Abstract

The invention discloses a deep-color heat-resistant ABS resin composition with improved weather resistance. The composition comprises the following components in parts by weight: 100 parts of acrylonitrile-butadiene-styrene resin, 1-5 parts of a heat resistant agent, 0.5-3.0 parts of an infrared reflection pigment, 0.1-1.0 part of titanium dioxide, 0.2-1.0 part of a light stabilizer and 0.5-2.0 parts of other auxiliary agents. The deep-color heat-resistant ABS resin composition with improved weather resistance is obtained by the steps of: fully stirring and mixing the raw materials in a high speed mixer; feeding the mixture into a twin-screw extruder through a metering device; melting and compounding the materials under conveyance, shearing and mixing of screws; and then performing extrusion, wire-bracing, cooling and dicing steps. The heat-resistant ABS resin composition disclosed by the invention not only has excellent weather resistance, but also has excellent mechanical properties, and is quite suitable for being applied to the field of automotive upholsteries.

Description

technical field [0001] The invention relates to the technical field of polymer materials, relates to a material suitable for automotive interior parts and a preparation method thereof, in particular to a dark heat-resistant ABS resin composition with improved weather resistance. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS) is an engineering plastic with excellent comprehensive properties such as high gloss, chemical corrosion resistance, high heat resistance, easy processing, and excellent dimensional stability. It has a wide range of applications in automobiles, household appliances, offices and other fields. Among them, heat-resistant ABS is the most common application in the automotive field, especially for automotive door panels, sub-dashboards, sun visors, cup holders, glove boxes, door handles and other interior parts that have certain requirements for heat resistance. In addition, heat-resistant ABS can also be used in exterior decor...
