Abstract

PURPOSE:To prevent the damage of a gasket through improvement of sliding ability between a gasket and a joining surface and reduction of a stress generated on the joining surface of the gasket by covering the surface of a metallic sheet, in order, with a chromate film, an adhesive layer, a rubber layer, and a molybdenum disulfide layer. CONSTITUTION:A gasket used in an engine for an automobile is formed such that the surface of a metallic sheet 1 is covered with a chromate film 2 and the chromate film is covered with an rubber adhesive as primer to form an adhesive layer 3. A heat resistant rubber layer 4, such as NBR and fluororubber, is adhered in a given thickness for covering through the medium of the adhesive layer 3 and further, a molybdenum disulfide layer 5 is adhered as a lubricant thereon for covering. This constitution causes improvement of sealing performance between a gasket and a joining surface through the presence of the rubber layer 4, improvement of sliding ability between the gasket and the joining surface, and prevention of the damage of the gasket through reduction of a stress generated on the joining surface of the gasket.

固着状態になり易い。When a gasket is manufactured from the rubber-coated metal obtained by the above-mentioned manufacturing method, the outer surface of this gasket is covered with a rubber layer, and therefore this gasket is used as a cylinder head gasket. When used, the joint surface between the cylinder block and the cylinder head and the gasket are likely to become stuck.

あった。However, the cylinder block and the cylinder head change greatly in temperature during repeated operation and stop of the engine, and as a result, the joint surface with the gasket is displaced due to a difference in expansion coefficient or the like. When the surface is a rubber layer, there is a problem in that the frictional resistance is large and it is difficult to slip, so it is difficult to absorb the stress generated in the joint surface, and the gasket is easily damaged.
