Abstract
A low-temperature-resistant, oil-resistant, flame-retardant and environmentally friendly CPE rubber sheath material, comprising the following raw materials in parts by weight: 40-50 parts by weight of CPE resin, 3-6 parts of plasticizer, 14-20 parts of reinforcing agent, 10-20 parts of filler calcium carbonate, Talc powder 15~20, environmental stabilizer 2~4, hydrogen chloride absorbent 2~3, lubricant 2~5, flame retardant 4~8, vulcanizing agent 1.5~2, co-vulcanizing agent 1.5~2. The environmental protection CPE rubber sheath material of low temperature resistance and oil resistance group prepared according to the present invention can replace the rubber sheath material containing heavy metals, polybrominated biphenyls and ethers, etc. , significant social benefits, will not cause pollution to the environment; can be used for power cables and mine cables, marine cables, electrical equipment lines, etc., so that the low temperature resistance, oil resistance and flame retardancy of cables and wires are greatly improved compared with the rubber commonly used today.
Description
technical field [0001] The invention relates to a low-temperature-resistant, oil-resistant, flame-retardant and environment-friendly CPE rubber sheath material and a preparation method thereof. Background technique [0002] Traditional CPE rubber wire and cable sheathing materials contain (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr) heavy metal elements, polybrominated biphenyls and their ethers and other harmful substances that are contrary to environmental protection requirements and affect human beings. Health and ecological environment, and low temperature resistance, oil resistance and flame retardancy cannot meet the requirements. [0003] The power cord of household appliances requires very good flexibility, otherwise the sheath of the power cord will be broken during frequent use; many wires and cables are used in very low temperature environments, if the low temperature performance of the cable sheath material cannot If the requirements are met, the s...
