[0041] 1 ) preparation>

[0042] The first copolymer component (A 1 ) is prepared by emulsification polymerization which contains 40% to 90% by weight of the first rubber emulsion (solid content) and 10% to 60% by weight of the first monomer component. The first monomer component includes 50% to 85% by weight of styrene monomer (i-1), 15% to 50% by weight of acrylonitrile monomer (i-2), and 0% by weight -35% by weight of other copolymerizable vinylic monomers (i-3). In this emulsion polymerization reaction, an emulsifier, a polymerization initiator, a chain transfer agent, etc. can be optionally added. After the emulsification polymerization reaction, it can optionally go through the steps of coagulation, dehydration and drying.

[0043] The first rubber emulsion is obtained by emulsion polymerization of the first rubber component, and after the emulsion polymerization, it is further treated with agglomeration (Agglomeration), and selectively added to other copolymerizable ...

Abstract

The invention provides a styrene-acrylonitrile- diene copolymer compound includes 5 to 40 parts by weight of copolymer mixture (A); 5 to 30 parts by weight of halogen fire retardant (B); 1 to 10 parts by weight of antimonial oxide (C); 0.2 to 2.5 parts by weight of di-methyltin mercaptide maleate polymer (D); 0.2 to 1.5 parts by weight of al-mg composite metal salt (E); and 60 to 95 parts by weight of vinyl benzene- acrylonitrile copolymer (F). The copolymer mixture (A) is formed by mixing first copolymer component (A1), second copolymer component (A2) and third copolymer component (A3). The vinyl benzene- acrylonitrile copolymer has good thermo-stability, low-temperature impact strength and flame retardancy.

Description

technical field [0001] The present invention relates to a kind of material suitable for the preparation of plastic molded products such as electrical equipment, office equipment, automobile parts, household goods, etc., particularly a kind of benzene containing dimethyl tin maleate polymer and aluminum-magnesium composite metal salt. Ethylene-acrylonitrile-diene copolymer composition. The present invention also provides a molded article formed from the composition. Background technique [0002] Generally, plastic moldings used for electrical equipment and household goods contain mostly rubber-modified styrene-based resins, polycarbonate resins, and the like. The rubber-modified styrene-based resin, such as styrene-acrylonitrile-butadiene-butadiene resin (ABS), has high surface hardness, good chemical resistance, good electrical properties and easy molding. characteristics, and gradually been widely used in various plastic molded products. [0003] However, when the rubber...
