Abstract

The invention relates to an electroplating poly carbonate (PC) / acrylonitrile butadiene styrene (ABS) alloy composition and a preparation method thereof. The PC and ABS alloy composition comprises the following components in part by weight: 30 to 80 parts of PC resin, 20 to 70 parts of ABS resin, 0.1 to 5 parts of carbon nano tube, 0.5 to 5 parts of compatilizer, 0.1 to 1 part of antioxidant, and 0.1 to 1 part of lubricating agent. The preparation method comprises the following steps of: adding all the components into a mixing and stirring machine in a ratio and mixing; and blending and pelletizing the obtained mixture by using a twin-screw extruder. The method is simple and feasible; due to the introducing of the compatilizer, the dispersing of the carbon nano tube in a PC / ABS base body is promoted; the PC / ABS alloy composition is endowed with excellent electric conduction performance by using a small amount of the carbon nano tube; and the alloy composition can be directly used for an electrocoppering process, the roughening, activating and chemical plating processes are eliminated, and an electroplating process is simplified.

Description

technical field [0001] The invention belongs to the fields of polymer blending and polymer molding processing, and in particular relates to an electroplating PC / ABS alloy composition and a preparation method thereof. Background technique [0002] PC / ABS alloy material has excellent electroplatability, and is widely used in interior and exterior parts of automobiles, such as interior and exterior door handles, automobile nameplates, wheel housings, grilles, decorative strips, etc. [0003] As an insulating material, PC / ABS usually needs to be treated to make it conductive in order to achieve electroplating. At present, the commonly used method is to roughen, activate, and electroless plating the PC / ABS alloy material to make its surface conductive, and then perform subsequent processes such as copper electroplating to achieve electroplating. [0004] Carbon nanotubes have excellent electrical conductivity. If they are added to the PC / ABS alloy material, the PC / ABS alloy mate...
