振动力场作用下TPE力学性能与形态结构实验研究

An Experimental Study of the Mechanical Properties and Morphological Structure of TPE under Vibration Force Field

利用开发设计的振动诱导动态全硫化实验装置,对稳态与动态条件下TPE的宏观力学性能和微观形态结构进行了研究.实验结果表明,振动力场的作用可以提高TPE的拉伸强度、100%定伸应力和扯断伸长,改善TPE的硬度.随着振动强度的增加,分散相粒径减小,获得均匀细致的“海-岛”结构.

The Mechanical properties and morphological structure of TPE in steady and dynamic states are studied through the experimental device of vibration-induced dynamic vulcanization. The experimental results show that, under vibration force field, tensile strength, tensile stress at 100% and elongation at break of TPE can be enhanced, and hardness （shore A） of TPE can be improved. With the increase of vibration strength, the dispersed phase dimension decreases, and even and fine islands-in-sea morphology can be obtained.
