Abstract

The invention provides a shoe midsole material with natural light transmission, comprising: a shoe midsole body with a light-transmitting texture; air holes evenly distributed on the shoe midsole body; the shoe with a light-transmitting texture The midsole body is made of thermoplastic polyurethane elastomer mixture through supercritical extrusion molding. Compared with the prior art, the shoe midsole material with natural light transmission provided by the present invention adopts supercritical extrusion molding to obtain the shoe midsole body with light-transmitting texture, and then arranges evenly distributed air holes to reduce the internal cavity of the product. The material is more stable and will not collapse; on the basis of good cushioning and resilience, the product also has natural light transmission, can obtain irreplaceable appearance lines and strange landscapes under light perception, and is cost-effective.

Description

technical field [0001] The invention relates to the technical field of shoe manufacture, and more specifically relates to a shoe midsole material with natural light transmission and a preparation method thereof. Background technique [0002] Running shoes are mainly divided into three parts: upper, midsole, and outsole. Among them, the midsole, as the soul of running shoes, plays an extremely important role in improving the quality and value of shoes. At present, EVA material has become one of the midsole materials widely used by major shoe factories because of its good softness, elasticity and low cost; E-TPU material, which embodies BOOTS technology in non-EVA midsoles, has a broad market prospect. [0003] BOOTS technology is to expand the solid particle material (TPU) and convert it into thousands of small energy capsules to make the midsole of the shoe. Due to the unique structure, each small capsule can effectively accumulate and release energy, thus providing good per...
