rubber antioxidants and their transformation products mdpi,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 occurrence and potential impacts of rubber.
environmental chemical rubber antioxidants
natural antioxidants are only found in nr, such as amino acids, tocotrienol, and betaines [], whereas physical and chemical antioxidants are widely used in various synthetic rubber products. the rubber-aging process comprises three stages: initiation, reaction, and termination [ 15 , 16 ], and the physical antioxidants are usually used to address the initiation stage of rubber aging.

synthesis and properties of a novel reactive and low-migration,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 product was characterized by fourier-transform.
- 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.
- 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.
- 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) .
- 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.
