Abstract
【解決手段】熱プレス用クッション材1は、織布と、この織布に含浸されたゴムとからなる繊維−ゴム複合材料層を備える。織布の経糸は合撚糸であり、緯糸はガラス繊維からなる嵩高糸である。繊維−ゴム複合材料層は、内部に空隙を有する。
【選択図】図1
Description
では、織布の経糸に合撚糸3を用い、緯糸に嵩高糸(例えば、バルキーヤーン)2を用いている。ゴムは、嵩高糸2内の隙間および織り目の隙間に適度に入り込んでいる。繊維−ゴム複合材料層1は、嵩高糸2内および織り目に入り込んだゴム中に多数の空隙を有している。
織布として、バルキーヤーンを用いたガラス織布「T860」(ユニチカ株式会社製)を用いた。この織布は、緯糸がEガラス繊維(繊維径6μm)3200本よりなる番手305texの合撚糸を嵩高加工したバルキーヤーンであり、経糸がEガラス繊維(繊維系6μm)1600本よりなる番手135texの嵩高加工していない合撚糸であり、経糸と緯糸とを2重織りに製織したものである。この織布は、重量が850g/m2、厚みが1.02mm、空隙率が67%である。一方、酢酸ブチルとメチルエチルケトンとを質量比1:1の割合で混合した溶剤に、未加硫フッ素ゴムを所定の濃度で溶解してなる未加硫フッ素ゴム溶液を用意した。各未加硫フッ素ゴム溶液の固形分割合は、表1に示すとおりとした。ガラス織布を各未加硫フッ素ゴム溶液に浸漬した後、それぞれ2本のロールで絞った。次いで、未加硫フッ素ゴム溶液が浸透した各ガラス織布を十分に乾燥させて溶剤を除去した。
サンプル10は、ガラス織布として、嵩高糸を用いていない通常の織布を使用した点を除き、サンプル2と同様の熱プレス用クッション材である。すなわち、織布として、Eガラス繊維(繊維系9μm)2400本よりなる番手405texの嵩高加工していない合撚糸を経糸および緯糸に使用して綾織りに製織したガラス織布「A710」(ユニチカ株式会社製)を使用した。この織布は、重量が708g/m2、厚みが0.60mm、空隙率が53.5%である。
サンプル11は、太さ2d、繊維長51mmのメタ系芳香族ポリアミド繊維「コーネックス」(帝人株式会社製)のウエブからなるニードルパンチ不織布を使用した。この不織布は、織り目の開いたガラスクロスに未加硫フッ素ゴムを塗布してなる接着性基布の両面に上記ウエブを積層し、ニードルパンチを施して作成した。不織布は、重量が350g/m2、厚みが2.0mm、空隙率が87.3%であった。次いで、この不織布の上下両面に、サンプル2と同じ表層材をサンプル2と同じ方法で積層一体化し、ニードルパンチ不織布と表層とが積層一体化した構造の熱プレス用クッション材を得た。
各サンプルについて、反復クッション性を測定した。クッション性の測定条件を、図9を参照して説明する。まず、温度210℃の熱板間にサンプルを投入し、2分間の予熱後、1mm/分の圧縮速度で0MPaから1MPaまで加圧する(a)。次いで、加圧力1MPaの状態で20分間保持する(b)。続いて、1mm/分の圧縮速度で1MPaから4MPaまで昇圧する(c)。次いで、加圧力4MPaの状態で20分間保持した後、加圧力を開放する(d)。(a)−(b)−(c)−(d)を1プレスサイクルとした。
