synthesis and properties of a novel reactive and low-migration,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 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.
(pdf) comparison of antiaging and antioxidant activities of,antioxidant activities were performed by measurement of 2,2-diphenyl 1-pichylhydazyl (dpph) free radical scavenger, ferric reducing antioxidant power (frap), and 2,2'-azino-bis (3.
best selling rubber antioxidants tmq particles
china is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. the production of rubber antioxidants in china ranged from 365,000 to 378,000 tons during 2016–2020, showing a
antioxidant modified graphene oxide for robust and highly aging,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.

environmental chemical rubber antioxidants,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 [ 17 ].
- Can antioxidants prevent rubber aging?
- 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).
- 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 .
- What is oxidative aging of rubber?
- Thermal oxidative aging is the most frequent type of rubber degradation. To delay or prevent this process, antioxidants can be added to rubber compounds during mixing. (9) Antiaging agents react primarily with the free radicals or hydrogen peroxide generated during rubber aging.
- 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 .
