Polyether amine compound, preparation method thereof and sealing agent

The invention provides a polyether amine compound, a preparation method thereof and a sealing agent. The polyether amine compound has a structure as shown in the following formula (I) or a derivative thereof: # imgabs0 #, R1 and R2 independently represent hydrogen, C1-C10 alkyl substituted or unsubstituted by a substituent group, and C1-C10 alkoxy substituted or unsubstituted by a substituent group, and one of R1 and R2 is H; r represents hydrogen, or C1-C10 alkyl substituted or unsubstituted by a substituent group; in addition, R, R1 and R2 are not H at the same time; x represents any integer from 10 to 33; and y represents any integer from 1 to 20, preferably y represents any integer from 1 to 10. The polyether amine compound provided by the invention can be used for preparing a sealing agent. When the polyether amine compound is used, the obtained sealing agent is excellent in sealing effect, stability and sensitivity. 本发明提供一种聚醚胺化合物及其制备方法及封闭剂。所述聚醚胺化合物具有如下式(I)所示的结构或其衍生物：#imgabs0#其中，R1、R2各自独立地表示氢、取代基取代或未取代的C
