Abstract
The present invention discloses a method for preparing high-performance tread rubber through a filler silylation reaction catalyzed in situ by an ionic liquid. The method is as follow: adding a gum rubber, a filler, a silane and an ionic liquid successively into an open mill or an internal mixer for mixing to obtain a rubber compound; high-temperature remilling the rubber compound; adding a vulcanizing package and an anti-aging agent into the remilled rubber compound at room temperature; and vulcanizing the rubber compound to obtain a vulcanized rubber.
