The present invention relates to a method for manufacturing a display body attached to a water pipe, a gas pipe opening/closing switch, an electric circuit switch, etc., to display its use and operation method. In recent years, efforts have been made to ensure that the parts of faucet fittings that display letters and symbols that indicate their intended use and operating instructions will not get dirty or peel off, and will remain easy to read and aesthetically pleasing. Many things started to appear. That is, a recessed part is formed in a part of the metal part that is the main display, a sheet representing the necessary characters, symbols, designs, etc. is placed on the bottom of the part, and a transparent synthetic resin is placed inside the recessed part. For example, a method for inserting and hardening the material has been proposed in Japanese Utility Model Application Publication No. 14134/1983. However, when we consider the case where ordinary paper is used as the material for the sheet representing the above display, we find that paper does not conform to the bottom of the recessed part or warps, etc., and that the hardened transparent synthetic resin There is a drawback that the display appears distorted in the . In addition, even if you select and use a sheet made of a material other than paper that does not cause distortion, air will accumulate between it and the bottom of the recessed part, and when the transparent synthetic resin is inserted and cured, it will remain as air bubbles and spoil the aesthetic appearance. . Furthermore, if the back side of the sheet is coated with an adhesive in advance, it is difficult to place the sheet properly in the limited space of the recessed part, resulting in extremely poor workability. Another method is to apply an adhesive to the recessed part and bring the sheet into contact with it, but due to the difference in compatibility between the adhesive and the transparent synthetic resin to be filled, It has the disadvantage of producing a striped pattern during curing. The properties of the transparent synthetic resin proposed in Utility Model Application Publication No. 53-14134 have not been clarified, or various chemical, physical, and mechanical properties are required. For example, the viscosity needs to be low in order to improve workability and to ensure that the air contained during filling does not remain as bubbles during curing and that the bubbles can easily float up and escape. It must be paste-like to the extent that it can be swollen to a high degree, and it must also have properties that do not cause wrinkles on the surface when hardened, so it does not harden at room temperature and has enough time to harden when heated. On the other hand, curing requires contradictory properties: it must be carried out quickly and at low temperatures in order to avoid altering the properties of the sheet. Furthermore, the above-mentioned transparent synthetic resin is required to have excellent transparency after curing, high heat resistance, chemical resistance, and water resistance, not be easily scratched by nails, etc., and furthermore not to change over time, such as yellowing. The present invention solves this problem, and satisfies the properties required of the transparent synthetic resin by using an epoxy resin and a polyoxypropylene amine resin as the transparent synthetic resin. In addition, the present invention removes the residual air by dropping a transparent synthetic resin having the same properties as the above-mentioned transparent synthetic resin onto the bottom surface of the sheet before placing it on the bottom of the recessed part. When pressed against the bottom, a portion of the resin oozes out above the surroundings of the sheet to press the edge of the sheet against the bottom, preventing the sheet from warping and positioning the sheet accurately. An embodiment of the method of the present invention will be described in detail below with reference to the drawings. A cylindrical recessed portion 2 as shown in the first figure is bored in the center of the upper surface of the display main body 1 made of metal. The area of this recessed part 2 increases as it faces inward,
The inner circumferential surface 3 is enlarged into a conical shape. Subject 1
The outer circumferential portion 4 of the upper surface is inclined at a steep angle so as to become higher toward the center, and its tip faces the recessed notch portion 2, and the edge 5 is sharply pointed. As shown in the first figure, a resin 7, which is the same as the transparent synthetic resin described below, is dropped onto the center of the bottom surface 6 of the recessed portion 2. Next, as shown in the second figure, a sheet 8 representing a display is inserted into the recessed portion 2 with its bottom facing down, and the center of its bottom is brought into contact with the resin 7. When the center of the sheet 8 is pushed downward with a finger and the finger is gradually slid outward as indicated by the arrow in FIG. 2, the resin 7 is stretched outward between the sheet 8 and the bottom surface 6. Thus, as shown in the third figure, the sheet 8 is placed on the bottom surface 6.
When the resin 7 comes into complete contact with the sheet 8, the resin 7 spreads uniformly over the entire surface without leaving any residual air between the bottom surface of the sheet 8 and the bottom surface 6 of the recessed part 2, and the excess material is released from the surrounding area of the sheet 8. The excess resin that swells up on the upper side of the periphery presses the periphery of the sheet and holds the sheet 8 in an accurate position in close contact with the bottom surface 6. In this manner, the transparent synthetic resin 9 is filled into the recessed portion 2 as shown in the fourth figure. This transparent synthetic resin 9 is a mixture of a main agent made of epoxy resin and a curing agent made of polyoxypropylene amine in a ratio determined by the epoxy equivalent and amine value, respectively. is an aliphatic primary di- or triamine derived from polypropylene glycol or triol. This polyoxypropylene amine has four grades: D-230, D-230,
-400, D-2000 and T-403, the symbol D represents the diamine type and the symbol T represents the triamine type, and the number added after it represents the approximate average molecular weight. Its chemical formula is

-2000, n≒33.1). Also, the chemical formula of T-403 is (x+y+z≒5.3). Any epoxy resin can be used.
Use one with a low viscosity of 9000 CPS or less. When the main body 1 filled with the resin 9 is heated to 80° C., the resin hardens in about 2 hours, and the central portion becomes spherically raised to form a convex lens-shaped transparent synthetic resin as shown in FIG. According to the present invention, the sheet representing the display is accurately positioned and fixed to the bottom surface of the recessed part using resin, and since the resin is the same resin as the transparent resin filled and solidified on top of the sheet, both It has good adhesion and does not produce a striped pattern during curing. In addition, in the present invention, since epoxy resin and polyoxypropylene amine resin are used as the transparent synthetic resin, the proportion of primary amine is high, so not only is the viscosity low and workability is good, but also the distance between the sheet and the bottom surface is low. Or, even if air remains in other parts, it will completely escape upwards, and when heated further, the viscosity will temporarily decrease further and there will be time for it to harden. The air bubbles will escape and no air bubbles will remain in the molded product. In addition, the above resin cures quickly at relatively low temperatures, so it does not change the quality of the sheet, and after curing, it has excellent transparency, water resistance, heat resistance, chemical resistance, flexibility, and toughness, and has excellent properties such as nails, etc. It is not easily scratched and does not easily change over time. Furthermore, in the present invention, when the sheet is brought into contact with the bottom surface of the recessed part, the excess transparent synthetic resin rises above the periphery of the sheet and presses the periphery of the sheet, thereby completely preventing the sheet from warping. This can be prevented.
