The invention relates to the technical field of tires, and discloses tread rubber with an asymmetric rubber material structure, a preparation method and a tire adopting the tread rubber. The tread rubber provided by the invention comprises five tread rubber areas, namely first tread rubber, second tread rubber, third tread rubber, fourth tread rubber and fifth tread rubber in sequence, the first tread rubber adopts a rubber composition A with low abrasion and high road holding force, the second tread rubber and the third tread rubber adopt a rubber composition B with low rolling resistance, and the fifth tread rubber adopts a rubber composition B with low rolling resistance. And the fourth tread rubber and the fifth tread rubber are made of rubber compositions C with high wet grip and low noise. Through division and optimization of the structure of the tread rubber, rubber materials with different performance emphasis are adopted in different areas, the combination form of the tread rubber can balance and control the rolling resistance performance, the wear resistance performance, the braking performance and the control performance of the tire, and the tire with balanced rolling resistance, wear resistance, braking performance, control performance and comfort can be provided after vulcanization. And the optimization and balance of the tire performance are realized.

    本发明涉及轮胎技术领域,公开了一种非对称胶料结构的胎面型胶、制备方法和采用该胎面型胶的轮胎。本发明提供的胎面型胶包括五个胎面胶区,依次为第一胎面胶、第二胎面胶、第三胎面胶、第四胎面胶、第五胎面胶,第一胎面胶采用低磨耗、高抓地力的橡胶组合物A,第二胎面胶和第三胎面胶采用低滚阻的橡胶组合物B,第四胎面胶和第五胎面胶采用高湿抓、低噪音的橡胶组合物C。通过对胎面胶结构的分工和优化,不同区域采用不同性能侧重点的胶料,该胎面胶组合形式可平衡控制轮胎的滚阻性能、耐磨性能、制动性能和操控性能,硫化后可以提供滚阻、耐磨、制动性能、操控性能、舒适度均衡的轮胎,实现了轮胎性能的优化与平衡。
