preparation example Construction

[0032] Such as figure 1 Shown, the preparation method of the touch screen cover plate of an embodiment, comprises the following steps:

[0033] Step S110: forming a protective film in the middle of one surface of the substrate.

[0034] see figure 2 , figure 2 This is the substrate 200 on which no protective film has been formed.

[0035] Wherein, the substrate is a glass plate, a quartz plate, an alumina plate or a transparent organic plate.

[0036] The thickness of the substrate is 0.01-10 mm; preferably, the thickness of the substrate is 0.1-5 mm; more preferably, the thickness of the substrate is 0.3-2 mm.

[0037] see image 3 and Figure 4 , a protective film 300 is formed in the middle of one surface of the substrate 200 .

[0038] The material of the protective film can be peelable glue or soluble ink.

[0039] The soluble ink can be a water-soluble ink, and it can be understood that the soluble ink is not limited to a water-soluble ink, and any soluble ink ...

Embodiment 1

[0067] The preparation steps of the touch screen cover plate of the present embodiment are as follows:

[0068] (1) transfer peelable blue glue on the middle of one surface of a glass substrate with a thickness of 0.1 mm, and bake at 160° C. for 15 minutes to form a protective film.

[0069] (2) A nickel layer with a thickness of 10 nanometers is formed on the surface of the glass substrate not covered by the protective film by vacuum thermal evaporation, and the nickel layer surrounds the protective film.

[0070] (3) Tear off the protective film, screen-print thermosetting ink on the reflective layer, cure at 150° C. for 20 minutes to form an ink layer with a thickness of 1 mm, and then clean it to obtain a touch screen cover.

[0071] The reflectivity of the touch screen cover plate obtained in this embodiment is tested using a color inversion rate measuring instrument, and the glossiness of the touch screen cover plate obtained in this embodiment is tested using a standard...

Embodiment 2

[0073] The preparation steps of the touch screen cover plate of the present embodiment are as follows:

[0074] (1) Screen-print a water-soluble protective ink on the middle of one surface of a quartz substrate with a thickness of 5 mm, and bake at 150° C. for 15 minutes to form a protective film.

[0075] (2) The magnetron sputtering method is used to form a first silicon dioxide layer with a thickness of 30 nanometers, a first aluminum oxide layer with a thickness of 45 nanometers, a thickness of The second silicon dioxide layer is 45 nanometers, the second aluminum oxide layer is 50 nanometers thick, and the third silicon dioxide layer is 50 nanometers thick, that is, five reflective layers.

[0076] (3) Screen printing thermosetting ink on the third silicon dioxide layer, curing at 130° C. for 30 minutes to form an ink layer with a thickness of 1 nanometer.

[0077] (4) The substrate in step (3) is sprayed with pure water to remove the protective film, and then cleaned to...

Abstract

The invention relates to a manufacturing method for a touch screen cover plate. The manufacturing method for a touch screen cover plate comprises the following steps: forming a protection film on the middle part of a surface of a substrate; forming a reflecting layer on the position which is not covered by the protection film on the surface of the substrate, and the reflecting layer surrounding the protection film, the reflecting layer being a metal elemental layer, a metal alloy layer, a compound layer, or a silicon layer, the compound layer being one or more selected from an oxide layer, a fluoride layer, a zinc sulfide layer, a zinc selenide layer, a titanium nitride layer, a silicon carbide layer, a lanthanum titanate layer, a barium titanate layer, a strontium titanate layer, a praseodymium titanate layer, and a cadmium sulfide layer; removing the protection film; forming an ink layer on the reflecting layer, to obtain a touch screen cover plate. The ink layer can make light through the reflecting layer reflected back to the reflecting layer. The manufacturing method is simple in operation, and the manufactured touch screen cover plate has relatively good glossiness.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a method for preparing a touch screen cover. Background technique [0002] With the popularization of smart phones and tablet computers, the manufacturing process of touch screens (Touch Panel) has been continuously improved, and the capacitive touch screen cover has become the current mainstream. At present, the frame of the touch screen cover is mostly processed by silk screen printing ink, and the traditional black and white appearance can no longer satisfy consumers' pursuit of fashion. Various color frame mobile phones are gradually favored by the public. Although there are many colors of ink, due to the The gloss of the ink itself is dull, making the touch screen cover appear dull. Contents of the invention [0003] In view of this, it is necessary to provide a method for preparing a touch screen cover, which is relatively simple and capable of preparing a touch screen cover...
