Abstract

The invention provides an antistatic thermoplastic elastomer material, which comprises a styrene elastomer matrix, polypropylene, white oil, an inorganic filler, a lubricant, an antioxidant and a polymer antistatic agent, wherein the polymer antistatic agent is a polyolefin polymer antistatic agent, and the mass ratio of the antioxidant to the macromolecular antistatic agent is 1: 1. The thermoplastic elastomer material provided by the invention has a good antistatic effect, the surface resistivity ranges from 107 ohms to 1010 ohms, and a permanent antistatic function can be realized. The thermoplastic elastomer material is wide in applicability, the antistatic effect is not affected by adjusting the hardness and specific gravity of the elastomer, the preparation method is simple and easy to implement, pollution is avoided in the processing process, and green preparation is achieved.

Description

technical field [0001] The invention relates to an antistatic thermoplastic elastomer material and a preparation method thereof, belonging to the technical field of materials. Background technique [0002] Thermoplastic elastomer materials have high insulation like most rubbers and plastics. The disadvantage is that a large amount of static electricity will be generated during use, and electrostatic discharge will damage or destroy sensitive electronic components. Therefore, antistatic materials are irreplaceable in some fields. role. [0003] In the prior art, conductive materials or antistatic agents are generally added for compounding during the preparation of antistatic materials. Commonly used conductive materials include conductive carbon black, carbon fiber, graphite, metal powder, etc., but the uneven dispersion of conductive fillers causes surface defects. Therefore, how to use antistatic agents to increase antistatic properties in thermoplastic elastomer materials...
