Embodiment

[0033] Take out a barrel of 20kg from the cold storage, and the main components are 2-hydroxy-3-phenoxypropyl acrylate, α-methylstyrene, diallyl terephthalate and isocyanate high-refractive-index optical resin material for production The basic raw material of high refraction optical resin lens, the preparation method of this raw material is as follows: at room temperature, first mix 5% of 1,3-bis(acrylic acid glyceryl) glycerin and 5% of diallyl terephthalate , 3% Dipropylene Dicarbonate Diethylene Glycol After the two compounds are mixed and stirred evenly, add 27% a-methylstyrene, 13% styrene and 12% tetrabromobisphenol A bis( 2-hydroxyethyl) ether, while stirring, continue to add 25% of 2-hydroxy-3-phenoxypropyl acrylate and 10% of m-xylylene diisocyanate, stir for 2 hours; add 0.3% of ultraviolet light Absorbent and 0.2ppm ~ 1ppm blue agent. Stir in the dissolving tank, raise the temperature to 40°C, keep it warm for 10 minutes, then cool it down to 30°C with cooling wate...

Abstract

The manufacture process of superthin high-refractivity optical resin lens includes the following steps: making mold, reinforcing treatment and closing mold with tape machine; weighing chemical monomer and initiator, mixing and vacuum deairing; depositing the mixture in the mold, curing to form, demolding and cleaning. The present invention features the chemical monomer with one kind of alkenyl radical containing organic compound additive, the initiator being tert-butyl peroxide, the ratio among the chemical monomer, the additive and the initiator of 100 to 0.1-0.3 to 0.7-0.9, computerized temperature control during the polymerization, and the secondary curing of lens after demolding and cleaning. The present invention eliminates the lens profile variation caused by the polymerization and raises the optical precision of the lens.

Description

1. Technical field: [0001] The invention relates to a manufacturing process of an optical resin lens, in particular to a manufacturing process of an ultra-thin high-refractive index optical resin lens. 2. Background technology: [0002] High-refractive optical resin lens is a newly developed high-grade resin lens in the world in recent years. It is currently the best material for making spectacle lenses among polymer materials. It is light in texture, dense in molecular structure, good in light transmission, thin in lens, strong in hardness, and has unique advantages such as effectively preventing ultraviolet rays. Ultra-thin The production process of high-refractive optical resin lenses contains high technical content. It is a high-tech internationally. At present, all such high-end lenses in China rely on imports. The optical resin lenses currently produced in China are all lenses with a refractive index of 1.499. The thickness of the lenses is relatively thick, and the v...
