<p>A rubber laminate which is obtained by integrally bonding, by vulcanization, an unvulcanized carboxyl group-containing acrylic rubber layer and an unvulcanized polyol-crosslinkable fluorine rubber layer. The unvulcanized carboxyl group-containing acrylic rubber layer contains: an aromatic polyvalent amine; 1,8-diazabicyclo[5.4.0]undecene-7, 1,5-diazabicyclo[4.3.0]nonene-5, or a salt of 1,8-diazabicyclo[5.4.0]undecene-7 or 1,5-diazabicyclo[4.3.0]nonene-5; and a guanidine compound. The guanidine compound is used in an amount of 3-8 parts by weight, preferably 4-6 parts by weight per 100 parts by weight of the unvulcanized carboxyl group-containing acrylic rubber. The unvulcanized acrylic rubber layer of this rubber laminate has excellent scorching stability and bondability.</p> |
