Anti-static material for manufacturing soles and preparation method of anti-static material

Abstract

The invention discloses an anti-static material for manufacturing soles and a preparation method thereof, the anti-static material comprises the following components in percentage by weight: 90-95% of nitrile rubber and PVC (polyvinyl chloride) mixture, 1-5% of heat stabilizer, 1-5% of conductive powder, 1-5% of flow promoter and 1-5% of coupling agent, and the ratio of the heat stabilizer to the conductive powder to the flow promoter to the coupling agent is as follows: 1-5% of nitrile rubber and PVC mixture, 1-5% of heat stabilizer and 1-5% of conductive powder to 1-5% of flow promoter to 1-5% of coupling agent. 1%-3% of heat stabilizer, 1%-5% of conductive powder, 1%-5% of flow promoter and 1%-3% of coupling agent. The flow promoter can greatly improve the melt index of various plastics, increase the processing fluidity of the plastics, reduce the mixing difficulty of materials, shorten the mixing processing time and improve the mixing uniformity. The preparation method comprises the following steps: adding nitrile rubber and plastic filler into an internal mixer, and then fully stirring and fusing a rubber additive and rubber juice in a liquid state in the internal mixer; and the conductive additive and the flow promoter are added, so that the consumption of various rubber additives can be minimized through fusion in a liquid state.

Description

technical field [0001] The invention relates to the field of shoemaking, in particular to an antistatic material for making shoe soles and a preparation method thereof. Background technique [0002] The rubber foam bottom is a bottom fabric made of rubber closed-cell or open-cell foam materials made of natural or artificial rubber. Half a century ago, people used this material in large quantities for sneakers, sports shoes, travel shoes, liberation shoes, casual shoes, etc. It has excellent elasticity, good tear resistance, aging resistance, corrosion resistance, electrical insulation and other properties, and anti-static is also one of the needs of labor insurance shoes. [0003] In the anti-static processing of shoe soles, it is necessary to use anti-static materials for shoes, but the existing anti-static materials are filled with carbon black or carbon fiber to achieve the effect of conductivity and anti-static, so the color of the soles can only be black , cannot be m...

Problems solved by technology

[0003] In the anti-static processing of shoe soles, it is necessary to use anti-static materials for shoes, but the existing anti-static materials are filled with carbon black or carbon fiber to achieve the effect of conductivity and anti-static, so the color of the soles can only be black , cannot be made into red and yellow colors that are more eye-catching and have a prompt effect, and the materials are not mixed thoroughly in the production process of anti-static materials, resulting in uneven texture. In later use, the mixed materials have insufficient mechanical strength and poor anti-static effect , affect the use of safety and service life
