the molecular structure of the memine-type curing agent there is a 1 thain nitrogen atom and 3 thain nitrogen atoms when it is generally thought that the 3-bit nitrogen atom on the mititoring first makes the epoxy-based open eptomemetrise in epoxy resin when hydrogen atom is present on the 1-bit nitrogen atom The transfer then 1 bit nitrogen atom reacts with epoxy resin to form a 1:2 addition product, and when there is a replacement base on the 1 bit nitrogen atom, 1 bit nitrogen atom does not react with epoxy lipid only 3 bit nitrogen atoms to form a 1:1 addition product to the epoxy-based open epze in epoxy resinIn the above 2 cases, the oxygen negative ions produced by the last epoxy-based open epze continue to catalyze the epoxy epoxy open-loop polymerization
