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.
so this kind of product can only be used in dark or black rubber products. the main products are: antiaging agent d (d), antiaging agent a (a), antiaging agent dnp, antiaging agent 4010na/ippd, antiaging agent 4020/6ppd, antiaging agent tmq/rd, antiaging

photo-induced ros production-based antioxidant/oxidant balance (aop)1 assay, live cell antioxidant assay. (1) prior to photoinduction, there is massive removal of to from cell by efflux transport.
recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
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.

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.
production and use of typical rubber antioxidants
amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
insight into the anti-aging mechanisms of natural phenolic antioxidants,in this study, we chose natural rubber (nr) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting nr composites. thymol, α-tocopherol, and lipid-soluble epigallocatechin gallate (lsegcg) were chosen from 18 natural phenolic antioxidants as potential alternative candidates.
- 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.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- 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 .
