The present invention relates to a method for forming a surface pressure supplementary layer on the surface (joining surface) of a gasket for internal combustion engine assembly in order to improve the sealing performance of the gasket. Spraying or printing methods are generally used as conventional layering methods, but in both of these methods, the materials constituting the surface pressure supplementary layer are liquids, so local exhaust equipment must be installed in the workplace, etc. As a result, it requires a huge amount of capital for capital investment, and is not necessarily suitable for high-mix, low-volume production systems, which is a factor in high product costs. Furthermore, since the material to be layered is a liquid, even if it is deposited on the gasket surface to the required thickness, it will run and sag, and as a result, it will not be possible to obtain a replenishment layer with the specified width and thickness. The expected effect on gasket sealing performance cannot be obtained, and depending on the method, protrusion may occur, and in any case, the layering method itself requires a certain level of skill. The present invention was created with the aim of providing a product that is suitable for a variety of small quantity production methods, does not require various equipment, and is inexpensive. The drawing shows a product obtained by the method of the present invention, in which a contact pressure replenishing layer 3 is added to the insufficient contact pressure area on the upper and lower surfaces 2, 2 of the gasket body 1 by electrostatic printing. , 3, ... are arranged in layers. In addition, 4 in the figure shows a water hole, 5 an oil hole, 6 a cylinder hole, and 7 a grommet. As an example of layering the above-mentioned surface pressure supplementary layer 3, an example will be described in which an acrylic resin having an average particle diameter of 30 to 50 μm is used as a constituent material. A high DC voltage in the range of 1 kV to 12 kV was applied between the stainless steel screen and the gasket body, the high DC voltage was controlled, and the high voltage was set for each gasket under conditions that would not cause the resin to scatter on the gasket surface. After the resin is electrodeposited on the gasket, the electrodeposited resin particles are melted in a drying oven at 150°C to 180°C for about 15 minutes, and the resin is fixed on the gasket surface to complete electrostatic printing. In addition, as a function investigation of the gasket with the surface pressure replenishment layer formed using the electrostatic printing method, we conducted a liquid resistance test (liquid resistance test table-1) and found that the surface pressure replenishment layer was resistant to oil, fuel, and antifreeze. No significant deterioration was observed, and as a result of the compression test (surface pressure of 500 kgf/cm 2 ), the test results showed that the surface pressure supplementary layer did not break and had sufficient functionality as a surface pressure supplementary layer. judged by. In particular, when the gasket is a metal gasket made of a metal plate, a surface pressure supplementary layer that can withstand high surface pressure can be obtained.

According to the present invention, when forming a surface pressure supplementary layer with a wide width of 5 to 10 mm, especially when the gasket is made of a low-density material such as asbestos, the resin is absorbed into the gasket before it hardens. , it is not possible to obtain a surface pressure replenishment layer with a uniform thickness, whereas with electrostatic printing, the powder is melted and fixed in a short time, so by selecting the particle size of the resin, it is possible to A surface pressure replenishment layer with a uniform thickness can be obtained with less absorption into
Since the surface pressure supplementary layer provided according to the present invention easily forms a hard layer, the layer does not break when pressure is applied to the surface pressure supplementary layer, and the surface pressure can be easily ensured. Moreover, it is possible to provide inexpensive products without being restricted by various laws and without requiring incidental equipment.
