Abstract

The invention discloses a rat-bite-preventing cable sheath material. The rat-bite-preventing cable sheath material is prepared from raw materials in parts by weight as follows: 60-80 parts of nitrile silicone rubber, 15-25 parts of butyl rubber, 30-40 parts of chlorosulfonated polyethylene, 1.5-2.5 parts of 1,1-di-(tert-butylperoxy)cyclohexane, 2-3 parts of sodium ammonium dichromate, 115-125 parts of a filling reinforcing agent, 3-6 parts of epoxidized soybean oil, 2-4 parts of dioctyl phthalate, 4-6 parts of stearic acid and 2.5-4 parts of an anti-aging agent, wherein the filling reinforcing agent is prepared from components in parts by weight as follows: 15-20 parts of a starch complex, 30-40 parts of hard pottery clay, 20-30 parts of silk fibers, 8-16 parts of diatomite and 25-35 parts of fumed silica. The rat-bite-preventing cable sheath material has excellent rat-proof performance, prevents a cable from being bitten and damaged by rats, and is quite good in tensile strength and wear resistance and low in cost.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a rodent-proof cable sheath material. Background technique [0002] It is extremely important for the cable to transmit electric energy normally under the condition of special changes in the occasions that require high tensile strength and wear resistance. As a rodent with strong reproduction and vitality, mice live widely. In various regions of the world, because the incisors are well developed and grow continuously, rodents have the habit of biting objects to keep their teeth sharp. The unique smell of rubber materials used for cable sheaths makes plastics a common object for rodents to bite. It is often reported that voles gnaw on the cables laid in the field and cause the cables to fail. This requires extremely high tensile strength and wear resistance of the cables, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems...
