Referring to fig. 1-4, an electroplating method for pearl nickel on an automobile grille comprises the following steps:
firstly, hanging an automobile grille and washing the automobile grille with water;
step two, carrying out acid removal treatment and water washing on the cleaned automobile grille;
step three, pre-roughening the automobile grille;
step four, washing the pre-roughened automobile grille;
fifthly, carrying out chromium-free roughening treatment on the automobile grille;

step seven, washing and soaking, and carrying out palladium activation treatment after soaking;
step eight, soaking and performing de-gelling treatment;
and step nine, washing with water and electroplating pearl nickel.
In the first step, an alkaline cleaning agent is used for washing the automobile grille, the purpose is to remove dirt and impurities on the surface of the automobile grille, and after preliminary washing, the automobile grille is subjected to acid removal treatment, which comprises the following specific steps: firstly degreasing an automobile grille by using an acid degreasing agent, aiming at removing grease and organic matters remained on the surface of the automobile grille, then putting the automobile grille into sulfuric acid solution for acid cleaning, removing oxides and impurities on the surface of metal, and washing with water again after acid cleaning to wash out the sulfuric acid solution.
In the electroplating of the pearl nickel on the automobile grille, the pre-roughening treatment is used for increasing the roughness of the metal surface and providing better surface adhesion and uniformity, and the sand blasting mode is adopted to carry out the sand blasting treatment on the automobile grille during the pre-roughening treatment, so that the aim of increasing the roughness of the surface of the automobile grille and providing better plating adhesion is achieved.
The main purpose of the water washing is to clean the metal surface after the pre-roughening treatment, and the roughening agent or other treating agent used in the pre-roughening process may remain on the metal surface, so that the residues can be effectively washed off by the water washing, and the cleanness and purity of the metal surface are ensured.
When the plating solution is used for coarsening the plastic parts, a permanganate solution mixture is used for coarsening the plastic parts, the permanganate solution mixture consists of 0.5% -2% of potassium permanganate, 10% -30% of sulfuric acid, 1% -5% of titanium dioxide and 63% -88.5% of water, a CRU machine is used for controlling the addition and maintenance of plating solution in the treatment process, the CRU machine is a device for automatically controlling and supplementing chemical agents and additives in the plating process, the CRU machine is connected with a plating bath, various parameters in the plating solution such as nickel ion concentration, acidity, temperature and stirring of the plating solution are monitored and controlled, when the parameters reach preset upper limit or lower limit, a proper amount of chemical agent or additive is automatically added into the plating solution by the CRU machine to keep the parameters within a specified range, the use of the CRU machine can improve the automation degree of the plating process, reduce manual intervention and errors, reduce the waste and cost of the chemical agents, monitor and adjust the plating solution in real time, ensure the stability of various components in the plating solution and proper quality of the plating layer are obtained when the plating solution is connected with the plating solution.
After chromium-free roughening, a reduction treatment is required, wherein the reduction treatment is a process of reducing oxides or other compounds generated on the surface of the metal into the metal by using a certain chemical reducing agent, and in the process, the reducing agent reacts with the surface of the metal to form a layer of reduction product, and the surface is reduced to a complete metal state so as to carry out subsequent electroplating treatment. In the invention, copper salt and citric acid are used as reducing agents, and a specific reaction equation is as follows:
Cu2++2e-→Cu
through the reaction, copper ions are reduced into metal copper, and a layer of reduction products of copper are generated on the metal surface, and the process can effectively remove oxides and other impurities on the metal surface, so that the metal surface becomes more active, and the subsequent electroplating treatment is facilitated.
Wherein the reduction reaction is carried out at room temperature, the temperature is 20-25 ℃, the PH value of the citric acid is 2-4, and the reduction reaction time is 10-30 minutes.
In the electroplating of the pearl nickel on the automobile grille, the metal surface is activated by using a palladium activation treatment mode, palladium activation refers to the use of palladium metal as an activating agent, and the purpose of the palladium activation is to enhance the activity of the metal surface, so that nickel ions in electroplating liquid are easier to adsorb and electroplate, and the activation process is usually carried out before electroplating, so that a good foundation is provided for subsequent electroplating.
After palladium activation, the automobile grille needs to be treated by de-colloid, and the method comprises the following steps: firstly, soaking the palladium-activated automobile grille in hot water at 50-70 ℃ for softening glue residues, then manually cleaning the automobile grille by using sponge to remove residual glue, and fully washing the automobile grille after de-gelling treatment to remove residual adhesive, glue and other impurities.
After the steps are finished, pearl nickel electroplating can be carried out on the automobile grille, firstly, plating solution which consists of 15% -25% of nickel salt, 65% -75% of acid plating solution, 1% -5% of additive and 1% -5% of dye is prepared, then the automobile grille is placed in an electroplating bath, nickel ions in the plating solution are deposited on the surface of the grille through electrolysis to form a uniform plating layer, and after the electroplating is finished, a post-treatment step is needed to improve the performance and the appearance of the plating layer: firstly, an acidic solution is used for cleaning the electroplated article, impurities possibly remaining on the surface and parts which do not form a reasonable structure are removed, then, sufficient water washing is carried out to remove the remaining electroplating solution and other impurities, and finally, the luster and the surface flatness of the plating layer are further improved through polishing, polishing and other methods.
Wherein the additive is polishing agent, film forming agent, maintaining agent and corrosion inhibitor.
According to the invention, the permanganate solution mixture is used for coarsening the plastic part, the chromic anhydride and sulfuric acid mixture which are relatively harmful in the prior art are replaced for etching the material, compared with the traditional electroplating grid, the hexavalent chromium electroplating process is realized, the harm to human bodies and the environmental pollution are reduced, the development direction of the current green industry is met, meanwhile, the color and luster of the pearl nickel are controlled by controlling the proportion of the additive and the dye, and the different requirements of each customer are met.
