In order to provide a rubber composition which is improved in dispersibility of silica in rubber compositions and can be improved as well in heat build-up and processability without causing increasing a viscosity of unvulcanized rubber and retarding a vulcanization rate, and a tire prepared by using the same, the rubber composition is endowed with a constitution in which at least one rubber component selected from natural rubber and/or diene base synthetic rubbers is compounded with a white filler and at least one of monoalkanolamides represented by the following Formula (I):
[in Formula (I) described above, R
1
represents an alkyl group or an alkenyl group having 1 to 13 carbon atoms, and the alkyl group and alkenyl group may be any of a linear type, a branched type and a cyclic type; and R
2
represents a hydroxyalkyl group or a hydroxyalkyl group having an oxyalkylene unit].
为了提供一种改善硅在橡胶配方中分散性的橡胶组合物,并且能够提高热积聚和加工性能,同时不会增加未硫化橡胶的粘度和延缓硫化速率,以及使用该组合物制备的轮胎,该橡胶组合物具有以下构成:将至少选择自天然橡胶和/或二烯基基合成橡胶中的一种橡胶组分与白色填料混合,并且至少混合一种由以下公式(I)表示的单醇酰胺之一:[在上述公式(I)中,R1表示具有1至13个碳原子的烷基或烯基基团,烷基和烯基基团可以是线性型、支链型和环型中的任何一种;R2表示羟基烷基或具有氧代烷基单元的羟基烷基]。
