<P>PROBLEM TO BE SOLVED: To provide a nitrile rubber-metal laminated gasket material superior in water resistance, LLC resistance and heat resistance without performing harmful coating-type chromate treatment onto metal, and free from peeling-off of the laminated gasket, for example, even in a water-resistant testing method under consideration of actual use environment of an engine cylinder head gasket, in forming the rubber-metal laminated gasket material composed of a complex of stainless steel plate and nitrile rubber. <P>SOLUTION: This nitrile rubber-metal laminated gasket material is formed by successively laminating a surface treatment agent layer including organic metallic compound and silica, a phenol resin-containing vulcanized adhesive agent layer, a nitrile rubber layer, and further preferably an anti-adhesion layer on the stainless steel plate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
