A silica reinforced solventless adhesive composition or cushion comprises a blend of rubber, silica, a silica coupling agent, an optional tackifier, and low or nil amounts of carbon black. The elastomeric adhesive composition can be utilized with various other rubber layers to adhere a cured or uncured tire tread to a cured tire casing. The elastomeric adhesive composition has good blowout resistance and a very low, final blowout test temperature.

Silica reinforced solventless elastomeric adhesive compositions

This invention relates to curable rubber compositions containing a fullerene form of carbon which is used as a reinforcing agent in the rubber compositions, the fullerene form of carbon being used in place of at least a portion of, or in addition to, the normally used forms of carbon black reinforcement additives. The invention particularly relates to tires having treads composed of such rubber composition(s). The fullerenes may optionally have surface modifications such as partial or complete hydrogen or functional group substitution. The fullerene form of non-conventional carbon reinforcement of rubber composition(s) may exist as discrete particles, aggregates of particles and/or agglomerates. The carbon fullerene has a lower specific gravity than conventional carbon black, thereby allowing a reduced weight tire or other article made from the rubber compound(s) for comparable volumes of carbon black used.

Use of fullerene carbon in curable rubber compounds

An elastomeric adhesive composition or cushion which binds various elastomeric layers together is solventless and comprises a blend of a bis-imide compound, one or more elastomers, and a tackifier. The elastomeric adhesive has strong blowout protection and can be utilized to form a laminate of a buffed cured tire carcass carcass to a cured or uncured tire tread.
