Description
Technical field
The invention belongs to macromolecular material alloy field, more particularly, to a kind of Polyamide polyphenylether resin composition and its
Preparation method.
Background technology
Polyphenylene oxide (PPE) resin is one of five large-engineering plastics, with excellent heat resistance, dielectric properties, hydrolysis
Property and dimensional stability；And polyamide is also one of five large-engineering plastics, with excellent chemical-resistant and heat resistance,
But the poor dimensional stability of polyamide, water suction are extremely strong！Therefore, Polyamide polyphenylether resin composition has good heat-resisting
Property, dimensional stability, chemical solvent resistance and processing characteristics.
But, the poor compatibility of the polyamide of nonpolar polyphenylene oxide resin and polarity！Relevant polyamide polyphenylene oxide
The compatibilized research report of resin combination is a lot, the method for mainly making polyphenylene oxide sense dough or toughener sense dough.
The patent of such as CN 101225214 is first to prepare polyphenylene oxide resin and the horse of maleic anhydride grafting using the method for reactive extrursion
Compatilizer of the maleic anhydride grafted hydrogenated styrene-butadiene-styrene copolymer as Polyamide polyphenylether resin composition；
The patent of such as Publication No. CN102627851 is to introduce the compound containing NCO as compatilizer, improves both
Compatibility；Meanwhile, in order to obtain the Polyamide polyphenylether resin composition with good impact property, it usually needs add toughness reinforcing
Agent.The patent of such as Publication No. CN1117817 is the work(of the block copolymer and 1%-8% weight for introducing 1%-8% weight
Energy elastic polyolefin (EPDM- grafting-maleic anhydride) is prepared for the polyphenyl ether polyamide 66 of high impact and low injection ejecting force
Resin combination.The patent of Publication No. CN102627851 is also as anti-using block copolymer or function elastic polyolefin
Impact modifying agent, improves the impact property of polyphenylene oxide and polyamide.In above-mentioned prior art, Polyamide polyphenylether resin composition
Mobile performance and impact property tend not to have both, must improve containing for impact modifying agent to further improve impact property
Amount, thus sacrifices the mobile performance of alloy.
The content of the invention
The purpose of the present invention be exactly the defect in order to overcome above-mentioned prior art to exist and provide one kind have concurrently mobility and
Polyamide polyphenylether resin composition of impact property and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of Polyamide polyphenylether resin composition, is prepared using the raw material of following components and weight portion content：
The preferred following components of above-mentioned raw materials and weight portion content:Difunctional polyamide 40～60, simple function group polyamide
10～20, polyphenylene oxide 10～25, elastic block copolymer 5～10, function elastic polyolefin 1～5.
Described difunctional polyamide is the polyamide obtained by diamine and binary acid polycondensation, preferably polyamide
66。
Described simple function group polyamide is the polyamide obtained by lactams ring-opening polymerisation, preferably polyamide 6.
Described polyphenylene oxide is poly- (2,6- dimethyl-Isosorbide-5-Nitrae-phenylene) ether.
Described elastic block copolymer is SBS.
Described function elastic polyolefin is the ethylene-octene copolymer of maleic anhydride grafting.
The preparation method of Polyamide polyphenylether resin composition, using following steps：
(1) get the raw materials ready by formula；
(2) raw material is mixed in high-speed mixer, is thrown into double screw extruder, through frit reaction extrusion, granulation system
It is standby to obtain Polyamide polyphenylether resin composition.
The barrel temperature of described double screw extruder is set to 260-280 DEG C.
By the polyamide 66 compound use of the polyamide 6 of a small amount of simple function group and difunctional, then control elastomeric block and be total to
The ratio of polymers and function elastic polyolefin, not only can obtain the Polyamide polyphenylether resin composition of mobile performance improvement,
The impact property of composition also can be significantly increased.
For Polyamide polyphenylether resin composition, by the Amino End Group functional group in polyamide and function elastic polyolefin
In maleic groups there is chemical reaction, obtain good compatibility and interface adhesion so that the breach punching of composition
Hit intensity increases.Polyamide 66 is difunctional, and the two ends of some strands all have amino group, therefore, amino base
Group be likely to occur with the maleic groups in function elastic polyolefin contact twice, two secondary responses, frequently contact with instead
The phase size that composition should be caused is roughened；And polyamide 6 is simple function group, some molecular chain-end only one of which amino bases
At most only there is primary first-order equation in group, amino group, can be with sub-combination thing with the maleic groups in function elastic polyolefin
Phase size.
Compared with prior art, the Polyamide polyphenylether resin composition not only good flowing properties that prepared by the present invention, and and
The excellent impact property of tool, solves the difficult problem that processing characteristics and impact property can not get both in conventional art.Meanwhile, using this
Invention prepares the Polyamide polyphenylether resin composition of uniform impingement performance, and the consumption that can make toughener is greatly reduced, and combines
The cost of thing is reduced, and reduces the loss of polyphenylene oxide heat resistance and polyamide chemical-resistant.
