Description

Technical Field

[0001] The present invention relates to the technical field of display coatings, and in particular to an antifouling coating for a display, a preparation method thereof, and a display. Background Art

[0002] To overcome inherent CRT flaws (such as glare and static electricity), large-screen monitors often use various coatings on the glass surface to provide anti-static, anti-radiation, and anti-glare properties. Monitors using these special coatings also offer high-quality images with no distortion and balanced, vibrant colors. Four common coatings are DE, AGAS, ARAS, and UC.

[0003] The DE (Direct Etching) coating directly carves the screen surface into an uneven shape, thereby weakening light reflection and reducing light interference.

[0004] AGAS (Anti-Glare Anti-Static: anti-glare, anti-static) coating is a silicone coating that evenly covers the surface of the screen to diffuse reflected light, and the conductive particles contained in this coating can play an anti-static role.

[0005] ARAS (Anti-Reflection Anti-Static: anti-reflection, anti-static) coating is a multi-layer coating that can effectively prevent light reflection, making the picture clearer and brighter.

[0006] UC (UltraClear) coating is a multi-layer composite coating that effectively prevents image distortion and improves color balance, while also effectively suppressing various interferences. This minimizes the dizziness and vision damage caused by the unique brightness of cathode ray tubes.

[0007] However, current coatings rarely have all the characteristics of transmittance, hardness and water contact angle, which results in the coating having a dark display effect on the screen, being easily scratched and having poor anti-fingerprint effect.

[0008] In view of this, the present invention is proposed. Summary of the Invention

The prepared antifouling coating for displays has extremely strong adhesion to display screens (glass, polycarbonate, PET, etc.), can quickly form a film on the surface of the display, and the coating has a thickness of 0.5-0.8 μm and a light transmittance greater than 95%. The coating reaches a hardness of 6H after film formation and has an extremely high water contact angle (>140°). DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer are used. Where the manufacturer of the reagents or instruments is not specified, all are conventional products that can be purchased commercially.

[0035] The invention provides an antifouling coating for displays. The raw materials thereof comprise, by mass percentage, 88%-95% of fluorosilicone resin, 1%-8% of active diluent, 3%-5% of coupling agent and 1%-3% of initiator.

[0041] From the selection of the fluorosilicone resin and the reactive diluent in the present invention, it can be seen that the fluorosilicone resin contains fluorocarbon chains and silicon groups, and the reactive diluent also contains fluorocarbon chains.

[0090] Experimental example

[0091] The antifouling coatings for displays prepared in Examples 1-6 and Comparative Examples 1-6 were applied to the surface of a display. After application, the transmittance, hardness, and water contact angle were measured. The transmittance was measured using the method described in GB / T 2410-2008, "Determination of light transmittance and haze of transparent plastics"; the hardness was measured using the pencil method described in GB / T 6739-2022, "Determination of film hardness by the paint and varnish pencil method"; and the water contact angle was measured using the methods described in GB / T 30447-2013, "Measurement of contact angle of nanofilms" or GB / T 30693-2014, "Measurement of contact angle of plastic films with water." The test results are as follows:

[0092] Example Coating thickness / μm Transmittance / % Paint film hardness Water contact angle / ° Example 1 0.5 97 >6H 160 Example 2 0.58 97 >6H 145 Example 3 0.77 96 >6H 146 Example 4 0.6 97 >6H 155 Example 5 0.8 95 >6H 162 Example 6 0.8 95 >6H 140 Comparative Example 1 0.5 87 5H 106 Comparative Example 2 0.5 91 5H 105 Comparative Example 3 0.5 94 2H 128 Comparative Example 4 0.5 96 5H 124 Comparative Example 5 0.5 82 4H 110 Comparative Example 6 0.5 85 2H 133

[0093] As can be seen from the table above, the thermally cured and cross-linked fluorosilicone resin exhibits extremely high water contact angles and film hardness. Furthermore, the presence of silicon groups as the backbone structure significantly increases the film's light transmittance and hardness, while also helping to improve adhesion.

[0094] Specifically, Examples 1-6 of the present invention all have extremely high light transmittance, paint film hardness and water contact angle. In Comparative Example 1, a conventional method is used to prepare fluorosilicone resin, and its light transmittance, paint film hardness and water contact angle are significantly lower than those of Example 1. The reason is that the main chain is a hydrocarbon chain and all functional groups are in the side chain. The mass ratio of hydrogenated silicone oil to fluoroalkyl vinyl ether in Comparative Examples 2 and 3 is not within the range of 1:2-8 of the present application. When the amount of fluoroalkyl vinyl ether is too low, the light transmittance, paint film hardness and water contact angle will be significantly reduced. When the amount of fluoroalkyl vinyl ether is too high, not only will the performance not be improved, but the light transmittance, paint film hardness and water contact angle will be reduced, especially the paint film hardness can only reach 2H. The use of other active diluents that do not contain fluorocarbon chains in Comparative Example 4 will result in poor curing and cross-linking effects of the system and affect the performance of the fluorosilicone resin, thereby reducing light transmittance, paint film hardness and water contact angle. In Comparative Examples 5 and 6, the dosage of the raw materials was adjusted, especially the dosage of the fluorosilicone resin was too little or too much, which resulted in the effect being significantly worse than that of Example 1.

[0095] In summary, the antifouling coating for displays provided by the present invention is prepared by combining a fluorosilicone resin of a specific structure with an active diluent, a coupling agent and an initiator, wherein the fluorosilicone resin contains both a fluorocarbon chain and a silicon base. The fluorosilicone resin of this structure forms a dense film after heat curing and cross-linking, and the fluorine-containing segments aggregate on the surface during film formation to provide anti-fouling ability. The introduction of silicon improves adhesion while reducing crystallinity and improving transmittance. The preparation method of the antifouling coating for displays provided by the present invention is simple and easy to operate. The prepared antifouling coating for displays has extremely strong adhesion to display screens (glass, polycarbonate, PET, etc.), can quickly form a film on the surface of the display, with a coating thickness of 0.5-0.8μm and a light transmittance greater than 95%. The coating reaches a hardness of 6H after film formation and has an extremely high water contact angle (>140°).

[0096] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
