Abstract

PURPOSE:To produce a panel stuck with tiles with a high adhesive strength, in a production process of the ALC panel. CONSTITUTION:A net which does not change in the quality thereof by autoclave aging is laid on a surface of a semi-plastic body, before the autoclave aging, produced by a normal process, and a slurry forming calcium silicate by the autoclave aging is applied on it and the tiles are stuck on it and then the autoclave aging is performed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an ALC panel having a tile attached to the surface thereof.

[0002]

2. Description of the Related Art Generally, when manufacturing an ALC panel, a fine powder of a siliceous raw material such as silica stone or silica sand and a calcareous raw material such as quick lime or cement is used as a main raw material, and finely powdered aluminum or the like is added to a slurry kneaded with water. Add the foaming agent and pour it into the formwork with the rebar. Then, after being lightened for a predetermined period of time, when it is solidified into a semi-plastic state, the form is removed, the outer surface is cut to a predetermined dimension, and a desired thickness is cut with a steel wire or the like. Then, this semi-plastic material is placed in an autoclave, steam cured at high temperature and high pressure, and the surface and side surfaces are cut if necessary to obtain a product.

When a tile is attached to the ALC panel manufactured as described above, the adhesive is applied after the panel is attached to the frame of the building or after the surface of the panel is sealed at the factory. It is applied and tiles are attached and air dried. However, this method has a problem that not only it is troublesome, but also the construction period is long.

[0004]

SUMMARY OF THE INVENTION The present invention provides a method for manufacturing an ALC panel having tiles attached thereto without any trouble.

[0005]

Means for Solving the Problems The production method of the present invention comprises a fine powder of a siliceous raw material such as silica stone or silica and a fine powder of a calcareous raw material such as quicklime or cement, which is used as a main raw material, and a slurry obtained by kneading with water to obtain aluminum fine powder. A net that does not deteriorate by autoclave curing on the surface of the semi-plasticized body that is cut into a predetermined size by cutting the mold and cutting it to a predetermined size after pouring it into the mold after lightening for a predetermined time and solidifying to a semi-plastic state After laying, the slurry for forming calcium silicate by autoclave curing is applied, and after tiles are stuck, steam curing is carried out by the autoclave. Further, as the above-mentioned slurry, a slurry is used which is a repeating process in which water is added to the cutting scraps generated when the above-mentioned semi-plastic material is cut and kneaded.

[0006]

[Function] By placing a net that does not deteriorate by autoclave curing on the surface of a semi-plastic material, apply a slurry that produces calcium silicate by autoclave curing, apply a tile and then steam-cure to form a slurry. Since the tile-bonded ALC panel having a large adhesive strength reacts with the back surface of the tile, it is possible to reduce the number of steps and the construction period. As the net, aramid fiber, polyarylate fiber, carbon fiber, or the like can be used, and the tile is less likely to be peeled off due to the net interposed between the tile and the panel. In addition, if a slurry is used as a slurry in which the cutting scraps generated when the above-mentioned semi-plastic material is cut is mixed with water and kneaded, the raw material can be effectively used and the cost can be reduced.

[0007]

EXAMPLE An example of the present invention will be described below. To 100 parts by weight of silica powder, 10 parts by weight of quick lime, and 50 parts by weight of Portland cement, 50 parts by weight of water was added and kneaded, and 0.1 parts by weight of aluminum powder was added and poured into a mold. After lightening for a predetermined time, after solidifying into a semi-plastic state, removing the mold and cutting it to a predetermined size, spread an aramid fiber net with a wire diameter of 0.5 mm and a mesh spacing of 5 mm on the surface of the semi-plastic material, and repeat the process. About 5 mm of slurry
After trowel coating, sticking tiles and filling with ordinary joint mortar, put it in the autoclave and set it at 10 atm 180 ° C for 1
It was steam-cured for 0 hours. When the tile peeling test was performed on this tile-bonded ALC panel with a peeling tester, it was 8 k.
peeled off with the ALC panel surface attached at g / cm ² ,
Results comparable to the peel strength of tiles bonded by conventional methods were obtained. It should be noted that instead of the above-mentioned process repeated slurry, the above-mentioned respective raw material powders may be blended in the same proportion or a slightly higher proportion of calcareous raw material, and a slurry obtained by adding an appropriate amount of water and kneading may be used, and the joint mortar is an autoclave. It may be filled after curing.

[0008]

Industrial Applicability The net is laid on the surface of the semi-plastic material, the slurry is applied, the tile is attached, and then the steam curing step is repeatedly applied in the autoclave. The slurry is applied, and the tile is attached and then steam cured. As a result, the slurry is integrated with the panel, reacts with the back surface of the tile, and the net is interposed to further increase the adhesive strength.
Since the C panel can be obtained, the number of steps is less than that of the conventional method, and the construction period can be shortened. In addition, if the slurry is used by repeating the process, the raw materials can be effectively used, and the cost can be reduced.
