Problems solved by technology

However, ordinary SIS cannot firmly bond ABS and PC materials. Therefore, it is of great practical significance to develop TPE lagging materials that are highly shock-absorbing and can firmly bond ABS and PC. They can be widely used in electronic and electrical sheaths, sports protection Pads and other products, broad application prospects

Abstract

The invention relates to the technical field of thermoplastic elastomer materials and particularly relates to a high-shock-absorbance wear-resistant thermoplastic elastomer and a preparation method thereof. The high-shock-absorbance wear-resistant thermoplastic elastomer comprises the following components in parts by weight: 40-60 parts of SIS resin, 10-20 parts of thermoplastic polyurethane, 5-10 parts of a compatilizer, 5-15 parts of extending oil, 5-10 parts of mineral filler, 1-3 parts of a processing aid and 0.2-0.5 part of an antioxidant. The preparation method comprises the following steps of firstly, placing the SIS resin, carbonate calcium, the antioxidant, the processing aid and extending oil into a high-speed mixer, mixing, adding other raw materials and mixing to obtain a premix; and secondly, placing the premix into a twin-screw extruder, extruding and granulating. The thermoplastic elastomer has the characteristics of capability of secondary injection molding, good adhesion with PC and ABS materials and high shock absorbance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomer materials, in particular to a high shock-absorbing and wear-resistant thermoplastic elastomer and a preparation method thereof. Background technique [0002] Thermoplastic Elastomer (TPE) is a new type of material that can be molded alone, and can be coated on the surface of PC, ABS and other materials by secondary injection molding or co-extrusion. It can obtain good adhesion without adhesives, thus obtaining The soft feel makes the product have anti-skid, anti-impact and other functions. [0003] Chinese patent "CN101760001A A thermoplastic elastomer composition for bonding ABS and its preparation method" discloses a thermoplastic polyurethane (TPU) and styrene-ethylene-butylene-styrene block copolymer (SEBS) It is a thermoplastic elastomer material used as a basic raw material for bonding ABS. However, thermoplastic polyurethane (TPU) has the disadvantages of too strong rigidi...
