Optical glass surface evaporation process

Abstract

The invention discloses an optical glass surface evaporation process which comprises the following steps: after cleaning the surface of optical glass, carrying out plasma treatment on the surface of the optical glass to enable the water drop angle value of the surface of the optical glass to be lower than 15 degrees, then evaporating an OC-3001 material on the surface of the optical glass, furthercarrying out plasma treatment, and continuing to evaporate a color film or an antireflection film. The cost of the process is only lower than half of that of a traditional process, the product is manufactured at a time through evaporation, the yield is greatly improved, working procedures are reduced, and the productivity is increased at the same time.

Description

Background technique [0001] After the existing optical glass is made of color film or anti-reflection film, the toughness of the material decreases significantly, resulting in a decrease in user comfort. Therefore, before the material is made into a color or an anti-reflection film, a layer of micron-sized OC0 material will be sprayed in advance, and the main component of the material is polyester resin. OC0 is a liquid spraying resin material. When the glass is magnified and observed under a microscope, it can be seen that there are fine internal cracks (generated in the process of tempering the glass). After spraying the OCO material, the OC0 material can play a filling role and has a large Adsorption and ultra-low water drop angle, spraying OC0 material and then making a coating layer can greatly improve the toughness of the material. [0002] The process of spraying OCO material mainly includes: product surface pure water cleaning + plasma cleaning + spraying OC0 material...

AI Technical Summary

Problems solved by technology

[0004] 1. It requires two different processes (spraying + evaporation) to be produced together. The production process is complicated, requiring a large amount of personnel, equipment, and capital costs, and the production efficiency is low;

[0005] 2. There are many production processes, and the production yield is low, generally about 75%;

[0006] 3. The OC0 materials used are expensive, and special personnel are needed to follow up the production. About 3 people are needed in the spraying process, and a special operator is required to operate;
