recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
the aging properties and phase morphology of silica filled
large amounts of antioxidants are used in unsaturated rubber composites, such as butadiene rubber (br), which would inevitably cause surface discoloration. in this study, silicone rubber (vmq) was blended with br for improving its anti-aging properties. it was found that vmq/br exhibits better thermal oxidative
synergistic effects of antioxidant and silica on enhancing,however, in aging experiments, the anti-oxidative efficacies of 4010na in 4010na/nr or 4010na/cb/nr composite are inferior to that in 4010na/sio 2 /nr composite (based on the difference of carbonyl increase rate r with and without 4010na in table 3). in our opinion, this phenomenon is associated with the physical loss (or migration) of antioxidant.
- 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.
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- 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) .
- 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.
