Abstract
The invention discloses an antistatic enhanced poly butylenes terephthalate composite material and preparation method thereof. The composite material comprises, by weight, 100 parts of poly butylenes terephthalate, 3-12 parts of conductive carbon black, 20-25 parts of carbon fiber, 0.8-2 parts of lubricant, 0.3-0.5 part of anti-oxidant and 3-5 parts of antistatic agent. The composite material of the invention has lower specific gravity than a common glass fiber enhanced material, high strength as well as also high temperature toleration of the common glass fiber enhanced material; besides, the material has stable surface resistor and excellent antistatic effect.
Description
Technical field
The present invention relates to technical field of polymer materials, relate in particular to a kind of antistatic enhancing mutual-phenenyl two acid bromide two alcohol ester matrix material and preparation method thereof.
Background technology
Polybutylene terephthalate (PBT) is the linear saturated polyester resin of a kind of crystal type.Its crystallization velocity is fast, but high-speed molding; Weathering resistance, electrical property, flame retardant properties, chemical proofing, friction wear excellent, water-absorbent is low, heat-drawn wire is high; Mechanical property is good, and physical strength is high, resistance to fatigue and dimensional stability are good, and creep is also less, these performances also changes little under hot conditions.But its effect aspect antistatic property is not ideal enough.
Summary of the invention
The technical problem that the present invention will solve provides a kind of antistatic enhancing mutual-phenenyl two acid bromide two alcohol ester matrix material and preparation method thereof.
For solving the problems of the technologies described above, the objective of the invention is to realize through following technical scheme.
A kind of antistatic enhancing mutual-phenenyl two acid bromide two alcohol ester matrix material, its composition is by weight:
Polybutylene terephthalate 100;
Conductive carbon black 3-12;
Thomel 20-25;
Lubricant 0.8-2;
Oxidation inhibitor 0.3-0.5;
Static inhibitor 3-5.
Preferably, said polybutylene terephthalate, its specific density is 1.30～1.34, and fusing point is 222～227 ℃, and its kinetic viscosity is 0.9～1.1Pa.S.
Preferably, said conductive carbon black is one or several composite in conduction oven process carbon black, superconduction oven process carbon black, high electric conductivity oven process carbon black or the acetylene carbon black.
Preferably, said thomel long filament that to be polyacrylonitrile fibre, pitch fibers, viscose yarn or phenolic fibre make through carbonization or in the chopped strand one or several are composite.
Preferably, said lubricant is that in the modified product of OP wax, stearic acid or fatty acid, silicone or ethylene bis stearamide one or several are composite.
Preferably; Said oxidation inhibitor is that four [3-(3; The 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester and tricresyl phosphite (2; 4-di-t-butyl phenyl ester) composite mixture or triglycol be two-a kind of in 3-(3-tertiary butyl-4-hydroxy-5-aminomethyl phenyl) vinyl cyanide, three (2, the 4-di-tert-butylphenol) phosphorous acid ester.
Preferably, said static inhibitor is one or several composite of an alkali metal salt or ethoxylated fat family alkylamine of quaternary ammonium alkyl, phosphorus or phosphonium salt or alkylsulphonic acid, phosphoric acid or the dithiocarbamic acid of long-chain
A kind of aforesaid antistatic enhancing mutual-phenenyl two acid bromide two alcohol ester composite material and preparation method thereof comprises step:
