を提供できるようにすることを目的とするものである。In recent years, as land and real estate prices have skyrocketed, houses have become more luxurious, and people are increasingly looking for high-class roofs with tiles made of copper plates or ceramics. Therefore, in order to meet these demands, tiles were soaked in glaze.
Some are made by firing this, others are made by applying adhesive to the surface to be decorated, coating the adhesive with copper powder, and then applying clear paint to the top surface. When forming tiles by applying glaze and firing, there was a problem that mortar could not be used because it was sensitive to heat, so copper or ceramic powder was attached to the tile material with adhesive. It requires many processing steps such as applying adhesive, applying copper powder, and applying clear paint, and requires a lot of effort.
(As mentioned above, the clear paint deteriorates quickly, so the copper powder peels off quickly and there is a problem with durability.) The present invention was proposed in view of the above problems. The purpose of the present invention is to provide a mortar tile that has excellent durability and has a luxurious feel.

At this time, the sprayed decorative surface of the dried tile material is formed into a rough surface with a finely wavy cross-sectional shape. Next, when copper is thermally sprayed onto the sprayed decorative surface of the tile material, the surrounding area of the molten copper particles will cool and gradually harden as they fly, but the inside will still be molten and soft. . When this is sprayed onto the finely corrugated rough surface of the thermal sprayed decorative surface, the molten copper particles bite into the uneven parts of the rough surface and are cooled.The molten particles shrink on cooling and form into the uneven parts of the rough surface. It digs in firmly, and the decorative surface of the tile material is painted copper-colored, as if it were made of copper plate. In this way, the molten copper particles that are cooled while biting into the irregularities of the finely corrugated rough surface of the thermal sprayed decorative surface are kept firmly fixed to the irregularities of the rough surface by cooling contraction. It is. In particular, if the cross-sectional shape of a rough surface consisting of minute irregularities or a continuous mountain shape is formed with an acute apex angle, the molten copper particles attached to the side slopes around the apex angle may be contaminated with other particles. Even if they come into contact with each other, the force acting on the molten copper particles is in a direction different from the direction in which the molten copper particles are trying to pull out, which prevents the copper particles fixed to the surface of the tile material from peeling off.

来るのは言うまでもないことである。The present invention will be explained below based on the drawings. FIG. 1 shows a perspective view of a mortar tile manufactured by the thermal spray decoration method for mortar tiles of the present invention, and reference numeral 1 in the figure indicates the mortar tile as a whole. This mortar tile I is first made by mixing cement, sand, and water in a predetermined ratio, then placing mortar between an upper mold and a lower mold (both not shown) in a press machine. The tile material 2 is formed by pressing the mold against the lower mold and dewatering and molding. Next, the shaped tile material 2 is dried and solidified. At this time, if a fine uneven pattern is applied to the upper mold for shaping the surface 2a of the tile material 2, the surface 2a of the dried tile material 2 will have fine unevenness as shown in FIG. A rough surface 3 with a continuous pattern is formed. In this way, a fine uneven pattern is formed on the surface, and a mist of copper is sprayed onto the surface (sprayed decorative surface) 2a of the dried tile material 2 using a thermal spraying device. This thermal spraying equipment melts copper wire onto metal wire using an arc.
Electric wire thermal spray equipment that uses compressed air to form a mist and spray it, or gas melt wire thermal spray equipment that melts copper wire using a high-temperature gas flame and sprays it into a mist using compressed air, or melts metal powder with a high-temperature flame and blows it away. Powder spray equipment is used. The molten copper particles 4, which are blown onto the surface 2a of the tile material 2 while being melted in this way, are cooled and gradually hardened as they fly as shown in Figure 3, but the inside is still molten. When this is blown onto the rough surface 3 of the surface 2a of the tile material 2, the molten copper particles 4 may pierce the tips of the uneven parts of the rough surface 3, or be blown densely into the valleys. surface 2a of tile material 2
A thin layer of copper metal is formed on the surface. When the molten copper particles 4 are cooled while being stuck to the tips of the uneven portions of the rough surface 3, the molten copper particles 4
is cooled and shrunk to a state where it firmly clings to the tips of the uneven portions of the rough surface 3, and is firmly fixed. In addition, molten copper particles 4 are sprayed in a thin layer in the valley.
The heat they possess causes them to fuse together, forming a relatively smooth layer. Here, the temperature of the molten particles 4 immediately after being thermally sprayed is quite high, but when it hits the surface 2a of the tile material 2, the results of experiments conducted by the present applicant show that the temperature of the molten particles 4 immediately increases due to the large heat capacity of the tile material 2. Since it is cooled, the temperature of the surface 2a of the tile material 2 rises only to about 150 degrees, and the temperature at which the mortar tile material 2 is damaged by heat is about 300 degrees.
It was found that there was no damage due to temperature rise. Also, the surface 2a of the tile material 2 on which the molten copper particles 4 are sprayed
If the apex angle θ of the uneven portion is made acute, even if another object comes into contact with the molten copper particles 4 attached to the rainforest surface, the force F acting on the molten copper particles 4 will be The surface 2 of the tile material 2 is different from the direction of the force f trying to pull it out.
This prevents the copper particles fixed to a from peeling off. In this way, when the molten copper particles 4 are cooled while biting into the tips of the uneven portions of the rough surface, the entire surface 2a of the tile material 2 is decorated in a copper color as if it were made of a copper plate. It is. The copper particles fixed on the surface 2a of the tile material 2 are oxidized with a chemical solution to generate a patina, or a clear paint is applied to the upper surface of the copper particles or the patina. In some cases, it is processed and shipped. In the above embodiment, the rough surface 3 of the surface 2a of the tile material 2 is formed by applying a fine uneven pattern to the upper mold of a press machine, but mortar is formed by pressing the mortar with a press machine. Sometimes, if a fine wire mesh such as a filter cloth or mesh is provided in the upper mold part that shapes the surface 2a'' of the tile material 2 and the water is dehydrated from this to form the rough surface 3, the mesh of the filter cloth or wire mesh is In addition to forming irregularities due to the shape, the solid lumps in the mortar are exposed to the thermal sprayed decorative surface by dehydration, which further improves the effect of fixing the thermal spray particles. Although copper is sprayed on the surface 2a, it goes without saying that other metals, ceramics, glass, and other materials can also be sprayed in substantially the same manner.
