UNDERSEA ANTIFOULING TREATING COMPOSITION

摘要

As an object and a use of an undersea antifouling treating composition provided by the invention, in order to prevent the adhesion of sessile organisms over a long period of time, the antifouling treating composition is immersed in fish nets for culturing, trapping and the like immersed in sea for a long time and materials such as rope and the like supporting these nets, a net for preventing invasion of jellyfishes at an intake port for cooling water, a curtain for the prevention of marine pollution used in seaside working and the like. As a construction, the first invention is an undersea antifouling treating composition comprising the following ingredients A-C: A) at least one of the following components A1-A5; A1: 2-(thiocycanomethylthio) benzothiazole, A2: tetraethylthiuram disulfide, A3: 2,4,5,6-tetrachloro-1,3-dicycanobenzene, A4: N-(ethylmethylphenyl)-dichloromaleimide, A5: N-(diethylphenyl)-dichloromaleimide, B) film forming substance; C) at least one of dialkylpolysulfides represented by the general formula of R1 - (S)n - R2. The second invention is an undersea antifouling treating composition comprising the above ingredients A-C and further containing the following ingredient D D) polybutene having a polymerization degree of 2-100. As an effect, the above ingredient C or further the ingredient D is compounded with the undersea antifouling treating composition according to the invention, so that the eluting rate of the ingredient A as an antifouling agent is adequately controlled from the surface of the material treated with the composition and immersed in sea, and the antifouling effect can be maintained over a long period of time.
