environmental chemical rubber antioxidants,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 the initiation stage of rubber aging.

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.
- 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.
- Does 6PPD ozonation pose environmental risks?
- 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
- 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].
