Embodiment 1

[0024] A method for manufacturing a curved screen glass protective film, the specific steps are as follows:

[0025] Step 1: Cut and edge the 0.07mm thick glass into any mobile phone screen size we need;

[0026] Step 2, soaking the glass after edging in an acidic solution for 10 minutes, the acidic solution is a mixture of 12% hydrofluoric acid solution and 16% nitric acid solution with a mass fraction of 1:2.7;

[0027] Step 3, sweeping the surface of the soaked glass;

[0028] Step 4, electroplating a layer of thin film on the front of the glass after sweeping to obtain coated glass;

[0029] Step five, evenly apply silica gel on the reverse side of the coated glass (that is, the side without the coating film), and then dry it at low temperature to obtain a semi-finished product;

[0030] Step 6: Paste the bottom plate on the side of the semi-finished product coated with silica gel, and then perform degassing and leveling treatment of the silica gel to obtain the finished...

Embodiment 2

[0032] A method for manufacturing a curved screen glass protective film, the specific steps are as follows:

[0033] Step 1: Laser cut and edge the glass into any mobile phone screen size we need, and then punch holes;

[0034] Step 2, putting the glass after edging and drilling into an acidic solution and soaking for 10 minutes, the acidic solution is a mixture of hydrofluoric acid solution with a mass fraction of 13% and a nitric acid solution with a mass fraction of 18% in a mass ratio of 1:3.2 mixture;

[0035] Step 3, sweeping the surface of the soaked glass with a polishing carpet;

[0036] Step 4, electroplating a layer of thin film on the front of the glass after sweeping to obtain coated glass;

[0037] Step five, evenly apply silica gel on the reverse side of the coated glass (that is, the side without the coating film), and then dry it at low temperature to obtain a semi-finished product;

[0038] Step 6: Paste the bottom plate on the side of the semi-finished pr...

Embodiment 3

[0040] A method for manufacturing a curved screen glass protective film, the specific steps are as follows:

[0041] Step 1: Cut and edge the 0.07mm thick glass into any mobile phone screen size we need;

[0042] Step 2, soaking the glass after edging in an acidic solution for 15 minutes, the acidic solution is a mixture of 14% hydrofluoric acid solution and 20% nitric acid solution with a mass fraction of 1:3.6;

[0043] Step 3, sweeping the surface of the soaked glass;

[0044] Step 4, electroplating a layer of diamond-like carbon film on the front of the glass after sweeping, the thickness of the film is 0.03mm, to obtain coated glass;

[0045] Step 5: Apply silica gel evenly on the reverse side of the coated glass (that is, the side without the coating film), and then dry it at low temperature to obtain a semi-finished product, the thickness of which should not exceed 1mm;

[0046] Step 6: Paste the bottom plate on the side of the semi-finished product coated with silica...

Abstract

The invention discloses a manufacturing method of a curved screen glass protective film. The manufacturing method comprises the following specific steps: step 1, cutting glass and edging the glass into any mobile phone screen size required by people; 2, putting the edged glass into an acid solution, and soaking the glass for 10-15 minutes; 3, polishing the surface of the soaked glass; 4, electroplating a layer of film on the front surface of the polished glass to obtain coated glass; 5, uniformly smearing silica gel on the reverse side of the coated glass, and then performing drying at low temperature to obtain a semi-finished product; and step 6, pasting a bottom plate on the surface, coated with the silica gel, of the semi-finished product, and then carrying out silica gel defoaming andleveling treatment to obtain a finished product. The method is reasonable in step, the prepared finished product can be attached together along with use of the smart phone, the finished product can bebent and folded at will, the surface of the glass protective film has super-strong scratch resistance, the effect of protecting the flexible screen is perfectly achieved, and wide use prospects are achieved.

Description

technical field [0001] The invention relates to the field of protective film production, in particular to a method for producing a curved screen glass protective film. Background technique [0002] With the improvement of people's living standards and the increase of people's economic income, mobile phones have become an indispensable item for people's life, work and study. With the development of science and technology, smart phones are favored by people. A smart phone, like a personal computer, has an independent operating system and an independent operating space. Users can install software, games, navigation and other programs provided by third-party service providers by themselves, and can realize wireless network communication through mobile communication networks. The general term for accessing mobile phone types. [0003] Smart phones have brought convenience to people's life, work and entertainment, and the screens of smart phones are an important part of the smart...
