  • 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.
  • Does antioxidant 4010na increase k value in Nr/CB/Nr composite?
  • Moreover, upon adding antioxidant 4010NA into NR or CB/NR composite, the K values for 4010NA/NR or 4010NA/CB/NR composite did not exhibit a significant improvement. In contrast, it is noticeable that the addition of 4010NA caused a significant increase in K value for 4010NA/SiO 2 /NR composites in comparison with SiO 2 /NR composite.
  • Does antioxidant 4010na play a better protective role in 4010na/sio 2 /nR composite?
  • Of note, antioxidant 4010NA played a better protective role in 4010NA/SiO 2 /NR composite depending on the difference in the carbonyl increase rate for the presence and absence of antioxidant 4010NA, i.e., NR and 4010NA/NR, CB/NR and 4010NA/CB/NR, SiO 2 /NR and 4010NA/SiO 2 /NR.
  • 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.
