Abstract
【解決手段】天然ゴム及び合成ジエン系ゴムの少なくとも1種のゴム成分と、アミン系老化防止剤と、シリカゲルとを含有し、かつ上記アミン系老化防止剤の含有量が上記ゴム成分100質量部に対して3〜10質量部であることを特徴とするゴム組成物を提供する。
【選択図】なし
Description
本発明のゴム組成物は、上述のように、天然ゴム及び合成ジエン系ゴムから選ばれた少なくとも1種のゴム成分と、アミン系老化防止剤と、シリカゲルとを含有してなるものである。
下記、表1に示す配合成分を混練し、加硫して実施例1〜7及び比較例1〜3の10種のゴム組成物を得た。得られた各ゴム組成物につき、耐オゾン性及び接着性を下記の通り評価した。結果を表1に示す。
JIS K6259(1993)に従い、40℃、50pphm、0−20%伸張の条件で動的オゾン劣化試験を行い、24hr後、100hr後、200hr後の亀裂の状態をJIS K6259に規定の基準に従って評価した。
接着性
JIS K6256(1999)に従い、鋼材及びアルミ材に対する剥離試験を行って接着性を評価した。良否判定は、ゴム凝集破壊が生じたものを○(良)、それ以外の破壊が生じたものは×(否)とした。なお、表1中の「熱老化後」の値は、70℃に1000hr放置した後の結果である。
