Description

  The present invention relates to a dry plaster finish panel for architecture in which a coating material made of natural material-derived aggregate, binder or the like is applied to the surface.

  Stucco, diatomaceous earth, Juraku soil, etc. are used as wall finishing materials for buildings. These are mixed with hydraulic binders such as slaked lime, gypsum, cement, resin, etc., added with water to form a slurry and applied to the wall (left plastering), and the hydraulic binder is cured by natural drying to finish the wall. As fixed.

Wall finishing materials such as plaster, diatomaceous earth, and Juraku soil are naturally derived materials such as soil and plant fibers, and also have non-combustibility and humidity control performance. They are friendly to the environment and human body, and avoid sick house syndrome. Demand is growing as a building material.
On the other hand, it is required to use a material that is naturally derived and friendly to the environment and the human body for the binder used in these.
The hydraulic binders such as slaked lime, gypsum, and cement are highly alkaline with pH 12-13, and structures produced using these are also strongly alkaline with pH 12-13. For this reason, it has been pointed out that components such as calcium hydroxide are eluted by corrosion due to acid, which adversely affects the human body and the natural environment.
Resin-based hydraulic binders are also pointed out to cause formaldehyde and cause sick house syndrome.
Therefore, as a substitute for the above strong alkaline hydraulic binder, a weak alkaline hydraulic binder using a magnesium inorganic salt derived from seawater as a raw material has been proposed (Patent Documents 1 and 2). This hydraulic binder has been confirmed to have a curing performance comparable to that of the conventional hydraulic binder described above, in addition to containing a weakly alkaline component having a pH of about 10 and no components that adversely affect the human body or the natural environment.

Not only is the wall surface of the fixed building finished with plaster, diatomaceous earth, or turquoise (wet method), but it is also dry-fixed by applying these to the surface of a plate-shaped member of a specified size. There was a demand to distribute as a plastering panel (decoration panel).
However, due to the following problems, it was not realistic to distribute dry plastering panels as products.
(1) In the process of drying finishing materials applied to substrates such as plywood, calcium silicate plates, and gypsum plates, moisture penetrates into the substrate and causes warping of the substrate. (2) Transfer, general entry and exit, The impact of the distribution process such as exhibition and construction may cause cracks on the surface or cause peeling. The problem (2) can be solved by using a high-strength resinous hydraulic binder. There is, however, no response to the desire to distribute dry plastering panels using natural materials.
In view of such problems, the present invention is intended to provide a dry plastering panel that uses only natural materials for both the aggregate and the binder and has the strength to withstand distribution.

The present inventor first proposed a weakly alkaline and natural hydraulic binder made of seawater-derived magnesium inorganic salt as a raw material instead of strong alkaline hydraulic binders such as slaked lime, gypsum and cement. Pay attention. After applying this hydraulic binder (product name: Magene (registered trademark)) to a substrate such as plywood, drying and fixing, and applying an impact to the extent that it occurs in the distribution process, cracks in the surface finish material No peeling occurred.
However, the problem that the moisture of the finishing material penetrates into the substrate and causes the substrate to warp has not been improved.

The inventor further searched for an alternative substrate to prevent the penetration of the moisture of the finishing material into the substrate such as plywood, and as a result, a building material panel having a thin aluminum layer near the inner surface of the substrate is commercially available. (Patent Document 3), and came up with the idea of using this as a substrate.
The building material panel (product name: DAILIGHT (registered trademark)) was coated with a finishing material mixed with plaster, diatomaceous earth, Juraku soil, etc. and a hydraulic binder (product name: MAGEN (registered trademark)), and dried and fixed. In the dry plastering panel obtained by this manufacturing method, the aluminum thin layer hinders the penetration of moisture into the substrate, so that the substrate does not warp after drying.

2. Deodorization Test A method for testing the deodorizing performance of the surface finish used for the dry plastering panel of the present invention will be described.
The following is a method for performing a deodorization test on formaldehyde, ammonia, and hydrogen sulfide as an example of a test method.
In accordance with this example, the following two samples are prepared.
Sample (1) A slurry obtained by applying 20 g of a hydraulic composition slurry containing a hydraulic binder and coffee husk to the surface of pebbles having an average diameter of about 10 cm, followed by drying and curing.
Sample (2) A slurry obtained by applying 20 g of a hydraulic composition slurry containing a hydraulic binder, coffee husk, and wood chips to the surface of pebbles having an average diameter of about 10 cm, followed by drying and curing.

The procedure of the deodorization test is as follows.
<Formaldehyde>
As the detection tube, formaldehyde 91M, 91L (manufactured by Gastec Co., Ltd.) is used.
A sample gas is obtained by evaporating an appropriate amount of formaldehyde and diluting it with air and adjusting the concentration to about 120 ppm while measuring the concentration with a detector tube.
Prepare an analytic barrier bag containing sample (1), an analytic barrier bag containing sample (2), and an analytic barrier bag containing nothing.
A sample gas is injected into each analytic barrier bag, and the concentration of vaporized formaldehyde in the atmosphere when a predetermined time has elapsed is measured with a detector tube.

The measurement results are shown in FIG.
In both sample (1) and sample (2), vaporized formaldehyde was gradually adsorbed, and almost all of the sample was adsorbed after 20 hours.
Therefore, both sample (1) and sample (2) exhibit a remarkable deodorizing effect on vaporized formaldehyde, and it can be seen that sample (2) has a higher deodorizing effect than sample (1).

<Ammonia>
As the detection tube, ammonia 3L, 3La (manufactured by Gastec Co., Ltd.) is used.
A sample gas is obtained by evaporating an appropriate amount of ammonia water and diluting it with air and adjusting the concentration to about 120 ppm while measuring the concentration with a detector tube.
Prepare an analytic barrier bag containing sample (1), an analytic barrier bag containing sample (2), and an analytic barrier bag containing nothing.
A sample gas is injected into each analytic barrier bag, and the concentration of vaporized ammonia in the atmosphere when a predetermined time elapses is measured with a detector tube.

The measurement results are shown in FIG.
In both sample (1) and sample (2), it is considered that vaporized ammonia was gradually adsorbed and about 90% was adsorbed after 20 hours.
Therefore, both sample (1) and sample (2) exhibit a remarkable deodorizing effect on vaporized formaldehyde, and it can be seen that sample (1) and sample (2) have the same degree of deodorizing effect.

<Hydrogen sulfide>
As the detection tube, hydrogen sulfide 4L, 4LK, 4LT (manufactured by Gastec Co., Ltd.) is used.
Dilute hydrochloric acid is added to an appropriate amount of sodium sulfide to generate hydrogen sulfide gas, diluted with dry air, and adjusted to about 120 ppm while measuring the concentration with a detector tube to obtain a sample gas.
Prepare an analytic barrier bag containing sample (1), an analytic barrier bag containing sample (2), and an analytic barrier bag containing nothing.
A sample gas is injected into each analytic barrier bag, and the concentration of vaporized hydrogen sulfide in the atmosphere when a predetermined time elapses is measured with a detector tube.

The measurement results are shown in FIG.
In both sample (1) and sample (2), vaporized hydrogen sulfide is gradually adsorbed, and it is considered that almost the entire amount has been adsorbed after 6 to 20 hours.
Therefore, both sample (1) and sample (2) exhibit a remarkable deodorizing effect on vaporized hydrogen sulfide, and it can be seen that sample (2) has a higher deodorizing effect than sample (1).

  In the same manner, the samples 1 to 8 were subjected to a deodorization test. As a result, in all samples, (1) formaldehyde, (2) ammonia, and (3) hydrogen sulfide were significant compared to the case without the sample. It was confirmed that a high deodorizing effect was exhibited (see FIG. 2).

3. Strength test In order to test the strength of the surface finish used in the dry plastering panel of the present invention, three samples (molded bodies) were separately prepared. The composition of the material of each sample is shown in FIG.
Sample No. 11 uses only the hydraulic binder “Magene Standard Type (Magene S)” as the raw material, and has the highest compressive strength among the three samples.
Sample No. 12 uses the same weight parts of hydraulic binder “Mugen Standard Type (Mugen S)”, Asakura stone powder and rice husk as raw materials. Compressive strength is inferior to sample number 11 by containing a odor material.
Sample No. 13 is based on the hydraulic binder “Magene Standard Type (Magne S)” and twice the weight part of the rice husk. The deodorant is twice as much as the hydraulic binder. By containing, compressive strength is inferior to sample number 12.

  However, the compressive strength of sample number 11 is about 2.5 times that of general concrete, the compressive strength of sample number 12 is almost the same as that of general concrete, and the compressive strength of sample number 13 is general concrete. It is about 1/2 of this. Therefore, a molded product having a certain strength can be manufactured using a raw material in which about twice as much aggregate (and deodorant material) is mixed with the hydraulic binder. It can also be used as a coating material.

  As mentioned above, although the concrete embodiment was shown and demonstrated about the dry-type plastering panel of this invention, this invention is not limited to these. If it is an expert, within the range which does not deviate from the summary of this invention, regarding the selection in the said each embodiment, a hydraulic binder, an aggregate, a deodorizing material, an additive, etc., its compounding ratio, mixing, and a molding method Various changes and improvements can be added.

  The present invention can be used industrially as a dry plastering panel and a manufacturing method thereof.
