Anti-static sole material for clean room and manufacturing method thereof

Abstract

The invention discloses an anti-static sole material for a clean room. The anti-static sole material comprises the following materials in parts by weight: 76-80 parts of ethylene-vinyl acetate copolymer micelle, 4-5 parts of a bridging agent, 1.2-1.5 parts of bridging additive, 9-11 parts of calcium carbonate, 2.5-3 parts of azobisformamide powder, 1.2-1.3 of dicumyl peroxide powder, 1.6-1.7 parts of zinc oxide powder, 1.2-1.3 parts of stearic acid powder, 3-6 parts of alkylphenol polyoxyethylene ether liquid, 3-6 parts of stearamide propyl dimethyl-b-hydroxyethyl ammonium nitrate liquid, 0.5-1.5 parts of glycerol monostearate particles, 0.5-1.5 parts of ethoxylated alkyl ammonium sulphate solid and 0.5-1.5 parts of ethoxylated alcohol solid. Meanwhile, the invention also discloses a manufacturing method of the anti-static sole material for the clean room. Shoe soles made of the anti-static sole material have excellent and enduring anti-static property; after the products are normally used for 6 mouths, the electrical resistivity of the products still can stabilize in the range from 1 megohm to 35 megohm; and the products are light in weight, have environmentally-friendly effect and are very suitable for application in dust-free plants.

Description

technical field [0001] The present invention relates to a shoe sole material and a manufacturing method thereof, more specifically, to a clean room antistatic shoe sole material and a manufacturing method thereof. Background technique [0002] The production of electronic products requires high-precision equipment and human operation. However, the components of electronic products are protected by static electricity, especially in industries related to semiconductor products. The static voltage resistance of many electronic products is only tens of volts. Static electricity will cause damage to products, so it is very important to strengthen anti-static measures. [0003] Anti-static shoes have been widely used as an electrostatic protection product in clean rooms. [0004] At present, the anti-static soles for clean rooms are mainly made of SPU, PU, ​​PVC and other materials with conductive fibers or other conductive powders, but high-performance conductive materials are v...

AI Technical Summary

Problems solved by technology

[0004] At present, the anti-static soles for clean rooms are mainly made of SPU, PU, ​​PVC and other materials with conductive fibers or other conductive powders, but high-performance conductive materials are very expensive and consume a large amount, and carbon black is easy to The environment is polluted; at the same time, the addition of some antistatic ingredients will make the soles harder, and the production staff will feel fatigued when they wear them for a long time; some materials contain phthalates, which are prone to the danger of plasticizer release; some Odor (including ammonia or other organic flavors); some materials do not have long-lasting antistatic performance and short service life, which poses a risk of harm to the clean room, which is not conducive to market promotion and wide application
