Concavo-convex molded.

However, JP-A-58-140253
In the method of manufacturing a washing floor as described in Japanese Patent Publication, since a mold having irregularities on the mold surface is used, the cost of manufacturing the mold is high, and the finish of the natural stone-like washing floor is FR.
I cannot get out of the range of P products, and the cosmetic effect does not rise significantly.

Therefore, such Japanese Patent Laid-Open No. 58-1402
As a method for improving the method of manufacturing a washing floor described in Japanese Patent No. 53, a method of adhering a tile to a molded washing floor floor with an epoxy adhesive has been proposed.

[0006]

However, in the method of adhering the tile to the floor surface of the washing place with the adhesive as described above, it takes time to mix and knead the adhesive, and the adhesive is applied to adhere the tile. After that, a long time of 24-72 hours is required as the curing time of the adhesive, and the joint material between the tiles cannot be hit unless the adhesive is hardened after such a long time, which significantly impairs the productivity.

The present invention has been made in view of the above problems in the conventional method for manufacturing a waterproof floor, and an object of the present invention is to solve the above problems and to install tiles for a long time. It is to provide a method for manufacturing a wash floor that does not require it.

[0008]

In order to achieve the above object, in the method for producing a waterproof floor of the present invention, a waterproof floor coated with tiles is manufactured by molding a fiber-reinforced thermosetting resin using a mold. In the method for producing, a silicon-made lattice-shaped die is provided on the die surface, and in each opening of the silicon-made lattice-shaped die,
A tile with a backside recessed part is set so that the backside appears on the front side, and a fiber-reinforced thermosetting resin layer is laminated on the backside of the tile to form a fiber-reinforced thermosetting resin and tile. It is characterized by integrating and.

In the present invention, the material of the tile is not particularly limited, but for example, an inorganic material such as pottery, porcelain, natural or synthetic stone material, or
Hard vinyl chloride resin, polyethylene, polypropylene,
A synthetic resin such as FRP or rubber is preferably used.

In the present invention, the silicone is not particularly limited as long as it is rubber-like or resin-like, but silicone rubber having elasticity and releasability is preferably used.

[0011]

In the method of manufacturing a waterproof floor according to the present invention, a silicone lattice-shaped die is provided on the die surface, and each opening of the silicone lattice-shaped die is provided with a deep recess on the back surface. Since the tile is set so that its back surface appears on the front surface, and the fiber-reinforced thermosetting resin layer is laminated on the back surface of the tile, the fiber-reinforced thermosetting resin and the tile are integrated. Since the tiles are attached at the same time as the waterproof floor is formed and no adhesive is required, it does not take a long time to attach the tiles.

Further, since the lattice type made of silicone is used, the tile can be easily set by setting the tile in the opening, and the lattice type made of silicone is highly elastic, so that the size of the tile can be adjusted. Even if there is some variation, the variation in tile size is absorbed. Further, since the lattice-shaped mold made of silicone is excellent in releasability, the lattice-shaped mold made of silicon can be easily released after molding.
