月桂酸逆酯甲基锡热稳定剂产品的研发

Research and Development of the Mercaptoethyl Laurate Methyltin Heat Stabilizers

介绍了月桂酸逆酯甲基锡热稳定剂的工艺原理、合成方法、加工性能及应用领域。考察了反应温度、酸度、时间、物料配比等参数对收率的影响。然后,使用开放式炼塑机及转矩流变仪测试发现,月桂酸逆酯甲基锡具有热稳定性能优异、润滑性好、透明度高等特点,能够满足PVC管材、型材、异型材、片材等制品的加工要求。

The process principle,synthesis methods,process performance and application field of the mercaptoethyl laurate methyltin heat stabilizer were first introduced.Then,the effects of reaction temperature,acidity,time and material ratio on the yield were discussed.Finally,by use of an open plasticator and a torque rheometer,the mercaptoethyl laurate methyltin possess excellent thermal stability,good rheological property,high transparency and other characteristics were discovered suitable for PVC pipes,profiles,irregular profiles,sheets and other products processing.
