Abstract

The invention discloses a heat-resisting ABS modified material and a preparation method thereof for plating; the heat-resisting ABS modified material for plating is prepared by raw materials of acrylonitrile-butadiene-styrene copolymer (ABS), styrene-maleic anhydride copolymer (SMA), poly methyl methacrylate (PMMA), toughened rubber powder, antioxidant, a dispersing agent and other additives; the preparation method includes that: the raw materials are mixed and fed to a double-screw extruder for granulation, so as to obtain end products. The ABS modified material not only has high deformation temperature (HDT), but also has good plating effect, better impact toughness and flexural strength, and is applicable to parts requiring heat resistance and baking finish treatment.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a heat-resistant ABS modified material suitable for electroplating and a preparation method thereof. The invention not only has a high heat distortion temperature, but also has a good electroplating effect and good impact toughness, and can be applied to heat-resistant parts such as automobile lamps, hair dryers, coffee pots, and parts requiring baking treatment. Background technique [0002] Styrene-butadiene-acrylonitrile copolymer (ABS) is an engineering plastic with excellent comprehensive properties, but its heat resistance is insufficient, and its toughness and electroplating performance are also largely affected by the butadiene content in ABS raw materials. limit. While improving its heat resistance, the impact performance of ABS material is greatly reduced, and the two cannot be well coordinated. [0003] At present, there are mainly methods for improving the h...
