Abstract

The invention relates to a PE-PS alloy with a high conductivity, which comprises, by weight, the following components: 20-40 parts of PE; 30-50 parts of PS; 5-10 parts of PBT; 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; 0.2-0.4 part of a coupling agent. According to the invention, the compatibility ofthe system can be effectively improved through anhydrous MgCl2, so that the performance of the alloy is improved; the main reason is that MgCl2 can initiate an alkylation reactor between the PE and the PS, and a produced graft PE-g-PS can improve the compatibility of PE-PS blend, so the physical properties of the PE-PS alloy can be improved to different degrees.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PE-PS alloy with high conductivity. 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 blending polyethylene and polystyrene to prepare alloys to combine t...
