Method for preparing trimethylolpropane-tri-(2-methyl-1-aziridine) propionate

A method for preparing trimethylolpropane-tri-(2-methyl-1-aziridine) propionate comprises the steps of mixing trimethylolpropane with acrylic acid, and adding cerous sulfate, hydroquinone and methylbenzene; conducting stirring heating and reflux reaction, adding water, conducting stirring, conducting stand-layering, and removing liquid on the lower layer; reserving liquid on the upper layer, conducting washing with sodium hydroxide solution and then with saturated sodium chloride solution, and finally conducting washing with water; conducting heating, standing for 30 min, adding hydroquinone, and conducting rotary steaming to obtain faint yellow transparent liquid; placing the transparent liquid in an ice bath, adding 2-methyl aziridine dropwise while stirring, and moving the liquid to a brown bottle; placing the brown bottle at room temperature away from light to obtain trimethylolpropane-tri-(2-methyl-1-aziridine) propionate. The peel strength of a peelable protective film prepared from cured waterborne polyurethane dispersoid is 300-500 n/m.
