Abstract

The invention discloses high-performance conductive engineering plastic. The method for preparing the high-performance conductive engineering plastic is different from the traditional method for increasing the conductivity of the engineering plastics, and comprises the following step: applying graphene to a polymer MPPO (polyphenyl ether / high impact polystyrene blend modified alloy) matrix to form the graphene / MPPO engineering plastic with high conductivity and high strength. The engineering plastic prepared by the method disclosed by the invention maintains the excellent characteristics of MPPO and has excellent conductivity, and the product has more technical characteristics in performance and can be widely applied to the fields of antistatic and electromagnetic shielding materials, electromagnetic shielding materials of electronic products and aerospace equipment, and the like.

Description

Technical field: [0001] The invention belongs to the field of engineering plastics, in particular to an engineering plastic with high electrical conductivity and high strength. Background technique: [0002] Polyphenylene ether is a high-strength engineering plastic developed in the 1960s. Its chemical name is poly 2,6-dimethyl-1,4-phenylene ether, referred to as PPO (Polyphenylene Oxide) or PPE (Polypheylene ether), also known as It is polyphenylene oxide or polyphenylene ether. Unmodified polyphenylene ether (PPO) resin has poor solvent resistance, the product is prone to stress cracking, low notched impact strength, high melt viscosity, and extremely poor processability, so pure PPO resin cannot be molded by injection method, so greatly limited its application. In order to overcome these shortcomings of unmodified polyphenylene ether, physical modification was used to blend PPO with high impact polystyrene (HIPS) to obtain PPO / HIPS type alloy (MPPO). [0003] Compared ...
