Abstract

The invention discloses a communication optical cable jacket material for hot and humid areas and a preparation method thereof. The communication optical cable jacket material is prepared from the following raw materials in parts by weight: 37-53 parts of polybutylene terephthalate, 24-38 parts of polyarylene ether ether nitrile, 4-8 parts of triglycidyl isocyanurate, 3-6 parts of diphenylmethyene bismaleimide, 2.5-4.5 parts of zinc tetroxy chromate, 16-22 parts of wollastonite powder, 2-4 parts of triethoxyisobutylsilane, 4-6 parts of ethyl-3-amino crotonic acid ester, 12-18 parts of dioctyl terephthalate, 2-3 parts of p-tert-butylcatechol, 5-10 parts of melamine cyanurate, 3-6 parts of diphenyl silanediol, 10-15 parts of phenol-aralkyl epoxy resin, 1.5-2.5 parts of 2-ethyl acetate lead, 4-8 parts of lignite wax and 5-10 parts of diisobutyl aluminum hypophosphite. The jacket material disclosed by the invention has excellent heat resistance, and also has extremely excellent water resistance; and meanwhile, the jacket material has excellent properties such as chemical corrosion resistance, aging resistance, wear resistance, environmental stress cracking resistance and the like, and can be used in the hot and humid areas for a long time.

Description

technical field [0001] The invention relates to a communication optical cable sheath material for hot and humid areas and a preparation method thereof, belonging to the field of optical cable sheath materials. Background technique [0002] The communication optical cable is composed of a cable core and an outer sheath composed of several (core) optical fibers (generally from several cores to several thousand cores), and has a much larger transmission capacity; less attenuation; long transmission distance; small size; weight Lightweight; no electromagnetic interference; low cost, it is currently the most promising communication transmission medium, widely used in signal transmission in various departments such as telecommunications, electric power, and broadcasting, and will gradually become the main body of future communication networks. Due to the limitations of the laying or use environment, the communication optical cable needs to be protected by an outer protective layer...
