Fluorine-containing cross-linking agent and preparation method thereof

The invention discloses a fluorine-containing cross-linking agent, which has the following structural formula: # imgabs0 # R is an aliphatic or aromatic fluorine-containing group. Compared with the prior art, the fluorine-containing cross-linking agent has the beneficial effects that 4-vinylpyridine-2-amine and fluorine-containing acyl chloride are subjected to amidation reaction to obtain the intermediate A, the intermediate A and 2, 4, 6-tri (4-bromomethyl phenyl)-1, 3, 5-triazine are subjected to quaternization reaction to obtain the fluorine-containing cross-linking agent, the preparation method is simple, the product quality is stable, and the fluorine-containing cross-linking agent is convenient to use. 本发明公开了一种含氟交联剂，具有如下结构式：#imgabs0#R为脂肪族或芳香族含氟基团。与现有技术相比，本发明的有益效果是：本发明通过4-乙烯基吡啶-2-胺中与含氟酰氯进行酰胺化反应，得到中间体A，中间体A与2,4,6-三(4-溴甲基苯基)-1,3,5-三嗪进行季铵化反应，得到含氟交联剂，制备方法简单，产品质量稳定，使用方便。
