Embodiment

[0140] Hereinafter, although an Example demonstrates this invention more concretely, this invention is not limited to these Examples.

[0141] In addition, in the following examples and comparative examples, "parts" represent parts by weight unless the technical idea of ​​the present invention is clearly violated.

manufacture example 1

[0142] Production Example 1——Preparation of Modified Fluorine-Containing Resin

[0143]

[0144]

[0145] The preparation method is: dissolve vinyl fluoride in 10Kg butanol and add it to the reaction kettle. Then add polychlorotrifluoroethylene and 3g of benzophthalein peroxide that became liquid after heating, stir and heat to 240°C, then slowly add raw materials other than tetrafluoroethylene, and finally add polytetrafluoroethylene and the remaining butanol , reacted at 240°C for 1h. Cool down to below 200°C and add butanone, react at 180°C until the acid value reaches 13mgKOH / g, cool down, add ionized water to dilute until the viscosity (Tu-4 cups 25°C) is 220-320s. Both feeding and reaction are operated under pressure.

[0146] The details of the raw materials of the antifouling paint composition are as follows.

manufacture example 2

[0158] (Manufacture of metal-containing monomer A-1)

[0159] 85.4 parts of propylene glycol monomethyl ether (PGM) and 40.7 parts of zinc oxide 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 75° C. while stirring. Next, a mixture consisting of 50.0 parts of methyl methacrylate (MMA), 36.1 parts of acrylic acid (AA), and 5 parts of water was added dropwise from the dropping funnel at a constant speed over 3 hours. After the dropwise addition, the reaction solution turned from milky white to transparent. After further stirring for 2 hours, 36 parts of propylene glycol monomethyl ether (PGM) was added to obtain a transparent mixture solution A containing metal-containing monomer A-1.

[0160] The solid content (metal-containing monomer A-1) in the obtained mixture solution A was 44.8% by weight. The proportioning composition etc. are shown in Table 2.

Abstract

The invention provides a freshwater domain corresponding type anti-fouling paint composition which is characterized by comprising (A) a polymer containing metal salt bond, wherein the polymer comprises the component unit derived from (meth)acrylic acid metal salt monomer (a1) shown in formula (I) CH2=C(R1)-COO-M-O-CO-C(R1)=CH2, in the formula (I), M is aluminum, zinc or copper, and R1 is respectively independently hydrogen atom or methyl; and (B ) modified fluorine-containing resin. When the freshwater domain corresponding type anti-fouling paint composition is used, an antifouling coating is formed, and the antifouling coating has excellent strength after being immersed in freshwater, can maintain adhesiveness after freshwater immersion at painting interval, is low in consumption degree in seawater after being immersed in freshwater, can maintain moderate coating expendability and is excellent in antifouling property.

Description

technical field [0001] The present invention relates to a freshwater area-compatible antifouling paint composition, its coating film, and an antifouling method, and more specifically, to a freshwater area-compatible type that is originally used in oceans (salt water) but can also be applied to ships built in large rivers (fresh water). Antifouling paint composition, freshwater-compatible antifouling coating film, substrate with freshwater-compatible antifouling coating film, method of forming freshwater-compatible antifouling coating film on substrate surface, and method for antifouling of substrate . Background technique [0002] In China, etc., with the economic development in recent years, not only in harbor areas facing oceans such as the Pacific Ocean, but also in large river basins such as the Yellow River and the Yangtze River, industries have prospered, and the construction of large foreign ships has increased. [0003] However, if the currently known antifouling co...
