Put 45kg of dimethylpropylamine and 1.7kg of diethylenetriamine into the reactor in sequence, then add 300L of ethanol, stir and dissolve. In addition, 56kg of hexamethylene 1,6-diisocyanate and 60L of ethanol were added to the dissolution tank and dissolved below 10 ℃. Then slowly add an ethanol solution of hexamethylene 1,6-diisocyanate to the reactor and stir at room temperature for 1 hour. After precipitation, stir for 1-2 hours. Filter, vacuum dry the filter cake at 65 ℃ for 24 hours, and crush to obtain the finished product
