DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall material for a plaster wall formed by plastering and a plaster wall formed by the wall material, which is excellent in fire resistance and heat resistance, and removes harmful substances and dehumidifies. The present invention relates to a wall material for a painted wall having various functions such as a deodorizing effect and a painted wall using the wall material.

[0002] In the present specification, the term "painted wall" refers to a case where a wall formed by a method other than plastering is used as a base and a wall material is applied and dried on the surface of the base wall. , And a part of the wall.

[0003]

With the spread of reinforced concrete buildings in recent years, as the airtightness and airtightness of offices and houses have been improved, dew condensation caused by a difference in temperature between the inside and outside of the building, and this dew condensation, And various problems such as generation of mold.

[0004] Further, an organic solvent contained in an adhesive used for bonding wallpaper or the like, a paint used for wall decoration, a varnish used for furniture arranged in a room, and the like,
Other chemical substances have caused problems such as contamination of indoor air.

[0005] Among these problems, a plate-like body formed by bonding charcoal with an adhesive or the like so as not to lose air permeability is applied to a gypsum board, a plate material, or the like for the purpose of adjusting indoor humidity. An inner wall material for attaching a wall material formed by wearing to the inside of an outer wall material such as a mortar or the like (Japanese Patent Application Laid-Open No. 6-49916), or a rectangular frame is divided into a number of chambers in a honeycomb shape. A wall material or the like in which activated carbon and charcoal are filled and at least one surface of a frame is covered with a permeable sheet is disclosed (JP-A-6-240770).

[0006]

In the conventional wall material constructed as described above, the active adsorbing action of the charcoal or the activated carbon causes a substance which generates moisture or odor in the indoor air. The effect of adjusting humidity, removing odor, and absorbing harmful substances etc. is produced.

However, Japanese Patent Laid-Open Publication No.
In the interior material described in Japanese Patent Publication No. 6, charcoal having an active adsorption effect is embedded and bonded to an adhesive, so that the area exposed to the surface of the charcoal is small, and the active adsorption effect is sufficiently improved. It cannot be demonstrated.

Further, when a wall material is formed by using a resin material such as an adhesive, the wall material thus formed is inferior in heat resistance and fire resistance and burns out in the event of a fire or the like. For example, there is a problem that harmful gas may be generated in the human body.

Further, charcoal is solidified with an adhesive, formed into a plate shape, and the plate member containing charcoal formed in the plate shape is stuck to a gypsum board or a plywood plate by molding using a mold, and forming each layer. Since a work such as polymerization is required, it must be manufactured at a factory or the like having a mold. On the other hand, in order to use the interior material carried to a building work site such as a house as an inner wall of each room, it is necessary to cut the interior material into a shape adapted to the wall surface of each room.

Further, in the building panel disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 6-240770, since the inside of the frame is partitioned into small honeycomb-shaped chambers, the outer shape of the panel is determined by the shape of the frame. The degree of freedom of the shape change due to the processing at the construction site is smaller than that disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 6-49916.

[0011] Further, when a paper material or the like is used as the permeable sheet, there is no heat resistance and fire resistance, and when a synthetic resin or the like is used as a material, harmful gas or the like is generated during combustion. There is also a risk.

This is the amount derived as a result of the experiment.

[Zeolite] The zeolite used for the wall material for a painted wall according to the present invention has a very porous structure, a large number of voids therein, and a drying agent, a deodorant, a contaminated air due to its excellent adsorbing action. It is used as an adsorbent for purifying water, decomposing various harmful gases, and adsorbing positive ions.

The zeolite used in the present invention can be either natural zeolite or man-made zeolite, and the type of zeolite is limited as long as it can exert a suitable adsorption effect. Not done.

As an example, the component composition of the zeolite (from Nishiaizu and Nozawa) used in the present embodiment is as shown in the following table.

[0027]

[Table 1] Component composition of zeolite The above zeolite is rolled and crushed by, for example, a roller mill or the like to form particles of 100 to 50 mesh, and a zeolite powder to be added to the wall material for a painted wall of the present invention is obtained.

[Negative ion generating substance] The wall material for a painted wall of the present invention is more preferably added with a negative ion generating substance.

In this embodiment, tourmaline is used as the anion generating substance, and the anion generated by the tourmaline is released into the room provided with the painted wall made of the wall material of the present invention. It is configured.

When only the effects obtained by the above-described adsorption action of zeolite are added to the wall material of the present invention, such as the adsorption of harmful substances, the removal of offensive odors, the adjustment of humidity, and the adsorption of positive ions, this minus sign is used. The addition of an ion-generating substance is not always necessary, and as the anion-generating substance, for example, barley stone,
Other known negative ion-generating substances such as bamboo charcoal, tied rock, and Ioishi can be mixed.

In the case of carbon such as bamboo charcoal, the amount of released negative ions decreases with time. However, tourmaline, a natural mineral, generates negative ions in response to solar energy. Unlike the case where carbon such as bamboo charcoal is mixed, the amount of released negative ions does not decrease with time. Therefore, it is suitable in terms of the continuity of the negative ion releasing effect.

By adding a negative ion generating substance such as tourmaline in this manner, negative ions are always released into the room surrounded by the painted wall. This negative ion is contained in a large amount in the air where the air is said to be clean and good for the body, for example, around plateaus, forests, and waterholes. By absorbing into the body from breathing and skin, it obtains sedimentary effects known as the effects of negative ions, such as analgesia, good sleep, antitussive, antiperspirant, increased appetite, decreased blood pressure, exhilaration, and fatigue prevention be able to. Therefore, by living in a space surrounded by the painted wall made of the wall material of the present invention, it is possible to obtain a refreshing feeling and the like as if a forest bath were performed while staying indoors.

In addition, the negative ions generated by the negative ion generating substance such as tourmaline combine with active oxygen which is considered to be harmful to the human body and render it harmless.

In the present embodiment, this tourmaline is pulverized to 50 mesh and mixed as tourmaline particles.

[Binder] Lime and calcium are added as a binder for binding the above zeolite powder and tourmaline powder. Since the binder has air permeability even after being formed as a painted wall, the zeolite bound by the binder is not affected even when all or a part of the zeolite is embedded in the binder. Does not lose adsorption performance.

Further, the binder made of lime and calcium is excellent in heat resistance and fire resistance, and there is no danger of generating toxic gas or the like when burned, unlike the binder made of a synthetic resin material or the like.

In this embodiment, both lime and calcium are used, each having a particle size crushed to 150 mesh.

[Manufacture of coated wall] The coated wall material composed of zeolite powder, tourmaline powder, lime and calcium is about 50% by weight to 100% by weight of the coated wall material.
% Of water is added and kneaded to form a paste-like kneading material having appropriate plasticity.

Then, the kneading material is applied on a wall base such as a scratch base, a fine base, a lath base, a lath board base, etc. to form a coated wall. To form a painted wall.

After the application, the binder is dried by contacting with air, and the lime in the binder becomes carbonated lime to form a hard coating, and a suitable strength as a wall material is obtained. Since it is aqueous, it does not hinder the adsorption of zeolite.

Since the wall material thus obtained is made by mixing zeolite powder into the wall material, the adsorption effect exerted by the porosity of the zeolite allows the wall material in the indoor atmosphere facing the wall material to be formed. Adsorbs harmful substances, bad odors, moisture and positive ions.

When a negative ion-generating substance such as tourmaline is contained, a large amount of negative ions are released into the room facing the painted wall, and a person in the room surrounded by the painted wall can In addition to providing a sedative effect, it exerts effects such as binding to active oxygen and rendering it harmless.
