[0014] The invention provides a preparation method of a plastic product, comprising the following steps:
[0015] 1) Molding a plastic matrix; the plastic matrix is a thermoplastic or thermosetting plastic containing an electroless plating accelerator, and the electroless plating accelerator is uniformly distributed in the thermoplastic or thermosetting plastic; the electroless plating accelerator is a general formula ABO 3 The perovskite structure compound, wherein A contains at least one of the elements in the 9th, 10th, and 11th columns of the periodic table, and A selectively contains one or more of the elements of Groups IA, IIA and lanthanides; B It is one or more of the elements of Group IVB and VB;
[0016] 2) The surface of the plastic substrate is vaporized by laser, and the electroless plating accelerator is exposed;
[0017] 3) In step 2), electroless copper or electroless nickel plating is performed on the surface of the electroless plating accelerator, and at ...
Embodiment 1
[0049] (1) The CaCu 3 Ti 4 O 12 Put it into a high-speed ball mill, and mill it for 10 hours until the average particle size of the powder is 700 nm; the PPE / PPS resin alloy, CaCu 3 Ti 4 O 12 , calcium silicate fiber and antioxidant 1010, according to the mass ratio of 100:10:30:0.2, mixed with a high-mixer, extruded and granulated with a twin-screw extruder (Nanjing Rubber and Plastic Machinery Factory), and injection-molded into LEDs Lamp circuit board carrier.
[0050] (2) Using 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 , the power is 3W, and the filling spacing is 50 μm; after the laser irradiation is completed, the surface of the plastic carrier is ultrasonically cleaned.
[0051] (3) Immerse in the electroless nickel plating solution for 10 minutes to form a nickel layer with a thickness o...
Embodiment 2
[0054] Adopt the same method as Example 1 to prepare the plastic product of this example, the difference is:
[0055] In step (1), the CuNiTi 2 O 6 Ball milled to an average particle size of 800nm and dried; PEEK resin, CuNiTi 2 O 6 , glass fiber and antioxidant 168 are mixed in a mass ratio of 100:20:30:0.2, then extruded and pelletized and then injection-molded into an automotive engine electronic connector shell;
[0056] In step (3), the sequence of electroless plating is: first electroless nickel plating for 8 minutes to form a 2 μm thick nickel layer, then electroless copper plating for 3 hours to form a 13 μm thick copper layer, and then electroless nickel plating for 10 minutes to form a 3 μm thick nickel layer, Finally, a 0.03 μm thick gold layer was flash plated.
[0057] Through the above steps, the plastic product used as the housing of the electronic connector of the automobile engine of the present embodiment is obtained.
