Description

Technical Field

[0001] This application belongs to the field of display technology, and particularly relates to an anti-glare coating liquid, a preparation method thereof, an anti-glare coating, and a display. Background Art

[0002] With the advent of the information society, various sizes and types of displays have been developed for televisions, laptops, personal computers, mobile phones, clocks, picture frames, etc. However, during the use of a display, problems such as reduced adaptability due to external strong light reflection and image reflection may occur. For example, when incident light is reflected from the surface of the display in one direction, the image contrast is reduced, and the reduced image contrast causes eye fatigue or headache.

[0003] To solve this problem, a method of scattering external light by forming a rough surface is conventionally used, and an anti-glare coating structure with a fine concave-convex surface based on a transparent substrate is provided on the reflector surface. The traditional method is to achieve the concave-convex structure of the anti-glare coating surface by phase separation or mixing and coating microparticles with resin. However, this structure will be damaged when the display is scratched and cannot be restored, causing the anti-glare coating to fail. Summary of the Invention

[0004] This application provides an anti-glare coating liquid, a preparation method thereof, an anti-glare coating, and a display. The anti-glare coating liquid contains a polymer having imino and disulfide groups, and the formed anti-glare coating can achieve self-repair when scratched, avoiding the problem of anti-glare coating failure.

[0005] To achieve the above object, the technical solution is as follows:

[0006] On the one hand, this application provides an anti-glare coating liquid, including Compound I shown as follows:

[0007]

[0008] Wherein, n = 5 - 15;

[0010] In some embodiments, the anti-glare coating liquid includes anti-glare particles, the anti-glare particles include Compound I, and the radius of the anti-glare particles is 1 - 10 μm.

[0011] Second aspect, the present application provides a method for preparing an anti-glare coating liquid for preparing the above anti-glare coating liquid, including the following steps:

[0012] Provide diisocyanate, dimethylolpropionic acid and polytetramethylene ether glycol, mix and react to obtain an isocyanate group-terminated prepolymer;

[0013] React the isocyanate group-terminated prepolymer with o-aminophenyl phenyl sulfide to obtain an amino group-terminated prepolymer;

[0014] Provide aldehyde group benzoic acid and polytetramethylene ether glycol, mix and react to obtain an aldehyde group-terminated prepolymer;

[0015] Mix the amino group-terminated prepolymer and the aldehyde group-terminated prepolymer, add triethylamine and react to obtain Compound I;

[0016] Mix Compound I, the isocyanate group-terminated prepolymer and hydrazine hydrate to obtain the anti-glare coating liquid.

[0017] In some embodiments, the diisocyanate is selected from any one of diphenylmethane diisocyanate, dicyclohexylmethane diisocyanate, isophorone diisocyanate, polyisophorone diisocyanate, 1,5-naphthalene diisocyanate, toluene-2,4-diisocyanate, 1,6-hexamethylene diisocyanate, 1,4-cyclohexane diisocyanate, toluene dimethyl diisocyanate, methylene diisocyanate, ethyl phenyl diisocyanate, trimethyl hexamethylene diisocyanate, phthalic acid diisocyanate, dodecylbenzene-2,4-diisocyanate or dimethylbiphenyl diisocyanate.

[0018] In some embodiments, the molecular weight of the polytetramethylene ether glycol is 1000-3000 g / mol.

[0019] In some embodiments, the molar ratio of the diisocyanate to the polytetramethylene ether glycol is (1.5-2.5):1.

[0020] In some embodiments, the mass of the dimethylolpropionic acid is 1-10% of the total mass of the diisocyanate, dimethylolpropionic acid and polytetramethylene ether glycol.

[0021] Third aspect, the present application provides a method for preparing an anti-glare coating, including the following steps:

[0022] Provide a substrate;

[0023] Coat the anti-glare coating liquid on the surface of the substrate to form an anti-glare coating, wherein the anti-glare coating liquid is the anti-glare coating liquid in any one of the above embodiments.

[0024] In some embodiments, the coating is a wet coating.

[0025] In a fourth aspect, the present application provides an anti-glare coating prepared by the above preparation method. The haze of the anti-glare coating is 5-65%, and the transmittance is greater than or equal to 85%.

[0026] Finally, the present application also provides a display, which includes a glass substrate, an OCA layer, a transparent substrate, a PV layer, and an anti-glare coating stacked in sequence. Among them, the anti-glare coating is the anti-glare coating in any of the above embodiments.

[0027] The anti-glare coating provided by the present application includes Compound I. When the anti-glare coating is scratched, abraded, or cut, the structure of Compound I is damaged. On the one hand, since Compound I contains imino and aromatic disulfide groups, these iminos can provide unique quadruple H-bonds, and the disulfide bond and the amino group are ortho-positioned, which can form a zigzag structure. The zigzag structure is not easy to crystallize, so the H-bonds can be exchanged at room temperature to physically repair the structure of Compound I. On the other hand, due to the imine bond present in Compound I, the imino group and the aldehyde group can undergo a reversible reaction at room temperature to chemically repair the structure of Compound I. Through the self-repair of Compound I, the self-repair function of the anti-glare coating after mechanical damage can be realized, avoiding the problem that the anti-glare coating is prone to failure, saving the process of additionally setting a protective layer on the anti-glare coating, and extending the service life of the display.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0032] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. In the description of the present application, "a plurality of" means two or more, unless otherwise clearly specifically defined. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0033] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application.

[0034] First, an anti-glare coating liquid provided by an embodiment of the present application includes Compound I:

[0035]

[0036] Wherein, n = 5 to 15. It can be understood that the value of n can be any one of 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15. When the value of n satisfies the above value range, Compound I has a relatively stable structure.

[0037] R is selected from any one of methylenediphenyl, 1,6-hexyl, isophorone group, polyisophorone group, 1,5-naphthyl, 2,4-tolyl, 1,6-hexyl, 1,4-cyclohexyl, toluenedimethyl, methylene, ethylphenyl, trimethylhexamethylene, phthalic dimethyl, 2,4-dodecylphenyl or dimethylbiphenyl.

[0038] The anti-glare coating liquid is coated on a transparent substrate, and an anti-glare coating 105 can be formed after curing. When the anti-glare coating 105 is physically damaged, the structure of Compound I is damaged, and the -NH- bond and -N= bond are prone to breakage, resulting in the failure of the anti-glare coating 105. In the compound I provided in this application, an aromatic disulfide containing two amino groups is introduced into the hard segment of polyurethane during the preparation process. These amino groups can provide unique quadruple H-bonds, and the disulfide bond and the amino group are ortho-positioned, which can form a zigzag structure. The zigzag structure is not easy to crystallize. Therefore, the H-bonds can be exchanged at room temperature. When the structure of Compound I is broken, physical repair can occur spontaneously at room temperature. At the same time, after the -N= is broken, an imino group and an aldehyde group are formed. As Figure 1 shown, the imino group and the aldehyde group can undergo a reversible reaction at room temperature and recombine to form a complete polymer structure, achieving rapid chemical repair within 60 s of damage.

[0039] In some embodiments, Compound I in the anti-glare coating liquid forms anti-glare particles, and the radius of the anti-glare particles is 1-10 μm. It can be understood that the radius value (unit: μm) of the anti-glare particles can be any value among 1, 2, 4, 6, 8, 10 or the range between any two values; the radius of the anti-glare particles is further preferably 1-5 μm. It can be understood that the radius value (unit: μm) of the anti-glare particles can be any value among 1, 2, 3, 4, 5 or the range between any two values. When the value of the anti-glare particles meets the above range, the comprehensive performance of the anti-glare coating 105 is better, and both the haze and the transmittance are in the ideal range.

[0040] Secondly, the embodiments of the present application provide a preparation method of the anti-glare coating liquid in any of the above embodiments, including the following steps:

[0041] S1. Provide diisocyanate, dimethylolpropionic acid, and polytetramethylene ether glycol, mix and react to obtain an isocyanate group-terminated prepolymer;

[0042]

[0043] S2. React the isocyanate group-terminated prepolymer with o-aminophenylthioether to obtain an amino group-terminated prepolymer;

[0044]

[0045] S3. Provide aldehyde group benzoic acid and polytetramethylene ether glycol, mix and react to obtain an aldehyde group-terminated

[0046] prepolymer;

[0047] S4. Mix the amino group-terminated prepolymer and the aldehyde group-terminated prepolymer, add triethylamine and react to obtain Compound (I);

[0048]

[0049] S5. Mix compound I with hydrazine hydrate to obtain an anti-glare coating solution.

[0050] In step S4, triethylamine is used to neutralize the carboxyl group in dimethylolpropionic acid. The anti-glare coating solution prepared after being neutralized by triethylamine has an ideal viscosity, can prevent corrosion at the same time, and the formed anti-glare coating 105 has mechanical stability.

[0051] In step S5, hydrazine hydrate is used to react with the residual NCO groups in the polymer, which can greatly enhance the stability of the particles.

[0052] In some embodiments, during the mixing of compound I and hydrazine hydrate, deionized water is added dropwise as a solvent to make the reaction between compound I and hydrazine hydrate more complete. In addition, using deionized water as a solvent can avoid the environmental problems caused by using organic solvents and reduce costs at the same time.

[0053] In some embodiments, the diisocyanate is selected from any one of diphenylmethane diisocyanate, dicyclohexylmethane diisocyanate, isophorone diisocyanate, polyisophorone diisocyanate, 1,5-naphthalene diisocyanate, toluene-2,4-diisocyanate, 1,6-hexamethylene diisocyanate, 1,4-cyclohexane diisocyanate, toluene dimethyl diisocyanate, methylene diisocyanate, ethyl phenyl diisocyanate, trimethyl hexamethylene diisocyanate, phthalic acid diisocyanate, dodecylbenzene-2,4-diisocyanate or dimethyl biphenyl diisocyanate.

[0054] In some embodiments, the molecular weight of polytetramethylene ether glycol is 1000 - 3000 g / mol. It can be understood that the value of the molecular weight of polytetramethylene ether glycol (unit: g / mol) can be any value among 1000, 1500, 2000, 2500, 3000 or the range between any two values. When the molecular weight of polytetramethylene ether glycol meets the above value range, the structure of the final product is relatively stable, is not easily damaged due to mechanical damage, and can ensure that the haze of the formed anti-glare coating 105 is within an ideal range.

[0055] In some embodiments, the molar ratio of the diisocyanate to the polytetramethylene ether glycol is (1.5 - 2.5):1. It can be understood that the molar ratio of the diisocyanate to the polytetramethylene ether glycol can be any value among 1.5, 1.7, 1.9, 2.1, 2.3, 2.5 or the range between any two values. When the molar ratio of the diisocyanate to the polytetramethylene ether glycol satisfies the above value range, n(NCO) / n(OH) in the final product is 1.5 - 2.5, and the antiglare particles formed within this ratio range can meet the ideal range with an adjustable haze of 5% - 65% and a transmittance ≥ 85%.

[0056] In some embodiments, the mass of the dimethylolpropionic acid is 1 - 10% of the total mass of the diisocyanate, dimethylolpropionic acid and polytetramethylene ether glycol. It can be understood that the mass percentage of the dimethylolpropionic acid can be any value among 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10% or the range between any two values. As an emulsifier, using dimethylolpropionic acid as a reactant can enable the synthesis of Compound I by emulsion polymerization. When the addition amount of dimethylolpropionic acid as an emulsifier satisfies the above ratio range, it can further control the size of the antiglare particles.

[0057] Again, the embodiments of the present application also provide a method for preparing an antiglare coating 105, including the following steps:

[0058] Provide a substrate;

[0059] Coat an antiglare coating solution on the surface of the substrate to form an antiglare coating 105.

[0060] Among them, the antiglare coating solution is the antiglare coating solution in any of the above embodiments.

[0061] In some embodiments, the substrate is a transparent substrate. Further, the material of the transparent substrate can be PET, PMMA, TAC, etc.

[0062] In some embodiments, the coating is a wet coating. Specifically, the coating method includes:

[0063] Roll coat the antiglare coating solution on the substrate, place it in an oven, set the oven temperature at 90 - 120°C, and dry solvents such as deionized water to obtain the antiglare coating 105. Using wet coating such as roll coating to remove the solvent deionized water and form the antiglare coating 105 can achieve mass production with low cost.

[0064] The embodiments of the present application also provide an antiglare coating 105 prepared by the above preparation method. The haze of the antiglare coating 105 is 5 - 65%, and the transmittance is greater than or equal to 85%.

[0065] Finally, the embodiments of the present application provide a display, such asFigure 2 As shown in Figure 2 , it includes a glass substrate 101, an OCA layer 102, a transparent substrate 103, a PV layer 104, and an antiglare coating 105. Among them, the OCA layer 102 is disposed on one surface of the glass substrate 101. The transparent substrate 103 has the same material as the base of the antiglare coating 105 and is disposed on the surface of the OCA layer 102 away from the glass substrate 101. The PV layer 104 is disposed on the surface of the transparent substrate 103 away from the OCA layer 102. The antiglare coating 105 is disposed on the side of the PV layer 104 away from the transparent substrate 103.
