Anti-fog film forming process of anti-fog goggle lens

Abstract

The invention relates to the field of lenses, in particular to an anti-fog film forming process of an anti-fog goggle lens. The anti-fog goggle lens comprises a goggle lens body and an anti-fog film plated on the inner side of the goggle lens body. The anti-fog film forming process comprises the following steps: (1) cleaning before film plating: before film plating, pre-cleaning the goggle lens body by adopting ion bombardment; (2) under a vacuum condition, carrying out multilayer vacuum plating on the cleaned goggle lens body by adopting high-hardness zirconium dioxide, and plating a layer ofhydrophilic coating by adopting the same plating method; and (3) baking the goggle lens body plated in the step (2), controlling the baking temperature to be 20-30 DEG C of the thermal deformation temperature of materials selected by the anti-fog film, and then melting and evaporating to obtain the anti-fog goggle lens with the anti-fog function. By the adoption of the plating process, the platedgoggle lens is high in abrasion resistance and has an anti-fog function.

Description

technical field [0001] The patent of the invention relates to the field of lenses, in particular to an anti-fog film forming process for anti-fog goggle lenses. Background technique [0002] Goggles are a kind of glasses that can avoid damage to eyes caused by radiation light by changing the transmitted light intensity and spectrum. In order to avoid fogging on the surface of the lens, it can be coated with anti-fog agent (such as surfactant) on the lens. The anti-fog agent is a super-hydrophilic nano-film, which changes the fog to a low freezing point after contacting it. mixture to prevent the fog from condensing into small water droplets and causing fogging on the surface of the lens; however, the anti-fog agent coated on the lens is very easy to peel off after a period of use or after cleaning and wiping the lens, and cannot be used for a long time Provide anti-fog effect, and when the user wears glasses, goggles or goggles and other items, the anti-fog agent on the len...
