The invention belongs to the technical field of rubber, and particularly relates to sidewall rubber as well as a preparation method and application thereof. The sidewall rubber material comprises matrix rubber, a filler, an active agent, an anti-aging agent, resin and a vulcanizing agent, the matrix rubber comprises natural rubber and butadiene rubber, the butadiene rubber is rare earth modified butadiene rubber, the tail end of the butadiene rubber is provided with an active group, on one hand, the modified butadiene rubber is good in molecular chain flexibility and heat resistance, and on the other hand, the modified butadiene rubber is not prone to falling off; on the other hand, the butadiene rubber molecular chain with the active group promotes the dispersion of the filler, and the filler with good dispersity can reduce the free movement of the polymer molecular chain in the sidewall rubber material, so that the hysteresis energy loss of the sidewall rubber material is reduced, and the service life of the sidewall rubber material is prolonged. And the endurance mileage of a new energy automobile and a traditional fuel automobile is improved.
本申请属于橡胶技术领域,尤其涉及一种胎侧胶料及其制备方法和应用。本申请提供的一种胎侧胶料及包括基体橡胶、填料、活性剂、防老剂、树脂、硫化剂,所述基体橡胶包括天然橡胶和顺丁橡胶,所述顺丁橡胶为稀土改性顺丁橡胶,其末端具有活性基团,改性的顺丁橡胶一方面由于分子链柔顺性好,耐热性能好,提高了胎侧胶料的屈挠性能和耐高温性能,另一方面带有活性基团的顺丁橡胶分子链促进了填料的分散,分散度好的填料可以减少胎侧胶料中聚合物分子链的自由活动,从而降低了胎侧胶料的滞后能量损失,提升了新能源汽车以及传统燃油汽车的续航里程。
