Tetrafluoroethylene-hexafluoropropylene copolymer communication optical cable protective jacket material and preparation method thereof

Abstract

The invention discloses a tetrafluoroethylene-hexafluoropropylene copolymer communication optical cable protective jacket material and a preparation method thereof. The tetrafluoroethylene-hexafluoropropylene copolymer communication optical cable protective jacket material is prepared from the following raw materials in part by weight: 68 to 82 parts of tetrafluoroethylene-hexafluoropropylene copolymer, 36 to 54 parts of vinyl chloride-ethylene-butyl acrylate copolymer, 18 to 32 parts of reworked material, 3 to 6 parts of oleoyl diethanol amine, 10 to 15 parts of polypentabromobenzyl acrylate, 1 to 2 parts of nickel dibutyl dithiocarbamate, 12 to 16 parts of condensed phosphoric acid, 16 to 22 parts of acetyl tributyl citrate, 2 to 3 parts of 4,4-bis(phenylisopropyl)diphenylamine, 4 to 8 parts of bisphenol A alkyl phosphate, 10 to 15 parts of amorphous graphite powder, 2 to 4 parts of zinc laurate, 3 to 5 parts of behenamide, 10 to 15 parts of calcined andalusite powder and 1 to 2 parts of 4-tert-butylcatechol. The protective jacket disclosed by the invention has excellent comprehensive performance, excellent electrical insulation property and mechanical property, excellent heat resistance, chemical stability, creep resistance and aging resistance, a long service life, a wide application range and wide market prospect.

Description

technical field [0001] The invention relates to a polyperfluoroethylene propylene communication optical cable sheath material 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 protecti...

AI Technical Summary

Problems solved by technology

At present, the sheath materials used for communication optical cables in the market have poor comprehensive performance, and have the disadvantages of heat resistance, aging resistance and poor chemical stability, which limit their application range and shorten their service life.
