Embodiment 2

[0039] Embodiment 2, as attached figure 2 As shown, the superhard anti-reflection film is coated on the glass substrate, and the material of the film system is SiO 2 、Si 3 N x and SiN x o y One or more of them are stacked or staggered. The reference wavelength of the film system is λc=550nm, and there are 8 layers in total including the modified polyfluorosilane layer. During the specific production, the anti-reflection layer formed in the optical coating, the optical function Layer or decorative functional layer is made of Si, SiO 2 、Si 3 N x and SiN x o y One or more of them are alternately plated in 7 layers, and then thermally evaporated or sprayed with modified polyfluorosilane to form a waterproof and oil-proof functional layer on the film layer. The layout and physical thickness of each layer of the film system in this embodiment are shown in the table 2:

Abstract

The invention discloses an optical film with the characteristics of high hardness, strong adhesive force and wear resistance, the optical film sequentially comprises a substrate layer, an optical coating and a waterproof and oil-proof coating from bottom to top in a use state, the optical coating is made of one or more of Si, SiO2, Si3Nx and SiNxOy, x is equal to 0-4, y is equal to 0-2, and the waterproof and oil-proof coating is made of modified polyfluorosilane. And the substrate layer is made of optically processed glass, ceramic, sapphire or high-molecular polymer. The waterproof and oil-proof coating is composed of modified polyfluorosilane, the chemical formula of the modified polyfluorosilane layer is (C-F-Si) n, and the thickness of the modified polyfluorosilane layer is 1-1000 nm. Compared with the prior art, the film is used in the fields of mobile phone screen cover plates, touch panels and special lenses, the hardness is high, the film layer is not prone to cracking, and the friction resistance is good.

Description

technical field [0001] The invention relates to the technical field of optical film manufacturing, in particular to an optical film with high hardness, strong adhesion and wear resistance, which is widely used in mobile phone camera covers, smart wearable appearance parts, mobile phone screen covers, and smart wearable covers , smart wearable protective film, special lens, window panel, touch panel and instrument protection window and other places that require high film. Background technique [0002] At present, for smart terminals, especially mobile phones, tablet computers, laptops, projectors, instrument protection windows and special lenses, coating technology is often used to improve product relationship characteristics to achieve special optical functions (such as anti-reflection, beam splitting, beam splitting, cut-off, etc.) ) and decoration. In order to solve the impact of friction, scratches, friction and wear of dust particles, keys, and other hard objects in the...
