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) shows
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 chemical 6ppd
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
recent progress in the rubber antioxidants Rubber Auxiliary Agent,in this review, we systematically review the recent progress of antioxidants for rubber. 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.
synthesis and properties of a novel reactive and low
through a two-step synthesis process, lu 28 developed a reactive antioxidant, napm, added it to natural rubber, and discovered that its aging resistance was superior to those of 4010na and 4020. zhao et al. 16 grafted the antioxidant intermediate rt onto the surface of lignin and created a hybrid modified lignin-based filled antioxidant named
south korea: rubber antioxidant domestic demand 2022 statista,in 2022, domestic demand for rubber antioxidant in south korea reached over 16,000 metric tons. rubber antioxidant is used to prolong the lifecycle of rubber products by delaying their...
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...
rubber antioxidants and their transformation products,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).
- 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.
- 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.
- 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.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
