NOVELTY - High-damping thermoplastic elastomer comprises 20-50 wt.% styrene-based elastomer, 30-60 wt.% plasticizer, 5-20 wt.% petroleum resin, 0-20 wt.% heat conducting agent, 0.1-0.3 wt.% antioxidant, 1-3 wt.% lubricant, 0.4-1 wt.% light stabilizer, and 1-3 wt.% color master batch. USE - High-damping thermoplastic elastomer. ADVANTAGE - The high-damping thermoplastic elastomer has high heat conductivity and wide temperature range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing high-damping thermoplastic elastomer, which involves: (1) adding the styrene elastomer and plasticizer into the high speed stirrer according to the predetermined weight, then stirring for 10℃, adding the rest predetermined mass parts raw material the heat conducting agent into the high speed stirrer and stirring for 10 hours, extruding and granulating by a double-screw extruder to obtain product 1; and (2) adding the product 1 and heat-conducting agent of the predetermined weight into a high speed stirrer and stirring for 5 hours, extruding and granulating the blended product by a single-screw extruder to obtain desired product.
