Mouldproof special material for communication optical fiber cable jacket and preparation method thereof

Abstract

The invention discloses a mouldproof special material for a communication optical fiber cable jacket and a preparation method thereof. The mouldproof special material is prepared from the following raw materials in parts by weight: 42-64 parts of polyphenyl ether, 28-44 parts of a styrene-butadiene-styrene triblock copolymer, 4-7 parts of diazolidinyl urea, 3-5 parts of para-hydroxybenzoate chitosan ester, 2-4 parts of o-phenylphenol, 10-15 parts of light roasting powder, 8-14 parts of epoxidized methyl acetorieinoleate, 10-15 parts of sienna stone powder, 1-2 parts of allylthiourea, 4-6 parts of alurninium hydroxydistearate, 5-10 parts of dioctyl isophthalate, 12-16 parts of cryolite powder, 4-8 parts of butyl epoxystearate, 5-10 parts of liquid paraffin, 6-12 parts of magnesium hydroxide, 4-8 parts of zinc borate, 1-2 parts of nickel dibutyl dithiocarbamate, 2-3 parts of propyl gallate and 3-5 parts of auxiliaries. The special material for the jacket disclosed by the invention is good in mouldproof property, wear resistance and corrosion resistance, can be used for a long time in a humid environment, can be used for effectively inhibiting propagation of moulds and has excellent dimensional stability, remarkable propagate, relatively high tensile strength and relatively good creep resistance, wear resistance and temperature resistance.

Description

technical field [0001] The invention relates to a special material for an anti-mold 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 protec...

AI Technical Summary

Problems solved by technology

At present, the materials used for the sheath tube of communication optical cables in the market have the disadvantage of poor anti-mold, and mold is easy to grow in a humid environment, thereby corroding the sheath tube and affecting the normal transportation of the optical cable.
