TL;DR: Fixed bed experiments and gas chromatography analysis identify the main gas products of the three rubbers (NR, SBR, NR-SBR) as H2, CH4 and CH2=CH2 and the change of yield caused by the increase of SBR content are consistent with the simulation results.

TL;DR: In this article, the reinforcing effect of high structure carbon black (HSCB) and multi-walled carbon nanotubes (MWCNTs) on natural rubber/styrene-butadiene rubber blend processed using mechanical mixing was comparatively investigated.
Abstract: The reinforcing effect of high structure carbon black (HSCB) and multi-walled carbon nanotubes (MWCNTs) on natural rubber/styrene-butadiene rubber blend processed using mechanical mixing was comparatively investigated. In-depth analysis by dynamic mechanical analysis, the Eggers − Schummer model and Medalia's relationship showed that HSCB aggregates provided large internal pores leading to significant immobilized macromolecules in filled rubber. Additionally, a tubular immobilized rubber layer with a thickness of 8 nm was estimated for the rubber/MWCNT system based on dynamic mechanical analysis data. The mechanical performance of the HSCB filled blend was higher than that of the MWCNT filled blend at the same loading which was correlated to its higher bound rubber content. Both bound rubber content and filler anisotropy were found to govern the overall mechanical properties of rubber/MWCNT composites. Stress softening was correlated with rupture energy suggesting hysteretic failure mechanisms in both MWCNT and HSCB filled rubbers. © 2015 Society of Chemical Industry

TL;DR: In this article, a rubber component for a conveyor belt consisting of butadiene rubber, carbon black, sulfur, and a vulcanization accelerator was presented. Butadiene and styrene butadienes rubber were used to reduce power consumption at low temperatures when the belt was formed.
Abstract: The purpose of the present invention is to provide a rubber composition for a conveyor belt, the rubber composition allowing significant reductions in power consumption at low temperatures when the conveyor belt is formed, and also to provide a conveyor belt. The rubber composition for a conveyor belt of the present invention comprises: a rubber component containing butadiene rubber and/or styrene butadiene rubber, carbon black, sulfur, and a vulcanization accelerator; the glass transition temperature of the butadiene rubber and the styrene butadiene rubber being -65°C or lower; the nitrogen adsorption specific surface area of the carbon black being 90 m2/g or less; the total content of the butadiene rubber and the styrene butadiene rubber being 50% by mass or greater relative to the content of the rubber component; the content of the carbon black being from 30 to 50 parts by mass per 100 parts by mass of the rubber component; and the mass ratio (sulfur/vulcanization accelerator) of the content of the sulfur to the content of the vulcanization accelerator being 1.5 or less.

TL;DR: In this article, a kinetic model which accounts for the effects of scission of polymeric chain at any time was proposed to describe the thermal degradation of styrene-butadiene rubber (SBR).
Abstract: The kinetics of thermal degradation of styrene-butadiene rubber (SBR) was studied by conventional thermo-gravimetric technique with various heating rates under nitrogen. A kinetic model which accounts for the effects of scission of polymeric chain at any time was proposed to describe the thermal degradation of SBR. Results showed that the contribution of the thermal degradation of zero-order reaction is greater than that of first-order and second-order reactions. The activation energy of the thermal degradation of SBR was calculated to be 172 kJ/mol using the Arrhenius equation.
