| Popis: | 106 Nowadays, it is a mainstream to use silica nanoparticles as fillers for tire rubber materials. Compared to the traditional carbon black (CB) as filler for tire rubber, silica nanoparticles have better effect on the mechanical properties of tire rubber for wider range of applications. But silica nanoparticles can not be dispersed well in rubber because the compatibility between silica and rubber is not good enough. To overcome this problem, a silane coupling agent with more than one alkoxy group at its both ends has been used for the modification. In addition, the amount of silane coupling agent is also needed to be considered. In this study, a suitable amount of coupling agent was found, and then a series of hybrid compounds were prepared by adding a tackifier and using different mixing process methods. The reactivity of the silane coupling agent, dispersibility of the silica nanoparticles and dynamic properties of tire rubbers were studied by using various techniques of Pyrolysis-GCMS, SAXS, TEM, mixing sequence and DMA. |
