Extinction type thermoplastic elastomer for preparation of wire and cable

Abstract

The invention discloses an extinction type thermoplastic elastomer for preparation of a wire and a cable. The extinction type thermoplastic elastomer is characterized by being preparing from the following raw material components by weight percent: 20-60% of styrene elastomer, 20-50% of mineral oil, 0-40% of reinforcing agent, 5-40% of extinction modification material, 0.1-1% of antioxidant, 0.1-1% of processing aid and 5-20% of mineral filling material, wherein the reinforcing agent is at least one of allyl resin and styryl resin, and the extinction modification material is dynamically-vulcanized thermoplastic elastomer or crosslinkable resin / crosslinking agent composition. The extinction type thermoplastic elastomer has the advantages that the crosslinkable resin / crosslinking agent composition or thermoplastic vulcanized rubber is adopted in a basic material, thus the matt effect is good, and the mechanical property and flowability of the material are not influenced.

Description

technical field The present invention relates to a thermoplastic elastomer, in particular to a matting type thermoplastic elastomer for wire and cable preparation. Background technique Thermoplastic elastomers are gradually replacing PVC and rubber materials for the preparation of various cables and wires due to their good wear resistance, oil resistance, flexibility, elasticity, thermal stability and other mechanical properties. . After the existing thermoplastic elastomers are prepared into wires and cables, they usually have a bright surface. In some specific applications, people hope that the surface gloss of the wires or cables should be as low as possible, which is commonly referred to as having Good "matte" finish. No. 200810038561.3 Chinese invention patent application publication published on December 9, 2009 introduces a kind of environmentally friendly flame-retardant thermoplastic polyurethane elastomer cable material, which has a good "matte" effect on the sur...
