橡胶硫化促进剂二乙基二硫代氨基甲酸锌制备及光谱分析

Preparation of Rubber Accelerator Zinc Diethyldithiocarbamate and Its Spectral Analysis

合成二乙基二硫代氨基甲酸锌(EZ),采用溶剂蒸发法培养单晶配合物EZ,通过XRD单晶衍射仪、FTIR、TG-DSC对其进行检测和表征,揭示了单晶配合物EZ的微观结构和内在规律性。EZ高度有序化定向排列结构,决定其高效的橡胶硫化促进性能。TG-DSC检测结果表明,配合物EZ中蕴含少许的二硫化碳,FTIR揭示了EZ内部的化学键键型,与单晶衍射仪从不同侧面检测的结果一致,为确定EZ的分子结构提供了实验依据。EZ的分解温度偏高,为采用硫化仪研究EZ的橡胶硫化性能提供参考。本研究为企业选定工作标准品,对EZ工业化生产进行跟踪检测,评判EZ的产品性能指标,填报立项EZ化工行业标准的申报,撰写标准草案,提供基础实验数据。

In the study,rubber accelerator Zinc diethyldithiocarbamate（EZ）was synthesized firstly.Complex EZ of single crystal was cultivated by solvent evaporation method.EZ was detected and characterized by XRD single crystal diffraction,FTIR and TG-DSC.The micro-structure and intrinsic regularity were revealed.Its highly efficient performance of rubber vulcanization promotion was decided due to its orientation structure？and high order.The result of TG-DSC showed that complex EZ was possessed with a little CS2.The chemical bond types in EZ were revealed by FTIR,the same as single crystal？diffraction testing by different way.The decomposition temperature of EZ was very high.It could provided reference with research on rubber vulcanizing properties by EZ on rubber vulcanizing machine.This study can help the enterprises to designate the working standard tracing detection of EZ industrialized production.Performance index of EZ was judged.The project of EZ industry standard can be declared by the enterprises,written a draft standard on the basis experimental data.
