Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lenses, and particularly to a waterproof and anti-radiation lens and a preparation method thereof. Background Art
[0002] Blue light refers to light with a wavelength in the range of 380 - 500 nm. Blue light is a type of visible light. It has a short wavelength and high energy and can directly penetrate the lens and reach the retina at the bottom of the eye. Among them, the short-wave blue light with a wavelength between 385 - 445 nm has the greatest harm to the retina. Moreover, there are many types of anti-blue light resin lenses on the market. The anti-blue light effects of resin lenses with different refractive indices are different, but the overall anti-blue light effect is relatively low, and they are just taking advantage of the market hot spot to win sales. In addition, with the gradual expansion of the resin glasses market, its resin lenses have also received more and more attention from consumers. Therefore, with the diversification of consumer requirements, all aspects of the performance and technology of resin lenses are constantly being improved and perfected.
[0003] Currently, mainly on the basis of hardened resin lenses, an anti-reflection film layer, a top waterproof layer, etc. are deposited through a vacuum coating method to achieve the effects of enhancing the transmittance and protecting the lens. The current optical lenses have poor anti-radiation performance. During long-term use by wearers, there is a risk of radiation damaging the eyes. At the same time, most current lenses are prone to water mist condensation. Although it is not harmful itself, it seriously affects daily life. The market often uses the method of hydrophilic coating to solve this problem, but the existing hydrophilic coatings cannot adhere tightly to the surface, leaving gaps between the coatings and the lenses, and the generated water droplets are easy to enter the glasses.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0024] The present invention uses resin glass as the substrate, coats an anti - radiation layer, and then modifies it to obtain a lens, making it have the functions of anti - radiation, anti - blue light, and waterproofing.
[0025] First, the present invention performs a hardening treatment to form a silicon layer on the surface of plexiglass; then a first deposition treatment is carried out. Microwave plasma discharge activates methane, and a chemical reaction occurs on the surface of the silicon layer to form carbon nanosheets, which are intertwined to form a carbon film; then a second deposition treatment is carried out. Nickel nitrate is vaporized and mixed with hydrogen and introduced. Since hydrogen can reduce nickel nitrate, nickel metal particles are formed and deposited on the surface of the carbon film. Then, ammonia gas is generated by the high temperature of a nitrogen-hydrogen mixed gas, effectively etching the nickel metal to form island-like particles. Then, using nickel as a catalyst, carbon nanotubes are grown vertically to the island-like structure through microwave plasma chemical vapor deposition, and are intertwined with each other to form a large number of voids, constituting impedance matching. And the carbon films are connected in series to form a large conductive network, which can convert electromagnetic radiation into current and dissipate it as heat, making the lens radiation-resistant. At the same time, it can prevent water vapor condensation, making the lens have an anti-fog effect; then a third deposition treatment is carried out. Iron-nickel alloy is electroplated using forward and reverse double pulses. By changing the direction, the surface protrusions are dissolved. At the same time, an external magnetic field is applied to make the surface pores disappear and refine the grains, forming a magnetic layer with uniform thickness and flatness. Then, non-magnetic titanium dioxide is sputtered and coated. While improving the anti-fog property of the lens, magnetic coupling is generated between magnetic particles to form a magnetic absorption network, promoting the magnetic loss of electromagnetic radiation and improving the anti-radiation ability of the lens; in addition, the existence of multiple interfaces and the resonance generated by magnetic particles act on electromagnetic waves together, making the lens have a strong electromagnetic radiation attenuation ability, accelerating the conversion of electromagnetic waves into heat energy, and improving the anti-radiation and anti-fog properties of the lens.
[0026] Secondly, titanium dioxide on the surface of the radiation-resistant layer is modified with hexamethylenediaminomethyltrimethoxysilane to introduce amino groups, which react with the chloride ions of 2-amino-3-chloro-6-bromobenzoic acid and are grafted onto the surface of titanium dioxide; then the cyano group of phenylacetonitrile and the amino group of dimethylaminopropylamine react with the bromide ion and carboxyl group of 2-amino-3-chloro-6-bromobenzoic acid respectively, and form a ring under the action of a catalyst to form an isatinone compound, which effectively absorbs blue light, thereby reducing the transmission of blue light and achieving a blue light filtering effect, making the lens have a blue light blocking effect; then (3S)-3-amino-N-cyclohexyl-2-oxohexanamide reacts with 2-amino-3-chloro-6-bromobenzoic acid to undergo an azo reaction to generate an azo group, which acts together with the isatinone compound to improve the blue light blocking property of the lens.

[0082]
[0083] From the comparison of the experimental data of the water mist dissipation time and the water mist condensation situation after irradiation between the examples and the comparative examples, it can be found that for the anti-radiation layer prepared by the present invention, by sequentially depositing a conductive layer, a magnetic layer, and a non-magnetic layer, the existence of multiple interfaces accelerates the conversion of electromagnetic waves into heat energy, improves the water mist resistance of the lens. At the same time, the non-magnetic layer uses titanium dioxide as the raw material, which can further improve the water mist resistance of the lens; from the comparison of the shielding rate experimental data between the examples and the comparative examples, it can be found that the present invention sequentially deposits a carbon film and vertically grown carbon nanotubes to form a conductive network in series, forming a conductive loss to improve the anti-radiation ability of the lens, then deposits a magnetic layer to form a magnetic loss, and then coats non-magnetic titanium dioxide to generate magnetic coupling between magnetic particles to form a magnetic absorption network, promoting the magnetic loss of electromagnetic radiation and improving the anti-radiation ability of the lens; in addition, the existence of multiple interfaces and the resonance generated by magnetic particles act together on electromagnetic waves, enabling the lens to have a strong electromagnetic radiation attenuation ability and improving the anti-radiation property of the lens; from the comparison of the transmittance experimental data between the examples and the comparative examples, after using the aminated modified anti-radiation layer, it is successively grafted with 2-amino-3-chloro-6-bromobenzoic acid, cinnamitrile, and dimethylaminopropylamine on the surface to form a ring to form an isoindolinone compound, which effectively absorbs blue light and makes the lens have an anti-blue light effect; then reacting with (3S)-3-amino-N-cyclohexyl-2-oxohexanamide to generate an azo group, which acts together to improve the anti-blue light property of the lens.
