Description
Technical field
The present invention relates to a kind of H.T. high mechanical strength polyphenylene sulfide alloy material and preparation method thereof, belonged to processing of high molecular material and modification technology field.
Background technology
Polyphenylene sulfide (PPS) is a kind of thermoplastic engineering plastic of half hitch crystal formation; Because it has high-mechanical property, high temperature resistant, chemical-resistant reagent, anti-irradiation, high from excellent properties such as fire-retardant, electrical isolation, dimensional stabilizing and antifatigues; Be called as first special engineering plastics, have a wide range of applications at industrial circles such as electronics, automobile, machinery, chemical industry.
The molecular weight of synthetic linear polyphenylene sulfide is lower in the industry, can't the direct plastication forming process, can only be used for spraying, thereby polyphenylene sulfide generally all to carry out the crosslinked of appropriateness, and carry out thermoplastic processing to improve its molecular weight.This lower molecular weight and the crosslinking structure of polyphenylene sulfide, it is crisp that the existence of molecular chain middle-high density phenyl ring causes this material matter in addition, limited its range of application.On the other hand, the said structure of polyphenylene sulfide and high processing temperature make that its melt strength is lower, are only applicable to injection moulding, and for extruding and blowing processing, can only carry out modification to it.
In order to improve the toughness of PPS, a lot of preparing methods are disclosed both at home and abroad.Chinese patent CN1462771A discloses the rubber toughened PPS material of nanometer butadiene-styrene-vinyl, but the toughness raising is limited; CN1186819A discloses the preparation of poly aromatic ether ketone/polyphenylene sulfide alloy material; Improved the mechanical property of alloy greatly; But owing to need under hot conditions, to carry out synthesizing and crosslinking reaction of polyimide on the PPS surface, the technology more complicated has considerable restraint to suitability for industrialized production.
U.S. Pat 4528346 discloses with the ternary of PPS, epoxy resin, other thermoplastic resin and strongthener or the matrix material of quaternary, has good mechanical property; US5625002 discloses the matrix material that specific PPS cooperates the polyolefin copolymer that contains epoxy group(ing); CN1300252C discloses the method that a kind of shell-and-core structure that uses the olefin copolymer that contains epoxide group and ethene and carbonatoms to form as 3-20 ethene or alpha-olefin copolymer comes Toughened PP S, has obtained all to have at high low temperature the alloy material of better shock strength; CN1718635A discloses a kind of H.T. that makes as impact modifying agent with styrene-ethylene/butylene-styrene (SEBS) three block elastomers or styrene-acrylonitrile copolymer acid butyl ester binary grafting ethylene-propylene rubber(EPR) and ethylene-methyl methacrylate Racemic glycidol ester blend and has filled and strengthen the PPS matrix material.But the not outstanding on the one hand explanation epoxide group of above-mentioned domestic and international patent plays conclusive compatible and chainextender effect in matrix material, and the toughness raising is very limited, and the stretching of gained material and shock strength all have substantial degradation; On the other hand, above-mentioned domestic and international patent is not made the research to the processing characteristics and the thermal property of matrix material yet, can not confirm and guarantee that stablizing of excellent properties that pure PPS resin is many is constant.
Summary of the invention
A kind of H.T. high mechanical strength polyphenylene sulfide alloy material that the objective of the invention is to be directed against the deficiency of prior art and provide; Be characterized in: first; Provide a kind of technology simple; Strong operability, the preparation method of a kind of H.T. high mechanical strength polyphenylene sulfide alloy material that can suitability for industrialized production; The second, the impelling strength and the physical strength of this alloy material all are greatly improved, and have increased the melt strength of alloy material simultaneously, can be applied to also be applicable to extrusion moulding, blow molding except that injection moulding, the spinning moulding, have enlarged the scope of application of processing.
The object of the invention is realized that by following technical scheme wherein said raw material umber is parts by weight except that specified otherwise.
The starting raw material of H.T. high mechanical strength polyphenylene sulfide alloy material is composed of the following components:
