| 中文摘要: |
| 根据无机配合剂在橡胶中的分散形态，研究纳米氧化锌在橡胶中的作用机理及其对胶料性能的影响。在硫化过程中氧化锌作为活性剂与有机促进剂、硬脂酸、硫黄等的反应发生在氧化锌粒子的表面。以纳米氧化锌等量替代普通间接法氧化锌，可提高硫化胶的300%定伸应力和耐磨性，减小压缩永久变形，降低压缩疲劳温升；以纳米氧化锌减量50%替代间接法氧化锌，仍可保证硫化胶的性能要求。 |
| 英文摘要: |
| The action mechanism of nano-zinc oxide in rubber and its effect on the properties of rubber compound were investigated.The results showed that the zinc oxide was used as activator to react with organic accelerators,stearic acid,sulfur ect.on its particle surface during vulcanization;the modulus at 300% and abrasion resistance of vulcanizate increased,and the compression set and compression fatigue temperature-rise decreased by using nano-zinc oxide instead of conventional indirect zinc oxide in equal weight;and the desired properties of vulcanizate could be obtained by using nano-zinc oxide in half weight instead of indirect zinc oxide. |
