摘 要：The dynamic viscoelastic properties of solution polymerized styrene-butadiene (SSBR) filled with different proportion of carbon black and silica were studied by using the rubber processing analyzer (RPA2000) and DMA under different scanning conditions.The results indicated that in the first strain sweeping process,the storage modulus (G') reduced gradually with the increase of ratio of carbon black,and the function of coupling agent (Si69) decreased.During the secondary strain sweeping process,it was found that with the increase of sweeping time interval,the stress softening phenomenon abates.On the other hand,through three strain sweeping,it was considered that the effect of Payne was not caused only by the factor of filler-net.
