Description

本発明は、養殖用または定置網用の漁網およびこれらに使用される浮き子、ロープなどの漁網用具(以下、これらを併せて魚網類という場合がある)、および発電所の冷却水導管などの水中構築物などに水棲汚損生物が付着するのを長期にわたって防止するための防汚塗料組成物、該塗料組成物を用いて形成される防汚塗膜、該塗膜を表面に有する水中構築物、および該塗膜を形成する防汚処理方法に関する。  The present invention relates to fishing nets for aquaculture or stationary nets and fishing net equipment used therefor, such as floats and ropes (hereinafter also referred to as fish nets), and underwater such as cooling water conduits for power plants. An antifouling paint composition for preventing the adhesion of waterpox fouling organisms to a structure or the like over a long period of time, an antifouling coating film formed using the coating composition, an underwater structure having the coating film on the surface, and the The present invention relates to an antifouling treatment method for forming a coating film.

漁網、漁網用具などの水中構築物は、海水中に長期間設置されるため、防汚塗料組成物を塗布せずに使用すると、海藻類、フジツボ、セルプラ、コケムシ、軟体動物類などの種々の水棲汚損生物が付着し、海水の流れが悪くなり酸素欠乏で養殖魚が大量に死んだり、伝染病が発生し出荷できなくなったりし、大きな損害を受けることがある。  Underwater structures such as fishing nets and fishing net tools are installed in seawater for a long period of time, so if they are used without applying an antifouling paint composition, various water tanks such as seaweeds, barnacles, cell plastics, bryozoans, mollusks, etc. Soiled organisms may be attached, the flow of seawater will be worse, and a large amount of cultured fish will die due to lack of oxygen, or infectious diseases will occur, making it impossible to ship, and serious damage may occur.

これらの水棲汚損生物の付着を防止するために、従来は有機錫化合物を用いた漁網用防汚塗料組成物が広く使用されてきたが、環境に対する配慮などから使用できなくなった。
そこで、有機錫化合物に替わる防汚塗料組成物として、種々の研究、提案がなされ、無機化合物や有機化合物を防汚薬剤として用い、これを天然樹脂系または合成樹脂系展着樹脂に配合した防汚塗料組成物が使用されてきている。しかし、これらは塗膜物性が悪く、防汚効果が持続する期間が短い等の問題がある。それらの問題を解決すべく、展着樹脂に薬剤の溶出コントロール剤として特定のポリエーテル変性シリコーンオイルを配合した防汚塗料組成物が提案されている(特許文献1〜4、8)。
これらの提案により、塗膜物性が良くなり多くの海域では防汚性能が改良されたが、フジツボやセルプラ等の動物類の活性が強い海域や、ヒドロ虫等の腔腸動物の活性が強い海域では、効果が充分ではなかった。
また、ヒドロ虫等の腔腸動物に対して優れた防汚塗料組成物として、ビスジメチルジチオカルバモイルジンクエチレンビスジチオカーバメートと特定のポリエーテル変性シリコーンオイルを配合した水中防汚塗料組成物が提案されている(特許文献5)。また、フジツボやセルプラ等の動物類やヒドロ虫等の腔腸動物に対して優れた防汚塗料組成物として、亜酸化銅と特定のポリエーテル変性シリコーンオイルを配合した水中防汚塗料組成物が提案されている(特許文献6)。更に、腔腸動物、フジツボ、海草に優れた防汚塗料組成物として、特定量のエチレンオキシ基と特定量のプロピレンオキシ基の両方を含有し、オキシアルキレン基含有オルガノポリシロキサン(ポリエーテル変性シリコーン)を配合した水中防汚塗料組成物が提案されている(特許文献7)。
しかし、これらの発明は、それぞれ、ビスジメチルジチオカルバモイルジンクエチレンビスジチオカーバメートはヒドロ虫等の腔腸動物に対して、亜酸化銅はフジツボやセルプラ等の動物類に対して、優れた防汚効果を発揮するが、これらの発明に使用されている分子構造のシリコーンオイルは、初期の防汚効果は良くなるものの防汚薬剤が早期に溶出してしまうため、長期間防汚効果を維持することが出来ないという問題がある。
そのため、塗膜物性が良く塗布時の作業性に優れ、フジツボやセルプラ等の動物類やヒドロ虫等の腔腸動物の活性が強い海域において、設計通りに長期間防汚効果を発揮できる防汚塗料組成物の開発が切望されている。

Conventionally, antifouling paint compositions for fishing nets using organotin compounds have been widely used to prevent the adhesion of these waterpox fouling organisms, but they cannot be used because of environmental considerations.
Therefore, various researches and proposals have been made as antifouling paint compositions to replace organic tin compounds, and inorganic compounds and organic compounds are used as antifouling agents, which are blended with natural resin or synthetic resin spreading resins. Dirty paint compositions have been used. However, these have problems such as poor physical properties of the coating film and a short period in which the antifouling effect is sustained. In order to solve these problems, antifouling coating compositions in which a specific polyether-modified silicone oil is blended with a spreading resin as a drug elution control agent have been proposed (Patent Documents 1 to 4, 8).
These proposals have improved film properties and improved antifouling performance in many sea areas, but sea areas with strong activity of animals such as barnacles and cell plastics and sea areas with strong activity of coelenterates such as hydroworms Then, the effect was not enough.
In addition, an underwater antifouling paint composition comprising bisdimethyldithiocarbamoyl zinc ethylene bisdithiocarbamate and a specific polyether-modified silicone oil has been proposed as an antifouling paint composition excellent for coelenterates such as hydroworms. (Patent Document 5). In addition, as an antifouling paint composition excellent for animals such as barnacles and cell plastics and coelenterate animals such as hydroworms, an underwater antifouling paint composition containing cuprous oxide and a specific polyether-modified silicone oil is provided. It has been proposed (Patent Document 6). Furthermore, as an antifouling paint composition excellent for coelenterate, barnacles and seaweeds, it contains both a specific amount of ethyleneoxy groups and a specific amount of propyleneoxy groups, and an oxyalkylene group-containing organopolysiloxane (polyether-modified silicone). ) Has been proposed (Patent Document 7).
However, these inventions show that bisdimethyldithiocarbamoyl zinc ethylene bisdithiocarbamate has excellent antifouling effects on coelenterates such as hydroworms, and cuprous oxide on animals such as barnacles and cell plastics. However, the molecular structure silicone oil used in these inventions improves the initial antifouling effect, but the antifouling agent elutes early, and therefore maintains the antifouling effect for a long period of time. There is a problem that cannot be done.
For this reason, antifouling can be applied for a long period of time as designed in sea areas where the coating film properties are good, the workability at the time of application is excellent, and the activity of animals such as barnacles and cell plastics and the activity of coelenterate such as hydroworms is strong. Development of coating compositions is eagerly desired.

<展着樹脂[B]>
本発明に用いられる展着樹脂[B]としては、合成樹脂および/または天然樹脂が用いられる。
<Spreading resin [B]>
As the spreading resin [B] used in the present invention, a synthetic resin and / or a natural resin is used.

合成樹脂としては、塩化ビニル/酢酸ビニル共重合体、塩化ビニル/アルキルビニルエーテル共重合体、塩化ビニル樹脂などのビニル樹脂系、アルキッド樹脂系、(メタ)アクリル樹脂系、ウレタン樹脂系、ポリエステル樹脂系、合成ゴム系、塩素化ポリエチレンなどが挙げられる。  Synthetic resins include vinyl chloride / vinyl acetate copolymer, vinyl chloride / alkyl vinyl ether copolymer, vinyl resin such as vinyl chloride resin, alkyd resin, (meth) acrylic resin, urethane resin, polyester resin , Synthetic rubber type, chlorinated polyethylene and the like.

天然樹脂としては、ウッドロジン、ガムロジン、変性ロジン、ロジン金属塩及びロジンエステルなどが挙げられる。  Examples of the natural resin include wood rosin, gum rosin, modified rosin, rosin metal salt, and rosin ester.

上記展着樹脂[B]のうち、特に(メタ)アクリル樹脂が好ましい。  Of the spreading resin [B], a (meth) acrylic resin is particularly preferable.

上記展着樹脂[B]のガラス転移温度は、−60℃〜+60℃が好ましく、更に好ましくは−40℃〜+40℃である。ガラス転移温度が、−60℃未満であると塗膜が軟弱で使用に耐えられず、+60℃超であると塗膜が脆く剥がれ易くなるからである。  The glass transition temperature of the spreading resin [B] is preferably −60 ° C. to + 60 ° C., more preferably −40 ° C. to + 40 ° C. This is because if the glass transition temperature is less than −60 ° C., the coating film is soft and cannot be used, and if it exceeds + 60 ° C., the coating film becomes brittle and easily peels off.

上記展着樹脂[B]の数平均分子量は、1,000〜100,000が好ましく、更に好ましくは10,000〜50,000である。数平均分子量が1,000未満であると防汚塗料組成物の粘度が上がらないため、漁網等の水中構築物への付着率が少なくなり、その結果、防汚効果が長期間持続出来なくなり、100,000超であると防汚塗料組成物の粘度が高くなり過ぎ、取り扱いが困難となるからである。
これらの展着樹脂[B]は、単独で用いてもよいし、2種以上を組み合わせて用いてもよい。
The number average molecular weight of the spreading resin [B] is preferably 1,000 to 100,000, and more preferably 10,000 to 50,000. When the number average molecular weight is less than 1,000, the viscosity of the antifouling coating composition does not increase, so the adhesion rate to underwater structures such as fishing nets decreases, and as a result, the antifouling effect cannot be sustained for a long time. This is because the viscosity of the antifouling coating composition becomes too high and the handling becomes difficult if it exceeds 1,000.
These spreading resins [B] may be used alone or in combination of two or more.

本発明の防汚塗料組成物における展着樹脂[B]の含有量は限定的ではないが、防汚塗料組成物100重量部に対して、通常1〜50重量部であり、好ましくは、5〜20重量部である。1重量部未満では、漁網等の水中構築物への付着力が弱く、長期間防汚効果を維持することが出来ない。また、50重量部超では、漁網等の水中構築物への付着力は強くなるが、展着樹脂が多すぎるため、防汚薬剤の溶出量が少なく防汚効果が悪くなってしまうからである。  The content of the spreading resin [B] in the antifouling paint composition of the present invention is not limited, but is usually 1 to 50 parts by weight, preferably 5 parts per 100 parts by weight of the antifouling paint composition. ~ 20 parts by weight. If it is less than 1 part by weight, the adhesion to an underwater structure such as a fishing net is weak, and the antifouling effect cannot be maintained for a long time. Moreover, if it exceeds 50 parts by weight, the adhesion to an underwater structure such as a fishing net will be strong, but since there are too many spreading resins, the amount of antifouling agent eluted is small and the antifouling effect will be poor.

表4〜6から明らかなように、本発明の変性シリコーンオイルを用いた実施例1〜20の防汚塗料組成物と他のシリコーンオイルを使用した比較例1〜9の防汚塗料組成物とでは、動物性汚損生物に対する防汚性能の比較で防汚効果持続時間に差があり、本発明の変性シリコーンオイルを使用した防汚塗料組成物が長期間にわたり優れた防汚効果を発揮していることがわかる。  As is clear from Tables 4-6, the antifouling paint compositions of Examples 1-20 using the modified silicone oil of the present invention and the antifouling paint compositions of Comparative Examples 1-9 using other silicone oils, Therefore, there is a difference in the antifouling effect duration in comparison of antifouling performance against animal fouling organisms, and the antifouling coating composition using the modified silicone oil of the present invention exhibits an excellent antifouling effect over a long period of time. I understand that.
