Description
本出願は、米国暫定60/580023号(スミスら(Smith,et al.)により2004年6月15日にされた出願)に基づき優先権を主張し、これは参照をもって開示されたものとする。本出願は更に、スミスらにより出願された米国特許出願「高熱伝導性のコーティングを有する布」に関し、これも参照をもって開示されたものとする。
本発明の技術分野は、電気絶縁に使用される紙の熱伝導率の増大に関する。
家庭電化製品を任意の形で使用する場合、導体を電気的に絶縁することが必要となる。このサイズを連続的に減らすために押圧し、かつ全ての電気電子系を合理化する場合、これに対応して、より良好でよりコンパクトな絶縁体及び絶縁系を見出すことが必要となる。
上記記載を鑑みると、高熱伝導性の(HTC)材料を絶縁紙のホストマトリックス上及び/又はその中に挿入することにより、とりわけ絶縁紙の熱伝導率を促進する本発明と合致する方法及び装置である。本発明にかかるHTC材料は、種々の類型、例えばナノフィラー又は表面コーティングであってよく、かつナノフィラー及び表面コーティングは両方ともそれ自体種々の下位のグループをそれぞれ有する。このHTC材料は、種々の段階で紙に添加することができ、例えば紙がその原料若しくは基材である段階、紙が成形されている段階又は紙が成形された後の段階で添加することができる。雲母は電気抵抗が大きいので、絶縁紙のための特定の種類の基材になる。
本発明は、高熱伝導性(HTC)材料を、紙の絶縁に使用される基材、例えば電気絶縁テープに使用される類型の基材中にか又はその上への導入を提供する。絶縁テープは、ホストマトリックス、例えば雲母を有することが多く、これを紙に成形して、次いでこの紙をしばしば樹脂又は促進剤若しくはこれらの両方で含浸させる。テープに使用される紙を、含浸させる前又は後に、それを引張強さの大きい裏地、例えばガラス又はポリマー皮膜に添加する。絶縁テープのホストマトリックスは、極めて良好な電気絶縁体として作用するが、熱もまた良好に絶縁し、これは不所望な副作用である。
