The rubber composition contains, relative to 100 parts by mass of the rubber ingredient (A) therein, from 1 to 9 parts by mass of carbon black (B) and from 80 to 150 parts by mass of a layered or platy clay mineral (C).
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition containing, relative to 100 parts by mass of the rubber ingredient (A) therein, from 1 to 9 parts by mass of carbon black (B) and from 80 to 150 parts by mass of a layered or platy clay mineral (C) wherein the rubber ingredient (A) comprises 80 to 100% by mass of a butyl-based rubber and at most 20% by mass of a dienic rubber. 2. The rubber composition according to claim 1 , wherein the rubber ingredient (A) comprises 100% by mass of a butyl-based rubber. 3. The rubber composition according to claim 2 , wherein the rubber ingredient (A) comprising a butyl-based rubber is at least one selected from butyl rubber, bromobutyl rubber and chlorobutyl rubber. 4. The rubber composition according to claim 1 , wherein the iodine adsorption of the ingredient (B), carbon black is at most 50 mg/g and the dibutyl phthalate absorption thereof is at most 125 ml/100 g. 5. The rubber composition according to claim 1 , wherein the aspect ratio of the ingredient (C), layered or platy clay mineral is from 2 to 200. 6. The rubber composition according to claim 1 , wherein the ingredient (C), layered or platy clay mineral contains kaolinitic clay or sericitic clay. 7. The rubber composition according to claim 1 , wherein the ingredient (C), layered or platy clay mineral contains a hydrated composite of silica and alumina. 8. A pneumatic tire using the rubber composition of claim 1 as the inner liner therein.
