| 摘 要： | 采用胶乳共混法制备了TiO2/天然橡胶纳米复合材料。DMA分析结果表明，TiO2/天然橡胶复合材料的玻璃化转变温度和活化能高于纯天然橡胶。根据热分解动力学模型，求得硫化橡胶空白样，掺入TiO2 0.1%、0.5%、10%、20%的样品的分解活化能分别为229.699、231.085、201.727、219.107、208.249 kJ/mol，动力学模型指前因子分别为5.07×10^17、8.46×10^17、2.94×10^15、8.03×10^16、1.04×10^16/s。

| Abstract: | The TiO2/natural rubber nano-composite material was prepared by latex blending method.The results of DMA analysis showed that the glass transition temperature and activation energy of TiO2/natural rubber composite material were all higher than those of pure natural rubber.According to the dynamic model of thermal decomposition,the decomposition activation energy of blank sample(vulcanized rubber)and the samples which contained TiO2 with 0.1%,0.5%,1.0%,2.0% were 229.699,231.085,201.727,219.107,208.249 kJ/mol... |
