Background

Along with the application of mixed cable of photoelectricity, the mechanical properties of mixed cable of photoelectricity, prevention of seepage water function and anti-oxidant function receive people's attention, simultaneously, the rodent has constantly to grind the tooth and indiscriminate the habit of stinging the object, when adopting plastics such as polyolefin as the sheath material of mixed cable of photoelectricity, can receive the rodent to sting in laying the environment and destroy, the little hole can appear in the mixed cable of destroyed photoelectricity, when weing or soaking the back, can arouse the electric leakage short circuit, even cause accidents such as explosion. Therefore, the rat-proof problem of the optical-electric hybrid cable is attracting more and more attention.

At present, the rat-proof method of the cable mainly comprises two methods:

1. physical protection method: the ratproof effect is achieved by improving the hardness, toughness and surface smoothness of the material [ Cao Bing, Chinese patent ZL02212768.2 ]. Typical non-metallic materials are nylon and nylon-like materials in addition to metallic materials. Nylon has high hardness, good toughness and surface smoothness, and good ant and rat prevention effects [ Ding Zhi faithful, aged soldiers, Gao Jia Rui, Chinese patent ZL 200610039150.9; huqing, von yu, chinese patent, ZL200520073392.0], however, in the processing process, secondary extrusion is required, i.e. a layer is extruded outside the optical cable sheath, the process is complex, the price is high, the production cost is high, and the application in practical production is less. The common polyolefin cable sheath material has low cost, but the material has low hardness, so that a physical protection method is difficult to realize.

2. Chemical protection method: namely, a certain amount of repellent or repellent is added into the material to achieve the effect of rat prevention. The commonly used repellents include chlordane, lindane, heptachlor, aldrin, dieldrin, etc., which are harmful to human body, have carcinogenic effect and are harmful to environment, so the repellents are prohibited to use. Some repellents with medium or low toxicity, high efficacy, long half-life are currently selected, such as 2-isopropylphenyl-N-methylcarbamate, α -cyano-3-phenoxybenzyl-d-cis-2, 2-dimethyl-3- (2 ', 2' -dibromoethenyl) cyclopropanecarboxylate, diphenolylpropane, vanillylnonanamide or cycloheximide [ zhou baomao, jumatsuntan, chinese patent, ZL 99113759.0; xuyongwei, moohou bin, xiaomingyu, etc., chinese patent ZL 200610119415.6. However, the addition of repellents causes a reduction in the mechanical properties of the material while still being polluting to the environment.
