  Abstract

To simultaneously improve processing performances of rubber composites and avoid additive-blooming problem, the concept of 쐓upported rubber additives was introduced and reactive processing additive oleic acid (OA) was chemically immobilized onto the surface of silica to obtain silica-supported processing additive (SiO2-s-OA). In this study, SiO2-s-OA was uniformly dispersed into styrene-butadiene rubber (SBR) and gained improved interfacial interaction with rubber matrix due to its good compatibility and the reaction during vulcanization. Consequently, SBR compounds with SiO2-s-OA possessed lower vulcanizing torque and viscosity under high shear frequency, showing improved processing performance. Moreover, the tensile modulus and strength of SBR/SiO2-s-OA could be enhanced by as much as 88.40 % and 11.44 % compared to SBR/SiO2, respectively, which is also higher than SBR/m-SiO2. Taken together, these results indicate that this method for the surface treatment of silica to prepare supported rubber additives may be extended for other nanofillers and rubber additives, which has better processing performance and improved mechanical property simultaneously.
