Effect of Organoclay Content on Mechanical and Melt Viscoelastic Properties of NR/GTR Blends

Reusing or recycling of Ground Rubber Tire (GTR) because of environment protection is an important topic for the researchers in recent years [1,2]. But due to the lack ofreaction sites on GTR the incorporation of GTR into the polymer chains is very poor and this impairs the mechanicaland viscoelastic properties of the blends [3,4]. So increasingthe compatibility between polymer matrix and GTR particles needs adding of a compatibilizer to increase the chemicaladhesion or reclaiming agent to break down the particles and enhances physical compatibility [1,2].In this study, GTR was used in a rubber comound based onnatural rubber (NR) in presence of organoclay and a devulcanizing agent. Effect of different organoclay content onmechanical and rheological properties of the GTR/NR blends has been studied
