Thermoplastic elastomer material for replacing PVC coated polyester yarns and preparation method thereof

The invention discloses a thermoplastic elastomer material for replacing polyvinyl chloride (PVC) coated polyester yarns and a preparation method thereof. The thermoplastic elastomer material consists of the following raw materials in part by weight: 50 to 80 parts of matrix resin, 5 to 20 parts of softening plasticizer, 3 to 15 parts of mineral filler, 5 to 15 parts of compatilizer, 0.2 to 2 parts of lubricant and 0.2 to 0.5 part of stabilizer. All the raw materials are mixed uniformly in a high-speed mixer according to the proportion, and the uniformly mixed raw materials are extruded, pulled, cooled and granulated on a common double-screw extruder to form the thermoplastic elastomer material for replacing the PVC coated polyester yarns. The invention has an obvious advantage that the thermoplastic elastomer material for replacing the PVC coated polyester yarns has no special requirement for the equipment in a coated polyester yarn extrusion processing technique, namely the conventional stand for PVC extrusion can meet the extrusion requirement of the thermoplastic elastomer material for replacing the PVC coated polyester yarns, so the production cost is saved for a manufacturer.
