Abstract

A method for manufacturing an organism adhesion reduction paint includes a first process of gelling a raw material composition that includes polyvinyl alcohol and at least one of a hydroxyl group-containing inorganic compound or an inorganic oxide; a second process of drying and subsequently pulverizing a resulting product in the first process to thereby obtain a composite gel fine powder; and a third process of adding the composite gel fine powder to a main component of a two-component urethane paint and stirring, to thereby prepare a main component of the organism adhesion reduction paint, and also adding a curing agent immediately before use.

First claim

The invention claimed is:

1. A method for manufacturing an organism adhesion reduction paint, the method comprising:
a first process of gelling a raw material composition that comprises polyvinyl alcohol and at least one of a hydroxyl group-containing inorganic compound or an inorganic oxide;
a second process of drying and subsequently pulverizing a resulting product in the first process to thereby obtain a composite gel fine powder; and
a third process of adding the composite gel fine powder to one component of a two-component urethane paint and stirring, to thereby prepare one component of the organism adhesion reduction paint, and adding a curing agent immediately before use.

2. The method for manufacturing an organism adhesion reduction paint according to claim 1 ,
wherein the polyvinyl alcohol has a viscosity-average polymerization degree of 350 to 3500 and a saponification degree of 50 to 100 mol %.

3. The method for manufacturing an organism adhesion reduction paint according to claim 1 ,
wherein the hydroxyl group-containing inorganic compound is one, or two more selected from the group consisting of a hydroxyl group-containing silicon compound, aluminum hydroxide, magnesium hydroxide, and iron hydroxide.

4. The method for manufacturing an organism adhesion reduction paint according to claim 3 ,
wherein the hydroxyl group-containing silicon compound is silica.

5. The method for manufacturing an organism adhesion reduction paint according to claim 4 ,
wherein the silica is silica sol or silica gel.

6. The method for manufacturing an organism adhesion reduction paint according to claim 1 ,
wherein the inorganic oxide is one, or more selected from the group consisting of aluminum oxide, magnesium oxide, and iron oxide.

7. The method for manufacturing an organism adhesion reduction paint according to claim 1 ,
wherein the composite gel is compounded from the polyvinyl alcohol and the hydroxyl group-containing inorganic compound, or from the polyvinyl alcohol and the inorganic oxide.

8. The method for manufacturing an organism adhesion reduction paint according to claim 1 ,
wherein 10 pts. by wt. of the composite gel fine powder is added to 100 pts. by wt. of the one component of the two-component urethane paint.
