| 摘要 |
We provide a method for producing a rubber composition that includes a rubber component (A) including natural rubber, at least one filler (B) selected from an inorganic filler and carbon black, and a hydrazide compound (C), the method comprising compounding in an optional preliminary compounding stage and a plurality of compounding stages, and adding the hydrazide compound (C) and kneading in the preliminary compounding stage and/or a first compounding stage, the hydrazide compound (C) being represented by general formula (I): R—CONHNH2, where R represents an alkyl group having from 1 to 30 carbon atoms, a cycloalkyl group having from 3 to 30 carbon atoms, or an aryl group. We also provide a rubber composition produced with this method. |
