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.

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.

- Are rubber antioxidants effective against aging and antimigration?
- The antiaging and antimigration properties of the rubber antioxidants were enhanced without damaging the mechanical properties of the rubber matrix. The short-term and long-term antiaging and antimigration properties of this antioxidant are superior to those of commercially available antioxidants. CC-BY-NC-ND 4.0 . 1. Introduction
- What is the aging time of rubber?
- The aging time was 3 days. The relative contents of the rubber surface elements were measured using XPS. The table shows the relative contents of the surface nitrogen elements in the three groups of samples before and after aging.
- 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 hydroxytoluene stop the autocatalytic aging reaction of rubber?
- For instance, as shown in Fig. 1 b, butylated hydroxytoluene (BHT) could donate a hydrogen atom and convert peroxy radical to hydroperoxide, and therefore it could stop the autocatalytic aging reaction of rubber by blocking the propagation of peroxy radicals (Fig. 1 b), each BHT consumes two peroxy radicals. 3.
