The filling of above-mentioned height, high-impact, the preparation method of high durable PC-ABS composites, its step is：
(1) each raw material is weighed by proportioning；
(2) being well mixed by dry raw material, screw diameter 35mm, double spiral shells of draw ratio L/D=36 are subsequently placed in
In the main barrel of bar extruder, nine sections of control temperature of main barrel point；From charge door to head outlet be followed successively by 200 DEG C, 230 DEG C,
255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 240 DEG C, twin-screw rotating speed is 300 revs/min, and extrusion material strip is passed through
Pelletizing obtains product after tank cooling.
The plastic products that the PC-ABS composites obtained by the present invention program are made, with light-proofness high, high-impact, height
Weather-proof the advantages of, can be applied to the automobile interior exterior decorations product such as manufacture automobile instrument lamp box.
Specific embodiment
The invention will be further elucidated with reference to specific embodiments.It should be understood that these embodiments are merely to illustrate this hair
Bright rather than limitation the scope of the present invention.It should be further understood that after the content that the present invention tells about has been read, art technology
Personnel can change or change to the present invention, and these equivalent form of values equally fall within what the application appended claims were limited
Scope.
The embodiment of the present invention is raw materials used：
Polycarbonate：Molecular weight is 24000~27000 bisphenol a resin type resin, Samsung petro-chemical corporation of South Korea.
ABS：Continuous bulk synthetic resin, sinopec Shanghai Gaoqiao Petrochemical Company.
Compatilizer：Styrene-N- phenyl maleic acids imines-copolymer-maleic anhydride (SMI)：NEC chemistry, MS-
NA。
Toughener：Methyl methacrylate/butadiene/styrene copolymers (MBS), it is commercially available.
Titanium dioxide：R103, Dupont, it is commercially available.
Antioxidant 1010：Hinered phenols antioxidant, it is commercially available.
Irgasfos 168：Phosphoric acid ester antioxidant, it is commercially available.
UV 5411：Benzotriazole light absorber, Cytec companies of the U.S..
Properties of product method of testing：
Charpy notch impact strengths：By ISO 179-1 methods, size of sample：80*10*4mm.
Xenon lamp accelerated ageing：By SAE J2412 standards, energy value：600KJ/m2, measure aberration Δ E values.
Comparative example 1 and embodiment 1-5：
Institute's proportion of composing in pressing table 1 by dry PC, ABS, SMI, MBS, R103, the steady agent of light, antioxidant etc. is mixed
Through in double screw extruder (screw diameter 35mm, draw ratio L/D=36) main barrel, nine sections of main barrel point controls temperature after uniform
(being exported from charge door to head) is 200 DEG C, 230 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 240 DEG C,
Twin-screw rotating speed is 300 revs/min, and extrusion material strip obtains product by pelletizing after tank cooling.Needed after the completion of product pelletizing
Criticize mixed.By the said goods in the convection oven in after 95 DEG C of dryings 5 hours with plastic-injection moulding machine be molded into standard batten and
Standard tabula rasa (150*100*3.2mm), 250 DEG C of injection temperature.The batten and tabula rasa of injection formed are immediately placed in glass desicator
Performance and illumination test are carried out after room temperature is placed at least 24 hours.Test result is shown in Table 1.
The composition and performance of table 1PC-ABS compositions
It can be seen that being not added with the PC/ABS of titanium dioxide and light stabilizer from upper table comparative example 1 and embodiment 1-5
Weather resistance is significantly lower than addition titanium dioxide and the PC/ABS of light stabilizer, but being continuously increased with titanium white powder content, PC/
The toughness of ABS is presented downward trend but obvious toughness is still presented, and it is 20% that especially embodiment 5 works as titanium dioxide addition
When, Charpy notch impact strengths have reached 38.9KJ/m2, possess comparing toughness high, while PC/ABS of the invention has
Standby uvioresistant weather resistance higher, disclosure satisfy that by illumination accelerated ageing 600KJ/m2(J2412) chromatic aberration Δ E≤2
Rigors, but after titanium white powder content reaches 10%, illumination ageing performance increases trend and tends to balance.
It is contemplated that invention one kind has the advantages that filling high, high-impact, high durable PC/ABS composites, can be extensive
It is applied to the automobile interior exterior decorations product such as manufacture automobile instrument lamp box.
