摘要： A production method for a laminate of a fluorosilicone rubber and a silicone rubber is provided. The production method comprises the following steps: (1) curing a fluorosilicone rubber composition comprising: (A) an organopolysiloxane having alkenyl groups and fluoroalkyl groups, (B) an organopolysiloxane having silicon atom-bonded hydrogen atoms and fluoroalkyl groups, and (C) a hydrosilylation reaction catalyst; (2) laminating a silicone rubber composition comprising: (D) an organopolysiloxane having alkenyl groups and not having fluoroalkyl groups, and (E) an organic peroxide on a surface of a fluorosilicone rubber produced in step (1) above; and (3) curing a silicone rubber composition layer in a laminate produced in step (2) above. A laminate in which a fluorosilicone rubber layer and a silicone rubber layer are adhered well using a hydrosilylation reaction curable fluorosilicone rubber composition is produced.
