REINFORCING FILLER FOR RUBBER. |
摘要 |
<p>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.</p> |
