Abstract
The invention discloses a interpenetrating network compatilizer, using alkene, alpha alkene and octene copolymer in a total weight percent of 94-98.4% to react with a polar polymer in weight percent of 1.5-5% under the action of initiator in weight percent of 0.1-1% so as to obtain it. It has strong compatibility and its dosage is a little. The invention also discloses a heat- resistant, coldness-resistant and shock-resistant polyphenylene/nylon (PPE/PA) compound prepared by it and the corresponding preparing method. The compatilizer is applied in PPE/PA compound, largely reducing the losses of PPE heat resistance and PA glossiness, obtaining a PPE/PA alloy with excellent synthetic property and good surface glossiness.
Description
Technical field
The invention belongs to macromolecular material and machine-shaping field thereof, particularly a kind of have a cancellated compatilizer of IPN.The invention still further relates to heat-resisting, cold-resistant, the impact-resistant mixture made by this compatilizer and the preparation method of this mixture.
Background technology
Present domestic MODIFIED PP E seldom, and MODIFIED PP E adopts the PS modification, has only the GE company of the U.S. at present with the PPE of PA modification.The new expanding material that the said firm uses mainly is to adopt the polymeric means, promptly forms not only to have polarity but also have nonpolar segmented copolymer in polymerization process, or obtains having certain polar polymkeric substance with aliphatics or aromatic series fusion-grafting.This expanding material plays compatibilization between nonpolar PPE and polar PA, thereby make two complete incompatible polymers parts of PPE and PA compatible, but this polymerization and fusion-grafting be resulting, and to have certain polar expanding material be segmented copolymer or the grafting on molecule, the IPN reticulated structure can't be formed, thereby PPE and outstanding separately winter hardiness, thermotolerance and the chemical-resistant advantage of PA can not be given full play of.
Summary of the invention

Prepare the method for above-mentioned mixture, form by following steps:
(1) nylon and compatilizer mixing are through precision meter feeding twin screw extruder;
(2) treat that material in the forcing machine adds forcing machine through precision meter respectively with polyphenylene oxide and auxiliary agent after softening;
(3) extrusion temperature of control forcing machine through plasticizing, after the frit reaction, is extruded cooling, is dried up, pelletizing, metering, packing.
The length-to-diameter ratio of the twin screw extruder that uses is 24～36 among the preparation method, 2 or above precision meter and precise dose control device are arranged, each section of twin screw extruder barrel temperature should be controlled between 250～320 ℃, especially be 270～300 ℃, auxiliary agent is oxidation inhibitor, thermo-stabilizer, processing aid such as lubricant etc.
Beneficial effect of the present invention is:
Of the present invention cold-resistant, heat-resisting, shock-resistant PPE/PA mixture is a kind of cancellated mixture of IPN that has, the consumption of aggretion type expanding material that the amount ratio of polarity compatible agent in the PPE/PA mixture of this IPN reticulated structure mixture is above-mentioned and aliphatics or aromatic series fusion-grafting gained expanding material descends greatly, cancellated polarity compatible agent of IPN and nonpolar PPE are formed to be twined and compatible structure, and react with polarity PA molecule, form and both twined, the good high-performance engineering mixture of consistency that many structures of chemical bond are arranged again.Therefore loss can be significantly reduced, thereby all excellent PPE/PA alloy of over-all properties, surface gloss can be obtained PPE thermotolerance and PA glossiness.
