Description

Technical Field

[0001] The present invention belongs to the technical field of glass surface treatment, and particularly relates to a super wear-resistant and hydrophobic AG glass and a preparation method thereof. Background Art

[0002] AG glass (Anti-Glare Glass), that is, anti-glare glass, is a functional glass whose surface is treated by a special process to reduce light reflection and glare interference. Compared with ordinary glass, AG glass has less specular reflection. In a strong light environment, it can reduce the amount of specular reflected light entering the human eye, thereby achieving the purpose of anti-glare, improving the visual effect, and reducing the visual fatigue of users.

[0003] Currently, AG glass is mainly treated by spraying method and chemical etching method on the glass surface. The spraying method is a relatively widely used method for preparing AG glass in current industrial production. It usually sprays a layer of nano-coating with anti-glare function on the glass surface to form a diffuse reflection layer with a certain roughness on the glass surface. The biggest advantage of this method is that the process is simple, the cost is low, and the production efficiency is high, which is suitable for large-scale production, especially for product lines in the consumer electronics field with high requirements for cost control and production capacity. However, since the coating is usually made of organic or inorganic mixed materials, its adhesion and hardness are relatively low, so the wear resistance is limited. The chemical etching method is a method of directly forming a rough structure on the glass body by chemically reacting and corroding the glass surface. The chemical etching process has high requirements for process control, especially the control of etching depth is difficult. Chemical etching has an adverse effect on the optical performance, and also significantly weakens the mechanical strength of the glass body, reducing its impact resistance and bending resistance, thus limiting its application in some scenarios with high strength requirements.

[0004] With the continuous upgrading of display technology and user requirements, a single anti-glare function has been difficult to meet the usage requirements of high-end electronic devices. In order to further improve the practicality and user experience of AG glass, researchers and the industry have combined AG glass with a hydrophobic coating to develop a composite glass with both anti-glare and anti-fouling and self-cleaning functions. The hydrophobic coating can form a low surface energy structure on the glass surface, significantly reducing the adhesion of water droplets and stains on the surface, enabling the glass to have the "lotus effect", and having good waterproof, oil-proof and easy-to-clean characteristics, which is particularly important in outdoor or highly polluted environments. However, the common hydrophobic coatings on the market currently mostly use silicone-based or fluorine-based materials. Although these materials have excellent hydrophobic properties, their hardness is relatively low. Especially in scenarios of frequent contact or friction, they are extremely prone to wear, resulting in functional degradation.

[0005] In the process of combining a hydrophobic coating with AG glass, there are still many challenges. Under the synergistic effect of the double-layer functional coating, performance indicators such as the durability, transparency, and optical consistency of the overall structure also need to be balanced and optimized. How to improve the wear resistance and adhesion of the hydrophobic coating while ensuring the anti-glare effect is one of the important research directions in the current composite functionalization of AG glass. Summary of the Invention

[0006] The present invention provides a super wear-resistant hydrophobic AG glass and a preparation method thereof, aiming to improve the wear resistance and adhesion of its hydrophobic layer while ensuring the anti-glare effect and anti-fouling self-cleaning effect of the glass.

[0007] Specifically, the present invention is realized through the following technical solutions. A preparation method of a super wear-resistant hydrophobic AG glass according to the present invention includes the following steps: (1) After cleaning the glass substrate, a layer of silicon-acrylic emulsion layer is prepared on the glass surface by the roll coating method. After drying at room temperature, the silicon-acrylic emulsion layer cracks to form multiple cracks, obtaining a reticular silicon-acrylic cracking template; (2) Select an Al2O3 target with a purity of 99.99%, and use magnetron sputtering coating technology to prepare an Al2O3 film on the surface of the reticular silicon-acrylic cracking template obtained in step (1). The deposition temperature is room temperature, the deposition gas is an argon-oxygen mixed gas, the sputtering pressure is 0.8 - 1.2 Pa, and the sputtering power is 100 - 200 W; (3) After step (2) is completed, the obtained glass sample is put into acetone for ultrasonic cleaning. During the ultrasonic cleaning process, the Al2O3 deposited in the cracks of the silicon-acrylic cracking template remains, and the silicon-acrylic cracking template is removed. The remaining Al2O3 protrudes on the glass surface to form a crack-like Al2O3 grid. The grid structure of the Al2O3 grid is complementary to the grid structure of the silicon-acrylic cracking template. Subsequently, the glass sample with the Al2O3 grid is annealed at 400°C - 500°C to improve the hardness of the Al2O3 grid and the bonding force between the Al2O3 grid and the glass substrate; (4) The glass sample annealed in step (3) is immersed in a hydrophobic coating, taken out and baked to obtain a super wear-resistant hydrophobic AG glass.

[0008] In the preparation method of the aforementioned super wear-resistant hydrophobic AG glass, in step (1), the silicon-acrylic emulsion is poured on the glass substrate, and a Meyer rod is used to roll coat from one end of the glass to the other end to prepare a silicon-acrylic emulsion layer with a thickness of 10 - 20 μm on the glass surface. After drying at room temperature, the crack width of the obtained reticular silicon-acrylic cracking template is 2 - 3 μm, and the crack spacing is 15 - 25 μm.

[0009] In the preparation method of the aforementioned ultra-wear-resistant hydrophobic AG glass, in step (2), the flow rate ratio of argon to oxygen in the argon-oxygen mixed gas is 30:1; after coating, the thickness of the Al2O3 film is 300-1000 μm, and the thickness of the Al2O3 film is controlled by the deposition time.

[0010] In the preparation method of the aforementioned ultra-wear-resistant hydrophobic AG glass, in step (3), the ultrasonic cleaning time of the sample in acetone is 10-15 min, the annealing treatment time is 10-30 min, the wire width of the Al2O3 grid is 2-3 μm, and the wire spacing is 15-25 μm.

[0011] In the preparation method of the aforementioned ultra-wear-resistant hydrophobic AG glass, in step (4), the hydrophobic coating is a fluorosilane polymer hydrophobic coating, purchased from Naroco New Materials Technology Co., Ltd., and the model is NC319. The immersion is at room temperature, and the immersion time is 5-20 min. The hydrophobic coating fills between the wires of the Al2O3 grid and on the entire Al2O3 grid to form a hydrophobic layer. After taking it out, it is baked at 80 °C for 30-60 min to obtain the ultra-wear-resistant hydrophobic AG glass.

[0012] The present invention also provides an ultra-wear-resistant hydrophobic AG glass obtained according to the above preparation method, on which a crack-shaped Al2O3 grid is plated on the glass substrate. The wire width of the Al2O3 grid is 2-3 μm, the wire spacing is 15-25 μm, and a hydrophobic coating is filled between the wires of the Al2O3 grid and on the entire Al2O3 grid. The hydrophobic coating is a fluorosilane polymer.

[0013] Furthermore, the visible light transmittance of the aforementioned ultra-wear-resistant hydrophobic AG glass is ≥91%, the gloss at 60° is 80-100, the haze is 8-12%, the hydrophobic angle >150°, and after 10,000 times of steel wool friction, the hydrophobic angle >135°.

[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. By means of the above technical solution, 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, first, a layer of silicon-acrylic emulsion layer is prepared on the surface of a glass substrate by a roll coating method. After drying, the silicon-acrylic emulsion layer cracks to form multiple irregular cracks, obtaining a reticular silicon-acrylic cracking template with cracks. Subsequently, an Al2O3 film is deposited on the surface of the silicon-acrylic cracking template by a magnetron sputtering coating technique. The Al2O3 is deposited on the reticular silicon-acrylic cracking template and deposited in the cracks of the silicon-acrylic cracking template. Subsequently, through ultrasonic cleaning with acetone, the silicon-acrylic cracking template is removed, while the Al2O3 deposited in the cracks of the silicon-acrylic cracking template remains and protrudes on the surface of the glass substrate, forming a crack-like Al2O3 grid. Then, the glass sample is subjected to a high-temperature annealing treatment to improve the hardness of the Al2O3 grid and the bonding force between the Al2O3 grid and the glass substrate. The glass product is immersed in a hydrophobic coating, and the hydrophobic coating fills between the wires of the Al2O3 grid and on the entire Al2O3 grid, forming a hydrophobic layer. The Al2O3 grid deposited on the glass substrate effectively protects and locks the hydrophobic layer, and the hydrophobic layer is not easily worn during friction, thereby increasing the wear resistance of the hydrophobic layer. The Al2O3 grid deposited on the surface of the glass substrate scatters incident light, making the glass have an anti-glare effect.

[0015] The preparation method of the present invention is simple and efficient. By depositing a crack-like Al2O3 grid on the glass substrate to lock the hydrophobic material, the wear resistance of the hydrophobic layer of the glass is improved. The obtained super wear-resistant hydrophobic AG glass has both an anti-glare effect and a high light transmittance, and has an anti-fouling and self-cleaning function. The hydrophobic layer is locked by the Al2O3 grid and is not easily worn, having excellent wear resistance. Brief Description of the Drawings

[0025] Use a friction resistance tester to test the wear resistance of the super wear-resistant hydrophobic AG glass prepared in this example. The friction material is steel wool. After rubbing with steel wool (500 g pressure) for 10,000 times, the hydrophobic angle of the glass is 141°.
