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
various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
accelerators and antioxidants in the rubber industry
however, the knowledge gradually reached other rubber chemists and started them on a search for other and better accelerators. the first u. s. patents on accelerators were issued in 1915 to hofrnann and gottlob, and on this basis the claim was made (and accepted for a time) that
a brief introduction of the commonly used antioxidant,a wide range of rubber antioxidant , function each different. according to its main function can be divided into oxygen resistance aging agent, antiozonant, harmful metal ions inhibitors, resist fatigue agent, uv absorber, resistance to cracking agent.

- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . 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.
- 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.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- 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.
