Abstract
Official abstract text for this publication.
Disclosed is a rubber metal laminate comprising metal, an adhesive layer and a perfluoroelastomer layer, the perfluoroelastomer layer being formed from a vulcanizate layer of a blend comprising 2 to 10 parts by weight of a vinylidene fluoride-chlorotrifluoroethylene copolymer, based on 100 parts by weight of a perfluoroelastomer. The rubber metal laminate of the present invention can effectively improve the interlayer adhesion of the perfluoroelastomer to the metal and pockmarked surface (the state that crater-like irregularity is formed) of the perfluoroelastomer layer laminated on the metal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber metal laminate comprising metal, an adhesive layer formed on the metal and a perfluoroelastomer layer formed on the adhesive layer, the perfluoroelastomer layer being formed from a vulcanizate layer of a blend comprising 2 to 5 parts by weight of a vinylidene fluoride-chlorotrifluoroethylene copolymer elastomer, based on 100 parts by weight of a perfluoroelastomer wherein the perfluoroelastomer is a copolymer of perfluorovinyl ether and at least one of tetrafluoroethylene and hexafluoropropene, the vulcanizate layer further comprises a filler. 2. The rubber metal laminate according to claim 1 , wherein in the vinylidene fluoride-chlorotrifluoroethylene copolymer elastomer, 10 to 50 mol % of chlorotrifluoroethylene is copolymerized. 3. The rubber metal laminate according to claim 1 , wherein the perfluoroelastomer layer is a peroxide-crosslinked product layer of the blend.
