Abstract

The invention discloses a thermoplastic elastomer composition as well as a preparation method and application thereof. The composition is prepared from the following raw materials in parts by weight:20-150 parts of a mixture of SEPS, SEEPS or SEPS and SEEPS, 20-150 parts of an ethylene-octene block copolyalkenamer, 20-200 parts of paraffinic oil, 20-160 parts of maleic anhydride grafted butadiene, 20-150 parts of maleic anhydride grafted polypropylene, 10-200 parts of rubber powder, 10-100 parts of silicone powder, 10-50 parts of an inorganic filler, 1.9-10 percent of DCP master batches, 1.9-10 percent of TMPTMA and 30-50 parts of PP particles. The preparation method comprises the following step of blending a thermoplastic elastomer material and the rubber powder with a two-step method toform a new thermoplastic elastomer blending system. A floor prepared by adopting the thermoplastic elastomer is high in wet traction, wear resistance and weather resistance.

Description

technical field [0001] The invention belongs to the field of polymer modified materials and their production and processing, and in particular relates to a thermoplastic elastomer composition and its preparation method and application. Background technique [0002] Floors for sports venues are required to have the following properties at the same time: good impact absorption performance and good ball rebound performance, and require wet slip resistance and wear resistance. The impact absorption performance can reduce the damage to the leg joints. The solution is usually to use low-density foam materials. However, due to the relatively high compression rate of low-density foam materials, it is easy to cause uneven floor thickness and dents after long-term trampling. , which in turn affects the use of the product, and the rebound performance of the ball cannot meet the design requirements. [0003] For this reason, a hard bottom structure is often used in the prior art, and a...
