Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used when a board such as a wall material (decorative board), a ceiling board, or a floor board is attached to a wall surface, a ceiling, or a floor surface of a building by interposing them as a sticking material. Related to the sticking material of the board, which has especially heat insulation and adhesiveness, does not cause dew condensation, and further,
The present invention relates to a board sticking material that is also useful for reusing waste materials such as industrial waste.

[0002]

2. Description of the Related Art When constructing a building, a construction method is usually adopted in which a sticking material is attached to a wall surface, a ceiling, or a floor surface, and a board such as a wall material (decorative board), a ceiling board, or a floor board is attached to the sticking material. Has been done. This adhesive material is spray-painted on almost the entire surface of the wall, ceiling or floor, and is also used as a heat insulating material, or it is partially attached to the wall, ceiling or floor as dumpling putty and used as a bond. Has been done.

Conventionally, urethane foam resin, polystyrene foam, glass wool, etc. have been used as the above-mentioned heat insulating material, and as the dumpling-like putty, cement and gypsum as a main component, and a mixture of these in a putty form has been used. There is.

[0004]

[Problems to be Solved by the Invention] However, as the former heat insulating material, no consideration is given to the use of waste material,
In addition, the latter dumpling-like putty contains 90% by volume or more of cement or gypsum, and therefore has high water absorbency and causes dew condensation, which inevitably causes mold. Further, since it has no heat insulating property, it cannot be used as a heat insulating material.

Therefore, the object of the present invention is not only useful for the recycling of waste materials such as industrial waste, but also because it has a low water absorption, it does not cause dew condensation, and it is also excellent in heat insulation and adhesiveness. The purpose of the present invention is to provide a board sticking material which is used not only as a heat insulating material but also as a dumpling putty and which has improved the drawbacks existing in the prior art.

[0006]

In order to achieve the above-mentioned object, according to the present invention, the above-mentioned wall, ceiling or floor is mainly used when a board is attached to the wall, ceiling or floor of a building. A sticking material for a board, which is used by being interposed between a surface and a board, which is a crushed foam waste material made of styrofoam and / or urethane foam, and a solidifying material made of gypsum and / or cement, and a synthetic material. It is made of a kneaded material containing a resin adhesive as a main component, and the compounding amount of the solidifying material is 50 parts by volume or less relative to 100 parts by volume of the foaming waste material.

[0007]

The present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a partial cross-sectional view of an example in which the adhesive material according to the present invention is used as a heat insulating material, and FIG. 2 is a partial cross-sectional view of an example in which it is used as dumpling-like putty.

First, in detail from the use example as a heat insulating material in FIG. 1, 1 is a concrete wall of a building,
The kneaded material according to the present invention is applied onto the wall surface 2, the ceiling 3 and the floor surface 4 by spray coating to form the heat insulating material 5. Then, a board 6 such as a wall material (decorative board), a ceiling board, or a floor board is attached and adhered and fixed onto the heat insulating material 5, and the wall 6, the ceiling 3, the floor surface 4, and the board 6 are respectively separated. The heat insulating material 5 is interposed.

Next, an example of use as a dumpling-like putty in FIG. 2 will be described. 1 is a concrete wall of a building as in FIG. 1, and the kneaded material according to the present invention is dumpled on this wall surface 2 with a plastering iron. Then, a plurality of dumpling putties 7 are formed. After that, the board 6 as a wall material is stuck on the dumpling-like putty 7 and fixed by adhesion, and the dumpling-like putty 7 is interposed between the wall surface 2 and the board 6.

The above-mentioned kneaded material is a sticking material according to the present invention, which is a crushed foam waste material made of expanded polystyrene and / or urethane foam, a solid material made of gypsum and / or cement, and a synthetic resin adhesive. It is formed by mixing the agent and a main component, and adding methyl cellulose or a derivative thereof, if necessary, to this, and further adding a desired amount of water, and sufficiently stirring.

In the above kneaded product, the amount of the solidified material mixed with the foaming waste material is particularly important. That is, the compounding amount of the solidifying material is 50 parts by volume or less, preferably 10 to 40 parts by volume, more preferably 20 to 40 parts by volume, still more preferably 30 to 40 parts by volume with respect to 100 parts by volume of the foaming waste material. is there. If the blending amount exceeds 50 parts by volume, the water absorption becomes large and dew condensation occurs. The compounding amounts of the synthetic resin adhesive and the cellulose derivative are arbitrary and appropriate amounts.

The above-mentioned waste foam material is industrial waste such as styrofoam, urethane foam, etc.
It is crushed to a diameter of about 4 mm. Further, the above-mentioned solidifying material is one kind of gypsum, cement (white cement, etc.), or a combination of plural kinds thereof. Also,
The above-mentioned synthetic resin adhesives are thermosetting resin adhesives such as polyurethane resin, epoxy resin, polysulfide epoxy resin, etc., thermoplastic resin adhesives such as acrylic resin, vinyl acetate resin, vinyl acetate copolymer resin, ethylene vinyl acetate resin, etc. , Styrene / butadiene latex, acrylonitrile / butadiene latex, acrylate latex, vinyl chloride latex, and other synthetic rubber adhesives. Furthermore, examples of the cellulose derivative include methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose and the like.

[0013]

Since the sticking material of the present invention having the above-mentioned constitution uses the waste material such as industrial waste as a material, it is not only useful for the reuse of the waste material, but also this waste material is the main component and the cement, gypsum, etc. Since the amount of the solidifying material is as small as 50% by volume or less with respect to 100 parts by volume of the foaming waste material, the water absorption is small, dew condensation does not occur, and it has heat insulating property. Furthermore, since it contains a synthetic resin adhesive, it is adhesive Therefore, it is widely used as a heat insulating material, as a dumpling putty (bond), and as a filler for the space between the concrete and the sash. It should be noted that the addition of the cellulose derivative enhances the water retention property and improves workability.

As shown in FIG. 2, a plurality of the kneaded materials thus obtained are attached to the wall surface 2 of the concrete wall 1 in the shape of a dumpling using a plastering iron to form a dumpling-like putty 7 (bond). Stick the wall material (board) 6 on top and fix it with adhesive,
The dumpling putty 7 was used by interposing it between the wall surface 2 and the board 6.

Since the above-mentioned dumpling putty 7 according to the present invention uses industrial waste of expanded polystyrene resin as a part of the material, it is useful for utilization of the waste material and its water absorption is small and does not cause dew condensation. Generation is prevented, and besides, it is excellent in heat insulation, self-adhesiveness, and easy to manufacture.

[0022]

As described above, the board-adhering material according to the present invention is not only useful for recycling waste materials such as industrial waste, but also does not cause dew condensation due to its small water absorption, and also has heat insulating and adhesive properties. Therefore, the invention is not only used as a heat insulating material but also used as a dumpling putty, which is a practically useful invention.
