Description
親水性活性炭は水分の吸着も良好であるが、その表面は酸性であり、相手材の発錆を促進すると考えられ、摩擦材に使用されることは無かった。
親水性活性炭は摩擦材組成物全量に対し0.4〜5重量%配合するのが好ましい。
この範囲であれば、錆固着抑制効果がより向上し、耐摩耗性がより良好となる。
親水性のフェノール樹脂の配合量が摩擦材組成物全量に対し、8〜12重量%の範囲であると、錆固着の抑制効果がより向上する。
シリコーンで変性したフェノール樹脂や、フッ素ポリマーを分散させたフェノール樹脂は撥水性を有するため、その摩耗粉が活性炭に吸着されると、活性炭は水分を吸着し難くなり、錆固着抑制効果の更なる向上は望めない。
表1及び2に示す組成の摩擦材組成物をレディゲミキサーにて5分間混合し、予備成型金型内で30MPaにて1分加圧して予備成型をした。
この予備成型物を、予め洗浄、表面処理、接着剤を塗布した鋼鉄製のバックプレート上に重ね、熱成型型内で成型温度150℃、成型圧力30MPaの条件下で6分間加熱加圧成型した後、200℃で4時間熱処理(後硬化)を行い、研磨して乗用車用ディスクブレーキパッドを作製した(実施例1〜12、比較例1)。これらのディスクブレーキパッドの錆固着、耐摩耗性について下記の条件で評価を行った。評価結果を表1及び2に併せ示す。
<錆固着>
JIS D4414「さび固着試験方法」に準拠し、錆固着試験を行い、錆固着力を下記基準にて評価した。
○: 50N以上 150N未満
△: 150N以上 250N未満
×: 250N以上
JASO C427 「自動車−ブレーキライニング及びディスクブレーキパッド−ダイナモメータ摩耗試験方法」に準拠し、制動初速度50km/h、制動減速度0.3G、制動回数適宜、制動前ブレーキ温度100℃、200℃、300℃、400℃の条件で、摩擦材の摩耗量(mm)を測定し、制動回数1000回あたりの摩耗量に換算後、下記基準にて評価した。
○:0.15以上 0.20未満
△:0.20以上 0.25未満
×:0.25以上
