Abstract

The invention relates to a preparation method of a photochromic lens capable of blocking ultraviolet rays, a product and application thereof, wherein the method comprises the step of preparing a photochromic lens with a general formula MaObXcWherein M, O and X and a, b and c are as defined herein, and preparing a photochromic lens by mixing the photochromic nanomaterial with an optical resin material for preparing a lens and then molding the mixture, or preparing a photochromic lens by coating the surface of the molded lens with the photochromic nanomaterial and then forming a protective layer. The photochromic lens prepared by the invention can block more than 80% of ultraviolet rays, and can be changed into transparent dark color particularly under the irradiation of strong light, so that the transmittance is reduced; the colorless and transparent state can be recovered when no strong light irradiates. The method has the characteristics of simple process flow, low cost, high yield, suitability for industrial production and the like, and has better practical prospect.

Description

Preparation method of photochromic lens capable of blocking ultraviolet rays, product and application thereof
Technical Field
The invention relates to the field of intelligent color-changing materials and articles, in particular to a preparation method of a photochromic lens capable of blocking ultraviolet rays, the photochromic lens and application thereof.
Background
Photochromic refers to that some compound materials are subjected to a certain chemical reaction under the irradiation of light with a certain wavelength and intensity, so that the structure of the compound is changed, the color of the compound is changed, and the color is recovered or is changed newly after the irradiation of the light with another wavelength and intensity is removed. Since the last 50 s, Hirshberg et al reported the possibility of applying photochromic materials to optical recording and storage, the properties and applications of various novel photochromic materials have been systematically studied and widely applied in the fields of building window glass, photochromic spectacle lenses, vehicle window glass, information storage materials, decorative materials, photosensitive materials, and the like.
The research on photochromic materials has mainly focused on two broad categories, namely organic photochromic materials and inorganic photochromic materials. However, the organic photochromic material has the problems of poor thermal stability, easy aging, weak weather resistance and the like, and practical application thereof is limited. Inorganic photochromic materials are receiving attention for their many superior characteristics over organic photochromic materials. To date, the research on inorganic photochromic materials has focused on transition element oxides (e.g., M)oO3、TiO2、Nb2O5、WO3、Ta2OsBeO, etc.), metal halides (e.g., CuCl2、CdCl2AgX, etc.), polyoxometallates, rare earth complexes, etc. Although some material systems have become relatively mature, problems such as high raw material costs and complex processing techniques exist, limiting their large-scale commercial application. Meanwhile, many existing photochromic materials can only reduce the transmittance of light, but cannot block ultraviolet rays in sunlight which have the greatest influence on human bodies.
Photochromic eyewear was the first successful commercial product developed by scientists based on photochromic materials, starting in the 60's 20 th century, two materials scientists, amistod and Stooky, in the united states first discovered reversible photochromic properties of silver halide (AgX) containing glasses; the american corning company developed color changing eyewear by incorporating silver halide and a photosensitizer into glass to make lenses.
The literature (journal of scientific and technological economy, 2016 (7): 105-; however, the traditional silver halide photochromic glasses have high cost and large processing difficulty, and cannot meet the requirement of industrial production on production cost. With the continuous emergence of resin materials, lenses based on silver halide glass gradually come out of the mainstream market, and are replaced with photochromic lenses based on resin lenses and novel photochromic materials.
In conclusion, with the continuous improvement of the life quality of people, the demand of people on the color-changing lens is continuously increased, and the application range of the color-changing lens is also continuously expanded. The existing photochromic lens has the defects of high raw material cost, complex process technology and the like which can not meet the requirement of industrial production economy, and the development of the photochromic lens on commercial application is hindered. Therefore, there is an urgent need to develop a photochromic lens that has a simple process technology, low cost of raw materials, strong weatherability, and can block ultraviolet rays and can be commercially applied on a large scale.
Disclosure of Invention

mixing an anion source compound containing X with a second solvent to obtain a second solution;
injecting the second solution into the hot first solution to react to obtain a reaction mixture; and
cooling, separating, washing and/or drying the reaction mixture to obtain the photochromic nanometer material,
wherein M represents one or more selected from tin, indium, antimony and bismuth, or a combination thereof with one or more selected from titanium, barium, nickel, vanadium, zinc and copper; o represents an oxygen atom; x represents a group selected from the group consisting ofaObXcIn (M)aOb) One or more of tungstate radical unit, molybdate radical unit, vanadate radical unit, fluorine, chlorine, bromine and iodine capable of forming compound, or combination thereof with one or more selected from sulfur, carbon, phosphorus and boron, and in the general formula MaObXcWherein the molar ratio of the components a, b and c is (1-50) to 1;
