Abstract

The invention relates to an UVLED-cured resin lens having a refractive index of 1.500, and a manufacturing method thereof. The resin formula of the lens comprises aliphatic acrylated polyurethane withthe functionality being 2-5 and the molecular weight being 1200-80000, cyclohexane dimethanol diacrylate, dihexanediol dimethacrylate, tripropylene glycol diacrylate and dipentaerythritol hexaacrylate which are compounded, and the lens also contains a photocatalyst, a toning dye and a light stabilizer. The lens resin and above additives are compounded, stirred and defoamed, and the obtained mixture is poured into a glass mold, and is cured by UVLED lights to obtain the resin lens having the refractive index of 1.500 + / - 0.004 and a visible transmittance of 90% or more. The resin formula is improved, and the curing molding manner of traditional resin lenses having a refractive index of 1.500 is changed, so photo-curing molding is realized, the efficiency in the molding process is greatly increased, and the energy consumption and the pollution are obviously reduced.

Description

technical field [0001] The invention relates to the technical field of resin lens production, in particular to a UVLED cured 1.500 refractive index resin lens and a manufacturing method thereof. Background technique [0002] At present, there are many kinds of optical resin materials. In 2005, there were more than 2,400 kinds of optical resin materials on the market. However, optical lenses have high requirements for materials, such as high light transmission performance, excellent anti-aging performance, high glass transition temperature and It is easy to dye the performance of lamps, so among many optical resin materials, there are very few that are actually used in the field of optical lenses. So far, polystyrene (PS), polycarbonate (PC), polymethyl methacrylate (PMMA), polydiallyl diglycol carbonate (CR-39), as traditional optical plastics, still occupy the Dominance of the Resin Market. [0003] CR39 (alias 1.500) is a commercial brand of optical resin, which was deve...
