Anti-fog lens with dopamine as surface bonding layer, and technological process thereof

Abstract

The invention provides an anti-fog lens with dopamine as a surface bonding layer, and a technological process thereof. The anti-fog lens is composed of a substrate (1), a stiffened film layer (2), an anti-reflecting film layer (3), a waterproof film layer (4), the dopamine bonding layer (5) and an anti-fog film layer (6). The anti-fog lens is characterized in that the dopamine bonding layer (5) is adhered on the surface of the waterproof film layer (4) through dipping; and the hydrophilic anti-fog film layer (6) is bonded with the surface of the dopamine bonding layer (5) through dipping. According to the anti-fog lens, an anti-fog paint is combined with the surface of a resin lens for realizing no easy falling, thereby forming the firm anti-fog film layer after heat-curing, and realizing long-term anti-fog function of eyeglasses. The anti-fog lens has advantages of high novelty, simple process, high adhesion firmness and high practicability.

Description

technical field [0001] The invention relates to the technical field of production and application of anti-fog spectacle lenses, in particular to an anti-fog lens made by using dopamine as an adhesive layer on the surface of a resin lens and a process method thereof. Background technique [0002] Consumers who wear vision correction glasses now generally use resin lenses made of surface hard coating technology. In order to improve the surface hardness of this kind of lenses, a layer of silicon dioxide and hard coating layer is usually coated on the surface of the lens by dip coating process. , dried in an oven at 120°C, and then sent to a vacuum evaporation film machine to evaporate a layer of anti-reflection film such as zirconia with a thickness of tens of nanometers under vacuum conditions to improve the light transmittance of the lens, and finally in the anti-reflection film A layer of hydrophobic film layer containing fluoride is vapor deposited on the film layer, which ...
