What's In a Tire U.S. Tire Manufacturers Association
Bead Tire bead bundles (usually strands of wire) secure the tire to the wheel.; Bead Filler A rubber compound placed above the bead bundle that may be used between the body plies which wrap around the bead to tune ride and handling characteristics.; Belts Typically, two belts with steel cords laid at opposing angles. Belts provide stability to the tread area of the tire, which
1. Introduction. Of all synthetic rubbers, styrene-butadiene rubber (SBR) possesses the largest share in the market and has been widely used in many industrial products (e.g., tires, hoses, and tapes) because of its outstanding comprehensive properties [1,2].However, SBR products are readily subjected to thermo-oxidative aging during the
- 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 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 .
- 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.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
- 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.
- 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) .
