  • Does 4010na/cb/Nr composite increase thermo-oxidative aging resistance?
  • The results shall indicate that, in comparison with 4010NA/CB/NR composite, there existed synergistic effect of antioxidant 4010NA and silica in 4010NA/SiO2 /NR composite on greatly enhancing thermo-oxidative aging resistance of NR material.
  • How does a rubber matrix affect antioxidative performance?
  • Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
  • Can rubber antioxidants contain rare-earth ions?
  • The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
  • Does antioxidant 4010na and silica enhance thermo-oxidative aging assistance?
  • In this work, the synergistic effects of antioxidant 4010NA and silica on enhancing thermo-oxidative aging assistance for NR were investigated by experiments and molecular simulations, and the mainly conclusions were generalized as follows:
