Description

Technical Field

[0001] The present invention relates to the technical field of lenses, and specifically to a preparation method of a waterproof and anti-radiation lens. 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 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 in 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 closely adhere to the surface, leaving gaps between the coatings and the lenses, and the generated water droplets are easy to enter the glasses.

[0010] Further, the preparation method of the pretreated resin glass in step (1) is: Immerse the resin glass in an organosilicon hardening solution 5 - 10 times the mass of the resin glass, let stand for 3 - 7 min, and then cure at 80 - 90 °C for 30 - 46 min.

[0014] Further, the dual-pulse electroplating parameters in step (3) are: pulse frequency is 2 kHz, forward pulse current density is 5-9 A / dm 2 , duty cycle is 0.30-0.42, reverse pulse current density is 0.9-1.5 A / dm 2 , duty cycle is 0.17-0.32.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention uses resin glass as a substrate, coats a radiation protection layer, and then obtains a lens through modification, so that it has the functions of radiation protection, blue light protection, and anti-fog.

[0016] 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 radiation protection ability of the lens; in addition, the existence of multiple interfaces and the resonance generated by magnetic particles act together on electromagnetic waves, making the lens have a strong electromagnetic radiation attenuation ability, accelerating the conversion of electromagnetic waves into heat energy, and improving the radiation protection and anti-fog properties of the lens.

[0017] Secondly, titanium dioxide on the surface of the radiation protection 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, achieving the effect of filtering blue light and making the lens have an anti-blue light 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 anti-blue light property of the lens.

At the same time, the non-magnetic layer uses titanium dioxide as a raw material, which can further improve the waterproof mist property 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 and improving the anti-radiation ability of the lens. Then, a magnetic layer is deposited to form a magnetic loss. By coating with non-magnetic titanium dioxide, magnetic coupling is generated between the 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 the magnetic particles act together on the 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 an aminated modified anti-radiation layer, 2-amino-3-chloro-6-bromobenzoic acid, cinnamitrile, and dimethylaminopropylamine are sequentially grafted onto the surface to form a ring to form an isoindolinone compound, effectively absorbing blue light and making 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.
