Effect of Insoluble Sulfur on Dynamic Adhesion Performance between Tire Belt Compound and Copper Plated Steel Cord
The effect of insoluble sulfur on the dynamic adhesion performance of tire belt compound with copper plated steel cord(referred to the copper plated steel)was studied.The results showed that as the amount of insoluble sulfur increased,the Mooney scorch time t5 of the compound gradually decreased,while t90-t10 gradually prolonged,Mooney viscosity,FL and Fmax gradually increased.The Shore A-type hardness of the vulcanizate increased,the modulus increased,and the tensile strength and elongation at break gradually decreased.After static and dynamic fatigue,the adhesive extraction force between the compound and the copper plated steel showed a trend of first increasing and then decreasing,the exposed area of the copper plated steel at the extraction interface first decreased and then increased,and the adhesive volume first increased and then decreased.
