1 embodiment product mechanical property of table compares
As shown in table 1, the shadow to alloy material mechanical performance with the base resin softening point of maleic anhydride grafting is illustrated
It rings.Embodiment 1-17 and comparative example 1-4 has chosen softening point respectively less than or equal to 85 DEG C and at least one softening point is more than 85 DEG C
The compatilizer of base resin, and the performance to alloy is made is tested.As can be seen that softening point is big from comparative example 1-4
In showing impact strength and tensile strength decline on alloy material prepared by 85 DEG C of compatilizers, mechanical property, material is adding
The problem of layering, decorative pattern being there is also during work.It, can compared to alloy material prepared by compatilizer of the softening point less than 85 DEG C
Meet the compatibility requirements of alloy system well, the mechanical property of material protrudes.
In conclusion the macromolecule Polycarbonate alloy material of the present invention, due to selecting the polyethylene of softening point≤85 DEG C
As grafting polymer, hence it is evident that improve the compatibility of PC and ABS, and the polyethylene comonomer therein of low softening point contains
It measures relatively high, on the premise of PC alloy materials other mechanical properties are not destroyed, significantly improves the impact strength of material.
In addition, special compatilizer addition manner and secondary granulation technique, preferably improve the compatibility of PC and ABS, reduce phase
Hold the dosage of agent.
The preparation method of the macromolecule Polycarbonate alloy material, hence it is evident that improve the compatibility of alloy system, make material
Expect that performance is more stablized, significantly improve the erosion-resisting characteristics of material, improve and there is layering sternly in actual processing process in which materials
There is the problem of decorative pattern in weight, surface.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
Various corresponding changes and deformation, but these corresponding changes and deformation can be made according to the present invention by knowing those skilled in the art
It should all belong to the scope of protection of the present invention.
