Tire Innerliner With Carbon Black Blend

Abstract

A tire comprising an innerliner, where the inner-liner includes a rubber, a first carbon black having a statistical thickness surface area of at least 50 m 2 /g, and a second carbon black having a statistical thickness surface area of at most 45 m 2 /g.

What is claimed is: 
     
         1 . A tire comprising an innerliner, where the innerliner includes a rubber, a first carbon black having a statistical thickness surface area of at least 50 m 2 /g, and a second carbon black having a statistical thickness surface area of at most 45 m 2 /g. 
     
     
         2 . The tire of  claim 1 , where the first carbon black and the second carbon black are dispersed within a vulcanized rubber matrix. 
     
     
         3 . The tire of  claim 1 , wherein the innerliner has a thickness of less than or equal to 0.25 cm. 
     
     
         4 . The tire of  claim 1 , wherein the innerliner has a thickness of less than or equal to 0.20 cm. 
     
     
         5 . The tire of  claim 1 , wherein the innerliner further includes clay. 
     
     
         6 . The tire of  claim 5 , wherein the clay is a layered clay. 
     
     
         7 . The tire of  claim 5 , where the clay is selected from the group consisting of montmorillonite, hectorite, nontrite, beidellite, volkonskoite, saponite, sauconite, sobckite, sterensite, and sinfordite. 
     
     
         8 . The tire of  claim 1 , wherein the innerliner includes from about 2 to about 50 parts by weight of the first carbon black per 100 parts by weight rubber, and includes from about 5 to about 60 parts by weight of the second carbon black per 100 parts by weight rubber. 
     
     
         9 . The tire of  claim 1 , wherein the innerliner includes from about 5 to about 40 parts by weight of the first carbon black per 100 parts by weight rubber, and includes from about 15 to about 55 parts by weight of the second carbon black per 100 parts by weight rubber. 
     
     
         10 . The tire of  claim 1 , wherein the innerliner includes from about 10 to about 30 parts by weight of the first carbon black per 100 parts by weight rubber, and includes from about 20 to about 50 parts by weight of the second carbon black per 100 parts by weight rubber. 
     
     
         11 . A tire comprising an innerliner, where the innerliner includes a rubber, a first carbon black having an average particle size of less than 40 nm, and a second carbon black having an average particle size of greater than 40 nm. 
     
     
         12 . The tire of  claim 11 , where the first carbon black and the second carbon black are dispersed within a vulcanized rubber matrix. 
     
     
         13 . The tire of  claim 11 , wherein the innerliner has a thickness of less than or equal to 0.25 cm. 
     
     
         14 . The tire of  claim 1 , wherein the innerliner has a thickness of less than or equal to 0.20 cm. 
     
     
         15 . The tire of  claim 11 , wherein the innerliner further includes clay. 
     
     
         16 . The tire of  claim 15 , wherein the clay is a layered clay. 
     
     
         17 . The tire of  claim 15 , where the clay is selected from the group consisting of montmorillonite, hectorite, nontrite, beidellite, volkonskoite, saponite, sauconite, sobckite, sterensite, and sinfordite. 
     
     
         18 . The tire of  claim 15 , wherein the innerliner includes from about 2 to about 50 parts by weight of the first carbon black per 100 parts by weight rubber, and includes from about 5 to about 60 parts by weight of the second carbon black per 100 parts by weight rubber. 
     
     
         19 . The tire of  claim 15 , wherein the innerliner includes from about 5 to about 40 parts by weight of the first carbon black per 100 parts by weight rubber, and includes from about 15 to about 55 parts by weight of the second carbon black per 100 parts by weight rubber. 
     
     
         20 . The tire of  claim 15 , wherein the innerliner includes from about 10 to about 30 parts by weight of the first carbon black per 100 parts by weight rubber, and includes from about 20 to about 50 parts by weight of the second carbon black per 100 parts by weight rubber.
