the effect of antioxidant concentration of n-isopropyl-n,study the influence of high concentrations of antioxidants n-isopropyl-n-phenyl-p-phenylenediamine (ippd) and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq) and the mixing time of the vulcanization physical properties, thermal properties, mechanical properties and structure micro on natural rubber compound has been done.
recently, li et al. used two kinds of antioxidants, i.e., 4,4’-bis(α, α-dimethylbenzyl) diphenylamine (antioxidant 445, fig. 2 a) and 2-mercaptobenzimidazole zinc (antioxidant mbz, fig. 2 b), to improve the anti-aging performance of ethylene propylene diene rubber (epdm) by making full use of each antioxidant's advantage and character [9].
rubber antioxidants and chemical 6ppd
in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.
widely used good price rubber antioxidant ippd,substituted para-phenylenediamine (ppd) antioxidants have been extensively used to retard oxidative degradation of tire rubber and were found to pervade multiple environmental compartments. however, there is a paucity of research on the environmental occurrences of their transformation products.
transformation products of tire rubber antioxidant 6ppd for sale
abstract. 6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
p-phenylenediamines and p-phenylenediamine quinone,N-(1,3-dimethyl-buty)-N'-phenyl-P-Phenylenediamines (ppds) are widely used in the rubber industry to effectively prevent oxidation of rubber by ozone, inhibit aging of rubber, and improve product application performance and service life (cataldo, 2018, cataldo, 2019, cataldo et al., 2015).
widely used chemical rubber antioxidant ippd
N-Isopropyl-N'-phenyl-p-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. like other p-phenylenediamine -based antiozonants it works by virtue of its low ionization energy, which allows it to react with ozone faster than ozone will react with rubber.

rubber antioxidants and their transformation products,in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.
data for effects of lanthanum complex on the thermo-oxidative
novel mixed antioxidants composed of antioxidant ippd and lanthanum (la) complex were added as a filler to form natural rubber (nr) composites.
improvements of lanthanum complex on the thermal-oxidative,mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prepare natural rubber (nr) samples.
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
- 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].
- What additives are used to prepare natural rubber (NR) samples?
- Mixed antioxidants composed of antioxidant IPPD and novel rare earth lanthanum complex were used as an additive to prepare natural rubber (NR) samples.
- Are rubber antioxidants toxic?
- Recent advances in the toxicity issue of rubber antioxidant With the increasing popularity of automobiles, tire wear particles, generated from tire material during use on roads, would ultimately enter the eco-system, such as soil, aquatic environment, etc .
