Description
前記ゴム成分100質量部に対して、前記充填剤が40~125質量部、前記水素添加樹脂が5~50質量部、前記非イオン系界面活性剤が0.1~7質量部であり、
前記水素添加樹脂が、C5系樹脂であることを特徴とするものである。
条件:
1)カラム:昭和電工株式会社製、Shodex(登録商標)KF807Fを2本使用
2)溶離液:テトラヒドロフラン
3)測定温度:40℃
本発明のタイヤ用ゴム組成物は、イソプレン骨格を有するゴムおよびスチレンブタジエンゴムを含んだゴム成分と、充填剤と、軟化点が110℃より高く、ポリスチレン換算の重量平均分子量が200~1600g/molである水素添加樹脂(以下、「水添樹脂」とも称す)と、非イオン系界面活性剤と、を含むタイヤ用ゴム組成物である。そして、各成分の配合量は、ゴム成分100質量部に対して、充填剤が40~125質量部、水素添加樹脂が5~50質量部、非イオン系界面活性剤が0.1~7質量部である。以下、これらの成分について詳細に説明する。
本発明のゴム組成物は、ゴム成分として、イソプレン骨格を有するゴムとスチレンブタジエンゴム(以下、「SBR」ともいう)とを用いる。イソプレン骨格を有するゴムとしては、例えば、天然ゴム(NR)、ポリイソプレンゴム(IR)等が挙げられる。ゴム成分がイソプレン骨格を有するゴムを含有することで加硫ゴムの破壊強度を高めることができる。その結果、タイヤの転がり抵抗を低くすることができ、また、加硫ゴムの耐摩耗性に優れたものとなる。SBRについても特に制限はないが、溶液重合SBR、乳化重合SBR等を用いることができる。イソプレン骨格を有するゴムやSBRは、それぞれ、単独で用いてもよく、2種以上を併用してもよい。
本発明のゴム組成物における充填剤としては、通常ゴムの充填剤として用いられているものであれば、本発明の効果を損なわない限り、特に制限はないが、充填剤として、少なくともカーボンブラックを含むことが好ましい。カーボンブラックは、加硫ゴムを補強して、加硫ゴムの耐摩耗性を向上させるという効果を奏する。さらに、本発明のゴム組成物においては、充填剤として、さらにシリカを含むことが好ましい。シリカは、タイヤの機械的強度を向上し、転がり抵抗をより低くするという効果を奏する。充填剤の配合量は、ゴム成分100質量部に対して、充填剤が40~125質量部であり、45質量部以上がより好ましく、50質量部以上が更に好ましい。また、110質量部以下がより好ましく、100質量部以下がより好ましく、90質量部以下が更に好ましい。
本発明のゴム組成物に用いる水添樹脂は、軟化点が110℃より高く、ポリスチレン換算の重量平均分子量が200~1600g/molである。水添樹脂の原料となる樹脂としては、C5系樹脂、C5-C9系樹脂、C9系樹脂、テルペン系樹脂、ジシクロペンタジエン系樹脂、テルペン-芳香族化合物系樹脂等が挙げられ、これら樹脂は、1種単独で用いてもよいし、2種以上を組み合わせて用いてもよい。
・カラム温度:40℃
・注入量:50μL
・キャリアー及び流速:テトラヒドロフラン 0.6mL/min
・サンプル調製:樹脂成分約2.5mgをテトラヒドロフラン10mLに溶解
本発明のゴム組成物は、非イオン系界面活性剤を含有する。非イオン系界面活性剤は、得られるタイヤ用ゴム組成物の低燃費性と耐摩耗性を向上させる。非イオン系界面活性剤としては、多価アルコール型、ポリオキシエチレンアルキルエーテル型、ポリオキシエチレンアルキルフェニルエーテル型、ポリオキシエチレンポリオキシプロピレングリコール型、ポリエチレングリコール型、グリコシド型、および脂肪酸アルカノールアミド型等の中から選ばれる少なくとも1種が用いられる。
本発明のゴム組成物においては、通常、ゴム工業界で通常使用される配合剤、例えば、硫黄、老化防止剤、軟化剤(オイル)、ワックス、ステアリン酸、亜鉛華、加硫促進剤、加硫促進助剤等を、本発明の目的を阻害しない範囲内で、必要に応じて用いることができる。
表1、2に示す配合で、常法に従って各ゴム組成物を製造した。なお、表中の変性SBR-Aおよび変性SBR-Bの詳細は下記のとおりである。得られた各ゴム組成物につき、下記手順に従い、粘弾性を測定した。-5℃におけるtanδ(-5°tanδ)は、ウェットグリップ性能(表中、WET指数)の指標となり、50℃におけるtanδ(50℃tanδ)は、転がり抵抗性能(表中、RRC指数)の指標となる。これらの数値は大きいほど効果が優れていることを意味する。
ブチルリチウムを開始剤として得られるSBRであって、末端をN,N-ビス(トリメチルシリル)-3-[ジエトキシ(メチル)シリル]プロピルアミンで変性したものであり、ガラス転移温度は-62℃である。なお、Tgの測定方法は以下に示すとおりである。
ブチルリチウムを開始剤として得られるSBRであって、末端をN-(1,3-ジメチルブチリデン)-3-トリエトキシシリル-1-プロパンアミンで変性したものである。Tgは-38℃である。
グリセリン脂肪酸エステルは、国際公開第2014/098155号の製造例1に記載の方法に従い、脂肪酸をオクタン酸から同モル量のパーム油由来硬化脂肪酸に変えて合成し、更に分子蒸留することで調整したもの(グリセリン脂肪酸エステル組成物)を用いた。なお、得られたグリセリン脂肪酸エステルのグリセリン脂肪酸モノエステル含有量は97質量%であった。
得られたゴム組成物を常法に従って加硫後、粘弾性測定装置(レオメトリックス社製)を使用し、温度-5℃および50℃、動歪1%、周波数52Hzでtanδを測定した。得られた結果は、比較例4のtanδを100として、それぞれ指数表示した。指数値が大きい程、ウェットグリップ性能および低燃費性能が優れていることを示す。なお、ウェットグリップ性能は100以上、低転がり抵抗性能は90以上、かつ、これらの合計が202以上のものを合格とした。
TAインスツルメンツ社製DSC250を用い、ヘリウム50mL/分の流通下、-100℃から20℃/分で昇温しながらDSC曲線を記録し,DSC微分曲線のピークトップをガラス転移温度とした。
