Background technology
At present, the most frequently used method for processing plastic surface is the metallization of frosting, and this method can give plastics how specific performance.And plastic electroplating technology has developed into a kind of valuable technology at nearly 30 years, because the bonding force of coating and matrix is good, etch resistant properties is stronger than take the coating that iron and steel is matrix, and heat-resisting, wear resisting property also can be improved, and therefore, applies more and more wider.
At present, conventional treatment process mainly contains: surperficial mechanical alligatoring, chemical roughen, sensitization, activation, electroless copper or chemical nickel plating, plating thick copper, electroplating bright copper, Bright Nickel Electroplating, electroplated decorative chromium etc.This has been plastic electroplating since 1962 drop into suitability for industrialized production, the processing method always generally adopting.Although this method comparison " maturation ", quality is not good enough, and first-time qualification rate is subject to the course of processing, and especially activation procedure operative technique has a strong impact on.
The object of activation is to make surface of plastic products form that one deck is uniform, continuous, " " center ", this precious metal that is gluey particulate have " induction " and act on when electroless copper or chemical nickel plating the catalysis that precious metal forms.But in existing production process, activation is proceed step by step, approximately altogether needs 29 procedures, therefore, be difficult to guarantee homogeneity and the continuity of this layer of catalytic center, very easily form the defect of chemical plating, and the treatment time is long, cost is high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the poling processing technique that a kind of engineering plastic surface is processed, can simplify treatment process, shorten the treatment time, cost-saving, improve surface smoothness, wear resistance and the intensity of engineering plastics simultaneously, make coating evenly, continuously, unanimously, difficult drop-off.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the poling processing technique that provides a kind of engineering plastic surface to process, comprise the steps: the engineering plastics through etch processes to immerse in activated solution and carry out activation treatment, described activated solution is colloidal pd activation solution, by first group of liquid and second group of liquid, mixed, wherein, described first group of liquid comprises following each component forming by quality: Palladous chloride 0.9-1.1g, tin protochloride 2.2-2.4g, distilled water 200mL, hydrochloric acid 100mL; Described second group of liquid comprises following each component forming by quality: tin protochloride 68-72g; Sodium stannate 7-8g, hydrochloric acid 200mL.
