Conventionally, as a countermeasure against this problem, a method of applying an antifouling paint containing an organic tin compound or a copper compound as an antifouling agent to the water-contacted parts of underwater structures has been generally used. However, in recent years, in view of the international situation surrounding Japan's fishing industry, and as coastal aquaculture and set-net fishing have spread and developed, social concern has increased regarding the transfer and residual of environmental pollutants into fish and shellfish, and the spread of harmful contamination has increased. Preventive measures have become an important issue, and the influence of antifouling agents (particularly organic tin compounds) contained in conventional antifouling coatings 1 is also attracting attention.

Therefore, the present inventors have previously proposed a composition comprising liquid paraffin or (andlor) petrolatum blended with oligomeric cold-setting silicone rubber as a non-toxic antifouling paint. (Special Publication No. 60-3433). However, it has been found that the performance of this antifouling paint is unstable depending on the environment in which it is used, such as water temperature, flow velocity, water depth, sea area, etc., the antifouling property decreases in a short period of time, and it has the disadvantage of attracting marine organisms. Ta. The first cause of this was found to be insufficient mixing and dispersibility of the oligomeric silicone rubber and petrolatum or a mixture of petrolatum and liquid paraffin, and the second reason was an inappropriate mixing ratio of petrolatum and liquid paraffin. .

A marine structure has been proposed in which the outer surface is coated with a composition made of a mixture of the following (Japanese Patent Application Laid-Open No. 56-92971@). Furthermore, a method for preventing or reducing bioaccumulation on a seawater contacting surface, which comprises coating the seawater contacting surface with a composition obtained by mixing silicone oil having a viscosity of 20 to 1000 centistokes with a sesame-like silicone rubber.

(Problems to be Solved by the Invention) The present inventors investigated the film-forming properties and antifouling properties of these coating compositions by immersion in the sea, and found that the practical performance of both coating compositions was insufficient. This was recognized. This is because the silicone rubber that forms the coating film has poor compatibility and dispersibility with industrial white oil, methylphenyl silicone oil, etc., which has the disadvantage that these oils quickly separate from the coating film in the sea. However, there is a problem in that the antifouling performance deteriorates in a short period of time, especially in a seawater environment where the flow velocity is high or the temperature is high.

(1) 1 to 100 parts, preferably 5 to 80 parts of petrolatum alone or a mixture of petrolatum and liquid paraffin are mixed with 100 parts of solid content of silicone rubber. If the mixing ratio of these is less than 1 part, the antifouling performance will be extremely reduced.
If the amount exceeds 100 parts, a coating film cannot be formed. Also, in a mixture of petrolatum and liquid paraffin,

(2) Next, 99 to 11 parts, preferably 60 to 20 parts, of silicone oil are further mixed into the mixture of (1) above, and the mixture is thoroughly stirred in a container using a stirrer until the entire mixture becomes uniform. If the amount of silicone oil is less than 11 parts, the compatibility and dispersion of petrolatum or petrolatum/liquid paraffin mixture with silicone rubber will be poor, and the antifouling performance will deteriorate in a short period of time, which is not preferable. Moreover, if it exceeds 99 parts, it is not practical because the coating film remains sticky and the adhesion to the undercoat is inhibited. The silicone oil used is methyl silicone oil or methylphenyl silicone oil, which has a viscosity (at 25° C.) of 0.65 centistokes or more and does not exceed 20 centistokes. There are no silicone oil products on the market that are less than 0°65 centistokes. At 20 centistokes or more, the above-mentioned compatibility and dispersibility decreases. The silicone oil may be used alone or as a mixture, such as methyl silicone oil or methyl phenyl silicone oil, a mixture of methyl silicone oil and methyl phenyl silicone oil, a mixture of methyl silicone oils, or a mixture of methyl phenyl silicone oils. Also,
Among these, it is also possible to use at least two types of silicone oil in the mixed oil, at least one of which is a low viscosity oil and the remaining one is a high viscosity oil.

In the composition prepared in this way, by adding the low-viscosity silicone oil, the compatibility and dispersion of petrolatum or petrolatum/liquid paraffin mixture in silicone rubber is extremely good, and the fine colloidal mixed state of these substances is improved. can get. Therefore, the composition can maintain good antifouling performance over a long period of time,
Moreover, by changing the composition, a composition that can be appropriately adapted to various seawater environments can be obtained. The reason for this is that the mixture of silicone rubber and petrolatum or petrolatum/liquid paraffin and silicone oil is stable as a composition in phase equilibrium, and in the coating state, the mixture of petrolatum or petrolatum/liquid paraffin and silicone oil is coated. This is because the coating film with low surface free energy is maintained for a long period of time because it is oriented uniformly and densely on the surface of the silicone rubber that is the film matrix.

As explained above, the composition of the present invention can be prepared by mixing silicone rubber, Pel-loratum alone or a mixture of petrolatum and liquid paraffin having a certain viscosity range, and further low-viscosity silicone oil. Compared to antifouling paint compositions made by mixing silicone rubber with petrolatum, liquid paraffin, silicone oil (medium to high viscosity oil), etc., the antifouling performance is markedly improved, and the antifouling performance is significantly improved. The ability to select appropriate antifouling performance according to various seawater environments has become extremely advantageous for industry.

以上that's all
