| 中文摘要: |
| 研究间接法氧化锌（氧化锌A）和纳米氧化锌（氧化锌B，C和D）微观结构和用量对天然橡胶（NR）性能的影响。结果表明：与间接法氧化锌相比，相同用量下，纳米氧化锌硫化胶的生热和滞后损失较低，3种纳米氧化锌均可代替间接法氧化锌；纳米氧化锌用量减半，氧化锌C和D硫化胶的生热较低，耐磨性能较好，氧化锌C硫化胶的滞后损失较低，使用3种纳米氧化锌均可达到锌减量的目的。 |
| 英文摘要: |
| The effects of microstructure and the addition amount of indirect zinc oxide（zinc oxide A）and nano-zinc oxide（zinc oxide B，C and D） on the properties of natural rubber（NR） compound were studied. The results showed that the heat build-up and hysteresis loss of nano-zinc oxide filled vulcanziates were lower than that of indirect zinc oxide filled vulcanziates. All three kinds of nano-zinc oxide could replace the indirect zinc oxide. When the addition level of nano-zinc oxide was reduced by half，the heat build-up of the vulcanizates with zinc oxide C or D were lower，the wear resistance of the vulcanizates with zinc oxide C or D was better，the hysteresis loss of the vulcanizates with zinc oxide C was lower. Use of nano-zinc oxide could effectively reduce the addition level of zinc oxide. |
