Disclosed by the present invention is a method for preparing a reactive sealant resin, the method comprising: (1) under the action of an alkali catalyst, polymerizing a hydroxyl-containing initiator with an epoxy compound to obtain a polyether polyol; (2) adding an alkoxide reagent and a halogenated end-capping agent containing a double bond to the polyether polyol obtained in step (1) for reaction, so as to obtain a crude double-bonded polyether product, and refining the crude product to obtain a modified polyether product; and (3) subjecting the modified polyether and hydrogen-containing silane to silane end-capping reaction under the action of a hydrosilylation catalyst, so as to obtain the target product, i.e., a reactive sealant resin. The resin has excellent properties as well as good adhesion and paintability.
