Anti-reflection abrasion-resistant mobile phone cover plate capable of filtering out blue light and preparation method thereof

Abstract

The invention relates to the technical field of mobile phone cover plates, in particular to an anti-reflection abrasion-resistant mobile phone cover plate capable of filtering out blue light and a preparation method thereof. The mobile phone cover plate comprises a substrate. The outer surface of the substrate is sequentially provided with 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, an eighth film layer and a ninth film layer from inside to outside. The first film layer, the third film layer and the fifth film layer are all trititanium pentoxide layers, and the thicknesses of the first film layer, the third film layer and the fifth film layer are all 10-100 nm. The second film layer, the fourth film layer and the sixth film layer are all silicon dioxide layers, and the thicknesses of the second film layer, the fourth film layer and the sixth film layer are all 50-100 nm. The seventh film layer is a metal layer, and the thickness of the seventh film layer is 5-20 nm. The eighth film layer is a high-hardness layer, and the thickness of the eighth layer is 10-50 nm. The ninth film layer is an acrylic acid layer, and the thickness of the ninth film layer is 5-15 nm. The manufacturing method includes the following steps that firstly, the substrate is cleaned; secondly, the outer surface of the substrate is coated with films; and thirdly, the inner surface of the substrate is coated with films. The mobile phone cover plate can filter out harmful blue light and dazzle light, and abrasion resistance and anti-reflection performance can be improved.

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 antireflection and a preparation method thereof. Background technique [0002] With the widespread use of mobile phones in modern life, and people's lives are becoming more and more inseparable from mobile phones, many people often use mobile phones as a result of uncomfortable symptoms such as sore eyes, pain, tears, and more serious symptoms. Vision loss, these uncomfortable symptoms are caused by the harmful light emitted by the eyes on the mobile phone screen for a long time. The light emitted by the mobile phone screen is the enemy of the eyes. Color contrast and saturation will increase the brightness of the light behind the phone screen, which will make the surface of the screen appear textured like a piece of glass and improve clarity. It will also reflect light like glass, but the light shines ...

Problems solved by technology

Therefore, mobile phone screen covers have appeared in the prior art, and mobile phone screen covers can filter part of the harmful light, but the existing mobile phone covers lack the function of anti-reflection during use. In the cold winter, people carry mobile phones from When the outside enters the room, a large number of water droplets will condense on the surface of the mobile phone cover, which will affect the light transmittance of the mobile phone cover and reduce people's sight, which will not only bring great inconvenience to life, but even cause danger
