An antistatic pbt material

Abstract

The invention discloses an antistatic pbt material. The antistatic pbt material is composed of, by weight, 81-90 parts of pbt, 2-3 parts of maleic anhydride-acrylic acid copolymer, 2-3 parts of silicon dioxide, 1-2 parts of 4,4'-diphenylmethane diisocyanate, 0.7-1 part of potassium titanate, 1-2 part of imethylaminopropylamine, 1-2 parts of anhydrous calcium chloride, 0.1-0.3 part of ferrous sulfate, 2-3 parts of ethyl methacrylate, 2-3 parts of pentaerythritol, 1-2 parts of deca-brominated diphenyl ether and 1-2 parts of processing agents. The antistatic pbt material is good and durable in antistatic effect, high in comprehensive mechanical property, good in heat resistance, and capable of being widely applied to components of certain specific work environments of the textile industry, the coal mining industry and electric product industry.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to an antistatic 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 fib...
