摘　　要：将微波辐射应用于胶清橡胶的凝固,对比微波辐射凝固胶清橡胶(NR-s-m)与硫酸凝固胶清橡胶(NR-s-a)的性能差异。结果表明,理化性能方面,NR-s-m的灰分含量、杂质含量、挥发物含量以及氮含量较高,塑性初值、抗氧指数和门尼粘度也更高;力学性能方面,NR-s-m硫化胶拉伸强度、扯断伸长率、撕裂强度和硬度均比NR-s-a的高;硫化特性方面,NR-s-m比NR-s-a的硫化速度快,并随微波辐射功率的增大而加快。Microwave radiation was used to coagulate skim rubber.Differences between properties of natural rubber coagulated by microwave radiation（NR-s-m） and that of natural rubber coagulated by sulfuric acid（NR-s-a） were studied.The results showed that,as to physical and chemical properties,ash content,impurities content,volatile content and nitrogen content of NR-s-m are higher than NR-s-a,initial plasticity,antioxidant index and Mooney viscosity of NR-s-m are also higher than NR-s-a.As to mechanical properties,tensile strength,elongation at break,tear strength and hardness of NR-s-m are much higher than NR-s-a.To curing behaviors,the curing rate of NR-s-m which increased as power of microwave radiation increased is higher than NR-s-a.
