| 中文摘要: |
| 研究防老剂STMQ的性能优势及其在轮胎中的应用。结果表明：与防老剂TMQ相比，防老剂STMQ具有更高的有效体含量和热稳定性及更好的结晶性；添加防老剂STMQ的胶料具有更小的挥发性有机物挥发量和更小的气味；防老剂STMQ对胶料变色的影响更小；在轮胎胶料中用防老剂STMQ减量替代防老剂TMQ仍可以达到优良的老化防护性能，同时保证胶料物理性能相当。 |
| 英文摘要: |
| The property advantages of antioxidant STMQ and its application in tire were studied.The result showed that，compared with antioxidant TMQ，antioxidant STMQ had higher effective impurity content，thermal stability and better crystallinity.The compound with antioxidant STMQ had less volatilization and smell than the compound with antioxidant TMQ.Antioxidant STMQ had less effect on the discoloration of the compound than antioxidant TMQ.Using antioxidant STMQ in reduced amount replace of antioxidant TMQ with in tire compound could also achieve excellent anti-aging protection effect，at the same time，ensure that the physical properties of the compound were equivalent. |
