Abstract:
      The mechanism and influencing factors of thermal-oxidative aging of rubber materials were analyzed，and the research status of protective technologies of rubber materials was reviewed.The differential expressions of the free radical chain oxidation reactions in different rubber materials were as follows：natural rubber materials were primarily characterized by competitive reactions of crosslinking and chain breaking of rubber molecules，styrene-butadiene rubber was more prone to secondary crosslinking due to allyl activities of rubber molecules，ethylene-propylene-diene monomer rubber exhibited early degradation characteristics dominated by broken chains due to the saturation of the rubber molecule main chain.Rubber molecular structures and environmental conditions were dual influencing factors of the thermo-oxidative aging of rubber materials，specifically including the chemical bond energy of the rubber molecule main chain and side group characteristics，and temperature，oxygen and ultraviolet actions.Traditional antioxidants effectively delayed the thermo-oxidative aging process of rubber materials through radical quenching and hydroperoxide decomposition mechanisms.While filler modification technologies significantly improved the thermal stability of rubber matrix through multiple mechanisms such as physical barrier，crosslinking network reinforcement and catalytic inhibition.Novel protective technologies include the synergistic mechanism of nano-protective materials and bio-based antioxidants.In future，the research on the thermo-oxidative aging of rubber materials should focus on the combination of multi-scale simulation and experimental verification to develop intelligent material systems that combine high protection efficiency with environmental friendliness.
