Abstract

The invention discloses an environment-friendly flexible PVC (polyvinyl chloride) cable material and belongs to the field of semiconductive shielding materials. The environment-friendly flexible PVC cable material is prepared from raw materials in parts by weight as follows: 100 parts of PVC, 15-40 parts of a calcium/zinc compound stabilizer, 40-60 parts of a plasticizer, 10-15 parts of epoxidized soybean oil, 5-10 parts of epoxidized butyl oleate, 20-30 parts of calcium carbonate, 10-20 parts of calcined clay and 1-5 parts of a lubricating agent. The cable material does not contain heavy metal such as cadmium, chromium, mercury and the like harmful to a human body and the environment or hazardous substances of PBBs (polybrominated biphenyls) and PBDEs (poly brominated diphenyl ethers).

Description

technical field [0001] The invention belongs to a cable material, in particular to an environment-friendly soft polyvinyl chloride cable material. Background technique [0002] Ordinary soft polyvinyl chloride (PVC) cable material is easy to process, has superior performance, has excellent electrical insulation performance, and is widely used in low-voltage wires and cables. However, ordinary PVC cable materials contain a certain amount of harmful substances such as lead and cadmium, which has become an important factor restricting the application of PVC in electrical equipment, infrastructure and other occasions. At present, there is a great demand for environmentally friendly cable materials at home and abroad. Developed countries such as Europe and the United States have successively formulated environmental protection standards for heavy metal elements such as lead, cadmium, and mercury, and polybrominated biphenyls and other environmentally harmful substances. Lead-fre...
