High-contrast high-definition lens and preparation method thereof

Abstract

The invention relates to the technical field of optical lenses, and especially relates to a high-contrast high-definition lens and a preparation method thereof. The lens comprises cured film layer slurry, a mixed solution 1 and a substrate, and the mixed solution 1 and the cured film layer slurry jointly comprise, by weight, 40-80 parts of bisphenol A epoxy acrylic resin, 10-60 parts of dioctyl adipate, 10-30 parts of vinyl trimethoxy silane, 0.3-0.5 part of a modified additive, 3-10 parts of praseodymium oxide, 3-10 parts of neodymium oxide, 2-10 parts of an azo nickel metal compound, 10-20 parts of a dispersing agent, 5-15 parts of a surfactant, 0.1-0.5 part of a defoaming agent, 20-30 parts of a wetting agent, 5-8 parts of a humectant and 15-40 parts of acrylic resin. According to the high-contrast and high-definition lens and the preparation method thereof provided by the invention, the problems of poor dispersibility and compatibility of a photosensitive material in an acrylic acid material are solved, and the color uniformity and definition of the lens are improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a high-contrast high-definition lens and a preparation method thereof. Background technique [0002] Most of the current prior art materials are injection-molded lenses such as polycarbonate and nylon, and their optical properties are not as high as those of polyurethane and acrylic esters, and their Abbe coefficients are relatively low. And because the base has a certain color depth, when making a lens with a certain diopter, the edge part is thicker and the center is thinner. Due to the difference in thickness, the center of the lens looks light and the edge is too dark, which seriously affects wearing. Feel, and look good. However, materials such as azo-nickel metal compounds have poor dispersion performance in polyurethane or acrylic materials, and are easy to agglomerate, resulting in uneven color. It is difficult to prepare polyurethane and acrylic lenses with high ...
