the antioxidative effect of silica-s-tp for rubber composite is superior to for the traditional antioxidants such as 4020, rd, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-tp was stem from the polyphenol on the silica surface.

efficient anti-aging technique is crucial for the practical applications of various polymers, especially for rubber composites. capture and stabilization of active free radicals produced during polymer aging is crucial to prevent the self-catalytic aging process [ 9 ].
synthesis and properties of a novel reactive and low,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 complexity of thermo-oxidative aging factors along with the lack of quantitative tools significantly hampers its applications. so, building a screening strategy to quickly and easily find an appropriate and eco-friendly ao is imperative. in this study, we chose natural rubber (nr) as a matrix and provided
rubber antioxidants and their transformation products,among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21,22].

the mechanisms of high-efficiency and the thermo-oxidative of the ao/nr systems were investigated through the combination of simulation and experimental methods, and the toxicity test was also evaluated.
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.
- 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
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- 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) .
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
