Abstract

The invention discloses a PEB-g-MAN toughening agent, a preparation method thereof and an engineering plastic ABMS. The invention discloses a method for preparing a PEB-g-MAN toughening agent by using a suspension grafting copolymerization method. The method comprises that: an ethylene-1-butylene copolymer is used as a grafting matrix, methyl methacrylate and vinyl cyanide are used as grafting monomers, and a PEB-g-MAN grafting copolymer of which PEB content is between 52.8 and 71.8 percent by weight is prepared by using suspension grafting copolymerization technology in the presence of an organic solvent. The monomer transformation rate of a grafting copolymer system reaches 80 to 95 percent. The synthesized PEB-g-MAN and SAN resin are mixed together to prepare the engineering plastic ABMS with excellent weather resistance, ageing resistance and yellowing resistance and high impact resistance, wherein the gap impact strength of the ABMS is between 10.5 and 63.1 kJ / m<2>.

Description

technical field

[0001] The invention relates to a method for synthesizing PEB-g-MAN and blending PEB-g-MAN with SAN resin to prepare high-impact engineering plastic ABMS with excellent weathering resistance and yellowing performance and high gloss. Background technique

[0002] AES is a high-impact engineering plastic with excellent resistance to weathering and yellowing. It is prepared by melt blending EPDM-g-SAN and SAN resin. AES engineering plastics are widely used in the manufacture of automobile and motorcycle accessories, fishing gear, fishing and agricultural turnover boxes, suitcases, etc. Due to its excellent weather resistance, it is also widely used in the manufacture of outdoor products such as housing exterior wall covers, doors and windows, billboards, and swimming pool decorative layers. AES engineering plastics technology has remarkable economic benefits, and has been industrialized on a large scale in the United States, Germany, Japan and other countries. ...
