Embodiment 1

[0032] Add 0.25 moles of epichlorohydrin and 0.1 moles of dimercapto diphenyl sulfide into a three-necked flask equipped with a stirring device, a thermometer and a reflux condenser, stir and dissolve in a water bath; add 0.001 moles of quaternary ammonium salt as a catalyst ;React for 2 hours at a water bath temperature of 70°C; then raise the temperature, and recover most of the unreacted epichlorohydrin by distillation at a temperature lower than 120°C; then keep the reaction temperature at 70°C, and within 2~2.5 hours Add solid sodium hydroxide four times, adding once every 0.5 hours, wherein the total amount of sodium hydroxide added is 0.2 moles; then keep it warm for 0.5 to 1 hour at a temperature of 70°C to generate a reaction product. Add 0.2-2 moles of methyl isobutyl ketone into the reaction product, then stop stirring and discharge. Put the material in a separatory funnel, add 10 moles of distilled water, oscillate to form an organic layer and a water layer, separa...

Abstract

The invention relates to an optical epoxy resin and a synthesis method thereof. The optical epoxy resin is a thiobisbenzenethio-diphenol diglycidyl ether copolymer. The invention also provides a synthesis method of the optical epoxy resin. The optical epoxy resin and the synthesis method thereof have the advantages of easiness in popularization and application.

Description

technical field [0001] The invention relates to an epoxy resin and a synthesis method thereof, in particular to an optical epoxy resin and a synthesis method thereof. Background technique [0002] Epoxy resin has the characteristics of easy curing, adjustable curing conditions and good transparency, so it is widely used in the field of optical resins, such as optical devices, optical packaging and optical adhesives. However, the refractive index of common epoxy resin is relatively low, and its refractive index is about 1.57, which cannot meet the increasingly higher requirements of optical materials. [0003] In order to increase the refractive index of the optical epoxy resin without reducing the light transmittance of the material, in the prior art there is a method of compounding inorganic nanomaterials to adjust the optical epoxy resin. These inorganic nanomaterials are, for example, nano-titanium dioxide, nano-zinc oxide, nano-zinc sulfide, and the like. However, the ...
