rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.
synthesis and properties of a novel reactive and low
the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p-aminodiphenylamine (ppda). the product was characterized by fourier-transform.
rubber antioxidants and their transformation products,n-(1,3-dimethylbutyl)-n0-phenyl-p-phenylenediamine (6ppd or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (twps.
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
- 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.
- 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 .
- 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) .
