Study on toughening epoxy adhesive by IPN
Jun Li · China Adhesives · 2002
The tide structural adhesive consisted of component A-epoxy resin and component B-nBA was prepared by means of interpenetrating polymer networks (IPN) . At the same time, the best compounding of modified epoxy resin adhesive was studied. The results of experiments showed that the maximum of shear strength was 43. 5MPa.The results of humidity-heat experiment showed that the humidity-heat resistance of IPN system was good and the mechanical property of system did not change greatly.
