Description
表1に示す配合でシリカスラリーにカルボン酸及び/又はアミン、又はカルボン酸のアミン塩を添加し、常温で溶解するまで撹拌した。得られたシリカスラリーを、天然ゴムラテックス(表1中「NRラテックス」と記す。)中の固形成分量100重量部に対してシリカが60重量部になるように配合しメカニカルスターラーを使用して撹拌混合し、天然ゴムラテックスとシリカスラリーの混合液を得た。得られた混合液を、パルス燃焼衝撃波乾燥装置(パルテック社製ハイパルコン小型ラボ用乾燥機)を使用して、パルス燃焼による衝撃波の雰囲気(周波数1000Hz、温度60℃)下に2L/時の流量で噴射して乾燥し、9種類の天然ゴムマスターバッチ(実施例1〜6、比較例2〜4)を製造した。なお、実施例5及び6において、コハク酸及びシクロヘキシルアミンの配合量は、コハク酸のカルボキシル基とシクロヘキシルアミンのアミノ基との当量比が、それぞれ実施例5が1:1、実施例6が1:1.5になるように添加した。また、比較例4において、酢酸及びシクロヘキシルアミンの配合量は、酢酸のカルボキシル基とシクロヘキシルアミンのアミノ基との当量比が1:1になるように添加した。また、比較例1としてカルボン酸及びアミンを配合しない天然ゴムマスターバッチを実施例1と同様にして製造した。
得られた10種類の天然ゴムマスターバッチ(実施例1〜6、比較例1〜4、表2中「NRマスターバッチ」と記す。)を使用し、表2に示す配合でそれぞれ加硫促進剤と硫黄を除く配合成分を秤量し、0.6Lのバンバリーミキサーで4分間混練し130〜140℃で混練物を放出して室温まで冷却した。この混練物に加硫促進剤と硫黄を加え電熱ロールを用いて混合し10種類のゴム組成物(実施例7〜12、比較例5〜8)を製造した。
得られたゴム組成物のムーニー粘度(ML1+4)をJIS K6300に準拠して、ムーニー粘度計にてL型ロータ(38.1mm系、5.5mm厚)を使用し、予熱時間1分、ロータの回転時間4分、100℃、2rpmの条件で測定し、得られた結果を表2に示した。ムーニー粘度が小さいほど粘度が低く成形加工性に優れることを意味する。
得られた試験片のtanδを、岩本製作所社製粘弾性スペクトロメーターを用いて、伸長変形歪率10%±2%、周波数20Hzの条件で、温度60℃におけるtanδを測定し、得られた結果を表2に示した。温度60℃のtanδ(60℃)が小さいほどヒステリシスロスが小さく燃費性能が優れることを意味する。
得られた試験片の耐摩耗性として、JIS K6264に準拠して、ランボーン摩耗試験機(岩本製作所社製)を使用して、室温、荷重49N、スリップ率25%、時間4分の条件で摩耗量を測定した。得られた結果は、天然ゴムマスターバッチの種類毎に比較例5の摩耗量の逆数を100とする指数で表わし表2に示した。この指数が大きいほど耐摩耗性に優れることを意味する。
