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.

cn209222066u a kind of rubber antioxidant dtpd prilling
rubber antioxidant dtpd is p phenylenediamine type antioxidant, which is the efficient anti-aging agent of tire industry, is had anti- ozone function, it is anti-deflect crack resistance can be similar to antioxidant 4010na and 4020, to be got well more than antioxidant a, d, but by in p-phenylenediamine there is synergistic effect, antioxidant 4020 or 4010na to provide necessary short-term.
rubber antioxidant dtpd (3100) supplier,its performance of anti-ozone, anti-scratch and anti-cracking is far better than antioxidant a and d. dtpd has good long-term performance especially used with the antioxidant 4020 or 4010na 1:1. its greatly increased solubility in rubber and the much lower blooming allow a greater using amount. it has little influence on vulcanization and scorch.
rubber antioxidants and their transformation products
2. production and use of typical 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.
unleashing the power of dtpd: the ultimate antioxidant agent,antioxidant agent dtpd, short for diphenyl-p-phenylenediamine, is a highly effective antioxidant agent that plays a vital role in preserving the integrity and longevity of rubber products. in this descriptive piece, we will explore the features and benefits of dtpd, delving into its role in protecting rubber compounds from oxidative degradation.
cn106311284a solid acid catalyst, and application thereof
the invention relates to a solid acid catalyst, and an application thereof in the synthesis of a rubber antioxidant dtpd. the solid acid catalyst so4/tio2-zno-fe2o3-zro2-al2o3 is prepared through a reaction of 7-39 mol% of titanate, 25-40 mol% of water-soluble zinc salt, 7-15 mol% of water-soluble iron salt, 2-18 mol% of water-soluble aluminum salt, 7-23 mol% of water-soluble zirconium.
screening p-phenylenediamine antioxidants, their,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.

among them, the construction area is 9,990 m2, and there are more than 60 employees. it is mainly engaged in the research and development and production of rubber additives and new fine chemical products. the main products are rubber antioxidant dtpd (3100). "technology-based, quality first" is an important feature of the company.
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.
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
- Do recycled tire rubber products contain PPDS and TPS?
- 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 for seven PPD antioxidants, five PPD-quinones (PPDQs), and five other 6PPD TPs using liquid chromatography-tandem mass spectrometry.
- 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.
- 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].
