recent progress in the rubber antioxidants Rubber Auxiliary Agent,currently, many commonly used rubber antioxidants are low molecular weight derivatives of aromatic amines and phenols, and they are plagued with volatility, migration, and extractability issues.
the amine and phenolic antioxidants are the most widely used rubber antioxidants (fig. 1 b and c). generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
rubber antioxidants and their transformation products
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.
antioxidant modified graphene oxide for robust and highly,in this work, rubber antioxidant poly (1,2-dihydro-2,2,4-trimethylquinoline) (rd) was introduced as organic surface modifier of graphene oxide (go) for the preparation of robust and highly anti-aging rubber composites. it was found that rd was chemically grafted on go surface by c–n bond.
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
rubber antioxidants and chemical 6ppd,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.
rubber antioxidants and their transformation products
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 l ….

- 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 .
- 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.
- Are rubber antioxidants harmful to human health?
- As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB Antioxidants are indispensable additives in the rubber industry as they enhance the reliability and service life of the rubber product by protecting it from degradation.
- 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 .
