description Disclosed are an additive and application thereof, and a samarium-cobalt 2: 17 type magnet and a preparation method thereof. The additive includes the following components by mass percentage: 20-30% of organocopper complex, 0.5-1% of plasticizer, and an organic solvent, and the sum of the mass percentages of the components is 100%. The organocopper complex is an oil-soluble substance, the mass percentage of Cu in the organocopper complex is greater than 10%, and the organocopper complex contains a polar group and/or an alkyl chain having more than 3 C atoms. The preparation method of a Sm2Co17 permanent magnet of the present invention can greatly eliminate adverse effects brought by the phenomenon of copper depletion at grain boundaries without reducing the remanence, thereby improving the coercivity, squareness, and magnetic energy product of products.
