Problems solved by technology

This method requires deplating, two times of vacuum coating, and two times of shielding protection. The process is cumbersome, and the two times of shielding protection are prone to inaccurate positioning, which makes it easy to appear zigzag patterns at the junction of the two color films, resulting in the fineness of the patterns. Poor, low yield

preparation example Construction

[0026] The preparation method of the above-mentioned coating member 10 mainly includes forming the first color layer 131 on the surface of the substrate 11 by vacuum coating and then forming the second color layer 133. The first color layer 131 and the second color layer 133 have different The color of the base material 11 is shielded and protected with a shielding object, so that the partial area of ​​the second color layer 133 is shielded; the substrate 11 treated with shielding is immersed in the stripping solution, so that the second color layer 133 is not shielded The part is removed to form an opening 135, so that the underlying first color layer 131 is partially exposed through the opening 135; the mask is removed, so that the surface of the film-coating member 10 presents two different colors.

[0027] The vacuum coating method may be a magnetron sputtering method.

[0028] Forming the first color layer 131 is under the condition of magnetron sputtering, with chromium ...

Embodiment

[0038] 1. Ultrasonic cleaning

[0039] The substrate 11 made of stainless steel (model 316L) was put into an ethanol solution for ultrasonic cleaning to remove impurities and oil stains on the surface of the substrate 11, and dried for later use after cleaning.

[0040] 2. Coating

[0041] Magnetron sputtering equipment (produced by Shenzhen Nanfang Innovation Vacuum Technology Co., Ltd., model SM-1100H. The magnetron sputtering equipment includes a vacuum chamber, a turntable, a magnetron target and a bias power supply. The magnetron target is a target structure , including a pair of chromium targets and a pair of titanium targets, a certain distance is formed between each pair of targets. The substrate is fixed on the turntable, and the turntable drives the substrate to pass between each pair of chromium targets when the turntable rotates.

[0042] Depositing the first color layer 131: adjust the temperature in the vacuum chamber to 150°C, feed argon gas into the vacuum cha...

Abstract

The invention provides a coated part which comprises a substrate and a coating film layer formed on the substrate. The coating film layer at least comprises a first color layer and a second color layer, the first color layer and the second color layer are of different colors, the first color layer is positioned between the substrate and the second color layer, a plurality of open holes are formed in the second color layer, the first color layer is partially exposed through the open holes, and the coated part is enabled to present two different colors. The invention further provides a preparation method of the coated part.

Description

technical field [0001] The invention relates to a coating part and a preparation method thereof, in particular to a two-color coating part and a preparation method thereof. Background technique [0002] At present, thin films are often coated on the surface of electronic products to achieve the purpose of surface decoration. In the prior art, multi-layer coatings are used, such as sputtering metal and metal oxide layers on the surface of the substrate, and the thickness of the metal oxide is controlled according to the principle of light interference. , Metallized substrates in various colors can be obtained. However, the substrate prepared by this method can only correspond to one color when the metal oxide layer on the surface is in a certain thickness range, and it is impossible to obtain a substrate with a two-color (two-color) surface at one time. [0003] In order to achieve a two-color effect on the surface of electronic products, vacuum coating is generally used fir...
