The silica dispersibility is related to the processability, mechanical properties, and abrasion resistance of tires tread rubber. To improve the silica dispersibility in the silica-SBR compound, we used wet masterbatch (WMB) process which is a method of mixing rubber in water phase. However, WMB process has difficulties in improving the mechanical properties of the rubber compound due to low silica dispersibility caused by the silica aggregation when the silica content is higher than 100 phr. Five types of silica dispersants applicable to the WMB process were applied to silica/SBR compound. The vulcanization properties, mechanical properties, and abrasion resistance of silica/SBR compounds were compared using a Moving Die Rheometer, Universal Testing Machine, and DIN wear tester, respectively.
