| 中文摘要: |
| 研究普通蜡、高温蜡以及抗喷霜蜡对轮胎胎侧胶性能的影响，重点研究3种蜡的抗喷霜效果，同时探讨新型胺类防老剂对防老剂4020的替代效果。结果表明：不同类型防护蜡对胎侧胶的硫化特性和物理性能影响较小；抗喷霜蜡的臭氧防护效果优异，形成的表面蜡膜致密、厚薄均匀、平整光滑，对橡胶的粘附力好，具有优异的抗喷霜效果，有效提升了轮胎的外观质量；在轮胎工业中，使用新型胺类防老剂替代防老剂4020，可以有效改善橡胶外观发红变色现象，具有广泛的使用价值。 |
| 英文摘要: |
| The effects of ordinary wax，high-temperature wax and anti-blooming wax on the properties of tire sidewall compounds were studied，with a focus on the anti-blooming effects of the three waxes.At the same time，the substitution effect of a new antioxidant on antioxidant 4020 was discussed.The results showed that different types of protective waxes had little effect on the vulcanization characteristics and physical properties of sidewall compound.The anti-blooming wax had excellent ozonization protection effect，the formed surface wax film was dense，uniform in thickness，smooth and even，with good adhesion to rubber and small gaps，the anti-blooming wax had excellent anti-blooming effect，effectively improved the appearance quality of tires.In the tire industry，the use of a new antioxidant to replace antioxidant 4020 could effectively improve the red discoloration of rubber appearance，had wide application value. |
