The invention discloses a synthesis method of an ultraviolet light absorber UV-1600. The method is composed of four steps of reactions: using 4-cyanobiphenyl and urea as raw materials, and carrying out cyclization reaction in the presence of a basic catalyst to obtain 2, 4-bis([1, 1'-biphenyl]-4-yl)-6-hydroxyl-1, 3, 5-triazine, then carrying out chlorination reaction under the action of a chlorination reagent to obtain an intermediate 2, 4-bis([1, 1'-biphenyl]-4-yl)-6-chloro-1, 3, 5-triazine, carrying out alkylation reaction on the intermediate and resorcinol, and then carrying out etherification reaction on the intermediate and halogenated isooctane to obtain UV-1600. The UV-1600 has an important application prospect in the field of ultraviolet light stabilizers due to the good performance of the UV-1600.
