Applicant it has been investigated that, triazine-based ultraviolet absorbent can absorb A areas and B areas ultraviolet light, volatility pole strongly
Low, light energy absorption can be converted into thermal energy by stabilised efficiency, benzotriazole light stabilizer, and molecular weight is larger, it is not easy to it is precipitated,
Stabilised efficiency；And cooperateed between triazine-based ultraviolet absorbent and benzotriazole light stabilizer and promote effect apparent, it is improving
While alloy material resistance to light, make material thermal stability and chemical resistance there has also been being obviously improved, while also promote
Into the promotion of alloy material mechanical performance.
In order to further take into account the mechanical performance of product and resistance to light, it is preferable that PC is the carefree PC-1150 of South Korea.
In order to further improve the thermal stability of alloy material and chemical resistance, it is preferable that PBT is middle Low viscosity resin, is sticked
It spends for 0.8-1 deciliter/grams.
Further preferably, PBT PBT-1100A.
In order to further improve the uniformity of alloy material and resistance to light, dispersant is methyl-silicone oil.
In order to further promote the synergistic effect between each component, and then further improve the light shine of alloy material
Can, while the mechanical property of alloy material is taken into account, antioxidant is that mass ratio is (1 ± 0.2)：The phenolic antioxidant of (1 ± 0.2) and
The mixture of phosphite antioxidant.
PC and PBT carries out transesterification in order to prevent, and ester exchange inhibitor is anhydrous sodium dihydrogen phosphate.
The preparation method of above-mentioned automobile using light shine PC/PBT alloy materials mixes raw material in high-speed mixer
Even, by double screw extruder extruding pelletization, drying, obtained pellet is molded into product through injection molding machine.
In order to further improve the homogeneity of material, first by PC, PBT and dispersant in the high speed that rotating speed is 250 ± 10rpm
5 ± 1min is mixed in mixer, then adds surplus material, 10 ± 1min is mixed in the case where rotating speed is 250 ± 10rpm, then passes through
Double screw extruder extruding pelletization, drying, obtained pellet are molded into product through injection molding machine.
In order to further improve the processing performance of material, during extruding pelletization, extrusion screw rod rotating speed is 310 ± 10rpm, temperature
For 250 ± 5 DEG C.
In order to further improve material later product moulding processability, temperature when dry is 100 ± 5 DEG C, the time 6
±0.5h；Injection temperature is 255 ± 5 DEG C.
It is obtained for true qualities without addition pigment in the application raw material, any color can be prepared as needed.
The unmentioned technology of the present invention is with reference to the prior art.
Automobile using light shine PC/PBT alloy materials of the present invention have good mechanical performance, thermal stability and chemically-resistant
Property, on the basis of ensureing that material has light shine, the color of product can be with various Sexual behavior mode；It prepares using one-step method work
Skill, it is simple to operation.
