The invention discloses a composite rubber material specially used for tyre inner tubes. The composite rubber material comprises natural rubber, brominated butyl rubber, modified kaolinite, nano calcium carbonate, nano titanium dioxide, zinc oxide, stearic acid, sulphur, dicumyl peroxide, 2-(4-morpholinyl dithio)benzothiazole, organic silicon-acrylic ester rubber particle, methyl methacrylate-butadiene-styrene copolymer, lanthanum diethyldithiocarbamate, cobalt lanthanum glycine dithiocarbamic acid, accelerant M, accelerant CZ, an antioxidant, and a plasticizer; wherein the modifying agent of modified kaolinite is one or a mixture of ingredients selected from a bis-(triethoxysilylpropyl) tetrasulfide, a bis-(triethoxysilylpropyl) disulphide, and 3-propionyl sulpho-1-propyl-trimethoxy silane. The composite rubber material is excellent in mechanical properties, heat resistance, and air impermeability, and is long in service life as tyre inner tubes.
