Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of high use cost, low visible light transmittance, and high visible light reflectance existing in existing ultraviolet blocking materials, and provide an anti-ultraviolet anti-reflection film and its application. The film will have different The layers of dielectric materials with refractive index are superimposed alternately. Using the different reflection and refraction effects of light waves with different wavelengths at the interface between different dielectric material layers, it has an excellent reflection effect on ultraviolet light and reduces the reflectivity of visible light. , improve the visible light transmittance of the monolithic glass, so that the film layer can achieve the function of anti-ultraviolet and anti-reflection

Abstract

The invention discloses an anti-ultraviolet anti-reflection film layer and an application thereof. The film layer is composed of a high refractive index dielectric material layer (21) and a low refractive index dielectric material layer (22) alternately, wherein the total number of layers of the high refractive index dielectric material layer (21) and the low refractive index dielectric material layer (22) is not less than 8; the high refractive index dielectric material layer (21) has a refractive index of not less than 2.10 for visible light having a wavelength of 550 nm; and the low refractive index dielectric material layer (22) has a refractive index of not more than 1.52 for visible light having a wavelength of 550 nm. The film layer provided by the invention, by utilizing the effects of reflection and refraction of light waves of different wavelengths at different dielectric material layers, has excellent reflection effect for ultraviolet light, reduces the reflectivity of visible light at the same time, and increases the visible light transmittance of the film layer, so that the film layer achieves anti-ultraviolet anti-reflection effect.

Description

technical field [0001] The invention relates to the field of optical film materials, in particular to an anti-ultraviolet anti-reflection film and its application. Background technique [0002] The solar spectrum is a continuous spectrum with different wavelengths, divided into two parts, visible light and invisible light. Visible light has a wavelength of 400-760nm. After scattering, it can be divided into seven colors: red, orange, yellow, green, blue, blue, and purple. When gathered together, it becomes white light. Invisible light can be divided into two types: the infrared ray, which is located outside the red light area, has a wavelength greater than 760nm; the ultraviolet ray, which is located outside the purple light area, has a wavelength of 290-400nm. The strict wavelength range of ultraviolet light is divided into three bands from 100nm to 400nm, namely short-wave ultraviolet (UVC) with a wavelength of 100-290nm, medium-wave ultraviolet (UVB) with a wavelength of...
