preparation example Construction

[0012] The invention provides a kind of preparation method of plastic product, comprises the following steps:

[0013] 1) molding plastic substrate; the plastic substrate is a thermoplastic or thermosetting plastic containing a chemical plating catalyst precursor, and the chemical plating catalyst precursor is evenly distributed in thermoplastic or thermosetting plastic; the chemical plating catalyst precursor is copper, iron, zinc One or more of nitrides, borides or phosphides of tin, nitrides of tin, borides or phosphides of nickel;

[0014] 2) The laser is irradiated on a selected area on the surface of the plastic substrate, the surface plastic in the corresponding area is vaporized, and the exposed chemical plating catalyst precursor is decomposed to obtain the chemical plating catalyst;

[0015] 3) Electroless copper plating on the surface of the electroless plating catalyst obtained in step 2), continue to perform at least one electroless plating and / or electroplating, ...

Embodiment 1

[0046] (1) PP resin, Cu 3 B 2 , calcium silicate fiber and antioxidant 1010, according to the mass ratio of 100:10:30:0.2, mixed with a high mixer, extruded and pelletized with a twin-screw extruder (Nanjing Rubber and Plastic Machinery Factory), and injection molded into LED Lamp circuit board carrier.

[0047] (2) Use an infrared laser (Tide, DPF-M12) to print the metal circuit pattern on the LED lamp circuit board carrier. The laser parameters are: wavelength 1064nm, scanning speed 1000mm / s, step size 9μm, delay 30μs, frequency 40KHz , power 3W, filling pitch 50 μm; after the laser irradiation is completed, the surface of the plastic carrier is ultrasonically cleaned.

[0048] (3) immerse in the electroless copper plating solution for 4 hours to form a copper layer with a thickness of 15 μm; then immerse in the electroless nickel plating solution for 10 minutes to form a nickel layer with a thickness of 5 μm; finally flash-plate a 0.03 micron thick gold layer. Among them...

Embodiment 2

[0051] Adopt the method identical with embodiment 1 to prepare the plastic product of the present embodiment, difference is:

[0052] In step (1), the Fe 3 P ball milled to an average particle size of 800nm, dried; PEEK resin, Fe 3 P, glass fibers and antioxidant 168 are mixed in a mass ratio of 100:20:30:0.2, extruded and granulated and then injection molded to be an automobile engine electronic connector housing;

[0053] In step (3), the order of electroless plating is: first electroless copper plating for 4 hours to form a 15 μm thick copper layer, then electroless nickel plating for 10 minutes to form a 5 μm thick nickel layer, and finally flash plating a 0.03 μm thick gold layer.

[0054] Through the above steps, the plastic product used as the housing of the electronic connector of the automobile engine in this embodiment is obtained.

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 is a thermoplastic or thermosetting plastic containing chemically plated catalyst precursors which are uniformly distributed in the thermoplastic or thermosetting plastic; and the chemically plated catalyst precursors are one or more of nitrides, borides or phosphides of copper, iron and zinc, nitrides of tin and borides or phosphides of nickel; 2) using laser needles to irradiate the selected area on the surface of the plastic base, gasifying the surface plastics in the corresponding areas and decomposing the exposed chemically plated catalyst precursors to obtain a chemically plated catalyst; and 3) chemically plating copper on the surfaces of the chemically plated catalyst obtained in the step 2) 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 catalyst precursors 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 ...
