Abstract :

In this research, the effect of silane-modified carbon black and nano-silica hybrid fillers on the curing and dynamic properties of butyl rubber (IIR) nano compounds was studied. Results revealed that the modification process influenced curing properties. The ∆Torque and Maximum torque (Mh) increased to the value of 3.4 dN.m and 4.3 dN.m after silane modification CB, which led to higher cross-link density (163.1 mol/m3). Scanning electron microscopy (SEM) analysis indicated better dispersion of the modified CB in IIR nano compounds, which led to better properties and performance. The dynamic-mechanical-thermal analysis (DMTA) showed that modified CB reduced rolling resistance and improved ice grip potential. Overall, selecting modification approaches is crucial for achieving optimal results in the performance and application of IIR.
