| 摘 要： | 采用热重分析法(TGA)和差热分析法(DTA)研究了自然微生物凝固天然橡胶(N-NR)和淀粉微生物凝固天然橡胶(S-NR)在空气气氛中的热降解行为,为探索新的天然胶乳加工工艺提供科学依据。研究结果表明:(1)实验条件下,两种凝固方式的橡胶在空气气氛中的降解均为多步反应。(2)S-NR的抗氧化性能较N-NR好。

| Abstract: | To provide scientific reference to the coagulation process of NR latex,the thermooxidative degradation of nature rubber produced with starch coagulation(S-NR)and nature rubber produced with natural coagulation(N-NR)was studied by TGA-DTA under air atmosphere.The results showed that the thermal oxidative degradation of S-NR and N-NR was a multi-step reaction and the thermal stability of S-NR was greater than that of N-NR. |
