| 摘 要： | 考察了各种杂质对加成型硅橡胶中铂催化剂催化活性的影响，对比了不同铝化合物对铂催化剂的防中毒效果，并讨论了催化剂中毒的机理，结果表明，合成的3种防中毒剂即防-1（主要成分为异丙醇铝）、防-2（主要成分为乙酰丙酮合铝）及防-3（主要成分为二乙酰丙酮基异丙氧基铝）对二月桂酸二丁基锡、氯化亚锡、二正丁胺、硫脲、氧化铅及硫酸氢钠等杂质均有较好的防中毒作用；不同防中毒剂对不同杂质的防中毒作用有一定的选择性。

| Abstract: | By using aluminum compound as the poison protection agent for the platinum catalyst of additive type silicone rubber,the effect of some impurity on the catalytic activity of the catalyst and the effctiveness of the agent were studied.The results showed 3 types of aluminum compound prepared in this paper all had good poison protection effectiveness on such impurities as stannous chloride,lead oxide,sodium hydrogen sulfate,and so on.Moreover,the mechanism of the poison of catalyst was also discussed. |
