Abstract

The invention discloses an acrylonitrile-chlorinated polyethylene-styrene resin composition and a preparation method of the acrylonitrile-chlorinated polyethylene-styrene resin composition. The composition comprises the following components in part by weight: 30 to 60 parts of acrylonitrile-chlorinated polyethylene-styrene grafting powder, 30 to 50 parts of SAN resin 1, 5 to 15 parts of weather resistance master batch, 0.3 to 3 parts of lubricant, 0.05 to 0.5 part of antioxidant and 0.5 to 1.5 parts of heat stabilizer. The composition is prepared by stirring and mixing the components except for the weather resistance master batch, adding the mixture from a main feed inlet of a double screw extrusion machine, adding the weather resistance master batch from a side feed inlet of the double screw extrusion machine and carrying out extrusion and granulation to obtain a sample. The obtained composition has excellent weather resistance, high low-temperature impact property and good antistatic property, size stability and processing property and is particularly suitable for the field of electrons, electrical appliances, communication, instruments, building materials, decorative materials,automobile parts and the like with high requirements on weather resistance, impact resistance and surface antistatic property.

Description

technical field [0001] The invention relates to a resin composition and a preparation method thereof, in particular to a highly weather-resistant acrylonitrile-chlorinated polyethylene-styrene resin composition and a preparation method thereof. Background technique [0002] Polybutadiene rubber is used in the synthesis of ABS resin, and the unsaturated carbon-carbon double bonds contained in it are easily broken by ultraviolet rays, which will easily cause yellowing and pulverization of ABS resin parts during use. , cracking and other phenomena. ABS resin cannot be directly used in outdoor products, and must undergo surface treatment methods such as spraying and electroplating to improve its weather resistance, but further surface treatment processes are not only time-consuming and laborious, but also cause serious environmental pollution. The application of high pollution processes such as spraying and electroplating will be limited, which requires solving the problem of p...
