Abstract
The invention relates to a halogen-free thermoplastic elastomer cable material. The cable material includes the following raw material components and parts by weight: 20-40 parts by weight of elastomer resin; 3-25 parts by weight of polypropylene; 10-25 parts by weight of polyolefin resin. 40 parts by weight; 10-25 parts by weight of compatibilizer; 20-40 parts by weight of halogen-free flame retardant; 0.5-2.0 parts by weight of antioxidant; 10 parts by weight of processing aid; 5-20 parts by weight of lubricant. The halogen-free thermoplastic elastomer cable material of the present invention. It does not contain halogen and heavy metal elements, etc., it is harmless to the environment, and can be recycled repeatedly. It has excellent flame retardancy and mechanical properties, and is suitable for electric vehicle charging pile cables.
Description
technical field [0001] The invention relates to a cable material, in particular to a thermoplastic elastomer cable material and a preparation method thereof. Background technique [0002] Hydrogenated polystyrene-(ethylene-butylene random copolymer)-polystyrene triblock copolymer (SEBS) is a thermoplastic elastomer with excellent performance, which has excellent weather resistance, aging resistance, heat resistance and compression deformation resistance , Recyclable reuse and other properties, so it is widely used in electrical cables, automobile manufacturing, construction and other fields. However, flammability restricts the wide application of SEBS. Therefore, using the mechanism of expansion and flame retardancy of the new halogen-free intumescent flame retardant after combustion, excellent flame retardant performance can be achieved with a small amount of flame retardant, while maintaining SEBS itself has excellent mechanical properties and soft properties.
