recent progress in the rubber antioxidants Rubber Auxiliary Agent,we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants. after that, recent advances to minimize the blooming and migration of antioxidants are summarized.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- 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) .
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
