Abstract

The invention discloses a wear-resistant, anti-oxidation and anti-seepage photoelectric hybrid cable. The cable comprises an outer protection layer, a hybrid cable core and a ratproof layer. The outer protective layer is prepared from the following components in parts by weight: 18 to 21 parts of linear low-density polyethylene, 3.1 to 4.6 parts of chlorinated paraffin-52, 1.3 to 2.2 parts of polyether modified silicone oil, 6 to 9 parts of barium sulfate, 3 to 6 parts of high-abrasion-resistance carbon black, 1 to 3 parts of 2, 6-di-tert-butyl-4-methylphenol and 4 to 5 parts of calcium carbonate. The ratproof layer is prepared from the following components in parts by weight: 5 to 7 parts of barium sulfate, 6 to 9 parts of diphenoxylate, 5 to 10 parts of phthalate, 3 to 5 parts of polyvinyl alcohol, 1.8 to 2.3 parts of mint extract, 10 to 13 parts of capsaicin and 4 to 6 parts of ethanol. The photoelectric hybrid cable prepared from the raw materials is good in mechanical properties, long in service life and capable of effectively preventing rats.

Description

technical field [0001] The invention relates to the technical field of functional polymer materials, in particular to a wear-resistant, oxidation-resistant, water-proof photoelectric hybrid cable. Background technique [0002] With the application of photoelectric hybrid cables, the mechanical properties, water-proof function and anti-oxidation function of photoelectric hybrid cables have attracted people's attention. At the same time, rodents have the habit of constantly grinding their teeth and biting objects randomly. The sheath material of the optical-electrical hybrid cable will be damaged by rodents in the laying environment, and the damaged optical-electrical hybrid cable will have small holes. When it is damp or soaked in water, it will cause leakage and short circuit, and even cause explosions and other accidents. Therefore, the anti-rat problem of optical-electrical hybrid cables has attracted more and more attention. [0003] At present, there are two main ways t...
