  • 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.
  • 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.
  • Are rubber antioxidants a rational design?
  • The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
  • 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.
