纳米ZnO对天然橡胶交联反应和热稳定性的影响

Common zinc oxide and nano-zinc oxide were used to composite natural rubber separately. Their vulcanization profiles and TGA curves showed the composite of natural rubber with nano-znic oxide possessed higher effective crosslinking ratio, then, the improved thermal stability and mechanical properties.
