Description

Technical Field

[0001] The present invention relates to the technical field of glass surface treatment, and specifically to a preparation method of anti-glare glass. Background Art

[0002] Anti-glare glass is a functional glass with a special surface structure. By constructing a micron-scale rough structure on the glass surface, incident light is diffusely reflected, effectively reducing specular reflection and glare interference, significantly improving the visibility and use comfort of display devices in strong light or outdoor environments, and is widely used in electronic displays, vehicle-mounted central control systems, industrial control interfaces, and smart home fields.

[0003] Currently, the preparation of anti-glare glass mainly relies on two technical routes: the spraying method and the chemical etching method. The spraying method forms a moderately rough diffuse reflection interface by covering a layer of anti-glare coating containing nanoparticles on the glass surface. This method has the advantages of simple operation, high preparation efficiency, and low cost, and is particularly suitable for large-scale industrial applications. However, due to the relatively weak adhesion of the sprayed coating and the low hardness of the material, its wear resistance is limited, and scratches or local peeling are likely to occur during use, affecting long-term stability. The chemical etching method directly constructs a microscopic rough structure on the surface of the glass substrate by immersing the glass in an acidic or alkaline solution for corrosion treatment. The anti-glare glass prepared in this way has excellent structural stability and wear resistance, and is suitable for scenarios with high requirements for durability. However, this method has a high technical threshold in adjusting the etching morphology and etching depth during the etching process, with a large processing complexity and a relatively low yield rate, and cannot flexibly design the gloss and haze of the glass, which limits its popularization and application. Summary of the Invention

[0004] Aiming at the above technical problems, the present invention provides a preparation method of anti-glare glass, which can prepare anti-glare glass with an adjustable gloss between 50 and 80 and an adjustable haze between 5 and 20%, and can design the gloss and haze of the glass according to actual needs. It is a preparation method of anti-glare glass with controllable structure, adjustable gloss and haze.

[0005] The present invention is specifically realized through the following technical solutions. A preparation method of anti-glare glass proposed according to the present invention includes the following steps: (1) After cleaning the glass substrate, put it into a plasma cleaner for cleaning to make the surface of the glass substrate hydrophilic; (2) Disperse polystyrene microsphere powder into a mixed solution of alcohol and deionized water, and perform ultrasonic oscillation with a cell disruptor to obtain a polystyrene microsphere emulsion; (3) Add deionized water into a glass container, dropwise coat the polystyrene microsphere emulsion prepared in step (2) onto the glass substrate treated in step (1), and then slowly immerse the glass substrate into the deionized water in the glass container. The polystyrene microsphere emulsion uniformly spreads on the deionized water surface, forming a large-area film floating on the deionized water surface; (4) After step (3) is completed, let it stand for 30 - 100 min, and then add a sodium dodecyl sulfate solution with a mass fraction of 2% dropwise into the aforementioned glass container; after the addition of sodium dodecyl sulfate, the surface tension of the liquid surface can be changed, and the liquid surface will suddenly spread around with the dropping point as the center, making the polystyrene microspheres arrange more closely on the liquid surface; (5) After step (4) is completed, after the liquid surface in the glass container stabilizes, slowly lift the glass substrate upward at a speed of 2 - 10 cm / min to transfer the polystyrene microsphere film onto the glass substrate; (6) After step (5) is completed, heat the glass substrate with the polystyrene microsphere film at 110 - 130 °C. By heating, the polystyrene microspheres slightly melt to make them more firmly bonded to the glass substrate; (7) After step (6) is completed, immerse the glass substrate in a glass etching solution. The glass etching solution selectively etches the glass substrate through the gaps between the polystyrene microspheres, and the glass covered by the polystyrene microspheres is not etched; (8) After step (7) is completed, clean the surface of the glass substrate with deionized water, and then ultrasonically clean it in a toluene solvent to remove the polystyrene microsphere film on the surface of the glass substrate, obtaining the anti-glare glass.

[0006] In the preparation method of the aforementioned anti-glare glass, in step (1), the cleaning time of the glass substrate in the plasma cleaner is 10 - 30 min.

[0007] In the preparation method of the aforementioned anti-glare glass, in step (2), the particle size of the polystyrene microsphere powder is 800 nm, the volume ratio of alcohol to deionized water in the mixed solution is 1:1, and the mass concentration of the polystyrene microspheres in the polystyrene microsphere emulsion is 1%.

[0008] In the preparation method of the aforementioned anti-glare glass, in step (2), the ultrasonic oscillation time is 20 - 60 s.

[0009] In the preparation method of the aforementioned anti-glare glass, in step (3), the dropwise coating amount of the polystyrene microsphere emulsion on the surface of the glass substrate is: for every 15 cm 2 2 mL of the polystyrene microsphere emulsion is dropwise coated on the surface of the glass substrate (unilateral area).

[0010] For the preparation method of the aforementioned anti-glare glass, in step (4), the addition amount of sodium dodecyl sulfate is: according to the size of the glass substrate, 0.15 mL of sodium dodecyl sulfate solution is dropped per square centimeter of the glass substrate (one-sided area).

[0011] For the preparation method of the aforementioned anti-glare glass, in step (6), the heating time is 10 - 30 min.

[0012] For the preparation method of the aforementioned anti-glare glass, in step (7), the main component of the glass etching solution is hydrofluoric acid. The mass concentration of hydrofluoric acid in the glass etching solution is 3 - 6%, and etching is carried out at room temperature with an immersion time of 0.5 - 2 min. Glass etching solutions with other components commercially available can also be used.

[0013] For the preparation method of the aforementioned anti-glare glass, in step (8), the ultrasonic cleaning time in toluene solvent is 10 - 20 min.

[0014] For the preparation method of the aforementioned anti-glare glass, the etched surface of the finally obtained anti-glare glass contains a plurality of regularly arranged circular glass surfaces and etched grooves interspersed between the circular glass surfaces. The diameter of the circular glass surface is about 0.8 μm.

[0015] For the preparation method of the aforementioned anti-glare glass, by adjusting the concentration of hydrofluoric acid and the etching time in the etching solution, anti-glare glasses with different gloss degrees and haze degrees are obtained. The gloss degree of the anti-glare glass at 60° is adjustable between 50 and 80, and the haze degree is adjustable between 5% and 20%.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. By means of the above technical solutions, the present invention can achieve quite high technical progressiveness and practicality, and has wide utilization value. It has at least the following advantages: In the present invention, a polystyrene microsphere emulsion is first drop-coated on the surface of a glass substrate. After being immersed in deionized water, the polystyrene microspheres are evenly dispersed on the surface of the deionized water to form a large-area film floating on the deionized water surface. By adding sodium dodecyl sulfate to the deionized water, the polystyrene microspheres are closely arranged on the liquid surface. Subsequently, the glass is slowly pulled upward at a constant speed so that the polystyrene microspheres on the liquid surface are transferred to the glass substrate. By heating, the polystyrene microspheres are slightly melted and firmly bonded to the surface of the glass substrate. There are gaps between the polystyrene microspheres. During the etching process, the etching solution selectively etches only into the gaps between the polystyrene microspheres, causing the gaps between the polystyrene microspheres to form etched grooves, and the glass covered by the polystyrene microspheres is not etched. After washing away the polystyrene microsphere mask, unetched circular glass surfaces and etched grooves sandwiched between the circular glass surfaces are left on the etched surface of the glass substrate. The circular glass surfaces are of uniform size and regular arrangement. Therefore, the etched grooves formed on the glass surface are also evenly distributed, ensuring the consistency of the mechanical properties and optical properties of each part of the anti-glare glass. By adjusting the concentration of hydrofluoric acid in the etching solution and the etching time, the etching depth can be adjusted, and thus anti-glare glass with different glossiness and haze can be obtained.

[0017] The preparation method of the present invention is simple and efficient, and the etching operation is controllable. It can prepare anti-glare glass with an adjustable glossiness between 50 and 80 and an adjustable haze between 5 and 20 at 60°. The glossiness and haze of the glass can be designed according to actual needs. It is a preparation method of anti-glare glass with controllable structure, adjustable glossiness and haze.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention will be described in detail below with specific embodiments. For those not specified in the following embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. The raw materials and reagents used, if not specified for the manufacturer, are all conventional products that can be obtained through commercial purchase. In the embodiments, the cleaning of the glass substrate can be carried out with alcohol having a mass fraction of 98%, but the present invention is not limited thereto. The glass etching solution used in the following embodiments is a hydrofluoric acid solution having a mass fraction of 3% to 6%, but the present invention is not limited thereto, and other commercially available glass etching solutions with other components can also be used. Example 1

[0023] (1) After cleaning the glass substrate 1, put it into a plasma cleaner and clean it for 20 min to make the surface of the glass substrate hydrophilic; (2) Disperse polystyrene microsphere powder with a particle size of 800 nm into a mixed solution of alcohol and deionized water (v:v = 1:1), and perform ultrasonic oscillation for 40 s with a cell disruptor to form a polystyrene microsphere emulsion. The concentration of polystyrene microspheres in the polystyrene microsphere emulsion is 1 wt%; (3) Add deionized water to a glass container, and drop the polystyrene microsphere emulsion prepared in step (2) onto the glass substrate treated in step (1). The dropping amount is 2 mL of polystyrene microsphere emulsion per 15 cm 2 of the glass substrate surface (one-sided area); then slowly immerse the glass substrate into the deionized water in the aforementioned glass container. The polystyrene microsphere emulsion spreads evenly on the deionized water surface to form a large-area film floating on the deionized water surface; (4) After step (3) is completed, let it stand for 60 min, and then drop a sodium dodecyl sulfate solution with a mass fraction of 2% into the aforementioned glass container. According to the area of the glass substrate surface (one-sided area), 0.15 mL of sodium dodecyl sulfate solution is dropped per square centimeter of the glass substrate; after the addition of sodium dodecyl sulfate, the surface tension of the liquid surface can be changed, and the liquid surface suddenly spreads around with the dropping point of sodium dodecyl sulfate as the center, making the polystyrene microspheres arrange more closely on the liquid surface; In this step, sodium dodecyl sulfate can be dropped from one side of the liquid surface of the glass container. After dropping, the surface tension of the liquid surface changes and squeezes the polystyrene microspheres to the other side, making the polystyrene microspheres arrange more closely (the same below); (5) After step (4) is completed, after the liquid surface in the glass container is stable (about 10 - 20 min), slowly lift the glass substrate upward at a speed of 4 cm / min to transfer the polystyrene microsphere film onto the glass substrate; (6) After step (5) is completed, heat the glass substrate with the polystyrene microsphere film at 120 °C for 20 min to make the polystyrene microspheres slightly melt and bind more firmly to the glass substrate; After step (6), the glass substrate is immersed in a glass etching solution. The mass concentration of hydrofluoric acid in the glass etching solution is 4%, and the immersion time is 1 min. The glass etching solution selectively etches the glass substrate through the gaps between the polystyrene microspheres. After etching, etching grooves 2 are formed in the gaps between the polystyrene microspheres, and the glass covered by the polystyrene microspheres is not etched. After step (7), the hydrofluoric acid on the surface of the glass substrate is washed clean with deionized water, and then ultrasonically cleaned in toluene solvent for 15 min to remove the polystyrene microsphere film on the surface of the glass substrate, obtaining the anti-glare glass.

[0024] The performance indexes of the anti-glare glass are detected. Its glossiness is detected with a glossmeter, and its haze is detected with a haze meter. After detection, the glossiness of the anti-glare glass prepared in this example at 60° is 61, and the haze is 13.9%.

[0025] Figure 1 is a schematic cross-sectional view of the anti-glare glass prepared by the present invention, including a glass substrate 1. Etching grooves 2 are formed on the glass substrate 1, and the depth of the etching grooves 2 can be controlled by regulating the concentration of hydrofluoric acid in the etching solution and the etching time.

[0026] Figure 2 is an SEM image of the etched surface of the anti-glare glass prepared in this example at 5000 times magnification. It can be clearly seen that the etched surface of the glass contains multiple regularly arranged circular glass surfaces. The circular glass surfaces were originally covered by polystyrene microspheres. During the etching process of the glass etching solution, the gaps between the polystyrene microspheres were etched to form etching grooves, and the glass surfaces covered by the polystyrene microspheres were not etched. After subsequent toluene cleaning to remove the polystyrene microsphere mask, one by one circular glass surfaces (not etched) with uniform size and regular arrangement and etching grooves sandwiched between the circular glass surfaces are left on the etched surface of the glass. The etching grooves are recessed into the glass interior relative to the circular glass surfaces, thereby forming a microscopic rough structure on the glass surface and making the glass have an anti-glare effect. In addition, Figure 2 it can also be seen that the diameter of the circular glass surface is about 0.8 μm, which is equivalent to the particle size of the polystyrene microspheres. Example 2

The concentration of polystyrene microspheres in the polystyrene microsphere emulsion is 1 wt%. (3) Add deionized water into a glass container, and dropwise coat the polystyrene microsphere emulsion prepared in step (2) onto the glass substrate treated in step (1). The dropping amount is 2 mL of the polystyrene microsphere emulsion per 15 cm 2 of the surface area of the glass substrate (one-sided area); then slowly immerse the glass substrate into the deionized water in the aforementioned glass container. The polystyrene microsphere emulsion evenly spreads on the deionized water surface, forming a large-area thin film floating on the deionized water surface; (4) After step (3) is completed, let it stand for 100 min, and then add a sodium dodecyl sulfate solution with a mass fraction of 2% dropwise into the aforementioned glass container. According to the surface area of the glass substrate (one-sided area), add 0.15 mL of the sodium dodecyl sulfate solution per square centimeter of the glass substrate; after the addition of sodium dodecyl sulfate, the surface tension of the liquid surface can be changed, and the liquid surface will suddenly spread around with the dropping point as the center, making the polystyrene microspheres arrange more closely on the liquid surface; (5) After step (4) is completed, after the liquid surface in the glass container stabilizes (about 10 - 20 min), slowly lift the glass substrate upward at a speed of 10 cm / min to transfer the polystyrene microsphere thin film onto the glass substrate; (6) After step (5) is completed, heat the glass substrate with the polystyrene microsphere thin film at 130 °C for 10 min to slightly melt the polystyrene microspheres through heating so that they are more firmly bonded to the glass substrate; (7) After step (6) is completed, immerse the glass substrate in a glass etching solution. The mass concentration of hydrofluoric acid in the glass etching solution is 3%, and the immersion time is 0.5 min; the glass etching solution selectively etches the glass substrate through the gaps between the polystyrene microspheres. After etching, etching grooves 2 are formed in the gaps between the polystyrene microspheres, and the glass covered by the polystyrene microspheres is not etched; (8) After step (7) is completed, clean the hydrofluoric acid on the surface of the glass substrate with deionized water, and then ultrasonically clean it in toluene solvent for 10 min to remove the polystyrene microsphere thin film on the surface of the glass substrate, obtaining the anti-glare glass.
