  • Reinforcing filler for rubber
    Patent number: 9006308
    Abstract: The present invention describes a reinforcing filler for rubber comprising the synergistic combination of precipitated silica with a pore structure defined by a maximum between 25 nm and 35 nm, a total pore volume between 1.3 cm3/g and 1.6 cm3/g, and a compression factor between 1.3 10?2 and 2.3 10?2 MPa?1, and at least one crystalline alkaline silicate corresponding to the general formula of the crystalline alkaline silicates, said crystalline alkaline silicate being swelled and/or layered in the presence of an organic cationic compound in the form of ammonium salt of the +NR4 type according to the formula [CnH2n+1N(CH3)3]+. The rubber formulation obtained by this reinforcing filler composition does present a great reduction of energy dissipated in the tread without compromising the abrasion resistance and elastic modulus properties.
