Benzyl tertiary amine, preparation method and applications thereof

The invention relates to benzyl tertiary amine and a preparation method thereof, and applications of the benzyl tertiary amine in preparation of marine antifouling coating materials. According to the present invention, during the preparation, 3,4-dihalo substituted benzyl chloride reacts with secondary amine in the presence of an alkaline substance; the benzyl tertiary amine can be used for preparation of marine antifouling coating materials, and the marine antifouling coating material comprises one or a plurality of materials selected from, by weight, 25-60% of a copper acrylate resin solution, 1-20% of a plasticizer, 1-30% of a filler, and 5-40% of benzyl tertiary amine or cuprous oxide or tetramethylthiuram disulfide or pyridinethione salt (copper salt or zinc salt) or pyridine-triphenylborane or Seanine-211; and the raw materials are simple and easy to obtain, the preparation process is simple and feasible, and the benzyl tertiary amine can be used as the antifouling agent of the marine antifouling coating material, and has the environmental protection advantage.
