Making method of polyvinyl chloride plastic, and making method of charging pile connecting cable sheath material

Abstract

The invention discloses a making method of a polyvinyl chloride plastic, and a making method of a charging pile connecting cable sheath material. The making method of the polyvinyl chloride plastic is characterized in that the polyvinyl chloride plastic adopts SEBS rubber and nitrile rubber as auxiliary plasticizers, and concretely comprises 100 parts of polyvinyl chloride resin, 10-30 parts of dicapryl phthalate, 1-20 parts of dioctyl sebacate, 2-10 parts of a calcium and zinc composite stabilizer, 0-25 parts of the nitrile rubber, 5-25 parts of the SEBS rubber and 0-50 parts of calcium carbonate. The SEBS rubber is a linear or star-shaped triblock copolymer with styrene as an end segment and an ethylene-butylene copolymer obtained after butadiene hydrogenation as a middle elastic copolymer. The nitrile rubber with the acrylonitrile content of 25-35% is used as a compatilizer in the making process of the polyvinyl chloride plastic. The invention also discloses a making method of the charging pile connecting cable sheath material made from the polyvinyl chloride plastic.

Description

technical field [0001] The invention relates to a method for making plastic and a method for making a sheath material using the plastic, in particular to a method for making polyvinyl chloride plastic and an electric vehicle charging pile connection made of the polyvinyl chloride plastic. Manufacturing method of cable sheathing material. Background technique [0002] The car charging pile cable used to connect electric vehicles to the power supply is one of the key equipment of the electric vehicle conductive charging system. The performance of this type of cable will have a direct impact on the safe and reliable operation of electric vehicle charging. The performance of the sheath material of the cable is one of the key factors determining the life of the cable. [0003] Electric vehicle charging pile cables are usually placed on charging piles in roads, garages, hotels, shopping malls, and parking lots for long-term use. Cables may be affected by various adverse environm...

AI Technical Summary

Problems solved by technology

Cables may be affected by various adverse environments including sunlight, weathering, humidity, sea water, oil pollution, acid rain, freezing, etc. At the same time, they are often bent and dragged during use, and mechanical damage such as friction, scraping, and crushing will inevitably occur
