Description

[0001]
[Industrial applications]
The present invention relates to an improvement in a method for manufacturing a tiled panel using a highly fluid adhesive.
[0002]
[Prior art]
Conventionally, as a method for manufacturing a tile-attached panel, there is a method using a highly fluid adhesive disclosed in Japanese Patent Application Laid-Open No. 6-307055. In this method, as shown in FIG. 4, as shown in FIG. 4A, a highly fluid adhesive 2 is applied to a panel substrate 1 and a plurality of tiles 3 are joined on the adhesive 2 at predetermined intervals. The adhesive 4 overflowing the joints 4 is naturally smoothened by its high fluidity, and the adhesive 2 is cured and tiled as shown in FIG. This is for manufacturing the wearing panel 5.
[0003]
[Problems to be solved by the invention]
The adhesive 2 is set to have a slow curing time because it is necessary for the adhesive 2 to have a flow time in which the material overflowing into the joint portion 4 becomes naturally smooth.
However, the slow curing time of the adhesive 2 increases the curing period from pressing and sticking of the tile 3 to the curing of the adhesive 2, and prevents uncured tile 3 from being displaced during the curing period. The tile sticking panel 5 cannot be carried out from the place where the tile sticking equipment (not shown) is arranged, and the operation efficiency of the tile sticking equipment is reduced, thereby lowering the productivity.
[0004]
Therefore, in order to solve the above-described problems, the present invention provides a method of manufacturing a tile-attached panel that can transport a highly fluid adhesive overflowing in joints even in an uncured state, and an adhesive overflowing in joints. It is an object of the present invention to provide a method for manufacturing a tile-attached panel, which can shorten the period from when it becomes naturally smooth to when it becomes a transportable cured state.
[0009]
[Means for Solving the Problems]
In the method for manufacturing a tile-attached panel according to claim 1 of the present invention, a high-flowable adhesive is applied onto a panel substrate, and a plurality of tiles are provided on the adhesive at predetermined joints. In a method of manufacturing a tile-attached panel by pressing and adhering, and naturally overflowing the adhesive overflowing at the joints by its high fluidity, after the adhesive at the joints is smoothed, the adhesive Is exposed to a curing promoting gas atmosphere to promote the curing of the adhesive.
[0011]
[Action]
According to the first aspect of the present invention, after the adhesive at the joint is smoothed, the curing accelerating gas is used to accelerate the curing of the adhesive to suppress the displacement of the tile. It is possible to shorten the period from the point when the surface becomes smooth to the point where it becomes a hardened state that can be carried out.
[0012]
【Example】
Hereinafter, a method for manufacturing a tile-attached panel according to the present invention (hereinafter, referred to as “the present invention manufacturing method”) will be described based on examples shown in the drawings.
(First embodiment)
1 (A) to 1 (D) show a first embodiment of the manufacturing method of the present invention.
In the first step, as shown in FIG. 1A, a highly fluid adhesive 12 is applied on the panel substrate 11 in an appropriate type of coating device 17 in a layer having a thickness T. The panel substrate 11 is a so-called siding material used for an outer wall surface or the like of a building frame, and its material is, for example, cement, calcium silicate, gypsum, resin, steel, or the like, and is not particularly limited.
[0013]
As the adhesive 12, in addition to an inorganic adhesive such as cement mortar, an organic adhesive such as acrylic emulsion, urethane, epoxy, denatured silicone, or an organic, inorganic and intermediate adhesive such as polymer cement is used. A smooth and high fluidity material is selected. In particular, it is preferable to use an organic adhesive as the adhesive 12 because the efflorescence phenomenon of the adhesive 12 itself does not cause a problem unlike the inorganic adhesive, so that the color unevenness of the joint portion 14 described later can be completely prevented.
[0014]
The second step is to hold the plurality of tiles 13, 13... At predetermined joint intervals 15, 15. is there. Before or after each of the held tiles 13 is adsorbed by the adsorbing device 18, an application agent 16 containing a curing accelerator for accelerating the curing of the adhesive 12 is applied to the back surface 13 a thereof. The curing accelerator contained in the coating agent 16 varies depending on the type of the adhesive 12, but when the adhesive 12 is a cement mortar type, a calcium chloride type is used, and the adhesive 12 is a urethane type or the like. In the case of a modified silicon type, a tin compound, an amine compound, or the like is used.
Subsequently, as shown in FIG. 3C, the suction device 18 descends and places a plurality of tiles 13, 13,... On the adhesive 12 applied in layers with the joints 14 at predetermined intervals.

The application area of the application 16 on the back surface 13a of each tile 13 is adjusted so that the application agent 16 does not mix into the overflowing adhesive 12.
[0015]
In the third step, as shown in FIG. 3D, the adhesive 12 overflowing to each joint portion 14 is naturally smoothened due to its high fluidity, and the adhesive 12 contacting with the coating agent 16 is removed. That is, the tiles 13 are hardened to the extent that they do not shift due to the impact during carrying out described later, and the tiles 13 are temporarily fixed.
[0016]
Although not shown, the fourth step, which is the final step, takes out the tile-attached panel 19 to which the tile 13 is temporarily fixed to the curing place, and completely cures the whole including the adhesive 12 of the joint part 14. That is. Since the tiles 13 are temporarily fixed, even if the adhesive 12 that has overflowed to the joints 14 is in an uncured state, it does not shift during the unloading.
In this embodiment, before the adhesive 12 overflowing into the joint portion 14 is hardened, the adhesive 12 can be carried out from the tile adhering equipment including the suction device 18 to the curing place, so that the operation efficiency of the tile adhering equipment is dramatically improved. To increase the overall productivity.

[0018]
In the second step, as shown in FIG. 2B, a coating agent 16 containing a curing accelerator for accelerating the curing of the adhesive 12 is applied to the tile attachment expected positions 12a on the adhesive 12. Before the adhesive 12 is hardened by the coating agent 16, the suction device 18 holding the plurality of tiles 13, 13... At predetermined joint intervals 15, 15,. As shown in the drawing, after a plurality of tiles 13, 13,... Are pressed and adhered on the adhesive 12 applied in a layer form at predetermined intervals of joints 14, a suction device 18 in a non-sucking state is raised (illustrated). (Omitted). The adhesive 12 overflows into each joint part 14 by pressing and attaching each tile 13. As the curing accelerator contained in the coating agent 16, the same one as in the first embodiment is appropriately selected. The application area of the coating agent 16 is adjusted in advance so that the coating agent 16 does not mix into the overflowing adhesive 12.
[0019]
In the third step, as shown in FIG. 3D, the adhesive 12 overflowing to each joint portion 14 is naturally smoothened due to its high fluidity, and the adhesive 12 contacting with the coating agent 16 is removed. That is, the tiles 13 are hardened to the extent that they do not shift due to the impact during carrying out described later, and the tiles 13 are temporarily fixed.
[0020]
Although not shown in the drawing, the fourth step, which is the final step, takes out the tile-attached panel 29 on which the tile 13 is temporarily fixed to the curing place and places the adhesive 12 Is to completely cure the whole, including In the present embodiment, as in the first embodiment, the operation efficiency of the tile adhering equipment including the suction device 18 and the like can be dramatically increased, and the overall productivity can be improved.
