Preparation of reactive amino silicone oil
摘要
Abstract
Influences of the synthesis of amino silicone oil, polyether and isocyanate grafting process of amino silicone, and residual isocyanate blocking processes on synthetic rate and final product performances were studied. The optimized synthetic process of amino silicone grafted by polyether (reactive amino silicone oil) was determined as following:24%polyether modifier (on weight of the amino silicone oil), reacted at temperature of 75~85℃for 3~4 h. The amino silicone oil was grafted with 70%isocyanate (on content of amino groups in the amino silicone oil) at 55~70℃for 2~4 h. The end-capped ratio of residual isocyanate reaches 65%at 0~5℃for 2~3 h.关键词
