The main inorganic component of rice husk is silica. Washing the rice husk, followed by combustion and chemical treatment, produced high-surface area amorphous extracted nanosilica (NS) and modified extracted nanosilica (mNS). It was established to reinforce a blend of ethylene-propylene-diene monomer (EPDM) and acrylonitrile-butadiene rubber (NBR) using different amounts of mNS, specifically 2, 4, 6, 8, and 10 phr. The cure properties, mechanical, physical, and swelling resistance examinations of the sulphur-cured nanocomposites were studied. The results showed that while the torques were prolonged with increasing mNS concentration, the optimum cure time (t90) and scorch time (ts2) decreased. The homogeneous distribution of nanosilica particles throughout the rubber matrices was confirmed by the FESEM micrographs. The outcomes guaranteed a discernible improvement in the nanocomposites' examined qualities.

“…For a long time, the application of nanofillers in rubber composites has became an effective way to improve the mechanical properties of rubber composites. A series of nanofillers have been used to reinforce rubber composites successfully, such as natural fibers [67], carbon nanotube (CNT) [68][69][70], nano clay [71][72][73], nano silica [74][75][76], nano titania [77][78][79], nano calcium carbonate [80][81][82].…”

At present, high-damping rubber materials, widely used in the field of engineering seismic isolation, generally have the problems such as narrow effective damping temperature range, low damping loss factor and strong temperature dependence, which lead to prominent dependence of temperature and load conditions of the isolation performance of high-damping rubber isolation bearings. Research and development of high-performance high-damping rubber materials with broad effective damping temperature range, high damping loss factor and weak temperature dependence are very urgent and necessary to ensure the safety of the seismic isolation of engineering structures. This paper mainly reviews the recent progress in the research and development of high-damping rubber materials using nitrile butadiene rubber (NBR), epoxidized natural rubber (ENR), ethylene propylene diene rubber (EPDM), butyl rubber (IIR), chlorinated butyl rubber (CIIR), and bromine butyl rubber (BIIR). This is followed by a review of vulcanization and filler reinforcement systems for the improvement of damping and mechanical properties of high-damping rubber materials. Finally, it further reviews the constitutive models describing the hyperelasticity and viscoelasticity of rubber materials. In view of this focus, four key issues are highlighted for the development of high-performance high-damping rubber materials used for high-damping rubber isolation bearings.

“…8, show the graph for the crosslinking density of hybrid NR/SBR composites with and without SCA. Increases in silica concentration result in a decrease in ller-rubber interaction (increases in silicasilica interaction), affecting the crosslinked density value [48][49][50][51]. The tensile strength, tensile modulus, elongation at break, and hardness of hybrid llers lled NR/SBR blends with Si69 are higher than those of NR/SBR blends without Si69 at similar blend ratios.…”

In the current research, investigation of natural rubber (NR)/styrene butadiene rubber (SBR) reinforced with carbon black (CB)/silica (Si) and with and without silane coupling agent (Si69) was analyzed. The total hybrid filler (CB/Si) concentration in the composite was fixed at 50 phr. Cure characteristics, mechanical properties and surface morphology were examined. The addition of a silane coupling agent improves the mechanical properties of NR/SBR rubber composites reinforced with CB/Si hybrid fillers. Compared with NR/SBR composites with Si69, addition of 0/50 CB/Si resulted in 53% decrease of tensile strength and 81% increase of elongation at break, superior to that of NR/SBR composites without Si69. When Si69 was used as a binding agent, the scanning electron micrograph (SEM) of the tensile fractured surface clearly shows the better dispersion of hybrid fillers in the NR/SBR matrix.
