“…31,32 Generally, the value of Tan δ at 0 C indicates the wet grip of the rubber material, and the larger the Tan δ value is, the better the wet-slip resistance. 33 As seen from the figure, among the rubber composites with the same silica content of 40 phr, after Si69 and NRL treatment, the Tan δ value of N/N-SiS40 was the highest at 0 C, and among the rubber composites with different silica contents treated by Si69 and NRL, the Tan δ value of N/N-SiS60 was the highest at 0 C, showing the best wet slip. With the increase of silica content, the wet-slip resistance of composites enhances.…”

“…The Tan δ value at 60 C represents the rolling resistance of the rubber material; the smaller the Tan δ value is, the lower the rolling resistance is. 33 The Tan δ value of N/N-SiS40 was the lowest at 60 C, demonstrating a lower rolling resistance. However, as the content of silica increased, the rolling resistance of the composites was worsened.…”

Natural rubber latex filled with silica can be used to prepare low-cost green tires with low rolling resistance. However, low mixing efficiency and reduction of properties have become the major difficulty in the industry, because there are many polar groups on the surface of silica, and it is difficult to produce a strong interaction with a nonpolar rubber. In this paper, natural rubber latex masterbatch with silica was prepared, and easily mixed with natural rubber (NR) to obtain NR/silica composites. The silica after NRL treated in the rubber matrix characterized with well dispersion, good compatibility with rubber, and composites had weaker Payne effect and higher wet-skid resistance. Meanwhile, the 100% and 300% tensile modulus increased by 8.5% and 14.47%, respectively, notably decreasing heat build-up by 41.88%, compared to the composite prepared by dry mixing technology. Overall, both the dispersion and interfacial adhesion of silica in the rubber matrix have a significant synergistic effect on the properties of rubber composites. The strategy of preparing NR/silica composites provides new research avenues for the preparation of green tires and other rubber industries in the future.

“…In general, the Tan δ at 0°C is used to measure the wet‐slip resistance of the rubber materials, that is, the larger the Tan δ , the better the wet‐slip resistance. The Tan δ at 60°C is used to represent the rolling resistance of the rubber materials, that is, the smaller the Tan δ , the lower the rolling resistance 30 . Silica50/AP1 shows better wet‐slip resistance and Silica40/AP2 shows lower rolling resistance than others.…”

The composites with excellent mechanical, low rolling resistance, and low heat build‐up are the potential materials for preparing green tires. In this study, we prepared silica‐natural rubber latex (silica‐NRL) masterbatch, which improved the processing and dispersion properties of silica in the natural rubber, proved by the rheological properties of composites. Furthermore, the idea of partial replacement of silica with low content modified aramid pulp (AP) for preparing hybrid enhanced natural rubber with high mechanical properties and low heat build‐up was put forward and evaluated the feasibility of this strategy. We find that replacing 5 phr silica with 1 phr AP, the performances of the rubber composites were all superior to the composites with only filled 50 phr silica, and replacing 10 phr silica with 2 phr AP, the mechanical and fatigue property was improved remarkably and dynamic heat generation was reduced the most at same time. The strategy of preparing silica‐NRL masterbatch and partial replacement of silica with AP provides a novel reference for the preparation of low heat build‐up green tire.

A detailed analysis of the rubber composites is necessary for the designing and fabrication of advanced rubber products. In this study, composite materials are synthesized by adding different nanofillers of carbon black nanoparticles into epoxidized natural rubber (ENR). The specific characteristics of carbon black (CB) affect the crosslinking density between CB and polymeric chains in ENR. The effects of particle size, structure, thermal conductivity, and functionality of CB on rheology and mechanical properties of filled reinforced ENR are examined. The composite materials are thoroughly characterized for their abrasion, rheology, tensile, hardness, elongation, resilience, and compression behavior. The results revealed that various properties of composite materials depend on the characteristics of the reinforcing CB fillers. It was found that lower particle size and ordered structure provide good tensile strength, tear strength, abrasion, and aging resistance. In contrast, larger particle size and a lower ordered structure provide high flow rate, low hardness, excellent re-bounce, and good compression set characteristics.
