The invention provides a rubber composition prepared by mixing, per 100 parts by mass of the rubber component comprising at least 50% by mass of a diene-based rubber, from 20 to 150 parts by mass of a filler, and from 0.05 to 30 parts by mass of a compound A which has a specific amidine structure and has a functional group reactive with the diene-based rubber. The rubber composition improves both a high elastic modulus and a low tan δ. The invention also provides a pneumatic tire using the rubber composition.
本发明提供了一种橡胶组合物,其通过混合制备而成,每100质量部的橡胶组分中包括至少50质量部的二烯基橡胶、从20到150质量部的填料和从0.05到30质量部的化合物A,化合物A具有特定的酰胺结构并具有与二烯基橡胶反应的功能基团。该橡胶组合物提高了高弹性模量和低tanδ。本发明还提供了一种使用该橡胶组合物的充气轮胎。
