Embodiment 1

[0013] 10% m-xylylene diisocyanate, 5% diallyl terephthalate, 12% tetrabromobisphenol A bis(2-hydroxyethyl) ether, 1,3-di(glycerylacrylate) glycerin 5%, 2-hydroxy-3-phenoxy propyl acrylate 25%, styrene 13%, a-methyl styrene 27%, diethylene glycol dipropylene dicarbonate 3%, dubbed mono The properties of the body are: the specific gravity is 1.07, the refractive index is 1.563, the viscosity is 70mpa.s, and the water content is 170ppm. After adding 0.5-1% initiator, it is cured and formed into an ultra-thin high-refractive index resin lens. The refractive index is 1.595. A multiple of 32.

Abstract

The preparation process of high reflectivity optical resin includes the following steps: mixing 1, 3-di(glyceryl acrylate) glycerin, diallyl terephthalate and dipropenyl styrene glycol bicarbonate via stirring under room temperature; adding a-methyl styrene, styrene and bisphenol A tetrabromide successively; adding 2-hydroxy-3-phenoxy propyl acrylate and isocyanate compound while stirring for 2 hr; and adding ultraviolet absorbing agent in 0.3 % and blue pigment in 0.2-1 ppm. The said preparation process is simple, and has good controllability and repeatability, mild reaction condition, no pollution, low cost and high product surface hardness.

Description

1. Technical field: [0001] The invention relates to a manufacturing process of an optical resin material, in particular to a preparation method of a high refractive index optical resin material. 2. Background technology: [0002] In recent years, optical resin lenses have become popular in domestic and foreign markets due to their special advantages, and high-refractive index optical resin lenses are even more popular in the domestic market because of their ultra-thin new styles. However, the resin lenses currently produced in China are all lenses with a refractive index of 1.499, and there is no company that produces 1.60 high refractive index resin lenses. ), the thickness of the lens made of ADC is relatively thick, and its thermal resistance and visible light transmittance are inferior to those of high refractive index resin lenses. 3. Contents of the invention: [0003] The technical problem to be solved by the present invention is to provide a manufacturing process ...
