摘要：
The natural rubber/nano-CaCO3 composites were prepared with nano-CaCO3 modified using epoxidized natural rubber latex (ENRL) and the morphology and thermal stability were analyzed using scanning electron microscopy and thermal gravimetric analysis. As compared to the control, the initial temperatures of composites from unmodified nano-CaCO3 are almost unchanged, while those from the ENRL-modified nano-CaCO3 increase obviously. And the initial temperature of the composite rises from 356.29°C to about 362.06°C with the loading of 4% ENRL-modified nano-CaCO3. The results show that strong interaction exists between ENRL-modified nano-CaCO3 particles and rubber matrix, leading to the improvement of thermal stability of composite.
