[0222] [Manufacture Example 1: Manufacture of Polyester Resin Solution (a-1)]

[0223] 371.0 parts of isophthalic acid, 427.1 parts of sebacic acid, 238.2 parts of neopentyl glycol and 89.0 parts of ethylene glycol were mixed in a 2L four-necked flask, and reacted at 220° C. for 5 hours in the presence of nitrogen (esterification reaction) . During the reaction, the generated water was removed by reflux dehydration, the acid value was measured by the KOH titration method, and the hydroxyl value was measured by the acetylation method. The acid value of the solid component in the reaction solution reached 100mgKOH / g, and the hydroxyl value of the solid component reached The reaction was stopped at 30mgKOH / g. After cooling the reaction solution, it was diluted with methyl isobutyl ketone to obtain a resin composition (polyester resin solution (a-1)) having an acid value of 70 mgKOH / g, a hydroxyl value of 21 mgKOH / g, and a solid content of 70.3%. As shown in Table 1, the solid con...

Remove the generated water by reflux dehydration, measure the acid value by KOH titration method, and measure the hydroxyl value by acetylation method. The acid value of the solid component in the reaction liquid reaches 43mgKOH / g, and the hydroxyl value of the solid component reaches 115mgKOH / g. stop responding. Then cool to 170° C., add 108.0 parts by weight of trimellitic anhydride, keep warm for 2 hours to carry out addition reaction, and stop the reaction when the acid value of the solid component in the reaction liquid reaches 90 mgKOH / g, and the hydroxyl value of the solid component reaches 60 mgKOH / g.

Abstract

[Problem] To provide an antifouling paint composition which, while reducing volatile organic compounds (VOCs), has good coating workability at low temperatures as well as at room temperature, and which is capable of forming coating films having excellent mechanical strength and good long-term antifouling properties. [Solution] The two-component hydrolyzable antifouling paint composition includes two liquids that are a first component and a second component, the first component being a liquid including a reaction mixture (A) including a polyester resin (a3) obtained by polycondensation of an acid component (a1) and a polyhydric alcohol component (a2), and an acetoacetyl group-containing compound (B), the second component being a liquid including zinc oxide (C), the solid component of the reaction mixture (A) having an acid value and a hydroxyl value of 50 to 200 mgKOH / g and 100 mgKOH / g or less, respectively, and the two-component antifouling paint composition substantially not containing copper and copper compounds.

Description

technical field [0001] The present invention relates to a two-component hydrolyzable antifouling paint composition capable of imparting excellent antifouling properties to the surface of substrates such as ships, underwater structures, fishing nets, fishing gear, etc., while reducing the burden on the environment and the impact on the human body , and an antifouling coating film formed by curing the coating composition, and a method for producing an antifouling substrate using the antifouling coating composition. Background technique [0002] Various aquatic organisms such as oysters, mussels, barnacles and other animals, seaweed and other plants, and bacteria are likely to adhere to the surface of substrates exposed to water for a long time, such as ships, underwater structures, and fishing nets. If these aquatic organisms attach to the substrate surface and reproduce, the following adverse situations may be incurred. [0003] For example, when aquatic organisms adhere to ...
