- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . 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.
- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- 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 are amine antioxidants in rubber?
- Amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. Typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p -phenylenediamine, and aldehyde-amine condensation product antioxidants .
- 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].
- Can antioxidants be added to rubber during mastication?
- Antioxidants are added to natural rubber (NR) and synthetic rubber (SR) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [4, 5]. In addition, they could also be coated on the NR surface to achieve a similar effect .
