IntroductionSilica (SiO2) is one of the important reinforcing fillers in rub-ber industry. Since the beginning of the 90s of last century, silicawas increasingly used in tires as the rise and development of “greentire”. The application of highly dispersible silica together with somespecial rubbers such as solution polymerized styrene-butadienerubber (SSBR) in tires leads to the best improvement of rolling resis-tance and wet traction without any compromises in tread wear[1]. The silica in green tire was usually used together with somesilane coupling agents such as bis(triethoxysilylpropyl)tetrasulfane(TESPT).It is well known that epoxidized natural rubber (ENR) is amodified rubber prepared by the epoxidized reaction of naturalrubber (NR) in peracid conditions [2,3]. ENR possesses some newproperties except the normal characteristics of NR, such as oil resis-tance, gas tightness [4,5], low rolling resistance and high wet skidresistance. These properties are useful in tires and other rubberproducts. It was shown that the comprehensive properties of silica-reinforced vulcanizate can be substantially improved by addingENR as a compatilizer [6]. In addition, ENR can be applied in com-posites reinforced with other fillers, such as organoclay [7,8] and
