Description
本発明のカーカスプライ用ゴム組成物において、ゴム成分は、天然ゴムおよび変性天然ゴムからなる天然ゴム成分を含有する。本発明におけるゴム成分は、このような天然ゴム成分を10〜100質量%の範囲内で含有することが好ましい。
本発明において、ゴム成分中の天然ゴム成分の含有率は50質量%以上であることが好ましい。ゴム成分中の天然ゴム成分の含有率が50質量%未満であると、石油資源由来の原料の使用量の低減効果が十分得られない傾向にあるためである。ゴム成分中の天然ゴム成分の含有率は、70質量%以上であることが好ましく、90質量%以上であることがより好ましい。石油資源由来の原料の使用量の低減効果が良好である点で、ゴム成分中の天然ゴム成分の含有率は100質量%である(すなわち、ゴム成分が天然ゴム成分からなる)ことが好ましいが、たとえばゴム成分中の天然ゴム成分の含有率を50質量%以下、さらに30質量%以下とし、ゴム成分中の残部として天然ゴム成分以外のゴムを配合しても良い。
本発明のカーカスプライ用ゴム組成物は上述したゴム成分に加え、シリカを含有する。シリカは、補強用充填剤として機能するものであり、シリカを配合することにより、得られるカーラスプライにおけるゴム組成物の引張強度を向上させることができる。また、シリカは石油外資源由来であるため、たとえばカーボンブラックなどの石油資源由来の補強剤を主な補強剤として配合する場合と比べて、ゴム組成物中の石油資源由来の原料の使用量を低減できる。本発明のカーカスプライ用ゴム組成物は、上述したゴム成分100質量部に対し20〜60質量部のシリカを含有する。
本発明のカーカスプライ用ゴム組成物は、テルペン系樹脂およびロジン系樹脂のうちの少なくともいずれかを含有する。中でも、テルペン系樹脂を含有することが特に好ましい。なお、複数種のテルペン系樹脂、ロジン系樹脂を含有していてもよい。
本発明のカーカスプライ用ゴム組成物は、上述したようにシリカを含有するが、このシリカとともに、シランカップリング剤を配合することが好ましい。シランカップリング剤としては、従来公知のシランカップリング剤を用いることができ、たとえば、ビス(3−トリエトキシシリルプロピル)テトラスルフィド、ビス(2−トリエトキシシリルエチル)テトラスルフィド、ビス(4−トリエトキシシリルブチル)テトラスルフィド、ビス(3−トリメトキシシリルプロピル)テトラスルフィド、ビス(2−トリメトキシシリルエチル)テトラスルフィド、ビス(4−トリメトキシシリルブチル)テトラスルフィド、ビス(3−トリエトキシシリルプロピル)トリスルフィド、ビス(2−トリエトキシシリルエチル)トリスルフィド、ビス(4−トリエトキシシリルブチル)トリスルフィド、ビス(3−トリメトキシシリルプロピル)トリスルフィド、ビス(2−トリメトキシシリルエチル)トリスルフィド、ビス(4−トリメトキシシリルブチル)トリスルフィド、ビス(3−トリエトキシシリルプロピル)ジスルフィド、ビス(2−トリエトキシシリルエチル)ジスルフィド、ビス(4−トリエトキシシリルブチル)ジスルフィド、ビス(3−トリメトキシシリルプロピル)ジスルフィド、ビス(2−トリメトキシシリルエチル)ジスルフィド、ビス(4−トリメトキシシリルブチル)ジスルフィド、3−トリメトキシシリルプロピル−N,N−ジメチルチオカルバモイルテトラスルフィド、3−トリエトキシシリルプロピル−N,N−ジメチルチオカルバモイルテトラスルフィド、2−トリエトキシシリルエチル−N,N−ジメチルチオカルバモイルテトラスルフィド、2−トリメトキシシリルエチル−N,N−ジメチルチオカルバモイルテトラスルフィド、3−トリメトキシシリルプロピルベンゾチアゾリルテトラスルフィド、3−トリエトキシシリルプロピルベンゾチアゾールテトラスルフィド、3−トリメトキシシリルプロピルメタクリレートモノスルフィド、3−トリメトキシシリルプロピルメタクリレートモノスルフィドなどのスルフィド系;3−メルカプトプロピルトリメトキシシラン、3−メルカプトプロピルトリエトキシシラン、2−メルカプトエチルトリメトキシシラン、2−メルカプトエチルトリエトキシシランなどのメルカプト系;ビニルトリエトキシシラン、ビニルトリメトキシシランなどのビニル系;3−アミノプロピルトリエトキシシラン、3−アミノプロピルトリメトキシシラン、3−(2−アミノエチル)アミノプロピルトリエトキシシラン、3−(2−アミノエチル)アミノプロピルトリメトキシシランなどのアミノ系;γ−グリシドキシプロピルトリエトキシシラン、γ−グリシドキシプロピルトリメトキシシラン、γ−グリシドキシプロピルメチルジエトキシシラン、γ−グリシドキシプロピルメチルジメトキシシランなどのグリシドキシ系;3−ニトロプロピルトリメトキシシラン、3−ニトロプロピルトリエトキシシランなどのニトロ系;3−クロロプロピルトリメトキシシラン、3−クロロプロピルトリエトキシシラン、2−クロロエチルトリメトキシシラン、2−クロロエチルトリエトキシシランなどのクロロ系;などを挙げることができる。これらのシランカップリング剤は、単独で用いてもよく、2種以上を組み合わせて用いてもよい。
本発明のカーカスプライ用ゴム組成物は、本発明の効果を損なわない範囲で、補強剤としてカーボンブラックをさらに含有することが好ましい。カーボンブラックを配合することによって、カーカスプライ用ゴム組成物に良好な機械的強度が付与されるが、カーボンブラックは一般に石油資源由来であるため、石油資源由来の原料の使用量を低減するためには、カーボンブラックの配合量は、ゴム成分100質量部に対して15質量部以下、さらに5質量部以下、さらに3質量部以下であることが好ましい。一方、カーボンブラックを配合することによる機械的強度の向上効果を良好に得る点では、カーボンブラックの配合量が、ゴム成分100質量部に対して5質量部以上であることが好ましく、10質量部以上であることがより好ましい。
本発明のカーカスプライ用ゴム組成物には、上記した成分以外にも、従来ゴム工業で使用される他の配合剤、たとえば加硫剤、ステアリン酸、加硫促進剤、加硫促進助剤、オイル、硬化レジン、ワックス、老化防止剤などを配合しても良い。
老化防止剤としては、アミン系、フェノール系、イミダゾール系、カルバミン酸金属塩などを適宜選択して使用することができる。
=(本発明のゴム組成物の粘着力/基準配合ゴム組成物の粘着力)×100
なお、上記計算式中の基準配合ゴム組成物は、テルペン系樹脂、ロジン系樹脂を含有しないこと以外は同じ本発明のゴム組成物と同様の組成に配合されたゴム組成物を指す。
表1に示す配合処方に従い、神戸製鋼所(株)製1.7Lバンバリーミキサーを用いて、硫黄および加硫促進剤を除く配合成分を充填率が58%になるように充填し、回転数80rpmで140℃に到達するまで3分間混練りした。ついで、得られた混練り物に硫黄および加硫促進剤を表1に示す配合量で加えた後、オープンロールを用いて、80℃で5分間混練りし、実施例1および比較例1、2に係る配合の未加硫ゴム組成物を得た。
(1)天然ゴム(NR):RSS#3(テックビーハング社製)
(2)エポキシ化天然ゴム(ENR):ENR25(クンプーランガスリー社製)(エポキシ化率:25%)
(3)カーボンブラック:ショウブラックN220(キャボットジャパン(株)製)
(4)シリカ:ウルトラジルVN3(デグッサ社製)
(5)シランカップリング剤:Si69(デグッサ社製)
(6)オイル:NH60(出光興産(株)製)
(7)樹脂(1):石油系樹脂(マルカレッツT100AS(丸善石油化学(株)製))
(8)樹脂(2):テルペン系樹脂(PX300N(ヤスハラケミカル(株)製)
(9)ワックス:サンノックワックス(大内新興化学工業(株)製)
(10)老化防止剤:サントフレックス6PPD(フレキシス社製)
(11)ステアリン酸:桐(日本油脂(株)製)
(12)酸化亜鉛:亜鉛華(三井金属鉱業(株)製)
(13)硫黄:粉末硫黄(鶴見化学(株)製)
(14)加硫促進剤:ノクセラーNS(大内新興化学工業(株)製)
実施例および比較例で得られた未加硫ゴム組成物について、以下の試験を行った。表1には試験結果についても併せて示している。
JIS−T 9233の規定に準拠して、ピクマタックテスタ((株)東洋精機製作所製)を用いて、測定温度23℃、荷重4.9N、放置時間10秒、引き剥がし速度30mm/分の条件下で、未加硫ゴム組成物の粘着力[N]を測定した。さらに、基準配合ゴム組成物として比較例1のゴム組成物の粘着性指数を100とし、下記計算式により、粘着力を指数表示した。粘着性指数が大きいほど粘着力が大きく、優れていることを示す。
今回開示された実施の形態および実施例はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
