Metal gasket for marine engine |
摘要 |
A metal gasket is made up of a backing material made of stainless steel, a galvanizing film is formed on a surface of the backing material, and a sealing rubber film is formed on a surface of the galvanizing film. In one embodiment a silane coupling type vulcanizing adhesive is applied to the surface of the galvanizing film and heated at a temperature of 100° C. to 200° C. for a prescribed period to generate a zinc oxide film on the surface of the galvanizing film and to bake the silane coupling type vulcanizing adhesive. Vinylidene fluoride type rubber containing a polyol type vulcanizing agent can be calcined onto its surface to form the sealing rubber film. The metal gasket can be provided on a mating surface of a cylinder head and a cylinder body of an engine provided in an outboard motor.
