  • 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 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 reduce FFV and FCV of NR?
  • (1) By means of QM simulation, the protective mechanism of antioxidant 4010NA for NR was elucidated quantitatively from the point of free energy of dissociation and energy barrier of reaction. (2) The addition of silica was capable of reducing FFV and FCV of NR, thereby improving O 2 barrier ability of NR.
  • Does 4010na have a synergistic stabilization effect?
  • Then, according to the experimental and computational results, the synergistic stabilization effect between 4010NA and SiO 2 for NR were analyzed from the perspective of oxygen (O 2) barrier ability, the protective mechanism and migration capacity of 4010NA, as well as cross-linking density.
