Application of Phenolic Resin and Carbon Black in Apexes of Tires
The application of phenolic resin and carbon black in the apexes of the tires was studied,and the properties of the compound and the performance of the finished tires were compared.The results showed that compared with the compound with only the carbon black reinforcement system,the compound with phenolic resin reinforcement system had lower Mooney viscosity,longer scorch time,slower vulcanization rate,smaller tensile stress at a given elongation and tensile strength,larger elongation at break,greater tensile set at break and rebound value,smaller tanδ at 60 ℃ and lower heat build-up.The apex had better stiffness,and the bead durability of the finished tire was better.
