    摘要: It has been unexpectedly found that certain blends of styrene-butadiene rubber and platey filler exhibit both good gas barrier properties and good tensile fatigue properties. These blends accordingly have the requisite characteristics for a tire innerliner material. They offer the advantage of being much less expensive than halobutyl rubbers which can be employed for the same purpose. The present invention more specifically discloses a pneumatic tire having an integral innerliner wherein said innerliner is comprised of a blend of (1) from about 40 phr to about 99 phr of a first styrene-butadiene rubber having a bound styrene content of about 15 percent to about 30 percent, (2) from about 1 phr to about 60 phr of a high styrene content styrene-butadiene rubber having a bound styrene content of about 40 percent to about 60 percent, and (3) from about 40 phr to about 125 phr of platey filler. The subject invention also discloses a pneumatic tire having an integral innerliner wherein said innerliner is comprised of (1) a styrene-butadiene rubber having a bound styrene content of about 15 percent to about 30 percent, and (2) from about 125 phr to about 200 phr of platey filler.

    摘要: The invention relates to a tire having at least one component comprised of a rubber composition which contains pre-hydrophobated precipitated silica aggregates. Such tire component may be, for example although not limited to, a tire tread, sidewalls and/or sidewall insert. Such pre-hydrophobated precipitated silica aggregates are contemplated as being prepared, for example, by treatment of a colloidal silica with a combination of both an organomercaptosilane and an alkylsilane.

    摘要: A pneumatic tire and an innerliner for use in a pneumatic tire are provided by the invention. The innerliner comprises a multilayer structure including a barrier layer and an adhesive layer. The barrier is a blend of high chlorine content chlorinated polyethylene elastomer and low chlorine-content chlorinated polyethylene elastomer. The adhesive can include a nitrile rubber composition or an ultra high molecular weight elastomer. The present invention more specifically discloses a pneumatic tire comprising a carcass and an innerliner, said innerliner comprising a multilayer structure including a barrier layer and an adhesive layer, the barrier layer comprising a blend of high chlorine content chlorinated polyethylene elastomer and low chlorine content chlorinated polyethylene elastomer, the high chlorine content chlorinated polyethylene elastomer having a chlorine content of between about 35 percent to about 45 percent and the low chlorine content chlorinated polyethylene polymer having a chlorine content of between about 25 percent to about 35 percent, wherein the high chlorine content polyethylene has a chlorine content which is at least 5 percentage points higher that the chlorine content of the low chlorine content polyethylene; the adhesive layer comprising a polymer composition for adhering the barrier layer to said rubber carcass; and wherein the innerliner provides an oxygen permeability of less than 250 cc-mil/100 in2-atm-day at 65° C. and good cold flexibility at −40° C.
