Abstract

The invention relates to a PVC/TPU (polyvinyl chloride/thermoplastic polyurethane) oil-resistant flame-retardant thermoplastic elastomer for new energy automobile charging pile cables. The invention is characterized in that the thermoplastic elastomer is formed by mixing a PVC flame-retardant master batch and modified TPU and carrying out granulation, wherein the mass ratio of the PVC flame-retardant master batch to the modified TPU is 1:1-3:7. The PVC master batch comprises the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin, 70-85 parts of plasticizer, 3-6 parts of stabilizer, 5-10 parts of lubricant, 150-250 parts of inorganic filler, 150-250 parts of flame retardant and 3-7 parts of antioxidant. The plasticizer is composed of a low-viscosity polyester plasticizer and a super-cold-resistant solid plasticizer in a mass ratio of 15:1-11:3. The cable material has the advantages of favorable large-section extrudability, smooth and particle-free surface, favorable wear resistance, favorable oil resistance and favorable flame retardancy, and can operate in an outdoor harsh environment for a long time without failures.

Description

Technical field [0001] The invention belongs to the field of cable and wire materials, and relates to a thermoplastic elastomer, in particular to a PVC / TPU oil-resistant flame-retardant thermoplastic elastomer material for charging pile cables of new energy vehicles. Background technique [0002] In the face of the increasingly serious global environmental crisis and energy depletion, especially the uneven distribution of domestic energy and the increasingly depleted, haze weather, vigorous development of new energy has been elevated to a strategic position in countries around the world. According to the International Energy Outlook issued by the U.S. Energy Information Administration EIA, the world energy market consumption is expected to increase by 50% from 2005 to 2030. As energy consumption increases year by year, carbon dioxide emissions will also increase. At present, 25% of carbon dioxide emissions come from automobiles. By 2030, it will increase from 28.1 billion tons i...
