Abstract

The invention discloses an acrylonitrile-ethylene-styrene (AES) resin composition and a preparation method thereof. The composition comprises the following components in parts by weight: 10 to 50 parts of ethylene-propylene-diene monomer (EPDM) master batch, 50 to 90 parts of styrene-acrylonitrile (SAN) resin master batch, 0.02 to 0.2 part of initiator, 0.5 to 5 parts of co-crosslinker, and 0.3 to 1 part of antioxidant. The composition is prepared by adopting a reactive extrusion grafting method; and a compatilizer containing maleic anhydride (MAH) active functional groups, a compatilizer containing glycidyl methacrylate (GMA) active functional groups and modified EPDM and SAN resin are respectively prepared into the master batches, then other raw materials are added, the raw materials are stirred and mixed, and the mixture is extruded and granulated to form a sample. The reactive extrusion grafting method is environment-friendly, simple in equipment and convenient to operate; and the prepared composition has excellent weather resistance, low-temperature impact resistance, chemical corrosion resistance, size stability and processing performance, and can be applied to outdoor products such as building materials, sports equipment, communication equipment shells and automotive parts.

Description

technical field [0001] The invention relates to a resin composition and a preparation method thereof, in particular to an AES resin composition and a preparation method thereof for reactive extrusion grafting. Background technique [0002] AES resin is a copolymer formed by grafting acrylonitrile (AN) and styrene (ST) onto the main chain of ethylene propylene diene monomer (EPDM). Compared with general-purpose ABS resin, AES resin has similar basic physical properties, but because saturated EPDM rubber is used instead of unsaturated polybutadiene rubber, it has excellent weather resistance, low temperature impact resistance and Chemical corrosion resistance, which makes up for the performance defects of ABS resin, can be widely used in outdoor products such as building materials, sports equipment, communication equipment shells, auto parts, etc., and has a huge development space. It is a promising engineering plastic. . [0003] The graft copolymerization method of AES res...
