Abstract

PURPOSE:To provide a heat resistant gasket with improved durability and abrasion resistance, by turning a graphite sheet including metal filaments and a flat wire mesh put together around a core bar and then by pressing the same into a predetermined shape. CONSTITUTION:A graphite sheet with metal filaments 1 in which the metal filaments 2 are uniformly distributed is put together with a flatten wire mesh 3 and the same are turned around a core bar 4 and then pressed into a heat resistant gasket of a predetermined shape. Since the wire mesh inside the gasket serves as a reinforcing material and the metal filaments are exposed on the surface, the produced gasket has good abraision resistance and maintains sealing performance for a long time even if the same is subjected to a high temperature.

As disclosed in Japanese Patent No. 54-76759, a graphite sheet was made longer than both ends of a wire mesh, wound around a core metal with the graphite sheet outside, and then compression molded into a predetermined shape. Since the surface is covered only with graphite, if it is used in a way that involves heavy sliding, the graphite on the sliding surface will wear out or break off, making it weak in 11i11 durability and surface 1 abrasion, and the graphite on the sliding surface will adhere to the spherical surface of the contact member. However, when the two graphites rub against each other, a sliding noise is generated.Sliding noise occurs when the engine is idling.
,<There was a drawback that the interior of the listening car +1i11 could not be made quiet.The present invention was designed to eliminate the drawbacks of the conventional method by using 4-lament-containing regraphite 7-gold rice.Next. [Appendix] The present invention will be explained with reference to the drawings. 1 is a graphite sheet containing metal filaments in which gold wire filaments 2 are evenly mixed. Heat-resistant thin metal wires such as fine stainless steel wires having a diameter of 0.15-0.35φ are knitted into a knitted material and polymerized into a flattened wire mesh 3 to form a core. According to the present invention, the wire mesh inside the heat-resistant gasket acts as a reinforcing material and the metal filament is always exposed on the surface, so the exhaust pipe joint When used in applications, it is slidable, has good wear resistance, and is filled with graphite, so it can maintain sealing performance for a long period of time even when exposed to high-temperature exhaust gas. Since it does not stick, there is no sliding noise.
