Health care type shoe material and molding process thereof

Abstract

The invention discloses a health care type shoe material and a molding process thereof. The health care type shoe material comprises an upper surface in direct contact with the human foot, and a plurality of coffee powder particles exposed outside are embedded on the upper surface. The coffee powder particles have a particle size of 50-800 mesh. The molding process comprises the following steps that 1, recycled coffee grounds and / or coffee powder ground from coffee beans are selected and further ground until reaching 50-800 mesh, wherein the proportion of the coffee powder in the coffee powderparticles exceeds 50% by weight; 2 the coffee powder particles and a sole main material are mixed to be uniform, and then subjected to banbury mixing, open milling and screw extrusion to obtain a shoe raw material, and then the shoe raw material is put into an injection molding machine to obtain a finished health care shoe material, wherein the coffee powder particles accounts for 10-20% by weight of the entire shoe material. Compared with the prior art, the health care type shoe material and the molding process thereof allow the coffee powder particles to be in direct contact with the foot of a human body under the basis of ensuring the wearing comfort of the shoe material, thereby achieving a better health care effect.

Description

technical field [0001] The invention relates to the field of new materials for shoe soles, in particular to a health-care shoe material and its molding process. Background technique [0002] The soles currently on the market are generally made of EVA, TPU, PVC or other plastics suitable for cross-linking and foaming after foaming, so that soles with better shock absorption performance can be obtained, but these soles are generally used to solve the problem of On the problem of odor, it is generally realized by setting a ventilation structure. At present, the Chinese invention patent document CN109349738A discloses an insole that can be used for military training or expansion training. The insole is composed of a surface layer, an absorbent core layer and The bottom layer consists of three parts, and the materials of each layer are bonded with hot melt adhesive; the absorbent core layer is vertically embedded with a coffee grounds area and an aroma material area, and the grou...
