Problems solved by technology

Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, can withstand most acid and alkali erosion (not resistant to oxidizing acids), has low water absorption, and has excellent electrical insulation properties. However, polyethylene is very sensitive to environmental stress (chemical and mechanical action), has poor heat aging resistance, and insufficient antistatic performance, which limits its performance and wide application.

Abstract

The present invention discloses polyethylene antistatic powder and a preparation method thereof. The polyethylene antistatic powder comprises, by mass, 60-80% polyethylene, 5-15% of glass fibers, 3-10% of a antistatic master batch, 0.5-2% of a light stabilizer, 0.1-1% of a slipping agent, 0.5-1% of pentaerythrityl tetrastearate, and 0.1-1% of an antioxidant, wherein the antistatic master batch comprises 30 wt% of a polyethylene resin, 40 wt% of sodium alkyl benzene sulfonate, 25 wt% of glycerol monostearate, and 5 wt% of ethylenebis(stearamide). The polyethylene antistatic powder of the present invention has beneficial effects of good permanent antistatic property, high mechanical strength, strong aging resistance, good mobility, excellent electrical performance, and the like, can be used in the fields of chemical industry, machinery, electrical apparatuses, pipelines, packaging and the like, and has good use effects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyethylene antistatic powder and a preparation method thereof. Background technique [0002] Polyethylene is the simplest polymer and the most widely used polymer material. It is linked by repeating –CH2– units. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, can withstand most acid and alkali erosion (not resistant to oxidizing acids), has low water absorption, and has excellent electrical insulation properties. However, polyethylene is very sensitive to environmental stress (chemical and mechanical action), has poor heat aging resistance, and insufficient antistatic performance, which limits its performance and wide application. Contents of the invention [0003] The object of the present invention is to provide a polyethylene antistatic powder with high heat resistance, strong impact resi...
