  • What causes oxidative aging of rubber?
  • Various external factors, including oxidative agents (such as oxygen), heavy metals, UV rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
  • Are anti-aging agents effective for rubber composites?
  • As shown in Table 2, the anti-aging agents MC-HS911, MC-BY and MC-ODA showed superior mechanical retention rates compared with MC-Blank, while the anti-aging agents RD and DAPD were ineffective for rubber composites. These conclusions are consistent with the above tests.
  • 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) .
  • Do anti-aging agents affect aging properties of composites?
  • Meanwhile, the addition of antioxidants promoted the slippage between the rubber molecular chains, which was beneficial to the processing performance of the composites. Finally, the effects of different anti-aging agents on aging properties of the composites at different time and temperatures were analyzed as well. 2. Experimental section 2.1.
