Definitions
- the present invention relates to a sustained-release bactericidal and antibacterial agent for a cationic electrodeposition coating system that does not adversely affect the cationic electrodeposition and the physical properties of the coating film and is easy to replenish.
- This application claims priority based on Japanese Patent Application No. 2008-283366 for which it applied to Japan on November 4, 2008, and uses the content here.
- Cationic electrodeposition paints are excellent in throwing power (the ability to form a coating even in places where the paint is difficult to attach, such as objects with a bag structure), and have excellent durability and corrosion resistance. Therefore, it is widely used as an undercoating paint for conductive metals such as automobile bodies and electrical products.
- the cationic electrodeposition paint is a non-aqueous (solvent) system
- the organic solvent in the electrodeposition bath serves as a preservative and no preservative is required.
- a paint used for cationic electrodeposition coatings As a paint used for cationic electrodeposition coatings, basic resins (for example, amine-modified epoxy resins) are neutralized with neutralizing organic acids (for example, sulfamic acid, acetic acid, dimethylolpropionic acid, formic acid, and lactic acid). However, water-soluble or emulsified ones are used. When cationic electrodeposition is performed, neutralizing acid ions are generated near the anode. It is known that electrodeposition is promoted by removing neutralized acid ions of a certain concentration or more accumulated in the electrodeposition tank.
- neutralizing organic acids for example, sulfamic acid, acetic acid, dimethylolpropionic acid, formic acid, and lactic acid.
- water-soluble or emulsified ones are used.
- excessive neutralized acid ions are selectively introduced into the diaphragm chamber through a diaphragm made of an ion exchange membrane, and this diaphragm solution (polar solution) containing excess neutralized acid ions, etc. is sent to the polar liquid tank, A predetermined process is performed, and a part is returned to the electrodeposition tank.
- polar solution polar solution
- microorganisms such as fungi and bacteria are likely to propagate. Due to the propagation of bacteria and the like, problems such as the difficulty of forming an electrodeposited film, peeling of the formed film, poor appearance and poor corrosion resistance, etc. have occurred.

- the object to be coated with the electrodeposition coating is then taken out of the tank from the electrodeposition tank by the conveyor, but a slight amount of electrodeposition coating liquid is adhered to the surface of the object to be coated. Therefore, a water-washing process is performed on the object to be coated in order to remove the electrodeposition coating liquid.
- a water-washing process is performed on the object to be coated in order to remove the electrodeposition coating liquid.
- an object to be coated with electrodeposition is washed with water by a dip water washing device, spray water washing device, industrial water spray washing device, ion exchange water spray washing device, etc. while being conveyed by a conveyor, and adheres to the surface.
- the electrodeposition coating liquid is removed.
- the dip rinsing apparatus or the rinsing apparatus is washed with the rinsing water stored (held) in the dip rinsing tank or the rinsing water reservoir.
- Microorganisms such as fungi and bacteria are likely to propagate in the wash water thus stored. These microorganisms mainly live as a group on the inner wall of the dip water washing tank or washing water storage tank, and some of these film-like deposits (slims) often peel off from the inner wall. As a result, it becomes a floc floating in the washing water. Such flocs tend to adhere to or adhere to the coating film of the electrodeposited object.
- the floc adheres to the coating film of the object to be coated, Even if it is washed with a spray washing device or an ion-exchange water spray washing device, it is not easily removed, and it may be brought into the next coating process as it is to cause a defective coating film.

(8)前記通水性容器が不織布で形成されている前記(6)に記載のカチオン電着塗装システム用徐放性殺菌・抗菌剤、
(9)前記(1)~(8)に記載の徐放性殺菌・抗菌剤を、カチオン電着塗装システムにおけるカチオン電着塗料中に浸しまたはカチオン電着塗料の流通下に置き、1,2-ベンゾイソチアゾリン-3-オンがカチオン電着塗料に徐々に溶解するようにしたカチオン電着塗料の殺菌・抗菌方法、
(10)前記(1)~(8)に記載の徐放性殺菌・抗菌剤を、カチオン電着塗装システムにおける極液中に浸しまたは極液の流通下に置き、1,2-ベンゾイソチアゾリン-3-オンが極液に徐々に溶解するようにした極液の殺菌・抗菌方法、および
(11)前記(1)~(8)に記載の徐放性殺菌・抗菌剤を、カチオン電着塗装システムにおける洗浄水中に浸しまたは洗浄水の流通下に置き、1,2-ベンゾイソチアゾリン-3-オンが洗浄水に徐々に溶解するようにした洗浄水の殺菌・抗菌方法、である。
本発明のカチオン電着塗装システム用徐放性殺菌・抗菌剤は、主成分として、1,2-ベンゾイソチアゾリン-3-オン(以下、「BIT」と記載することがある。)を含有するものである。BITは、粉末状または顆粒状の各種製品が市販されており、それらを使用することができる。また、BITをゲストとし、該ゲストをホストで取り囲むことによって生じるBIT包接化合物を使用することができる。
配合できる成分は特に制限されない。例えば、流動剤、賦形剤、滑沢剤、結合剤、BIT以外の防腐・抗菌剤、pH調整剤、キレート剤、消泡剤などが挙げられる。徐放性を高めるために、配合成分として溶解性の異なる基材などを使い、一定時間持続的に有効成分が放出されるよう調整することができる。例えば、タブレットまたはブリケットの表面に皮膜などを施すなどして、徐放性を高めることができる。
流動剤としては、例えば、ステアリン酸などの長鎖脂肪酸;長鎖(炭素数10~22個)脂肪酸のモノグリセリド、ジグリセリド、トリグリセリド;カルナバロウ、ポリオキシエチレン硬化ヒマシ油、ステアリルアルコール等の高級脂肪アルコール;セタノールなどのワックス;レシチン、ラウリル硫酸ナトリウムを挙げることができる。流動剤は、本発明錠剤中に、例えば5%質量%以下で含有させることができる。
具体的には、BITに賦形剤などの配合成分を適宜加えて練り合わせ、のばしたものを一定の形に打ち抜いて製造する湿製方法;混合した原料を圧縮形成する方法;湿式練合したものを型に入れ乾燥させる製法がある。錠剤の圧縮形成のことを「打錠」といい、本発明の徐放性殺菌・抗菌剤の製法として好ましい。打錠には、混合した原料をそのまま打錠する直接打錠法と、混合した原料を顆粒にしてから打錠する造粒打錠法がある。直接打錠法では工程は単純になるが、原料の流動性が悪いと重量にばらつきが出たり仕上がりが悪くなることがある。また、湿式練合したものを型に入れ乾燥させる製法がある。
過熱によって溶融する成分を錠剤成分として多く含ませる場合には、各成分を混ぜ合わせ、次いでそれを加熱撹拌してスラリーにし、そのスラリーを型に注入し、冷却し、型から取り出すという方法で、錠剤を成形することができる。
また、杵への付着を防止するために、主成分を含む混合物の上下に打錠性の良好な組成物を薄く層状になるように金型に充填し、しかる後に打錠して、三層構造の錠剤にする方法が好ましく採用できる。
電着塗装システムは、通常、前処理工程、電着工程および焼付乾燥工程とからなる。前処理工程は、被塗物の表面を塗装に適した状態に調整する工程である。該工程では、脱脂、水洗浄、湯洗、化成被膜などの操作が行われる。水洗浄は、通常、常温で行われ、脱脂、湯洗および化成被膜は、通常、40~60℃で行われる。電着工程は、被塗物の表面に塗膜を載せる工程である。該工程では、通常、被塗物に電気化学的に塗膜を形成させる電着塗装、未電着塗料等を洗い落とすための水洗浄(工水洗浄と純水洗浄)などの操作が行われる。電着塗装は、通常、25~35℃で行われ、水洗浄は、通常、常温で行われる。水洗浄にはスプレー洗浄、ディップ洗浄などがある。また、水洗浄は、再生水を用いる洗浄と、工水やイオン交換水などの純水を用いる仕上げ洗浄とがある。焼付乾燥工程は、被塗物の表面の塗膜を硬化させる工程である。該工程では、セッティング自然乾燥、焼付乾燥などの操作が行われる。焼付乾燥は塗料の種類に応じて温度等が選択されるが、通常、150~200℃で行われる。
カチオン電着塗料の殺菌・抗菌は、本発明の徐放性殺菌・抗菌剤をカチオン電着塗装システムの電着槽や電着塗料貯槽等に入れ、カチオン電着塗料中に浸しまたはカチオン電着塗料の流通下に置き、1,2-ベンゾイソチアゾリン-3-オンが徐々に溶解するようにして行われる。図1に示すように、電着槽は、カチオン電着塗料を満たした浴槽である。カチオン電着塗料に負極に接続された被塗物100と正極に接続された電極101とが浸され、両極間に電圧を印加することによって、塗料粒子が被塗物側に移動し、被塗物表面に塗料が載せられる。電極101側に向かって中和酸イオンが移動し、隔膜16の中に高濃度の中和酸イオンを含む極液が溜まる。電着塗料貯槽(図示せず)は、電着槽へ補充するために新たに調製された塗料や電着槽から抜き出され再生された塗料を一時的に貯蔵するための容器である。電着塗装では、カチオン電着塗料の補給だけでは、水分の蒸発や酸の極液としての持ち出し等で電着浴の液面が下がるので、イオン交換水と新鮮な中和酸または後述するように極液を電着槽に補給することができる。
また、本発明の徐放性殺菌・抗菌剤はネット等に収納して、カチオン電着塗料、極液もしくは洗浄水中に浸しまたはカチオン電着塗料、極液もしくは洗浄水の流通下に置くことができる。
(実施例1)
1,2-ベンゾイソチアゾリン-3-オン(BIT)の粉末を打錠圧900~1000kg/cm2で打錠成形して、直径30mm、質量15gの円柱状の殺菌・抗菌剤(錠剤)を得た。この殺菌・抗菌剤では、錠剤表面からBITが順次水に溶解していくので、電着槽、極液貯槽、水洗槽等内に溶け切れなかったBITが固形粉末として拡散しにくく、塗膜に支障をきたすおそれが低減されていた。
BIT 50質量部、および安息香酸 50質量部の混合物を打錠圧600~700kg/cm2で打錠成形して、直径60mm、質量60gの円板状の殺菌・抗菌剤(錠剤)を得た。この殺菌・抗菌剤では、錠剤表面からBITが順次水に溶解していくので、電着槽、極液貯槽、水洗槽等内に溶け切れなかったBITが固形粉末として拡散しにくく、塗膜に支障をきたすおそれが低減されていた。
BIT 99質量部、および蔗糖脂肪酸エステル 1質量部の混合物を打錠圧300~400kg/cm2で打錠成形して、直径30mm、質量20gの円柱状の錠剤を得た。この錠剤1錠を不織布製の袋に収納し、ヒートシールにより密封し、殺菌・抗菌剤(バッグ)を得た。この殺菌・抗菌剤では、水に不溶な蔗糖脂肪酸エステル等が電着槽、極液貯槽、水洗槽等内に拡散しないので、塗膜に支障をきたすおそれが大幅に低減されていた。
BITの粉末40gを、不織布と直径5mmの穴を5mm間隔で有する厚さ0.1mmのポリエチレンフィルムとをラミネートしてなる2層構造のフィルムからなる袋に収納し、ヒートシールにより密封し、殺菌・抗菌剤(バッグ)を得た。この殺菌・抗菌剤では、BITの固形粉末が、電着槽、極液貯槽、水洗槽等内に拡散しないので、塗膜に支障をきたすおそれが大幅に低減されていた。
実施例1~4の電着塗装システム用徐放性殺菌・抗菌剤をプラスチック製のネットに収納し、極液貯槽およびディップ水洗槽中に設置し、極液および洗浄水の流通下に置いて、通常の電着塗装の操作を連日行った。電着槽中のカチオン電着塗料およびディップ水洗槽中の洗浄水の生菌数および槽内壁の状態を1週に一回の頻度で調べた。
実施例1~4の殺菌・抗菌剤を用いた場合には、4週間経過時点でも、極液および洗浄水は良好な状態を保ち、微生物膜やぬめりの発生はなかった。本発明の殺菌・抗菌剤によれば、連続添加をしなくても、殺菌・抗菌性を長期間持続させることができる。
一方、極液貯槽およびディップ水洗槽のいずれにも抗菌剤を使用しなかった場合には、4週間経過時点で、電着槽の極液中の生菌数が105cfu/mlまで増加し、電極内部に微生物膜の発生が認められた。また、4週間経過時点で、水洗槽内の生菌数は104cfu/mlとなり、水洗槽の内壁にぬめりが生じた。
実施例1~4で得られた殺菌・抗菌剤それぞれの1/10スケール試料をネットに収納し、極液貯槽およびディップ水洗槽からサンプリングした1000mlの極液および洗浄水中に浸した。スターラーでゆっくり攪拌しながら培養し、48時間経過時に生菌数(cfu/ml)を測定した。結果を表1に示す。
なお、1/10スケール試料は、次のようにして調製した。
実施例1および実施例2の電着塗装システム用殺菌・抗菌剤(錠剤)を粗く砕き、微粉末を除き、1/10の質量の塊状固体を試料としてそれぞれ用意した(実施例1および2)。
実施例3で得られた錠剤を粗く砕き、微粉末を除き、1/10の質量の塊状固体を得、該塊状固体を不織布製の小型袋に収納し、ヒートシールにより密封したものを試料として用意した(実施例3)。
実施例4で用いたBIT粉末4gを不織布と直径5mmの穴を5mm間隔で有する厚さ0.1mmのポリエチレンフィルムとをラミネートしてなる2層構造のフィルムからなる小袋に収納し、ヒートシールにより密封したものを試料として用意した(実施例4)。
実際に稼働している電着塗装ラインのUF水洗水(UF膜(ウルトラフィルター)で濾過した循環洗浄水、6トンタンク)に対して、不織布の袋に入れた下記薬剤(200g)を浸漬し、一定期間、水の濁りを観察した。濁りのあるものは微生物の増殖あり、無いものは増殖無しと判断した。薬剤の混合比は1:1(w/w)とした。その結果、以下の通りとなり、薬剤の効果が確認された。
