Description

Technical Field

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

[0002] Anti-Glare (AG) glass, also known as anti-reflection glass, is a type of glass whose surface is specially treated to adjust the mirror reflection of the glass surface to diffuse reflection. Compared with ordinary glass, AG glass can reduce the interference of ambient light, improve the viewing angle and brightness of the display screen, reduce screen reflection, make the image clearer, the color more vivid and saturated, and at the same time eliminate eye fatigue caused by glare, and is widely used in display devices such as mobile phones, tablets or TVs.

[0003] AG glass can be produced by a spraying process. The spraying process sprays a coating containing silicon dioxide particles onto the glass surface through a spraying device, and attaches a coating layer on the glass surface to achieve the anti-glare effect. The spraying process has the advantages of convenience, high production efficiency, and the ability to process products with different gloss and haze. However, the hardness of AG glass produced by the spraying process is relatively low, resulting in poor scratch resistance of AG glass. Summary of the Invention

[0004] In view of this, the present invention provides an anti-glare coating, a preparation method of anti-glare glass, and anti-glare glass to solve the problem of poor scratch resistance of AG glass.

[0005] In a first aspect, the present invention provides an anti-glare coating. The components of the anti-glare coating include silicon dioxide particles, nano-ceramic polymer materials, alkyd resins, diluents, fluorides, and polytetrafluoroethylene. Among them, the mass percentage content of the silicon dioxide is 10%-20%, the mass percentage content of the alkyd resin is 15%-25%, the mass percentage content of the nano-ceramic polymer material is 30%-40%, the mass percentage content of the diluent is 10%-20%, the mass percentage content of the fluoride is 2%-5%, and the mass percentage content of the polytetrafluoroethylene is 3%-8%.

[0006] The anti-glare coating provided by the present invention, by adding nano-ceramic polymer materials to the anti-glare coating, after spraying onto the glass surface and then through high-temperature sintering and solvent volatilization, silicon dioxide, nano-ceramic polymer materials, and a small amount of fillers can be left on the glass surface, and the molecular structure is dense, so as to achieve the effects of high wear resistance and high hardness on the glass surface.

[0007] In an alternative embodiment, the mass percentage content of the silica is 10%-15%, the mass percentage content of the alkyd resin is 15%-25%, the mass percentage content of the nano-ceramic polymer material is 35%-40%, the mass percentage content of the diluent is 10%-20%, the mass percentage content of the fluoride is 2%-5%, and the mass percentage content of the polytetrafluoroethylene is 3%-8%.

[0008] In this embodiment, by limiting the mass percentage content of the nano-ceramic polymer material to 30%-40%, while improving the scratch resistance of the glass surface, the bonding strength between the anti-glare coating and the glass surface can be ensured.

[0009] In an alternative embodiment, the particle size of the nano-ceramic polymer material is 50nm-100nm.

[0010] In this embodiment, by limiting the particle size of the nano-ceramic polymer material to 50nm-100nm, the nano-ceramic polymer material can be evenly dispersed in the solvent, avoiding agglomeration or deposition of the nano-ceramic polymer material.

[0011] In a second aspect, the present invention provides a method for preparing an anti-glare glass, the method comprising: spraying a coating on the surface of a glass substrate to form an anti-glare coating, wherein the coating is the anti-glare coating of the first aspect or any one of its embodiments; and performing tempering treatment on the glass substrate sprayed with the anti-glare coating to obtain the anti-glare glass.

[0012] According to the method for preparing an anti-glare glass provided in this embodiment, first, the anti-glare coating is sprayed on the surface of the glass substrate to form an anti-glare coating, and then the glass substrate sprayed with the anti-glare coating is subjected to tempering treatment to obtain the anti-glare glass. In the present invention, spraying is performed first and then tempering. The temperature during the tempering treatment can make the glass substrate and the anti-glare coating in a softened state, thereby improving the adhesion and making it easier and more firm to bond the anti-glare coating and the glass substrate together.

[0013] In an alternative embodiment, the spraying the coating on the surface of the glass substrate to form an anti-glare coating includes: spraying the coating on the surface of the glass substrate through a spraying device to form the anti-glare coating, wherein the pressure of the nozzle of the spraying device is 4Mpa-8Mpa, the flow rate of the nozzle is 900g / min-1500g / min, and the mesh belt transmission speed of the spraying device is 300mm / min-600mm / min.

[0014] Through the above settings, the anti-glare coating containing silica particles and nano-ceramic polymer materials can be dispersed into uniform and fine droplets and evenly coated on the surface of the glass substrate.

[0015] In an alternative embodiment, the tempering treatment of the glass substrate sprayed with the anti-glare coating includes: tempering the glass substrate sprayed with the anti-glare coating through a tempering furnace to obtain the anti-glare glass, wherein the tempering temperature is 600°C - 700°C and the tempering duration is 5 min - 10 min. A tempering temperature of 600°C - 700°C can keep the glass substrate and the anti-glare coating in a softened state, enabling the glass substrate and the anti-glare coating to be better combined together.

[0016] In an alternative embodiment, before spraying the coating on the surface of the glass substrate, the method further includes: cleaning the glass substrate, and the cleaning treatment includes at least one of a cleaning treatment, a plasma treatment, or a corona treatment.

[0017] In this embodiment, cleaning the glass substrate before spraying can change the surface tension of the glass, making it easier for the anti-glare coating and the glass substrate to combine.

[0018] In an alternative embodiment, after obtaining the anti-glare glass, the method further includes: cleaning treatment, printing treatment, and baking treatment of the anti-glare glass. Through the above settings, the aesthetics of the anti-glare glass can be improved.

[0019] In an alternative embodiment, after the cleaning treatment, printing treatment, and baking treatment of the anti-glare glass, the method further includes: inspecting whether the anti-glare glass is qualified. By inspecting whether the anti-glare glass is qualified, it is possible to prevent defective anti-glare glass from leaving the factory and affecting the product qualification rate.

[0020] In a third aspect, the present invention provides an anti-glare glass, which is prepared by the method of the second aspect or any corresponding embodiment thereof.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, 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.

[0028] AG glass has a lower reflectance ratio through the principle of diffuse reflection. Using AG glass to make a display screen can reduce screen reflection, improve the clarity of the display image, and enable users to have a better visual effect.

[0029] Currently, there are mainly three processing techniques for AG glass, namely spraying, coating and chemical etching. The spraying process is to use a spraying device (spray gun or butterfly atomizer), with the aid of pressure or centrifugal force, to disperse the coating with silicon dioxide particles into uniform and fine droplets and coat them on the glass surface, and attach a coating layer on the glass surface to achieve the anti-glare effect. The coating process is a kind of atomized coating technology, adding a specially treated film on the glass surface, and performing fine concavo-convex processing on the surface of the film to prevent light from directly entering the eyes, thereby effectively reducing glare and reflection. Chemical etching is to make the original reflective surface of the glass become a matte diffuse reflection surface through special chemical process treatment, which can make the reflection effect blurred and prevent glare. For example, the flat glass is surface-etched with hydrofluoric acid to make the glass surface change from the original smooth and flat state to uneven, so as to form diffuse reflection of light and thus achieve the anti-glare function.

[0030] The spraying process has the advantages of being convenient and fast, high production efficiency, and being able to process products with different gloss degrees and haze degrees. It is a relatively excellent implementation method for AG glass processing. However, since the residue of the coating used in the spraying process after drying is basically silicon dioxide, the Mohs hardness of the glass surface is 5-5.5, resulting in poor surface scratch resistance.

[0031] In view of this, the present invention provides an anti-glare coating. By adding a nano-ceramic polymer material to the anti-glare coating, the surface hardness of the anti-glare glass can be improved, and thus the surface of the anti-glare glass can achieve the effects of high wear resistance and high hardness.

[0032] The anti-glare coating provided by the present invention will be described in detail below.

[0033] The components of the anti-glare coating provided by the present invention include silicon dioxide particles, nano-ceramic polymer materials, alkyd resins, diluents, fluorides, and polytetrafluoroethylene. Among them, the mass percentage content of silicon dioxide is 10%-20%, the mass percentage content of alkyd resin is 15%-25%, the mass percentage content of nano-ceramic polymer material is 30%-40%, the mass percentage content of diluent is 10%-20%, the mass percentage content of fluoride is 2%-5%, and the mass percentage content of polytetrafluoroethylene is 3%-8%.

[0034] Exemplarily, the mass percentage content of silicon dioxide is any value within 10%-20%. For example, the mass percentage content of silicon dioxide is 10%, 12%, 15%, 18%, or 20%, etc. The mass percentage content of alkyd resin is any value within 15%-25%. For example, the mass percentage content of alkyd resin is 15%, 18%, 20%, or 25%, etc. The mass percentage content of nano-ceramic polymer material is any value within 30%-40%. For example, the mass percentage content of nano-ceramic polymer material is 30%, 32%, 35%, 38%, or 40%, etc. The mass percentage content of diluent is any value within 10%-20%. For example, the mass percentage content of diluent is 10%, 15%, or 20%. The mass percentage content of fluoride is any value within 2%-5%. For example, the mass percentage content of fluoride is 2%, 3%, 4%, or 5%. The mass percentage content of polytetrafluoroethylene is any value within 3%-8%. For example, the mass percentage content of polytetrafluoroethylene is 3%, 5%, 7%, or 8%, etc.

[0035] It should be understood that the mass percentage contents of the silicon dioxide particles, nano-ceramic polymer materials, alkyd resins, diluents, fluorides, and polytetrafluoroethylene can vary according to requirements within the above-defined ranges. The present invention does not make any limitations as long as the sum of the mass percentage contents of the silicon dioxide particles, nano-ceramic polymer materials, alkyd resins, diluents, fluorides, and polytetrafluoroethylene is 100%.

[0036] Among them, the nano-ceramic polymer material has high wear resistance and hardness, with a Mohs hardness of up to 6.5. The alkyd resin acts as an adhesive, and the diluent can reduce the viscosity of the anti-glare coating, which is beneficial to spraying processing. Fluoride and polytetrafluoroethylene play a dispersing role, preventing the silicon dioxide particles from aggregating and causing blockage of the spraying equipment, which affects the spraying effect.

[0037] Specifically, the ability of a material to locally resist the penetration of a hard object into its surface is called hardness. Different hardness testing methods have different hardness standards. Commonly used hardness indicators include Mohs hardness, Brinell hardness, Rockwell hardness, and Vickers hardness, etc. Mohs hardness, also known as Mohs scale of hardness, is a method of using a pyramidal diamond indenter to scratch the surface of the tested mineral and measuring the depth of the scratch. This scratch depth is the Mohs hardness, denoted by the symbol HM. Mohs hardness can be divided into ten levels, from hard to soft in turn: diamond (10), corundum (9), topaz (8), quartz (7), feldspar (6), apatite (5), fluorite (4), calcite (3), gypsum (2), talc (1).

[0038] The anti-glare coating provided by the present invention, by adding a nano-ceramic polymer material to the anti-glare coating, after spraying onto the glass surface and then through high-temperature sintering, after the solvent volatilizes, silicon dioxide, nano-ceramic polymer material and a small amount of fillers can be left on the glass surface, and the molecular structure is dense, so that the glass surface can achieve the effects of high wear resistance and high hardness.

[0039] In some alternative embodiments, the mass percentage content of silicon dioxide is 10%-15%, the mass percentage content of alkyd resin is 15%-25%, the mass percentage content of nano-ceramic polymer material is 35%-40%, the mass percentage content of diluent is 10%-20%, the mass percentage content of fluoride is 2%-5%, and the mass percentage content of polytetrafluoroethylene is 3%-8%.

[0040] Exemplarily, any value within the range of 10%-15% for the mass percentage content of silicon dioxide, for example, the mass percentage content of silicon dioxide is 10%, 13% or 15%, etc., and any value within the range of 35%-40% for the mass percentage content of nano-ceramic polymer material, for example, the mass percentage content of nano-ceramic polymer material is 35%, 36% or 40%, etc.

[0041] In this embodiment, by limiting the mass percentage content of the nano-ceramic polymer material to 35%-40%, while improving the scratch resistance of the glass surface, the bonding force between the anti-glare coating and the glass surface can be ensured.

[0042] In some alternative embodiments, the particle size of the nano-ceramic polymer material is 50 nm - 100 nm. Exemplarily, the particle size of the nano-ceramic polymer material can be any value within 50 nm - 100 nm. For example, the particle size of the nano-ceramic polymer material can be 50 nm, 60 nm, 70 nm, 90 nm, or 100 nm.

[0043] Specifically, the nano-ceramic polymer material is made into a material with a particle size of 50 nm - 100 nm. An alkyd resin is added as a filler to the nano-ceramic polymer material and silica particles, and a diluent and an auxiliary solvent are added, and then stirred to generate an anti-glare coating.

[0044] In this embodiment, by limiting the particle size of the nano-ceramic polymer material to 50 nm - 100 nm, the nano-ceramic polymer material can be uniformly dispersed in the solvent, avoiding agglomeration or deposition of the nano-ceramic polymer material.

[0045] The embodiment of the present invention also provides a method for preparing an anti-glare glass. It should be noted that the steps shown in the flowchart of the drawings can be executed in, for example, an anti-glare glass preparation device, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0046] In this embodiment, a method for preparing an anti-glare glass is provided, which can be used in an anti-glare glass preparation device. Figure 1 is a schematic flowchart of the method for preparing an anti-glare glass according to the embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0047] Step S101, spraying the coating on the surface of the glass substrate to form an anti-glare coating.

[0048] Among them, the coating is the anti-glare coating provided in any of the above embodiments.

[0049] Specifically, after providing the glass substrate, the anti-glare coating is sprayed on the selected surface of the glass substrate through a spraying device to form an anti-glare coating. Exemplarily, the spraying device can be a spray gun or a butterfly atomizer, etc.

[0050] Step S102, performing tempering treatment on the glass substrate sprayed with the anti-glare coating to obtain the anti-glare glass.

[0051] Specifically, the toughening treatment is a process of physically or chemically processing glass to form a compressive stress on the glass surface and improve the strength of the glass. Physical toughening is to heat the glass to an appropriate temperature and then quickly cool it, causing the glass surface to shrink rapidly, generating a compressive stress. The middle layer of the glass cools more slowly and has not had time to shrink, enabling the glass to obtain higher strength. Chemical toughening is to change the surface composition of the glass through chemical methods (such as ion exchange) to increase the compressive stress in the surface layer, thereby increasing the strength and stability of the glass.

[0052] Exemplarily, the glass substrate sprayed with an anti-glare coating can be toughened by physical toughening or by chemical toughening.

[0053] According to the method for preparing anti-glare glass provided in this embodiment, first, an anti-glare coating is sprayed on the surface of the glass substrate to form an anti-glare coating, and then the glass substrate sprayed with the anti-glare coating is toughened to obtain anti-glare glass. In the present invention, spraying is performed first and then toughening. The temperature during the toughening treatment can make the glass substrate and the anti-glare coating in a softened state, thereby improving the adhesion and making it easier and more firm to combine the anti-glare coating and the glass substrate together.

[0054] In this embodiment, a method for preparing anti-glare glass is provided, which can be used in a device for preparing anti-glare glass. Figure 2 It is a schematic flow chart of another method for preparing anti-glare glass according to an embodiment of the present invention, as Figure 2 shown, and the method includes the following steps:

[0055] Step S201, cleaning the glass substrate.

[0056] Among them, the cleaning treatment includes at least one of cleaning treatment, plasma treatment, or corona treatment.

[0057] Exemplarily, the cleaning treatment is specifically to clean the glass substrate through a cleaning machine (such as an ultrasonic cleaning machine, a brush cleaning machine, etc.) or a solvent (such as a weak alkaline cleaning agent or solvent, a strong alkaline cleaning agent, etc.) to remove dust, oil stains, and other stains on the surface of the glass substrate, making the surface of the glass substrate hydrophilic. The plasma treatment is specifically to bombard the glass substrate with a plasma surface treatment machine to perform certain physical and chemical modification on the glass substrate and improve the adhesion of the glass substrate surface. The corona treatment is specifically to use high-frequency high-voltage electricity to generate corona discharge on the surface of the glass substrate to generate low-temperature plasma, making the surface of the glass substrate have higher adhesion.

[0058] In this embodiment, before spraying, cleaning the glass substrate can change the surface tension of the glass, making it easier for the anti-glare coating and the glass substrate to combine.

[0059] Step S202: Spray a coating material onto the surface of the glass substrate through a spraying device to form an anti-glare coating.

[0060] Specifically, step S202 is a specific implementation manner of step S101 in the above Figure 1 illustrated embodiment.

[0061] Among them, the pressure of the nozzle of the spraying device is 4 Mpa - 8 Mpa, the flow rate of the nozzle is 900 g / min - 1500 g / min, and the belt transmission speed of the spraying device is 300 mm / min - 600 mm / min.

[0062] Specifically, the pressure of the nozzle can be any value within 4 Mpa - 8 Mpa. For example, the pressure of the nozzle can be 4 Mpa, 6 Mpa, or 8 Mpa. The flow rate of the nozzle can be any value within 900 g / min - 1500 g / min. For example, the flow rate of the nozzle can be 900 g / min, 1000 g / min, 1200 g / min, or 1500 g / min. The belt transmission speed of the spraying device is any value within 300 mm / min - 600 mm / min. For example, the belt transmission speed of the spraying device can be 300 mm / min, 400 mm / min, 500 mm / min, or 600 mm / min, etc.

[0063] Through the above settings, the anti-glare coating material containing silica particles and nano-ceramic polymer materials can be dispersed into uniform and fine droplets and evenly coated on the surface of the glass substrate.

[0064] Step S203: Temper the glass substrate sprayed with the anti-glare coating through a tempering furnace to obtain anti-glare glass.

[0065] Specifically, step S203 is a specific implementation manner of step S102 in the above Figure 1 illustrated embodiment.

[0066] Among them, the tempering temperature is 600°C - 700°C, and the tempering duration is 5 min - 10 min.

[0067] Specifically, the tempering temperature can be any value within 600°C - 700°C. For example, the tempering temperature can be 600°C, 620°C, 650°C, or 700°C, etc. The tempering duration can be 5 min - 10 min. For example, the tempering duration can be 5 min, 6 min, 8 min, or 10 min, etc.

[0068] The tempering temperature of 600°C - 700°C can make the glass substrate and the anti-glare coating in a softened state, enabling the glass substrate and the anti-glare coating to be better combined together.

[0069] Step S204, perform cleaning treatment, printing treatment, and baking treatment on the anti-glare glass.

[0070] Exemplarily, the anti-glare glass can be cleaned by a cleaning device such as an ultrasonic cleaning machine or a brush cleaning machine. Printing treatment can be performed on the surface of the glass substrate away from the anti-glare coating. For example, screen printing is performed on the surface of the glass substrate away from the anti-glare coating to form a screen printing ink layer for decorating the glass substrate. After cleaning and printing are completed, baking treatment can be performed on the anti-glare glass. Among them, the baking temperature is 180°C - 250°C, and the baking duration is 30 min - 50 min.

[0071] Specifically, the baking temperature can be any value within 180°C - 250°C, such as 180°C, 200°C, 220°C, or 250°C, etc. The baking duration can be any value within 30 min - 50 min, such as 30 min, 35 min, 40 min, or 50 min, etc.

[0072] Step S205, inspect whether the anti-glare glass is qualified.

[0073] Specifically, devices such as a camera can be used to perform an appearance inspection on the anti-glare glass to inspect whether the anti-glare glass is qualified. Exemplarily, when there are no defects in the appearance of the anti-glare glass, the anti-glare glass is qualified; when there are defects in the appearance of the anti-glare glass, the anti-glare glass is unqualified. By inspecting whether the anti-glare glass is qualified, it is possible to prevent defective anti-glare glass from leaving the factory and affecting the product qualification rate.

[0074] In the preparation method of the anti-glare glass provided in this embodiment, before spraying, cleaning treatment is performed on the glass substrate, which can enable better bonding between the glass substrate and the anti-glare coating. After tempering, cleaning treatment, printing treatment, and baking treatment are performed on the glass substrate for the anti-glare glass, which can improve the aesthetics of the anti-glare glass. Inspecting whether the anti-glare glass is qualified can improve the factory qualification rate of the anti-glare glass.
