[0015] 1) Molded plastic matrix; the plastic matrix is ​​a thermoplastic or thermosetting plastic containing an electroless plating accelerator, and the electroless plating accelerator is evenly distributed in the thermoplastic or thermosetting plastic; the electroless plating accelerator is Ni 2 O 3 , Co 2 O 3 , CuSiO 3 , CuC 2 O 4 One or more of Cu / Fe / Mn or Cu / Fe / Al ternary co-sintered oxide, Cu / Fe / Al / Mn quaternary co-sintered oxide;

[0016] 2) Laser vaporizes the surface of the plastic substrate, exposing the electroless plating accelerator;

[0017] 3) In step 2), electroless copper or electroless nickel plating is performed on the surface of the electroless plating accelerator, and the electroless plating and / or electroplating is continued at least once to form a metal layer on the surface of the plastic substrate.

[0018] The inventors of the present invention found t...

Embodiment 1

[0047] (1) Put CuC 2 O 4 ·2H 2 O, vacuum drying to remove crystal water, ball milling to D50 below 1μm, dry; the PP resin, CuC 2 O 4 、Talc powder and antioxidant 1010 according to the mass ratio of 100:15:10:0.2 are mixed with a high mixer, and then extruded into a pipe with a single screw extruder (Nanjing Rubber and Plastic Machinery Factory), and the extrusion temperature is 180℃ .

[0048] (2) An infrared laser (Ted, DPF-M12) is used to irradiate the outer surface of the entire tube. The laser parameters are: wavelength 1064nm, scanning speed 1000mm / s, step length 9μm, delay 30μs, frequency 40KHz, power 3W, filling spacing 50μm; clean the surface of the pipe.

[0049] (3) Immerse in the electroless copper plating solution for 3 hours to form a copper layer with a thickness of 10μm, immerse in the electroless nickel plating solution for 10 minutes, and form a nickel layer with a thickness of 3μm outside the copper layer; electroless copper plating solution: CuSO 4 ·5H 2 O 0.12mo...

Embodiment 2

[0052] The plastic product of this embodiment is prepared by the same method as in embodiment 1, except that:

[0053] In step (1), the CuSiO 3 Ball mill to D50 of 2μm or less, dry; PC resin, CuSiO 3 , Antioxidant 168 and EVA wax are mixed according to the mass ratio of 100:20:0.2:0.1, then extruded and pelletized and then injection molded into the electrical shell;

Abstract

The invention provides a method for producing a plastic product and the plastic product. The production method comprises the following steps: 1) forming a plastic substrate, wherein the plastic substrate comprises a chemical plating enhancer which is one or more selected from Ni2O3, Co2O3, CuSiO3, CuC2O4, Cu/Fe/Mn or Cu/Fe/Al ternary co-sintering oxide, Cu/Fe/Al/Mn quaternary co-sintering oxide; 2) laser gasificating the surface of the plastic substrate, exposing the chemical plating enhancer; 3) performing chemical copper plating or chemical nickel plating, continuously carrying out a chemical plating and/or electroplating, forming a metal layer on the surface of the plastic substrate. The method of the invention has the advantages of simple process, low energy requirement and low cost; in addition, the chemical plating enhancer is distributed in the plastic substrate, thereby a plating layer formed by chemical plating has high binding force with the plastic substrate.

Description

[0001] Related application [0002] This application is a divisional application of a Chinese invention patent application with an application number of 200910238957.9, an application date of December 30, 2009, and an invention title of "a method for preparing a plastic product and a plastic product". Technical field [0003] 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 [0004] A metal layer is formed on the plastic surface as a path for electromagnetic signal transmission, which is widely used in automobiles, industry, computers, communications and other fields.
