The production of a new class of plastics with improved properties can be achieved through polymer blends rather than using individual components. This study involved the preparation of nanocomposite ternary blends comprising natural rubber (NR), styrene-butadiene rubber (SBR), and acrylonitrile rubber (NBR), incorporating nanoclay (NC) through a melt compounding process. Subsequently, the mechanical properties of these NR/SBR/NBR ternary blends nanocomposites were examined. Throughout the study, the NR/SBR/NBR content remained constant at 30/30/40 phr, and an ultrablend 4000 at 3 phr was used as a compatibilizer, while varying the fractions of nanoclay. The study's results demonstrated a notable enhancement in the stability of scorch time and the optimum cure time of the nanocomposites through the incorporation of nanofillers. Moreover, the nanoclay content was directly proportional to the increase in tensile properties (tensile strength, stress at 100% elongation and elongation at break %), abrasion resistance, and compression set of the nanocomposites. However, the mole percent uptake exhibited a noteworthy decrease as the nanoclay content increased. Further analysis using FESEM of the tensile fracture surfaces revealed that the inclusion of nanoclay in the nanocomposites led to better adhesion of NR/SBR/NBR rubber and enhanced tensile properties. This study demonstrates the potential of utilizing nanocomposites in polymer blends to enhance the overall performance of elastomers.

“…The choice of using these systems without applying any other typical compounds generally included in the vulcanization, responds to the need for achieving a process to recycle GTR that must be as economically viable as possible. Moreover, it has been proven that, when preparing mixtures using waste rubber, there is a migration of unreacted components, including accelerators or plasticizers [ 24 , 25 ]. Therefore it is theoretically possible to carry out reclaiming and revulcanization processes using, for example, sulfur alone.…”

Reactive Sintering of Ground Tire Rubber (GTR) Modified by a Trans-Polyoctenamer Rubber and Curing Additives

The proposed method of ground tire rubber (GTR) utilization involves the application of trans-polyoctenamer rubber (TOR), a commercially available waste rubber modifier. The idea was to investigate the influence of various curing additives (sulfur, N-cyclohexyl-2-benzothiazole sulfenamide (CBS), dibenzothiazole disulfide (MBTS) and di-(2-ethyl)hexylphosphorylpolysulfide (SDT)) on curing characteristics, physico-mechanical, thermal, acoustic properties as well as the morphology of modified GTR, in order to evaluate the possibility of reclaiming GTR and the co-cross-linking between applied components. The results showed that the presence of the modifier without the addition of curing additives hinders the physico-mechanical properties of revulcanized GTR. The addition of SDT, CBS, MBTS and sulfur change the melting kinetics of TOR, indicating partial degradation and/or co-cross-linking between components. In the studied conditions, the best mechanical properties were obtained by the samples cured with sulfur. The morphology analysis, combined with the physico-mechanical results, indicated that when the surface of the GTR is more developed, obtained by the addition of TOR, the properties of the GTR improve.

“…Compounding two or more elastomers together at the gum stage is gaining decent attention by researchers. 8,13 -15 El-Sabbagh and Yehia 9 have compared the cross-link densities for NR/SBR or NR/NBR blends. They revealed that the stress at 100% (M100) or 200% (M200) elongations and Young’s modulus are increased by increasing NBR or SBR in the blend, while tensile strength (TS), strain at break, and fatigue life are decreased.…”

Polymer blends lead to producing a new class of plastics, which may have better properties than being individual. In this study, the ternary blends of natural rubber (NR)/styrene-butadiene rubber (SBR)/nitrile rubber (NBR) were prepared via melt compounding, and then the physicomechanical properties of ternary NR/SBR/NBR blends were investigated. NR content was kept constant at 30 phr, while SBR and NBR fractions were varied simultaneously. The effect of the addition of 3 phr of ultrablend 4000 as compatibilizer on the compatibility of the rubber blends was studied. The results revealed that the use of the compatibilizer has significantly resulted in the clear stability of the scorch time and the optimum cure time of the blends. Tensile strength; stress at 100%, 200%, and 300% elongations; elongation at break %; compression strength; and compression set increase with the NBR content. There was a dramatic rise in the value of swelling ratio with the decrease of NBR. Moreover, the dynamic mechanical analysis showed some shifts in glass transition temperatures for blends to higher and lower temperatures as a function of the composition, which indicates the partial miscibility between the contributing components. Scanning electron microscopy of the tear fracture surfaces indicated that incorporation of NBR in the blends resulted in better adhesion of ternary blends and improved the tensile properties of ternary blends.
