The invention relates to a method for improving the binding strength of a silica gel surface material and instantaneous adhesive. A matter containing active amine is introduced into the surface of silica gel, an epoxy functional group silane coupling agent is introduced into the instantaneous adhesive, curing of the instantaneous adhesive is catalyzed to be accelerated through active amine matterat the interface, the instantaneous adhesive react with epoxy groups, and thus the bonding strength of the interface is improved. According to the method, the problem that existing silica gel materials such as sealing gel, electronic potting gel, human organ models, silica gel molds and silica gel human body models are difficulty repaired through the instantaneous adhesive after being damaged issolved, and an improvement formula of the silica gel material and the instantaneous adhesive is provided.
