Shockproof thermoplastic elastomer material as well as preparation method and application thereof

The invention discloses a shockproof thermoplastic elastomer material and a preparation method and application thereof.The shockproof thermoplastic elastomer material is obtained through multi-step polymerization reaction of polymethylacrylic acid-2-hydroxyethyl ester, polyolefin and trimethoxy boron oxide hexacyclic, and the shockproof thermoplastic elastomer material has excellent mechanical property and good shock resistance. The elastomer material is high in breaking elongation and low in rebound rate, has good soft and hard segment conversion capacity, can be rapidly hardened and absorb energy when subjected to high-speed impact through BO dynamic cross-linking bonds in the elastomer material, plays an energy-absorbing and shock-absorbing role, and has a better application prospect in shock-absorbing materials. 本发明公开了一种防震热塑性弹性体材料及其制备方法和应用，所述防震热塑性弹性体材料由聚甲基丙烯酸-2-羟乙酯、聚烯烃和三甲氧基硼氧六环经多步聚合反应得到，该防震热塑性弹性体具有优异的力学性能，断裂伸长率高和回弹率低，具有良好的软硬段转换能力，通过内存在B−O动态交联键，使弹性体材料在遭受高速冲击时可迅速硬化并吸收能量，发挥吸能减震作用，在减震材料上具有较好的应用前景。
