AI Technical Summary

Problems solved by technology

However, in order to ensure that the polypropylene material has sufficient antistatic properties, the addition of conductive carbon black is often relatively high, and too much conductive carbon black will lead to a decrease in the strength of the polypropylene material, that is, the existing polypropylene material is resistant to static electricity. It is difficult to balance electrostatic performance and mechanical strength

Abstract

The invention provides a self-lubricating anti-abrasion polypropylene composite material and a preparation method and application thereof. The polypropylene composite material comprises, by mass, 30-50 parts of polypropylene, 20-40 parts of metallocene polyethylene, 3-10 parts of compatilizer, 20-30 parts of conductive carbon black, 1-5 parts of alkylation graphene, 1-3 parts of organic silicon oil, 18-23 parts of red phosphorus flame retardant and 3-6 parts of antimony trioxide. The polypropylene composite material is obtained by extruding all the components in the formula through an extruder. According to the material, the crystallinity of polypropylene and the anisotropy during formation are reduced by using the metallocene polyethylene; the alkylation graphene is matched with the conductive carbon black, so that the resistivity of the material is reduced, and the polypropylene composite material has good dimensional stability, tensile strength, toughness, ductility, flame retardancy, self-lubricating property, abrasive resistance, heat and cold resistance, acid and alkali resistance, corrosion resistance and long-acting and stable antistatic performance, and can be applied to the field of protective electronics industry.
