Abstract
The invention discloses a cable sheathing material with an antimycotic function. The cable sheathing material consists of the following materials in parts by weight: 104-110 parts of ethylene-propylene-diene monomer K520, 10-20 parts of carbon black N660, 7-10 parts of hexagonal boron nitride, 2-3 parts of decabromodiphenylethane, 10-15 parts of wollastonite powder, 4-5 parts of polyethylene wax, 1-2 parts of lithium carbonate, 1-2 parts of copper oxide, 4-5 parts of diallyl phthalate, 4-6 parts of zinc stearate, 1-2 parts of an anti-ageing agent ODA (Octyl Decyl Adipate), 1-2 parts of tributyl tin chloride, 1-2 parts of 2-(3,4-epxoy cyclohexyl) ethyl trimethoxy silane, 0.8-1 part of a vulcanizing agent DCBP (Dichlorobenzoyl Peroxide), 1-2 parts of accelerant TMTD (Tetramethyl Thiuram Disulfide) and 15-30 parts of modifying auxiliaries. A cable material produced by the cable sheathing material can be used for effectively restraining growth, formation and reproduction of mycete, so that a cable is free from infringement of mycete; reduction of the service life of the cable and loss of the power supply bureau due to the reason that the cable is forced to change because of mycete growth are avoided, thereby prolonging the service life of an electric wire cable. The cable material provided by the invention has good physical performance, heat resistance, stretching resistance, strong tear resistance and good comprehensive performance.
Description
technical field [0001] The invention mainly relates to a cable material, in particular to a cable sheath material with anti-mold function. Background technique [0002] Ethylene-propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color, electrical properties, oil filling and room temperature fluidity. Ethylene-propylene rubber products can be used for a long time at 120°C, and can be used temporarily or intermittently at 150-200°C. Adding suitable anti-aging agent can increase its service temperature. EPDM rubber crosslinked with peroxide can be used under more severe conditions. Under the conditions of ozone concentration of 50pphm and stretching of 30%, EPDM rubber can reach more than 150h without cracking. [0003] Due to the lack of polarity and low degree of unsaturation of ethylene-propylene rubber, it has good resistance to various polar chemicals such as alcohols, acids, alkalis,...
