Embodiment 1

[0029] First, take a 0.05mm thick soda-calcium-silicon ultra-clear float glass substrate without defects and mildew, cut it into a certain size, clean and dry it, and then do the following:

[0030] A. Preparation of the pretreatment layer: After cleaning and drying the prepared glass substrate, place it in a 2 In the liquid reactor, let it stand still for 3 hours, then take it out, put it in a resistance furnace, heat it up to 450°C with the furnace, keep it warm for 1 hour, and form a pretreatment layer on the surface of the glass substrate; during this process, the temperature rise mainly has two functions. SOCl 2 Before the boiling point, appropriately raising the ambient temperature can improve the reactivity; in SOCl 2 Unreacted SOCl remaining on the glass surface after the boiling point 2 The decomposition is complete, and the traditional washing process is replaced by the method of decomposition. The heating up with the furnace is to prevent defects such as glass br...

Embodiment 2

[0034] First, take a 0.2mm thick soda-calcium-silicon ultra-clear float glass substrate without defects and mildew, cut it into a certain size, clean and dry it, and then do the following treatment:

[0035] A. Preparation of the pretreatment layer: After cleaning and drying the prepared glass substrate, place it in a 2 In the liquid reactor, let it stand for 5 hours, then take it out, put it in a resistance furnace, raise the temperature to 500°C with the furnace, keep it warm for 3 hours, and form a pretreatment layer on the surface of the glass substrate;

[0036] B. Preparation of ion-exchange layer: dry silver nitrate and potassium nitrate, mix evenly at a ratio of 10% silver nitrate and 90% potassium nitrate to obtain mixed nitrate, and then heat in an atmosphere furnace filled with dry nitrogen or air to 450°C, and then immerse the glass substrate treated in step A in the mixed nitrate at 450°C, and keep it warm for 10 hours to obtain the ion exchange layer;

Embodiment 3

[0039]First, take a 0.15mm thick soda-calcium-silicon ultra-clear float glass substrate without defects and mildew, cut it into a certain size, clean and dry it, and then do the following treatment:

[0040] A. Preparation of the pretreatment layer: After cleaning and drying the prepared glass substrate, place it in a 2 In the liquid reactor, let it stand for 4 hours, then take it out, put it in a resistance furnace, raise the temperature to 550°C with the furnace, keep it warm for 2 hours, and form a pretreatment layer on the surface of the glass substrate;

[0041] B. Preparation of ion-exchange layer: dry silver nitrate and potassium nitrate, mix uniformly at a ratio of 0.5% silver nitrate and 99.5% potassium nitrate to obtain mixed nitrate, and then heat in an atmosphere furnace filled with dry nitrogen or air to 400°C, and then immerse the glass substrate treated in step A in the mixed nitrate at 400°C, and keep it warm for 6 hours to obtain the ion exchange layer;

Abstract

A preparation method of a touch screen tempered glass film belongs to the technical field of tempered glass films of electronic products. The preparation method comprises the steps that a glass substrate and sticking glue are prepared, the lower surface of the glass substrate is stuck with the sticking glue to obtain the touch screen tempered glass film, and the preparation method further comprises the following steps that A, the prepared glass substrate is placed into a reactor filled with SOCl2 liquid after cleaned and dried, the reactor is stood for 3-5 h, the glass substrate is taken out and placed into a resistance furnace, the temperature of the glass substrate is raised to 450 DEG C to 550 DEG C with the furnace temperature, the temperature is kept for 1-3 h, and a pretreatment layer is formed on the surface of the glass substrate; B, the glass substrate treated by the step A is soaked in nitrate with the temperature of 330 DEG C to 550 DEG C, insulation treatment is performed for 2-10 h, and an ion exchange layer is obtained; C, the glass substrate treated by the step B and the sticking glue are combined so that the touch screen tempered glass film is obtained. The invention further discloses the touch screen tempered glass film prepared with the method, and the antibacterial effect of an antibacterial layer gathered on the surface of the tempered glass is better.

Description

technical field [0001] The invention belongs to the technical field of toughened glass film for electronic products, and relates to a tempered glass film for touch screen and a preparation method thereof. The tempered glass film for touch screen prepared by the method is an antibacterial layer of ion exchange method assembled on the surface of tempered glass, which is different from The existing coating method antibacterial layer combined separately on the glass has a better antibacterial effect, and there will be no shedding, separation and bacterial invasion caused by the combination. Background technique [0002] In recent years, touch devices such as mobile phones and tablet computers have pervaded all aspects of life. However, the growing touch technology brings convenience to people and also puts people at risk of spreading bacteria. Someone proposed to prepare an antibacterial layer on the touch screen to reduce the harm of people contacting bacteria. However, based ...
