Data on the evolution of curing characteristics and properties during the room-temperature annealing process in...

The present article contains the data of tensile stress-strain curves, crosslinking characteristics curves, filler dispersion images and dynamic mechanical properties of SSBR/BR blends and SSBR/BR/SiO₂ composites during room-temperature annealing. The data in this article aims to accurately describe the evolution of the network structures and physical mechanical properties of rubber composites during annealing process. Tensile stress-strain curves of un-vulcanized rubber gums and compounds were obtained by an electrical tensile tester with a speed of 100 mm/min. The crosslinking characteristics of the un-vulcanized rubber blends or composites after different annealing time were measured by a rotor-free vulcameter at 150 °C. The macroscopic filler dispersion of the filled vulcanizates was analyzed on a smooth cross-section of cut rubber. The dynamic mechanical properties of vulcanized SSBR/BR blends and SSBR/BR/SiO₂ composites were investigated by a dynamic mechanical thermal analyser with different temperature ranges and strains. These findings may serve as references for the scientific processing of green tire materials in automotive industry, and this article is related to our research article entitled "Effect of room-temperature annealing on structures and properties of SSBR/BR blends and SSBR/BR/SiO₂ composites" (Xinping Zhang et al., 2019).
