Abstract
A rubber laminate comprising at least one sheet of a fluorine-containing rubber and at least one sheet of a nitrile/butadiene rubber wherein either one of the rubber sheets is incorporated by mixing with an epoxy resin and the other of the rubber sheets is incorporated by mixing with a curing agent for the resin which is produced by assembling the sheets under pressure in the presence of a curing temperature. The resulting rubber laminate has an excellent impermeability to liquids and is useful for preparing various devices or vessels for transferring or treating organic solvents and oils, e.g. a hose for gasoline.
Claims16
A hose possessing excellent impermeability to liquids which comprises a rubber laminate consisting essentially of at least one sheet of a fluorine-containing rubber and at least one sheet of a nitrile/butadiene rubber wherein either one of said rubber sheets is incorporated with an epoxy resin and the other one of said rubber sheets is incorporated with a curing agent for said resin, said sheets being directly adhered to each other in a cured state.
A rubber laminate which comprises at least one sheet of a fluorine-containing rubber and at least one sheet of a nitrile/butadiene rubber wherein either one of said rubber sheets is incorporated, by mixing, with an epoxy resin and the other of said sheets is incorporated, by mixing, with a curing agent for said resin, said sheets being directly adhered to each other in a cured state.
A process for producing a rubber laminate, which comprises providing a sheet of fluorine-containing rubber and a sheet of nitrile/butadiene rubber, one of said sheets having mixed therein an epoxy resin and the other of said sheets having mixed therein a curing agent for said epoxy resin, assembling said sheets so as to form a laminate arrangement and applying pressure to said rubber laminate arrangement in the presence of a curing temperature so as to produce said rubber laminate.
