environmental chemical rubber antioxidants
2.1. amine antioxidants 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 [].
transformation products of tire rubber antioxidant 6ppd in,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.
screening p-phenylenediamine antioxidants, their transformation
recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized. here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers.

tmq antioxidant for rubber industry: enhancing performance
in the realm of rubber manufacturing, the utilization of effective rubber additives is crucial to ensure superior product quality and longevity. one such essential rubber additive is the antioxidant tmq, also known as rd. in this article, we will delve into what tmq is, its role in rubber product production, and the advantages it holds over other similar products in the market. tmq antioxidant.
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.
- 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.
- Do rubber tires need antioxidants?
- Antioxidants are indispensable functional additives used in rubber tires to delay aging and extend their service life (Kirschweng et al. 2017 ). Six common types of tire antioxidants include amines, polyphenols, vitamin E, sulfurous, phosphite, and other compounds of essential vitamins (Chen et al. 2008 ).
- Are tire antioxidants toxic to aquatic organisms?
- Various antioxidant derivatives are produced during the process of free radical scavenging by tire antioxidants. The toxic effects of some of these derivatives on aquatic organisms are reviewed in the literature. Tian et al. found that 6PPD-quinone, a derivative of tire antioxidant 6PPD, can cause acute death of silver salmon (Tian et al. 2021 ).
- 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 .
