The invention provides a low-rolling-resistance tread rubber composition, a preparation method thereof and a new energy tire, and relates to the technical field of rubber composite materials. The low-rolling-resistance tread rubber composition comprises 60-70 parts of natural rubber, 50-60 parts of vinyl polybutadiene rubber, 40-50 parts of carbon black, 10-20 parts of a modified heat-conducting filler, 10-20 parts of a functional auxiliary agent, 2-7 parts of a softening agent, 4-8 parts of an active agent, 1-3 parts of a vulcanizing agent, 1-3 parts of an accelerant and 1-3 parts of an anti-aging agent. The tread rubber of the tire contains the modified heat-conducting filler and the functional additive, and the modified heat-conducting filler and the functional additive are matched with other components, so that the binding force between polymers and the filler and between the polymers can be effectively improved, the rolling resistance and heat generation of the tire are reduced, and the endurance mileage of a new energy automobile can be increased.
本发明提供了一种低滚阻胎面胶组合物及其制备方法和新能源轮胎,涉及橡胶复合材料技术领域。低滚阻胎面胶组合物包括:天然橡胶60‑70份、乙烯基聚丁二烯橡胶50‑60份、炭黑40‑50份、改性导热填料10‑20份、功能性助剂10‑20份、软化剂2‑7份、活性剂4‑8份、硫化剂1‑3份、促进剂1‑3份以及防老剂1‑3份。该轮胎的胎面胶中含有改性导热填料和功能性助剂,二者与其他组分相配合,可有效提高聚合物与填料、聚合物与聚合物之间结合力,降低轮胎滚动阻力和生热,能够提高新能源汽车的续航里程。
