The reinforced heat-resistant optical cable filler composition disclosed by the invention comprises the following components: 2,4-imidazolidinone, tripropylene glycol monomethyl ether, octamethylcyclotetrasiloxan, octaphenyl-POSS, tetramethylammonium hydroxide, dimethylacetamide, octaphenylcyclotetrasiloxane, 4,4'-diaminodiphenyl ether, 20-25% of ammonium hydroxide, a high temperature regulator, benzenetetracarboxylic anhydride, aramid fibers, N-methyl-2-pyrrolidone, modified high density polyethylene, dibutyl phthalate, polyisobutene, zinc pyrithione, silicon carbide, trimethylethoxylethylenediamine, nylon, epoxidized soybean oil, aresistance agent and silicon dioxide thickening poly alpha-olefin. The reinforced heat-resistant optical cable filler composition disclosed by the invention is excellent in bending performance and anti-pressure ability, excellent in thermal stability, radiation stability and mechanical protectiveness, high in anti-pressure ability, capable of well avoiding external environment damage and long in storage time.

Description

Technical field: [0001] The invention relates to the technical field related to communication materials, in particular to an enhanced heat-resistant optical cable filler composition. Background technique: [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That is: a cable...
