Abstract

The invention provides a high-resilience foamed shoe midsole material and its preparation method and application. The shoe midsole material is made of a thermoplastic resin composite material through 3D printing to form a shoe sole blank, and then made by a supercritical fluid foaming molding process. The thermoplastic resin composite material comprises: 55 to 100 parts of thermoplastic polyurethane resin; 0 to 50 parts of thermoplastic elastomer resin; 0.2 to 5 parts of compatibilizer; 0.5 to 10 parts of nucleating agent; 0 to 1.2 parts 0-1.2 parts of stearic acid; 0-0.9 parts of cell stabilizer. The shoe midsole material has a 3D structure, is light in weight, and has the advantages of high resilience, low compression deformation, and high cushioning performance. In addition, the shoe midsole material of the present invention is formed by 3D printing, impregnated with supercritical fluid, and quickly released and foamed. It is green and environmentally friendly, has a shorter preparation process, higher efficiency, and can realize personalized customization.

Description

technical field [0001] The invention relates to the technical field of shoe manufacture, in particular to a high-elastic foam shoe midsole material and its preparation method and application. Background technique [0002] In recent years, 3D printing technology has been widely used in the shoe industry. 3D printing technology is a technology based on digital model files, which realizes the bonding of materials through layer-by-layer printing, and finally constructs the desired object. 3D printing does not require traditional molds, and can directly print out physical products from three-dimensional graphics of different shapes in the computer. At the same time, the technology has the characteristics of high automation, high efficiency and personalized customization. [0003] Currently developed 3D printing technologies include: fused deposition modeling (FDM), selective laser sintering (SLS), stereolithography (SLA) and digital light processing (DLP). For example, the Chi...
