| 中文摘要: |
| 应用纳米氧化锌对轻型载重斜交轮胎胎面胶配方进行优化设计。试验结果表明，通过应用纳米氧化锌，调整生胶比例和减小炭黑用量，可以改善胎面胶挤出工艺性能，显著降低胎面胶的生热和压缩永久变形，提高成品轮胎胎面胶的300%定伸应力和拉伸强度，使轮胎肩空退赔率大幅度降低。 |
| 英文摘要: |
| The tread formula of LT tire was optimized by using nano-zinc oxide.The test results showed that the extrudability of tread compound improved,the heat build-up and compression set of tread decreased significantly,the modulus at 300% and tensile strength of the tread in finished tire increased,and the compensation rate of tire caused by shoulder seperation reduced remarkably by using nano-zinc oxide,adjusting raw rubber content and blending ratio,and decreasing additional level of carbon black. |
