Description
特に断らないかぎり、実施例及び本明細書の残りの部分における部、百分率、及び比率などはすべて重量に基づくものである。
THV340Zラテックス分散液をPTFE5035Zと混合した後、脱イオン水で希釈して所望の最終固形分含量とした。その後、非フルオロポリマーラテックス(すなわち、ポリウレタンR966若しくはR9649、及び/又はポリアクリラートXK−17)を加え、得られる溶液が均質に見えるようになるまで混合した。次に、ナノ粒子シリカを含む試料について、ナノ粒子シリカ(例えば2326(5nm)又はDVSZN004(45nm))を加えた。最後に、ポリアジリジンCX−100及び必要に応じて用いられるシラン(例えばKH792)を最後の工程で適当な試料に加えた。コーティングに先立って、溶液を少なくとも5時間静置した。代表的な配合物を表1にまとめて示す。各表で用いられる重量比率(%)は、乾燥コーティング中の各成分の量を表す(すなわち、水分は、示される重量比率(%)中には示されていない)。表2は、多くの比較例の配合物を示す。表3は、代替的な非フッ素化ポリマー分散液による低摩擦コーティングの配合物の一覧を示す。
溶液を基材、例えば透明なPETフィルム(2ミル(0.05mm)、プライマー処理していない面)、又は2ミル(0.05mm)のPEフィルム上に、メイヤーバーによって10マイクロメートルの湿潤厚さでコーティングすることによって、各試料を作製した。試料を160℃で2分間加熱した。
透過率及びヘイズを、ビー・ワイ・ケー・ガードナー社(BYK−Gardner GmbH)(ドイツ)より販売されるヘイズガードデュアルを使用して測定した。透過率を記録し、ASTM D1003に従って太陽昼間光の波長範囲(CIE D65標準光源)の平均として計器から直接読み取った。
アメリカン・スリップ・メーター社(American Slip Meter, Inc.)(米国、フロリダ州、エングルウッド)より販売されるAmerican Slip Meter ASM825A摩擦係数(COF)試験機を、2Kgの荷重、及びセンサーとしてネオライトゴムを使用して、静摩擦係数を測定した。3つの異なる領域を試験し、平均を求めた。
乾燥耐摩耗性を、シーン・インスツルメンツ社(Sheen Instruments)(英国、ケンブリッジ)より販売される湿潤摩耗スクラブテスターREF 903により評価した。乾燥摩耗試験は、摩耗媒体として砂を用いないMiaojie研磨パッドを使用して1kgの荷重下で行った。100回の摩耗サイクル後、摩擦係数(COF)及び光学特性(透過率及びヘイズ)を再び試験した。一部の実施例では、試験を200、300、400、及び更には5000回の摩耗サイクルまで継続した。
接触角(CA)を、Drop Shape分析システム(クルス社(Kruss)、DSA100、(ドイツ))上で周囲温度で試験した。同じ試料について5箇所よりも多い異なる位置で測定することにより、平均の接触角(CA)値を得た。水滴の体積は5μLに設定した。研磨試験の前後にこの試験を行った。
所望のコーティング配合物が入れられた浴中にケーブルを通すディップコーティングプロセスによって各試料を作製した。液体コーティング材料の薄膜が通信ケーブルの外被上に残った。このコーティングを、室温、約50℃、約80℃、約100℃、又は約120℃で乾燥させることができる。乾燥温度は、コーティングされるケーブルの種類(すなわち外被材料の組成)及び所望のコーティング速度に基づいて選択することができる。乾燥温度を上げることによってコーティングをより速やかに乾燥させることが可能であり、これにより連続的なコーティングプロセスによってケーブルの長い部分をコーティングして乾燥させることが可能となる。代表的な通信ケーブルとしては、例えば、ポリエチレン外被FRP型ケーブル(ケーブル1として示されるヤンツェ・オプティカル・ファイバー・アンドケーブル(Yangtze Optical Fibre and Cable)社(中国)より販売されるもの、ケーブル2として示されるスリー・エム社(3M company)(中国)より販売されるもの、及びケーブル3として示されるプリスミアン・グループ(Prysmian Group)(イタリア)より販売されるもの)、PVC外被を有する丸形ケーブル(ケーブル4として示されるプリスミアン・グループ(Prysmian Group)(イタリア)より販売されるもの)などが挙げられうる。
図1に示される試験方法に従って潤滑性能を評価した。例えば、図1は、スリー・エム社(3M Company)(米国、ミネソタ州セントポール)より販売される3M(商標)VHB(商標)テープ、例えば3M(商標)4949 VHB(商標)テープのような両面接着テープ(図に示されていない)によって2枚の金属プレート20のそれぞれに固定された4本のケーブル10を有する試験構成の断面図である。試験試料30が、固定された光ケーブルの間に試験試料が挟まれるようにして、固定された光ファイバーケーブルとともに2枚のプレートの間に配置されている。静荷重40が試験装置上に加えられている。試験ケーブルを、制御された速度で試験装置を通じて引っ張る(すなわちページの中に入り込む方向に)。ケーブルを引っ張るのに要した力を記録する。
乾燥耐摩耗性を、シーン・インスツルメンツ社(Sheen Instruments)(英国、ケンブリッジ)より販売される湿潤摩耗スクラブテスターREF 903により評価した。コーティングされたケーブルの長さ約50cmの5つの部分を隣り合わせてスクラブテスターに固定した。摩耗媒体としてMiaojie研磨パッドを使用して1kgの荷重下で、乾燥摩耗試験を行った。33回の摩耗サイクルの後、摩擦係数(COF)を再び試験した。
