ANTI-BLUE LIGHT OPTICAL RESIN LENS AND PREPARATION METHOD THEREFOR

摘要

The present invention disclose a blue-light-proof optical resin lens, comprising resin monomers, a blue light absorber and a polymerization initiator; the mass ratio of the resin monomers to the blue light absorber to the polymerization initiator is 100:0.01-2.00:1.00-4.00; the resin monomers are the mixture of allyl diglycol carbonate (ADC) and polymers thereof; the blue light absorber is a benzophenone type ultraviolet light absorber and/or indole type blue light absorber; the polymerization initiator is selected from one or two of tert-butyl peroxy-2-ethylhexyl carbonate, tert-amyl peroxy-2-ethylhexyl carbonate and 1,1-di-(tert-butylperoxy)-3,3,5-trimethylcyclohexane. A preparation method includes the following steps: weighing the resin monomers, the blue light absorber and the polymerization initiator by ratio, sealing the mixture at room temperature, uniformly stirring the mixture at vacuum, filtering the stirred mixture with a filter core, and then vacuuming; (2) immediate pouring, molding by thermocuring; (3) mold opening, washing the obtained product; (4) annealing the obtained product, and inspecting the product. The blue-light-proof optical resin lens prepared by the method has a blue light absorbency (380-500nm) of 15%-40%.
