Abstract

The invention discloses a high-weatherability chlorinated polyethylene power cord sheath material and a preparation method thereof. The high-weatherability chlorinated polyethylene power cord sheath material is prepared from the following substances in parts by weight: 70-90 parts of chlorosulfonated polyethylene rubber, 20-30 parts of ethylene-propylene-diene monomer rubber, 10-15 parts of SEBS (styrene-ethylene / butylene-styrene), 3-5 parts of high-activity magnesium oxide, 2-4 parts of microcrystalline wax, 15-20 parts of talcum powder, 20-30 parts of carbon black N550, 5-10 parts of black bacon rubber, 2-3 parts of triallyl isocyanurate, 0.5-1 part of 1, 3-bis(t-butylperoxy isopropyl) benzene, 10-15 parts of trioctyl trimellitate, 8-12 parts of dioctyl phthalate, 1-2 parts of antioxidant 168 and the like. The sheath material disclosed by the invention has excellent weatherability and anti-aging property, can be used in an environment with the temperature from -50 DEG C to 105 DEG C for a long time without deforming or cracking, has excellent electrical insulation, tensile strength, oil resistance, resistance to acid and alkali corrosion, environmental friendliness, and flame retardancy, is durable, safe and reliable, and has a broad market prospects.

Description

technical field [0001] The invention relates to a power cord sheathing material and a preparation method thereof, in particular to a highly weather-resistant 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. However, the existing power cord sheaths have the disadvantage of poor weathering resistance, long-term exposure to the outdoors, and are prone to deformation, cracking, etc., thereby affecting the normal and safe operation of the power cord. Contents of the invention [0003] The object of the present invention is to provide a high weather-resistant chlorinated polyethylene power cord sheath material and a preparation method thereof, so as to improve the weather agin...
