Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a damping and shock-absorbing thermoplastic elastomer material and a preparation method thereof. Background technique [0002] TPE-based damping and shock-absorbing materials have excellent aging resistance, weather resistance, compression deformation resistance and excellent mechanical properties. They have both plasticity and high elasticity. The scraps can be reused. They are widely used in high-speed railways, washing machines, lathes, etc. Shock absorbing pads and shock absorbing blocks of sports equipment are various shock absorbing elements. However, TPE-based damping and shock-absorbing materials are deficient in high-temperature aging and high-temperature pressure change, which limits their application. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a damping and shock-ab...
