Problems solved by technology

If these aquatic organisms multiply on the surface of the substrate, for example, in the case of a ship, the surface roughness of the ship increases, the speed decreases and the fuel cost increases, or, for example, the substrate has an anti-corrosion coating film In the case of the base material, the damage of the anti-corrosion coating film may occur, the strength and function of the base material may be reduced, and the life of the base material may be significantly shortened.

Embodiment

[0147] Hereinafter, the present invention will be specifically described through examples, but the present invention is not limited to these examples. Hereinafter, as long as it does not violate the idea, "parts" refer to parts by weight.

[0148]

[0149] In the present invention, the solid content refers to the heating residue after drying a mixture or composition containing a solvent and the like in a hot air dryer at 105° C. for three hours to volatilize the solvent and the like.

[0150]

[0151] The Mn and Mw of the polymer obtained below were measured using "HLC-8120GPC" manufactured by Tosoh Corporation as a measuring device, using two "TSK-gelα type" separation columns (α-M) manufactured by Tosoh Corporation, 20mM Dimethylformamide (DMF) with LiBr added as an eluent was measured by gel permeation chromatography (GPC). The Mn and Mw are calculated as polystyrene conversion values.

[0152]

[0153] The Gardner viscosity of the polymer obtained below was measured at 25°C.

[0161] [Production Example 2] Production of hydrolyzable copolymer composition (A1-1-2)

[0162] 10 parts of PGM, 37 parts of xylene, and 4 parts of ethyl acrylate were added to a four-necked flask equipped with a cooler, thermometer, dropping funnel and agitator, and the temperature was raised to 100°C while stirring. Next, 15 parts of methyl methacrylate, 52 parts of ethyl acrylate, 8 parts of n-butyl acrylate, and 47 parts of metal atom-containing polymerizable monomer mixture (a1-1) were dropped through a dropping funnel over 2.5 hours at a constant speed. , 10 parts of xylene, 2 parts of chain transfer agent (Nofuma MSD manufactured by NOF Corporation), 3 parts of AIBN and 8 parts of AMBN to form a transparent mixture. After the dripping was completed, 0.5 parts of t-butyl peroxycaprylate and 7 parts of xylene were added dropwise over 30 minutes, and after further stirring for 1 hour and 30 minutes, 3 parts of xylene were added. The obtained mixture was filtered through a 3...

Description

Technical field [0001] The present invention relates to an antifouling coating composition, an antifouling coating film, a substrate having an antifouling coating film, an antifouling substrate, a method for producing a substrate having an antifouling coating film, and an antifouling method for the substrate. Background technique [0002] Among the substrates of fishing gear such as ships, underwater structures, and fishing nets, various aquatic organisms such as oysters, mussels, barnacles and other animals, plants such as seaweed, and bacteria are easily attached to the surfaces of the substrates exposed to water for a long time. If these aquatic organisms multiply on the surface of the substrate, for example, if the substrate is a ship, the surface roughness of the ship will increase and the speed will decrease, and the fuel cost will increase, or, for example, the substrate has an anti-corrosion coating. In the case of the base material, damage to the anticorrosive coating fi...
