| Abstract: | A latent and flexible epoxy curing agent was synthesized by the reaction of synthetic epoxy compound and ketimine which was synthesized by diethylenetriamine and methyl isobutyl ketone.And the synthetic epoxy compound having a long hydrophobic alkyl side chain on the N atom and terminated by epoxy groups was synthesized from octadecanamine and the ethylene glycol diglycidyl ether.And a type of flexible epoxy grouting material was prepared based on the curing agent.By means of checking the impact strength,te... |
