Description
本出願は、2005年1月14日付で提出した米国仮出願番号60/644,299の利益の保護を請求するものである。
1.発明の属する分野
主題発明は一般に導電性ポリマーに関するものであり、かつより具体的に言えば改善された耐劣化性を有し、電気伝導性で、静電気を逃す効果があり、かつ帯電防止性のポリオキシメチレン組成物に関する。
電気伝導性の高分子材料は、部材からの静電帯電の消散、静電スプレー塗装及び電磁波の透過を防止するための電気部品の遮へいを含め、多くの用途にとって望ましい。ポリマーの電気伝導率を増加させる主な方法は、ポリマーに、導電性添加剤、例えば金属粉末、金属繊維、イオン導電性ポリマー、本質的に導電性のポリマー粉末、例えばポリピロール、炭素繊維又はカーボンブラックで充填することである。しかしながら、これらのアプローチは欠点を有する。例えば、金属繊維及びポリマー粉末は、乏しい耐食性及び不十分な機械的強度を有する。さらに、それらの密度は高質量ローディング(high weight loadings)を必要にする;故に、それらの使用はしばしば実用的でない。
主題発明は、導電性ポリオキシメチレン組成物を提供する。この組成物は、第一ポリオキシメチレン成分、導電性フィラー、少なくとも1つのホウ素のオキシ酸又はその塩、及び少なくとも1つの第一ポリアミドオリゴマーを含んでなる。第一ポリオキシメチレン成分は、オキシメチレンのコポリマー、オキシメチレンのホモポリマー及びそれらの混合物を含んでなり、かつ組成物の全質量を基準として約50〜約99.5質量%の量で存在している。導電性フィラーは、組成物の全質量を基準として約0.1〜約40質量%の量で存在している。
多様な環境に暴露された際に改善された耐劣化性を有する物品を成形するための導電性ポリオキシメチレン組成物が開示される。改善された耐性に加えて、主題発明の組成物から形成された物品は、そしてまた多様な環境に応じて所望の体積抵抗率を提供することができる。例えば、自動車用途の燃料環境における物品は、SAE J1645 "Fuel System-Electrostatic Charge"による106Ωcm未満の体積抵抗率を必要とする。その他の環境は、体積抵抗率が104〜108Ωcmであることが望まれうる。特別な用途に応じて、主題出願は、所望の体積抵抗率を有し、改善された耐劣化性を有する物品を提供することができる。組成物は一般的に、第一ポリオキシメチレン成分、導電性フィラー、少なくとも1つの第一ポリアミドオリゴマー及び少なくとも1つのホウ素のオキシ酸又はその塩を含んでなる。
主題発明による組成物を、他に示されていない限り、組成物の全質量を基準として、質量%による第1表に挙げられた成分から形成した。
