Abstract
【解決手段】(A)ジエン系ゴムを30重量部以上含むゴム成分100重量部、(B)ジチオサリチル酸0.1〜10重量部及び(C)有機金属塩を金属含有量として0.05〜0.5重量部含むゴム組成物並びにそれを用いた空気入りタイヤ。
【選択図】なし
Description
サンプルの調製
表Iに示す配合において、加硫促進剤と硫黄を除く成分を1.5リットルの密閉型ミキサーで7.5分間混練してマスターバッチを得た。このマスターバッチに加硫促進剤と硫黄をオープンロールで混練し、ゴム組成物を得た。
引張り試験
100%モジュラス(M100)、破断強度(TB)及び破断伸び(EB)はJIS K6251に準拠して測定した。
ワイヤ接着性:ASTM(D1871)に準拠してプラスメッキワイヤーと未加硫ゴムをメーキングして引抜試験を行い、引抜力(N)とゴム付着率(%)を得た。引抜力とゴム付着率が大きいほどゴムとワイヤの接着性が良いことを示す。
老化後の接着性:老化(100℃・48時間)後の試験片を用いて引抜試験を行い、引抜力(N)とゴム付着率(%)でゴムとワイヤの接着性を評価した。
プレッシャークッカー試験後の接着性:プレッシャークッカー試験機に130℃,95%RH,48時間の条件下で試験した試験片を用いて引抜試験を行い、引抜力(N)とゴム付着性(%)でゴムとワイヤの接着性を評価した。
