Special material for ultraviolet resistant communication optical cable protective casing and preparation method of special material

Abstract

The invention discloses a special material for an ultraviolet resistant communication optical cable protective casing and a preparation method of the special material. The special material is prepared from the following raw materials in parts by weight: 56-74 parts of bisphenol A polycarbonate, 1-2 parts of 2,2',4,4'- tetrahydroxyl benzophenone, 5-8 parts of shea butter, 9-16 parts of zinc dihydrogen phosphate, 24-38 parts of acrylonitrile-butadiene-styrene terpolymer, 4-8 parts of pentachloro methyl stearate, 2-3 parts of neodymium iso-octanate, 10-15 parts of titanium dioxide, 18-26 parts of copolymer of 1,1,2,3,3,3-hexafluoro-1-propylene, 1,1-polyvinylidene floride and tetrafluoroethylene, 2-4 parts of tri(thioglycollic acid n-butyl ester) antimony, 3-6 parts of behenamide, 15-20 parts of organobentonite, 6-12 parts of dimethyl methylphosphonate, 5-10 parts of ammonium tetramolybdate, 2-3 parts of hydroquinone monomethyl ether, 1.5-2.5 parts of 2-phenyl benzimidazole-5-sulfonic acid and 3-6 parts of aids. The special material for the protective casing has excellent ultraviolet resistance, aging resistance, solar irradiation resistance, excellent mechanical property and electrical insulation property and high wear resistance, heat resistance and corrosion resistance, the optical cable protective casing can be kept from fading for a long time under sunshine and is prevented from being aged and cracked, and the service life of the protective casing is prolonged.

Description

technical field [0001] The invention relates to a special material for an anti-ultraviolet communication optical cable sheath tube 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 ranging from several cores to thousands of 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...

AI Technical Summary

Problems solved by technology

At present, the materials used for communication optical cable sheath tubes in the market have the disadvantage of poor UV resistance, and are prone to aging and cracking after long-term exposure to sunlight, which seriously affects the transmission of optical fibers.
