Polyvinyl chloride elastomer cable material for charging pile cables and preparation method thereof

Abstract

The invention discloses a polyvinyl chloride elastomer cable material for charging pile cables. The polyvinyl chloride elastomer cable material comprises the following components by weight: charging cable with PVC elastomer cable material, by weight comprises the following components: 100 parts of polyvinyl chloride resin matrix, 10-20 parts of a matte texture modifier, 50-90 parts of a plasticizer, 5-15 parts of a super cold-resistant modifier, 5-15 parts of an oil-proof modifier, 12-18 parts of a super heat-resistant stabilizer, 0.4-0.6 part of an oxidant, 0.2-0.4 part of a light stabilizer, 0.2-0.4 part of a lubricant, 0.5-2 parts of a processing aid, 20-40 parts of inorganic filler, and 4-16 parts of a flame retardant. The polyvinyl chloride resin matrix is composed of 0-70 parts of polyvinyl chloride resin with ultra-high molecular weight and 30-100 parts of gel polyvinyl chloride resin. The polyvinyl chloride elastomer cable material for charging pile cables provided by the invention has the characteristics of high tensile strength, high tear strength, a heat resistant grade up to 125DEG C, a cold-resistant grade of -50DEG C, good aging resistance, good resistance to gasoline and machine oil, a flame retardant level up to VW-1 for V0 level flame retardant cable, low VOC, and high-grade surface matte texture, etc.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a polyvinyl chloride elastomer cable material for charging pile cables and a preparation method thereof. Background technique [0002] With the gradual depletion of energy and the deterioration of the environment, vigorously developing new energy has become an important strategic goal of countries around the world. In recent years, electric vehicle technology has become the focus of the automotive industry to deal with environmental pollution and alleviate the energy crisis. Various countries and major automakers around the world have invested huge sums of money in the development of electric vehicles. Compared with traditional cars, electric vehicles have the advantages of low energy consumption, low noise, zero emissions and no pollution, and have become an industry that the Chinese government pays close attention to and strongly supports. At the same time, the constru...

Problems solved by technology

This material has excellent heat resistance and oil resistance, but its cold resistance is not enough, it is difficult to meet the use requirements of -50°C, and the polyvinyl chloride resin selected for this material is an ordinary polyvinyl chloride resin without gel components, which does not have a matte finish. High-grade appearance, and its heat resistance and elasticity are not as good as gel PVC powder

[0006] However, the modified polyvinyl chloride involved in the prior art can only meet part of the use requirements of the charging pile cable, and achieve comprehensive performance indicators, that is, it has high tensile strength, high tear strength, heat resistance at 125°C, Cold resistance to -50°C, good aging resistance, gasoline resistance, good engine oil resistance, flame retardant V0 grade cables up to VW-1 grade, matte surface texture and high-end performance, etc., do not exist, which restricts its use in charging pile cables application in
