本发明涉及一种光学材料用聚硫氨酯树脂组合物及其制造方法，通过将至少包含有机锆铋合金复合物、异氰酸酯类化合物、硫醇类化合物的组合物加热固化而得到。本发明涉及的光学材料用聚硫氨酯树脂组合物不含有机锡化合物，因长适用期，高选择性，其在不损失树脂光学、机械和耐热等性能下，可提高制品合格率。本发明涉及的聚硫氨酯树脂特别适用于透镜、棱镜等制品。

The invention relates to a polythionocarbamate resin composition for an optical material and a preparation method thereof. A composition at least containing an organic zirconium-bismuth alloy compound, an isocyanate compound and a thiol compound is heated to cure so that the polythionocarbamate resin composition is formed. The polythionocarbamate resin composition for an optical material does notcontain an organic tin compound, has a long life and high selectivity, retains resin optical, mechanical and heat-resistant properties of the resin and has a high qualification rate. The polythionocarbamate resin is particularly suitable for products such as lenses and prisms.
