Styrene-Butadiene Rubber/Modified Ground Tire Rubber Blends Co-Vulcanization: Effect of Accelerator Type

Abstract

Ground tire rubber was thermo-mechanically modified with using a co-rotating twin screw extruder. Modification of GTR was conducted in autothermal conditions. Styrene-butadiene rubber and modified ground tire rubber blends were prepared via two-roll milling. Obtained compounds were cured with conventional system (sulfur/vulcanization accelerator ratio was 2:1). During this research three commonly vulcanization accelerators (MBT, TBBS, TMTD) were used. Curing characteristics, static mechanical properties (tensile strength, elongation at break, hardness, resilience), dynamic mechanical properties, swelling degree and thermal properties of obtained SBR/mGTR blends were determined. SBR/modified GTR blends with higher amount of modified GTR shown improvement in tensile strength, on the other hand vulcanization accelerator type had strong influence on curing parameters, tensile strength, elongation at break, swelling degree and glass transition temperature. The best curing and mechanical properties were estimated for SBR/mGTR blend with 50 phr mGTR cured with TMTD accelerator.
