Embodiment 1

[0042] Carry out partial vacuum electroplating with protective oil of the present invention, concrete implementation steps are as follows;

[0043] (1) Preparation of coating protection oil

[0044] Take 40g of phenylmethyl silicone resin, add 10g of butyl acetate to it, and stir until it is evenly mixed; then add 40g of titanium dioxide, stir for 30 minutes to disperse the titanium dioxide evenly; finally add 1g of dibutyl phthalate, and stir until Mix evenly to obtain coating protection oil.

[0045] (2) Apply protective oil

[0046] Take pictures of the untreated plated parts, such as figure 1Shown in (a). Use a brush to dip the coating protection oil and apply it evenly on the parts that need to be protected, and let it stand for 30 minutes to make the protective oil form a film. Put the coating into the oven, set the temperature to 140°C, take it out after curing for 30 minutes, and place it for recovery to room temperature, take pictures and save, such as figure 1 S...

Embodiment 2

[0052] Realize two-color vacuum electroplating with protective oil of the present invention, concrete implementation steps are as follows;

[0053] (1) Preparation of coating protection oil

[0054] Take 50g of phenylmethyl silicone resin, add 15g of butyl acetate into it, stir until it is evenly mixed; then add 25g of titanium dioxide, stir for 30 minutes to disperse the titanium dioxide; finally add 1g of dibutyl phthalate and 0.5g 2,4-di-tert-butylphenol, stirred until uniformly mixed to obtain coating protection oil.

[0055] (2) The first layer of vacuum plating

[0056] Take pictures of the untreated plated parts, such as figure 2 Shown in (a). Vacuum electroplate a black metal film layer on the plated parts in an environment of 250 °C, return to room temperature after electroplating, and take pictures for storage, such as figure 2 As shown in (b), the plated part is coated with a black metal film layer.

[0057] (3) Apply protective oil

[0058] Dip the coating ...

Abstract

The invention provides a coating protection oil and a using method thereof, belonging to the technical field of vacuum electroplating. The coating protection oil of the present invention is made up of silicone resin, pigment and filler, plasticizer, diluent, and its use method comprises the following steps: (1) evenly smear coating protection oil on the plated piece; (2) apply coating protection oil (3) carry out vacuum electroplating; (4) wash away protective oil; electroplating protective oil of the present invention can protect the position that does not need to coat film layer in vacuum electroplating, and operation is simple and convenient, and position selection is flexible, meets Plated parts have a good application prospect for partial coating and multi-color coating.

Description

technical field [0001] The invention belongs to the technical field of vacuum electroplating, and in particular relates to a coating protection oil and a using method thereof. Background technique [0002] Vacuum electroplating, also known as vacuum coating, is a physical deposition phenomenon, that is, under vacuum conditions, using low-voltage, high-current arc discharge technology, using gas discharge to evaporate the target material and ionize the evaporated material, and then use The action of the electric field makes the evaporated substance or its reaction product deposit on the workpiece to form a uniform and smooth surface layer. The products made by vacuum coating have strong metallic feeling and high brightness. Compared with electroless plating, electroforming and other coating methods, the cost is lower, and the pollution to the environment is small. At the same time, it can improve product quality and prolong product life. It has a very good market. prospect. ...
