Novel thermoplastic elastomer

The invention discloses a novel thermoplastic elastomer. The elastomer comprises the following components in parts by weight: 30-40 parts of ethylene-acrylic acid copolymer, 30-40 parts of ethylene-acrylic acid-methyl ester copolymer, 40-55 parts of modified polypropylene, 5-10 parts of paraffin oil, 10-20 parts of plasticizer, 10-15 parts of organic silica gel, 5-8 parts of hydrogenated white oil, 2-5 parts of calcium carbonate, 2-5 parts of talcum powder and 2-5 parts of carbon black. According to the invention, the dispersion of fillers in the thermoplastic elastomer can be effectively reinforced; and the elastomer has the advantages of environmental friendliness, no toxicity, long thermal stabilization time, good polymer intermiscibility, low volatility, capability of restraining effusion, high extender volume, high product brightness and the like.
