Abstract

The invention relates to a production technology of a shoe sole, in particular to a light-weight and shock-absorbing combined shoe sole and a production method thereof. The combined shoe sole consists of an outsole and a midsole, wherein the outsole is produced from a rubber material by mixing, performing open mixing, vulcanizing and other processes; the midsole is produced from an EVA material by mixing, performing open mixing, granulating, foaming once, and performing oil pressing twice. The raw materials and the processes of the light-weight and shock-absorbing combined shoe sole provided by the invention are optimized, so that various problems of the rubber material and the EVA material in application are effectively solved; a finished product is light in weight, good in resilience and excellent in shock-absorbing effect, and is not prone to aging and frosting problems.

Description

technical field [0001] The invention relates to a processing technology for shoe soles, in particular to a light-weight, shock-absorbing combined shoe sole and a manufacturing method thereof. Background technique [0002] Consumers are increasingly focusing on comfort and safety when choosing footwear, especially athletic and casual footwear. In order to ensure that the shoes can be light, not bound, and have better shock-absorbing and rebounding properties when worn, more and more attention has been paid to the improvement and development of shoe soles in this field, and many functional shock-absorbing products have emerged. Commonly used outsole materials are all kinds of wear-resistant rubber, and midsole materials are mostly made of light weight, good resilience EVA or PU foam materials, but these materials also have some problems in use, such as rubber materials have aging, Frost is difficult to control. As the EVA material of the midsole, there are problems such as la...
