According to the invention, the PBT/PA alloy is modified by a method of adding composite compatilizer into the PBT/PA alloy, thus, the defects of the PBT and the PA can be overcome and the advantages thereof can be combined, the rigidity and the strength of the alloy prepared with single compatilizer can be improved obviously, and the application range of the PBT and the PA is broadened greatly.
Description
Technical field
The present invention relates to a kind of PBT/PA Alloy And Preparation Method, especially relate to a kind of PBT/PA Alloy And Preparation Method of enhancing, belong to technical field of polymer materials.
Background technology
Polybutylene terephthalate (PBT) is a kind of crystallinity thermoplastic engineering materials that terephthalic acid and 1,4-butyleneglycol are polymerized.PBT is with its good electric property, mechanical property, thermotolerance, workability, be widely used in automobile, electronics, engineering and the daily life, but also have notch sensitivity, high notch shock is poor, high temperature rigid is poor and shortcoming such as toughness deficiency, has restricted the application of PBT.PA is the higher crystalline material of wetting ability, has excellent solvent resistance, easily processing, physical strength height, but its poor dimensional stability, thermotolerance are low.The PBT/PA alloy then combines both advantages, compensates its defect, and still also there is the shortcoming of consistency difference in high comprehensive performance, so need develops a kind of compatible reagent, strengthens its capacity and then improves its intensity.
Summary of the invention
For solving the deficiencies in the prior art, the objective of the invention is to overcome the defective of prior art, a kind of PBT/PA alloy of enhancing is provided.
Simultaneously, the present invention also provides a kind of preparation method of PBT/PA alloy of enhancing.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of PBT/PA alloy of enhancing is characterized in that, comprises that the parts by weight of following component and each component are:

The PBT/PA alloy of aforesaid a kind of enhancing is characterized in that, described oxidation inhibitor is a kind in antioxidant 1010, the oxidation inhibitor 168.
The PBT/PA alloy of aforesaid a kind of enhancing is characterized in that, described fire retardant is inorganic non-halogen fire retardant, can be a kind of in phosphorus system, phosphorus-nitrogen system, the phosphorus-silicon system.
The PBT/PA alloy of aforesaid a kind of enhancing is characterized in that, described static inhibitor is graphite or conductive carbon fibre.
A kind of preparation method of PBT/PA alloy of enhancing is characterized in that, may further comprise the steps:
(1) drying treatment: the PBT/PA alloy by the described a kind of enhancing of claim 1 takes by weighing each component, with PBT in air dry oven under 112 degree conditions dry 7 hours, PA under 90 degree conditions dry 5 hours, after the compound compatilizer arbitrary combination dry 4-6 hour.
(2) preparation Preblend: dry good component and other components that weighs up in the step (1) carried out pre-mixing.
(3) melt extrude granulation: with extruding pelletization in the Preblend feeding twin screw extruder of step (2) preparation, the temperature in each district of machine barrel is respectively: a district 210 degree, and two districts, 230 degree, three districts-five district is 235 degree.
(4) injection moulding machine injection moulding: with the pellet of gained in the step (3) under 90 degree conditions dry 12 hours, use the injection moulding machine injection moulding then, its barrel zone temperature condition is: a district 210 degree, and two districts, three districts: 230 spend, and injection pressure 50Mpa is spent in four districts 220.
Beneficial effect of the present invention is: the present invention by in the PBT/PA alloy, add compound compatilizer method to the in addition modification of PBT/PA alloy, can overcome the shortcoming of the two, comprehensive its advantage, can obviously improve rigidity and intensity when utilizing simple compatilizer, widen the range of application of the two greatly.
