Problems solved by technology

However, there are contents such as combining an acid anhydride into the reaction system, and the low-temperature curability is poor when the ambient temperature is below 10°C. The direct reaction between the multifunctional acrylate and the amine in the present invention exhibits low-temperature curability and ensures good coating film properties. The reaction mechanism is different in technical focus

Embodiment

[0210] Hereinafter, the present invention will be described in more detail based on examples and comparative examples, but the present invention is not limited at all by the following examples.

[0211] Manufacturing of hydrolyzed resin:

[0212] ·Manufacturing of side chain terminal type copolymer (a1) containing metal salt bond

manufacture example 1

[0214] 30 parts by weight of propylene glycol monomethyl ether (PGM) and 40 parts by weight of xylene were added to a four-necked flask equipped with a condenser, a thermometer, a dropping funnel, and a stirrer, and the temperature was raised to 100°C while stirring. Next, the mixture composed of the monomers shown in Table 1 and the polymerization initiator was dropped from the dropping funnel at a constant rate over 3 hours. After the dropwise addition, 1 part by weight of tert-butyl peroxyoctanoate and 10 parts by weight of xylene were added dropwise over 2 hours, and after stirring for 2 hours, 20 parts by weight of xylene was added to obtain a side chain terminal type metal salt-containing bond Reaction mixture of copolymer (a1).

[0215] The viscosity and solid content (%) as characteristic values ​​of the obtained copolymer (a1) or the reaction mixture containing the above-mentioned copolymer (a1) were evaluated. The results are shown in Table 1.

manufacture example 2

[0220] [Production Example 2] Production of monomer (a21) containing metal salt bond

[0221] Into a four-necked flask equipped with a condenser, a thermometer, a dropping funnel, and a stirrer, 85.4 parts by weight of propylene glycol methyl ether (PGM) and 40.7 parts by weight of zinc oxide were added, and the temperature was raised to 75° C. while stirring.

[0222] Next, a mixture consisting of 43.1 parts by weight of methacrylic acid (MAA), 36.1 parts by weight of acrylic acid (AA), and 5 parts by weight of water was dropped at a constant speed over 3 hours from the dropping funnel. After the dropping, the reaction solution changed from a milky white state to a transparent state. After stirring for another 2 hours, 36 parts by weight of propylene glycol methyl ether (PGM) were added to obtain a transparent metal salt bond-containing monomer solution (a21). The solid content of the obtained mixture solution of the metal salt bond-containing monomer solution (a21) was 44.8% by ...

Abstract

Provided is a two-part anti-fouling paint composition which can exhibit excellent wastage sustainability and long-term anti-fouling properties against marine organisms. The two-part anti-fouling paint composition according to the present invention is characterized by comprising (A) a first component comprising a (meth)acrylic ester component, (B) a second component comprising an amino-group-containing compound, and (C) an anti-fouling agent contained in either the first component or the second component, wherein the (meth)acrylic ester component (A) and/or the amino-group-containing compound (B) has an ether structure, a trifunctional or higher (meth)acrylic ester is contained in an amount of 50% by weigh or more relative to the total weight of the (meth)acrylic ester component (A), and the amino-group-containing compound (B) is contained in an amount of 20 to 100 parts by weight relative to 100 parts by weight of the (meth)acrylic ester component (A).

Description

Technical field [0001] The present invention relates to a two-component antifouling coating composition, an antifouling coating film composed of the antifouling coating composition, an antifouling substrate, and a method for producing the antifouling substrate. Background technique [0002] In ships, underwater structures, fishing nets, etc., various aquatic organisms such as oysters, mussels, barnacles, and other animals, plants such as seaweed, and bacteria, etc., are easily attached to the surface of substrates immersed in water for a long time. If these aquatic organisms multiply on the surface of the substrate, the surface roughness of the ship will increase, resulting in a decrease in speed and an increase in fuel costs. In addition, the anti-corrosion coating applied on the surface of the substrate will be damaged, and underwater structures will occur. There is a risk of damage such as a decrease in the strength or function of the product, or a significant reduction in lif...
