Embodiment Construction

[0033] Below in conjunction with embodiment, the present invention is described in further detail:

[0034]In the composite material formulations of Examples and Comparative Examples, the polycarbonate is bisphenol A type aromatic polycarbonate. In a preferred embodiment, the weight average molecular weight of the polycarbonate resin of the present invention is 10000-20000 g / mol, and the intrinsic viscosity is 0.3-1.5 deciliter per gram. In the composite material formulations of the examples and comparative examples, the PC resin produced by Dow Company of the United States is selected, and the brand is 201-15. Described styrene base resin is selected from ABS (acrylonitrile-butadiene-styrene copolymer), ASA (acrylate-styrene-acrylonitrile copolymer), SAN (styrene-acrylonitrile copolymer ), HIPS (High Impact Polystyrene) or their blends. In the composite material formulations of this example and the comparative example, the ABS high-glue powder produced by GE Company of the ...

Abstract

The invention discloses a polycarbonate / styryl resin composition which has light fastness and aging resistance and a preparation method thereof. The components and mixture ratio (weight proportion) of the composition are that: 50 percent-80 percent of polycarbonate, 10 percent-50 percent of styryl resin, 0.1-5 percent of molecular sieve, 0.1-1.0 percent of antioxidant 168, 0.1-1.0 percent of antioxidant 245, 0.1-2.0 percent of ultraviolet absorber, 0.1-2.0 percent of free radical quencher, etc. The resin composition prepared by the technical proposal of the invention can not only improve the anti-precipitation efficiency of light stabilizer in a composite material system to lead the prepared polycarbonate / styryl resin composition has better light fastness and aging resistance performance, but also has the advantage that all the physical mechanical performances and thermodynamic property of the material are basically not affected; furthermore, the method presented for improving the light fastness and aging resistance of polycarbonate / styryl resin composition has simple preparation technique and low production cost.

Description

technical field [0001] The invention relates to a polycarbonate / styrene-based resin composition resistant to light aging and a preparation method thereof, in particular to improving the stability of light-stabilizing additives in polycarbonate / styrene by adding a molecular sieve with adsorption effect. The anti-precipitation performance in the base resin composition, thereby improving the long-term light aging resistance performance of the polycarbonate / styrene-based resin composition, belongs to the field of polymer modification and processing. Background technique [0002] Polycarbonate and ABS composition has good heat resistance, high impact resistance and excellent processability. This alloy is widely used in auto parts, home appliances and electronic components. The ABS in the composition is synthesized from three chemical monomers of acrylonitrile, butadiene and styrene. Polymerization of the three monomers produces a terpolymer with two phases, a continuous phase o...
