多活性基阳离子接枝剂的制备方法
摘要：
多活性基阳离子接枝剂的制备方法：在0-10℃的三聚氯氰水悬浮液中加入N，N-二甲基丙二胺或N，N-二甲氨基乙醇、N，N-二甲氨基丙醇的盐酸盐溶液，三聚氯氰与N，N-二甲基丙二胺或N，N-二甲氨基乙醇、N，N-二甲氨基丙醇的摩尔比为1∶0.34，用碱调节控制pH为3-4，反应完全后升温至35-45℃，再加入N，N-二甲基丙二胺或N，N-二甲氨基乙醇，N，N-二甲基丙二胺或N、N-二甲氨基乙醇与三聚氯氰的摩尔比为0.4∶1，反应完全后用盐酸调整pH为1-2，升温至70-85℃，加入环氧氯丙烷，环氧氯丙烷与三聚氯氰的摩尔比为0.7∶1，反应后得到一氯均三嗪氯化铵衍生物。本发明的接枝剂用于织物接枝改性，以提高染色效果。
摘要（英）：

The invention relates to a method for preparing a cationic grafting agent with multi-reactive groups, which comprises the following steps: adding N,N-dimethyl diaminopropane or N,N-dimethylaminoethanol and hydrochloride solution of N,N-dimethylamino propanol into cyanuric chloride water suspension at the temperature of 0-10 DEG C, leading the molar ratio of cyanuric chloride to the N,N-dimethyl diaminopropane or the N,N-dimethylaminoethanol and the N,N-dimethylamino propanol to be 1: 0.34, using base for adjusting and controlling the pH to be 3-4, increasing the temperature to 35-45 DEG C after full reaction, and further adding the N,N-dimethyl diaminopropane or the N,N-dimethylaminoethanol, leading the molar ratio of the N,N-dimethyl diaminopropane or the N,N-dimethylaminoethanol to the cyanuric chloride to be 0.4:1, using hydrochloric acid for adjusting the pH to be 1-2 after full reaction, increasing the temperature to 70-85 DEG C, adding epichlorohydrin, leading the molar ratio of the epichlorohydrin to the cyanuric chloride to be 0.7:1, and obtaining a monochlorotriazine ammonium chloride derivative. The grafting agent is used for graft modification of fabric, thereby improving the dyeing effect.
