Abstract

The invention discloses ACS (acrylonitrile-chlorinated polyethylene-styrene) resin composition and a method for preparing the same. The ACS resin composition comprise the following components in parts by weight: 30-60 parts of chlorinated polyethylene resin masterbatch, 40-70 parts of SAN (styrene acrylonitrile) resin masterbatch, 0.02-0.2 part of initiator, 0.5-5 parts of assistant cross-linking agent, 0.3-1 part of antioxidant and 0.5-1.5 pars of heat stabilizer. The ACS resin composition is prepared by adopting a method of grafting by reactive extrusion according to the following steps: preparing masterbatches respectively from a compatibilizer containing an MAH (maleic anhydride) active functional group, a compatibilizer containing a GMA (glycidyl methacrylate) active functional group, chlorinated polyethylene resin and SAN resin, adding other raw materials, stirring and mixing, and extruding and granulating to obtain a sample. The method of grafting through reactive extrusion is more environmental friendly, the equipment is simple, the process is more convenient to operate, and the prepared ACS resin composition has excellent weather resistance and good anti-static properties, dimensional stability and processing performance.

Description

technical field [0001] The invention relates to a resin composition and a preparation method thereof, in particular to an ACS resin composition and a preparation method thereof for reactive extrusion grafting. Background technique [0002] ACS resin is a copolymer formed by grafting acrylonitrile (AN) and styrene (ST) onto the main chain of chlorinated polyethylene (CPE). Compared with general-purpose ABS resin, ACS resin has similar basic physical properties, but because saturated chlorinated polyethylene rubber is used instead of unsaturated polybutadiene rubber, it has excellent weather resistance, inherent flame retardancy and Antistatic properties make up for the performance defects of ABS resin, and can be widely used in electronics, electrical appliances, communications, instruments, building materials, auto parts, and office machinery. It has a huge development space and is a promising engineering plastic. [0003] The graft copolymerization method of ACS resin can ...
