Embodiment Construction

[0032] Below in conjunction with embodiment, the present invention is described in further detail:

[0033] In the composite material formulations of the examples and comparative examples, the ABS matrix resin can be general-purpose ABS with different heat resistance and different impact resistance properties, and there are no strict requirements on the production company and variety. In industrial production, the rubber content is generally controlled to be 5-30% (weight fraction), the acrylonitrile content is 10-30% (weight fraction), and the styrene content is 40-70% (weight fraction). In this embodiment, the high-impact ABS produced by German BASF company, the brand name is GP22, and the high heat-resistant ABS produced by Korea LG company, the brand name is XR-409H. Antioxidant comprises that antioxidant 245 is produced by Ciba Company, and trade mark is Irganox 245, and chemical name is triethylene glycol bis-3-(3-tert-butyl-4-hydroxyl-5-methylphenyl) acrylonitrile; Ant...

Abstract

The invention relates to an acrylonitrile- butadiene- styrene ternary copolymer resin material (ABS) which has excellent resistance properties to sunlight and ageing. The components (weight percentage) are that: 100 percent of ABS, 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 preparation method is that: the compound which comprises the addition agents of the ABA, the molecular sieve, the antioxidant 168, the antioxidant 245, the ultraviolet absorber, the free radical quencher, etc. is uniformly mixed by a high-speed mixer at a high speed and then melted and extruded out by a double screw extruder for granulation. The method has the advantages of simple preparation technology, low manufacturing cost, excellent physical and chemical combination properties of the materials, excellent resistance properties to sunlight and ageing, etc.

Description

technical field [0001] The invention relates to a material for improving the long-term light aging resistance performance of acrylonitrile-butadiene-styrene terpolymer resin (ABS) materials and a preparation method thereof, especially to improve photostability by adding a molecular sieve with adsorption effect. The invention discloses anti-precipitation performance of additives in ABS materials, an ABS material with excellent light aging resistance and a preparation method thereof, belonging to the field of polymer modification and processing. Background technique [0002] Acrylonitrile-butadiene-styrene ternary copolymer resin, namely ABS (acrylnitrole-butadiene-styrene copolymer), is the most developed and changed variety among styrene series resins. Due to its super easy processability and appearance characteristics , low creep and excellent dimensional stability as well as high impact strength and relatively low price, compared with other resins, it has an indisputable a...
