Formula and process for manufacturing TPR antistatic soles and antistatic soles

Abstract

The invention relates to a formula and a process for manufacturing TPR antistatic soles. The formula comprises the following components: 40-46% of styrene-butadiene-styrene block copolymer; 5-8% of styrene-ethylene-butylene-styrene block copolymer; 8-11% of styrene-butadiene copolymer; 6-9% of ethylene-vinyl acetate copolymer; 5-8% of high impact polystyrene; 8-11% of nano calcium carbonate; 0.2-0.3% of nano zinc oxide; 3-6% of titanium dioxide; 2-4% of slip stopping agent; 2-3% of wear-resisting agent; 0.3-0.6% of stearic acid; 0.3-0.6% of lauroyl diethanol amine; 3-5% of octylphenol polyoxyethylene ether; 3-5% of octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate; 1-3% of pyridinium p-toluenesulfonate; 1-3% of sorbitan fatty acid ester; 0.3-0.6% of plasticizer; 1-3% of bridgingagent; 1-1.5% of bridging auxiliary agent; and 3-4% of white oil. The produced product has excellent antistatic performance, the resistivity is stabilized at 1-35M omega, and the product is soft and comfortable, has good wear resistance, is suitable for being used in a static sensitive dust-free workshop, and provides a reliable solution for low-cost antistatic soles.

Description

technical field [0001] The invention relates to the technical field of antistatic shoe sole processing, and more specifically, relates to a TPR antistatic shoe sole production formula, process and antistatic shoe sole. Background technique [0002] TPR (thermoplastic rubber) material is cheap, the product can be recycled and reprocessed without losing its basic performance, the material is environmentally friendly, halogen-free, non-toxic and tasteless, soft in texture, physical properties and hardness can be adjusted, and it has excellent dynamic fatigue resistance. Widely used in many industrial fields, it breaks the traditional boundary between rubber and plastic, and has more economic and social benefits in terms of energy saving, labor saving and environmental pollution prevention; [0003] Due to the complex compounding system of TPR, the compatibility of the structure of each component, the uniformity of blending and dispersion, etc., it is difficult to modify the ant...

AI Technical Summary

Problems solved by technology

[0003] Due to the complex compounding system of TPR, the compatibility of each component structure, the uniformity of blending and dispersion, etc., it is difficult to modify the antistatic performance of materials.

Ordinary TPR anti-static soles on the market are mainly produced and processed by adding a large amount of carbon powder particles, and the carbon powder conductive particles are contacted by pressure to achieve good anti-static performance. Because this method requires a large amount of carbon powder to be added, the product is often mechanical. The strength is not high, it is not wear-resistant, and it is not resistant to folding. At the same time, the carbon powder in the product is also very easy to fall off, which is harmful to the clean room environment. If it is changed to add metal particles, the cost is very high, so it cannot be widely used in clean rooms. in the industry
