Problems solved by technology

But obviously, such a measure is not only difficult to adapt to the real fogging scene, but also brings inconvenience to users
In recent years, some manufacturers have also tried to coat the surface of spectacle lenses with a durable anti-fog film, but after the lens is used, the anti-fog effect is poor, and the duration is difficult to exceed three months
The reason, on the one hand, is that the anti-fog material used is not sufficiently hydrophilic, or the hydrophilic group has high reactivity and is easily consumed by reacting with active pollutants, resulting in rapid attenuation of hydrophilicity.
On the other hand, the coating process has not been adapted to the anti-fog material, resulting in insufficient overall wear resistance of the film layer on the lens, and the anti-fog film layer and even the anti-ultraviolet, anti-blue light, anti-reflection and other films below The layer is easily worn and the effect is attenuated

Embodiment 1

[0045] Embodiment 1: A wear-resistant, anti-fog and easy-to-clean resin spectacle lens. The two surfaces of the resin lens include a five-layer structure from the inside to the outside. Three-layer composite anti-reflection coating, the fourth nano-silicon dioxide coating, and the fifth nano-superhydrophilic anti-fog coating. . First, ultrasonically clean the resin lens, then use clear water and pure water to clean the resin lens for the second time, and then immerse the resin lens in the siliconized hardening coating for 15 seconds. The siliconized hardening coating uses methyltriethoxysilane and ethyl orthosilicate as main raw materials, and uses isopropanol and deionized water as solvents, and the molar ratio of the four is 5:4:22:3. The pH value of the mixed solution is adjusted between 1.5-2 with a diluent solution of 5% hydrochloric acid in isopropanol. Stir at a constant temperature of 45°C until the mixture becomes clear, and then stand still for 2 hours. Then add l...

Abstract

The invention relates to the technical field of antifogging of resin spectacle lenses, in particular to a wear-resistant antifogging easy-to-clean resin spectacle lens and a manufacturing method thereof. The two surfaces of the resin lens comprise five layers of structures from inside to outside, namely a first silicification hardening film layer, a second nanometer aluminum oxide film layer, a third composite antireflection film layer, a fourth nanometer silicon dioxide film layer and a fifth nanometer super-hydrophilic anti-fog film layer. The manufacturing method of the wear-resistant anti-fog easy-to-clean resin spectacle lens comprises the following steps: plating a silicification hardening film layer on the resin lens; sequentially plating a nano aluminum oxide film layer, a composite anti-reflection film layer and a nano silicon dioxide film layer on the resin lens in vacuum; enhancing and activating the film layers of the resin lens; plating a nano super-hydrophilic anti-fog film layer on the resin lens and the like. Through the steps, the problems of surface fogging, blurred sight and the like under the scenes of alternate cooling and heating, hot food and hot soup during dining in winter, wearing of masks and the like of the spectacle lenses are fundamentally solved, and great convenience is brought to vast spectacle wearers.

Description

technical field [0001] The invention relates to the technical field of anti-fog coating of resin spectacle lenses, in particular to a wear-resistant, anti-fog and easy-to-clean resin spectacle lens and a manufacturing method thereof. Background technique [0002] The surface of glasses lenses is prone to fogging under scenes such as alternating hot and cold, eating hot food and hot soup in winter, and wearing a mask, which makes people "blind" instantly. This problem has been plagued by the vast number of glasses wearers. At present, there are anti-fog agents sprayed on the surface of the lens on the market, and there are also eyeglass wiping cloths that absorb anti-fog materials. After use, the glasses can obtain a short-term anti-fog effect. But obviously, such a measure is not only difficult to adapt to the real fogging scene, but also brings inconvenience to users. In recent years, some manufacturers have also tried to coat the surface of spectacle lenses with a durabl...
