preparation example Construction

[0053] The embodiment of the present invention provides a method for preparing the high resilience foamed shoe midsole material as described above, which includes the following steps:

[0054] Melt and knead each component in the thermoplastic resin composite material, extrude or grind to obtain a printing material, and print it by a 3D printer to obtain a shoe sole blank;

[0055] The shoe sole blank is immersed in a high-pressure fluid atmosphere to balance, then the pressure is quickly released, dried and aged to obtain a high resilience foamed shoe midsole material.

[0056] See Figure 4 , Figure 4 These are the front and back side views of the foamed 3D structure of the injection molded shoe midsole in some embodiments of the present invention.

[0057] In the embodiment of the present invention, each component in the thermoplastic resin composite material is weighed in parts by weight. In some embodiments of the present invention, the weighed thermoplastic elastomer composit...

Abstract

The invention provides a high-elastic foamed shoe insole material, and a preparation method and an application thereof, wherein the insole material is prepared by 3D-printing a thermoplastic resin compound material to form a green body, and performing supercritical fluid foaming shaping. The thermoplastic resin compound material includes: 55-100 parts of thermoplastic polyurethane resin, 0-50 parts of thermoplastic elastomer resin, 0.2-5 parts of a compatibilizer, 0.5-10 parts of a nucleating agent, 0-1.2 parts of an antioxidant, 0-1.2 parts of stearic acid, and 0-0.9 parts of a foam pore stabilizer. The insole material has a 3D structure, is light in weight, and has advantages of high resilience, low shrinking deformation and high cushioning effect. The insole material is shaped through 3D printing with the supercritical fluid impregnation and rapid pressure relief foaming. The method is green and environment-protective, is shorter in preparation process and higher in efficiency, andcan achieve customization.

Description

Technical field [0001] The invention relates to the technical field of footwear manufacturing, in particular to a high-elastic foaming shoe midsole material and a preparation method and application thereof. Background technique [0002] In recent years, 3D printing technology has been widely used in the shoe industry. 3D printing technology is a technology that uses digital model files as the basis to realize the bonding of materials through layer-by-layer printing, and finally construct the required objects. 3D printing does not require traditional molds, and can directly print three-dimensional graphics of different shapes in the computer into physical products. At the same time, the technology has the characteristics of high automation, high efficiency and individual customization. [0003] The currently developed 3D printing technologies include: Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), Stereolithography (SLA) and Digital Light Processing (DLP). For ...
