preparation example Construction

[0027] see figure 1 , is a flow chart of the preparation method of the housing provided in an embodiment of the present application, including:

[0028] S101: Coating and baking a photocurable glue on the surface of the housing substrate.

[0029] S102: Provide a mold, the surface of the mold has lines, and cover the surface of the mold with lines on the light-curing adhesive to obtain a composite structure.

[0030] S103: Perform the first pressing and the second pressing of the composite structure, the pressure of the first pressing is lower than the pressure of the second pressing, and the pressure of the second pressing is greater than or equal to 48 MPa.

[0031] S104: The composite structure is cured and the mold is removed to obtain a shell.

[0032] In order to improve the appearance effect of the shell substrate, a textured layer structure can be formed on the shell substrate by means of transfer printing. When the existing transfer printing process is used for tran...

Embodiment 1

[0082] The photocurable adhesive includes 10% of 2-functional urethane acrylic resin, 8% of 6-functional urethane acrylic resin, 19% of 9-functional urethane acrylic resin, 1.5% of photoinitiator (TPO and photoinitiator 184), 1% of auxiliary agent And the balance of organic solvents (isobutanol, butyl acetate and propylene glycol methyl ether acetate). The light-curable glue is spray-coated on the surface of the polymethyl methacrylate plate with 3D structure, hung in the baking device, and baked at 65°C for 5 minutes, so that the solid content of the light-curable glue is about 38%.

[0083] Cover the surface of the light-curing adhesive with a textured mold, and place a silicone pad on the surface of the mold to obtain a composite structure; seal the composite structure with a polyethylene film and vacuumize it to 9.8Pa. After pressing for 30 seconds, place the composite structure under water pressure. The tank is pressed at 50Mpa for 50s.

[0084] The composite structure i...

Embodiment 2

[0087] It is roughly the same as Example 1, except that different templates are used, and the pressure of the first pressing is 15Pa, the pressing time is 25s, the pressure of the second pressing is 48MPa, and the pressing time is 55s, and the shell is obtained body. see Figure 12 , is a schematic diagram of the surface texture of the shell prepared in Example 2. It can be seen that the shell prepared in Example 2 has a snowflake texture through observation with a 200-fold optical magnification lens, which enriches the appearance of the shell.

Abstract

The invention provides a preparation method of a shell. The preparation method comprises the steps that the surface of a shell substrate is coated with light curing glue and baked; a mold is provided, the surface of the mold is provided with lines, the surface, provided with the lines, of the mold covers the photocuring glue, and a composite structure is obtained; the composite structure is subjected to first press fit and second press fit, the pressure of the first press fit is smaller than that of the second press fit, and the pressure of the second press fit is larger than or equal to 48 MPa; and the composite structure is subjected to curing treatment, the mold is removed, and the shell is obtained. The preparation method is simple and convenient to operate, and the lines on the surface of the mold can be clearly and completely transferred to the light-cured glue, so that the light-cured glue with the lines can be formed after curing, and the appearance effect of the shell is enriched. The invention further provides the shell and the electronic equipment.

Description

technical field [0001] The application belongs to the technical field of electronic products, and in particular relates to a casing, a preparation method thereof, and electronic equipment. Background technique [0002] With the continuous development of electronic equipment, users have higher and higher requirements on the appearance of electronic equipment, and the monotonous appearance can no longer meet the needs of users. Therefore, the appearance effects of more and more electronic devices are developing toward diversification. Contents of the invention [0003] In view of this, the present application provides a casing, a preparation method thereof, and an electronic device. [0004] In a first aspect, the present application provides a method for preparing a shell, including: [0005] Coating light-curing glue on the surface of the housing substrate and baking; [0006] A mold is provided, the surface of the mold has lines, and the surface of the mold with the li...
