| Abstract: | Attapulgite(AT) reinforced natural rubber(NR) nanocomposites were prepared by mechanical compounding.The microstructures,mechanical properties and curing characteristics of the nanocomposites were investigated.The reinforcement mechanism of AT in NR was clarified.The results show that the modified AT exhibited outstanding reinforcement due to its homogeneous dispersion in the NR matrix and the strong polymer-filler interactions.AT needles not only act as crosslink points during the vulcanization,but also or... |
