Description

Technical Field

[0001] The utility model belongs to the technical field of float glass, and particularly relates to a wear-resistant float glass. Background Art

[0002] Float glass is a flat glass manufacturing process. The key in the production process of float glass is to use a tin bath to cool and form the molten glass liquid, so that the glass plate floats on the tin surface to form a uniform thickness. The glass produced by this process has high transparency and flatness, and is widely used in industries such as construction and automobiles.

[0003] Due to the uniqueness of the float process, the glass surface is very flat, without the corrugations or unevenness common in traditional manufacturing methods. The float process ensures that the thickness of the glass sheet is very uniform, reducing the stress and cracking risks caused by uneven thickness. There are no bubbles and impurities in the production process of float glass, so it has high transparency. Float glass has a certain mechanical strength and can withstand a certain amount of pressure and impact.

[0004] Traditional float glass also has some defects and limitations. The surface of traditional float glass is relatively soft, not wear-resistant, and is easily scratched and worn, especially in a harsh use environment. In the prior art, a wear-resistant high-transparency float glass and its preparation method with the publication (announcement) number: CN109824274A includes a glass substrate, a transition layer, and a wear-resistant layer. The transition layer is an alumina film layer, and the wear-resistant layer is a spherical nano-silica sol layer to improve the wear resistance.

[0005] However, the float glass with a glass substrate, a transition layer, and a wear-resistant layer has certain defects in terms of wear resistance, weather resistance, chemical stability, stain resistance, etc. The wear-resistant layer of float glass usually adopts a spherical nano-silica sol layer, and the wear resistance of this material is relatively low, and scratches and wear are likely to occur during use, affecting the service life and aesthetics of the glass. In addition, the transition layer of traditional float glass is an alumina film layer, and the thermal stability and chemical stability of this material are relatively poor, and damage is likely to occur in a high-temperature or chemical corrosion environment. In addition, the smooth surface characteristics of float glass make it easy for dust and stains to adhere and difficult to clean. Although float glass has a certain strength, it may still break under severe impact, posing a threat to personal safety. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art, the utility model proposes a wear-resistant float glass.

[0007] To achieve the above object, the utility model provides the following technical solutions:

[0008] A wear-resistant float glass comprises a base layer, and two surfaces of the base layer are respectively provided with a multi-layer protective coating A and a multi-layer protective coating B;

[0009] The multi-layer protective coating A is a nano-wear-resistant layer A, a transparent protective layer A, a hardness-enhancing layer A and an anti-fouling layer A coated on one side of the base layer from inside to outside in sequence;

[0010] The multilayer protective coating B is a nano-wear-resistant layer B, a transparent protective layer B, a hardness-enhancing layer B and an anti-fouling layer B which are sequentially coated from the inside to the outside on the other surface of the base layer and located away from the nano-wear-resistant layer A.

[0011] Preferably, the base layer is float glass. High-quality float glass is used as the base material of the wear-resistant float glass to ensure the flatness and strength of the entire glass.

[0012] Preferably, the nano-wear-resistant layer A and the nano-wear-resistant layer B are both made of high-performance resin material as the base material and polymerized with nano-grade ceramic powder, and have excellent wear resistance and adhesion, and can effectively improve the wear resistance of float glass.

[0013] Preferably, the transparent protective layer A and the transparent protective layer B are both made of transparent high molecular polymer as the base material, and are polymerized by adding nano fillers and stabilizers, which play the role of protecting the nano wear-resistant layer and improving the weather resistance and chemical stability of the overall glass.

[0014] Preferably, the hardness strengthening layer A and the hardness strengthening layer B are both made of high-performance resin material as a base material, and are polymerized by adding a hardener and a nano filler, so as to further improve the hardness and wear resistance of the float glass.

[0015] Preferably, the antifouling layer A and the antifouling layer B are both made of a resin with low surface energy as a base material, and are polymerized by adding nano fillers and low surface energy agents. They have excellent waterproof, oil-proof, anti-fingerprint and other properties, making the float glass easy to clean and maintain.

[0016] Preferably, an optical anti-reflection layer is disposed inside the anti-fouling layer A and the anti-fouling layer B, respectively.

[0017] Preferably, a reflective layer is provided between the transparent protective layer A and the hardness-enhancing layer A, and between the transparent protective layer B and the hardness-enhancing layer B.

[0018] Preferably, an antistatic layer is disposed on the outer sides of the antifouling layer A and the antifouling layer B, respectively.

[0019] Compared with the prior art, the technical effects and advantages of the utility model are:

[0020] This wear-resistant float glass works by coating multiple protective coatings on both sides of the base layer. These protective coatings include a nano-wear-resistant layer, a transparent protective layer, a hardness reinforcement layer, and an anti-fouling layer. A composite material with a multi-layer structure is formed, and these coatings work together to provide excellent wear resistance, hardness, scratch resistance, weather resistance, chemical resistance, and anti-fouling effects, making the glass suitable for various environments with high-performance requirements.

[0021] The nano-wear-resistant layer utilizes nanotechnology to form a composite material with a highly cross-linked structure by adding nano-scale ceramic powders (such as silica, zirconia, silicon carbide, or alumina) to the resin. This structure combines the flexibility of the resin and the hardness of the nanoparticles, significantly improving the wear resistance, hardness, and scratch resistance of the coating. It provides basic wear protection to prevent the underlying material from being worn.

[0022] The transparent protective layer provides additional protection against damage to the wear-resistant layer. It is usually composed of high molecular polymers (such as polysiloxane, polyester, polyurethane, or epoxy resin), and these polymers have good transparency and mechanical properties. During the preparation process, additives such as nano-fillers, ultraviolet absorbers, light stabilizers, and desiccants are added to improve the hardness and weather resistance of the coating. The transparent protective layer can not only protect the underlying material but also improve the overall weather resistance, chemical resistance, and mechanical properties of the material.

[0023] The hardness reinforcement layer provides further hardness and wear resistance. It is usually composed of high-hardness inorganic substances or high-performance resins, and its performance is improved by adding nano-fillers and hardeners. This helps to resist more severe wear and scratches while maintaining a certain flexibility and adhesion of the coating.

[0024] The anti-fouling layer uses low surface energy resins to reduce the adhesion of stains, liquids, or biological particles on the coating surface. It is usually composed of materials such as polysiloxane, polyvinyl fluoride, or polyurethane, and low surface energy agents such as perfluoroalkyl acrylate are added. The anti-fouling layer can effectively make the surface easy to clean and provide long-term anti-fouling effects. Description of the Drawings

Specific implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The following is a further detailed description in conjunction with the attached Figures 1 - 3 This application will be further described in detail.

[0031] An embodiment of the present application discloses a wear-resistant float glass, including a base layer 1, and multi-layer protective coatings A 2 and multi-layer protective coatings B 3 are respectively provided on both sides of the base layer 1;

[0032] The multi-layer protective coating A 2 is a nano wear-resistant layer A 21, a transparent protective layer A 22, a hardness strengthening layer A 23, and an anti-fouling layer A 24 sequentially coated from the inside to the outside on one side of the base layer 1;

[0033] The multi-layer protective coating B 3 is a nano wear-resistant layer B 31, a transparent protective layer B 32, a hardness strengthening layer B 33, and an anti-fouling layer B 34 sequentially coated from the inside to the outside on the other surface of the base layer 1 and on the side facing away from the nano wear-resistant layer A 21.

[0034] This wear-resistant float glass is respectively provided with multi-layer protective coatings A 2 and multi-layer protective coatings B 3 on both sides of the base layer 1, forming a double-sided wear-resistant float glass. This float glass can be used for glass curtain walls, doors and windows of high-rise buildings, etc., to improve the durability and safety of buildings. It is used to make high-grade glass furniture, such as table tops, cabinet doors, etc., to improve the service life and aesthetics of furniture. It is used for window glass of transportation tools such as high-speed rails, subways, and ships to ensure excellent wear resistance and line-of-sight clarity in harsh environments. As a double-sided glass component of a solar photovoltaic panel, it is not only wear-resistant, but also can improve the efficiency and life of the photovoltaic component. It is used as the glass material for displays and protective screens, providing good wear resistance and optical properties.

[0035] The base layer 1 is float glass. High-quality float glass is used as the base material of the wear-resistant float glass to ensure the flatness and strength of the overall glass.

[0036] The nano wear-resistant layer A21 and nano wear-resistant layer B31 are usually based on high-performance resin materials, which can be silicone, epoxy, polyester, polyurethane or other special resins. Nano-scale ceramic powders such as silicon dioxide (SiO2), zirconium oxide (ZrO2), silicon carbide (SiC) or aluminum oxide (Al2O3) are added to these resins, and through special synthesis and dispersion techniques, the nano-particles are evenly dispersed in the resin matrix, thus polymerizing to form the nano wear-resistant layer.

[0037] In this process, the addition of nano-particles significantly improves the wear resistance, hardness and scratch resistance of the coating. In addition, according to needs, at least two additives such as leveling agents, anti-settling agents, anti-ultraviolet agents, curing agents and cross-linking agents may be added to improve the specific properties of the coating. The leveling agent helps the coating to level better during construction and form a uniform coating film. The anti-settling agent prevents the nano-particles from precipitating and separating during storage and use. The anti-ultraviolet agent improves the weather resistance of the coating and prevents aging and degradation caused by ultraviolet rays.

[0038] The curing agent and cross-linking agent are used for the curing reaction of the resin to form a stable network structure.

[0039] The finally formed nano wear-resistant layer is a composite material with a highly cross-linked structure, which combines the flexibility of the resin with the hardness of the nano-particles, endowing the material with excellent wear resistance.

[0040] The transparent protective layer A22 and transparent protective layer B32 are usually based on transparent polymer materials. These polymer materials are one of polysiloxane, polyester, polyurethane. Polysiloxane is one of the most commonly used substrates because of its excellent weather resistance, temperature resistance and good chemical stability. Polyester resin has good transparency and gloss, as well as good weather resistance and mechanical properties. Polyurethane is a multi-functional polymer material with good wear resistance, chemical resistance and elasticity.

[0041] In the preparation process of the transparent protective layer, at least 3 of nano-fillers, anti-ultraviolet agents, ultraviolet absorbers, light stabilizers, desiccants and cross-linking agents, leveling agents and matting agents are added to the substrate to improve its performance. Nano-fillers such as silicon dioxide and zirconium oxide can improve the hardness and wear resistance of the coating. The anti-ultraviolet agent is used to improve the coating's ability to resist ultraviolet radiation and prevent degradation. The ultraviolet absorber helps to absorb ultraviolet rays and reduce damage to the substrate. The light stabilizer improves the stability of the coating under light conditions. The desiccant and cross-linking agent are used to promote the curing reaction of the resin to form a three-dimensional network structure. The leveling agent improves the fluidity of the coating so that it can be evenly distributed during the coating process. If it is necessary to reduce the gloss of the coating, a matting agent may be added.

[0042] The transparent protective layer is formed through the polymerization reaction of these substrates and additives, ultimately providing a high-performance coating that is both transparent and protective. It can effectively protect the underlying nano-wear-resistant layer and endow the overall material with better weather resistance, chemical resistance, and mechanical properties.

[0043] The hardness strengthening layer A23 and the hardness strengthening layer B33 are usually based on high-hardness inorganic substances or specific high-performance resins, and their hardness and wear resistance are improved by adding specific hardeners and fillers. The following are some commonly used substrates and additives:

[0044] Substrates: zirconia (ZrO2), silica (SiO2), silicone, polyurethane. Zirconia is a very hard material and is commonly used to improve the hardness and wear resistance of the coating. Silica also has high hardness and good chemical stability. Silicone is a transparent, highly elastic polymer material with good temperature resistance and chemical resistance. Polyurethane resin has excellent mechanical properties and wear resistance.

[0045] Additives: nano-fillers, hardeners, cross-linking agents, UV absorbers and light stabilizers, desiccants, and leveling agents.

[0046] Nano-fillers such as nano-zirconia, nano-silica, silicon carbide (SiC), or aluminum oxide (Al2O3), etc. These nano-fillers can greatly improve the hardness and wear resistance of the coating. Hardeners such as isocyanate compounds are used to react with the resin substrate to form a cross-linked structure, improving the hardness and strength of the coating. Cross-linking agents help to form a three-dimensional network structure and improve the overall performance of the coating. UV absorbers and light stabilizers are used to improve the stability and weather resistance of the coating under UV irradiation. Desiccants accelerate the curing process of the coating. Leveling agents improve the fluidity of the coating and ensure the uniformity of the coating.

[0047] The hardness strengthening layer is polymerized by mixing the above-mentioned substrates and additives and through specific production processes such as solvent evaporation, thermal curing, or photocuring. The coating formed in this way can provide excellent hardness and wear resistance, while also maintaining a certain degree of flexibility and adhesion, enabling it to effectively protect the underlying structural layer and extend the service life of the product.

[0048] The anti-fouling layer A24 and the anti-fouling layer B34 are usually based on resins with low surface energy, which can reduce the adhesion of stains, liquids, or biological particles on the coating surface. The following are some commonly used substrates and additives:

[0049] The substrate is one of polysiloxane, polyvinyl fluoride, polyurethane, and polyvinyl alcohol. Polysiloxane is often used as the substrate for the anti-fouling layer due to its low surface energy and good waterproof performance. Polyvinyl fluoride has an extremely low surface energy and is one of the most commonly used anti-fouling materials. Polyurethane has good mechanical properties and processability and is often used to prepare anti-fouling coatings. Polyvinyl alcohol has good coating and film-forming properties and is also used to prepare anti-fouling layers.

[0050] Additives: nano-fillers, low surface energy agents, anti-settling agents, photoinitiators, anti-ultraviolet agents, leveling agents, heat stabilizers. Nano-fillers such as nano-silica (SiO2), nano-titanium dioxide (TiO2), etc. can improve the mechanical properties and anti-fouling effect of the coating. Low surface energy agents such as perfluoroalkyl acrylate (FAA) or other perfluorinated compounds are used to reduce the surface energy of the coating and enhance the anti-fouling performance. Anti-settling agents prevent the nano-fillers from settling during storage and use. Photoinitiators are used in the photocuring resin system to initiate the polymerization reaction through light irradiation. Anti-ultraviolet agents improve the weather resistance of the coating and prevent aging and performance degradation caused by ultraviolet rays. Heat stabilizers improve the stability and durability of the coating at high temperatures. Leveling agents improve the fluidity of the coating and ensure the uniformity of the coating.

[0051] The anti-fouling layer is formed by mixing the above-mentioned substrate with additives and undergoing specific process treatments such as solvent evaporation, thermal curing, or photocuring to form a uniform coating film with low surface energy. Such a coating can effectively reduce the adhesion of various stains, oil stains, water stains, etc., making the surface easy to clean, thereby imparting long-term anti-fouling effects to the material.

[0052] This wear-resistant float glass uses double-sided wear-resistant float glass. Especially, multiple protective coatings are provided on both sides of the base layer 1, significantly improving the wear resistance, hardness, and scratch resistance of the glass. This enables the glass to be applied to the glass curtain walls, doors, and windows of high-rise buildings, enhancing its durability and safety. When applied to high-end glass furniture such as table tops and cabinet doors, the wear-resistant float glass can increase the service life of the furniture while maintaining its aesthetics. When used in the window glass of transportation vehicles such as high-speed trains, subways, and ships, it can ensure wear resistance and line-of-sight clarity even in harsh environments. As the double-sided glass component of solar photovoltaic panels, this wear-resistant float glass not only resists wear but also improves the efficiency and life of the photovoltaic module. When used as the glass material for displays and protective screens, it provides good wear resistance and optical properties.

[0053] The glass requires specific optical properties, such as increasing the light transmittance or changing the light propagation mode. The optical anti-reflection layer 4 should be provided on the inner sides of the anti-fouling layer A24 and the anti-fouling layer B34 respectively.

[0054] The glass requires specific reflection properties, such as high reflectivity or reflection at specific wavelengths. A reflective layer 5 is provided between the transparent protective layer A22 and the hardness strengthening layer A23, and between the transparent protective layer B32 and the hardness strengthening layer B33.

[0055] An antistatic layer 6 is provided on the outer sides of the antifouling layer A24 and the antifouling layer B34 respectively. The antistatic layer 6 is arranged on the outermost layer of the glass surface to prevent the generation and accumulation of static electricity. This can effectively reduce the impact of static electricity on the environment and users, and at the same time protect the coating from static damage.

[0056] By using transparent polymer materials such as polysiloxane, polyester, polyurethane, and epoxy as the substrate of the protective layer, and adding various functional additives, the coating exhibits good weather resistance, chemical resistance, and mechanical properties. The hardness strengthening layer uses high-hardness inorganic substances or high-performance resins, combined with hardeners and fillers, to greatly improve the hardness and wear resistance of the coating. Using a resin with a low surface energy as the substrate of the antifouling layer and adding specific additives can significantly reduce the adhesion of stains, liquids, or biological particles on the coating surface, making the surface easy to clean and extending the service life of the product. The materials and additives used in the abrasion-resistant float glass and its preparation method also take into account environmental factors such as weather resistance and ultraviolet resistance while improving performance, ensuring its stability and durability in various environments.

[0057] Generally speaking, this kind of abrasion-resistant float glass and its preparation method have broad application prospects, can meet the specific needs of multiple fields, and improve the performance and durability of the materials at the same time.

[0058] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
