Ultrahard waterproof membrane and processing technology of ultrahard waterproof membrane

Abstract

The invention relates to an ultrahard waterproof membrane and a processing technology of the ultrahard waterproof membrane. The ultrahard waterproof membrane sequentially comprises an optical glass lens (1), an antireflection membrane layer (2), a combination layer (3), a waterproof hardening layer (4) and an air layer (5) from bottom to top. The ultrahard waterproof membrane is characterized in that the antireflection membrane layer (2) is sequentially composed of first-layer high-medium refractive index membrane materials, second-layer medium-high refractive index membrane materials, third-layer high-medium refractive index membrane materials and fourth-layer medium-high refractive index membrane materials. According to the ultrahard waterproof membrane and the processing technology, mixed design of the multiple kinds of the membrane materials is adopted in membrane system design, the waterproof membrane materials and the antireflection membrane layer are well combined, and plated curves have the ultralow reflectivity; meanwhile, an electronic beam evaporation waterproof drug device is adopted in the evaporation technology, the membrane layer is firm and even, the produced ultrahard waterproof membrane has the waterproof, dustproof and hardening effect, and the low reflectivity is achieved.

Description

technical field [0001] The invention relates to the technical field of lens production, in particular to a superhard waterproof film and its processing technology. Background technique [0002] Compared with other ordinary lenses (digital lenses, mobile phone cameras, scanning lenses, etc.), sports optics lenses require a more stringent test for the reliability of the lens coating. Since the lens is installed on the telescope and gun sight lens, it is exposed to the wild for a long time. Exposure to the outside of the lens due to sun exposure and rain damages the lens. The hardened waterproof film is a special film layer with wear-resistant and self-cleaning functions, which can effectively improve the scratches on the lens surface of the vehicle lens and sports optical lens during the cleaning process, and can effectively reduce the adhesion of foreign matter to the lens. It is very useful to exclude raindrops especially in rainy days. With the development of the automoti...

Problems solved by technology

However, the immersion and ion polymerization methods require more process steps using separators, the process is complicated, and the quality is unstable; while the high vacuum coating method can directly follow the production of AR (anti-reflection) coating and use the same equipment, the product Stable quality, low cost, strong practicability
