| titleOfInvention | Sulfur-containing optical resin material with high transmittance and high refractive index and preparation method thereof |
| abstract | A sulfur-containing optical resin material with high transmittance and high refractive index and a preparation method thereof are disclosed, the preparation method comprises the following steps: reacting 1,3, 5-tribromomethylbenzene with thiourea, preparing isothiourea salt by using ethanol-n-butyl acetate as a solvent, and then adding sodium hydroxide for hydrolysis; extracting with chloroform, and adsorbing impurities with attapulgite to obtain high-purity colorless 1,3, 5-trimercaptomethylbenzene; 1,3, 5-trithiol methyl benzene and isocyanate are subjected to polymerization reaction to prepare the optical resin material with high refractive index and high light transmittance. The 1,3, 5-trimercaptomethylbenzene compound prepared by the method has high purity, and the monomer and resin materials have the advantages of high refractive index, high transmittance and the like, wherein the light transmittance of the 1,3, 5-trimercaptomethylbenzene is more than or equal to 89%, the refractive index is more than or equal to 1.65, and the yellow index is less than or equal to 1; the light transmittance of the resin material is more than or equal to 90 percent, the refractive index is more than or equal to 1.66, and the yellow index is less than or equal to 1.50. |
