DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material for an interior material of a building, particularly to an interior material suitable for use as a surface material such as a wall or a partition.

[0002]

2. Description of the Related Art In general, wall materials and partition materials as building interior materials (hereinafter referred to as wall materials) have not only good appearance as decorative properties but also heat insulation, fire prevention, fire resistance, sound insulation, sound absorption, and the like. In addition to these, in addition to these, in addition to these, performance in terms of health, such as measures against sick houses, is also an important performance condition.

[0003] In traditional Japanese wooden houses, there are clay walls and stucco as wall materials, clay walls are made of clay mixed with sand, straw and other fibers, and plaster is made of slaked lime, glue,
It is made by mixing straw, paper, etc. In addition, in ordinary wooden houses, diatomaceous earth is used as a base material for walls, refractory bricks, and wall finishing materials, and lime or cement is mixed with clay in addition to clay as a self-hardening material for earth walls. ing.

[0004] Recently, however, the use of earth walls and plaster for wall materials has been drastically reduced, and panels have been used for exterior and interior materials.
There are many wall structures in which a heat insulating material, a sound insulating material, a sound absorbing material, and the like are interposed between inner and outer panels. For example, a decorative material such as a wood-grain synthetic resin covering material or a flame-retardant wallpaper is adhered to the interior panel.

[0005]

In the interior of the conventional method using earth wall or plaster as a wall material, the livability is at a satisfactory level, and there is no problem in health. However, it is difficult for such a construction method to secure plasterers and other craftsmen and pass on their skills, and it is considered difficult to continue using them for interior decoration of ordinary houses both now and in the future.

[0006] The interior by the panel-type construction method has advantages in that it is economically advantageous by a mass production method and excellent in appearance by a surface material having excellent decorativeness. However, almost no measures against organic compound hypersensitivity and sick house measures by using chemical substances have been taken, and health problems have been pointed out. In addition, many of the materials are synthetic resins, which wastes petroleum resources as compared with the conventional construction method using minerals and plants as main raw materials, and has a problem in waste disposal.

[0007] The present invention provides a material for an interior material which does not use any chemical substance and is made of only natural materials and which eliminates problems in health and waste disposal.

[0008]

The material for interior materials of the present invention is characterized in that water is added to a mixture containing pulp as a main component and clay, a vegetable bond, and a vegetable fungicide to form a paste. And

The material for the interior material is in the form of a paste,
An interior material is obtained by coating the interior material with a base material. In the present invention, all the materials for interior materials are composed only of natural materials and do not use chemical substances. Therefore, even when used for interior materials in the interior of general houses, special organic compound hypersensitivity can be used. No countermeasures or sick house countermeasures are required, and no health problems occur. In addition, there is no waste of petroleum resources and no problems in waste disposal.

As the pulp, it is desirable to use unbleached powder obtained by extracting cellulose fibers from aquatic plants by mechanical treatment, it is preferable to use white clay as the clay, and as the vegetable bond, it is preferable to use seaweed. It is desirable to use a dry powder, and as the plant fungicide, it is desirable to use a liquid obtained by pulverizing mulberry grass and extracting an extract.

As the water plants, for example, reed plants growing naturally in the northeastern part of China can be suitably used. This reed grass grows in large numbers as a perennial plant of the grass family, and there is no problem in terms of material supply and environmental preservation. As the white clay, for example, clay produced in the Amakusa region of Kumamoto Prefecture can be suitably used. Amakusa clay is a white clay. By dyeing unbleached pulp white, the original color of the colorant can be obtained when coloring with an inorganic colorant. Further, as the seaweed, for example, a golden grass from off Tokachi, Hokkaido can be suitably used. Ginseng boiled into paste form is excellent in adhesiveness.

In addition to the above composition, one or both of inorganic coloring agents such as colored sand, stone powder and shell powder, and powdered coal such as coconut shell powder can be added. There are various kinds of colored sands in the Philippines, China, Inner Mongolia, and the like, and these colored sands can be used. Stone powder and shell powder also have a coloring effect, but stone powder also has the effect that interior material products have a fine surface property, and shell powder can give a glossy surface. Sedimentary rock or metamorphic rock powder is used as the stone powder, heritage abalone shellfish is used as the shell powder,
Shell powder such as giant clams and white-necked clams can be used. Coconut shell charcoal powder has excellent adsorptivity and can deodorize and clean indoor air when interior material products are used indoors.

[0013] The composition of the above composition is 5 to 10 parts by weight of clay and 20 to 20 parts by weight of vegetable bond per 100 parts by weight of pulp.
25 parts by weight, 3 to 5 parts by weight of a plant fungicide, 10 to 40 parts by weight of an inorganic colorant and 5 to 6 parts by weight of powdered coal are added as required. In the case of the above weight ratio, since the specific gravity of the pulp is small, the pulp is about 55 to 65% of the whole in the volume ratio, and becomes the main component as a paste-like interior material.

The particle size of the pulp granules as a main component of the above composition has an average particle size of about 0.5 to 1 mm, from the point that the surface as an interior material product emphasizes paper. preferable. The particle size of the clay or the inorganic colorant is selected so that the surface shape of the interior material product becomes natural.

The interior material of the present invention is obtained by pouring the above-mentioned interior material into a mold and drying it, or by coating the above-mentioned interior material onto a base material. By setting the shape and dimensions of the mold, a panel-shaped or block-shaped interior material having appropriate dimensions can be obtained. When the base material is coated, the material and surface properties of the base material are not particularly limited. For example, a gypsum board can be used as a base material for an interior material in a place where fire resistance is required.

[Example 1] Each raw material was mixed and stirred, and allowed to stand for 2 days. Then, 300 cc of a bond was further added and stirred to obtain a paste-like coating material for an interior material. The following compounding ratio is a ratio to the coating amount per 1 m ² of the area of the wall material. Pulp: Unbleached pulp powder of Chinese reed grass 200g Clay: Amakusa white clay 100g Colorant: Inner Mongolian colored sand 500g Anti-mildew agent: Dokudami grass extract 80cc Bond: Boiled glutinous grass paste 300cc Water : 8000cc

Example 2 Raw materials were mixed at the following ratios and stirred to obtain a paste-like interior material, and after standing for 2 days, a mold having an inner dimension of 200 mm long × 400 mm wide × 6 mm thick was used. It was poured into a frame, dried naturally, and then released to produce an interior panel. Pulp: unbleached pulp powder of Chinese reed grass 100 g Clay: white clay from Amakusa 100 g Coloring agent: colored sand from Philippines 50 g coal: coconut shell charcoal powder 12 g stone powder: metamorphic rock powder 50 g shell powder: Hiogi shell Powder 20g Antifungal agent: Dokudami grass extract 40cc Bond: Ginseng boiled paste 70cc Water: 400cc

In both the case of the coating material for the interior material of the first embodiment and the case of the interior panel of the second embodiment, all the raw materials are composed of only natural materials and no chemical substances are used.
Even when the coating material of Example 1 is applied as a surface material of the interior wall material of a general house, or when the panel of Example 2 is used as a wall material, no harmful substances are released, and health is not affected. No problems occur. Further, since pulp is a main component, the humidity control function is large, and there is an effect of preventing dew condensation.

In both the case of the coating material for the interior material of Example 1 and the case of the interior panel of Example 2, since white clay and colored sand are used, the color after drying is the same as that of the conventional interior material. It has a completely new color, a mixture of natural clay and natural clay, and has a deep color tone. In addition, the coated surface and panel surface after drying make the atmosphere of the Japanese-style room more naturally due to the uneven softness and light color of the paper quality. When two or more kinds of colored sands having different colors are used as the colored sands, different colors are projected on the surface, and a Western-style atmosphere can be obtained.

[0020]

According to the present invention, the material for the interior material is composed of only natural materials,
By adding water to a mixture containing pulp as a main component and containing clay, a vegetable bond, and a vegetable fungicide, to form a paste-like interior material, even when used for interior materials in a general house, No special organic compound hypersensitivity measures or sick house measures are required, and no health problems occur. In addition, there is no waste of petroleum resources and no problems in waste disposal.

The use of indigenous aquatic plants as a raw material of pulp does not lead to deforestation, and the use of unbleached pulp can prevent the release of harmful substances such as residual chlorine from interior materials.

By using an inorganic coloring agent such as colored sand, stone powder, shell powder or the like as a coloring agent, a coloring that is not present in conventional interior materials can be obtained, and a health problem due to a chemical substance does not occur.
