【摘要】 采用混合溶剂法和相转移催化剂合成了酯基锡(丁酯)热稳定剂,用红外光谱仪和核磁共振仪对其结构进行了表征,用流变仪和测色配色仪对其进行了热稳定性测试。结果表明,酯基锡(丁酯)性能良好,在180～190℃间,酯基锡(丁酯)/PVC复合体系的动态热稳定时间>50min,初期着色时间>15min。在双辊塑炼机上混炼20min,体系的透光率从91.61%下降到91.37%,黄度值从1.86增加到3.51,二者均变化很小。酯基锡(丁酯)可以用于制造PVC透明制品和PVC环保制品。更多还原

【Abstract】 Ester-tin (butyl acrylate) was synthesized by mixing solvent and phase transfer catalyst,and was characterized with IR and HNMR.Thermal stability was tested by means of rheometer and Color Quest XE.It was shown that ester-tin (butyl acrylate) exhibited good performance.The dynamic stability time was >50 min and initial stability time was >15 min at 180—190℃ for the ester-tin (butyl acrylate)/PVC compound system.The transparence decreased from 91.61% to 91.37% and yellowness increased from 1.86 to 3.51 after processing over 20 min on the plasticator.Ester-tin(butyl acrylate) can be used to produce PVC transparent products and PVC environmentally friendly products.更多还原
