| 中文摘要: |
| 对某进口品牌的低滚动阻力315/70R22.5全钢载重子午线轮胎的胎面胶配方进行组分剖析和还原。结果表明：该轮胎的胎面胶配方的橡胶体系采用天然橡胶（NR）和乳聚丁苯橡胶（ESBR）并用（并用比为70/30），补强体系以白炭黑（45份）为主，结合少量炭黑（5份）。由此推断，以NR、ESBR和白炭黑为主要原材料，在湿法混炼加工条件下辅以适当的配合体系，可以获得性能优异的低滚动阻力胎面胶，从而使轮胎具有较低的滚动阻力。 |
| 英文摘要: |
| The composition of the tread compound formula for a low rolling resistance 315/70R22.5 all-steel truck and bus radial tire were analyzed and reverse restored.The results showed that，the tread compound formula of the tire adopted a rubber system consisting of a combination of natural rubber（NR） and emulsion styrene butadiene rubber（ESBR）（with a blending ratio of 70/30），and the reinforcement system was mainly composed of silica（45 phr），combined with a small amount of carbon black（5 phr）.It could be inferred that using NR，ESBR，and silica as the main raw materials，supplemented by appropriate blending systems under wet mixing processing conditions，could obtain high-performance compound with low rolling resistance tread，thereby enabling tires to had low rolling resistance. |
