[0023] The method for treating a glass substrate of the present invention is further described below in conjunction with an embodiment, but the present invention is not limited thereby. The method of the present invention is intended to provide a method for treating a glass substrate, which is simple to operate and low in cost, can improve the heat dissipation performance of the glass, and at the same time improve the blue light protection and ultraviolet protection performance to meet the use needs of users.

[0024] Combination Figure 1 The method for processing a glass substrate of the present invention comprises the following steps:

[0025] forming a metal transition layer 11 on a glass substrate 10;

[0026] forming a scratch-resistant layer 13 on a first surface of the metal transition layer 11;

[0027] forming a first protective layer 15 on the anti-scratch layer 13;

[0028] forming a blue light ultraviolet layer 12 on a second surface of the metal transition layer 11 opposite to the first surface; and

[0029] A second protective layer 14 is formed on the blue ultraviolet layer 12 .

[0030] The present invention first forms a metal transition layer on a glass substrate, the metal transition layer has a heat dissipation function, thereby improving the heat protection and heat insulation effect of the glass, and sequentially forms an anti-scratch layer and a first protective layer on the metal transition layer, which can effectively improve the wear resistance and scratch resistance of the glass; on the other hand, a blue light ultraviolet layer is formed on the glass substrate to absorb blue light and ultraviolet rays, thereby improving the blue light protection and ultraviolet protection performance, and finally a second protective layer is formed on the outermost layer to further protect the glass.

[0031] Specifically, as an embodiment, the metal transition layer of the present invention is formed by ion sputtering. In a vacuum coating machine, a metal alloy is selected as a target material, and the metal alloy is bombarded by an electron gun of a sputtering coating machine to coat the surface of a glass substrate with the metal alloy. Preferably, the metal alloy is a chromium, nickel and titanium alloy. The prepared metal transition layer includes chromium, nickel and titanium, and more preferably, each metal weight includes 85 parts of chromium, 5 parts of nickel and 10 parts of titanium. As a preferred embodiment, the process conditions of ion sputtering are: the vacuum degree of the vacuum chamber is evacuated to 2×10 -3 Pa to 3×10 -3 Pa, fill with argon, the argon flow rate is maintained at 200sccm-300sccm, so that the vacuum degree of the vacuum chamber reaches 5Pa×10 -2 Pa, under the conditions of voltage of 2.5-3.0KV and current of 30-40A, argon gas is ionized and bombards the surface of the glass substrate for 10-15 minutes, forming a metal transition layer with a thickness of 5-6um, which wraps the outer surface of the glass substrate.

[0032] Then, a scratch-resistant layer is formed on the metal transition layer. Specifically, an epoxy acrylic resin prepared by toluene or butanone is coated on the metal transition layer.

[0033] Next, the raw material of the first protective layer, such as polyethylene material, is spread on the surface of the anti-scratch layer. The thickness of the first protective layer is 30-35um. It is cured for 30-40 minutes at a temperature of 75-80 degrees, so that the first protective layer and the anti-scratch layer are firmly bonded together.

[0034] Next, a blue light ultraviolet layer is formed on the second surface of the metal transition layer. As an embodiment, the blue light ultraviolet layer includes a blue light absorber, an ultraviolet shielding agent, and an adhesive. Specifically, the weight ratio of each component is 5% of the blue light absorber, 5% of the ultraviolet shielding agent, and the remaining 90% of the adhesive. After the three are mixed evenly, they are evenly coated on the other side of the metal transition layer, i.e., the second surface, with a thickness of 25-30um being preferred. As a preferred embodiment, the ultraviolet shielding agent includes a fluorescent brightener and a benzophenone-type ultraviolet absorber.

[0035] Finally, the raw material of the second protective layer, such as polyethylene material, is spread on the surface of the blue light ultraviolet layer. The thickness of the second protective layer is 40-50um. It is cured for 45-60 minutes at a temperature of 80 degrees, so that the second protective layer and the blue light ultraviolet layer are firmly bonded together.

[0036] Thus, the prepared glass film includes a metal transition layer, an anti-scratch layer, a blue light ultraviolet layer, and the first and second protective layers on the outer surfaces of both sides. The metal transition layer has a heat dissipation function, thereby improving the heat protection and heat insulation effect of the glass. The anti-scratch layer, the first protective layer, and the second protective layer can effectively improve the wear resistance and scratch resistance of the glass. The blue light ultraviolet layer can effectively absorb blue light and ultraviolet rays, thereby improving the blue light protection and ultraviolet protection performance. Moreover, the manufacturing method of the present invention is simple, low in cost, and easy to be promoted and used in industry.

[0037] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
