Abstract

The invention relates to a wear-resistant high-electroconductivity PE-PS (polyethylene-polystyrene) alloy, comprising the following components in parts by weight: 20-40 parts of PE, 30-50 parts of PS, 0.3-0.5 part of magnesium chloride, 10-16 parts of a conductive filler, 4-10 parts of a wear-resistant agent, 0.1-0.5 part of an antioxidant, and 0.2-0.4 part of a coupling agent. According to the invention, the compatibility of the system can be effectively improved by virtue of anhydrous MgCl2 to ensure that the performance of the alloy is improved, which is mainly because MgCl2 can cause alkylation reaction between PE and PS, a generated grafting material PE-g-PS improves the compatibility of a PE-PS blend, and then the physical property of the prepared PE-PS alloy is also improved to a different extent.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PE-PS alloy with high wear resistance and electrical conductivity and a preparation method thereof. Background technique [0002] Polyethylene (PE) has been widely used in various fields such as automobiles, home appliances, packaging, and medical treatment because of its low price, excellent performance, wide source, and easy processing, and has become one of the most widely used plastics in modern times. Polyethylene has the advantages of light weight, non-toxic, odorless, good chemical stability, good electrical insulation performance, insoluble in common solvents at room temperature, and low water absorption. [0003] Polystyrene (referred to as PS) has the advantages of excellent thermodynamic properties, good toughness, good chemical resistance, good wear resistance, self-lubrication and excellent electrical insulation. [0004] In recent years, studies on blen...
