適用されるものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for producing a biological adhesion prevention composition. This is applied when large quantities of seawater are used, such as in cases where large amounts of seawater are used.

生じるという問題か生じ、また火力発電においては取入
れ口か狭くなるなどという問題が生した。[Conventional Technologies and Issues] As is well-known, materials such as ships, floating islands, buoys, etc. that are kept floating in the sea or river water for long periods of time, power plant pipes, transportation pipes, and other materials related to lumber and seafood. In the case of the ocean, shellfish such as Fujitbo and snails, algae, microorganisms, etc. will adhere to places that are buried in water, and in the case of rivers and lakes, water webs, microorganisms, moss, etc. will adhere to them. Therefore, as they are used for a long period of time, they accumulate, leading to problems such as increased resistance, thickening, and corrosion, and problems such as narrowing of intake ports in thermal power generation.

Measures were taken to prevent or exterminate the growth, or to treat the surface with a coating made of synthetic resin such as Teflon.
しかしながら、従来技術によれば、以下に述べる問題点
を有する。However, the conventional technology has the following problems.
（１）塗料を塗布する場合は、塗料か海水中等に流出す

を要旨とする。The present invention has been made in view of the above-mentioned circumstances, and is intended to significantly reduce the adhesion of biological bodies such as barnacles, snails, and algae to the bottoms of ships, seawater intakes of thermal power plants, etc. [Means for solving the problem] In the present invention, 250 to 650 parts by weight of a mixture consisting of a plasticizer and URA is added to 100 parts by weight of a polyvinyl chloride resin or a copolymer containing polyvinyl chloride, or a stabilizer and a pigment are further added to these. The substance is heated and mixed, and the amount of ura added to the mixture is 10 to 90 parts by weight per 100 parts by weight of the mixture of plasticizer and oil.
本発明に係るポリ塩化ビニルを含む共重合体としては、
例えはポリ塩化ビニルと酢酸ビニルの共重合体等か挙げ

油、廃油等が挙げられる。Examples of the ura according to the present invention include equipment ura, edible oil, insulating oil, waste oil, and the like.
本発明において、上記可塑剤と浦の混合物の添加量は、
ポリ塩化ビニル樹脂又はポリ塩化ビニルを含む共重合体
１００重量部に対し２５０〜６５０重量部とする。この

量部を越えるとセリ−状になりにくくなるためである。In the present invention, the amount of the mixture of plasticizer and ura added is as follows:
The amount is 250 to 650 parts by weight per 100 parts by weight of the polyvinyl chloride resin or copolymer containing polyvinyl chloride. The reason for this is that if the mixture of plasticizer and oil is less than 250 parts by weight, the biological bodies (= 1-wear prevention composition) will become hard and have poor deformability; In addition, the amount of the above-mentioned ura added is 10 to 90 parts by weight per 100 parts by weight of the total plasticizer and oil.The reason for this is ] If it is less than 0 parts by weight, the effect of adding ura cannot be sufficiently exhibited, and if it exceeds 90 parts by weight, it becomes difficult to form a celery.

This solid material is then reheated (approximately 90'
C or higher), it becomes liquid easily. Those who are known to apply a liquid substance to a predetermined location on an object/1. (for example, by spraying) and form it into the desired shape. As a result, even if the object was immersed in seawater or river water for a long period of time, no shellfish or the like was found to be attached to the area to which the composition of the present invention was applied. Further, since the composition can be applied using known methods, it is easy to process and there is no fear of corrosion.
