Abstract
The invention relates to a high temperature-resistent low cost polyethylene terephthalate (PET)/polybutylene terephthalate (PBT) alloy material. The raw materials comprise 40-50% of PET, 1-7% of PBT, 8-15% of brominated polystyrene, 1-5% of antimony trioxide, 2-5% of toughening agent PTW, antioxidant 1010, antioxidant 168, 0.5-2% of PET nucleating agent P250, 0.3-1% of crystallization accelerating agent NA-95, 0.3-1% of crystallization accelerating agent P1000 and 25-35% of glass fiber. A preparation method provided by the invention is as follows: the raw materials except the glass fiber are blended and then added into a feeding hopper of a screw extruder; while the glass fiber is added into the screw extruder, and the raw materials are melt extruded and granulated to obtain the final product. The prepared product of the invention has good flexibility and fast crystallization rate, and also has the characteristics of high-temperature resistance and low cost.
Description
Technical field
The present invention relates to a kind of high temperature resistant low-cost PET/PBT alloy material and preparation method thereof, belong to technical field of polymer materials.
Background technology
PET (polyethylene terephthalate) has higher melt temperature and second-order transition temperature; It has antifatigue, crocking resistance is good; Ageing-resistant performance is excellent, the exsertile characteristics of electrical insulating property, but there is the shortcoming that crystallization velocity is slow, the mould molding temperature is high, shaping cycle is long again in it.
And polybutylene terephthalate; English name polybutylene terephthalate (being called for short PBT); It has the advantage that the molecule segment flexibility is good, mechanical property is good, heat-drawn wire is low, crystallization velocity is fast; But its price is than PET (polyethylene terephthalate) height, and its fusing point is lower than PET, accordingly its resistance toheat than PET a little less than.
Publication number is that the one Chinese patent application of CN1020408081A discloses a kind of " high gloss hangs down warp glass fiber REINFORCED PET/PBT Alloy And Preparation Method "; It is that PBT and PET are processed alloy material; Come comprehensive the two advantage, but in order to guarantee its snappiness and crystallization velocity preferably faster, wherein the usage quantity of PBT higher (content is at 15-60%); And the price of PBT will be higher than the price of PET far away; From making material cost high, in addition, its resistance toheat also remains further to be improved.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of high temperature resistant low-cost PET/PBT alloy material is provided, it had both had snappiness and crystallization velocity preferably faster, had the characteristics high temperature resistant, that cost is low simultaneously.
