The invention relates to a thermoplastic elastomer and a preparation method thereof. The thermoplastic elastomer is prepared from the following raw materials in parts by mass: 5-20 parts of SEBS; 10-27 parts of mineral oil; 20-50 parts of thermoplastic polyester elastomer; 10-40 parts of flexible acrylate resin; 3-10 parts of a polar compatilizer; 5-20 parts of mineral filler; 0.1 to 0.5 portion of anti-UV agent; wherein, the number average molecular weight of the SEBS is 60000-120000. The thermoplastic elastomer has good yellowing resistance and outstanding high-gloss effect, improves the peeling strength of the ABS, and has good coating effect on the ABS. In addition, the thermoplastic elastomer has smooth and fine surface, good tensile strength and fluidity, large adjustable hardness range, wide application and convenient processing. |
