Document Type and Number:
Japanese Patent JP5780369
Kind Code:
B2
Abstract:
A rubber laminate comprising an unvulcanized carboxyl group-containing acrylic rubber layer and an unvulcanized polyol-crosslinkable fluororubber layer that are integrally bonded by vulcanization; the unvulcanized carboxyl group-containing acrylic rubber layer comprising an aromatic polyvalent amine compound; 1,8-diazabicyclo[5.4.0]undecene-7, 1,5-diazabicyclo[4.3.0]nonene-5, or a salt thereof; and a guanidine compound; the guanidine compound being used at a ratio of 3 to 8 parts by weight, preferably 4 to 6 parts by weight, based on 100 parts by weight of unvulcanized carboxyl group-containing acrylic rubber. The rubber laminate has excellent scorch stability of the unvulcanized acrylic rubber layer and excellent adhesion.
