Description

本発明は、水系防汚塗料組成物該水系防汚塗料組成物を塗布されてなる漁網等の漁具および該水系防汚塗料組成物を用いる漁網等の漁具の防汚方法に関する。さらに詳しくは、本発明は、従来の有機溶剤型防汚塗料と比較して防汚性に優れるうえ、揮発性の高い有機溶剤を多く含まないため環境や作業者に与える影響が極めて少なく、凍結融解安定性など貯蔵安定性に優れ、また低温における造膜性や付着性能にも優れ、長期に安定した防汚性能を発揮する水系防汚塗料組成物、該水系防汚塗料組成物を塗布させてなる漁網および該水系防汚塗料組成物を用いる漁網の防汚方法に関する。   The present invention relates to a water-based antifouling paint composition, a fishing tool such as a fishing net to which the water-based antifouling paint composition is applied, and a method for antifouling a fishing tool such as a fishing net using the water-based antifouling paint composition. More specifically, the present invention is superior in antifouling properties as compared with conventional organic solvent-type antifouling paints, and does not contain a large amount of highly volatile organic solvents, so it has very little impact on the environment and workers, and is freezing. A water-based antifouling paint composition that is excellent in storage stability such as melting stability, and has excellent film-forming properties and adhesion performance at low temperatures and exhibits stable antifouling performance over a long period of time. And a fishing net antifouling method using the water-based antifouling paint composition.

船舶や海洋構造物、養殖用または定置用の漁網などは海中に長期保存させるために、珪藻類、アオサ、アオノリ、イギスなどの海藻類、ヒドロ虫、フジツボ、セルプラ、コケムシ、軟体動物類などの海棲汚損生物の付着が激しく、その結果、本来の機能が損なわれることがある。さらに海棲動植物の他にそれらの生物の***物、死骸などの有機汚物およびいわゆるスライムなどの付着によっても機能が損なわれることがある。例えば船舶などでは、前述海棲生物の付着により海水中での摩擦抵抗が増加し燃費が増加する。また発電所では、冷却水として海水を用いる際、生物が付着することによって熱交換を著しく阻害する。また漁網の場合、養殖網や定置網などに付着生物が付着すると網が重くなり、沈下により魚が逃げ、また、網自体が流失する恐れがある。そのため頻繁に取替えを要することが多く、それらの保守に多大の労力と費用をかけているのが現状である。   Ships, marine structures, aquaculture or stationary fishing nets are stored in the sea for a long time. Ridge-fouling organisms are heavily attached, and as a result, their original functions may be impaired. In addition to marine plants and animals, the function may be impaired by the attachment of excrement of such organisms, organic filth such as dead bodies, and so-called slime. For example, in a ship or the like, frictional resistance in seawater increases due to adhesion of the marine organisms, and fuel consumption increases. Moreover, in a power plant, when seawater is used as cooling water, heat exchange is remarkably inhibited by the attachment of living organisms. In the case of fishing nets, if attached organisms adhere to aquaculture nets or stationary nets, the nets become heavier, fish may escape due to settlement, and the nets themselves may be washed away. Therefore, frequent replacement is often required, and the present situation is that much labor and cost are spent on the maintenance.

従来からこれらの海棲生物の付着を防止する目的で有機錫化合物を主成分とする防汚塗料が広く使用されてきた。しかしながら、その毒性の強さから環境に与える影響も大きいため、有機錫化合物含有の防汚塗料はその使用が制限されている。その後、この有機錫化合物に代わるものとして様々な低毒性の海棲生物忌避剤を用いた防汚塗料が開発され、使用されている。   Conventionally, antifouling paints based on organotin compounds have been widely used for the purpose of preventing adhesion of these marine organisms. However, the use of organic tin compound-containing antifouling paints is limited because of its strong toxicity and large impact on the environment. Since then, antifouling paints using various low-toxic marine organism repellents have been developed and used as an alternative to the organotin compounds.

しかしながら、これらの防汚塗料は、現在あるもののほとんどが芳香族系溶剤を主とする有機溶剤を溶媒として用いて来た。そのため近隣住民への影響、さらには温暖化など地球規模の環境に与える影響も懸念されている。こういった問題を解決すべく、種々の水系防汚塗料が提案されている。   However, most of these antifouling paints currently use an organic solvent mainly composed of an aromatic solvent as a solvent. For this reason, there are concerns about the impact on neighboring residents and the impact on the global environment such as global warming. In order to solve such problems, various water-based antifouling paints have been proposed.

例えば、特許文献1乃至4等には水系防汚塗料が提案されているが、いずれも要求される防汚性能を満たしているとは言いがたい。   For example, Patent Documents 1 to 4 propose water-based antifouling paints, but it is difficult to say that all satisfy the required antifouling performance.

特許文献5では、アクリル樹脂エマルジョン等の水系ポリマーエマルジョンをバインダーとして含有し、海棲生物忌避剤として効果の高いピリジン−トリフェニルボラン、ピリチオン金属塩、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、チオカーバメート化合物を微粒分散化した水系防汚塗料組成物が提案されているが、微粒分散化に多大な労力をかけねばならず、また微粒子化による粘度上昇などの貯蔵安定性やこれら海棲生物忌避剤の早期溶出による長期防汚性に問題がある。また、これらの水系防汚塗膜を形成するためには、配合されているバインダー構成成分の造膜温度以上で乾燥させるか、造膜助剤として高沸点溶剤を配合させる必要がある。造膜温度の低いバインダーとして上記の特許では、ガラス転移点の低い水系ポリマーエマルションを用いているが、形成塗膜が柔らかく、タックや塗膜流出など実際の使用には問題が残る。造膜温度の高いバインダーを用い、造膜助剤として高沸点溶剤を配合した場合、水系防汚塗料としての安全性が得られないだけでなく、従来の使用方法では、高沸点溶剤が揮発するまでに時間を要するなど、乾燥設備等がない場合には有効な防汚効果が発揮できるための塗膜を得ることが出来ない。また、いずれの場合も従来のエマルジョン型防汚塗料の欠点として、凍結した場合は解凍後に樹脂分が分離または凝集する所謂凍結融解安定性などの貯蔵安定性が極端に悪いことから、寒冷地などでの使用に耐え得るものではない。   In Patent Document 5, pyridine-triphenylborane, pyrithione metal salt, bisdimethyldithiocarbamoyl zinc ethylene bisdithiocarbamate, thiocarbamate, which contains an aqueous polymer emulsion such as an acrylic resin emulsion as a binder and is highly effective as a marine organism repellent. Water-based antifouling paint compositions in which compounds are finely dispersed have been proposed. However, great efforts must be made to disperse fine particles, and storage stability such as increase in viscosity due to the formation of fine particles and these marine organism repellents. There is a problem in the long-term antifouling property due to early elution of. In addition, in order to form these water-based antifouling coating films, it is necessary to dry the film at a temperature equal to or higher than the film forming temperature of the blended binder component, or to add a high boiling point solvent as a film forming aid. In the above patent, a water-based polymer emulsion having a low glass transition point is used as a binder having a low film forming temperature, but the formed coating film is soft, and problems remain in actual use such as tack and coating film outflow. When a binder with a high film-forming temperature is used and a high-boiling solvent is blended as a film-forming auxiliary, not only the safety as a water-based antifouling paint can be obtained, but the high-boiling solvent volatilizes in the conventional method of use. If there is no drying equipment or the like, it is not possible to obtain a coating film that can exhibit an effective antifouling effect. In either case, the disadvantage of the conventional emulsion type antifouling paint is that the storage stability such as so-called freeze-thaw stability in which the resin component separates or aggregates after thawing when frozen is extremely poor. It cannot withstand use in

特許文献6では、バインダーにポリブテンのエマルジョンを含むことで低温造膜性と貯蔵安定性を改善した水性防汚塗料組成物が提案されている。しかしながら、ポリブテンを含むだけでは被塗物に対する付着性が十分でなく、また形成塗膜の柔軟性が得られないため、特に漁網のような被塗物上で防汚塗膜を維持することが出来ず、長期防汚に耐え得る防汚塗膜を得ることは出来ていない。

Patent Document 6 proposes an aqueous antifouling paint composition having improved low-temperature film-forming properties and storage stability by containing a polybutene emulsion in a binder. However, only including polybutene does not provide sufficient adherence to the object to be coated, and the flexibility of the formed film cannot be obtained. An antifouling coating film that cannot withstand long-term antifouling cannot be obtained.

以上の水系防汚塗料を実際に塗装する場合、最も大きな問題点は、乾燥性である。水は有機溶剤などと比べて乾燥が遅く、乾きにくい欠点を有している。また、水系防汚剤を完全に乾燥せずに海に展開した場合、塗膜が海水中に溶け出して、効果が失われてしまうばかりか、海洋環境を汚染してしまう。
なぜ、漁網に塗布する防汚塗料の場合、乾燥性が問題になるかを以下に説明する。
When the above water-based antifouling paint is actually applied, the biggest problem is dryness. Water has a drawback that it is slower to dry than organic solvents and is difficult to dry. In addition, when the water-based antifouling agent is deployed in the sea without being completely dried, the coating film dissolves in the seawater and the effect is lost, and the marine environment is contaminated.
The reason why dryness becomes a problem in the case of antifouling paints applied to fishing nets will be described below.

漁網や、漁網具に防汚塗料を塗装する場合、スプレー塗装やハケ塗ではなく、一般に浸漬塗装が行われる。スプレー塗装やハケヌリでは、網を広げたり、表裏両面を塗装する必要があり大変手間が掛かる。また、塗着効率(塗着した塗料/塗装に要した塗料)が極端に悪く、塗装に要する塗料の多くがミストなどで消えてしまう。   When an antifouling paint is applied to a fishing net or fishing net equipment, dip coating is generally performed instead of spray coating or brush coating. In spray painting and hakenuri, it is necessary to spread the net or paint both sides, which is very time consuming. In addition, the coating efficiency (paint applied / paint required for painting) is extremely poor, and most of the paint required for painting disappears due to mist.

そこで、網をコンパクトに折りたたみ、塗料溶液の中に網を浸漬することによって、ムラなく楽に、また塗着効率もよく塗装することが出来る。塗装後、乾燥は網を広げて行うことが好ましいが、定置網や、養殖網など、大型の網の場合、場所的に広げて長期間乾燥することは困難で、折りたたんだまま乾燥させている。従来の溶剤型防汚塗料の場合、折りたたまれた状態でもある程度乾燥し、なかんずく乾燥が不十分であっても塗膜が海水中に溶け出ることはなかった。   Therefore, by folding the net compactly and immersing the net in the coating solution, it is possible to apply the coating comfortably and with good coating efficiency. After painting, drying is preferably performed by spreading the net. However, in the case of a large net such as a stationary net or an aquaculture net, it is difficult to spread it for a long time and to dry for a long time, and it is dried while folded. In the case of a conventional solvent-type antifouling paint, it dries to some extent even in a folded state, and the coating film does not dissolve in seawater even if the drying is insufficient.

ところが、上記のような水系漁網防汚剤の場合、溶剤型に比べて乾燥が悪くまた、乾燥が不十分なまま海水中で使用された場合塗膜が海水中に溶け込み効果が失われてしまう。そのため、従来の有機溶剤型防汚塗料に比べてより充分に乾燥する必要があり、乾燥に要する手間が極端に掛かる結果となっている。   However, in the case of the water-based fishing net antifouling agent as described above, the drying effect is poor compared to the solvent type, and when used in seawater with insufficient drying, the coating effect is lost in seawater. . Therefore, it is necessary to dry more sufficiently than the conventional organic solvent-type antifouling paint, resulting in extremely troublesome work for drying.

以上のようにこれまでの水系防汚塗料では、従来の有機溶剤型防汚塗料の代替品として使用に耐え得るものはなかった。   As described above, none of the conventional water-based antifouling paints can withstand use as a substitute for conventional organic solvent-type antifouling paints.

従って、本発明の目的は、従来の有機溶剤型防汚塗料と比較して、防汚性に優れるうえ、揮発性の高い有機溶剤を多く含まないため環境や作業者に与える影響が少なく、凍結融解安定性など貯蔵安定性に優れ、また低温における造膜性や付着性能にも優れた、長期に安定した防汚性能を発揮する防汚塗膜を形成する水系防汚塗料組成物、魚網用水系防汚塗料組成物、該魚編みよう水系防汚塗料組成物を施工した漁網及び該魚網用水系防汚塗料組成物を施工する方法を提供することにある。   Accordingly, the object of the present invention is superior in antifouling properties compared to conventional organic solvent type antifouling paints, and has little influence on the environment and workers because it does not contain a lot of highly volatile organic solvents. Water-based antifouling paint composition that forms an antifouling coating that exhibits stable antifouling performance over a long period of time, with excellent storage stability such as melting stability, and excellent film-forming properties and adhesion performance at low temperatures, and water for fishnets An object of the present invention is to provide a water-based antifouling paint composition, a fishing net on which the fish knitting water-based antifouling paint composition is applied, and a method for applying the water-based antifouling paint composition for fishnets.
