Abstract

The invention discloses a breathable shoe sole and a production process thereof. The breathable shoe sole comprises the following components in parts by weight: 35-45 parts of natural rubber; 20 to 25parts of ethylene propylene diene monomer; 35 to 45 parts of vinyl silicone rubber; 4-7 parts of a compatilizer; 1.5-3 parts of a vulcanizing agent; 1 to 1.5 parts of an accelerant; 40 to 60 parts ofa filler; 2-3 parts of a foaming agent H2; 2-3 parts of hydroxyl silicone oil; 0.8 to 1.5 parts of an anti-aging agent; 1.5 to 3 parts of activated zinc oxide; and 0.4-0.6 part of stearic acid. A blending system of natural rubber / ethylene propylene diene monomer rubber / vinyl silicone rubber can be well mixed with the help of the compatilizer, so that the sole material has excellent mechanical properties, aging resistance and air permeability, is suitable for being used as soles of leisure leather shoes, and improves the wearing comfort of people.

Description

technical field [0001] The invention relates to shoe soles, in particular to a breathable shoe sole and a production process thereof. Background technique [0002] At present, there are many kinds of shoes, which have various functions according to the difference of purposes and applicable grounds. Common shoes include sports shoes, casual leather shoes, slippers, etc. Among them, casual leather shoes are suitable for people to wear in leisure life at ordinary times, and need to have basic properties such as wear resistance, anti-skid and breathability. At present, casual leather shoes use natural leather or synthetic leather as the vamp, and make the sole with materials such as leather, rubber, foamed PU. [0003] Natural leather is used as the sole material, which has excellent air permeability, so it is called a breathing sole. However, the price of natural leather is high, it is only suitable for high-grade leather shoes, and its wear resistance is poor. Therefore, mo...
