Description

Technical Field

[0002] With the rapid development of the display industry, people's requirements for displays are becoming increasingly higher. Liquid crystal displays (LCDs) are very popular due to their large viewing area, excellent picture quality, and low energy consumption. The design of LCDs is also moving towards high definition and high contrast. However, because LCDs are easily affected by external light sources during use, the reflection of external light on the display surface will produce glare, affecting the visual effect. Therefore, it is necessary to apply anti-glare treatment to the surface of the display to reduce the visual perception of glare on the audience. The commonly adopted method is to cover the polarizer on the surface of the LCD with an anti-glare film. The diffuse reflection caused by light hitting the surface of the anti-glare film is used to control the degree of light scattering and suppress glare.

[0003] The existing polarizer anti-glare film assembly is a layer of hardened layer with a concavo-convex surface coated on a triacetate cellulose substrate (TAC substrate) or a polymethyl methacrylate substrate (PMMA substrate). While ensuring good adhesion, the wear resistance of this combination can only reach 10 times of friction with 1kg weight of #0000 steel wool. While improving wear resistance, it cannot guarantee good adhesion.

[0004] Therefore, how to improve the scratch resistance of the anti-glare film and ensure the structural stability of the anti-glare film while improving the scratch resistance is the technical problem that this application aims to solve. Summary of the Invention

[0011] In particular, the present invention provides a method for processing an anti-glare coating liquid, which uses the components of the anti-glare coating liquid as described above for processing, and the specific processing steps include: In a sealed container, solvent, organic particles, nano-inorganic particles, aluminate, water, and hydrochloric acid are gradually added in proportion. After the addition is completed, the container is sealed and stirred for 12 hours. During the stirring process, the temperature in the container is maintained at 20-25 degrees Celsius and the humidity in the container is maintained at 40-70%. After sufficient stirring and hydrolysis, 6-10 functional group acrylic resin, 1-4 functional group acrylic resin, photoinitiator, and leveling agent are added, and the anti-glare coating liquid is formed after stirring for 2 hours.

[0012] In particular, the present invention provides an anti-glare film comprising: a transparent substrate layer; a layer layer disposed on the transparent substrate layer; a functional coating layer disposed on the layer layer and located on a side away from the transparent substrate layer; Wherein, the functional coating is formed by coating with the anti-glare coating liquid as described above.

This improves the bonding between the transparent substrate layer, the interlayer layer, and the functional coating, and stabilizes the structure of the anti-glare film.

[0018] The technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] The present application provides an anti-glare coating liquid, which comprises the following components in parts by weight: 6-10 functional group acrylic resin: 40-50 parts; 1-4 functional group acrylic resin: 5-10 parts; Photoinitiator: 1-3 parts; Leveling agent: 0.2-1 part; Solvent: 30-50 parts; Organic particles: 1-5 parts; Nano inorganic particles: 5-10 parts; Aluminate: 0.05-0.1 parts; Water: 0.05-0.1 parts; 30-35% hydrochloric acid: 0.05-0.1 parts.

[0021] The preferred "6-10 functional group acrylic resin" can promote the curing of the coating liquid, while the "1-4 functional group acrylic resin" can improve the connection stability between it and other media (such as the layers of the anti-glare film).

[0022] The "6-10 functional group acrylic resin" is composed of the following raw materials containing different numbers of functional groups: Acrylic acid monomer: acrylic acid monomer with 6-10 functional groups; Aliphatic / aromatic polyurethane acrylate oligomer: 6-10 functional group aliphatic / aromatic polyurethane acrylate oligomer.

[0023] In other words, the 6-10 functional acrylic resin is one or more of a 6-10 functional acrylic monomer, a 6-10 functional aliphatic urethane acrylate oligomer, or a 6-10 functional aromatic urethane acrylate oligomer. These different types of compounds (monomers or oligomers) can be selected, each with a functional group count within the range of 6-10, to collectively constitute the "6-10 functional acrylic resin" system.

[0024] The "1-4 functional group acrylic resin" is composed of the following raw materials containing different numbers of functional groups: Acrylic monomers: usually contain 1-4 functional groups (such as methyl methacrylate, 1,6-hexanediol diacrylate).

[0025] Aliphatic / aromatic polyurethane acrylate oligomers: usually contain 2-4 functional groups (such as polyurethane diacrylate, tetraacrylate).

[0026] Epoxy oligomers: such as epoxy acrylates, containing 2-4 functional groups.

[0027] Acrylate oligomer: an acrylate oligomer containing 1-4 functional groups.

[0028] In other words, the 1-4 functional acrylic resin is one or more of an acrylic monomer, aliphatic urethane acrylate oligomer, aromatic urethane acrylate oligomer, epoxy oligomer, or acrylate oligomer, each with a functional group number within the range of 1-4. These different types of compounds (monomers or oligomers), each with a functional group number within the range of 1-4, can be selected to collectively constitute the "1-4 functional acrylic resin" system.

[0029] The organic particles are micron-sized particles with a particle size of 0.5-3 microns and a refractive index between 1.49-1.65; the nano-inorganic particles are nano-aluminum oxide with a particle size of 10-100 nanometers.

[0030] The aluminate used in this application is one or more of diisopropoxyethyl acetoacetate aluminate, isopropoxy distearate aluminate, (acetylacetonato) diisopropyl aluminate, bis(acetylacetonato) isopropyl aluminate, and (acetylacetonato) diisopropoxy aluminate. The introduced aluminate hydrolyzes in the presence of hydrochloric acid as a catalyst to form an alumina sol. The alumina sol forms a micro-rough surface during the coating and drying process, enhancing light scattering and thus providing an anti-glare effect. Furthermore, the formed alumina sol can be used to graft inorganic nanoparticles onto organic particles, improving the wear resistance of the functional coating.

[0031] Alumina (Al2O3) generated by the hydrolysis of aluminates usually exists in the form of sol or nanoparticles. Its surface is rich in hydroxyl groups (-OH), which can be grafted with nano-inorganic particles and organic particles, including: Chemical bonding: The hydroxyl groups on the surface of alumina can undergo condensation reactions with nano-inorganic particles (such as SiO2, TiO2, etc.) or organic particles (polymers containing functional groups such as carboxyl and amino groups) to form Al-O-Si (with SiO2) or Al-OC (with organic particles) covalent bonds; Physical adsorption: adsorption on the particle surface through hydrogen bonding, electrostatic interaction or van der Waals force to form a physical coating layer.

[0032] In the anti-glare coating liquid of the present application, this is achieved through physical adsorption. Aluminum oxide can be covered on the surface of organic particles through physical adsorption to form a core-shell structure.

[0033] In the anti-glare coating liquid of the present application, the hydrolysis of aluminate and the compounding with nano inorganic particles / organic particles can achieve the following effects: 1. Enhance interface bonding: Nano-inorganic particles (such as SiO2) are bonded to the organic matrix (such as acrylic resin) through an alumina "bridge", which reduces phase separation and improves coating uniformity.

[0034] 2. Functional collaboration: Nano-inorganic particles provide hardness and wear resistance, organic particles impart flexibility, and alumina adjusts the refractive index and light scattering properties. The combination of the three can optimize the anti-glare and wear-resistant effects.

[0035] 3. Improved stability: The grafted composite particles are more stably dispersed in the coating liquid, reducing sedimentation or agglomeration.

[0036] In addition, the specific raw materials of other components in the anti-glare coating liquid of the present application can be: The photoinitiator can be selected from benzoin and its derivatives, benzil and its derivatives, α-hydroxyalkyl phenone, α-aminoalkyl phenone, and acylphosphine oxide.

[0037] The leveling agent may be polyether modified acrylate.

[0038] The solvent used is a mixture of one or more solvents selected from butanone, methyl isobutyl ketone, ethyl acetate, butyl acetate, propylene glycol methyl ether, propylene glycol methyl ether acetate, isopropyl alcohol and isobutyl alcohol.

[0039] When preparing the anti-glare coating liquid having the above components, the specific processing steps include: In a sealed container, solvent, organic particles, nano-inorganic particles, aluminate, water, and hydrochloric acid are gradually added in proportion. After the addition is completed, the container is sealed and stirred for 12 hours. During the stirring process, the temperature in the container is maintained at 20-25 degrees Celsius and the humidity in the container is maintained at 40-70%. After sufficient stirring and hydrolysis, 6-10 functional group acrylic resin, 1-4 functional group acrylic resin, photoinitiator, and leveling agent are added, and the anti-glare coating liquid is formed after stirring for 2 hours.

[0040] When the anti-glare coating liquid is used as a functional coating to prepare an anti-glare film, it is attached to the surface of the substrate through the layered layers as an intermediate layer.

[0041] The anti-glare film of the present application may generally include: a transparent substrate layer; a layer layer disposed on the transparent substrate layer; The functional coating layer is disposed on the layer layer and located on a side away from the transparent substrate layer.

[0042] The transparent substrate is a cellulose triacetate substrate or a polymethyl methacrylate substrate, and has a thickness of 20-100 microns, a yellow-blue index of 0-2, a haze of less than 2%, a transmittance of greater than 90%, and a hardness of greater than 500 g HB.

[0043] The coating solution of the layered layers comprises the following components in parts by weight: 6-10 functional group acrylic resin: 5-15 parts; 1-4 functional group acrylic resin: 35-45 parts, the acid value of the 1-4 functional group acrylic resin in the coating solution of the layer is greater than 100; Photoinitiator: 1-3 parts; Leveling agent: 0.2-1 part; Solvent: 30-50 parts.

[0044] Anti-glare film is produced using gravure roller or slot coating. The transparent substrate layer provides support, while the layered structure enhances adhesion between the transparent substrate and the functional coating. These layers also adjust the surface energy and refractive index, while the functional coating scatters light through its surface micro-nanostructure. Furthermore, the hydrolysis of the aluminate in the functional coating allows for the grafting of inorganic nanoparticles with organic particles, enhancing the anti-glare film's wear resistance.

[0045] Taking gravure roller coating and slot-coating functional coatings as an example, the transparent substrate layer is first surface treated, such as by dust removal and corona or plasma treatment, to improve wettability and adhesion, ensuring uniformity and bonding strength of the subsequent coating. Next, the gravure roller is immersed in the layer coating tank, where excess layer coating is scraped off with a scraper. The gravure roller contacts the transparent substrate layer, transferring the coating to the substrate surface through the mesh. The coating is then cured in a drying zone to form a layered layer. Finally, the anti-glare coating liquid is injected into a slot die via a feed pump. The anti-glare coating liquid is extruded from the die slit, forming a uniform liquid film covering the layered layer surface. During the drying and curing process, the nano-inorganic and organic particles self-organize to form micron-scale surface irregularities, achieving an anti-glare effect. The drying and curing process for the anti-glare coating liquid can be performed using UV curing (wavelength 365nm, energy 500-2000 mJ / cm²) or thermal curing (60-150°C, time 1-5 minutes).

The film was then dried in a circulating oven at 70°C for 2 minutes and then irradiated with ultraviolet light at a dose of approximately 500 mJ / cm² for 10 seconds to produce the anti-glare film.
