を損なうという欠点があった。Furthermore, in Saki'ko's 52nd March 15th, the applicant further stated that an uneven pattern formed on a thin metal plate consisting of a gypsum mixture made by mixing an appropriate amount of water and a resin emulsion with hemihydrous gypsum, and a cement latex mixture. An application has been filed for a coating method.
However, when forming a thick uneven pattern on these thin metal plates, the expansion and contraction of the coating material cannot follow the large difference in expansion and contraction due to changes in temperature, which is a characteristic of metals. In the long term, the paint film peeled off from the thin metal plate, resulting in an unsightly appearance.

ることを目的とする。In order to eliminate the above-mentioned drawbacks, the present invention uses a hot-melt adhesive with excellent adhesiveness and thermoplasticity as a material for forming the uneven pattern coating film, and uses a hot-melt adhesive with excellent adhesiveness and thermoplasticity to form a beautiful variety of coatings with strong adhesiveness on thin metal plates. It is an object of the present invention to provide a method for easily forming a concavo-convex pattern.

ることが望ましい。Next, a method for forming an uneven pattern according to the present invention will be explained. That is, fine particles of hot melt adhesive are sprinkled on a preheated thin metal plate 1 at appropriate intervals so that the fine particles form a lumpy distribution, and then an upper part is applied to the string particles. The pongee grains are melted by heating, and then adhered to a thin metal plate and cooled and solidified as it is, or while being pressed to form an uneven pattern coating film 2, and then a full makeup with the uneven pattern coating 2 distributed thereon. A decorative coating film 3 made of paint or the like is applied to the surface to complete the uneven pattern. Further describing this method in detail, the hot melt adhesive that is the material of the uneven pattern coating film 2 used in the present invention is, for example, EVA (a copolymer of vinyl acetate and ethylene).
It is made of heat-meltable resin and has a softening point of 100.
It is desirable to use one having a melting point of 180 to 220 oC or more.

である。The hot melt adhesion agent is finely granulated to an appropriate size, and the size of the particles and the density at which they are sprinkled onto the thin metal plate 1 are determined by the shape of the required uneven pattern.
FIG. 2 is a schematic diagram of an apparatus for carrying out the method according to the invention.

成する。First, the thin metal plate 1 is fed in the direction of the arrow over the comperor 4, passes through the subheating furnace 5, and is heated here to a temperature of 10,000 or more. Next, from the lower end slit 8 of the hopper 7 containing the string grains 6 of hot melt adhesive, the fine grains 6 are dropped onto the thin metal plate 1 one by one to be scattered.
The thin metal sheet 1 is then fed into a melting furnace 9. In addition, the atmospheric temperature of the melting furnace 9 is 250 to 30
Since the temperature is set to 0oo and is higher than the melting point of the hot melt adhesive, the pongee grains 6 are completely melted at the exit of the melting furnace 9 and are distributed on the thin metal plate 1 in the form of drips. Even if this is left to cool as it is, the uneven pattern coating film 2 will be formed.
After passing through the melting furnace 9, the tops of the drop-shaped molten pongee grains 6 are held down with a roll 10 that has been pre-cooled by passing through a cooling water 11, and the tops of the drop-shaped molten pongee grains 6 are flattened and solidified to form a "studded trowel pattern-like uneven pattern coating". Form a film 2. Next, this coating film 2
A decorative coating film 3 is formed by applying paint to the entire decorative surface including the decorative surface.
