Abstract
The invention discloses a plastic-based copper-chromium bilayer environment-friendly wearable electronic hardware fitting, wherein the matrix material of the electronic hardware fitting is plastic. The electronic hardware fitting is characterized in that a copper layer of 1-10 microns and a chromium layer of 0.5-3 microns are sequentially plated on the surface of the matrix from bottom to top. The plastic electronic hardware fitting disclosed by the invention contains no metal nickel and has high wearing resistance.
Description
Technical field
The invention belongs to electronics handware wear-proof technique field, relate in particular to the compound surface technology of copper-chromium metal level.
Background technology
All adopt plastics as base material at present a lot of electronic products, and compound multiple metal level improve its corrosion-resistant and wear resisting property on base material.Traditional mode is for adopting copper-nickel-chromium metal level, but the part human body is to nickel metal sensitivity, causes allergicly easily, therefore needs no nickelization.But preparation chromium metal level on the copper metal, technology is immature at present, and bonding force is poor between the two, and metal level grows dim easily.
Summary of the invention
Goal of the invention: at the problem and shortage of above-mentioned existing existence, the invention provides copper-wear-resisting electronics Hardware fitting of chromium double-layer environment protection of plastic base and preparation method thereof, this electronics Hardware fitting does not have nickelization, and has higher wear resistance.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: the wear-resisting electronics Hardware fitting of a kind of copper of plastic base-chromium double-layer environment protection, described electronics Hardware fitting body material is plastics, it is characterized in that: described matrix surface is coated with the chromium layer of 1～10 micron copper layer and 0.5～3 micron from bottom to up successively.
As preferably, described electronics Hardware fitting base material is ABS plastic.
Beneficial effect: compared with prior art, the present invention has the following advantages: plastic electronic Hardware fitting of the present invention nickel metal the time, does not have higher wear resistance.
Description of drawings
Fig. 1 is the structural representation of the wear-resisting electronics Hardware fitting of environmental protection of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, the matrix 1 of the electronics five metals workpiece of ABS base material forms electroless nickel layer through pre-treatment at workpiece earlier, electroplating little electric current then in cupric pyrophosphate electroplates, obtain 0.1～0.5 micron burnt copper coating, in copper-bath, electroplated 5 minutes then, obtain the sour copper coating about 4 microns, the thickness of copper layer 2 is about 4.5 microns in this process.After the citric acid solution through 50g/L carries out acid-wash activation, enter the sexavalent chrome plating bath and electroplate.
Wherein the prescription of sexavalent chrome plating bath is as follows: the Calucium Silicate powder of the chromic anhydride of 350g/L, the sulfuric acid of 1.5g/L, 5g/L, the cerium oxide of 1g/L and the Neodymium trioxide of 1g/L, and under 40～50 amperes/square decimeter electric current, electroplate 30～180s, can obtain 0.5～2 micron chromium coating 3.The hardness that obtains the chromium coating of workpiece is 620HV; Under 1000g pressure, rub back and forth through 1000 times rubbers, workpiece surface is not silvery white yet, does not see wearing and tearing.
The preferred specific embodiment of described the present invention only is used for the explanation embodiments of the present invention by reference to the accompanying drawings above; rather than as the restriction to aforementioned goal of the invention and claims content and scope; any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment all still belong to the technology of the present invention and rights protection category.
