Problems solved by technology

However, optical resin materials widely used in the market, such as polymethyl methacrylate (PMMA), CR-39, etc., have a low refractive index (nD<1.50), and the traditional optical resin with the highest refractive index PS can only reach nD=1.590, and the overall performance is not very ideal, which limits the application range of the material

Abstract

The invention discloses a macromolecular resin lens with high refractive indexes. The macromolecular resin lens with high refractive indexes is prepared from the following raw materials in percentageby weight: 15-25% of dibutyl phthalate, 5-20% of allyl alcohol, 30-50% of isocyanate, 0.002-0.05% of dibutyltin dichloride, 0.06-0.1% of a photo-curing initiator, and the balance of methyl styrene. The invention further provides a preparation method of the macromolecular resin lens with high refractive indexes. The macromolecular resin lens with high refractive indexes and the preparation method thereof are capable of reducing weight of lens and improving refractive indexes of resin.

Description

technical field [0001] The invention relates to a resin lens, in particular to a high-refractive-index polymer resin lens and a preparation method thereof. Background technique [0002] In addition to inorganic glass, the research and development of using synthetic resin with excellent optical properties as lens materials is constantly developing, and there is a tendency to gradually replace traditional lens materials. Compared with inorganic glass lenses, resin lenses are characterized by light weight, high transparency, large lens size, impact resistance, easy processing and molding, and dyeing. Resin sheets are in a priority position in the eyewear market competition. According to reports, in 1988, optical resin lenses accounted for 65% in the United States and about 55% in Japan. About 85% to 90% of the 32 million people who wear glasses in Japan recently use resin lenses. Synthetic resin optical lenses were first made of polyallyl diglycol carbonate developed by the ...
