Production of crumb rubber by emulsion polymerization has been the traditional process for production of synthetic rubber. It is still the most commonly used process, accounting for 90% of the world's production of SBR. Figure 10-14 presents a schematic diagram of the emulsion crumb rubber production process.
- 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.
- 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.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
- Are carbon dots a rubber antioxidant?
- Carbon dots as rubber antioxidants The carbon materials, such as carbon black, graphene, fullerene, etc, are well known to be able to retard the aging processes of various polymers including polyolefine, rubber, polyamide, etc., due to the active trapping of radicals .
- Can hydroxytoluene stop the autocatalytic aging reaction of rubber?
- For instance, as shown in Fig. 1b, 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.
