Accelerators and Antioxidants for rubber compounds
Antioxidants: protect your rubber compounds. Vulcanized rubber goods have the need, more or less marked, to be protected from the effect of external factors that can accelerate aging. These factors are of various kinds: oxidative agents (eg oxygen), agents that speed up oxidative processes (such as heavy metals), ozone, UV rays, heat
Jan 01, 2014· Natural rubber (or NR) comprises about 30% by weight of a tyre in the example shown in Fig. 12.4, which corresponds to slightly less than 60% of the polymer component (or total natural and synthetic rubbers) of a tyre. This number used to be lower, as more SR used to be used for tyres in relation to NR.

- 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.
- Are rubber antioxidants harmful?
- As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB (2-mercaptobenzimidazole), which is widely used in the manufacture of light-colored rubber products, is harmful to aquatic organisms and has a continuous effect.
- How does rubber antioxidant work?
- To prolong the service life of rubber composites by retarding their aging processes, rubber antioxidant initially relies on the use of a coating, such as paraffin, and coal tar, to physically isolate oxygen, but this protective layer would quickly lose the utility due to wear.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl3 ·6H 2 O) via coordination reaction.
