Abstract

The invention discloses a self-cleaning optical resin lens and a preparation method therefor. The preparation method comprises the steps: putting nano-powder and nonionic surfactant into alkaline solution, moving a system into a polytetrafluoroethylene reaction still, and carrying out microwave hydrothermal reaction; slowly putting a resin substrate I into a nano solution, enabling the nano solution to be stationary for dipping, enabling the surface of the resin substrate I to grow a dense hydrophobic membrane, taking out the resin substrate I for drying, and obtaining a resin substrate II; carrying out the thermal curing processing of the resin substrate II, and obtaining a resin substrate III; carrying out the medium voltage radio-frequency sputtering of the resin substrate III, coating the surface of the resin substrate with an SiO2 film, and obtaining a resin substrate IV; carrying out the thermal curing processing of the resin substrate IV, and obtaining the self-cleaning optical resin lens. The self-cleaning optical resin lens is simple in technological method, is easy to operate, and can be produced in a large scale. The prepared self-cleaning optical resin lens has a super-hydrophobic surface, and achieves a good sterilizing effect.

Description

technical field [0001] The invention relates to the field of optical elements, in particular to a self-cleaning optical resin lens and a preparation method thereof. Background technique [0002] Resin lenses are favored by consumers for their advantages of light weight, unbreakable, and moderate price. However, because the surface of resin lenses is easy to absorb hydrophilic substances, it will cause foggy lenses, and the surface of the lens will attract air due to the adsorption of hydrophilic substances. Dust, thereby causing the lens surface of the spectacle lens to wear and tear, which seriously affects the clarity of the spectacle lens surface, and then causes the quality and service life of the spectacle lens to decline. [0003] The measures to improve this situation can start from improving the hydrophilicity of the surface of the resin lens. By enhancing the hydrophobicity of the surface of the spectacle lens, the contact between the spectacle lens surface and wat...
