Abstract
Description
タイヤは、良好なウェットスキッド(濡れ滑り)抵抗、低い転がり抵抗、及び良好な摩耗特性を有することが非常に望ましい。タイヤの摩耗特性をそのウェットスキッド抵抗及びトラクション(牽引)特性を犠牲にせずに改良することは従来非常に困難であった。これらの性質は、タイヤの製造に利用されるゴムの動的粘弾性に依存するところが大きい。

(B)約60〜約10phrのポリブタジエン;及び
(C)5〜50phrの、−40℃〜20℃の範囲のTgを有する炭化水素樹脂;
(D)任意に、ゴムプロセスオイル;
(E)任意に、20℃より高いTgを有する炭化水素樹脂;
(F)70〜130phrのシリカ
を含み、
炭化水素樹脂とオイルの総量は65phr未満であり、シリカの炭化水素樹脂とオイルの総量に対する重量比は2より大きい
加硫可能ゴム組成物を含むトレッドを有する空気入りタイヤに向けられる。
(A)約40〜約90phrの、−40℃〜0℃の範囲のガラス転移温度(Tg)を有する溶液重合スチレン−ブタジエンゴム;

のものである。
RN−(CH2)XSi(OR’)3 III
[式中、窒素(N)原子と結合したRは保護アミン基で、適切な後処理により第一アミンを生じ、R'は、アルキル、シクロアルキル、アリル、又はアリールから選ばれる1〜18個の炭素原子を有する基を表し;そしてXは1〜20の整数である]の任意の化合物でありうる。一態様において、少なくとも一つのR'基はエチル基である。適切な後処理により第一アミンを生じるとは、リビングポリマーと保護第一アミノ基及びアルコキシシリル基を有する化合物との反応後、保護基が除去されることを意味する。例えば、N,N−ビス(トリメチルシリル)アミノプロピルトリエトキシシランにあるようなビス(トリアルキルシリル)保護基の場合、加水分解を使用してトリアルキルシリル基を除去し、第一アミンを遊離させる。
アルコキシシラン基と第一アミン基で官能化された適切なスチレン−ブタジエンゴムは、Japan Synthetic Rubber(JSR)社製のHPR 340など、市販されている。
(R4O)xR4 ySi−R5−S−SiR4 3 VII
[式中、Siはケイ素であり;Sは硫黄であり;Oは酸素であり;xは1、2及び3から選ばれる整数であり;yは0、1、及び2から選ばれる整数であり;x+y=3であり;R4は同じか又は異なり、(C1−C16)アルキルであり;そしてR’は、アリール、及びアルキルアリール、又は(C1−C16)アルキルである]によって表されるシラン−スルフィド変性剤との反応生成物を含む。一態様において、R5は(C1−C16)アルキルである。一態様において、各R4基は同じか又は異なり、それぞれ独立にC1−C5アルキルであり、R5はC1−C5アルキルである。
ゴム組成物は、5〜50phrの、−40℃〜20℃のガラス転移温度を有する炭化水素樹脂を含む。樹脂のTgの適切な測定法は、ASTM D6604又は同等規格に準拠したDSCである。炭化水素樹脂は、ASTM E28による測定で0℃〜70℃の軟化点を有する(環球式軟化点と呼ばれることもある)。一態様において、ゴム組成物はさらに、20℃より高いガラス転移温度を有する炭化水素樹脂を含んでいてもよい。そのような任意選択の炭化水素樹脂は70℃より高い軟化点を有しうる。
スチレン/アルファメチルスチレン樹脂は、本明細書においては、スチレンとアルファメチルスチレンの比較的短鎖コポリマーと見なされている。スチレン/アルファメチルスチレン樹脂は、例えば、約10〜約90パーセントの範囲のスチレン含量を有しうる。一側面において、そのような樹脂は、例えば、炭化水素溶媒中でのスチレンとアルファメチルスチレンのカチオン共重合により、適切に製造できる。従って、想定しているスチレン/アルファメチルスチレン樹脂は、例えば、その化学構造、すなわちそのスチレン及びアルファメチルスチレン含量により、そしてそのガラス転移温度、分子量及び分子量分布により特徴付けられる。適切なスチレン/アルファメチルスチレン樹脂は、Rutgers Novares GmbH社よりPURE 20 ASとして市販されている。
ゴム組成物は、任意選択のプロセスオイル、Tgが20℃より高い任意選択の炭化水素樹脂及びTgが−40℃〜20℃の炭化水素樹脂の組合せを65phrまでの量で含む。
一態様において、シリカの、炭化水素樹脂とオイルの総量に対する重量比は2より大きい。一態様において、シリカの、炭化水素樹脂とオイルの総量に対する重量比は2.2より大きい。
