The Influence of Selected Physico-Chemical Factors on Physico-Mechanical Properties of Studied Vulcanizates

Abstract

The focus of the presented study was set on the influence of physico-chemical factors on the physico-mechanical properties of the investigated vulcanizates containing carbon black filler substitution by mixing alternative fillers. Relating to the alternative partial substituents of fillers, the fine fractions of bentonite, polylactide, polypropylene and coffee grounds have been chosen. The prepared vulcanizates were exposed to various environment conditions which were based namely on DCSBD, plasma discharge (Diffuse Coplanar Surface Barrier Discharge), organic solvent and fungus extract of Piptoporus betulinus. The main objective of the study was to investigate the influence of the selected environment conditions on the physico -mechanical as well as dynamical and mechanical properties of the studied vulcanizates. The effect of chosen alternative fillers and physico-chemical factors on the physico-mechanical properties (elongation, tensile strength and hardness) was evaluated for the studied vulcanizates. Taking into account the chosen environment conditions, the viscoelastic behaviour of the prepared vulcanizates with alternative fillers and reference vulcanizate were evaluated on the basis of the results of the dynamical and mechanical analysis which was resulting from measurements. The measured results show that selected physico-chemical factors in combination with selected alternative fillers affect the physico-mechanical as well as dynamical and mechanical properties of the studied vulcanizates.

Effect of low-temperature plasma-treated bentonite on rubber compounds properties

“…The results show that the glass transition (T g ) for Ben_10 and Ben/P_10 compared to R, is shifted to higher values, which may be due to the higher crosslinking density and stronger polymer-filler interactions [25].…”
