“…It is believed that the key factors for the improvement in the mechanical properties was thought to be the high aspect ratio of layered silicate and the intercalation of rubber molecules into intergalleries of layered silicate which provided greater surface area for the interaction between OMMT and rubber matrix. This enables effective transfer of the applied stress to the silicate layers [22,23]. This may be explaining the improvement in TS of EPDM-CNs nanocomposites.…”

Effect of electron beam irradiation on the mechanical and physicochemical properties of both styrene butadiene rubber (SBR)/clay and ethylene propylene diene monomer (EPDM)/clay nanocomposites containing clay contents from 3 to 10 phr prepared by melt blending method has been investigated. The prepared composites were subjected to electron beam irradiation doses of up to 150 kGy to induce radiation curing, whereas the mechanical properties in terms of tensile strength (TS), tear strength (Ts), and elongation at break (Eb) were studied as a function of irradiation dose and clay content. TS and Ts increased with increasing irradiation dose up to 100 kGy, they were decreased with further increase in dose. An increase in TS and Ts for SBR and EPDM nanocomposites containing various organomodified montmorillonite (OMMT) contents (3–5 phr) was noticed, whereas a decrement behavior was observed at higher OMMT content. The elongation at break decreased continuously with both irradiation dose and OMMT content. The crosslink density for either EPDM or SBR samples increases with increasing irradiation dose up to 150 kGy and by increasing clay content up to 5 phr, whereas it decreases at higher clay content (7–10 phr). At 5 phr OMMT and 100 kGy irradiation, SBR nanocomposites showed higher TS and Ts than EPDM nanocomposites, while the crosslink density of SBR is lower. POLYM.

“…It is apparent that OMMT acted as a vulcanizing accelerator by reducing T S (scorch time), T 90 (cure for 90%) and improving the cure rate index (V C ). Such an accelerating effect has already been reported for some other rubber nanocomposites [14]. The possible formation of a Zn complex, in which both sulfur and amine participate by intercalating into the montmorillonite (MMT) layers, may facilitate the development of elemental sulfur [15].…”

Almost completely exfoliated natural rubber/butadiene rubber/organophilic montmorillonite (NR/BR/OMMT) nanocomposites were successfully prepared by mechanical blending. The optimal type of OMMT was carefully selected, using characterization by X-ray diffraction (XRD) and the mechanical properties of composites, from three NR/BR/OMMT composites with different kinds of OMMT. The almost completely exfoliated NR/BR/OMMT nanocomposites were confirmed by transmission electron microscopy (TEM) and XRD. Then a series of NR/BR/OMMT (the optimal organoclay) nanocomposites with various amounts of OMMT were prepared and characterized. The results showed the tensile strength and tear strength of nanocomposite with only 3 parts per hundreds of rubber (phr) of clay were improved by about 90.8 and 54.0% in comparison with the pure NR/BR, respectively1 and the stress relaxation behavior showed the equilibrium stress was higher than that of the pure sample. The increase of the cure rate index (VC) and reduction of the optimum time (T 90 ) indicated the efficiency of vulcanization was improved. The addition of OMMT also improved the oil resistance of the NR/BR composite1 however, the thermal stability was not changed significantly. The outstanding performance of these tire sidewall materials with OMMT reinforcement means that they are good prospects for application in the tire industry.

“…In BR as the matrix, better mechanical performance was obtained with 3 phr OC (Mt/dimethyl dihydrogenated tallow quaternary ammonium) compared with 10 phr of CB [114]. In NBR as the matrix, a comparable tensile strength was obtained with either 10 phr OC or with 40 phr CB [115].…”
