Description
【0001】
【発明の属する技術分野】
本発明は、分子内に金属カルボキシレートを有する樹脂を有効成分とする水性防汚樹脂組成物に関する。
【0002】
【従来の技術】
従来、防汚塗料のバインダーとして錫のカルボキシレートを有する樹脂が広く用いられてきたが、毒性の問題から他の樹脂系への転換が強く求められている。これに対し、主に銅や亜鉛のカルボキシレートを有する樹脂が種々検討されており、例えば、特開昭62−57464号、特開平8−209005号公報等において提案されている。これ等金属のカルボキシレートを有する樹脂は、全て溶剤希釈型であり、近年、環境保全、作業環境の改善の面から水性化が望まれていた。
一方、金属カルボキシレートを有するエマルジョンとしては、従来、フロアーポリッシュと呼ばれる床用被覆エマルジョンが知られている。該エマルジョンにおいて、金属はアミン錯体を形成しており、これを塗布・乾燥時、アミンが揮発してエマルジョンのカルボキシル基と金属によりエマルジョン粒子間を架橋し成膜するものである。しかしながら、該フロアーポリッシュを防汚塗料のバインダーとして用いても耐水性が悪く摩耗性が不良であった。
【0003】
【発明が解決しようとする課題】
本発明の目的は、金属カルボキシレートを有する樹脂を安定に水性化して有機溶剤量を大巾に削減し、しかも塗膜の溶出速度の制御を可能とし長期に渡って防汚性を発揮できる水性防汚樹脂組成物を提供することにある。

に関する。
【0005】
【発明の実施の形態】
本発明において樹脂(a)は、酸価10〜300mgKOH/gを有する基体樹脂中のカルボキシル基と2価金属との当量比が0.1〜5となるよう形成された金属カルボキシレート構造を分子内及び/又は分子間に有する樹脂であり、例えば分子内にカルボキシル基を有する基体樹脂に、2価の金属の酸化物あるいは水酸化物を、該基体樹脂固形分に対して1〜30重量%の水の存在下で反応させることによって得ることができるものである。
上記基体樹脂は、また、カルボキシル基と、さらに下記一般式(I)
一般式(I)
【化7】
(式中、R1は水素又は炭素数1〜20の直鎖、分岐又は環状のアルキル基又はアラルキル基を、mは1〜4の整数を、nは1〜100の整数をそれぞれ示す)で表わされるポリアルキレングリコール構造を有する基を有するものであってもよい。
【0006】
上記基体樹脂は、酸価10〜300mgKOH/g、好ましくは20〜200mgKOH/g、さらに好ましくは50〜150mgKOH/gを有するものである。該酸価が10mgKOH/g未満では、得られる塗膜の摩耗性が不足し、充分な防汚性が得られず、一方300mgKOH/gを越えると基体樹脂が高粘度となり取扱いが困難になるので好ましくない。
該基体樹脂としては、例えばアクリル樹脂、ポリエステル樹脂、ポリウレタン樹脂,ポリアミド樹脂等が上げられるが、特にカルボキシル基含有モノマー及びこれと共重合可能なその他のモノマーを、またはカルボキシル基含有モノマー、ポリアルキレングリコール構造を有する基を含有するモノマー及びこれ等と共重合可能なその他のモノマーを、ラジカル重合開始剤の存在下に溶液重合法等の常法によって共重合させることによって得られるアクリル重合体が好適である。
【0007】
上記カルボキシル基含有モノマーとしては、例えば(メタ)アクリル酸、クロトン酸、イタコン酸、マレイン酸、フマル酸等が挙げられる。
上記ポリアルキレングリコール構造を有する基を含有するモノマーとしては、例えばメトキシエチル(メタ)アクリレート、ヒドロキシエチル(メタ)アクリレート、メトキシポリエチレングリコール(メタ)アクリレート、ノニルフェノキシポリエチレングリコール(メタ)アクリレート、メトキシポリプロピレングリコール(メタ)アクリレート等が挙げられる。
これ等と共重合可能なその他のモノマーとしては、例えばスチレン、α−メチルスチレン、ビニルトルエン、α−クロルスチレン等のビニル芳香族化合物;メチル(メタ)アクリレート、エチル(メタ)アクリレート、n−プロピル(メタ)アクリレート、i−プロピル(メタ)アクリレート、(n−、i−、t−)ブチル(メタ)アクリレート、ヘキシル(メタ)アクリレート、シクロヘキシル(メタ)アクリレート、2−エチルヘキシル(メタ)アクリレート、n−オクチル(メタ)アクリレート、デシル(メタ)アクリレート、ラウリル(メタ)アクリレート、ステアリル(メタ)アクリレート、イソボルニル(メタ)アクリレート等のアクリル酸またはメタクリル酸の炭素数1〜24個のアルキルエステルまたはシクロアルキルエステル;パーフルオロブチルエチル(メタ)アクリレート、パーフルオロイソノニルエチル(メタ)アクリレート、パーフルオロオクチルエチル(メタ)アクリレート等のパーフルオロアルキル(メタ)アクリレート、フルオロオレフィン等が挙げられ、さらにこれ等のモノマーの1種及び/またはそれ以上のモノマーの重合体で、片末端に重合性不飽和基を有する、いわゆるマクロモノマーも共重合可能なモノマーとして挙げられる。
上記モノマー混合物の溶液重合時に用いる溶媒として、例えばベンゼン、トルエン、キシレン等のアルキルベンゼン誘導体;酢酸エチル、酢酸プロピル、酢酸ブチル、酢酸アミル、酢酸メトキシブチル、アセト酢酸メチル、アセト酢酸エチル、酢酸メチルセロソルブ、セロソルブアセテート、酢酸ジエチレングリコールモノメチルエーテル、酢酸カルビトール等の酢酸エステル系溶剤;ジオキサン、エチレングリコールジエチルエーテル、エチレングリコールジブチルエーテル、ジエチレングリコールジエチルエーテル等のエーテル系溶剤;メタノール、エタノール、プロパノール、i−プロパノール、(n−、i−、t−)ブタノール等のアルコール系溶剤;アセトン、メチルエチルケトン、メチルイソブチルケトン、シクロヘキサノン等のケトン系溶剤が挙げられ、これ等は単独でまたは2種以上混合して使用できる。
ラジカル重合開始剤としては、例えば過酸化ベンゾイル、ジ−t−ブチルハイドロパーオキサイド、t−ブチルハイドロパーオキサイド、クミルパーオキサイド、クメンハイドロパーオキサイド、ジイソプロピルベンゼンハイドロパーオキサイド、t−ブチルハイドロパーオキシベンゾエート、ラウリルパーオキサイド、アセチルパーオキサイド、t−ブチルハイドロパーオキシ−2−エチルヘキサノエート等の過酸化物;α、α′−アゾビスイソブチロニトリル、α、α′−アゾビス−2−メチルブチロニトリル、アゾビスジメチルバレロニトリル、アゾビスシクロヘキサンカルボニトリル等のアゾ化合物が挙げられる。
【0008】
上記の通り得られる基体樹脂の数平均分子量は、通常、1,000〜200,000、好ましくは2,000〜100,000、さらに好ましくは2,000〜50,000の範囲内である。該数平均分子量が1,000未満では、乾燥性が不充分となり塗膜の耐候性、耐久性が低下し、一方200,000より大きいと仕上がり外観が低下するだけでなく塗膜の摩耗性が不足し、充分な防汚性が得られないので好ましくない。
また上記基体樹脂がポリアルキレングリコール構造を有する基を有する場合には、該アルキレングリコール単位が上記基体樹脂100g中に0.005モル以上含まれることが、摩耗性向上の点から好適である。
【0009】
本発明で使用する樹脂(a)は、例えば、上記の通り得られる基体樹脂に、2価の金属の酸化物あるいは水酸化物を、該基体樹脂固形分に対して1〜30重量%の水の存在下で、通常、50〜200℃で1〜20時間反応させることによって得ることができる。反応初期には、粉末状の金属化合物が基体樹脂中に分散しているだけであるが、反応の進行とともに全体が透明になる。該反応系には適当量の極性溶剤を添加することもできる。該極性溶剤としては、例えばアルコール系、ケトン系、エスデル系、エーテル系溶剤等が挙げられる。
上記2価金属の酸化物あるいは水酸化物としては、特に制限なく使用できるが、コスト、毒性、反応性等の点から銅、亜鉛、カルシウム、マグネシウム、鉄のいずれかの酸化物あるいは水酸化物が好ましい。
この工程において、水は反応を促進させる効果と同時に、ゲル化を防止する効果も有するが、1重量%未満ではその効果がみられず、30重量%を越えて用いてもその効果は変わらない。反応終了後に、系に溶解しない過剰の水分は、減圧、デカンテーション、加熱等の方法により容易に除去できる。
【0010】
ここでは基体樹脂中のカルボキシル基と金属化合物の配合比は、モル比でカルボキシル基/金属化合物=0.1〜5.0の範囲内にあることが好ましい。該モル比が0.1より小さいと反応に長時間要するようになり、実用的でなく、一方モル比が5.0より大きくなると有効成分である金属カルボキシレート構造よりもフリーのカルボン酸の方が多くなり、経時で摩耗性を発揮することが困難になるので好ましくない。
上記の通り得られる樹脂(a)は、基体樹脂中のカルボキシル基と2価金属との当量比(COO−/M2+)が0.1〜5、好ましくは0.25〜2となるよう金属カルボキシレート構造を分子内及び/または分子間に形成せしめてなるものである。
【0011】
本発明の樹脂組成物は、上記の通り得られる樹脂(a)から選ばれる少なくとも1種を、乳化剤(b)を用いて水分散してなる水性樹脂エマルジョン(A)を有効成分として含有する。
該乳化剤(b)としては、従来公知の界面活性剤が使用可能であり、好適には、下記一般式(II)または(III)
一般式(II)
【化8】
一般式(III)
【化9】

If the acid value is less than 10 mg KOH / g, the resulting coating film has insufficient wear properties and sufficient antifouling properties cannot be obtained. On the other hand, if it exceeds 300 mg KOH / g, the base resin has a high viscosity and is difficult to handle. It is not preferable.

[0008]
The number average molecular weight of the base resin obtained as described above is usually in the range of 1,000 to 200,000, preferably 2,000 to 100,000, and more preferably 2,000 to 50,000. When the number average molecular weight is less than 1,000, the drying property is insufficient, and the weather resistance and durability of the coating film are deteriorated. On the other hand, when the number average molecular weight is more than 200,000, not only the finished appearance is deteriorated but also the wear property of the coating film is deteriorated. Insufficient antifouling property is not obtained, which is not preferable.
In addition, when the base resin has a group having a polyalkylene glycol structure, it is preferable from the viewpoint of improving wear resistance that the alkylene glycol unit is contained in an amount of 0.005 mol or more in 100 g of the base resin.
[0009]
The resin (a) used in the present invention is, for example, a base resin obtained as described above containing a divalent metal oxide or hydroxide in an amount of 1 to 30% by weight of water based on the solid content of the base resin. In the presence of, usually at 50 to 200 ° C. for 1 to 20 hours. At the beginning of the reaction, the powdered metal compound is only dispersed in the base resin, but the whole becomes transparent as the reaction proceeds. An appropriate amount of a polar solvent can be added to the reaction system. Examples of the polar solvent include alcohol-based, ketone-based, esdel-based, and ether-based solvents.
The divalent metal oxide or hydroxide can be used without any particular limitation, but it is any oxide or hydroxide of copper, zinc, calcium, magnesium, iron from the viewpoint of cost, toxicity, reactivity, etc. Is preferred.
In this step, water has the effect of promoting the reaction and the effect of preventing gelation, but the effect is not seen when it is less than 1% by weight, and the effect is not changed even if it is used in excess of 30% by weight. . After the reaction is completed, excess water that does not dissolve in the system can be easily removed by methods such as reduced pressure, decantation, and heating.
[0010]
Here, the mixing ratio of the carboxyl group and the metal compound in the base resin is preferably in the range of carboxyl group / metal compound = 0.1 to 5.0 in terms of molar ratio. If the molar ratio is less than 0.1, the reaction takes a long time and is not practical. On the other hand, if the molar ratio is larger than 5.0, the free carboxylic acid is more active than the metal carboxylate structure as the active ingredient. This is not preferable because it becomes difficult to exhibit wear characteristics over time.
The resin (a) obtained as described above is a metal so that the equivalent ratio (COO − / M 2+ ) between the carboxyl group and the divalent metal in the base resin is 0.1 to 5, preferably 0.25 to 2. A carboxylate structure is formed in and / or between molecules.
[0011]
The resin composition of the present invention contains, as an active ingredient, an aqueous resin emulsion (A) obtained by water-dispersing at least one selected from the resin (a) obtained as described above using an emulsifier (b).
As the emulsifier (b), a conventionally known surfactant can be used, and preferably the following general formula (II) or (III)
Formula (II)
[Chemical 8]
Formula (III)
[Chemical 9]

Product), “Eleminol ES70” (manufactured by Sanyo Chemical Co., Ltd.), “Hitenol N # 17” (manufactured by Daiichi Kogyo Seiyaku Co., Ltd.), and the like.
The emulsifier (b) is added in an amount of 2 to 20 parts by weight, preferably 5 to 10 parts by weight, based on 100 parts by weight of the solid content of the resin (a). If the amount added is less than 2 parts by weight, a uniform and stable emulsion cannot be obtained. On the other hand, if it exceeds 20 parts by weight, the resulting coating film tends to swell and the water resistance is remarkably lowered.
[0012]
The resin emulsion (A) is produced by mixing the resin (a) and the emulsifier (b), gradually increasing the stirring speed, and dropping water under stirring to disperse in water. The resin emulsion (A) thus obtained is a stable emulsion having a particle size of 400 nm or less.
When emulsifying the resin (a), the resin (a) is mixed with other resin or antifouling agent as necessary, and then dispersed in water in the same manner as above to produce a resin emulsion (A). May be. As such other resin, for example, rosin or the like can be used from the viewpoint of wear control, and it can be added in an amount of 50 parts by weight or less, preferably 1 to 20 parts by weight based on 100 parts by weight of the resin (a). . As the antifouling agent, for example, “Sine Nine 211” (made by Rohm & Haas, isothiazoline-based compound) that is soluble in a solvent can be used from the viewpoint of imparting antifouling properties, and the resin (a) is 100 parts by weight in solid content. 20 parts by weight or less, preferably 1 to 10 parts by weight can be added.
[0013]
In the emulsion (A), another resin emulsion may be used in combination as necessary. As other resin emulsions, conventionally known emulsions can be used without particular limitation. For example, low acid number emulsions such as acrylic emulsion, acrylic-styrene emulsion, vinyl acetate emulsion, ethylene-vinyl acetate emulsion, and floor polish emulsion “AE175”. Examples thereof include high acid value emulsions containing zinc ammonia complex salts such as (manufactured by Nippon Synthetic Rubber). These can be added in a solid content of 50 parts by weight or less, preferably 1 to 20 parts by weight, based on 100 parts by weight of the resin (a). If the amount added exceeds 50 parts by weight, the wear resistance of the resulting antifouling coating film is lowered, which is not desirable.
[0014]
The antifouling paint composition of the present invention includes those containing the resin emulsion (A) and the antifouling agent (B).
Examples of the antifouling agent include copper antifouling agents such as galvanized copper, thiocyanic copper and copper powder; nitrogen-containing sulfur antifouling agents such as ethylenebis (dithiocarbamate) zinc and tetramethylthiuram disulfide; Organotin series such as bis (triphenyltin) oxide, bis (tributyltin) oxide, tributyltin acetate, tributyltin chloride, triphenyltin hydroxide, triphenyltin versatate, bis (tributyltin) α, α'-dibromosuccinate Antifouling agents: nitrile compounds, benzothiazole compounds, triazine compounds, urea compounds, isothiazoline compounds, maleimide compounds, N-haloalkylthio compounds, tetracycline compounds, zinc pyrithione, triphenylboron pyridine salts, etc. And bactericides such as zinc compounds and zinc oxide.
The amount of the antifouling agent is suitably about 100 to 300 parts by weight with respect to 100 parts by weight of the resin solid content.
In the case of the antifouling agent powder, the resin emulsion (A) can be mixed with stirring as it is, but it is usually appropriate to add the antifouling agent as a paste using a dispersant and water. From the standpoint of stability, the resin emulsion (A) can be appropriately added to the antifouling agent and water paste and pre-kneaded.
[0015]
The antifouling paint composition of the present invention may further contain pigments, plasticizers, solvents, and other usual additives used in antifouling paints and water-based paints, if necessary.
The method of forming a coating film using the coating composition of the present invention is not particularly limited, and conventionally known methods are used. Specifically, it is directly on the surface of a substrate such as an underwater structure (for example, a ship, a port facility, a buoy, a pipeline, a bridge, a submarine base, an aquaculture net, a stationary net, etc.), or a wash primer or zinc epoxy system on the substrate.

【The invention's effect】
According to the present invention, a resin having a metal carboxylate can be stably made water-based, the amount of organic solvent can be greatly reduced, and the coating film of the present invention aqueous antifouling resin composition can be eluted in the same manner as a solvent diluent. The speed can be controlled and the antifouling property can be exhibited for a long time. In the present invention, the antifouling property can be exhibited over a long period of time when the aqueous resin emulsion as a binder has a metal carboxylate in the emulsion particles, and the emulsion particles are fused to form a film. Because it is. Therefore, the obtained coating film has excellent water resistance, and when the coating film comes into contact with seawater, the metal carboxylate portion in the particles only on the coating film surface is solubilized and eluted.
