Abstract

The invention relates to a leather sole, and concretely relates to an injection molded leather sole and a making method thereof. The injection molded leather sole comprises plastic styrene butadiene rubber, hydrogenated styrene-butadiene-styrene segmented copolymer, ethylene-butylene copolymer, ethylene propylene diene monomer, white carbon black, talcum powder, naphthenic rubber oil, stearic acid, zinc stearate, zinc oxide, PEG4000, polysiloxane resin and dicumyl peroxide. The method comprises the following steps: mixing raw materials except dicumyl peroxide, carrying out first stage internal mixing, adding dicumyl peroxide when the temperature reaches 110-113DEG C, carrying out second stage internal mixing to obtain a well mixed mixture when the temperature rises to 115-118DEG C, thinning twice, and granulating; standing, injection the obtained material into a shoe die, and molding under the following conditions: the temperature of the is 178-182DEG C, and the vulcanizing time is 230-270s; and carrying out cooling molding on the above obtained sole to obtain the injection molded leather sole.

Description

technical field [0001] The invention relates to a leather sole, in particular to an injection leather sole and a manufacturing method thereof. Background technique [0002] my country is a big country in the production and export of footwear, and there are all kinds of shoes, among which the share of leather shoes cannot be ignored. With the curtain call of the 2008 Olympic Games, the overproduction of sports brands, and the reincarnation of people's consumption concepts, the proportion and frequency of leather shoes used in each of our lives began to rise.
