Problems solved by technology

However, the etching method needs to be equipped with an appropriate acid solution. Not only is the process cumbersome, but also the etching waste solution needs to be treated in order to avoid the pollution of the environment by the etching waste solution, which makes the manufacturing cost high. The particles on the surface have weak adhesion and are easy to fall off, resulting in poor anti-glare effect
When polymethyl methacrylate (PMMA) and polycarbonate (PC) are used as cover plates, the anti-glare treatment method is generally coating method, but the temperature resistance of these two materials is poor, and the processing temperature during post-treatment is generally Below 110°C, resulting in poor particle adhesion and limited improvement in surface hardness

Embodiment 1

[0044] First, heat-curable silicone resin, nano-silica, aminopropyltriethoxysilane (KH-550), and aromatic hydrocarbon solvents are mixed to form a coating composition, and then the coating composition is sprayed on a high-temperature-resistant plastic substrate above to obtain a dry thickness of 3 μm; again dry the prepared coated high-temperature resistant plastic substrate at 50-100°C for 20 minutes; finally heat and cure the prepared dried coated high-temperature-resistant plastic substrate at 150-200°C The anti-glare film was obtained in 30 minutes.

Embodiment 2

[0046] First, heat-curable silicone resin, nano silicon dioxide, glycidyl ether oxypropyl trimethoxysilane (KH-560), and aliphatic hydrocarbon solvent are mixed into a coating composition, and then the coating composition is sprayed on on the high-temperature-resistant plastic substrate to obtain a dry thickness of 5 μm; again, dry the prepared high-temperature-resistant plastic substrate at 50-100°C for 22 minutes; finally, dry the prepared high-temperature-resistant coating at 150-200°C The plastic substrate was heated and cured for 34 minutes to obtain an anti-glare film.

Embodiment 3

[0048] First, heat-curable silicone resin, nano-silica, methacryloxypropyltrimethoxysilane (KH-570), and alcohol solvents are mixed to form a coating composition, and then the coating composition is sprayed on on the high-temperature-resistant plastic substrate to obtain a dry thickness of 7 μm; again, dry the prepared coating on the high-temperature-resistant plastic substrate at 50-100°C for 25 minutes; finally, dry the prepared high-temperature-resistant coating at 150-200°C The plastic substrate was heated and cured for 38 minutes to obtain an anti-glare film.

Abstract

The invention provides an anti-glare film and a preparation method thereof, the film has high adhesive force and surface hardness, and is flexible, bending-resistant and easy to process. The invention protects a composite film with an anti-glare function, the composite film comprises an anti-glare layer and a plastic substrate layer with a glass transition temperature (Tg) higher than 240 DEG C, and the anti-glare film has the advantages of high particle adhesion, high surface hardness, flexibility and easy processing. The film is particularly suitable for the field of vehicle-mounted curved display screens and foldable and rollable mobile phones.

Description

technical field [0001] The invention relates to the field of a composite film, in more detail, the invention relates to an anti-glare film and a preparation method thereof. Background technique [0002] When the display screens widely used in the field of consumer electronics are exposed to external incident light such as natural light and indoor light, light reflection will occur on the surface of the display screen, which will cause visual fatigue or dizziness, and deteriorate the clarity of the image formed on the display screen. , so surface treatment with additional functions is usually required on the surface of the optical film to reduce the negative impact of reflected light on the human eye watching the display. [0003] The industry usually performs anti-glare treatment on the surface of the display cover. At present, the commonly used cover substrates mainly include optical glass, polymethyl methacrylate (PMMA) and polycarbonate (PC). The anti-glare of optical gla...
