Abstract

The invention provides a plastic product and a preparation method thereof. The method comprises the following steps: 1) forming a plastic base, wherein the plastic base contains chemically plated catalysts which are compounds shown in the formula I, II or III; 2) removing the plastics in the selected area on the surface of the plastic base and exposing the chemically plated catalysts in the corresponding area; and 3) chemically plating copper or nickel and continuing chemical plating and/or electroplating at least once to form a metal layer on the surface of the plastic base. The preparation method provided by the invention has the advantages of simple process, low requirement for energy and low cost. In addition, the chemically plated catalysts are distributed in the plastic base, so the plating layer formed after chemical plating and the plastic base have very high adhesion.

Description

technical field [0001] 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. Background technique [0002] A metal layer is formed on the surface of the plastic, which is used as a channel for electromagnetic signal transmission, and is widely used in automobiles, industries, computers, communications and other fields. The selective formation of a metal layer on the plastic surface is a core link in the manufacture of such plastic products. There are many methods for plastic surface metallization production lines. In the prior art, metal nuclei are first formed on the surface of the plastic substrate as the electroless plating catalytic active center, and then electroless plating is performed. [0003] For example, US2003031803A1 discloses the use of metal oxide particles such as ZnO, TiO 2 , ZrO 2 、Al 2 o 3 , CeO 2 It is coated on the surface ...
