| titleOfInvention | A kind of anti-infrared spectacle lens and preparation method thereof |
| abstract | The invention relates to an anti-infrared spectacle lens and a preparation method thereof, belonging to the technical field of optical lens preparation. In the present invention, the corn starch with spherical structure is used as a template, urea is used as an organic phase dispersant, ferrous chloride is used as a raw material, and ammonia water is used as a precipitant, and the ferrous salt nanoparticles are prepared by a solution method, and the surface of the ferrous salt is modified. Active agent, the surfactant-modified nanoparticles are wrapped with polymer resin by soap-free emulsion polymerization to form a core-shell structure, and this core-shell structure is added as a red light (infrared) absorber to conventional lens monomers , processed into anti-red light lenses. The addition of the core-shell type ferrous salt nanoparticles of the present invention significantly improves the infrared resistance performance of the lens, and has little influence on the mechanical strength of the original lens, and has broad application prospects. |
