摘要：Although multifunctional epoxy resin adhesive is characteristic of good heat resistant, it is brittle. Therefore, tough epoxy adhesive with outstanding comprehensive properties is in demand. In this work, a novel phenolic curing agent based on phenylene ether (HPF) was prepared from resorcinol, formaldehyde and diphenyl ether, which could improve the toughness of AFG-90 H epoxy resin due to the phenylene ether. At the same time, carboxyl -terminated butadiene acrylic liquid rubber (CTBN) and organic montmorillonite (OMMT) was introduced into AFG-90 H epoxy resin to enhance the comprehensive properties. It was shown that phenolic curing agent based on phenylene ether (HPF) can lower the curing temperature of AFG-90 H resin to 70 degrees C. Also, when 15 wt% OMMT were added into AFG-90 H grafted by 5 wt% CTBN cured by HPF, the degradation temperature (Td5%) is above 360 degrees C and the tensile strength, flexural strength and shear strength are up to 71.72 MPa, 67.34 MPa and 13.88 MPa, respectively. Meanwhile, the maximum impact strength can reach 11.00KJ/m2. The synergistic effect of HPF, OMMT and CTBN can make the cured AFG-90 H resin with good comprehensive properties.
