  • 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.
  • 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.
  • What is the antioxidative effect of silica-s-TP for rubber composite?
  • The antioxidative effect of silica-s-TP for rubber composite is superior to for the traditional antioxidants such as 4020, RD, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-TP was stem from the polyphenol on the silica surface.
