- Is MBZ 445 a good antioxidant for EPDM?
- 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.
- 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.
- 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.
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
