“…As the RR content increased from 0% to 20%, Ts and Ha of the composites increased. The increasing trend in Ts was similar to that obtained by De et al (2013). At an RR content of 20%, the maximum Ts and Ha of the composites were obtained, and were 33.9% and 2.3% better compared with the control, respectively.…”

“…The curing characteristics, including the minimum torque (ML), maximum torque (MH), scorch time (ts2), and t90, were measured with a no-rotor rheometer (JZ-6029, Jingzhuo Company, Yangzhou, China) according to the standard GB/T 16584 (1996). The authors used the methods of 72-h toluene swelling (De et al 2013) and 24-h water immersion according to the Chinese standard GB/T 11718 (2009) to measure the swelling and water absorption of composites at room temperature. Cut from the vulcanized specimens and dried overnight in a vacuum desiccator, circular samples with a diameter of 10-mm and square samples with a size of 50 mm × 50 mm × 2 mm were prepared.…”

“…At an RR content of 20%, the maximum Ts and Ha of the composites were obtained, and were 33.9% and 2.3% better compared with the control, respectively. It has been reported that RR has a good plasticity and could be used as a reinforcing agent (De et al 2013). However, if too much RR was added (> 20%), the vulcanization of the rubber and the processing of the composites became difficult because of the lack of curing agents (sulfur) and the increase of inorganic impurity.…”

“…8b to 8d, wetted fibers with better interfacial bonding were seen between the WFs and RC/RR matrices, which confirmed there was an optimum reinforcing effect caused by the addition of RR. When the RR content was less than 20%, smaller fragments and shorter chains in the RR acted as plasticizers (De et al 2013), which could help with the mixing process between WFs and RC/RR matrices. However, when a greater amount of RR was added (≥ 30%), the distributions of the WF became non-uniform and the fracture surface became rough.…”

This research investigated the use of reclaimed rubber (RR) from waste tires to partially replace the rubber compound (RC) when making wood fiber-rubber composites (WRCs). Ninety panels of WRC containing RR were manufactured with RR contents of 0% to 40%, mixing times of 6 min to 14 min, and vulcanizing temperatures of 150 °C to 170 °C. There were three steps, which were the fiber-rubber mixing, tabletting, and vulcanization molding processes. Four regression equations for the tensile strength, elongation at break, hardness, and rebound resilience as functions of the RR content, mixing time, and vulcanizing temperature were derived, and a nonlinear programming model was developed to obtain the optimum panel properties. It was found that when the RR content was within 20%, the wood fibers were well encapsulated and embedded in the RC/RR blends, and the processability of the WRCs were improved by adding RR. The incorporation of RR into the WRCs increased the average tensile strength and hardness by 33.9% and 2.3%, respectively, while the swelling ratio in toluene and 24-h water absorption were reduced by 13% and 42%, respectively.

“…Similar to scorch time, optimum cure time decreased with increase in GTR/RTR loading and stabilizes at higher loading [63,70,[72][73][74][75][76]. The reasons are similar to reasons for decrease in scorch time.…”

AbstractThis review addresses the progress in waste tire recycling with a particular attention to incorporation of waste tire rubber (WTR) into polymeric matrices. Methods of waste tire downsizing, importance of WTR characterization and current practice of WTR modification has been emphasized. Detailed discussion on influence of WTR size, loading, modification, compatibilization and crosslinking on the rheological, mechanical and thermal properties of rubber, thermoplastic and thermoplastic elastomer blends utilizing WTR has been reported.By far, thermoplastic elastomer blends; though still in its infancy; has shown the most promising properties balance which is capable of commercialization. Rubber/WTR blends 2 also show ease of processing and acceptable properties. Thermoplastic/WTR blends suffers in term of toughness and elongation at break. However, the waste thermoplastic/WTR is a viable solution to address polymeric waste problem. Review also highlights the lack of studies concentrating on dynamic mechanical, aging, thermal and swelling properties of WTR polymeric blends.

Two different kinds of micro‐nanoconstrained damping structure units (M‐NCDSUs) were prepared by carboxyl‐terminated butadiene acrylonitrile copolymer and epoxy‐terminated butadiene acrylonitrile copolymer liquid rubbers intercalating organic montmorillonite, respectively. The prepared M‐NCDSUs were then blended with epoxy resin to obtain damping structure integration nanocomposites. The X‐ray diffraction and transmission electron microscope measurements applied for the obtained samples confirmed the good formation of M‐NCDSUs in the epoxy network. The tensile strength decreased slightly with the addition of M‐NCDSUs, whereas the damping properties measured by dynamic mechanical analysis showed a remarkable increase. Besides, the cured epoxy resin exhibited a two‐phase morphology where the spherical rubber phase dispersed uniformly in the epoxy matrix. The nanocomposites containing M‐NCDSUs showed superior comprehensive properties compared with that without the functional units. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 39797.
