Influence of acetone extract from natural rubber on the structure and interface interaction in NR/silica composites

Interfacial interaction modes construction of various functional SSBR–silica towards high filler dispersion and excellent composites performances

“…29 Additionally, the formation of covalent bonds induced by the esterication reaction between the carboxyl groups and silanols of silica during the compounding process on an open-mill at room temperature was conrmed by Jia's research. 30 As a result, dual interaction modes of hydrogen/ covalent bonds exist in silica/SSBR-g-MUA composites. [30][31][32] It is well known that the alkoxysilane groups of bis(3triethoxysilylpropyl)tetrasulde (TESPT) can react in situ with silanols of silica under shear force during the compounding process.…”

[30][31][32] It is well known that the alkoxysilane groups of bis(3triethoxysilylpropyl)tetrasulde (TESPT) can react in situ with silanols of silica under shear force during the compounding process. 6 Therefore, the alkoxysilane groups contribute to single covalent bonds with the silanols of silica in the silica/SSBR-g-MPTES composites.…”

Mechanical Properties of Natural Rubber Filled with Foundry Waste Derived Fillers

“…Rubber materials were mainly composed of rubber matrix, reinforcing fillers and other additives. The total content of reinforcing filler in rubber composites is usually greater than 50% [13,14,15]. Carbon black and silica are the most used reinforcing fillers for rubber composites.…”

“…However, carbon black is a non-renewable material that is derived from petroleum, and the preparation of silica involves harsh chemicals. The utilization of renewable materials and/or waste-derived materials possessing good reinforcing and processing properties, as well as being of low cost, is highly desired in the rubber industry [13,14,15,16]. Barrera et al reinforced natural rubber with eggshell, tomato peels, carbon fly ash and guayule bagasse, respectively.…”

A comparative study of the cure characteristics, mechanical properties and abrasion resistance of silica and carbon black filled NBR/SBR Blends

“…This can be attributed to two factors the first is the presence of filler in the rubber matrix, which decreases the mobility of the macromolecular [21]. While the other is due to the formation of some hydrogen bonding reducing strong binding of rubber blend to filler surfaces [22].…”
