The present invention relates to a long-acting underwater antifouling agent for preventing the attachment of underwater fouling organisms to ships, fishing nets, various underwater structures, etc. Conventionally, fishing nets, especially aquaculture nets and fixed nets, are kept in water for long periods of time, so they are heavily contaminated with aquatic fouling organisms.
As a result, they are suffering from various obstacles. That is,
In addition to seaweed such as sea lettuce and green laver, aquaculture nets are especially prone to accumulating animal barnacles, serpura, and bulrushes, which impede water circulation, cause oxygen deficiency, and harm the survival of farmed fish. At the peak of life, the nets must be replaced every few weeks. This rewiring requires effort, time, and
Considering various factors such as the negative impact on farmed fish, this is a considerable loss. Therefore, preventing the attachment of water-fouling organisms is a serious issue. In addition, prevention of adhesion to the bottom of ships and various other underwater facilities is one of the important issues to be solved in order to maintain their functions sufficiently and economically. Various antifouling active ingredients have been proposed to prevent the adhesion of these aquatic fouling organisms. Copper compounds and organic tin compounds are generally used. Practically effective compounds include trialkyltin compounds and triphenyltin compounds. However, this organotin compound is generally highly toxic, and products containing it may cause injury to the handler if handled carelessly. In view of the current situation, the present inventors have developed an environmentally friendly compound that is less toxic to the human body and to fish and shellfish than organic tin compounds that are currently commonly used, and which has recently become a social issue. The present invention was completed as a result of intensive research to develop a low-toxicity, low-pollution underwater antifouling agent with consideration given to pollution. The present inventors screened many compounds, found an effective compound based on the results of a sea immersion test, and also pursued a synergistic effect in order to effectively prevent the attachment of a wide variety of aquatic fouling organisms, and developed the present invention. I've reached it. That is, the present invention is an underwater antifouling agent containing tetrachloroisophthalonitrile and tributyltin polymer compounds as active ingredients, which exhibit excellent synergistic effects and can be used alone against a wide range of aquatic fouling organisms. It has been found that in some cases, the anti-adhesion effect is so excellent that it cannot be estimated. As the tributyltin polymer compound used as an active ingredient in the present invention, triorganotin salt monomers of unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid, and itaconic acid are synthesized, and homopolymers of these monomers are prepared. or copolymers with each other and unsaturated compounds with copolymerizability such as vinyl chloride, vinyl acetate, vinylidene chloride, alkyl esters of acrylic acid or methacrylic acid, styrene, vinyltoluene, etc. Examples include polymer compounds obtained by reacting carboxyl groups of acid-valued alkyd resins or acrylic resins with tributyltin compounds. The blending ratio of tetrachloroisophthalonitrile and tributyltin polymer compound of the present invention is not particularly specified, but can be blended in any ratio from the viewpoint of antifouling performance and economical efficiency. In producing the underwater antifouling agent of the present invention, tetrachloroisophthalonitrile and tributyltin polymer compound are dispersed and kneaded together with a spreading agent, a solvent, and if desired, a pigment, a filler, etc. using a conventional method such as a ball mill. do it. Examples of the spreading agent include natural resins, oil-based resins, and synthetic resins, but preferably polybutene, acrylic resin, rosin vinyl resin, chlorinated rubber, and the like. Hereinafter, the present invention will be explained in detail by giving examples. Production example 1 Synthesis of tributyltin polymer compound 350g of tributyltin methacrylate and 150g of methyl methacrylate were dissolved in 500g of xylene, 2.5g of benzoyl peroxide was added as a polymerization initiation catalyst, and polymerization was carried out at 90 to 110°C for 7 hours to form a pale yellow viscous substance. The number average molecular weight of the copolymer is 17,000 according to gel permeation chromatography. Production example 2 Synthesis of tributyltin polymer compound Tributyltin methacrylate 325g, methyl methacrylate 125g and butyl acrylate 50g
g is dissolved in 500 g of xylene, 2.5 g of benzoyl peroxide is added as a polymerization initiation catalyst, and polymerization is carried out at 80 to 100° C. for 8 hours to obtain a 50% xylene solution of a pale yellow and viscous copolymer. The number average molecular weight of this copolymer was determined by gel persion chromatography.
It is 21000.

(From the book) After dipping and drying in a 30cm x 50cm area, it was kept in the sea at a depth of about 1m in Toba Bay, Mie Prefecture, for 6 months from April 1980 to October 1980, and fouling organisms were attached every month. We investigated the situation. The results are shown in Table 1. In the table, ratings A, B, C, and D represent the degree of adhesion of fouling organisms. A: No fouling organisms attached B: Slight amount of fouling organisms attached C: Fouling organisms attached to the net, making it no longer usable as an aquaculture net. D: Fouling organisms are significantly attached.
