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 ...

[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 increases the surface tension of the lens to about 150° and presents a strong hydrophobic state. The advantage of this is that it is waterproof. It will adhere to the surface of the lens to maintain the clarity of vision of the glasses, but it cannot achieve anti-fog function while being strongly hydrophobic. The surface of the lens can no longer be combined with other hydrophilic coatings to form a hydrophilic anti-fog film layer, thus As a result, the resin lenses being produced by the factory and the existing consumers who already wear glasses cannot add anti-fog function to the glasses for convenience, and the anti-fog function of glasses is what many consumers who wear glasses for vision correction are very concerned about and need. of
