacrylate, 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, 7 to 9 parts of fluorapatite, 0.2 to 0.5 part of hexabromocyclododecane, 1 to 2 parts of amino trimethylene phosphonic acid, 1 to 1.7 parts of zinc ricinoleate, 0.3 to 1 part of butyltin mercaptide, 2 to 3 parts of ammonium polyphosphate, 0.1 to 0.2 part of alkylated diphenyl amine, 1 to 3 parts of allyl polyethylene glycol, and 4 to 6 parts of ethylene propylene diene monomer. The provided optical cable material can dilute the flame and reduce the temperature of combustion area; 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 plastic blended 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....
