Problems solved by technology

In addition, since the main material of the optical film is an inorganic material, and the substrate of a polymer resin lens is an organic material, the difference in physical and chemical properties of the two leads to a high stress on the lens after coating, which in turn leads to poor temperature resistance and durability. In particular, the film layer with low-reflection anti-infrared function is generally thicker, and its impact on the stress of the coated lens is particularly significant, which affects its normal use.

Abstract

The invention provides a low-reflection anti-infrared high-temperature-resistant resin lens and a preparation method thereof. The low-reflection anti-infrared high-temperature-resistant resin lens comprises a resin lens substrate, a hardening layer, a low-reflection anti-infrared film layer and a waterproof layer; wherein the substrate, the hardening layer and the low-reflection anti-infrared layer are sequentially arranged, the hardening layer is located on the surface of the resin lens substrate, and the low-reflection anti-infrared layer is located on the surface of the hardening layer; andthe low-reflection anti-infrared layer is composed of a high-refractive-index material titanium-niobium composite oxide and a low-refractive-index material silicon-aluminum composite oxide. By adjusting the structure of the low-reflection anti-infrared film layer and a proper process, the resin lens with a good visual effect is obtained while low reflection is met, the high-temperature resistanceand the environmental resistance of the resin lens are greatly improved, and the resin lens has a good market application prospect.

Description

technical field [0001] The invention relates to the technical field of resin lens preparation, in particular to a low-reflection anti-infrared and high temperature resistant resin lens and a preparation method thereof. Background technique [0002] In recent years, the demand for optical resin lenses in the domestic and foreign glasses markets has been increasing. Compared with glass lenses, resin lenses have the advantages of light weight, good dyeing performance, and easy processing. Medium and high refractive index optical resin lenses are more transparent High efficiency, UV protection, ultra-thin and other unique advantages are favored by users. [0003] Generally, in the lens industry, a lens with a refractive index above 1.60 is a high refractive index, a refractive index of 1.56 is a medium refractive index, and a refractive index below 1.56 is a low refractive index. In order to meet the requirements of the optical properties of resin lenses, the surface of resin l...
