Environment-friendly high-and low-temperature resistant oil-resistant polyvinyl chloride cable sheathing compound

Abstract

An environment-friendly high-and low-temperature resistant oil-resistant polyvinyl chloride cable sheathing compound is composed of the following raw materials (by weight): 100 parts of polyvinyl chloride resin, 50-70 parts of a trimellitate plasticizer, 4-12 parts of a Ca-Zn composite stabilizer, 10-35 parts of a filler, 10-35 parts of copolymer resin, 15-35 parts of thermoplastic elastomer resin, 5-10 parts of diantimony trioxide, a flame retardant synergist being less than or equal to 6 parts, 0.4-2.0 parts of an antioxidant, and 0.3-2.8 parts of an ultraviolet absorber. The product has excellent low temperature resistance, heat resistance, oil resistance, weather resistance and the like. Toughness, low temperature resistance and oil resistance of the product are enhanced. The product has properties such as heat resistance, oil resistance, elasticity, flexibility, chemical resistance and the like. The product is endowed with heat resistance, weatherability and other comprehensive properties. Low cost of the sheathing material for cables of charging piles is realized.

Description

technical field [0001] The invention belongs to the technical field of polymer materials for electric wires and cables, and in particular relates to an environment-friendly high-temperature and low-temperature oil-resistant polyvinyl chloride cable sheathing material. Background technique [0002] In the face of increasingly serious energy, climate and environmental problems, the development of new energy vehicles has become a global consensus, and new energy electric vehicles have gradually become popular all over the world. The car charging pile cable is one of the key equipment of the electric vehicle conductive charging system that connects the electric vehicle to the power supply. Due to the location of the cable, it may be affected by unfavorable environments including sunlight, weathering, humidity, oil pollution, etc., and it is often used during use. Suffering damages such as bending, dragging, friction, etc. Therefore, the performance of the cable will have a direc...

Problems solved by technology

Another example is that the aforementioned CN105504593A adds traditional chlorinated butylene or nitrile rubber or its mixture to the formula to achieve high and low temperature resistance, abrasion resistance and oil resistance. difficult problem, then its processing technology is quite complicated

[0006] In short, because the oil-resistant and temperature-resistant PVC cable materials in the prior art have not been reasonably balanced or comprehensively considered in terms of low-temperature resistance, oil resistance, heat resistance, and abrasion resistance, the cables made of them It is difficult to meet the needs of normal use, and the material processing technology is complicated, which increases the cost of materials and is not conducive to saving energy
