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

The preparation method of high index of refraction optical resin material
One, technical field:
The present invention relates to a kind of manufacturing process of optical resin material, particularly a kind of preparation method of high index of refraction optical resin material.
Two, background technology:
In recent years, optical resin lens is with its fashionable domestic and international market of special advantage, and the high index of refraction optical resin lens more with its extra-thin fangle, comes out first in the eyeglass industry, the home market of selling well.Yet the resin lens of domestic present production all is a refractive index is 1.499 eyeglass, and still do not have enterprise and produce 1.60 high refractivity resin lens, refractive index is that 1.499 optical resin lens principal ingredient is diallyl two carbonic acid diethyl alcohol esters (being called for short ADC), the lens thickness made from ADC is thicker, and thermal resistance, visible light transmittance rate performance are compared very inferior with high refractivity resin lens.
Three, summary of the invention:
Technical matters to be solved by this invention is: the manufacturing process that the high index of refraction optical resin material of a kind of refractive index between 1.60~1.67 is provided.
The present invention is achieved like this: at ambient temperature, at first 1, after 3-two (acrylic acid glycerine ester group) glycerine and diallyl p phthalate, two compound of diallyl two carbonic acid binaryglycol esters stir, add a-methyl styrene, styrene successively, and tetrabromobisphenol A, continue to add 2-hydroxyl-3-phenoxy group propyl acrylate and isocyanate ester compound while stirring, stirred 2 hours; Add 0.1~0.3% ultraviolet light absorber and the blue toner of 0.2ppm~1ppm again.The weight proportion of described each compound is: isocyanate ester compound 10~12%, diallyl p phthalate 5%, tetrabromobisphenol A 10~15%, 1,3-two (acrylic acid glycerine ester group) glycerine 5%, 2-hydroxyl-3-phenoxy group propyl acrylate 25%, styrene 10~15%, a-methyl styrene 20~30%, diallyl two carbonic acid binaryglycol esters 3%.
Isocyanate ester compound has higher refractive index, halogen atom, the increase of oxygen atom, conjugated system increases in the molecule, the refractive index of the compound that the capital makes improves, the present invention utilizes isocyanates and the hydroxyl compound that contains halogen, compound fragrant hydrocarbon, and other polyol under certain conditions, formulated high dioptrics material, and this material is under the initiating agent effect, after solidifying by the program temperature control, get final product ultrathin high index of refraction optical resin lens, the inventive method synthesis technique is simple, the controllability of process and good reproducibility, the reaction conditions gentleness, pollution-free, cost is low, product surface hardness height.
Five, embodiment:
Stir at ambient temperature, at first 5% 1,3-two (acrylic acid glycerine ester group) glycerine and 5% diallyl p phthalate, after two compound of diallyl two carbonic acid binaryglycol esters of 3% are even, add 20~30% a-methyl styrene successively, 10~15% styrene and 10~15% tetrabromobisphenol A, because tetrabromobisphenol A is separated than indissoluble, under agitation, continue the 2-hydroxyl-3-phenoxy group propyl acrylate of adding 25% and 10~12% isocyanate ester compound, stirred 2 hours, as standard recipe, the blue toner that has added commercially available 0.3% ultraviolet light absorber and commercially available 0.2ppm~1ppm in mix monomer gets a pale blue transparency liquid, refractive index is 1.56, viscosity is 7mpa.s, moisture content 170ppm.Isocyanate ester compound can be to diisocyanate cpd, also can be a diisocyanate cpd or adjacent diisocyanate cpd, and its chemical structural formula is:
