In the description of the present invention, reference to the description of the terms "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Because 3A glass is in order to reach anti-dazzle effect when producing, the surface of 3A glass can be through special processing for the reflection of light surface of 3A glass becomes the matte surface, thereby reduces the reflection of light, reaches the purpose that does not dazzle.

Wherein, in the matte treatment process of the surface of the 3A glass, the surface of the 3A glass can be processed into an uneven plane, so that the abrasion resistance of the surface of the 3A glass is poor. In order to solve the above problems, the applicant of the present application has proposed a method for producing 3A glass.

Further, referring to fig. 1, in some embodiments, the method for manufacturing the 3A glass includes the steps of:

s100, forming an AG layer on the glass substrate;

s200, polishing the AG layer;

s300, forming an AR layer on the polished AG layer;

s400, forming an AF layer on the AR layer.

The Anti-Glare (Anti-Glare) layer can play an Anti-Glare effect, the polishing can adopt a chemical polishing mode and a physical polishing mode, the AR (Anti-Reflection) layer can play an Anti-Reflection effect, and the AF (Anti-Fingerprint) layer can play an Anti-Fingerprint effect.

Specifically, referring to fig. 2 and 3, after the AG layer is formed on the glass substrate, the surface of the AG layer may form a rugged shape, such as a mountain and a pit similar to a photovoltaic peak, and the peak of the mountain is extremely sharp, so that when the surface of the 3A glass is pressed and rubbed by an external force, the stress area of the peak of the mountain is small, according to the pressure principle formula: the pressure P = pressure F/force-bearing area S indicates that the force-bearing area is small and the pressure to be borne is large, and therefore, the 3A glass has relatively poor wear resistance. Further, after the AG layer is formed on the glass substrate, the AG layer is polished, namely the peak tops of the peaks are ground, and after the AG layer is ground, the stress area of the 3A glass when the AG layer is pressed and rubbed by external force is increased, so that the pressure intensity of the 3A glass is reduced, and the wear resistance of the glass is improved.

More specifically, when the 3A glass manufactured by the method for manufacturing the 3A glass is rubbed under the conditions of 0000# steel wool, 20mm x 20mm large and small grinding heads, the stroke of 1.5inch, the speed of 60 cycles/min and the load weight of 1000g, the water drop angle can be larger than 100 degrees when the 3A glass is rubbed for about 2000 times, and the surface of the 3A glass has no friction marks. In the related art, when the 3A glass is rubbed about 800 times, the 3A glass surface has a rubbing trace. As described above, the 3A glass produced by the method for producing 3A glass of the present application has high abrasion resistance.

Further, in the polishing process of the 3A glass, as the polishing degree (i.e., the degree of surface particle reduction) is changed, the Rz value (the degree of surface particle reduction) of the 3A glass is gradually decreased, the Gloss value (Gloss) of the surface of the 3A glass is gradually increased, and the Haze value (Haze) is gradually decreased, and the relative change relationship is shown in the following table and fig. 4 and 5. Specifically, it should be noted that the haze is the percentage of the total transmitted light intensity of the transmitted light intensity deviating from the incident light by an angle of 2.5 ° or more, i.e., an important parameter for the optical transparency of the transparent or semitransparent material, and that a larger haze means a decrease in the gloss of the film and in the transparency, especially the degree of image formation. Gloss represents the degree to which the surface of an object is close to a mirror surface, with higher gloss indicating that the surface of the glass is closer to a mirror surface. The main purpose of the AG layer is anti-glare, and the main principle of anti-glare is diffuse reflection, and the main index for measuring diffuse reflection is glossiness.

Further, in order to ensure the parameter performance of the AG layer on the surface of the 3A glass, the polishing degree of the AG layer of the 3A glass is controlled accurately, the too deep polishing degree can damage the effect of the AG layer of the 3A glass and influence the anti-glare effect of the 3A glass, and the too light polishing degree can lead the wear resistance of the 3A glass not to be improved. Through tests, when the Rz value of the 3A glass is reduced by more than 0.01 μm, the friction resistance of the 3A glass is improved, but when the Rz value is reduced by 0.15 μm due to the polishing of the 3A glass, the parameters of the AG layer of the 3A glass are obviously changed, and the change range of the glossiness and the haze of the 3A glass is obviously increased, so that the performance of the 3A glass is influenced. Thus, in some embodiments, the AG layer is polished to a degree that surface particles of the AG layer are depleted to a range of 0.01 μm to 0.15 μm.

In some embodiments, the method of making 3A glass further comprises the steps of: after tempering the glass substrate and the AG layer, the AG layer is polished. Specifically, because the material hardness of the surface of the 3A glass is lower before tempering, when the surface of the 3A glass is polished, the particles of the AG layer on the surface of the 3A glass can be quickly ground flat, and the polished surface can have friction lines, so that the effect of the AG layer on the surface of the 3A glass is damaged, and the anti-glare effect of the 3A glass is finally influenced. Therefore, after the glass substrate and the AG layer are tempered, the AG layer is polished without affecting the anti-glare effect of the 3A glass.

In some embodiments, the manner of polishing is physical polishing. Specifically, the polishing can be performed by physical polishing, such as polishing with a polishing wheel, and in particular, the physical polishing is low in processing cost and beneficial to saving cost.

In some embodiments, the AG layer is formed by chemical etching or physical spraying. Specifically, the surface of the glass substrate can be changed into a matte surface by means of chemical etching or physical spraying, so that the glass substrate has an anti-glare function.

In some embodiments, the AR layer is made by way of a coating. Specifically, after the surface of the AG layer is specially treated, the AG layer is coated with different film layers, so that the 3A glass can have functions of increasing transmittance, reducing reflectance, and the like.

In some embodiments, the AF layer is made by spraying. Specifically, a layer of nano chemical material is coated on the surface of the AR layer, so that the AR layer has the functions of stronger hydrophobicity, oil resistance, fingerprint resistance and the like.

In some embodiments, the surface particles of the AG layer have a size of 30 μm to 200 μm. Specifically, the surface grains of the AG layer may be similar to the pixels, and the finer and more, the higher the definition, and thus, the higher the definition of the AG layer when the size of the surface grains of the AG layer is 30 μm to 200 μm.

In some embodiments, the thickness of the AF layer is 10nm to 30nm and the thickness of the AR layer is 150nm to 300nm. Specifically, the AF layer mainly plays a role in preventing fingerprints, the AR layer mainly plays a role in preventing reflection, in order to ensure that the effect of preventing fingerprints is just right, fingerprints cannot be prevented, waste caused by too much spraying cannot be caused, and therefore the thickness of the AF layer is 10nm-30nm. Similarly, in order to make the anti-reflection effect rigid, the AR layer is 150nm-300nm thick, and the AR layer cannot be anti-reflection and cannot be wasted due to too much spraying.

In some embodiments, the 3A glass is made by the method of making the 3A glass of any of the preceding embodiments. Specifically, when the 3A glass produced by the method of producing the 3A glass of the present application is rubbed under the conditions of 0000# steel wool, 20mm × 20mm large and small grinding heads, a stroke of 1.5inch, a speed of 60 cycles/min, and a load weight of 1000g, the water droplet angle may be greater than 100 degrees when the rubbing is performed for about 2000 times, and the surface of the 3A glass has no rubbing mark. As described above, the 3A glass produced by the method for producing 3A glass of the present application has high abrasion resistance.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
