Title: Rubber laminate

Abstract: Disclosed is a rubber laminate containing an unvulcanized fluororubber composition comprising: (A) fluororubber comprising a terpolymer containing 50 to 60 mol % of a constitutional unit derived from vinylidene fluoride, 20 to 30 mol % of a constitutional unit derived from tetrafluoroethylene, and 10 to 30 mol % of a constitutional unit derived from hexafluoropropene; (B) an oxide and/or hydroxide of a divalent metal; (C) a polyhydroxy aromatic compound; (D) a 2-substituted-4,6-dithiol-s-triazine derivative; (E.sub.1) a quaternary phosphonium salt or a tetraalkyl ammonium salt; (E.sub.2) 1,8-diazabicyclo[5.4.0]undecene-7 (salt); and (E.sub.3) a 5-substituted-1,5-diazabicyclo[4.3.0]-5-nonene (salt). In this rubber laminate, the fluororubber layer and the NBR layer are firmly vulcanization-bonded to each other without impairing various excellent characteristics of the fluororubber constituting the rubber layer.
