Abstract

The invention discloses an electric conduction pbt material. The electric conduction pbt material comprises, by weight, 72-80 parts of polybutylene terephthalate, 2-3 parts of ethyldiol methacrylate, 1-2 parts of tea saponin, 5-10 parts of graphene, 2-3 parts of brominated polystyrene, 0.8-1 part of potassium perfluorobutanesulfonate, 3-4 parts of epoxidized soybean oil, 1-2 parts of 1H-Imidazole-1-ethanol, 0.1-0.2 part of sodium persulfate, 2-3 parts of polyethylene glycol 1000, 0.6-1 part of polyimide and 1-2 parts of processing agents. The graphene is added in the pbt material, the surface specific resistance of a finished matrix can be effectively reduced, the electric conduction performance is superior, and the electric conduction pbt material is especially suitable for automobiles, electric products, mechanical parts and the like.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a conductive PBT material. Background technique [0002] Polybutylene terephthalate has low weather resistance and water absorption rate of only 0.1%. It still maintains various physical properties (including electrical properties) and electrical insulation in a humid environment, but its volume resistance and dielectric loss are large. Resistant to hot water, alkalis, acids, oils, but easily corroded by halogenated hydrocarbons, poor hydrolysis resistance, rapid crystallization at low temperature, good formability. The disadvantage is that the notched impact strength is low and the molding shrinkage is large. Therefore, most of them are reinforced by glass fiber or modified by inorganic filling, the tensile strength and bending strength can be more than doubled, and the heat distortion temperature is also greatly increased. It can work at 140°C for a long time. After glass ...
