Abstract

The invention relates to the field of soles, in particular to an elastic damping sneaker sole and a preparation process thereof. The sole and the process mainly solve the problem that in the prior art, comfort and mobility of a sports shoe sole are not achieved at the same time. The sole comprises a midsole and an outsole arranged on the lower surface of the midsole, and is characterized in that the midsole comprises 53.2% to 59.3% of a thermoplastic elastomer, 22.2-27.2% of an ethylene-vinyl acetate copolymer, 10.5-14.8% of an olefin block copolymer, 1.1%-2.3% of zinc oxide, 0.5%-0.7% of zincstearate, 0.2%-0.4% of stearic acid, 0.3%-0.7% of a cross-linking agent and 2.4%-4.2% of a foaming agent.

Description

technical field [0001] The invention relates to the field of shoe soles, in particular to an elastic shock-absorbing sports shoe sole and a preparation process thereof. Background technique [0002] As an indispensable daily necessities in people's daily life, shoes are originally only used to protect the feet from the damage of the external environment, so that the safety of walking is guaranteed. With the rapid development of living standards, people have more and more requirements for shoes, so shoes with different functions should be produced, such as sports shoes and travel shoes. [0003] In the past, the soles of most sports shoes were made of synthetic polymer materials such as polyurethane (PU), thermoplastic styrene-butadiene rubber (TPR), and polyvinyl chloride (PVC). These soles have good wear resistance and are easy to process. However, it does not provide much help in terms of sports performance. When a person is exercising, the impact force of the foot's mome...
