Description
Technical field
The present invention relates generally to Material Field, relates in particular to a kind of antistatic pbt material.
Background technology
Polybutylene terephthalate (PBT), weatherability, water absorption 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 halogenated hydrocarbon 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. Adopt glass fibre to strengthen or inorganic fill modification therefore most of, its hot strength, bending strength can be enhanced about more than once, and heat distortion temperature also significantly improves. Can long-term work at 140 DEG C, after glass strengthens, goods vertical, horizontal shrinkage factor is inconsistent, easily makes goods generation warpage.
PBT crystallization rate is fast, and optimum processing method is injection moulding, and additive method is extruded in addition, blowing, coating and various secondary operations moulding, needs predryingly before moulding, and moisture 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 distributor as in automobile, body part, ignitor coil skeleton, insulating lid, gas extraction system parts, motor cycle ignitor, electronic apparatus industry as the deflection coil of television set, kinescope 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, oven parts, electric tool part, housing.
Summary of the invention
The object of the invention is just to provide a kind of antistatic pbt material.
The present invention is achieved by the following technical solutions:
A kind of antistatic pbt material, it is made up of the raw material of following weight parts:
Polybutylene terephthalate (PBT) 81-90, copolymer of maleic anhydride and acrylic acid 2-3, silica 2-3,4,4 '-methyl diphenylene diisocyanate 1-2, potassium titanate 0.7-1, dimethylaminopropylamine 1-2, anhydrous calcium chloride 1-2, ferrous sulfate 0.1-0.3, EMA 2-3, pentaerythrite 2-3, decabromodiphenyl oxide 1-2, processing aid 1-2;
Described processing aid is made up of the raw material of following weight parts:
Tricalcium silicate 1-2, tamarind gum 2-3, silicone master batch 1-2, di-n-octyl sebacate 2-3, oyster shell powder 2-3, ammonium tungstate 0.1-0.3, oxine 0.2-0.4, dimethyl silicone polymer 1-2;
Oyster shell powder, silicone master batch are mixed, after stirring, add di-n-octyl sebacate, at 50-60 DEG C, heating mixes 2-4 minute, adds dimethyl silicone polymer, and 200-300 rev/min of dispersed with stirring 7-10 minute, obtains premix;
By tricalcium silicate and ammonium tungstate mixing and ball milling, add above-mentioned premix and the each raw material of residue, stir, obtain described processing aid.
A preparation method for antistatic pbt material, is characterized in that comprising the following steps:
Silica, ferrous sulfate, EMA are mixed, after stirring, add pentaerythrite, at 60-80 DEG C, be uniformly mixed 3-5 minute, add anhydrous calcium chloride, be stirred to normal temperature; Mixes with the each raw material of residue, high-speed stirred is even, sends into double screw extruder and extrudes, and through tie rod, cooling, pelletizing, dry processing, obtains described antistatic pbt material.
Advantage of the present invention is:
Pbt material antistatic effect of the present invention is good, and antistatic effect is lasting, and comprehensive mechanical property is high, and good heat resistance can be widely used in the parts of some specific work environments of weaving, coal mining and electronic enterprises.
