The invention discloses a tyre inner liner rubber composition. The tyre inner liner rubber composition comprises brominated butyl rubber, 1742 butyl rubber, carbon black N660, diatomite, magnesium oxide, stearic acid, 4m2 zinc oxide, 2 resin, naphthenic oil, a promoter DM and 7020 sulphur. Through use of diatomite in the inner liner rubber composition, the tyre inner liner rubber composition solves the problem that the original inner liner is broken easily in calendaring and has poor viscosity in molding and bonding and has greatly high viscosity. In molding, viscosity between the inner liner and seam allowance rubber is obviously improved.
