Synthesis of migration-resistant antioxidant and its application in natural rubber composites
Year: 2025
Type: article
Abstract: In this article, a novel migration-resistant antioxidant (CGE-g-PPDA) was synthesized using cardanol glycidyl ether (CGE) and p -aminodiphenylamine (PPDA) and characterized by infrared spectroscopy, indicating that the antioxidant has been successfully synthesized. CGE-g-PPDA and other different types of antioxidants were added to natural rubber (NR) to make anti-aging NR composites, which were tested and characterized by processing properties, aging resistance, thermal stability, cross-linking density retention properties, and migration resistance. Comparative results showed that CGE-g-PPDA could reduce the Mooney viscosity of NR, improve its processing performance, prolong the oxidation induction time of materials, give long-term protection to the rubber, and improve the cross-linking retention rate of materials. In addition, the migration resistance and solvent extraction resistance of antioxidant CGE-g-PPDA were significantly better than that of antioxidant 4020, with higher stability. CGE-g-PPDA, as a new type of migration-resistant antioxidant, has a potential application value.
