synthesis and properties of a novel reactive and low,the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p-aminodiphenylamine (ppda). the
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental

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.

effectiveness of different kinds of antioxidants in resin
the effectiveness of several antioxidants belonging to different chemical classes such as p-phenylene diamine (antioxidant 4010na), secondary amine (antioxidant 445), quinoline (antioxidant rd), and phenolic (bht, 1010, 2246) on the performance of a resin-cured biir vulcanizate was investigated.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,currently, many commonly used rubber antioxidants are low molecular weight derivatives of aromatic amines and phenols, and they are plagued with volatility, migration, and extractability issues.

the majority of primary antioxidants for polymers are sterically hindered phenols. part of primary antioxidants, are aromatic amines, mainly used in carbon-black filled rubbers and some polyurethane applications. irganox ® 5057 is such an aromatic amine for polyol and rubber stabilization.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,the most widespread used antioxidants are phenolic and amine-based synthetic antioxidants and 2,2,4-trimethyl-1,2-dihydroquinoline in rubber industry.
- 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.
- 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.
- Does a sustained release of EAB improve anti-oxidative capacity of rubber composites?
- Moreover, the retention of EAB for SBR/Loaded HNTs is about 50% higher than for SBR/HNTs and CDs after the thermo-aging testing, demonstrating the sustained release of CDs from HNTs could enhance the anti-oxidative capacity of the rubber composites.
- Do rubber antioxidants in tire filtrates affect soil worms?
- This implies that rubber antioxidants in tire filtrates could disturb microorganisms in the surrounding soil, reduce the number of soil worms, and even threaten the terrestrial ecosystem by affecting soil organisms and their intestinal microbiota.
