  • 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.
  • 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.
  • Which raw materials are used to prepare Nr & 4010na blends?
  • To avoid the disturbance of other additives, we only used raw materials NR, filler (CB or SiO 2 ), and antioxidant 4010NA to prepare NR, 4010NA/NR, CB/NR, 4010NA/CB/NR, SiO 2 /NR, and 4010NA/SiO 2 /NR blends. The weight loss of these blends were measured by TGA at 150 °C under nitrogen atmosphere.
  • 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.
