Abstract
【解決手段】ゴム組成物に、高電圧電気絶縁特性の向上に資する添加剤を添加して得られたポリマー碍子用外被ゴムであって、前記添加剤を、セラミックスの水和物を100nm以下に粉砕して得た微粉末とし、その添加量を、ポリマー碍子用外被ゴムの全原料中、0.5〜2.5質量%とした。
【選択図】なし
Description
(イ)平均組成式が、R1 aSiO(4-a)/2で示され、1分子中に少なくとも平均2個以上のアルケニル基を有するオルガノポリシロキサン100重量部。(式中R1は置換又は非置換の一価炭化水素基であり、R1の0.01〜20モル%はアルケニル基である。aは1.9〜2.4の正数である。)
(ロ)平均組成式が、R2 bHcSiO(4-b-c)/2で示され、常温で液体のオルガノハイドロジェンポリシロキサン0.1〜100重量部。(式中R2は炭素数1〜10の置換又は非置換の一価炭化水素基でり、bは0.7〜2.1、好ましくは1〜2、cは0.002〜1、好ましくは0.01〜0.5で、かつb+cは0.8〜3、好ましくは1.5〜2.6を満足する正数である。)
(ハ)触媒量(1〜100ppm)の付加反応触媒
比較例1,3,4は何れも、上記試験条件をクリアすることができず、エロージョン深さ6mm(=試料貫通)、エロージョン長さ25mm以上であった。実施例1〜5および比較例2,5,6,7は、何れも、上記試験条件をクリアし、平均エロージョン深さ1.5mm、平均エロージョン長さ5〜6mmに抑制された。
(耐アーク特性)
比較例1では200秒、比較例3では300秒であったのに対し、実施例1〜5および比較例2,4,5,6,7では、何れも、検出上限である420秒以上と、比較例に対し大幅な向上が確認された。
(機械的特性)
JIS K6251の引き裂き強度試験において、実施例1〜5では、何れも、比較例1に対し、引き裂き強度の向上が確認された。一方、比較例2〜4および比較例7の引き裂き強度は、比較例1に比して、ほぼ同等か若干低下しており、引き裂き強度の向上効果は認められなかった。
・添加剤をセラミックスの水和物を100nm以下に粉砕して得た微粉末とし、その添加量を、0.5〜2.5質量%とすることにより、ポリマー碍子用外被ゴムに、従来技術(非特許文献1、2)と同等の高電圧電気絶縁特性を具備させることができるとともに、前記従来技術よりもすぐれた機械的特性を具備させることができることが確認された。
・添加剤をμサイズにした場合、添加剤の大量添加によって、ポリマー碍子に必要とされる高電圧電気絶縁特性を具備させることができるが、添加剤の大量添加によって、機械的特性が低下することが確認された。
・添加剤の種類を無水シリカとした場合、ポリマー碍子に必要とされる高電圧電気絶縁特性を具備させるためには、添加剤の添加量を3質量%以上とすることが必要であることが確認された。
