Description

Technical Field

[0001] The present application relates to the field of optical protective films, and more specifically, to an anti-glare hardened film and electronic equipment. Background Art

[0002] Anti-glare film can effectively reduce the reflection of ambient light and improve the clarity and contrast of the display image, so it is widely used in various electronic devices such as mobile phones, tablets, TVs, etc. However, anti-glare film is often exposed to contact and friction during use, and its surface is easily worn, affecting its use effect and life. The surface wear resistance of current anti-glare film is difficult to meet the higher requirements of users.

[0003] Therefore, how to improve the wear resistance of anti-glare films is an urgent problem to be solved in the current field of optical film preparation technology. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an anti-glare hardened film and an electronic device, which have both excellent anti-glare effect and wear resistance.

[0005] In a first aspect, an embodiment of the present application provides an anti-glare hardened film, which includes a substrate layer, an anti-glare layer (AG layer) and a wear-resistant layer (HC layer) stacked in sequence from bottom to top, the anti-glare layer contains organic particles, the upper half of the organic particles protrude and are embedded in the wear-resistant layer; the thickness of the anti-glare layer is H1, the thickness of the wear-resistant layer is H2, the diameter of the organic particles is D, And X=1.5~2.0.

[0006] In the above technical solution, a wear-resistant layer is added on the surface of the anti-glare layer to improve the overall wear resistance; and by controlling the ratio of the minimum protruding height D-H1 of the organic particles in the anti-glare layer to the thickness H2 of the wear-resistant layer The anti-glare hardened film as a whole has low haze, high definition, excellent anti-glare effect and wear resistance.

[0007] Specifically, after the anti-glare coating corresponding to the anti-glare layer is coated, the organic particles have a floating phenomenon, that is, the floating height of the organic particles in the formed anti-glare layer is ≥ D-H1. If the ratio X is too high, it means that the difference between the minimum protruding height of the organic particles and the thickness of the wear-resistant layer is too large, that is, the floating height of the organic particles relative to the anti-glare layer is too large. On the one hand, it may indicate that the haze of the anti-glare hardened film is high and the anti-glare property is too strong, which will reduce the visual clarity and reduce the contrast and resolution of the electronic device screen. On the other hand, it indicates that the surface roughness of the anti-glare hardened film is too large, which will reduce the wear resistance. If the ratio is too low, it means that the thickness of the wear-resistant layer is close to or higher than the minimum protruding height of the organic particles, that is, the floating height of the organic particles relative to the anti-glare layer is too small or does not float. Although the anti-glare hardened film may have excellent wear resistance, it has almost no anti-glare performance.

[0008] In a possible implementation, the haze of the anti-glare layer is 50-90%, and can be 60-80%;

[0011] And / or, the clarity of the anti-glare hardened film is 250-450%.

[0012] In the above technical solution, if the clarity of the anti-glare layer is too low and the haze is too high, the anti-glare property will be too strong, which may cause flash points in the coating film; if the clarity of the anti-glare layer is too high, the clarity will be greatly improved after adding a wear-resistant layer, resulting in the final finished product surface not having anti-glare properties.

[0014] And / or, the average particle size of the organic particles is 2 to 5 μm.

[0016] In a possible implementation, the thickness H1 of the anti-glare layer is 0.5-3 μm, and the thickness H2 of the wear-resistant layer is 0.3-2 μm.

[0017] In the above technical solution, by selecting a suitable film thickness, the surface of the anti-glare hardened film has a sufficient concave-convex structure to provide haze and anti-glare properties.

[0020] The photoinitiator includes one or more of 1-hydroxycyclohexyl phenyl ketone, 2-methyl-1-(4-methylthiophenyl)-2-morpholinyl-1-propanone, benzoin dimethyl ether, xylene ketone, 2-isopropylthioxanthone, 2,4,6 (trimethylbenzoyl) diphenylphosphine oxide, and TPO;

[0021] The organic solvent includes one or more of ethyl acetate, butyl acetate, methyl ether, propylene glycol methyl ether, methyl isobutyl ketone, butanone, cyclohexanone, n-butanol, n-propanol, isopropanol, toluene and xylene.

[0081] (3) Film coating:

[0082] A PET base film with a thickness of 50 μm was selected as the substrate layer. The anti-glare coating was firstly coated on one surface of the substrate layer and photocured to form an anti-glare layer. Then, a wear-resistant coating was coated on the surface of the anti-glare layer and photocured to form a wear-resistant layer to obtain an anti-glare hardened film.

[0083] The differences between the embodiments and the comparative examples are shown in Table 1 below.

[0084] Table 1 Differences between Examples and Comparative Examples

[0085]

[0086] The anti-glare hardened films of various embodiments and comparative examples were tested and analyzed.

[0087] 1. Adhesion test method:

[0088] According to the standard ASTMD 3359, first use a grid knife to draw a grid on the surface of the film layer, then stick 3M600 tape on the drawn grid, and then quickly tear off the tape in a 180° direction to observe the grid peeling condition.

[0089] 5B: The coating is not detached at all;

[0090] 4B: The coating peeling area is less than 5%;

[0091] 3B: The coating peeling area is 5% to 15%;

[0092] 2B: The coating peeling area is 15% to 35%;

[0093] 1B: The coating peeling area is 35% to 65%;

[0094] 0B: The coating peeling area is >65%.

[0095] 2. Anti-glare effect test method:

[0096] The prepared anti-glare hardened film is pasted on a black acrylic plate with the wear-resistant layer facing upwards. After repeated inspection under a three-wavelength lamp tube, the clearer the lamp tube outline on the film surface, the worse the anti-glare property; conversely, the better the anti-glare property.

[0097] Judgment criteria: If the outline of the lamp tube is evenly diffused, the anti-glare property is excellent, which is recorded as "◎"; if the outline of the lamp tube is vaguely visible, the anti-glare property is average, which is recorded as "△"; if the outline of the lamp tube is clearly visible, the anti-glare property is poor, which is recorded as "×".

[0098] 3. Haze test method:

[0099] The test was conducted using a NDH 2000N haze meter from Nippon Denshoku.

[0100] The haze of the anti-glare layer is also tested using this method.

[0101] 4. Clarity test method:

[0102] The transmitted image clarity of the antiglare cured film at 0.125 mm, 0.25 mm, 0.5 mm, 1.0 mm and 2.0 mm optical combs was measured by transmission measurement using an image clarity meter ICM-1T (manufactured by SUGA TEST INSTRUMENTS) in accordance with JIS K7105, and the total was calculated.

[0103] The clarity of the anti-glare layer is also tested using this method.

[0104] 5. Wear resistance test method:

[0105] Press Bonston steel wool #0000, 2cm×2cm wear-resistant head, against the coating surface of the film with a load of 1000g and move back and forth several times, then observe the damage state of the film surface and make a judgment.

[0106] The test results are shown in Table 2 below.

[0107] Table 2 Test results of various embodiments and comparative examples

[0108]

[0109]

[0110] Combining the results of Table 1 and Table 2, it can be seen that Examples 1 to 4 of the present application can significantly improve the wear resistance of the overall surface by controlling the ratio of the minimum protrusion height D-H1 of the organic particles relative to the anti-glare layer to the thickness H2 of the wear-resistant layer to 1.5 to 2.0, which can achieve 2000 times without scratches; and can also ensure low haze, high clarity, and anti-glare effect.

[0111] The ratio of Comparative Examples 1, 4 and 6 is too large, which is mainly manifested as poor wear resistance, and may also show poor haze and poor clarity; the ratio of Comparative Examples 2 to 3 and 5 is too small, which is mainly manifested as poor anti-glare effect, and may also show poor wear resistance.

[0112] In summary, the anti-glare hardened film and the electronic device according to the embodiments of the present application have both excellent anti-glare effect and wear resistance.

[0113] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application.
