Special material for protective casing for preventing pests and rats from biting communication cable and preparation method of special material

Abstract

The invention discloses a special material for a protective casing for preventing pests and rats from biting a communication cable and a preparation method of the special material. The special material is prepared from the following raw materials in parts by weight: 52-76 parts of polypropylene, 31-43 parts of ethylene-trifluorochlor oethylene copolymer, 3-6 parts of benzyl benzoate, 4-6 parts of diethylene glycol bis(allylcarbonate), 2-4 parts of cycloheximide, 3-5 parts of tetrabasic lead sulfate, 10-15 parts of dicyclohexyl phthalate, 16-22 parts of spherical silica sand, 2-4 parts of triphenyltin acetate, 1.5-2.5 parts of m-chloroaniline, 5-10 parts of dibutyl azelate, 2-3 parts of phenyl diisodecyl phosphate, 4-8 parts of chlorinated paraffin, 8-14 parts of barium metatitanate, 5-10 parts of encapsulated red phosphorous, 1-2 parts of phenylethyl resorcinol and 4.5-6.5 parts of an adjuvant. The substances such as benzyl benzoate, triphenyltin acetate and m-chloroaniline are added to the special material for the protective casing disclosed by the invention, so that the pest and rat bite preventing property of the protective casing can be greatly improved; the damage to the protective casing caused by pests and rats is effectively prevented; the safety and normal operation of an optical cable are ensured; and meanwhile, the special material has excellent abrasive resistance, weather fastness, corrosion resistance and temperature tolerance, long service life and wide application range.

Description

technical field [0001] The invention relates to a special material for preventing insects and rats from biting communication cable sheath tubes 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 protecte...

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 insect and rat bite performance, and are easily bitten by rats and insects, resulting in damage to the sheath tube, which seriously affects the transmission of optical fibers.
