  • What are the different types of antioxidants in rubber?
  • Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
  • Which rubber antioxidants are used in China?
  • Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
  • Does nanosilica-supported antioxidation work on styrene-butadiene rubber?
  • A facile and green preparation of nanosilica-supported antioxidant and its reinforcement and antioxidation effect on styrene-butadiene rubber. Int. J. Polym. Anal. Charact. 2016, 21, 185–197. Wu, Y.P.; Zhang, Z.Z.; Wei, L.Q.; Yang, S.Z.
  • What are amine antioxidants in rubber?
  • Amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. Typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p -phenylenediamine, and aldehyde-amine condensation product antioxidants .
  • What is the global consumption of rubber antioxidants?
  • 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. This is about twice higher than that of phosphorus flame retardants, a group of emerging pollutants which received great attention in the past decades .
  • Does antioxidant 2246 protect rubber from aging?
  • Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
