antioxidant sustained release from carbon nanotubes for,In this work, a new strategy is proposed to avoid antioxidant blooming and improve the aging resistance of styrene butadiene rubber (SBR), using carbon nanotubes (CNTs) loaded with antioxidant N-(1,3-dimethyl)butyl-N′-phenyl-p-phenylenediamine (4020) as filler.
we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants. after that, recent advances to minimize the blooming and migration of antioxidants are summarized.
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.
natural rubber composites with antioxidant‐loaded activated,in this manuscript, the authors prepared natural rubber composites by integrating antioxidant 4020 with activated calcium silicate (acs) using a simplified loading method, which improved the...

in fact, selecting effective alternatives from hundreds of natural aos for polymer materials is tentatively in investigation. 23–25 guitard et al. reported a comparative assay that followed the investigation of the antioxidant activity of phenols.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,after 168 hours of thermal oxidative aging test at 100℃, styrene‐butadiene rubber with 10 wt % surface thiol functionalized mesoporous silica nanorods loaded with 4020 (msn‐sh‐4020)...
(pdf) 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.
rubber antioxidants and chemical 6ppd,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).
synthesis and properties of a novel reactive and low
rubber composites containing antioxidants 4020 and 4010na were immersed and extracted, resulting in solutions that were noticeably darker in color than those of the rubber composites with gma-ppda antioxidants, which had also been immersed.

- Are rubber antioxidants harmful to the environment?
- 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 antioxidants and their TPs.
- What are the different types of antioxidants in rubber?
- Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
- What is the global consumption of rubber antioxidants?
- 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. This is about twice higher than that of phosphorus flame retardants, a group of emerging pollutants which received great attention in the past decades .
