Problems solved by technology

However, due to the use of a mixture of various substances, the spray paint has only whiteness in the chroma of the color, but does not have the color effect of ceramic white, and the brightness of the color is low, so it cannot achieve the effect of ceramic white.
However, the method of coating can only achieve metallic silver white and bright gray

preparation example Construction

[0052] The preparation process of the first UV adhesive layer 140 includes: the pre-baking temperature is 50°C-60°C, the pre-baking time is 3min-5min; the humidity of the spray booth is 45%-70%, and the temperature of the spray booth is 18°C-25°C; The irradiation energy of the furnace is 900mj / cm 2 ~1200mj / cm 2 . The above only lists a commonly used UV adhesive layer preparation process, but is not limited thereto, and can also be a commonly used UV adhesive layer preparation process in the art.

[0053] Further, the thickness of the first UV adhesive layer 140 is 8 μm˜12 μm. In one embodiment, the thickness of the first UV adhesive layer 140 is 8 μm, 9 μm, 10 μm, 11 μm or 12 μm.

[0054] The function of the second UV adhesive layer 150 is mainly to protect the optical film layer 130 and improve the overall wear resistance of the middle frame 100 of the electronic product. The composition and preparation process of the second UV adhesive layer 150 are the same as those of ...

Embodiment 1

[0091] The manufacturing process of the middle frame of the electronic product in this embodiment is specifically as follows:

[0092] (1) Spray coating on the substrate to form a coating layer with a thickness of 15 μm. Wherein, the raw material of the paint layer is composed of paint main agent and 783 slow-drying water (thinner) with a mass ratio of 1:3. In parts by mass, the paint main agent is composed of 20 parts of ABS resin, 30 parts of titanium dioxide (white pigment), 30 parts of 783 slow-drying water (solvent) and 2 parts of dispersant (auxiliary).

[0093] (2) Forming a first UV adhesive layer with a thickness of 10 μm on the side of the coating layer away from the substrate. The raw material of the first UV adhesive layer consists of photoinitiator, auxiliary agent and 783 slow drying water (diluent).

[0094] (3) Sputtering sequentially on the side of the first UV glue layer away from the substrate to form a first high refractive index layer, a first low refrac...

Embodiment 2

[0097] The manufacturing process of the middle frame of the electronic product in Example 2 is similar to the manufacturing process of the middle frame of the electronic product in Example 1, except that the material and thickness of the optical film layer are different. In the optical film layer of embodiment 2, the material of the first high refractive index layer is TiO 2 , the thickness is 21nm, the material of the first low refractive index layer is SiO 2 , with a thickness of 28nm. The material of the second high refractive index layer is TiO 2 , with a thickness of 39nm.

Abstract

The invention relates to a middle frame of an electronic product, a manufacturing method of the middle frame, a shell of the electronic product and the electronic product. The middle frame of the electronic product comprises a base material, a coating layer arranged on the base material and an optical thin film layer arranged on the side, which is away from the base material, of the coating layer,wherein raw materials for preparing the coating layer comprise a coating main agent and a diluent, and the coating main agent comprises, by mass, 15-35 parts of resin, 20-40 parts of white pigment, 25-45 parts of a solvent and 1-6 parts of an auxiliary, the optical film layer comprises at least one high-refractive-index layer and at least one low-refractive-index layer, the high-refractive-indexlayers and the low-refractive-index layers are alternately arranged, the outermost layer, which is away from the base material, of the optical film layer is the high-refractive-index layer, and the Lab color chromaticity indexes of the middle frame of the electronic product are as follows: L ranges from 50 to 60, a ranges from -5 to 0, and b ranges from 0 to 5. The middle frame of the electronic product has a ceramic white appearance and is high in brightness.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a middle frame of an electronic product and a manufacturing method thereof, a casing of the electronic product and the electronic product. Background technique [0002] In the current decorative colors, ceramic white has always occupied a relatively large proportion, especially in electronic products, people prefer the appearance of white, and the proportion of white appearance accounts for almost half. Plastic and metal are generally used as the shell material of general electronic products, and spraying and oxidation are usually used to improve the appearance effect, but for electronic products such as mobile phones, if plastic is used, it will not be able to meet customer requirements in terms of performance and appearance. Most of them are glass, composite board, ceramics and other materials. These materials have good mechanical properties, and the appearance color is reali...
