Antistatic high-strength polypropylene particles and preparation method thereof

Abstract

The invention discloses antistatic high-strength polypropylene particles, which are prepared from the following components by weight: 100 parts of polypropylene particles, 0.5-1 part of an antioxidant, 8-10 parts of a plasticizer, 5-10 parts of a light stabilizer, 5-10 parts of a lubricant, 30-40 parts of a filler, and 1-2 parts of an antistatic agent, wherein the polypropylene particles are homopolypropylene, has isotacticity of 90-95%, and has molecular weight of 180000-200000, the antioxidant is 2,6-tributyl-4-methylphenol, the plasticizer is triethyl citrate, the light stabilizer is hydroxybenzotriazole, the lubricant is zinc stearate, the filler is calcium carbonate and talc powder, and the antistatic agent is H95 and Atmos 150. According to the present invention, the research resultsshow that the tensile strength can be increased while the antistatic property can be improved by compounding the antistatic agent H95 and the antistatic agent Atmos 150 sp as to overcome the technical bias in the field.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to an antistatic high-strength polypropylene particle and a preparation method thereof. Background technique [0002] Due to the electrical insulation of plastic products, static electricity will accumulate when plastics are in contact or rubbed with other materials. If the accumulated static electricity is not eliminated in time, it may lead to electrostatic adsorption, dust absorption, activation discharge, etc., causing plastic to burn or even explode. For this reason, antistatic agents are usually added to the composition of plastics to achieve antistatic effects. The traditional antistatic agent is a kind of surfactant, which has a hydrophilic group and a lipophilic group, and has a certain compatibility with the polymer, which can be precipitated on the surface of the polymer. The lipophilic group is planted inside the polypropylene resin matrix...

AI Technical Summary

Problems solved by technology

[0003] At present, adding antistatic agents to plastics often leads to a decrease in the tensile strength of plastics. The reason is that after the antistatic agent reaches a certain concentration, it is easy to affect the overall tensile strength of the plastic due to local enrichment.
