Abstract

The invention discloses an oil-resistant level PVC (Poly Vinyl Chloride) sheath material for a power wire and a preparation method thereof. The oil-resistant level PVC sheath material is prepared from the following substances in parts by weight: 65-75 parts of polyvinyl chloride resin, 25-35 parts of nitrile rubber, 20-30 parts of carbon black N660, 10-15 parts of dioctyl maleate, 3-6 parts of light magnesium oxide, 2-4 parts of zinc oxide, 2-3 parts of dibenzothiazyl disulfide, 1-2 parts of tetrasulfide dipentylidene thiuram, 0.4-0.6 parts of 1,4-bistertiary butyl peroxy isopropyl benzene, 1.5-2.5 parts of triallyl isocyanuric acid ester, 0.5-1 part of insoluble sulfur, 4-8 parts of coumarone resin, 1-3 parts of stearic acid, 2-3 parts of palm wax, 1-2 parts of 2-thiol benzothiazole, 0.5-1.5 parts of methyl tin mercaptide, 10-15 parts of nano wollastonite, 5-10 parts of organic bentonite and 3-6 parts of composite filler. The sheath material is excellent in corrosion property of oil-resistant product organic solvents, maintains good flexibility, softness and mechanical strength after being immersed by oleophylic product organic solvents, is non-deformable and non-cracking in long-term use, and is long in service life.

Description

technical field [0001] The invention relates to a power cord sheathing material and a preparation method thereof, in particular to an oil-resistant PVC sheathing material for a power cord 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. Existing power cord sheaths are mostly made of PVC materials. Although the PVC sheath has good flexibility, its oil resistance is poor, and it is easily corroded by oil products, which will cause cracks in the power cord and affect the quality of the power cord. performance. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, provide an oil-resistant PVC sheath material for power cords and a preparation method thereof, impr...
