introduction of rubber antiaging agent and its types and functions
there are anti-aging agent ndbc, anti-aging agent ndibc, anti-aging agent ndmc. all green powder. with good ozone resistance and thermal oxidation resistance, expensive (due to nickel on the earth less storage, but a wide range of uses), but also a certain toxicity, deep color, easy to spray frost, not suitable for light color rubber products, in the rubber industry consumption is very few.
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.

as a kind of ursol rubber antioxidant, 6ppd has better compatibility with rubbers, seldom blooming, low volatility, low toxicity, with excellent antioxidant, anti-ozone, anti-flex cracks , anti insolation cracks, strong inhibition on copper or manganese and other toxic
environmental chemical rubber antioxidants,rubber is a group of high-molecular-weight polymer materials with a property of elasticity at 20–27 c [], and rubber is one of such typical commercial products. rubber products are mainly used in industrial and agricultural production, transportation, and national defense construction, and antioxidants are a group of the most important chemicals with widespread use in rubber products.
- 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].
- 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 many rubber antioxidants are produced in China?
- China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend .
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
