High-smooth extrusion-grade thermoplastic elastomer

The invention relates to a thermoplastic elastomer, in particular to a high-smooth extrusion-grade thermoplastic elastomer and belongs to the field of high polymer materials. The high-smooth extrusion-grade thermoplastic elastomer provided by the invention comprises the following components in parts by weight: 40-50 parts of SEBS (Styrene-Ethylene-Butylene-Styrene), 6-12 parts of homopolymerized PP (Polypropylene), 30-40 parts of white oil, 5-10 parts of a compounded smoothening agent, 2-5 parts of modified hollow glass beads, 5-10 parts of a lubricant, 5-10 parts of nano calcium carbonate and 0.2-0.4 part of an antioxidant. Due to addition of homopolymerized PP and the white oil, the compatibility of the components is improved, so that the smoothness and the flowability of the thermoplastic elastomer are improved, and in addition, due to addition of nano calcium carbonate, the obtained thermoplastic elastomer is excellent in mechanical property. 本发明涉及种热塑性弹性体，具体涉及种高爽滑挤出级热塑性弹性体，属于高分子材料领域。本发明的种高爽滑挤出级热塑性弹性体，包括以下
