を少なくとも30℃、好ましくは40〜200℃、特に好ましくは80〜150℃のバッチ温度で混合することを含む、実質的にジフェニルグアニジンフリーのゴム混合物を製造するための方法も提供する。その方法は、典型的には、1〜1000sec−1、好ましくは1〜100sec−1の剪断速度で実施する。ポリエチレンイミンの添加は、より高い35℃〜200℃の範囲の温度、好ましくは約40℃の温度で、混合のいかなる時点で実施してもよい。

本発明に関連して、シリカ含有充填剤として採用される物質としては、以下のものが挙げられる:
− シリカ、特に沈降シリカまたはヒュームドシリカ、たとえばケイ酸塩の溶液を沈降させるか、またはハロゲン化ケイ素を火炎加水分解させて製造し、5〜1000、好ましくは20〜400m2/g(BET表面積)の比表面積と、10〜400nmの一次粒径とを有するもの。それらのシリカは、任意選択的に、他の金属酸化物、たとえばAl、Mg、Ca、Ba、Zn、Zr、Tiの酸化物との混合酸化物の形態であってもよい。
− 合成ケイ酸塩、たとえばケイ酸アルミニウム、ケイ酸アルカリ土類金属、たとえば、ケイ酸マグネシウムもしくはケイ酸カルシウムで、20〜400m2/gのBET表面積および10〜400nmの一次粒子サイズを有するもの、
− 天然のケイ酸塩、たとえば、カオリンおよび他の天然産のシリカ、
およびそれらの物質の混合物。
シリカベースの充填剤に加えて、またはそれらに代わるものとして、カーボンブラックを使用することも可能であり、そのために特に好適なカーボンブラックは、ランプブラックプロセス、ファーネスブラックプロセスまたはガスブラックプロセスで製造され、20〜200m2/gのBET表面積を有するもの、たとえば、SAF、ISAF、IISAF、HAF、FEF、およびGPFカーボンブラックである。
表1に示した実施例1および参照例のゴム配合物から加硫物を製造した。この目的のために、実施例1〜3および参照例のそれぞれの成分を、以下において述べるそれぞれの混合プロセスで混合した。次いで、ゴム混合物の完全加硫を150℃で実施した。
・最初に、天然ゴム(NR、たとえばTSR/RSS DEFO 1000)をニーダー(GK 1.5)内に仕込み、添加剤のZINKWEISS ROTSIEGEL、CORAX(登録商標)N339、EDENOR(登録商標)C 18 98−100、VULKANOX(登録商標)4020/LGを80℃未満、好ましくは約40℃の温度において約40回転で添加した。
・次いで、このNRゴム混合物を温度調節されたロール上に置き、製品のCHANCEL 90/95摩砕硫黄、VULKACIT(登録商標)CZ/C、RHENOGRAN(登録商標)DPG−80および/またはポリエチレンイミンを加え、ゴム混合物中に組み入れた。そのロール温度は、100℃未満、好ましくは50℃未満、極めて特に好ましくは約40℃である。
ムーニー粘度の測定:
測定は、ASTM D1646に準拠し、剪断円板式粘度計により測定した。粘度は、ゴム(およびゴム混合物)が、加工に抵抗する力から直接求めることができる。ムーニー剪断円板式粘度計において、襞付きの円板が上下共に試験物質で取り囲まれ、加熱可能なチャンバー内で約2回転/分の速度で回転される。そのために必要とされる力をトルクとして測定し、これがそれぞれの粘度に相当する。試験片は一般的には1分間で100℃に予備加熱し、それから4分かけて測定し、その間、温度は一定に保たれる。粘度は、それぞれの試験条件と共に報告する:たとえば、ML(1+4)100℃(ムーニー粘度、ローターサイズL、予備加熱時間および試験時間(分)、試験温度)。
MDR(ムービング・ダイ・レオメーター)加硫プロファイルおよびそれに伴う分析データは、ASTM D5289−95に準拠し、MDR 2000 Monsantoレオメーターで測定する。ゴムの95%が架橋された時点を完全加硫時間として測定する。選択された温度は150℃であった。
これらの測定は、DIN 53504(引張試験、ロッドS2)に従って実施した。
以下において実施例を使用して本発明を説明するが、それらに限定される訳ではない。
実施例1と同様にして実施例2〜4を実施し、実施例1との唯一の違いは、ポリエチレンイミンを0.6phrより少ない量で用いたことである。参照例および比較例に比べて、低いムーニー粘度を維持しながらも、完全加硫時間(t95)が有利に短くなり、かつ表3に見られるように優れた加硫特性を依然として伴っている。
