| 中文摘要: |
| 研究纳米四氧化三铁（Fe3O4）用量和粒径对天然橡胶胶料硫化特性和导热性能的影响。结果表明：用量相同时，纳米Fe3O4粒径越小，胶料的t90越短，纳米Fe3O4粒径大小对胶料的热导率影响不明显；粒径相同时，随着用量的增大，粒径为20 nm的纳米Fe3O4填充胶料的t90逐渐缩短，粒径为80和300 nm的纳米Fe3O4填充胶料的t90呈现先缩短后延长的趋势，胶料的热导率均得到大幅提升。 |
| 英文摘要: |
| The effects of addition level and particle size of nano Fe3O4 on curing behavior and thermal conduction of natural rubber compound were studied.The results showed that，when the addition level of nano Fe3O4 was same，the particle size was smaller，t90 of the compound was shorter，and the effect of the particle size on the thermal conduction was not obvious.When the particle size of nano Fe3O4 was same，t90 of the compound filled with 20 nm nano Fe3O4 was shortened with the increasing of the addition level of nano Fe3O4，t90 of the compound filled with 80 and 300 nm nano Fe3O4 tended to be shortened first and then lengthened，and the thermal conduction had all been greatly improved. |
