(Field of Industrial Application) The present invention relates to an inorganic base material for the interior and exterior of buildings, and more specifically to the improvement of an inorganic base material for construction that is to be used as a base for tiles and other decorative finishes. (Prior Art) Asbestos-calcium silicate noncombustible materials have been widely used as base materials for the interior and exterior of bathrooms, kitchens, and other architectural structures. Such noncombustible materials are affixed to the walls, ceilings, or floors of the above-mentioned building structures, and the surfaces are tiled or painted to provide a finish that is noncombustible, tough, and water resistant. Because of the presence of asbestos, its uses were wide-ranging, but recently, the issue of asbestos pollution has come to the fore, and there has been a call for so-called non-asbestos. In addition, the asbestos-calcium silicate material mentioned above has a water absorption rate of 40 to 50.
%, and when molded as a base material, it is heat-pressed into multiple layers, so repeated water absorption and drying during long-term use can cause problems such as delamination between layers and deformation of the material. Ta. (Problems that the invention attempts to solve) In response to the above-mentioned demand for non-asbestos,
New materials that combine cement (calcium silicate) with glass fibers, pulp, or organic fibers have been developed and are now commercially available, but they have yet to surpass the asbestos-based materials mentioned above in terms of strength, water resistance, and cost. I wasn't there. In addition, the present applicant has filed a patent application No. 49-
The non-combustible inorganic decorative board proposed in No. 093583 (sold by the applicant as "Caverian" and well received) is non-asbestos, water resistant and
Although this architectural board has extremely high strength, it is itself a decorative board, so it is not suitable for use as a base material as described above. However, since the surface of the decorative board is covered with patterned paper impregnated with a thermosetting resin and a surface layer member made of the same resin, the adhesion between these and tile adhesives and paints is poor. It had no suitability as a building material. Furthermore, recently, in order to improve the working environment of factories and other places with high heat and humidity, the above-mentioned non-combustible inorganic decorative laminates have been used as interior materials. Since the mold resin is exposed, the surface has the disadvantage of turning black due to high heat, and even if it is painted with an inorganic paint with excellent heat resistance to prevent this, it will eventually peel off due to the above reasons. It can withstand such uses without being able to fulfill its purpose due to aging.
Moreover, the development of non-asbestos building materials was also desired. The present invention was obtained as a result of repeated research based on the technology accumulated by the applicant, and is a highly useful novel construction material that is non-asbestos and can replace asbestos-based base materials. The purpose is to provide an inorganic base material. (Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained based on the attached embodiment drawings. FIG. 1 is a partial longitudinal sectional view showing an example of the inorganic base material for construction of the present invention;
FIG. 2 is a similar diagram of another embodiment. That is, the inorganic base material for construction of the present invention includes an inorganic base material layer 1 containing an inorganic aggregate and a thermosetting resin binder, a reinforcing layer in which a paper reinforcing base material and a thermosetting resin are impregnated and integrated. 2 and a thin surface layer 3 containing an inorganic aggregate and a thermosetting resin binder are integrally molded in this order under heat and pressure. The inorganic base material layer 1 of the present invention is mixed with main aggregate, auxiliary aggregate, reinforcing material, thermosetting resin binder, etc., and is laminated in a sandwich-like structure with constituent materials of other layers to be described later, and is hot-pressed into a plate shape. These materials are formed by molding and hardening, but the details of each of these materials are as follows: Main aggregate: Solid powder of aluminum hydroxide (A1 2 O 3 3H 2 O) is used as the main aggregate. 5 to 97% of the total amount (weight, same below),
Preferably, it is blended in an amount of 50 to 70%. This aluminum hydroxide does not change thermally at a molding temperature of 200°C or lower, but when the ambient temperature reaches 300 to 550°C, it releases crystallized water and suppresses combustion, and at the same time becomes A1 2 O 3 as a heat-resistant material, so it cannot be used in molded products. provides non-flammability. Auxiliary aggregate: An inorganic filler is used as an auxiliary aggregate together with the main aggregate. Such auxiliary aggregates are used for purposes such as improving the mechanical strength of molded products, reducing costs by increasing their weight, and imparting flame retardancy, and include silica sand, calcite powder, calcium silicate, zeolite, kaolin, and bentonite. ,
Acidic clay etc. are used. Reinforcing agents: Inorganic fibers (glass fibers, ceramic fibers), metal fibers (iron fibers, aluminum fibers, whiskers, etc.), natural fibers (cotton, linen cotton, etc.), synthetic resins to further increase the mechanical strength of molded products. Fibers (vinylon, nylon, tetron, etc.)
of fiber is added. Resin binder: The binder used is a flame-retardant thermosetting synthetic resin that imparts molding fluidity to each of the above materials and can be cured by heat and pressure. Formalin condensates and derivatives thereof, furan-formalin condensates and derivatives thereof, polydiphenyl oxide resins and derivatives thereof, etc. are used, and the amount used is 3 to 12% of the total constituent materials of the base layer 1. Further, the reinforcing layer 2 imparts tough mechanical strength to the molded product, and is made by impregnating and supporting a thermosetting resin similar to the above into a paper reinforcing base material such as kraft paper or Japanese paper. Furthermore, the surface layer 3 is mainly composed of the same main aggregate and resin binder as the constituent materials of the inorganic base layer 1, and the blending ratio of both is substantially the same as that of the inorganic base layer 1. In the inorganic base material for construction of the present invention, the above material formulated for the inorganic base layer 1 is placed on a press plate of a hot press, and the above sheet for the reinforcing layer 2 is placed on top of it. It is obtained by placing the materials blended and prepared for the surface layer 3 on the surface layer 3 and hot-pressing them all at once. At this time, it is also possible to use an embossing press mold as a press plate on the surface layer 3 side to apply an embossing pattern such as a tile pattern on the surface layer 3 as appropriate. In addition, the order in which the materials are placed on the press plate may be reversed to the above, and it is also excluded that the reinforcing layer 2 and the surface layer 3 are formed on both sides of the inorganic base layer 1 (see Figure 2). It's not something you do. Furthermore, not only plate-shaped products but also accessories such as inner and outer parts can be easily molded by changing the mold. (Function) In the inorganic base material for construction having the above structure, the inorganic base material layer 1 imparts nonflammability, and the synergistic effect of the base material layer 1 and the reinforcing layer 2 makes the entire base material extremely It is considered strong. The surface of this reinforcing layer 2 is a surface layer 3 made of inorganic aggregate and a resin binder.
Since the surface is covered with , this surface has good adhesion to adhesives and various paints. Therefore, the base material of the present invention can be used as a wall (including floor and ceiling) material of a building structure, and this surface can be tiled with an appropriate adhesive, or various organic or
Even if the finish is painted with inorganic paint,
No peeling phenomenon of these finishing layers over time is observed. Therefore, if you tile it, you can create a beautiful non-combustible decorative board, if you paint it with an inexpensive organic paint, you can create a general-purpose decorative board, and if you paint it with an inorganic paint, you can create a heat-resistant and non-combustible decorative board.
Non-combustible makeup with excellent fire resistance and water resistance can be created. Moreover, since each of the above constituent layers does not contain asbestos, there is no concern that so-called asbestos pollution will occur, and it can fully meet the current trend of non-asbestos. In addition, the base material of the present invention has a reinforcing layer 2 in which paper and thermosetting resin are integrally impregnated between the base layer 1 and the surface layer 3.
is interposed, so the water absorption rate is extremely low (1~
2%), does not cause deformation or delamination, and is suitable for use as exterior wall materials and interior materials for bathrooms, kitchens, etc. (Example) Examples of the present invention will be described below. 1st
Table and Table 2 show inorganic base layer 1 and surface layer 3, respectively.
This shows the blending ratio of the base material.

[Table] In addition, a paper reinforcing base material made of kraft paper impregnated with melamine resin and dried was used as a sheet for the reinforcing layer 2, and these were layered in a press to yield 100Kg/cm 2 and 150
Hot pressed at ℃ for 5 minutes. By hot pressing, an extremely robust plate-like substrate was obtained, which was strongly integrated by the mutual bonding of the thermosetting resins in each layer. A tile was adhered to this surface via a synthetic resin adhesive, and a synthetic resin paint was applied to the surface to perform an adhesion test, and the adhesion was good in all cases. We also conducted an adhesion test under accelerated conditions of high temperature and humidity, but no abnormalities were observed in this case either. Figures 1 and 2 show modified forms of the base material obtained above, and Figure 1 shows one in which a reinforcing layer 2 and a surface layer 3 are laminated and integrated on one side of an inorganic base material layer 1. On the other hand, FIG. 2 shows a reinforcing layer 2 and a surface layer 3 formed on both sides of the inorganic base layer 1. The former is applied when it is necessary to finish one side, such as a wall, and the latter is applied when it is necessary to finish both sides, such as a partition, and both are preferably employed. Note that the embodiment is not limited to the above embodiment, and for example, in the case of FIG. 1, on the back surface of the base material layer 1,
In the case shown in the figure, it is also possible to integrate a glass net or the like between the base material layer 1 and the reinforcing layer 2, respectively, to further increase the mechanical strength. (Effects of the invention) As mentioned above, the inorganic base material for construction of the invention has the following properties:
Since its constituent materials do not contain any asbestos, it can fully meet the requirements for non-asbestos.
In addition, the inorganic base material layer, which is the main part of the base material, is itself made of inorganic aggregates bonded together with thermosetting resin, so it has considerable mechanical strength and can be reinforced with a reinforcing layer. Because of this, it is said to be extremely strong overall. Furthermore, since its surface is covered with a surface layer that combines inorganic aggregate and thermosetting binder, it has good adhesion to adhesives and various paints, allowing for freedom in tiling and paint finishing. It will be done. Furthermore, since each layer contains a thermosetting resin, they are compatible with each other and maintain strong adhesion between the layers. From this, it can be said that the inorganic base material for construction of the present invention is extremely useful, exceeding the conventional asbestos-calcium silicate construction materials.
