Application of Diacylhydrazine Material CSC920 in Tread Base Compound of Truck and Bus Radial Tire
The application of diacylhydrazine material CSC920(abbreviated as CSC920)in the tread base compound of truck and bus radial tires was studied.The results showed that CSC920 had a good modification effect on natural rubber,which could significantly accelerate the vulcanization reaction rate of the compound and increase the Mooney viscosity of the compound.After adding CSC920,the modulus at a given elongation,tensile strength,and elasticity of the base compound were improved,while the rolling resistance and heat build-up were significantly reduced.During the mixing process,the addition of CSC920 before zinc oxide resulted in better physical properties of the base compound and a significant reduction in compression heat build-up,the addition of CSC920 after zinc oxide could have an anti-reversion effect,improving the physical properties of the base compound,but the effect of reducing heat build-up was not significant.
