Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0017] The invention discloses an ABS resin composition for electroplating and a preparation method thereof, which comprises a grafted ABS polymer with a weight percentage of 20-50% and a SAN copolymer with a weight percentage of 50-80%. The graft ratio of the grafted ABS polymer is 45%-75%, and the total amount of residual single and oligomer composed of styrene monomer and acrylonitrile monomer in the SAN copolymer is lower than 5000ppm.

[0018] The weight percentage of butadiene in the grafted...

Abstract

The invention discloses ABS resin composition for electroplating and a preparation method thereof. The electroplating ABS resin composition with excellent heat stability and electroplating practicability is prepared by controlling the grafting ratio of grafted ABS polymer, the total amount of oligomers and residual monomers in SAN copolymer and the vacuum degree during extrusion mixing, and the molding yield of electroplated products and the electroplating yield are substantially improved.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and in particular relates to an ABS resin composition for electroplating and a preparation method thereof. Background technique [0002] Plastic electroplating parts are widely used in interior and exterior decorative parts of automobiles, such as automobile signs, word marks, anti-scratch trims, radiator grilles, wheel covers, inner door handles, gear panels and so on. More than 90% of electroplated parts on the market use ABS or a blend of ABS as the electroplating substrate. With the increasingly fierce market competition, it is required to improve the molding yield and electroplating yield of plastic blanks. Therefore, higher requirements are put forward for the thermal stability and electroplatability of ABS materials. If the thermal stability of ABS is not good, the amount of smoke and smell will be large during injection molding, and silver wires, air marks, white fog, yellowing an...
