Abstract

This application relates to the field of shoe materials, and specifically discloses a novel TPU sole, comprising an outsole of TPU material and a top film of TPU material, and a filling layer is bonded between the outsole and the top film; wherein the filling layer is made of elastic filler The solid is prepared by polyurethane foaming, and the solid elastic filler is made of one or more of waste leather, EVA waste, shoe and clothing waste, waste rubber and waste fiber; it can reduce the cost of TPU soles and realize waste recycling. The waste utilization of leather, EVA waste, shoe and clothing waste, waste rubber and waste fiber reflects the advantages of environmental friendliness; in addition, the application also provides a preparation method of a new type of TPU sole.

Description

technical field [0001] The present application relates to the field of shoe materials, and more particularly, to a novel TPU sole and a preparation method thereof. Background technique [0002] Thermoplastic Polyurethane Elastomer (TPU), as a special material that combines the high elasticity of rubber and the molding processability of plastic, has excellent comprehensive performance; compared with other thermoplastic elastomers, TPU has high strength, good toughness, wear resistance , cold resistance, oil resistance, acid and alkali resistance, hydrolysis resistance, aging resistance, weather resistance, UV resistance, environmental protection and other excellent properties, widely used in industry, automobile manufacturing, footwear, wire and cable and other fields. [0003] The traditional soles are mainly made of rubber and EVA. Although rubber has good wear resistance, it is not popular because of its heavy quality. Based on the excellent comprehensive properties of po...
