Vulcanization and reinforcement are critical factors in governing the ultimate practical applications of elastomer composites. Here we achieved a simultaneous improvement of curing and mechanical properties of elastomer composites by the incorporation of a functionalized halloysite nanotubes–silica hybrid (HS-s-M). Typically, HS-s-M was synthesized by 2-mercapto benzothiazole (M) immobilized on the surface of halloysite nanotubes–silica hybrid (HS). It was found that the HS-s-M uniformly dispersed in the styrene-butadiene rubber (SBR) matrix, offering more opportunity for M molecules to communicate with rubber. In addition, the physical loss of accelerator M from migration and volatilization was efficiently suspended. Therefore, SBR/HS-s-M composites showed a lower curing activation energy and a higher crosslinking density than SBR/HS composites. Moreover, a stronger interfacial interaction between HS-s-M and SBR was formed by the cross-linking reaction, giving a positive contribution to the eventual mechanical properties. The possible vulcanization and reinforcement mechanisms of SBR/HS-s-M composites were also analyzed in detail.

Effect Of Surface

Starch/Styrene Butadiene Rubber (SBR) biocomposites were prepared by directly blending of starch and SBR on a two-roll miller. Two types of starch: pure starch and modified starch (M-starch) were used as rubber fillers. M-starch were synthesized by grafting of methyl methacrylate (MMA) monomer onto starch backbone using ceric ammonium nitrate-initiated radical polymerization. Coupling agent styrene-g-(maleic anhydride) (SMA) was used to further improve the interfacial interaction between the filler and rubber matrix. The morphology and mechanical properties of unmodified starch/SBR and M-starch/SBR biocomposites with SMA content of 0, 1, 3, and 5 phr were investigated. SEM observations showed the particle size of M-starch decreased and their dispersion in the SBR matrix significantly improved than unmodified starch. Mechanical properties of M-starch/SBR biocomposites were superior than those of unmodified starch/SBR biocomposites.

Abstract Nanocellulose was extracted from bagasse (bagasse nanocellulose, BNC) by hydrolysis with alkali and acid, then grafted by maleic anhydride (MAH) and styrene (St). The modified nanocellulose (BMS) was further investigated to partially replace carbon black (CB) in St butadiene rubber (SBR) composites via coagulation to prepare SBR/BMS/CB composites. Through the comparison of the vulcanization characteristics, processing properties, mechanical properties, and dynamic mechanical performance of them, BMS proved to be more efficient than BNC. The results showed that BMS could activate the vulcanization process, suppress the Payne effect, and increase the modulus and hardness. Moreover, a fine BMS dispersion and strong interfacial interaction were achieved in SBR/BMS/CB composites. The observed reinforcement effects were evaluated based on the results of G′, tanδ and scanning electron microscopy (SEM) analyses of SBR/BMS/CB in comparison with SBR/BNC/CB composites.
