| 中文摘要: |
| 试验研究优化炼胶工艺对半钢子午线轮胎胎面气孔率的影响。结果表明，与传统胎面胶三段混炼工艺相比，四段混炼工艺生产的胎面胶料的炭黑分散度等级和分散性指数均较高，胶料的流动性提高，物理性能提升，可降低挤出胎面的断面气孔率，最终提升成品轮胎的胎面稳定性、外观质量及耐磨性能。 |
| 英文摘要: |
| The effect of optimized mixing process on the porosity in tread of steel-belted radial tire was experimentally investigated.The results showed that，compared with conventional three-step mixing process，the carbon black dispersion status and dispersion index of the tread compound with four-step mixing process were higher，the flowability of the compound and the physical properties of the vulcanizates increased，the porosity in tread cross-section was reduced，and the tread stability，appearance quality and wear resistance of the finished tire were improved. |
