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
recent progress in the rubber antioxidants Rubber Auxiliary Agent
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.
Factory Hot Sale Rubber antioxidant In Stock,in this study, we chose natural rubber (nr) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting nr composites. thymol, a-tocopherol, and lipid-soluble epigallocatechin gallate (lsegcg) were chosen from 18 natural phenolic antioxidants as potential alternative
an alternative antioxidant for sulfur-vulcanized natural
it has been concluded that henna could be used as an alternative antioxidant for sulfur vulcanization of natural rubber matrix, compensating little deteriorations in vulcanizate properties. short- and long-term performances of henna were also found to be related to vulcanization system.
antioxidant modified graphene oxide for robust and highly,in this work, rubber antioxidant poly (1,2-dihydro-2,2,4-trimethylquinoline) (rd) was introduced as organic surface modifier of graphene oxide (go) for the preparation of robust and highly anti-aging rubber composites. it was found that rd was chemically grafted on go surface by c–n bond.

rubber antioxidants and their transformation products,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.
an alternative antioxidant for sulfur-vulcanized natural
in this study, henna (henna leaves powder) has been evaluated as a natural alternative antioxidant in nr-based rubber compounds for ev and cv systems. antiaging performance of henna and tmq, which is a common synthetic antioxidant for rubber, was compared regarding the structural similarity of tmq and lawsone.
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
- 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.
- 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].
