Wear-resistant irradiation cross-linked polyvinyl chloride (PVC) insulating material for automotive original line and preparation method thereof

Abstract

The invention discloses a wear-resistant irradiation cross-linked polyvinyl chloride (PVC) insulating material for an automotive original line and a preparation method thereof. The wear-resistant irradiation cross-linked polyvinyl chloride insulating material for the automotive original line comprises the following components in part by weight: 40-60 parts of PVC resin powder with a molecular weight of 1300, 25-50 parts of chlorinated polyethylene material, 5-15 parts of a PVC modifier, 5-15 parts of a PVC non-toxic plasticizer and stabilizer, 30-70 parts of trimellitic acid ester 380, 5-10 parts of a calcium / zinc compound stabilizer, 15-50 parts of nano calcium carbonate, 0.2-1.5 parts of an antioxidant, 5-15 parts of a sensitizer, 0.1-0.6 part of an alcohol ester type compound lubricant and 0-1 part of impurities incapable of changing the component property. The wear-resistant irradiation cross-linked polyvinyl chloride (PVC) insulating material and the preparation method thereof have the benefits that the problem that a large square conductor cable cannot pass at a low temperature is solved, the problem that a small square conductor cable cannot pass after being scraped and abraded is also solved, the problem of narrow irradiation dose range during irradiation crosslinking is also solved, and the risk of disqualification after irradiation crosslinking is reduced.

Description

technical field [0001] The invention relates to an insulating material for automobile primary wires and a preparation method thereof, in particular to a wear-resistant irradiation cross-linked polyvinyl chloride insulating material for automobile primary wires and a preparation method thereof. Background technique [0002] The insulation material used for the original wire of the car needs to be resistant to high temperature and prevent natural environment, especially in summer. At the same time, it must be resistant to low temperature and prevent freezing, especially in winter. When the insulation material used for traditional automobile original wires is made into a small square cable, the scraping test generally cannot pass, so it can only be made into a large square cable, which costs some materials and thus increases the cost, but the low temperature test of the large square conductor cable It is not easy to pass, and it takes a lot of cost to overcome. Another techni...
