Description
Technical field
The present invention relates to engineering plastics, particularly relate to a kind of polyphenylene oxide and polyethylene terephthalate blend and preparation method thereof.
Background technology
Polyphenylene oxide is called polyphenylene oxide or polyhenylene ether again, and chemical name is to gather 2,6-dimethyl-1, and the 4-phenylate, English name: Poly (phenylene oxide) deprecated, the abbreviation code name is PPO; Another English name: Poly (phenylene ether), the abbreviation code name is PPE, it is the resistant to elevated temperatures thermoplastic resin of a class, molecular chain contains a large amount of benzene ring structures and does not have strong polar group, have the physics of a series of excellences and mechanics, heat-resisting, fire-retardant, electrical insulation capability, its oxygen index OI is 29, belongs to self-extinguishing.But its second-order transition temperature height, melt fluidity is poor, therefore, generally on the market mainly is and other plastic blend modifications form engineering plastic alloy.Modified PolyphenyleneOxide) or MPPE (English name: Modified Polypheylene ether) the present the most typical engineering plastic alloy-MPPO (English name: with the consumption maximum in engineering plastics field for example, PPO and complete compatible polystyrene (English name: Polystyrene, the abbreviation code name is PS) the PPO/PS alloy that forms of blending and modifying, PPO and inconsistent polymeric amide (English name: Polyamide, the abbreviation code name is PA) the PPO/PA alloy that forms of blending and modifying, polyethylene terephthalate { English name: Poly (ethylene terephthalate), the PPO/PET alloy that the abbreviation code name forms for the PET} blending and modifying that PPO and consistency are very poor.Wherein prepare the PPO/PA alloy and need add the compatilizer that the polyolefine grafted contains epoxide group and acid anhydrides, could improve the consistency of co-mixing system, thereby improve its mechanical property.The water-intake rate of PPO/PA alloy is reduced to about 0.5%, and still than higher, the absorbed water influence of moisture absorption of size and rerum natura is bigger, can not be used for injection moulding large-scale precision goods; And the PPO/PET alloy not only the price of PET is more much lower than PA, preparation cost descends significantly, and water-intake rate is low to moderate about 0.05%, it is stable that size and rerum natura still can keep in wet environment, can be used for injection moulding large-scale precision goods, but, need add compatilizer when PPO and PET blend, to increase the consistency of PPO and PET.Generally the first functionalized PPO of preparation before the preparation blend promptly carries out chemical modification to PPO, make its with go up can with carboxyl, amino, hydroxyl or the ester group etc. of PET end group reaction, react with the good PET of consistency again and make blend.But, prepare the operation more complicated of functionalized PPO, and be difficult to control.

The performance perameter of embodiment 1～8 product testing in the contrast table 2 has to draw a conclusion:
1) fire-retardant PPO and the PET blend high comprehensive performance of enhancing, and water-intake rate is low to moderate 0.05%, and fire resistance reaches the fire-retardant index of UL94 V0 level.When the proportioning of PPO and PET is 1: when (1～1.5), the over-all properties of blend is relatively good, and along with the increase of PET content, the system shock strength increases, and flexural strength and modulus reduce;
2) compatilizer SEBS-g-GMA can provide high impulse strength to system, and compatilizer PS-g-GMA can provide higher flexural strength and modulus in flexure to system, but simultaneously impact strength decreased is a lot, and tensile strength both are close; Not just as compatilizer, unnecessary graft copolymer also improves the toughness of system to the graft copolymer that adds as toughner in system.Compatilizer SEBS-g-GMA contains elastomerics SEBS, and its toughening effect is better than compatilizer PS-g-GMA, considers from over-all properties, strengthens fire-retardant PPO and PET blend and selects compatilizer SEBS-g-GMA better;
3) adding 2% length-to-diameter ratio in the system is 10～25 the talcum powder with laminate structure, can improve the flame retardant properties of system, making originally, the sample of fire resistance V1 becomes V0, but, talcous flame retarding efficiency only helps out not as good as the fire retardant height, and adds the talcum powder with laminate structure and can reduce shock strength by a small margin, increase flexural strength and modulus in flexure slightly, tensile strength then changes not quite.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, make some being equal to without departing from the inventive concept of the premise to substitute or obvious modification, and performance or purposes are identical, all should be considered as belonging to protection scope of the present invention.
