Abstract
The invention discloses a flame-retardant type ethylene propylene rubber cable material. The flame-retardant type ethylene propylene rubber cable material comprises the following materials in parts by weight: 100-110 parts of LANXESS 3950 ethylene-propylene-diene rubber, 3-5 parts of triethylene glycol diisooctoate, 18-20 parts of barium sulfate powder, 10-15 parts of hydrotalcite powder, 3-4 parts of antimonous oxide, 3-4 parts of sodium dihydrogen phosphate, 4-6 parts of chlorinated paraffin, 6-10 parts of nylon acid di-n-butyl ester, 1-2 parts of anti-ageing agent DFC (Dense Fiber Component)-34, 1-2 parts of 2-thiol-based benzimidazole, 3-4 parts of aluminum hydroxide, 1-2 parts of vinyl tri(beta-methoxyl ethyoxyl) silicane, 0.8-1 part of vulcanizing agent DCBP (Dichloro Benzoyl Peroxide), 1-2 parts of dodecyl dimethyl betaine, 2-3 parts of accelerant PZ and 25-30 parts of performance additives. The cable material provided by the invention has the advantages of excellent physical performances, stable dimension, low shrinkage rate, strong stress at definite elongation, strong hardness and strong abrasion resistance, good high and low temperature resistance, good oil resistance, good heat resistance, good ozone resistance and good ageing resistance. Moreover, the cable material disclosed by the invention is very strong in flame resistance, is particularly applicable to various high-temperature environments, and is safe and reliable.
Description
technical field [0001] The invention mainly relates to a cable material, in particular to a flame-retardant ethylene-propylene rubber cable material. Background technique [0002] Ethylene-propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil-filled properties and fluidity at room temperature. 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 antioxidants can increase its service temperature. EPDM rubber cross-linked 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 unsaturation of ethylene-propylene rubber, it has good resistance to various polar chemicals su...
