| titleOfInvention | A kind of polyurethane modified epoxy resin adhesive material and preparation method and application thereof |
| abstract | The invention provides a polyurethane modified epoxy resin adhesive material and a preparation method and application thereof, belonging to the technical field of adhesive materials. In the present invention, the epoxy resin is toughened and modified by using polyurethane, and polytetrahydrofuran diol and toluene-2,4-diisocyanate are used as raw materials for synthesizing the polyurethane prepolymer. The hydroxyl group in the oxygen resin reacts, which will not have a negative impact on the strength while toughening and modifying the epoxy resin, and the polyurethane has a higher polarity and has a higher bonding strength to the cable heat shrinkable tube. The present invention uses 3,3'-dichloro-4,4'-diaminodiphenylmethane as a curing agent, and uses nano-aluminum oxide, graphene and a thickener to adjust the fluidity of the adhesive material, and the obtained adhesive The material is in the form of an elastomer, and when it is thermally cured, it can become a flowable liquid state to fill the sealing gap without dripping, so as to achieve effective bonding and sealing of the gap. |
