Environment-friendly 90-DEG C high-flexibility PVC insulating material for charging pile cable and preparation method thereof

Abstract

The invention discloses an environment-friendly 90-DEG C high-flexibility PVC insulating material for a charging pile cable and a preparation method thereof. The 90-DEG C high-flexibility PVC insulating material comprises the following raw materials in parts by weight: 50-80 parts of polyvinyl chloride resin A; 20 to 50 parts of polyvinyl chloride resin B; 5-12 parts of a stabilizer; 20 to 30 parts of a plasticizer A; 10 to 20 parts of a plasticizer B; 2-5 parts of a flexibility improver A; 6-10 parts of a flexibility improver B; 0.5 to 1.5 parts of an antioxidant A; 0.5 to 1.5 parts of an antioxidant B; 0.2 to 0.8 part of a lubricant A; 0.2 to 0.8 part of a lubricant B; 0.2 to 0.8 part of a lubricant C; 6-10 parts of an electrical property enhancer A; 6-10 parts of an electrical propertyenhancer B; 1-3 parts of a forming agent; and 40 to 70 parts of a nano mineral filler. The 90 DEG C high-flexibility PVC insulating material has the advantages that the flexibility is obviously improved; the advantages of high-speed extrusion, smooth and fine extrusion surface and the like are realized; the used raw materials are cheap and easily available, the material cost is reduced; and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to an environment-friendly 90°C high-flexibility PVC insulating material for charging pile cables and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] In formulating the development plan for new energy vehicles, the state pointed out that China will gradually withdraw from fuel vehicles in 2030, and fully launch new energy vehicles before 2040. New energy vehicles will become the dominant vehicle in the future. With the vigorous development of new energy vehicles, the corresponding automotive wiring harness will also develop in a blowout manner. However, the quality of PVC insulating materials for low-voltage automotive wiring harnesses corresponding to automotive wiring harnesses is uneven, the processing speed is slow, it is difficult to meet the technical requirements of international standards, and the price is relatively high.
