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.
rubber antioxidant dtpd (3100) vennok,vestox dtpd is para phenylene diamine anti-aging agent, chloroprene adhesive antiozonidate. it is high efficient anti-aging agent in tyre industry and can also be applied to various rubber products. vestox dtpd is with good long-term performance especially when it is combined with antioxidant 6ppd (4020) or ippd (4010na), which is the best.
best selling rubber antioxidants tmq particles
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 [12].
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.
- 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.
- 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].
- Are rubber antioxidants toxic?
- (2) The toxic effects of rubber antioxidants and their TPs may be evaluated via computational toxicology combined with traditional toxicological methods, including studies of short-term and sub-lethal exposure effects, the potential for mortality, mechanism of effect, and interaction with environmental variables.
