  • 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 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 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:
  • Which antioxidants are used in rubber vulcanization?
  • The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
