Problems solved by technology

[0002] Optical films are widely used in the field of optics and optoelectronics technology. Anti-reflection film is a common type of optical film. The structure of anti-reflection film in the prior art generally includes a substrate and an anti-reflection film layer arranged on the surface of the substrate. The substrate material is common It is Ge, Si, ZnS, ZnSe or chalcogenide glass, etc. The anti-reflection coating material is commonly magnesium fluoride, silicon dioxide, etc. The function of this type of anti-reflection coating is relatively simple and needs to be further improved.

Embodiment 1

[0024] Embodiment one: if figure 1 As shown, the multifunctional optical film includes a substrate 1, which also includes an anti-reflection film layer 2, a chemically added hard coat layer 3 and a physically added hard coat layer 4 that are sequentially distributed on the surface of the substrate 1 from the inside to the outside;

[0025] The anti-reflection film layer 2 is a multi-layer anti-reflection film, including a cerium oxide film layer 21, an indium tin oxide film layer 22, a silicon nitride film layer 23 and a silicon dioxide film layer 24 distributed sequentially from the inside to the outside;

[0026] The chemical hard coat layer 3 is a wear-resistant film layer made by mixing methacryloxypropyl trimethoxysilane with epoxy resin;

[0027] The physical hard coating layer 4 is a diamond film layer.

[0028] The present invention also provides a method for preparing the above-mentioned multifunctional optical film, comprising the following steps:

Embodiment 2

[0042] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that the chemical hard coat layer 3 is a UV curable film with vinyltriethoxysilane and 3-mercaptopropyltriethoxysilane as monomers . During preparation, use vinyltriethoxysilane and 3-mercaptopropyltriethoxysilane as monomers to prepare UV curing film hardening liquid, and spray the hardening liquid on the surface of the siliconized silicon film layer 24 to form a chemically hardened film. Dura layer 3.

Abstract

The invention discloses a multifunctional optical film and a production method thereof. The multifunctional optical film includes a substrate, and an anti-reflection film layer, a chemically added hard coat layer and a physically added hard coat layer which are sequentially distributed on the surface of the substrate from inside to outside; The reflection film layer is a multi-layer anti-reflection film, including cerium oxide film layer, indium tin oxide film layer, silicon nitride film layer and silicon dioxide film layer distributed sequentially from the inside to the outside; Acryloyloxypropyl trimethoxysilane as a monomer, mixed with epoxy resin to form a wear-resistant film layer; the physical hardened film layer is a diamond film layer. Chemical hard coating and physical hard coating are used to increase the hardness of the surface of the optical film. The anti-reflection coating has a four-layer structure, which has a good effect, and the cerium oxide coating makes the optical film have a higher UV absorption rate and Good thermal stability can prevent the ultraviolet aging of the optical film, and the setting of the indium tin oxide film layer makes the anti-reflection film layer have conductivity, thereby obtaining an optical film with various functions.
