Influence of Fillers and Ionic Liquids on the Crosslinking and Performance of Natural Rubber Biocomposites

This work concerns the effect of fillers and ionic liquids on cure characteristics natural rubber (NR) compounds, as well mechanical thermal properties vulcanizates. Three types white filler were applied, such cellulose, nanosized silica hydrotalcite, to modify performance NR composites. Additionally, (ILs) with bromide anion different cations, i.e., 1-butyl-3-methylimidazolium (Bmi) 1-butyl-3-methylpyrrolidinium (Bmpyr), used improve compounds functional The type structure ILs proved affect rheometric Owing adsorption curatives onto surface, reduced activity crosslinking system, prolonging optimal vulcanization time reducing degree elastomer. However, silica-filled exhibited highest stability. Hydrotalcite increased crosslink density and, consequently, vulcanizates, but deteriorated their beneficially influenced particularly those filled silica. Cellulose did not significantly vulcanizates compared unfilled elastomer, tensile strength. On other hand, cellulose improved stability considerably alter damping
