This invention provides a modified natural rubber producible at a lower cost than the conventional techniques and capable of improving the low loss factor, wear resistance and fracture characteristics of the rubber composition using the modified natural rubber as the rubber component in the rubber composition, and a method for producing the modified natural rubber. This invention provides a modified natural rubber formed by adding a hydrazide compound having a polar group to at least one natural rubber raw material selected from the group consisting of a natural rubber, a coagulated natural rubber latex and a natural rubber cup lump, a rubber composition using the modified natural rubber, and a tire using the rubber composition in any tire member.
本发明提供了一种改性天然橡胶,其生产成本低于传统技术,并且能够改善橡胶组合物的低损耗因子、耐磨性和断裂特性,橡胶组合物中使用改性天然橡胶作为橡胶成分,本发明还提供了一种生产改性天然橡胶的方法。本发明提供了一种通过向至少一种天然橡胶原料添加具有极性基团的酰肼化合物而形成的改性天然橡胶,该天然橡胶原料选自天然橡胶、凝固天然橡胶胶乳和天然橡胶杯状胶块组成的组,还提供了一种使用改性天然橡胶的橡胶组合物,以及一种在任何轮胎部件中使用该橡胶组合物的轮胎。
