    摘要: This invention relates to a dual phase rubber composition and pneumatic tire with a rubber sidewall thereof, namely a dual phased non-black colored rubber composition composed of a first pre-formed elastomer phase comprised of butyl-type rubber and EPDM rubber containing a dispersion therein of reinforcing filler comprised of a particulate amorphous precipitated silica and a second pre-formed elastomer phase comprised of a nanocomposite of natural rubber containing a dispersion therein of exfoliated clay platelets. Said exfoliated clay platelets may be substantially oriented within the tire sidewall in a parallel direction to each and may also be substantially oriented in an annular direction about the axis of the tire. The tire sidewall rubber composition may contain at least one additional elastomer which may be included in either or both of said elastomer phases. Such tire sidewall rubber composition may contain a non-black colorant pigment, such as for example a white colored titanium dioxide pigment. The dual phased tire sidewall rubber composition is prepared by a phase mixing process comprised of pre-blending said butyl-type rubber and EPDM rubber together with said precipitated silica reinforcing filler to form a pre-mix thereof, and thereafter mixing therewith said nanocomposite as a pre-formed blend of natural rubber and exfoliated clay platelets.

    摘要: This invention relates to preparation of rubber compositions comprised of EPDM and conjugated diene-based elastomer, particularly including cis 1,4-polyisoprene rubber, and particularly natural cis 1,4-polyisoprene rubber, blends and pneumatic rubber tire with an outer, visible sidewall layer of a rubber composition comprised of such rubber composition. For such preparation, a combination of at least two diverse EPDM elastomers is used together with a phase mixing process comprised of sequential phase mixing or parallel phase mixing in the sense of reinforcement filler and sulfur curatives.

    摘要: The invention relates to a tire having a rubber tread of a circumferentially zoned tread including stratified lateral tread zones. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of an intermedial zone positioned between and two stratified lateral tread zones. The intermedial and stratified lateral zones are comprised of rubber compositions having differentiated rebound physical properties. The intermedial rubber zone, or layer, overlays a tread base rubber layer and underlies the lateral tread layer zones. The lateral tread zones are stratified in a sense of being separated from each other and also separated from the from the tread base rubber layer by the intermedial rubber layer. The stratified lateral tread zones are peripheral tread zones, or layers.
