Abstract
【解決手段】 フッ素樹脂、および電気絶縁性ウィスカーを含有する発泡性組成物、これを発泡させた発泡体、およびフッ素樹脂を含有した発泡体層を絶縁体とした同軸絶縁ケーブル。
【選択図】 なし
Description
同軸絶縁ケーブルを例に挙げると、中心導体の周囲に設ける絶縁層としてフッ素樹脂を含有した発泡体とした場合には、発泡体層を形成しない場合に比べて誘電率が小さなものが得られるので、信号の高速伝送が可能で、電気信号の減衰が小さく特性が優れたケーブルを得ることができる。
電気絶縁性ウィスカーが、ホウ酸アルミニウム、ホウ酸マグネシウム、チタン酸カリウム、窒化ケイ素から選ばれる少なくとも一種である前記の発泡性組成物である。
また、合成樹脂発泡体において、フッ素樹脂および電気絶縁性ウィスカーを有する組成物を発泡剤を混合して発泡させた発泡体である。
また、同軸絶縁ケーブルにおいて、中心導体の周囲にフッ素樹脂および電気絶縁性ウィスカーを含有する組成物を発泡させた発泡体からなる絶縁体層を有する同軸絶縁ケーブルである。
すなわち、これまで発泡核剤として用いられていた窒化ホウ素は、粒子状、鱗片状粒子が用いられていたが、意外にもひげ状の絶縁性のウィスカーを用いることによって発泡率が大きくて微細な気泡を形成することが可能であることを見いだしたものである。
具体的には、ホウ酸アルミニウムウィスカー、ホウ酸マグネシウムウィスカー、チタン酸カリウムウィスカー、窒化ケイ素ウィスカーから選ばれるウィスカーを挙げることができ、これらの一種もしくは複数種を混合して使用することができる。例えば、ホウ酸アルミニウムウィスカーとしては、四国化成製のアルボレックスY(個数平均径0.5〜1μm 個数平均長さ10〜30μm)が挙げられる。また、チタン酸カリウムウィスカーとしては、大塚化学製のティスモD(個数平均径 0.2ないし0.5μm 個数平均長さ10〜20μm)を挙げることができる。
絶縁性ウィスカーの量が0.1質量%よりも少ない場合には発泡率が低下するので好ましくなく、5質量%よりも多い場合には気泡が大きくしたり、電気的特性を低下させる原因となるので好ましくない。
また、本発明に用いる電気絶縁性ウィスカーは、アスペクト比が10〜100程度であり、直径が0.1μm〜1μmであることが好ましく、これよりも大きなウィスカーでは、微細な気泡の形成ができなくなる。
以下に実施例、比較例を示し本発明を説明する。
ここで、C:1m当たりの静電容量(pF)
D:外径(mm)
d:導体の径(mm)
式2 V=(1−logε/logεf)×100
ここで、εf:発泡体層を構成する組成物の発泡前の誘電率
単位長さ当たりの静電容量:75.2pF/m、誘電率εは1.400、気孔率は、54.6%であった。
また、得られた中心導体の被覆体をその軸に垂直な面で切断し、断面を顕微鏡で観察し、顕微鏡写真を図1に示す。
任意に抽出した50個の気泡の平均径は、24.2μmであった。
実施例1において用いた発泡用組成物を、窒化ホウ素粒子を発泡剤として混合したフッ素樹脂組成物(デュポン製 FR5030)に変えた点を除いて同様にして発泡体層を有する中心導体の被覆体を作製し、実施例1と同様にして静電容量を測定した。静電容量 77pF/m、誘電率εは1.434、気孔率は、51.4%であった。
また、得られた中心導体の被覆体をその軸に垂直な面で切断し、断面を顕微鏡で観察し、顕微鏡写真を図2に示す。
任意に抽出した50個の気泡の平均径は、41.7μmであった。
実施例1において用いたホウ酸アルミニウムウィスカーをホウ酸アルミニウム粒子(四国化成製アルボライト03T 個数平均粒径3μm)に変えた点を除いて同様にして発泡体層を有する中心導体の被覆体を作製し、実施例1と同様にして静電容量を測定した。静電容量 78.5pF/m、誘電率εは1.462、気孔率は、48.8%であった。
また、得られた中心導体の被覆体をその軸に垂直な面で切断し、断面を顕微鏡で観察し、顕微鏡写真を図3に示す。
以上の実施例、比較例で示すように、本発明のウィスカーを発泡核剤として形成した発泡体層は、誘電率が低く、窒化ホウ素等の粒子を用いた場合に比べて気孔径の小さな発泡体を形成することができる。
