rubber antioxidants and their transformation products,natural antioxidants are only found in nr, such as amino acids, tocotrienol, and betaines , whereas physical and chemical antioxidants are widely used in various synthetic rubber products. the rubber-aging process comprises three stages: initiation, reaction, and termination [ 15 , 16 ], and the physical antioxidants are usually used to address.
- 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.
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- What is the global consumption of rubber antioxidants?
- To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives. This is about twice higher than that of phosphorus flame retardants, a group of emerging pollutants which received great attention in the past decades .
- 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) .
