Description
なお、本質的にこれら4つの成分で構成されておれば、本発明の趣旨を逸脱しない限り、他の任意成分を若干含んでいてもよい。
まず、珪酸を有する無機充填剤(2)の前処理として付着水分の除去を十分に行うのがよい。具体的には、該充填剤を100℃以上、好ましくは105〜130℃で加熱処理する。該加熱を減圧下で行なってもよい。加熱時間は加熱温度、減圧度等に依存するが、例えば加熱温度が105℃であれば10分以上加熱すればよく、好ましくは1時間から10時間、より好ましく3時間程度である。
温度計、攪拌機、窒素導入管、蒸留装置を備えた500mL四つ口フラスコにハイシル233(PPG(株)社製)を33g、ステアリン酸を0.1g入れ、120℃の油浴中で3時間攪拌し、付着水分を除去した。次いで、ビス(3−トリエトキシシリルプロピル)テトラスルフィドを3.3g加えて1.5時間混合した後、亜鉛華を0.03g加えて30分混合した後、ビス(3−トリエトキシシリルプロピル)テトラスルフィドを30g加えて30分混合し、油浴を外して放冷後、混合物を得た。
含硫黄有機珪素化合物をビス(3−トリエトキシシリルプロピル)ジスルフィドに置き換えた以外は実施例1aと同様の操作を行い、混合物を得た。
珪酸を有する無機充填剤をカープレックス#1120(塩野義製薬(株)製)に置き換えた以外は実施例1aと同様の操作を行い、混合物を得た。
ステアリン酸、亜鉛華を加えない以外は実施例1aと同様の操作を行い、混合物を得た。
(1)上記実施例及び比較例で得られた混合物を、それぞれ所定のスチレンーブタジエンゴム(SBR)、ブタジエンゴム(BR)に添加してゴム配合とし、ゴム物性を測定することで各混合物の特性を評価した(表2中、実施例1A、2A、3A、および比較例1Aの「保存前」の欄)。
(2)また、比較試験として、混合物を用いる代わりに、純粋なビス(3−トリエトキシシリルプロピル)テトラスルフィド、ビス(3−トリエトキシシリルプロピル)ジスルフィドを相当量添加してゴム配合とし、同じく評価試験を行なった(表2中、比較例2および比較例3の「保存前」の欄)。
(3)更に、上記実施例1A、2A、3Aおよび比較例1Aで使用する混合物、並びに比較例2および比較例3で使用する純粋なビス(3−トリエトキシシリルプロピル)テトラスルフィド、ビス(3−トリエトキシシリルプロピル)ジスルフィドを35℃、相対湿度75%で3週間の恒温恒湿下で保存したものについても同様に特性を評価した(表2中、全ての実施例、比較例の「保存後」の欄)。
引張特性も同様のことが言え、表2-3に示す通り、実施例1A〜3Aでは、保存後若干の物性低下が認められるものの、比較例に対して格段の改善が見られる。
Claims (6)
- 無機充填剤(2)の付着水分が予め除去されたものであることを特徴とする請求項1に記載の混合物。
- 無機充填剤(2)の付着水分が予め除去されたものであることを特徴とする請求項4に記載の混合物の製法。
