摘要：The curing behaviors and heat resistance of bisphenol F epoxy resin/DHPZ
- DA bonding system using 1,2- dihydro -2 - (4 - aminophenyl) -4 -[4- (4
- aminophenoxyl) phenyl] - phthalazin -1 - one(DHPZ - DA) as curing
agent were investigated by DSC, TGA, infrared spectroscopy and shear
strength testsing. The curing apparent activation energy were 80.1
kJ/mol and 84.3 kJ/mol calculated by the Kissinger and Ozawa methods,
respectively. The apparent reaction order obtained by the Crane equation
was 0.93. The T_g of the adhesive system was higher than 200 ℃. The
shear strength at room temperature and after aging at 150℃ for 24 h of
the system with molar ratio of bisphenol F epoxy resin to DHPZ - DA 10:4
were greater than 12MPa and showed good heat resistance.
