Abstract

The invention relates to a high-strength anti-blue-ray and anti-ultraviolet PC lens and a preparation method thereof. The high-strength anti-blue-ray and anti-ultraviolet PC lens adopts optical-gradehigh-strength PC resin as a base material, the lens has good mechanical properties, good impact resistance and high strength, and through hardening of fluorine-containing hardening liquid, the problemof poor wear resistance of the PC resin is solved. A prepared high-temperature-resistant, anti-blue-light and anti-ultraviolet-light absorbent can be well compatible with PC resin, and the lens can be processed through an injection molding process, so that the preparation process is simple, the product stability is good, and the cost is low. The transmittance of the lens is improved through coating, and the color difference problem of the anti-blue-ray lens is solved as much as possible. The PC lens has good visibility and excellent harmful blue light and ultraviolet light protection performance, beneficial blue light is reserved as much as possible, eyes can be prevented from being stimulated by harmful blue light and ultraviolet light under different light conditions, and eyeballs are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of preparation of optical resin lenses, in particular to a method for preparing high-strength anti-blue light and anti-ultraviolet PC lenses. Background technique [0002] Polycarbonate resin, also known as PC resin, is a thermoplastic material mainly used in the field of optical resins. It softens after heating and is suitable for thermoplastic and injection molding. Polycarbonate (PC) material has excellent mechanical properties, high plasticity, easy molding, excellent light transmittance, high impact strength 50 times higher than glass, good dimensional stability and firmness. At the same time, PC material also has good heat resistance, even if it is exposed to high temperature environment for a long time, its optical properties will not be changed. And the PC material itself has better absorption of ultraviolet light below 380nm, which is beneficial to the ultraviolet protection performance of the lens. [0003...
