Abstract
The invention provides a kind of high temperature resistant nylon/polyphenylene oxide composite material and preparation method thereof, composite contains：30-50 parts of high temperature resistant nylon, 10-40 parts of polyphenylene oxide, 5-40 parts of mineral filler, 3-5 parts of compatilizer, 0.5-1 parts of coupling agent, 0.5-1 parts of antioxidant and 0.5-1 parts of lubricant；Preparation method includes：30-50 parts of high temperature resistant nylon, 10-40 parts of polyphenylene oxide, 5-25 parts of mineral filler, 3-5 parts of compatilizer, 0.5-1 parts of coupling agent, 0.5-1 parts of antioxidant, 0.5-1 parts of mix lubricant is uniform, obtain mixture；Mixture is added in double screw extruder from main spout, 0-15 parts of mineral filler is added in the double screw extruder from side spout, by obtaining high temperature resistant nylon/polyphenylene oxide composite material after tie rod, cooling, pelletizing and drying；High temperature resistant nylon/polyphenylene oxide composite material of the invention has the advantages that excellent heat resistance, high rigidity, good apparent mass, preferable mobility, easy-formation are processed.
Description
Technical field
The invention belongs to technical field of polymer composite materials, it is related to a kind of nylon/polyphenylene oxide composite material and preparation method thereof.
Background technology
High temperature resistant nylon product mainly including 6T, 6I, 9T, 9I, 10T, 10I, the 12T in semiaromatic polyamide composition etc., be by
Dicarboxylic acids and aliphatic diamine with aromatic ring are through prepared by melt polycondensation, it in polyamide molecule main chain due to introducing fragrance
Ring, so as to improve heat resistance and mechanical property, reduces water absorption rate, is between general engineering plastic nylon and high temperature resistant engineering
Heat resistance between plastics PEEK resin high.Because semi-aromatic nylon is compared with nylon66 fiber, its maximum advantage is heat-resisting
The excellent and relatively low water absorption rate of property；Meanwhile, compared with all aromatic nylon, it has processing fluidity good, the spy being easily worked
Property.Therefore, as the need for the developing rapidly with environmental protection cause of new and high technology, its market demand is in rising trend, its application is opened
Hair also has new progress.
Polyphenylene oxide (abbreviation PPE or PPO) have good mechanical property, chemical stability, dielectric properties, heat resistance and
Anti-flammability, is a kind of high performance thermoplastic engineering plastic.First generation modified polyphenyl ether product is released since GE companies within 1966
Afterwards, polyphenylene oxide industry is developed rapidly, has become the fourth-largest engineering plastics after PA, PC, POM.Non-modified polyphenylene oxide
With good mechanical property, heat resistance, dimensional stability, chemical stability, hydrolytic resistance, high rigidity and anti-flammability etc.,
But PPO molecule chain rigiditys are larger, and notch shock is very sensitive, simultaneously because its melt viscosity higher, prevents it from being molded
Shaping, therefore significantly limit its application.
Because polyphenylene oxide is armorphous and nonpolar resin, nylon is crystal type and polar resin, while the two has breach
Sensitivity, the poor defect of impact property, therefore, how to produce one kind can either comprehensive polyphenylene oxide and semi-aromatic nylon each
Advantage can overcome the alloy material of the poor defect of the shock resistance of the two just to turn into problem demanding prompt solution again.
The content of the invention
First purpose of the invention is to provide a kind of high temperature resistant nylon/polyphenylene oxide composite material.
Second object of the present invention is to provide a kind of preparation method of above-mentioned high temperature resistant nylon/polyphenylene oxide composite material.
To reach above-mentioned purpose, solution of the invention is：
