The invention discloses a preparation method of 2, 4, 6-tri(N-1, 4-dimethylamyl-p-phenylenediamine)-1, 3, 5-triazine. The preparation method comprises the following steps: carrying out catalytic hydrogenation reaction on p-aminoacetanilide and methyl isoamyl ketone to obtain N-1, 4-dimethylamyl-p-acetanilide; removing acetyl from N-1, 4-dimethylamyl-p-acetanilide in an alkali solution, so as to obtain N-1, 4-dimethylamyl-p-aniline; and carrying out substitution reaction on cyanuric chloride and N-1, 4-dimethylamyl-p-phenylenediamine, and carrying out after-treatment to obtain the 2, 4, 6-tri(N-1, 4-dimethylamyl-p-phenylenediamine)-1, 3, 5-triazine. The method has the advantages of high reaction selectivity and yield, few byproducts, low cost and good quality.
