RUBBER COMPOSITION FOR A TIRE TREAD |
摘要 |
<p>The invention relates to a rubber composition that can be used as a tire tread having improved adhesion on melting ice, comprising at least one diene elastomer such as natural rubber and/or a polybutadiene, more than 30 pce of a liquid plasticizer, between 50 and 150 pce of a reinforcing filler such as silica or carbon black, and between 2 and 40 pce of microparticles of a water-soluble sulfate of an alkali or alkali earth metal such as a magnesium sulfate, wherein said composition is characterized in that the volumetric microparticle size distribution, measured by laser grading as per ISO Standard 13320-1, satisfies the following relations: 50 µm 50 Span 50 is the diameter of the median particle corresponding to 50% of the cumulative distribution of particles; Span = (D90 - D10) / D50; wherein D10 and D90 are the diameters of the particle corresponding to 10% and to 90%, respectively, of the cumulative particle distribution. The invention also relates to tire treads incorporating such a composition, as well as to said tires themselves.</p> |
