Referring to fig. 2 and fig. 3, in an embodiment of the invention, a glass product is provided, which includes a glass substrate 100 and an anti-glare structure formed on a surface of the glass substrate 100. The anti-glare structure comprises a first texture microstructure 200 formed on the surface of the glass substrate 100, and a second texture microstructure 300 formed on the surface of the first texture microstructure 200. The first textured microstructure 200 includes a first protrusion 210 and a first recess 220. The second textured microstructure 300 includes a second protrusion 310 and a second recess 320. The span of the second protrusion 310 is less than the span of the first protrusion 210, and the span of the second recess 320 is less than the span of the first recess 220.
The span of the second protrusion 310 herein means a horizontal distance between both ends of the second protrusion 310. The span of the first protrusion 210 refers to the horizontal distance between the two ends of the first protrusion 210. The span of the second recess 320 refers to the horizontal distance between the two ends of the second recess 320. The span of the first recess 220 refers to the horizontal distance between the two ends of the first recess 220.
The first texture microstructure 200 in this embodiment is the same as or similar to a common anti-glare structure, the surfaces of the first protrusions 210 and the first recesses 220 are both smooth spherical surfaces, the shapes of the second protrusions 310 and the second recesses 320 can be respectively similar to the shapes of the first recesses 220 and the first protrusions 210, or protrusions and recesses with concave-convex structures on the surfaces can be used, which is not limited herein, as long as the size of the protrusions is smaller than that of the first protrusions 210 and the first recesses 220. Dimensions as used herein include height, depth and span.
Specifically, the first texture microstructure 200 may be manufactured by one-time frosting process, and the second texture microstructure 300 may be manufactured by at least one-time frosting process after the first texture microstructure 200 is formed. The first concave portion 220 is a concave portion formed on the surface of the glass article after the first frosting process, and the first convex portion 210 is a convex portion protruding from the surface of the second concave portion 220 without being etched or with a low degree of etching. The second concave portion 320 is a concave portion formed on the surfaces of the first convex portion 210 and the first concave portion 220 after the glass product is subjected to the second frosting treatment or the multiple frosting treatments after the first frosting treatment, and the second convex portion 310 is a convex portion protruding from the surface of the second concave portion 320, which is not etched or is etched to a low degree, on the surfaces of the first convex portion 210 and the first concave portion 220.
Of course, the first texture microstructure 200 and the second texture microstructure 300 can also be made by other methods similar to the above-mentioned manufacturing principle, such as multiple acid etching or frosting, acid etching and the like; the first texture microstructure 200 and the second texture microstructure 300 may be a relatively regular wave-shaped structure as shown in fig. 1 and 2, or an irregular hill-shaped structure, which is not limited to the above, as long as the second protrusions 310 and the second recesses 320 having smaller sizes than the first protrusions 210 and the first recesses 220 in the first texture microstructure 200 can be formed on the surface of the first protrusions 210 and the first recesses 220.
Wherein the span of the second protrusion 310 is less than the span of the first protrusion 210, and the span of the second recess 320 is less than the span of the first recess 220. In this way, the concave-convex structure having both the second convex portion 310 and the second concave portion 320 may be formed on either side of the curved line of the first convex portion 210 and the second concave portion 320, so that the light can be diffusely reflected at a plurality of angles after being irradiated thereon.
The glass product provided by the application has a novel anti-glare structure formed on the surface, and the anti-glare structure comprises a first texture microstructure 200 and a second texture microstructure 300 formed on the surface of the first texture microstructure 200, so that the surfaces of the convex parts and the concave parts in the anti-glare structure are not smooth curved surfaces any more, but are full of second convex parts 310 and second concave parts 320, and further the surfaces of the convex parts and the concave parts in the anti-glare structure become uneven fog surfaces. In this way, light may form multiple diffuse reflections therein. Therefore, the light reflected by the anti-glare structure in the glass product provided by the application is softer, and the anti-glare effect is better.
In one specific embodiment, the first textured microstructure 200 is formed by one sanding process and the second textured microstructure 300 is formed by at least one sanding process. When the second texture microstructure 300 is manufactured through one-time frosting process, the surfaces of the second protrusions 310 and the second recesses 320 are smooth curved surfaces; when the second texture microstructure 300 is manufactured through the multiple frosting process, the surfaces of the second protrusions 310 and the second recesses 320 become a matte surface having many concave-convex structures. The number of frosting processes required for the preparation of the second texture microstructure 300 may be set according to the roughness, diffuse reflection effect, etc. of the surface of the final glass product that it wants to obtain. Therefore, glass products with different roughness and different anti-glare effects can be prepared by a manufacturer according to the design or use requirements of products, and the requirements of cover plates of different electronic equipment are met.
To improve the glare resistance of the glass article, in an alternative embodiment, the span of the second protrusion is less than or equal to 1/2 of the span of the first protrusion, and the span of the second recess is less than or equal to 1/2 of the span of the first recess. In this way, the surfaces of the first concave part 220 and the first convex part 210 can be distributed with a plurality of second concave parts 320 and second convex parts 310, so that the surfaces thereof become fog surfaces, thereby improving the effect of diffuse reflection of light and the anti-glare effect.
To avoid the addition of the second texture microstructure 300, which may have a greater effect on the overall roughness of the anti-glare structure, in an alternative embodiment, the height of the second protrusions 310 is less than the height of the first protrusions 210; and/or the depth of the second recess 320 is less than the depth of the first recess 220.
The height of the second protrusion 310 is a vertical distance from the top of the second protrusion 310 to the surface of the second recess 320. The height of the first protrusion 210 refers to a vertical distance of the tip of the first protrusion 210 from the surface of the first recess 220. The depth of the second recess 320 refers to the perpendicular distance between the lowest point of the second recess 320 and its top or some reference surface. The depth of the first recess 220 refers to the perpendicular distance between the lowest point of the first recess 220 and its top or some reference surface. The reference surface may be a surface before etching or may be another plane artificially defined by an experimenter.
Further, the height of second protrusion 310 is less than or equal to 1/2 of the height of first protrusion 210; and/or; the depth of the second recess 320 is less than or equal to 1/2 of the depth of the first recess 220.
Fig. 3 shows a specific embodiment in which the height of the second protrusion 310 is equal to the depth of the second recess 320, both H1; the height of the first protrusion 210 is equal to the depth of the first recess 220, and is H. Wherein H/H1 is more than or equal to 2, and H1 is more than or equal to 0.05um and less than or equal to 10 um. The span of the second convex portion 310 is equal to the span of the second concave portion 320, both W1; the span of the first convex portion 210 is equal to the span of the first concave portion 220, and is W. Wherein W/W1 is more than or equal to 2; w is more than or equal to 0.05um and less than or equal to 25 um. At this time, the surfaces of the first concave part 220 and the first convex part 210 are uniformly distributed with the second concave part 320 and the second convex part 310, so that the surfaces of the first concave part 220 and the first convex part 210 are not curved surfaces of the light source but become uneven. The anti-glare structure is tested to have better effect on light diffuse reflection and anti-glare effect than the anti-glare structure shown in fig. 1.
In another embodiment of the present invention, an electronic device cover is provided. The surface of the electronic equipment cover plate is formed with an anti-glare structure. The anti-glare structure has the same structural features as the anti-glare structures in the embodiments, and the functions of the anti-glare structure are the same, which are not described herein again.
In another embodiment of the present invention, an electronic device is provided. The electronic equipment provided by the embodiment of the invention comprises the electronic equipment cover plate provided by the embodiment. The electronic device cover plate has the same structural features as the electronic device cover plate in the above embodiments, and functions of the electronic device cover plate are the same, which are not described herein again.
Referring to fig. 5, in another embodiment of the present invention, a method for manufacturing a glass product is provided, which includes the following steps:
step S1: and (4) surface pretreatment.

and (5) washing the substrate.
Specifically, an ultrasonic cleaner may be used for the rinsing to ensure the cleanness of the surface of the glass substrate 100. The hydrofluoric acid solution is adopted to pretreat the surface to be etched of the glass substrate 100, so that not only can impurities on the surface to be etched of the glass substrate 100 be removed, but also a micro texture structure can be formed on the surface to be etched of the glass substrate 100, so that the frosting solution is uniformly distributed on the surface to be etched of the glass substrate 100 in the subsequent frosting treatment operation, and the smooth operation of the frosting treatment operation is further ensured.
The polishing treatment step comprises the following steps:
and (3) carrying out spray polishing by using a hydrofluoric acid solution with the concentration of 5-10%, wherein the spray time is 3-5 min.
