[0032] In the description of the present invention, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0033] In order to achieve an anti-glare effect during production, the surface of 3A glass is specially treated so that the reflective surface of the 3A glass becomes a matte surface, thereby reducing light reflection and achieving the purpose of not being glaring.
[0034] In the process of matte treatment of the surface of 3A glass, the surface of 3A glass will be processed into an uneven plane, so that the abrasion resistance of the surface of 3A glass is poor. Therefore, in order to solve the above problem, the applicant of the present application proposes a method for manufacturing 3A glass.
[0035] For further information, please refer to Figure 1 In some embodiments, a method for making 3A glass comprises the steps of:
[0036] S100, forming an AG layer on a glass substrate;
[0037] S200, polishing the AG layer;
[0038] S300, forming an AR layer on the polished AG layer;
[0039] S400 , forming an AF layer on the AR layer.
[0040] Among them, the AG (Anti Glare) layer can have an anti-glare effect, the polishing can be done by chemical polishing and physical polishing, the AR (Anti Reflection) layer can have an anti-reflection effect, and the AF (Anti Fingerprint) layer can have an anti-fingerprint effect.
[0041] For details, please refer to Figure 2 and Figure 3 After the AG layer is formed on the glass substrate, the surface of the AG layer will form an uneven shape, such as undulating peaks and pits, and the peaks of the peaks are extremely sharp. In this way, when the surface of the 3A glass is pressed and rubbed by external force, the force area of the peaks is small. According to the pressure principle formula: Pressure P = Pressure F / Forced Area S, it can be known that the force area is small and the pressure is large. Therefore, the wear resistance of 3A glass is relatively poor. Further, after the AG layer is formed on the glass substrate, the AG layer is polished, that is, the "peak of the peak" is smoothed. After smoothing, the force area when it is pressed and rubbed by external force is increased. In this way, the pressure on the 3A glass is reduced, and therefore, its wear resistance is improved.
[0042] More specifically, when the 3A glass made by the manufacturing method of the 3A glass of the present application is rubbed under the conditions of 0000# steel wool, 20mm*20mm grinding head, stroke: 1.5inch, speed: 60cycle / min, load weight: 1000g, after rubbing for about 2000 times, the water drop angle can be greater than 100 degrees, and there are no friction marks on the surface of the 3A glass. However, in the related art, when the 3A glass is rubbed for about 800 times, there will be friction marks on the surface of the 3A glass. In this way, the 3A glass made by the manufacturing method of the 3A glass of the present application has high wear resistance.
[0043] Furthermore, during the polishing process of 3A glass, as the polishing degree (i.e., the degree to which surface particles are reduced) changes, the Rz value (the degree to which surface particles are reduced) of the 3A glass gradually decreases, the Gloss value of the surface of the 3A glass gradually increases, and the Haze value gradually decreases. For the relative change relationship, please refer to the following table and Figure 4 and Figure 5 . Specifically, it should be noted that haze is the percentage of transmitted light intensity that deviates from the incident light by more than 2.5° to the total transmitted light intensity, that is, it is an important parameter for the optical transparency of transparent or translucent materials. The greater the haze, the lower the gloss and transparency of the film, especially the imaging degree. Glossiness indicates the degree to which the surface of an object is close to a mirror. The higher the glossiness, the closer the glass surface is to a mirror. The main purpose of the AG layer is to prevent glare, and the main principle of producing anti-glare is diffuse reflection. The main indicator for measuring diffuse reflection is glossiness.
[0044] Haze reduction Gloss increase R 0.01 -0.4 3 0.02 -0.45 3.5 0.03 -0.55 4 0.04 -0.6 4.2 0.05 -0.65 4.5 0.06 -0.71 4.8 0.07 -0.75 5 0.08 -0.85 5.2 0.09 -0.95 5.5 0.10 -1.05 5.8 0.11 -1.15 6.1 0.12 -1.25 6.3 0.13 -1.35 7.2 0.14 -1.45 8.1 0.15 -1.65 9.3 0.16 -1.95 10.8 0.17 -2.05 14.5 0.18 -2.43 16.2 0.19 -2.67 18.3
[0045] Furthermore, 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 must be precisely controlled. Too deep a polishing degree will destroy the effect of the AG layer of the 3A glass and affect the anti-glare effect of the 3A glass. Too light a polishing degree will result in the wear resistance of the 3A glass not being improved. After testing, when the Rz value of the 3A glass decreases by more than 0.01μm, the friction resistance of the 3A glass will be improved. However, when the polishing of the 3A glass causes the Rz to drop by 0.15μm, the parameters of the AG layer of the 3A glass will change significantly, and the gloss and haze changes of the 3A glass will be significantly aggravated, thereby affecting the performance of the 3A glass. Therefore, in some embodiments, the AG layer is polished so that the surface particles of the AG layer are reduced to a degree of 0.01μm-0.15μm.
[0046] In some embodiments, the method for making 3A glass further includes the step of: polishing the AG layer after tempering the glass substrate and the AG layer. Specifically, since the material hardness of the 3A glass surface before tempering is relatively low, during polishing, the particles of the AG layer on the surface of the 3A glass will be quickly smoothed, and friction lines will appear on the polished surface, thereby destroying the effect of the AG layer on the surface of the 3A glass, and ultimately affecting the anti-glare effect of the 3A glass. Therefore, after tempering the glass substrate and the AG layer, polishing the AG layer will not affect the anti-glare effect of the 3A glass.
[0047] In some embodiments, the polishing method is physical polishing. Specifically, the polishing can be performed by physical polishing, such as polishing by a polishing wheel. More specifically, the physical polishing method has a lower processing cost, which is conducive to cost saving.
[0048] In some embodiments, the AG layer is made by chemical etching or physical spraying. Specifically, by chemical etching or physical spraying, the surface of the glass substrate can be turned into a matte surface, so that it has an anti-glare function.
[0049] In some embodiments, the AR layer is made by coating. Specifically, after the surface of the AG layer is specially treated, it is coated with different film layers, which can make the 3A glass have the functions of increasing transmittance and reducing reflectivity.
[0050] 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 to make it have strong hydrophobicity, oil resistance, anti-fingerprint and other functions.
[0051] In some embodiments, the size of the surface particles of the AG layer is 30 μm-200 μm. Specifically, the surface particles of the AG layer can be similar to pixels, the finer and more numerous, the higher the definition. Therefore, when the size of the surface particles of the AG layer is 30 μm-200 μm, the definition of the AG layer is high.
[0052] In some embodiments, the thickness of the AF layer is 10nm-30nm, and the thickness of the AR layer is 150nm-300nm. Specifically, the AF layer mainly plays an anti-fingerprint effect, and the AR layer mainly plays an anti-reflection effect. In order to make the anti-fingerprint effect just right, it will not fail to prevent fingerprints, nor will it cause waste due to too much spraying. Therefore, the thickness of the AF layer is 10nm-30nm. Similarly, in order to make the anti-reflection effect just right, it will not fail to prevent reflection, nor will it cause waste due to too much spraying. Therefore, the thickness of the AR layer is 150nm-300nm.
[0053] In some embodiments, 3A glass is made by the manufacturing method of 3A glass in any of the above embodiments. Specifically, when 3A glass made by the manufacturing method of 3A glass of the present application is rubbed under the conditions of 0000# steel wool, 20mm*20mm grinding head, stroke: 1.5inch, speed: 60cycle / min, load weight: 1000g, after rubbing for about 2000 times, the water drop angle can be greater than 100 degrees, and there is no friction mark on the surface of the 3A glass. In this way, the 3A glass made by the manufacturing method of 3A glass of the present application has high wear resistance.
[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
