Problems solved by technology

However, these paints usually contain toxic organic substances, causing environmental pollution and harming human health
In addition, due to the weak adhesion between the sprayed paint and the substrate of the electronic product, it is inevitable that the surface of the electronic product will be scratched during daily use, and the sprayed paint on the scratched part will fall off, thus making the appearance of the electronic product change. ugly

Embodiment Construction

[0012] The color coating provided by this technical solution and its manufacturing method will be further described below in conjunction with the drawings and embodiments.

[0013] See figure 1 , The color coating 100 provided in the first embodiment of the technical solution includes an adhesion layer 120, a color control layer 130, a reflective layer 140, and a corrosion-resistant layer 150 stacked in sequence.

[0014] The color coating 100 is formed on the outer surface 111 of the substrate 110. The base 110 may be a variety of products whose outer surface is to be colored, such as the housing of various electronic products. The base 110 may be made of various materials, such as glass, metal, ceramic, alloy, glass ceramic, and plastic. The plastic may be polycarbonate or polymethyl methacrylate or the like.

[0015] The material of the adhesion layer 120 is metallic chromium, and the thickness of the adhesion layer 120 is 0.3 to 10 nanometers, preferably 0.3 to 1.0 nanometers. I...

Abstract

The invention relates to a colored coating comprising an adhesive layer, a color control layer and a reflecting layer. The adhesive layer, the color control layer and the reflecting layer are sequentially stacked; the adhesive layer is made of chrome and formed on the surface of a substrate; the reflecting layer is made of aluminum and used for reflecting partial incident rays to form a first reflecting ray; the surface of the substrate reflects the rest incident rays to form a second reflecting ray; and the color control layer is made of silicon dioxide and used for controlling the optical path difference between the first reflecting ray and the second reflecting ray to enable the first reflecting ray to interfere with a second incident ray so that the colored coating presents different colors. The invention also relates to an electronic product using the colored coating.

Description

Technical field [0001] The invention relates to the field of surface coating, in particular to a color coating capable of forming multiple colors and an electronic product using the same. Background technique [0002] The surfaces of electronic products such as mobile phones, computers, and game consoles are usually painted in different colors to meet consumers' requirements for the appearance of the products. [0003] In the prior art, different colors are formed by spraying different colors of paint. Please refer to the literature Electrostaticpainting of insulating surfaces, Bouguila, N.; Coelho, R.; Navarre, D.; Industry Applications, IEEE Transactions on Volume 29, Issue 4, July-Aug. 1993 Page(s): 798-801. However, these paints usually contain toxic organic substances, causing environmental pollution and harming human health. In addition, due to the weak adhesion of the sprayed paint to the substrate of the electronic product, it is inevitable that the surface of the electro...
