Abstract :

The influence of nano-silica on the properties of Skim rubber composites was investigated. When the nano-silica particles were using method of using blends of latex into rubber, the 300% extension stress and aging properties increased evidently with increasing nano-silica amount from 5 to 20 phr. Scanning electron microscopy (SEM) observations of the Tensile fracture surface showed that some apparent nano-silica particles were left on the surface of the composite, which strongly suggested that the nanosilicon particles were small and that interfacial adhesion between the nano-silica and rubber was relatively high. To improve the dispersion of the nano-silica in the rubber matrix, nano-silica/Skim rubber master batches were prepared by a latex compounding method. With nano-silica/Skim rubber master batches, no holes of nano-silica particles were left on the surface, this suggested that the interfacial strength was improved because of the fine dispersion of nano-silica, Mechanical properties and aging properties have a significantly improved. The composites exhibits excellent thermal performance, glass transition temperature (Tg) increased according to thermal properties test. Under different strain, Curves of Gâ�� versus and tan�´ are different, more precisely, Gâ�� decreased and tan�´ increased with increasing silica loading, while Under different temperature, Showing the opposite phenomenon.
