Embodiment 1

[0023] The sample used is CR250 injection molded ABS sample.

[0024] 1. Wax removal and oil removal

[0025] Use commercially available or publicly available dewaxing fluids and degreasing fluids to dewax and degrease, rinse with a large amount of tap water, and then rinse with pure water. For example, you can use the universal wax removal water BCR and hot soak degreasing powder U-154 (DR) produced by Atotech Chemical Co., Ltd.

[0026] 2. Coarsening

[0027] Dissolve 30g of potassium permanganate in 500mL of pure aqueous solution to prepare liquid A; dissolve 20g of potassium persulfate and 50g of potassium molybdate in 300mL of pure water to prepare liquid B; slowly add liquid B to liquid A and add pure Water to 1 L is configured as a rough solution, the concentration of the potassium permanganate is 0.19 mol / L, the concentration of the potassium molybdate is 0.18 mol / L, and the concentration of potassium persulfate is 0.09 mol / L. The above-mentioned cleaned sample was ...

Embodiment 2

[0036] The sample that adopts is with embodiment 1.

[0037] Adopted degreasing, dewaxing, defilming, activation, electroless nickel plating method are the same as embodiment 1, the difference is the roughening method.

[0038] The roughening solution used in this example is: dissolving 25g of potassium permanganate in 500mL of pure aqueous solution to prepare liquid A; dissolving 25g of potassium persulfate and 80g of potassium molybdate in 300mL of pure water to prepare liquid B ; Add liquid B slowly to liquid A, add pure water to 1L to configure a coarsening solution, the concentration of the potassium permanganate is 0.16mol / L, the concentration of the potassium molybdate is 0.29mol / L, potassium persulfate The concentration is 0.12mol / L. The above-mentioned cleaned sample was immersed in the roughening solution at 50° C. for 5 minutes. The samples were then rinsed with tap water and washed with pure water.

[0039] Finally, an ABS sample attached with a light gray electro...

Embodiment 3

[0041] The sample that adopts is with embodiment 1.

[0042] Adopted degreasing, dewaxing, defilming, activation, electroless nickel plating method are the same as embodiment 1, the difference is the roughening method.

[0043] The roughening solution used in this example is: dissolving 20g of potassium permanganate in 500mL of pure aqueous solution to prepare liquid A; dissolving 20g of potassium persulfate and 80g of potassium molybdate in 300mL of pure water to prepare liquid B ; Add liquid B slowly to liquid A, add pure water to 1L to configure a coarsening solution, the concentration of the potassium permanganate is 0.13mol / L, the concentration of the potassium molybdate is 0.29mol / L, potassium persulfate The concentration is 0.09mol / L. The above-mentioned cleaned sample was immersed in the roughening solution at 20° C. for 15 minutes. The samples were then rinsed with tap water and washed with pure water.

Abstract

The invention provides a roughing solution which is a water solution containing potassium permanganate, persulfates and molybdates. The invention also provides a surface plating method for an acrylonitrile-butadiene-styrene terpolymer. The method is realized in a way that: on the surface of the acrylonitrile-butadiene-styrene terpolymer, deoiling, roughing, activating, chemical nickel plating and plating, wherein in the roughing step, the acrylonitrile-butadiene-styrene terpolymer is put in a roughing solution to carry out chemical roughing. In the ABS plastic plating technique, the roughing solution has favorable roughing effect, can enhance the adsorption capacity of colloid palladium after activation and improve the adhesive strength of the a plating layer and a substrate, and does not contain chromium, thereby reducing the environmental pollution, reducing the injuries to operating personnel and lowering the cost for waste liquid disposal.

Description

technical field [0001] The invention relates to a roughening solution and a surface electroplating method of an acrylonitrile-butadiene-styrene terpolymer, in particular to a roughening solution for acrylonitrile-butadiene-styrene terpolymer electroplating . Background technique [0002] ABS (Acrylonitrile-Butadiene-Styrene), the full name is acrylonitrile-butadiene-styrene terpolymer, its name code ABS is the combination of the first letters of the English names of these three monomers, in the copolymer A It forms a skeleton with the S component, and the B component is dispersed in this structure in a very fine spherical shape. This structure makes ABS an amorphous polymer material, non-toxic and tasteless, and has good electroplating performance, which is excellent. Non-metallic plating materials. After ABS is electroless nickel-plated, it not only maintains the light weight of the workpiece, but also endows it with metal conductivity, wear resistance, decoration and oth...
