preparation example Construction

[0014] The invention provides a kind of preparation method of plastic product, comprises the following steps:

[0015] 1) Forming a plastic substrate; the plastic substrate 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 oxides, Cu / Fe / Al / Mn quaternary co-sintered oxides;

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

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

[0018] The inventors of the presen...

Embodiment 1

[0047] (1) CuC 2 o 4 2H 2 O, vacuum drying to decrystallize water, ball milling until the D50 is below 1 μm, and drying; PP resin, CuC 2 o 4 , talcum powder and antioxidant 1010 are mixed at a mass ratio of 100:15:10:0.2 and then extruded into pipes with a single-screw extruder (Nanjing Rubber and Plastic Machinery Factory) at a temperature of 180°C .

[0048] (2) Use an infrared laser (Tide, DPF-M12) to irradiate the outer surface of the entire pipe. The laser parameters are: wavelength 1064nm, scanning speed 1000mm / s, step size 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 10 μm, and immerse in the electroless nickel plating solution for 10 minutes to form a nickel layer with a thickness of 3 μm on the outside of the copper layer; electroless copper plating solution: CuSO4 ·5H 2 O 0.12mol / L, Na 2 EDTA...

Embodiment 2

[0052] Adopt the method identical with embodiment 1 to prepare the plastic product of the present embodiment, difference is:

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

[0054] In step (2), the infrared laser is used to print the metal circuit pattern on the electrical casing; after the laser vaporization is completed, the electrical casing is ultrasonically cleaned;

[0055] In step (3), the sequence of electroless plating is: first electroless nickel plating for 10 minutes to form a 3 μm thick nickel layer, then electroless copper plating for 3 hours to form an 11 μm thick copper layer, and finally electroless nickel plating for 10 minutes to form a 3 μm thick nickel layer.

[0056] Through the above-mentioned steps, the plastic product used as an electric...

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
