| 中文摘要: |
| 通过雾化干燥法混炼制备纳米氧化锌（ZnO）/天然橡胶复合材料，并对其性能进行研究，同时与传统湿法混炼和传统干法混炼复合材料进行对比。结果表明：与采用传统湿法混炼和传统干法混炼相比，采用雾化干燥法混炼可使纳米ZnO在橡胶基体中分散较均匀，且无明显团聚，硫化胶的交联网络均匀，交联密度较大，物理性能、耐溶剂性能、耐老化性能和导热性能较好；采用雾化干燥法混炼可以减小胶料的纳米ZnO用量，缩短硫化时间，保证硫化胶的各项性能稳定。 |
| 英文摘要: |
| The nano zinc oxide（ZnO）/natural rubber（NR） composite was prepared by atomization drying method，and its properties were studied，and compared with the composites prepared by traditional wet mixing method and traditional dry mixing method.The results showed that，compared with the traditional wet method mixing and the traditional dry method mixing，the nano ZnO could be dispersed evenly in the rubber matrix by the atomization drying method mixing，and there was no obvious agglomeration.The crosslinking network of vulcanizate was uniform，the crosslinking density was larger，and the physical properties，solvent resistance，aging resistance and thermal conductivity were better.The atomization drying method mixing could reduce the amount of nano ZnO of compound，shorten curing time and ensure the stability of vulcanizate. |
