synthesis and properties of a novel reactive and low,the pa 6-g-hp sample exhibited a lower thermo-oxidative degradation rate constant than the pa 6/irganox 245 sample. moreover, the antioxidants in the pa 6/irganox 245 sample migrated faster, resulting in higher equilibrium migration concentrations.
this paper discusses the application of rubber antioxidant tmq (rd) in various rubber products such as all-steel and semi-steel radial tires, hoses and belts, and its advantages, demonstrating its excellent anti-aging ability.
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 organisms and even lead to environmental events, which led to great public concern about environmental
(pdf) rubber antioxidants and their transformation products,5. environmental occurrence and potential impact of antioxidants and tps the concentrations of various antioxidants and their tps in water, dust, and air are summarized in table 1. the rubber antioxidant might be released into the environment during the life cycle of tires, and especially the wear of automobile tires [60,61].

recent progress in the rubber antioxidants Rubber Auxiliary Agent,in the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (mbz:445=2:1) is superior to that of other samples (fig. 2 c), demonstrating the synergistic antioxidative effects between mbz and 445 for epdm.

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

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.
rubber antioxidants and chemical 6ppd,antioxidants are added to natural rubber (nr) and synthetic rubber (sr) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [4,5].
- 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.
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- 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.
