Problems solved by technology

[0004] In order to prolong the service life of the optical cable, an optical cable sheath will be installed outside the optical cable. The existing optical cable sheath only protects the optical cable from temperature and acid and alkali corrosion, but does not have the effect of preventing woodpeckers from breaking the optical cable.

Abstract

The invention discloses an anti-woodpecker optical cable sheathing material and a preparation method thereof. The anti-woodpecker optical cable sheathing material is prepared from the following raw materials in parts by weight: 1.6-2.5 parts of realgar, 8-11.5 parts of endive, 26-33 parts of polytetrafluoroethylene, 48-62 parts of polybutylene terephthalate, 9-13.6 parts of flax fiber, 8-11.2 parts of graphite powder, 17.5-22.6 parts of shell powder, 5.5-7.2 parts of fructo-oligosaccharide, 6-8.8 parts of flame retardant, and 10-14.5 parts of crosslinking agent. Different materials are prepared into different products through different preparation processes; different products cooperate with each other and can play synergies, so that the prepared finished product gives out smell that birdsand rats do not like with long duration, thereby preventing rats and birds from eating. The product prepared by the invention has good tensile strength, breaking elongation and flame resistance.

Description

technical field [0001] The invention relates to an optical cable, in particular to a woodpecker-proof optical cable sheath material. Background technique [0002] With the development of science and technology, the communication between people is more and more frequent, and the communication industry has also been greatly developed. Communication is the exchange and transmission of information between people or between people and nature through a certain behavior or medium. In a broad sense, it refers to the two or more parties who need information no matter what method they use and what information they use without violating their respective wishes. A medium that accurately and securely transmits information from one party to another. [0003] Optical cable is a commonly used facility in the communication industry. Optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a sheath as ...
