Problems solved by technology

There are optical resin lenses with a refractive index of 1.56 made of chemical monomers whose main components are phenylacrylates and other components, but their thickness is relatively thick, and their thermal resistance and visible light transmittance are relatively low. Poor, so it is necessary to have an optical resin monomer material for making high refractive index resin lenses

Abstract

The invention provides an optical resin monomer material. The optical resin monomer material consists of the following components in percentage by weight: 10 to 20 percent of 1,2-bi(2- sulfhydry ethylthio)-3-sulfhydryl propane, 15 to 25 percent of isocyanate compound, 5 to 10 percent of alpha-methyl methacrylate, 10 to 15 percent of tetrabromo bisphenol A, 20 to 30 percent of 2-hydroxyl-3-phenoxycrylic acid propyl ester, and 10 to 20 percent of styrene compound. The optical resin monomer material can be used for producing an ultrathin type high-refractive index optical resin lens of which therefractive index is 1.60 by the conventional process. Compared with the prior art, the invention provides the optical resin monomer material, which can be used for producing the high-refractive indexoptical resin lens and ensure the produced lens is thinner and has high thermal resistance and visible-light transmittance.

Description

Technical field [0001] The invention relates to an optical resin monomer material, in particular to a preparation technology of a high refractive index optical resin material. Background technique [0002] In recent years, optical resin lenses have sprung up in the domestic and foreign eyewear markets. In particular, high refractive index optical resin lenses have unique advantages such as light weight, high strength, resistance to breakage, high light transmittance, UV protection, and ultra-thin type. It is very popular among people with low vision. Generally, in the lens industry, those with a refractive index above 1.60 are regarded as high refractive index, those with a refractive index above 1.56 are regarded as medium refractive index, and those with a refractive index below 1.56 are regarded as low refractive index. There are optical resin lenses with a refractive index of 1.56, which are made of chemical monomers composed of phenyl acrylates and other components, but the...
