Problems solved by technology

[0003] At present, the commonly used method is to use the soaking method to put the lens into the inorganic ultrafine particles containing silicon elements. After the lens is cleaned for many times, it is immersed in the hardening solution. After a period of time, it is cured in a 100-degree oven for 2- After 3 hours, a hard coating layer is formed on the surface, but the ingredients of this hard coating solution are simple, and the silicon element contained only cannot maintain the surface hardness of the lens for a long time, and the adhesion with other coating layers is not strong afterwards. , the effect is not good

Abstract

The invention discloses a hard coating lens with relatively high sealing performance. The hard coating lens comprises a resin substrate and a hard coating film layer coated on the surface of the resin substrate, the hard coating layer is prepared from the following ingredients in parts by weight: 6 to 12 parts of molybdenum disulfide powder, 2 to 6 parts of titanium carbide powder, 3 to 7 parts of cubic boron nitride powder, 6 to 17 parts of methyltrimethoxysilane, 4 to 17 parts of silica sol, 5 to 15 parts of silane coupling agents, 10 to 15 parts of isopropanol and 80 to 120 parts of deionized water. High-hardness powder containing molybdenum disulfide powder, titanium carbide powder and cubic boron nitride powder is provided, after ball milling, methyltrimethoxysilane, silica sol, a silane coupling agent and isopropanol are mixed in deionized water to form hard coating liquid, the hard coating liquid is finally coated on the surface of the lens, and the adaptation and hardness coefficient between film layers are enhanced.

Description

Technical field [0001] The present invention belongs to the field of optical lens technology, specifically, relates to a hard-coated lens with strong adhesion. Background [0002] Whether it is an inorganic material or an organic material made of spectacle lenses, in daily use, due to the friction of dust and sand particles will cause the lens to wear, resulting in scratches on the surface of the lens, compared with glass sheets, organic materials made of lower hardness, more prone to scratches. The wear-resistant material is plated on the surface of the lens by soaking and vacuum coating. To improve the wear resistance of the lens, it is necessary to improve the hardness of the film layer and the lens connection layer and the density and wear resistance of the surface coating material, and increase the hydrophobicity of the film surface. [0003] At present, the commonly used method is to use the soaking method, the lens into the silicon element containing inorganic ultrafine ...
