A rubber composition which comprises (A) at least one rubber component selected from the group consisting of natural rubber and diene synthetic rubbers, (B) an inorganic filler comprising at least one filler selected from silica and silicates as the main component and (C) an addition salt of an amine represented by general formula (I):
wherein R1 represents a C8 to C24 alkyl group, an aryl group or an aralkyl group, R2 and R3 represent a hydrogen atom, a C1 to C12 alkyl group, an aryl group, an aralkyl group or a hydroxyalkyl group and R4 represents a C6 to C24 alkyl or alkenyl group, an aryl group or an aralkyl group; and a pneumatic tire produced by using the rubber composition.
Fuel consumption of a pneumatic tire is decreased and workability and productivity in vulcanization in the production of a pneumatic tire are improved by using the rubber composition.
一种橡胶组合物,包括(A)至少一种选自天然橡胶和二烯合成橡胶的橡胶组分,(B)至少一种选自二氧化硅和硅酸盐的无机填料作为主要组分,以及(C)通式(I)代表的胺的加成盐:
其中 R1 代表 C8 至 C24 烷基、芳基或芳烷基,R2 和 R3 代表氢原子、C1 至 C12 烷基、芳基、芳烷基或羟烷基,R4 代表 C6 至 C24 烷基或烯基、芳基或芳烷基;以及使用该橡胶组合物生产的充气轮胎。
使用该橡胶组合物可降低充气轮胎的燃料消耗,提高生产充气轮胎时硫化的作业性和生产率。
