Abstract

The invention relates to a pair of soles and particularly relates to a pair of soles of ejection foamed rubber-plastic sports shoes and a manufacturing method of the soles. The pair of soles of the ejection foamed rubber-plastic sports shoes consists of the following raw materials: an ethylene-vinyl acetate copolymer, an ethylene-octene copolymer, a hydrogenated styrene-butadiene-styrene block copolymer, an ethylene propylene diene monomer, polysiloxane resin, talcum powder, stearic acid, zinc stearate, zinc oxide, dicumyl peroxide, azobisformamide and masterbatch. The manufacturing method comprises the steps of: mixing the dicumyl peroxide and an azo foaming agent for later use, mixing other raw materials and then pouring into an internal mixer for first-stage internal mixing, then adding a mixture of the dicumyl peroxide and the azo foaming agent for second-stage internal mixing to obtain an internally mixed mixture, thinning the mixture on a roller machine, conveying the material which is evenly mixed by the roller machine into a granulator for granulation, proportioning aggregates after granulation according to set ratios, injecting the aggregates into a shoe mould by using an injection molding machine for molding, and sizing the molded soles into foamed profile products by using an incubator.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a foamed rubber and plastic sports shoe sole and a manufacturing method thereof. Background technique [0002] Rubber and plastic shoe material is a new type of chemical material between rubber and plastic. It has both some properties of rubber and some characteristics of plastic. [0003] The development of sports shoe soles has gone through vulcanized soles, PU soles, rubber soles, EVA foam soles, etc. With the improvement of the professional level of shoemaking, the comfort of sports shoes, the simplification of the process flow, and the reduction of costs are the key factors for the manufacturing of sports shoes. The primary goal pursued by shoe workers for a long time. The foamed rubber and plastic sports shoe sole is another shoe material research result successfully developed by the shoe material research and development personnel after years of experiments and under the guidance of the con...
