Problems solved by technology

[0003] Although the existing anti-rodent cable material technology has been used in various cable reports, what the prior art adopts are polyethylene or polyvinyl chloride or polyolefin resin or polyolefin elastomer and other materials as basic materials, resulting in the material being damaged at room temperature. The soft performance, weather resistance, elasticity, flame retardancy and oil resistance of the cable are poor, and cannot meet the requirements of existing customers for cable performance. 3. The cable provided by the Chinese invention. In addition, in the prior art including the application number CN200610028832.X, the anti-rodent agent used in the cable is mainly a repellant or a repellent, and the main component is dimethylcyclopropane carboxylic acid Esters and substances such as vanillyl nonanoic acid amine or fluthrin, which are different from the synthetic capsaicin used in the present invention

Embodiment 1

[0061] Raw materials are prepared according to the proportioning of Table 2 Example 1, and the anti-rat cable rubber sheath material is prepared as follows:

[0062] First take the basic rubber polychloroprene that has been masticated, knead it on a small open mill, and then add stabilizer light magnesium oxide, anti-aging agent TPPD and ODA, filler light calcium carbonate, reinforcing filler Agent white carbon black, gas-mixed carbon black and calcined clay, anti-rodent agent synthetic capsaicin, operating agent paraffin and vaseline, anti-scorch agent TMTD and DM, silane coupling agent KH-550, vulcanizing agent active zinc oxide and vulcanization accelerator For HVA-2 and NA-22, when the mixing temperature is lower than 40°C, the rubber material is obtained by mixing and molding, and the distance between the rollers of the small open mill is reduced, and the rubber material is thinly sliced, that is, the rubber is triangular bagged for 3 times, and then the sheet is produced....

Embodiment 2

[0065] Raw materials are prepared according to the proportioning of Table 2 Example 2, and the anti-rat cable rubber sheath material is prepared as follows:

[0066] Put the basic rubber polychloroprene that has been masticated first into the internal mixer, the mixing temperature is lower than 40°C, and knead for about 30 seconds, then add anti-aging agents TPPD and ODA, stabilizers light magnesium oxide, anti-scorch Agent TMTD and DM, operating agent paraffin and vaseline, filler light calcium carbonate, reinforcing filler silica, aerated carbon black and calcined clay, rodent control agent synthetic capsaicin and silane coupling agent KH-550, mixed After smelting for about 3 minutes, add the vulcanizing agent system composed of active zinc oxide, HVA-2 and NA-22, and knead for about 25 seconds, then discharge, compress, and open strips, and then cool the sheets for later use. The thickness of the rubber sheet is about 2mm, and the width is 250mm. It is used after parking fo...

Embodiment 3

[0069] Raw materials are prepared according to the proportioning of table 2 embodiment 3, and the anti-rat cable rubber sheath material is prepared as follows:

[0070] Put the basic rubber polychloroprene that has been masticated first into the internal mixer, the mixing temperature is lower than 40°C, and knead for about 1 minute, then add anti-aging agent TPPD and ODA, stabilizer light magnesium oxide, anti-scorch Agent TMTD and DM, operating agent paraffin and vaseline, filler light calcium carbonate, reinforcing filler silica, aerated carbon black and calcined clay, rodent control agent synthetic capsaicin, silane coupling agent KH-550, mixed After smelting for about 5 minutes, add the vulcanizing agent system composed of active zinc oxide, HVA-2 and NA-22, and knead for about 35 seconds, then discharge, compress, and open strips, and then cool the sheets for later use. The thickness of the rubber sheet is about 2mm, and the width is 250mm. It is used after parking for at...

Abstract

The invention belongs to the manufacturing field of cables, particularly relates to a ratproof cable rubber sheath material which is mainly prepared from the following raw materials in part by weight: 100 parts of polychloroprene, 5 parts of zinc oxide, 1.5-3 parts of vulcanization accelerator, 0.75-1.5 parts of scorch retarder, 3.5-5 parts of antiager, 4 parts of magnesium oxide, 30-60 parts ofcalcium carbonate, 30-50 parts of reinforcing filler, 1.5-2.5 parts of silane coupling agent, 5-10 parts of operating agent and 2.5-7.5 parts of synthetic capsaicin. The ratproof cable rubber sheath material provided by the invention has the characteristics of better flexibility, oil resistance, weather resistance, inflaming retarding and the like, and not only meets the requirements of field andusers on rubber cable rat bite prevention, but also brings convenience for the users.

Description

technical field [0001] The invention belongs to the field of cable manufacturing, and in particular relates to a cable sheath material which is especially suitable for high requirements for preventing rodents from biting, and a preparation method and application thereof. Background technique [0002] Rats in wild or human-inhabited areas have a strong ability to damage wire and cable sheaths or insulation layers. It is often reported that voles gnaw on the cables laid in the field and cause the cable to fail, and the situation that the wires in urban houses are gnawed by mice also occurs from time to time, so the rodent-proof functional plastic or cross-linked plastic cable material came into being. The production of cables from materials can better solve the problem of rodent gnawing. However, the anti-rodent material configured with plastic or cross-linked plastic as the basic material is used on the cable. The cable is hard and has poor bending performance, so it cannot b...
