preparation example Construction

[0016] According to one embodiment of the present invention, the present invention provides a kind of preparation method of plastic product, comprises the following steps:

[0017] 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;

[0018] 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;

[0019] 3) Electroless copper plating on the surface of the electroless plating catalyst obtained in step 2), continue to pe...

Embodiment 1

[0050] (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.

[0051] (2) Use an infrared laser (Tide, DPF-M12) to print metal circuit patterns 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.

[0052] (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, e...

Embodiment 2

[0055]Adopt the method identical with embodiment 1 to prepare the plastic product of the present embodiment, difference is:

[0056] 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;

[0057] 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.

[0058] 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 discloses a preparation method for plastic products and a plastic product. The method comprises the following steps: 1) forming a plastic matrix, wherein, the plastic matrix is thermoplastic or thermosetting plastic containing chemical plating catalyst precursors which are uniformly distributed in the thermoplastic or thermosetting plastic and are one or more selected from the group consisting of nitrides, borides or phosphides of copper, iron and zinc, nitrides of tin and borides or phosphides of nickel; 2) irradiating a selected area on the surface of the plastic matrix with a laser needle and decomposing exposed chemical plating catalyst precursors to obtain a chemical plating catalyst; 3) carrying out chemical copper plating on the surface of the chemical plating catalyst obtained in step 2) and carrying out at least one more chemical plating and / or electroplating so as to form a metal layer on the surface of the plastic matrix. The preparation method provided in the invention has the advantages of a simple process and low requirements on energy. Furthermore, the bonding force between a coating formed after chemical plating and the plastic matrix is fairly high.

Description

[0001] This application is a divisional application of an invention patent application with the application number 201010155293.2 and the title of the invention "a method for preparing a plastic product and a plastic product" submitted on April 14, 2010. 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. Background technique [0003] 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 substra...
