Detailed Description
The utility model discloses a car light face guard, including the face guard body, its characterized in that: the mask body is formed by combining a light-transmitting material part 2 and an electroplating substrate part 1 which are molded into a whole by multicolor injection; the surface of the electroplating substrate part 1 is provided with an electroplated layer 3, and the outer side surfaces of the electroplated layer 3 and the light-transmitting material part 2 are provided with a varnish layer 4.
As the utility model discloses an optimal selection scheme of car lamp face guard, 2 surface spraying priming paint layers in plating layer 3 and printing opacity material portion, the spraying of clear coat layer 4 is in priming paint layer surface.
As the utility model discloses another kind of preferred scheme of car lamp face guard, the printing opacity material portion 2 of face guard body inlays in electroplating base material portion 1.
As the third preferred scheme of the car lamp face guard of the utility model, the printing opacity material portion 2 is PC or PC + diffusant, the electroplating substrate portion 1 is ABS or PC + ABS.
The utility model discloses above-mentioned production technology of car lamp face guard, including following step: step A, multi-color injection molding to form a mask body; step B, an electroplating process, namely electroplating the surface of the mask body to generate an electroplated layer on the surface of the electroplating base material, wherein the electroplated layer cannot be formed on the surface of the light-transmitting material; step C, spraying varnish on the electroplated mask body; and D, performing plasma activation treatment on the surface of the electroplated layer between the step B and the step C.
The step B, the electroplating process comprises the following steps: ultrasonic degreasing → coarsening → neutralization → presoaking → palladium activation → double-sided glue → chemical nickel → acid activation → nickel preplating → acid activation → copper plating, nickel or chromium → drying.
Wherein, the palladium activation uses low-activity palladium as an activating agent IN, common active palladium as an activating agent SF, and the concentration is controlled as follows: pd: 10-60 ppm; sn (tin) 2+ : 1-6 g/l; HCI:230 to 350ml/l; the temperature is controlled at 18-30 ℃, and the activation time is 0.5-5 min.
The double-degumming process comprises the following steps: firstly, 1-15 g/l of NaOH is used for carrying out alkali degumming treatment on a workpiece for 1-5 minutes at room temperature; then, mild accelerator PLUS, 100-200 ml/l, is used for carrying out acid degumming treatment on the workpiece for 1-5 minutes at the temperature of 40-50 ℃.
