<P>PROBLEM TO BE SOLVED: To provide a vulcanized laminate with a rubber layer and a fluororesin layer firmly bonded together without treating their surfaces and using an adhesive. <P>SOLUTION: This laminate includes the rubber layer (A) and the fluororesin layer (B) laminated on the former. In addition, the rubber layer (A) is formed of a rubber composition for vulcanization, and contains epichlorohydrin rubber (a1), at least one kind of a chemical compound (a2) selected from a group composed of p-toluenesulfonate of 1,8-diazabicyclo(5.4.0)undecene-7 or 1,5-diazabicyclo(4.3.0)-nonene-5, a phenol salt, phenol resinate, orthophthalate, formate and octylate, a magnesium oxide (a3), silica (a4) and epoxy resin (a5). The fluororesin layer (B) contains a fluoropolymer (b1) with a copolymerization unit derived from chlorotrifluoroethylene. <P>COPYRIGHT: (C)2012,JPO&INPIT |
