Provided are a rubber composition for tire containing raw material rubber and cellulose whiskers, and a tire produced from the same composition and having excellent general properties. Since the rubber composition for tire contains cellulose whiskers having superior reinforcing properties than rubber reinforcing materials, the rubber composition for tire can provide a tire having markedly enhanced properties compared to tires using the conventional rubber reinforcing materials. Also, when cellulose whiskers are applied to the rubber composition for tire, the content of the conventional rubber reinforcing materials can be reduced. As a result, the elongation ratio and low-fuel consumption performance that have been considered poor due to the use of conventional rubber reinforcing materials can be improved to a superior level, and a lightweight tire can be provided.
本发明提供了一种含有原料橡胶和
纤维素晶须的轮胎橡胶组合物,以及用该组合物生产的轮胎,该轮胎具有优异的一般性能。由于轮胎用橡胶组合物含有
纤维素晶须,其补强性能优于橡胶补强材料,因此与使用传统橡胶补强材料的轮胎相比,轮胎用橡胶组合物可提供性能显著增强的轮胎。此外,将
纤维素晶须应用于轮胎橡胶组合物时,可减少传统橡胶补强材料的含量。因此,由于使用传统橡胶补强材料而被认为较差的伸长率和低油耗性能可提高到更优越的
水平,并可提供轻质轮胎。
