Low temperature resistant high elasticity chlorinated polyethylene power line jacket material as well as preparation method thereof

Abstract

The invention discloses a low temperature resistant high elasticity chlorinated polyethylene power line jacket material as well as a preparation method thereof. The low temperature resistant high elasticity chlorinated polyethylene power line jacket material is prepared from the following substances in parts by weight: 70-90 parts of chlorinated polyethylene, 20-30 parts of an ethylene-vinyl acetate copolymer, 10-15 parts of a thermoplastic polyurethane elastomer, 0.4-0.8 part of bis(tert-butyldioxyisopropyl)benzene, 1.5-2.5 parts of triallyl isocyanurate, 4-8 parts of molybdenum disulfide, 10-15 parts of antimonous oxide, 8-12 parts of silicon micropowder, 5-10 parts of polytetrafluoroethylene micropowder, 10-15 parts of dioctyl nylon acid, 3-5 parts of sorbitol, 5-10 parts of dioctyl sebacate, 20-25 parts of precipitated white carbon black, 2-3 parts of a flexibilizer TMTD (Tetramethyl Thiuram Disulfide), 1-2 parts of an anti-aging agent ODA [bis(4-octylphenyl)amine], 1-2 parts of an anti-aging agent TPPD [N-(p-toluene-sulphonylamido-N'-phenylenediamine)] and 3-5 parts of composite filler, wherein the accelerant has low temperature resistance and high elasticity, so that the jacket material still maintains good elasticity under a condition of a low temperature of -50 DEG C. The jacket provided by the invention is tough, has excellent physical and mechanical performances, electric insulating performance, anti-aging resistance, wear resistance and impact resistance, and is durable, safe and reliable and wide in application prospect.

Description

technical field [0001] The invention relates to a power cord sheathing material and a preparation method thereof, in particular to a low-temperature-resistant high-elasticity chlorinated polyethylene power cord sheathing material and a preparation method thereof. Background technique [0002] The power cord sheath is an indispensable intermediate structural part of the power cord, which protects the power cord, ensures the safety of the power cord, and isolates the copper wire from water, air and other media to avoid leakage. Chlorinated polyethylene sheath material is suitable for power cord sheath due to its excellent flame retardancy, weather resistance and good physical and mechanical properties, and has sufficient protection for copper cores. However, the low temperature resistance and elasticity of the existing chlorinated polyethylene power cord sheath are difficult to meet the requirements of use at the same time, so it is urgent to develop a chlorinated polyethylene...
