Abstract
Description
図1は、本発明のクッションパッドの変形を検出するシステムを車載座椅子に応用する場合を示す模式断面図である。
図2は、本発明の磁性エラストマーの働きを示す模式図である。
図3は、本発明のクッションパッドの斜視図を模式的に表した図である。
一般的には、中心線平均粗さ測定器を直読する。測定器は、具体的には、ミツトヨ株式会社製サーフテストSJ−310が挙げられる。磁性エラストマーは、好ましくは算術平均粗さ(Ra)1.0〜8.0μm、より好ましくは1.0〜5.0μmである。算術平均粗さ(Ra)が、0.5μmより小さいとアンカー効果が十分でなく、逆に10μmを超えると発泡ポリウレタンの液周りが十分でないため接着性が低下する恐れがある。
反応容器にポリオールA(グリセリンを開始剤にプロピレンオキシドを付加したポリオキシプロピレングリコール、OH価56、官能基数3)85.2重量部を入れ、撹拌しながら減圧脱水を1時間行った。その後、反応容器内を窒素置換した。次いで、反応容器にトルエンジイソシアネート(三井化学株式会社製、2,4体=100%、NCO%=48.3%)14.8重量部を添加して、反応容器内の温度を80℃に保持しながら3時間反応させてイソシアネート末端プレポリマーA(NCO%=3.58%)を合成した。
反応容器にポリオールC(ペンタエリスリトールを開始剤にプロピレンオキシドを付加したポリオキシプロピレングリコール、OH価75、官能基数3)81.2重量部を入れ、撹拌しながら減圧脱水を1時間行った。その後、反応容器内を窒素置換した。次いで、反応容器にトルエンジイソシアネート(三井化学株式会社製、2,4体=100%、NCO%=48.3%)18.8重量部を添加して、反応容器内の温度を80℃に保持しながら3時間反応させてイソシアネート末端プレポリマーB(NCO%=4.55%)を合成した。
ポリオールA213.0重量部およびオクチル酸ビスマス(日本化学産業株式会社製、プキャット25)0.38重量部の混合液にネオジム系フィラー(愛知製鋼株式会社製、MF−15P)730.3重量部を添加し、フィラー分散液を調製した。このフィラー分散液を減圧脱泡し、同様に減圧脱泡した上記プレポリマーA100.0重量部を添加し、自転・公転ミキサー(シンキー株式会社製)にて混合および脱泡した。この反応液を1.0mmのスペーサーを有する離型処理したPETフィルム上に滴下し、ニップロールにて厚み1.0mmに調整した。その後、80℃で1時間キュアを行って、フィラー分散ポリウレタンエラストマーを得た。得られた該エラストマーを着磁装置(電子磁気工業株式会社製)にて1.3Tで着磁することにより、磁性エラストマーを得た。
得られたクッションパッドについて、50万回の耐久試験を行い、初期値に対するセンサー特性の変化率から特性安定性を求めた。センサー特性は10kPaの圧力を印加したときのホール素子の出力電圧変化率から求めた。なお、圧力印加には40mmφの面圧子を用いた。
使用する配合処方を表1に記載するものを用いて、磁性エラストマーを作成し、実施例1と同様の方法でクッションパッド作成して、算術平均粗さ(Ra)および最大高さ粗さ(Rz)を測定し、かつ特性安定性を評価した。結果を表1に示す。尚、実施例11は、軟質発泡ポリウレタンと一体成形を行わずに、別々に成形した後、両面テープで貼り付けたものについて、同じ評価を行った。比較例1は、サンドペーパーで粗面化処理しないものであり、比較例2は、サンドペーパー#60で粗面化したものであり、非常に粗い状態のものの例である。
