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
The present invention relates generally to Material Field, relates in particular to a kind of conduction pbt material.
Background technology
Polybutylene terephthalate, weathering resistance, water-intake rate are low, are only 0.1%, still keep various physical property (comprising electrical property) in wet environment, electrical insulating property, but volume resistance, dielectric loss are large.Heat-resisting water, bases, acids, oils but be subject to halon and corrode, hydrolytic resistance is poor, crystallization rapidly under low temperature, good forming ability.Shortcoming is that notched Izod impact strength is low, and molding shrinkage is large.Therefore most of, adopt glass fibre to strengthen or inorganic fill modification, its tensile strength, flexural strength can be enhanced about more than once, and heat-drawn wire also significantly improves.Can long term operation at 140 ℃, after glass strengthens, goods vertical, horizontal shrinking percentage is inconsistent, easily makes goods generation warpage.
PBT crystallization velocity is fast, and optimum working method is injection moulding, and additive method is extruded in addition, blowing, coating and various secondary processing moulding, needs predryingly before moulding, and moisture content will be down to 0.02%.
PBT(strengthens, modified PBT) be mainly used in automobile, electronic apparatus, industrial machinery and polymer alloy, blend industry.As in the divider as in automobile, body part, ignitor coil skeleton, insulating cover, exhaust system component, motor cycle ignitor, electronic apparatus industry as the deflector coil of televisor, picture tube and potentiometer support, sound accompaniment output transformer skeleton, adapter skeleton, switch connector, electric fan, refrigerator, motor for washer end cap, axle sleeve.
Also have in addition Transport Machinery part, sewing machine and textile machinery part, casing for clock and watch, lens barrel, electric iron cover, mercury lampshade, roaster parts, power tool part, bell housing.
