Production process of self-cleaning optical lens glass

Abstract

The invention relates to a production process of self-cleaning optical lens glass. The process is characterized by including the following steps: material compounding: by weight, compounding 130-140 parts of silica sand, 50-58 parts of sodium carbonate, 40-50 parts of quartz stone, 1-5 parts of alumina powder, 0.5-0.8 part of boron oxide, 1-2 parts of amphibole, 0.2-0.3 part of cerium oxide, and 0.4-0.5 part of antimony trioxide; melting; molding: performing calendaring molding at 800-1000DEG C; heat treatment, grinding and polishing; spraying: spraying a layer of self-cleaning coating on the glass surface, wherein the self-cleaning coating comprises the following components: 10-20 parts of shell powder, 4-6 parts of a binder, 1-2 parts of chlorite schist powder, 1-3 parts of antimony oxide, 4-6 parts of octadecyl silane bonded silica gel, and 3-6 parts of peach gum. The photovoltaic glass provided by the invention has self-cleaning function, dust does not adhere to the glass surface easily, and the photovoltaic glass has high strength, high compactness, and good optical properties.

Description

[0001] Technical field: [0002] The invention relates to the technical field of optical glass production, in particular to a production process for self-cleaning optical lens glass. [0003] Background technique: [0004] The optical lens is an essential part of the machine vision system, which directly affects the quality of the image and affects the realization and effect of the algorithm. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and telephoto lenses in terms of focal length; wide-angle, standard, and telephoto lenses in terms of field of view; fixed-aperture fixed-focus lenses and manual aperture fixed-focus lenses in terms of structure. Auto-iris fixed-focus lenses, manual zoom lenses, auto-zoom lenses, auto-iris electric zoom lenses, electric three-variable (aperture, focal length, and focus) lenses, etc. The lens material of the optical lens is generally resin material or glass material. Both materials have their own advantages and dis...

Problems solved by technology

The lens material of the optical lens is generally resin material or glass material. Both materials have their own advantages and disadvantages. As an optical lens made of glass, it is easy to break, but has good optical performance. However, due to the different production processes, for some
