[0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has the advantages of light weight, high strength, insulation, flame retardancy, corrosion resistance, excellent comprehensive performance, low price and wide source of raw materials; but also There are the following disadvantages: 1. The toughness is poor, and it is easy to be brittle when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. The lower limit of general PVC products is -15°C. The lower limit of use of PVC is -30°C; 2. Poor thermal stability, it begins to decompose HCl at 100°C, and decomposes more rapidly when it is higher than 150°C, and the melting temperature of PVC is about 210°C; 3. The viscosity of PVC Extremely high, extremely poor fluidity, which limits its use to a certain extent
[0003] However, the existing PVC materials for car charging piles have defects such as poor anti-static, which limits their use to a certain extent.
