Abstract

The invention relates to the technical field of shoe soles, and particularly relates to a polymer integrally-formed shoe outsole and a preparation method thereof. The shoe outsole comprises a shoe cover in contact with the ground and a shoe midsole integrated with the shoe cover, wherein the shoe cover is a TPU material; the shoe midsole is composed of two kinds of materials of a PU foaming material and a TPU popcorn material, or two kinds of materials of the PU foaming material and an elastic rubber material; and the two materials in the shoe midsole are mixed and poured into the shoe cover,and the shoe outsole is integrally formed. The integrally-formed shoe outsole provided by the invention has the characteristics of light weight, high resilience, wear-resistant and non-slip characteristics and high wearing comfort, and is integrally formed by adopting a plurality of materials, excellent in performance and low in cost.

Description

technical field [0001] The invention relates to the technical field of shoe soles, in particular to a polymer integrally formed shoe outsole and a preparation method thereof. Background technique [0002] As the fourth-generation sole material after rubber, PVC, and SBS, TPU (thermoplastic polyurethane elastomer) has better elasticity, wear resistance, tear resistance, and bending properties, and is a variety of special shoes with extremely high requirements. It is one of the preferred materials for soles of football shoes, skate shoes, hiking shoes, etc. [0003] The existing TPU used in the production of shoe materials is the TPU foaming process. The so-called "TPU foaming process" is actually like popcorn. The TPU is made into granules, and these granules can be thought of as one by one. old corn. Then throw it into a machine, which is similar to a popcorn machine, and after high temperature and high pressure, the corn becomes popcorn, and then uses a steam molding proc...
