Description
本発明は、腐食抵抗性コーティングに関する。詳しくは、本発明は、炭素を含有する腐食抵抗性コーティングに関する。
コーティングは、数多くの理由によって使用される。一般に、工場では電化製品、自動車、航空機および類似物などの所定の基板または製品に、製品コーティングまたは産業コーティングが塗布される。一般に、航空機産業を含む多くの産業は、腐食保護および改善された性能の両方を提供するコーティングシステムを使用する。
有効腐食抑制量の腐食抑制炭素顔料を含むコーティング組成物が提供される。一つの実施態様では、腐食抑制炭素顔料は、生成するコーティング膜の腐食抵抗性を高めるために、一つ以上の弱酸性を生じる増量剤(例えば、金属硫酸塩、リン酸塩等)、希土類化合物(例えば、酸化物、酸化物固溶体およびそれらの混合物、塩、希土類錯体および類似物)、アミノ酸およびアミノ酸誘導体、ゼラチンおよびゼラチン誘導体、有機系交換樹脂、およびそれらの組み合わせと組み合わされる。一つの実施態様では、腐食抑制炭素顔料は、表面改質した腐食抑制炭素顔料である。
以下の詳細な説明では、当業者が本発明を実施することができるように、十分詳細に実施態様を説明する。その他の実施態様を利用してもよく、本発明の技術思想および範囲から逸脱することなく構造、論理およびその他の変化を施してもよい。従って、以下の詳細な説明は、限定的な意味で解釈されるべきではない。以下の詳細な説明は、用語に関するセクションで始まり、炭素に関する概論および本発明のさまざまな実施態様の説明がそれに続く。その後で一連の実施例を提示し、それから短い結論を示す。
本明細書で用いられる用語「基板」は、固有の性質を提供するために清浄にし、および/または保護し、および/または改質することができる表面を有する構造物を指す。腐食抑制コーティングを塗布することについては、そのような基板は一般に金属であるが、「基板」はいかなる特定の種類の物質にも限定されない。しかし、腐食抑制コーティングは、重合体基板(例えば被覆金属基板)などのその他の基板に塗布してもよい。腐食抑制コーティングは、炭素繊維およびエポキシ樹脂で作られた基板などのコンポジット基板に塗布してもよい。コンポジット基板は腐食しないが、それでも、コーティングは基板材料と適合しなければならない制約はあるものの、表面保護および/またはその他の固有の性質を基板に提供するために、コンポジット基板で腐食抑制コーティングを用いてもよい。いくつかの場合には、基板の主な部分はコンポジット材料から作られ、従って腐食からの保護を必要としないが、所望のコーティング区域内の他の金属表面、例えば金属リベットの存在のために、腐食抑制コーティングの使用が必要である。
「0026」トップコート、自己プライマトップコート、および強化自己プライマトップコートは、時間とともに乾燥または硬化、すなわち溶媒が蒸発するウェットまたは「十分に硬化していない」状態で基板に塗布してよい。コーティングは、膜または「硬化した」塗料を作製するために、自然にまたは加速手段、例えば紫外線硬化システムによって乾燥してよい。コーティングは、接着剤などの半硬化状態または十分硬化した状態で塗布してもよい。
周期律表の第IV族に位置する原子量12の元素炭素は、有機および無機化学用途の主要構成元素である。高い融点および沸点は、望ましいレベルの安定性を提供し、原子構造は、等極性および異極性両方の固有の結合のさまざまな機会を提供する。固体炭素の主な形は、ダイヤモンド、結晶性および非晶質である。主な結晶相は、炭素原子のシート型配置からなる黒鉛である。炭素シートは剥離できるが、容易には破れない。このシートの中で、炭素原子は、ベンゼン型配置で結合し、シート同士は、ファンデルワールス力によって保持される。シートに平行な電気伝導率は、垂直な方向より何桁も大きい。シートの間隔は、さまざまな化学種のインターカレーションを可能にする距離3.4Åである。インターカレーションした化学種は、その後、炭素の化学的挙動において活性となることがある。「フラーレン」など、特定のカテゴリーに当てはまらないその他の非常に特別な構造形も製造された。
組成物
一つの実施態様では、本発明は、生成するコーティング膜の腐食抵抗性を改善するために、腐食抑制炭素顔料をさまざまな濃度で含むコーティングを提供する。一つの実施態様では、コーティングは、液体、例えば塗料として塗布される水系または溶剤系コーティング組成物である。他の実施態様では、コーティングは、粉体またはペースト(例えばゾルゲル)の形で塗布される。さらに他の実施態様では、コーティングは、シーラント、導電性重合体または類似物である。
本発明は、さらに上記コーティング組成物を調製し使用するプロセスに関する。塗料を製造する任意の従来法を用いてよい。そのような方法の例は、圧縮空気または電気によって動力を供給されるボール盤、適切な粉砕媒体を用いるサンドミルおよび類似物の使用を含むが、それらに限定されない。そのような方法は、当業者に既知であり、本明細書では詳細に説明しない。
一つの実施態様では、コーティング組成物は、自己プライマトップコート組成物または強化自己プライマトップコート組成物である。これらのコーティング組成物は、アルミニウム、アルミニウム合金、アルミニウム鋳物、マグネシウム、マグネシウム合金、チタン、亜鉛、亜鉛被覆鋼、亜鉛合金、亜鉛−鉄合金、亜鉛−アルミニウム合金、無垢および電解鋼、ステンレス鋼、酸洗い鋼、鉄化合物、マグネシウム合金などの金属、例えばクロム系化成皮膜、陽極処理コーティング、コバルト系化成皮膜、リン酸塩系化成皮膜、シリカ系化成皮膜、希土類系化成皮膜およびステンレス金属前処理などの金属前処理を有する基板、および重合体、重合体/金属コンポジット、コンポジット、塗布基板、および類似物に用いてよい。

試験するコーティング組成物を種々の金属基板に吹き付け、時間をかけて、一般に約1週間自然に乾燥(硬化)させた。試料の辺および背面にテープを貼り、ASTM B117の手順に従って前面に「X」パターンをケガキした。結果を表12〜14に示す。
本明細書で示したように、腐食抑制炭素顔料を添加すると、さまざまなコーティング組成物の腐食抑制性が改善される。腐食抑制炭素顔料が機能する正確な機構は不明であるが、腐食抑制炭素顔料が存在すると、ほとんどの場合に、コーティングシステムの腐食抵抗性が改善されることを見いだした。特定の界面活性剤で分散したカーボンブラックおよび/または樹脂で分散したカーボンブラックも有益なことがあるが、それらの存在が他の顔料成分を分散させる助けとなることもある。
化学的および機械的安定性、良好な伝導性、表面反応速度に合わせられる広範な構造形の利用可能性、表面を化学的に改質できることおよび比較的低いコストのために、炭素は、電解プロセスで陽極または陰極として効果的に使用できることも知られている。電極として用いられることが報告されている炭素のいくつかの形は、さまざまなグレードおよび空げき率の黒鉛、ガラス状炭素および熱分解黒鉛、網状炭素、炭素繊維、球体およびフレーク、表面改質炭素および層間化合物炭素を含む。
従って、腐食からの直接の化学的または電気化学的な保護を炭素が提供するとは期待されないし、実際、この点に関しては有害であり得る(米国特許第4,544,581号明細書を参照)と思われていたのであるが、本発明は、適当な状況では、炭素は金属表面の長期腐食抑制性に顕著な援護を与える適当な環境を提供することがあり得ることを初めて実証する。クロム酸塩、ナルザンTM、ブサンTM、ハロックスTM、モリホワイトTM、導電性重合体、および類似物などの従来の塗料抑制剤とともに存在するとき、このことが特に成立することがある。全体的な腐食抑制活性を改善することが塗料中の成分としての炭素の主な役割である。本発明は、クロム酸ストロンチウム等などのクロム酸塩を有しないという一層の利点を提供し、従って、現在知られているクロム含有コーティングシステムより環境的に優れている。
