Styrene butadiene rubber/clay nanocomposites for tire tread application

Abstract

Homogeneous and stable dispersion of layered silicates in their rubber nanocomposite is a matter of interest as it can significantly affect the material properties. Herein we propose a facile and easily industrialised approach for preparing highly dispersed montmorillonite (MMT)/rubber nanocomposites by the latex compounding method. Furthermore, an efficient way of enhancing the interlayer spaces of organically modified MMT ( f-MMT) with alkyl-ammonium chains while mixing the styrene butadiene rubber (SBR) is reported. The f-MMT embedded SBR matrix shows a remarkable improvement of the modulus and tensile strength even in the low loading rate, which is ascribed to the well dispersion of the f-MMT enhancing interfacial interaction with the rubber matrix. Furthermore, we manufactured the practical pneumatic tire using f-MMT/SBR nanocomposite with outstanding wear resistance, grip performance and low-rolling resistance for the green tire application, opening up enormous opportunities to prepare high-performance rubber composites for future engineering applications.

Characterization of eco-friendly processing aids for styrene butadiene rubber composites with silica

“…In the case of rubbers such as styrene butadiene rubber (SBR), which does not undergo strain-induced crystallization, various fillers have been used to improve the mechanical, thermal, and electrical properties as well as the processability and to reduce the cost of nearly all types of industrial rubbers. [1][2][3][4][5] Among them, 4,5 carbon black (CB) is considered as an important filler to enhance the hardness, tear strength, high tensile strength, and abrasion resistance of weak pure rubbers. However, in an effort to obtain the required characteristics and reduce the cost, CB decreases the rolling resistance and wet traction of the tire compounds.…”

Novel green composites from styrene butadiene rubber and palm oil derivatives for high performance tires

“…Rubbers have been used as viscoelastic polymers for applications in a wide range of industrial fields, especially the tire industry, by adding diverse fillers . Among the various fillers, carbon black (CB) is still widely used as a reinforcing filler to enhance abrasion and high tensile strength. However, CB also reduces wet traction and rolling resistance in tire tread compounds.…”

Effects of Zinc-Free Processing Aids on Silica-Reinforced Tread Compounds for Green Tires

“…Carbon black is an important filler that enhances the physical and mechanical properties, including tear strength, hardness, and abrasion resistance, of almost all industrial rubbers [1][2][3]. In recent years, however, "green tires" made with silica fillers instead of carbon black have exhibited greater abrasion resistance and wet grip, as well as lower rolling resistance [4][5][6].…”
