rubber antioxidants and chemical 6ppd
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).
recent progress in the rubber antioxidants Rubber Auxiliary Agent,various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
- Can hydroxytoluene stop the autocatalytic aging reaction of rubber?
- For instance, as shown in Fig. 1 b, butylated hydroxytoluene (BHT) could donate a hydrogen atom and convert peroxy radical to hydroperoxide, and therefore it could stop the autocatalytic aging reaction of rubber by blocking the propagation of peroxy radicals (Fig. 1 b), each BHT consumes two peroxy radicals. 3.
- Does a sustained release of EAB improve anti-oxidative capacity of rubber composites?
- Moreover, the retention of EAB for SBR/Loaded HNTs is about 50% higher than for SBR/HNTs and CDs after the thermo-aging testing, demonstrating the sustained release of CDs from HNTs could enhance the anti-oxidative capacity of the rubber composites.
