Abstract

The invention provides a midsole material with natural light transmission. The midsole material comprises a midsole main body with light transmission textures; the air holes are uniformly distributedin the midsole main body, and the shoe insole main body with the light transmission textures is formed by carrying out supercritical extrusion compression molding on a thermoplastic polyurethane elastomer mixed material. Compared with the prior art, the midsole material with natural light transmission provided by the invention has the advantages that the midsole main body with the light transmission textures is obtained by adopting supercritical extrusion compression molding, the air holes which are uniformly distributed are formed, so that internal cavities of a product are reduced, and the material is more stable and does not collapse; the product also has natural light transmission on the basis of good cushioning performance and rebound resilience, can obtain irreplaceable appearance lines and peculiar landscape under light sensation, and is high in cost performance.

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...
