Blue-ray-filtering anti-glare abrasion-resistant mobile phone covering plate and preparation method thereof

Abstract

The invention discloses a blue-ray-filtering anti-glare abrasion-resistant mobile phone covering plate and a preparation method thereof. The blue-ray-filtering anti-glare abrasion-resistant mobile phone covering plate comprises a base plate. A first film layer, a second film layer, a third film layer, a fourth film layer, a fifth film layer, a sixth film layer, a seventh film layer and an eighth film layer are sequentially arranged on the outer surface of the base plate from inside to outside. The first film layer, the fourth film layer and the sixth film layer are titanium oxide layers and 10-100 nm thick. The second film layer, the fifth film layer and the seventh film layer are silicon dioxide layers and 50-100 nm thick. The third film layer is a metal layer and 5-20 nm thick. The eighth film layer is a high-hardness layer and 10-50 mm thick. The preparation method includes the following steps that (1) the outer surface of the base plate is cleaned, and (2) the films are plated on the outer surface of the base plate. The mobile phone covering plate can effectively filter out more than 33% of harmful blue ray, and can effectively relieve vision fatigue due to filtering of the harmful blue ray and glaring light, and the abrasion resistance of the mobile phone covering plate is obviously improved due to the adopted high-hardness layer.

Description

technical field [0001] The invention relates to the technical field of a mobile phone cover, in particular to a wear-resistant mobile phone cover for filtering blue light and anti-glare and a preparation method thereof. Background technique [0002] With the progress of society and the development of science and technology, mobile phones have widely entered people's work and life. At present, the blue light, ultraviolet rays, and glare emitted by the screens of mobile phones on the market are more and more harmful to eyesight. [0003] Blue light is high-energy visible light with a wavelength of 400-500nm. Blue light can directly penetrate the cornea, eye lens, and reach the retina. The retinal pigment epithelial cells have a strong absorption effect on the light radiation in the blue light area, and the absorption of blue light radiation will cause the retinal pigment epithelial cells to shrink, which is also one of the main causes of macular degeneration; the higher the bl...

AI Technical Summary

Problems solved by technology

Therefore, a mobile phone screen cover with filtering harmful blue light has appeared on the market, but the existing mobile phone screen cover is easy to be scratched or scratched during use, which affects the appearance. What's more, the mobile phone screen cover After the surface is scratched or rubbed, the inner layer is exposed to the air, which is easily corroded and affects the service life

In addition, the existing mobile phone screen covers rarely have a bactericidal function, and people are easy to infect bacteria from the mobile phone screen cover during use, causing harm to the human body
