The present disclosure relates to a method for preparing isophorone diamine by means of a hydrogenation reduction of isophorone nitrile imine. The hydrogenation reduction is continuously carried out in a multi-stage bubble column reactor loaded with a supported alkaline cobalt-based catalyst, wherein isophorone nitrile imine is successively in countercurrent contact with hydrogen in each stage of the reactor to carry out a hydrogenation reduction reaction, so as to obtain the isophorone diamine. The preparation method solves the problem of back-mixing, and further improves the conversion rate and the cis/trans ratio of the product.
