Abstract

The invention provides a preparation method of a plastic product and a plastic product. The method comprises steps of: 1) moulding a plastic matrix containing a chemical plating catalyst compound with a formula III; 2) removing plastic on a selected zone of the plastic matrix and exposing the chemical plating catalyst on a corresponding zone; 3) carrying out chemical copper facing or chemical nickel plating, continuing to carry out at least one time of chemical plating and / or electroplate to form a metal level on the plastic matrix surface. The preparation method provided by the invention has simple technology, low energy demand and low cost; besides, the chemical plating catalyst is distributed into the plastic matrix, so the coating formed after chemical plating has quite high bondingforce with the plastic matrix.

Description

[0001] This application is a divisional application with the applicant being BYD Co., Ltd., the filing date is August 19, 2010, the application number is 201010260236.0, and the invention title is "a preparation method of a plastic product and a plastic product". technical field [0002] The invention belongs to the field of surface metallization of non-metallic materials, and in particular relates to a preparation method of a plastic product and a plastic product.
