Problems solved by technology

If these aquatic organisms multiply on the surface of the base material, the surface roughness of the ship will increase, resulting in a decrease in speed and an increase in fuel consumption. In addition, the anti-corrosion coating coated on the surface of the base material may be damaged, and structures in the water may be formed. Hazards such as reduced strength, reduced function, and significantly shortened lifespan
In addition, if aquatic organisms attach to and reproduce on fishing nets such as breeding nets and fixed nets, serious problems such as death due to hypoxia caused by mesh clogging may occur.
In addition, if aquatic organisms adhere to and multiply on seawater supply and drainage pipes of thermal power plants, nuclear power plants, etc., it may hinder the circulation of water supply and drainage of cooling water

Embodiment 1

[0149] (Example 1: Manufacture of polyester resin solution (a-1))

[0150] In a reaction vessel with a stirrer, a condenser, and a thermometer, 92 parts of glycerol as (a) a tribasic or higher alcohol, 444 parts of phthalic anhydride as (b) a dibasic acid or an anhydride thereof, and 444 parts as (c) 228 parts of dihydric alcohol propylene glycol and 0.05 part of tetrabutyl titanate as a catalyst were subjected to an esterification reaction from 140° C. to 190° C. over 4 hours. Then, the pressure in the system was gradually reduced to 100 mmHg over 2 hours, and polycondensation reaction was performed at 190°C for 20 hours. During the reaction, the generated water is removed by reflux dehydration, and the acid value measurement by KOH titration method and the hydroxyl value measurement by acetylation method are carried out. When the acid value of the solid component reaches less than or equal to 1mgKOH / g, cool to 120°C and add (d) 439 parts of hexahydrophthalic anhydrides whic...

[0151] (Examples 2-7, 26-31: Manufacture of polyester resin solutions (a-2)-(a-7), (a-13)-(a-18))

[0152] Except for changing the types and amounts of raw materials as shown in Table 1, polyester resin solutions (a-2) to (a-7), (a-13) to (a) were obtained in the same manner as in Production Example 1. -18).

Embodiment 8

[0203] An antifouling paint composition was prepared as follows.

[0204] First mix xylene (10.5 parts), methyl isobutyl ketone (2 parts), WW rosin (5.5 parts), TCP (5 parts), polyester resin solution (a-1) ( 8 parts), BYK-101 (0.3 parts), ethyl silicate 28 (0.3 parts), stirred with a pigment shaker until uniformly dissolved.

[0205] Then, with TTK talc (4 parts), zinc oxide (6 parts), NOVAPERM RED F5RK (0.6 parts), cuprous oxide NC-803 (48 parts), 2-methylthio-4-tert-butylamino-6 - Cyclopropylamino-s-triazine (2.5 parts), Iron Oxide Red 404 (2.3 parts), Titanium White R-5N (2 parts), Calcined Plaster (1 part), Disperlon 603-20X (2 parts), Add glass microspheres (200 parts), and disperse for 1 hour.

[0206] Filtrate with an 80-mesh filter to prepare an antifouling paint composition.

Abstract

The purpose of the present invention is to provide: a polyester resin for antifouling coating materials, which enables an antifouling coating material to be in a one-pack form by improving storage stability, while maintaining low VOC level, and which is capable of improving curability, while providing long-lasting good antifouling properties and good coating film properties; a method for producing the polyester resin for antifouling coating materials; and an antifouling coating material composition. A polyester resin for antifouling coating materials is obtained by reacting (a) a tri- or higher hydric alcohol, (b) a dibasic acid or an anhydride thereof and (c) a dihydric alcohol, and then reacting the resulting product with (d) an alicyclic dibasic acid or an anhydride thereof.

Description

technical field [0001] The present invention relates to a polyester resin for antifouling paint, a method for producing the same, an antifouling paint composition containing the polyester resin, an antifouling coating film and an antifouling substrate using the antifouling paint composition. Background technique [0002] For ships, underwater structures, fishing nets, etc., animals such as oysters, mussels, and barnacles, plants such as seaweed, and various aquatic organisms such as bacteria tend to adhere to the surface of the substrate exposed to water for a long time. If these aquatic organisms multiply on the surface of the base material, the surface roughness of the ship will increase, resulting in a decrease in speed and an increase in fuel consumption. In addition, the anti-corrosion coating coated on the surface of the base material may be damaged, and structures in the water may be formed. The strength, function reduction, and life-span are significantly shortened. ...
