PREPARATION OF SILICA REINFORCED RUBBER COMPOSITION, RUBBER COMPOSITION AND TIRE WITH COMPONENT
The invention relates to preparation of a precipitated silica reinforced rubber composition, a resulting rubber composition and tire with component comprised of such rubber composition. The invention relates to blending a pre-formed composite of pre-hydrophobated precipitated silica and fatty acid with a rubber composition and subsequently reacting zinc oxide therewith in situ within the rubber composition to form a zinc salt of such fatty acid of said composite. The invention further relates to promoting said reaction of said zinc oxide and said fatty acid of said composite in situ within the rubber composition in the presence of an oligomer of 1,2-dihydro-2,2,4 trimethylquinoline. The invention additionally relates to a rubber composition thereof and tires with component of such rubber compositions such as a tire tread.
