Patent ID: 8609232

Claim:
A low permeability rubber laminate comprising (A) at least one low permeability resin layer having an average thickness d of 0.05 μm<d<5 μm containing an ethylene vinyl alcohol copolymer (EVOH) having an air permeation coefficient at 30° C., determined according to JIS K7126, of 0.5×10 −12 cc·cm/cm 2 ·sec·cmHg or less and having an ethylene component ratio of 20 to 50 mol % and a degree of saponification of 90% or more and (B) at least one diene-based rubber composition layer containing at least one diene-based rubber selected from the group consisting of natural rubbers (NR), isoprene rubbers (IR), butadiene rubbers (BR) and styrene-butadiene copolymer rubbers (SBR) and 1 to 25 parts by weight, based upon 100 parts by weight of the diene-based rubber, of a silane-based coupling agent, as a bonding agent strength improver with the EVOH, having a functional group capable of reacting with a rubber and having an alkoxysilyl group, wherein said rubber composition contains, as a filler, only carbon black.
