“…As seen in Figure 2B, ZnO nanoparticles are arranged in one dimension forming an elongated shape, so it softens the blend and lowers the stiffness of the vulcanisate. Similar observations were described elsewhere [15][16] , suggesting that the modulus of composites is not only influenced by a filler's particle 10 size. The hardness results of the blends containing ZnO nanoparticles is increased with increasing content of ZnO nanoparticles where the blends exhibited significantly higher than conventional ZnO at the loading of 3.75 phr.…”

“…Thermogravimetric analysis (TGA) and thermal ageing have proven to be successful techniques to determine the thermal stability of polymers and polymer blends [10] . Since the thermal stability of the rubber vulcanisates concerns directly the degree of entanglement and cross-link density, the information on dynamic mechanical analysis is useful in studying blending structure and performance.…”

In the present study, recycled ethylene-propylene-diene rubber (R-EPDM) was used in an attempt to create a value added natural rubber (NR) material based on NR/R-EPDM blends. ZnO nanoparticles were also incorporated in a way to replace the conventional ZnO together with a special attention to improve the thermo-mechanical performance of the blends. Polyhedral and spherical shapes of ZnO nanoparticles were synthesised and it was found to have no impurities with a dimension ranging from 10 -40 nm. ZnO nanoparticles not only act as a curing activator but also improve the thermal stability and dynamic mechanical properties of the blends.

“…Finally, we compared the experimental results with the predicted SED function using the master curve. The SED function was derived by substituting the average temperature (17 • C) and the number of days (365, 730 days) into the aged master curve (6). The crosslink density of the aged specimen at room temperature was substituted into the crosslink-density master curve (7) and the SED function was derived and compared.…”

“…Therefore, in most product-development stages, accelerated [5,6] test methods are mainly used, which are tested with aged rubber material under severe conditions. The physical-property change parameters for the aged rubber are typically evaluated using the hardness, tensile strength, permanent set, and elongation [7][8][9].…”

Study on the Aging Behavior of Natural Rubber/Butadiene Rubber (NR/BR) Blends Using a Parallel Spring Model

et al. 2018

Natural rubber/butadiene rubber (NR/BR) blends are widely used in industrial areas for absorbing vibrations and shocks because of their excellent elastic stability. However, when an industrial-equipment surface is exposed to sunlight and oxygen over a long period of time, the rubber hardens. As a result, the tensile properties of the rubber material and the behavior of the strain-energy density function are changed, greatly reducing the performance of the rubber product. However, only a few experimental studies on the aging characteristics of NR/BR blends are available, and it is difficult to find a study that analyzes the organic relationship of the changes in the mechanical (stress-strain curves, strain-energy density, etc.) and chemical (cross-linked structure, crosslink density, etc.) properties. In this study, a swelling test was performed on an aged rubber compound, and the result was substituted into the Flory-Rehner equation to obtain the quantitative crosslink density. The results revealed a linear relationship between the strain-energy density (SED) and the crosslink density (CLD) when the cross-linked structure increase was represented by a parallel spring model. Finally, the relationship between the strain-energy density and the crosslink density was summarized as a formula, and a method for predicting the aging behavior of NR/BR blends using the crosslink density was proposed.

“…However, nitrile rubber is relatively sensitive to aging. [1][2][3] Much work has been done to study the aging behavior as well as the aging mechanism at elevated temperature, [4][5][6][7][8][9][10][11][12] , UV light [13] and Ozone. [14] .…”
