preparation example Construction

[0022] The present invention also provides a method for preparing a plastic electroplating product, wherein the method includes the following steps in sequence:

[0023] A Apply a circle of insulating oil along the edge of the non-plating area of ​​the plastic part;

[0024] B chemically plate the plastic parts coated with insulating oil;

[0025] C electroplating the plastic parts after electroless plating;

[0026] D Remove the electroless plating layer of the non-plated area of ​​the plastic part after electroplating;

[0027] E Use bonding glue to bond the non-plated area of ​​the plastic part to the base material except for the electroless plating layer.

[0028] Electroless plating is to use a suitable reducing agent to selectively reduce and precipitate metal ions in the solution on the surface activated by the catalyst. The electroless plating layer in the present invention may be a plating layer obtained by reduction reaction of various metals known to those skille...

Embodiment 1

[0041] In this embodiment, the ABS plastic part 4*2*1cm is taken as an example, and the following treatments are performed on the ABS in sequence:

[0042] 1) Apply insulating oil

[0043] Apply a circle of insulating oil (Shenzhen Sanlixin Technology Co., Ltd. ABS Plastic Plating Insulating Oil SLG-100-20L / barrel-green) around the area that does not require electroplating on the ABS surface. The width of insulating oil is 0.4mm.

[0044] 2) degreasing

[0045] Put the ABS treated in step 1) in a degreasing solution of NaOH 50g / L for degreasing at a temperature of 60° C. for 4 min.

[0046] 3) coarsening

[0047] Put the ABS treated in step 2) in: sulfuric acid 400g / L, chromic anhydride 380g / L, Cr 3+ The roughening was carried out in 30g / L roughening solution, the roughening temperature was 70°C, and the roughening time was 15min.

[0048] 4) neutralize

[0049] Neutralize the roughened ABS with HCl 25g / L, the neutralization temperature is room temperature, and the time ...

Embodiment 2

[0071] Prepare plastic electroplating product according to the method for embodiment 1, difference is that electroless nickel plating is changed into electroless copper plating, and plating solution is 3.5g / L CuSO 4 ·5H 2 O, 35g / L sodium potassium tartrate, 7g / L NaOH, 3g / LNa 2 CO 3 , 1g / L NiCl 2 .6H 2 O, 5mL / L formaldehyde. The electroless plating temperature is 45° C., the electroless plating time is 8 minutes, the base material is polyethylene, and the prepared product is A2.

Abstract

The invention relates to a plastic electroplating product. The plastic electroplating product comprises a substrate and a plastic piece jointed to the substrate through a joint adhesive, wherein the surface of the plastic piece is divided into an electroplating area and at least one non-electroplating area, a circle of insulating oil is coated on the border of the non-electroplating area which comprises an area covered with the insulating oil and an insulating oil ring internal sealed area encircled by the insulating oil, a chemical electroplating layer and an electroplating layer sequentially cover the electroplating area, the chemical electroplating layer contacts with the plastic piece, and the joint adhesive is jointed with the non-electroplating area on the surface of the plastic piece. The invention also relates to the preparation method of the plastic electroplating product which has favorable bonding force and is widely used as spare parts of automobiles, motorcycles, household appliances and mobile phones.

Description

technical field [0001] The invention relates to a plastic electroplating product and a preparation method thereof. Background technique [0002] Plastic electroplating products are widely used in the production of parts of automobiles, motorcycles, household appliances, and mobile phones, such as door handles, trademarks, and reflectors, because they have the characteristics of light weight, easy molding, and beautiful appearance of metal plating. , steering wheel, mobile phone casing, buttons, etc. [0003] The electroplating process of plastic electroplating products is to form a thin conductive metal layer on the surface of the plastic parts through the electroless plating process in the pretreatment, and then attach the decorative and functional metals to the plastic through the electroplating process. The surface of the part, so that the plastic part has the appearance and performance of metal. Generally, plastic electroplating products only need to be electroplated w...
