DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire protection interior material. More specifically, the present invention
A new fireproof interior material that is used in apartment houses, public facilities, and other living spaces, has a woody feel and high fire resistance, is lightweight, and has sufficient strength and excellent design, workability, and workability. It is about.

[0002]

2. Description of the Related Art Conventionally, as a wall material, a ceiling material, a ceiling material under an eave, and the like, calcium silicate, a gypsum board, an ALC panel, and the like are used in ordinary houses, apartment houses, and various other living spaces. Inorganic materials made of various materials are used.

[0003] The interior material made of this inorganic material has excellent moisture resistance and weather resistance and good fire resistance as compared with wood, and is relatively easy to unitize and produce, so that the cost can be reduced. In addition, it has the feature that the design of the living space is good.

[0004]

However, conventional non-wooden inorganic interior materials such as calcium silicate boards and gypsum boards are generally not suitable for use as interior facing materials. However, it is heavy, and it is easy to crack, chip, etc., so there is a problem in construction and workability. Also,
Rock wool sheathing material is used as a ceiling material, etc., but its strength as a material is small, so it is difficult to use it as a wall material that requires some strength, and when used as a ceiling material, its size is For example, 3 × 6
There is a disadvantage that it cannot be used with a large size such as a shaku. Further, the gypsum board has a disadvantage that the gypsum board itself needs to be replaced when the wallpaper is peeled off because the board itself has no strength in the interior use where the wallpaper is applied.

[0005] Moreover, these interior materials have limitations in terms of design. This is because the design is conventionally expressed by sticking a sheet on the surface of the interior material, but this sheet sticking is troublesome because it is performed on site, and has the drawbacks of wrinkling and peeling. This is because the. In order to solve such design problems, painting can be considered as an idea. However, many cement and gypsum-based materials generally show alkalinity, and adversely affect the durability of the coating by acting with moisture. In many cases, or adversely affect the finish such as unevenness in the suction of the paint and low surface strength.

[0006] As described above, the conventional inorganic and non-wooden interior materials are largely limited in design, workability, and workability. On the other hand, in recent years, with the growing interest in living spaces, the sense of woodiness such as softness and warmth has been reviewed, and demand for interior materials to utilize the characteristics of wood has been expanding.

[0007] However, since wood is not only difficult to improve in productivity due to unitization, it is also flammable. It is necessary to improve the fire resistance and fire resistance. Therefore, the above disadvantages of wood are solved,
As a measure to make the most of the characteristic wooden texture in the room, it is conceivable to use flame-resistant plywood made of wood itself and to laminate wood and non-wood interior materials. Can be

[0008] However, despite the ingenuity of such a flame-retardant plywood and lamination, there is an increase in weight, a great restriction in construction, and a processing in which cracks and chips are likely to occur due to the use of inorganic materials. There are concerns about shortcomings,
No practically satisfactory improvement has been realized so far.

The present invention has been made in view of the above circumstances, and has a woody feel of wood, is lightweight, has sufficient strength, and has little occurrence of cracks and chips. It is an object of the present invention to provide a new fireproof interior material having good workability and workability, and excellent fireproofness and design.

[0010]

According to the present invention, as an object to solve the above-mentioned problems, the inside is made of rock wool,
An interior material in which a flame-retardant / non-combustible sheet and flame-retardant treated wood are sequentially laminated on the front side, and a flame-retardant untreated wood and a flame-retardant / non-combustible sheet are successively laminated on the back side, and the surface is painted. The present invention provides a fireproof interior material characterized by:

Further, according to the present invention, the inside is made of rock wool, and a flame-retardant / non-combustible sheet and a flame-retardant treated wood are sequentially laminated on the front side, and a flame-retardant / non-combustible sheet and a flame-retardant untreated wood are laminated sequentially on the back side. Also provided is a fireproof interior material characterized in that the surface is painted and finished.

[0012]

The interior material of the fire-resistant material of the present invention is made of rock wool, and the flame-retardant wood treated by the flame-retardant treatment is disposed on the surface layer, so that it is lightweight and has sufficient strength.
It has good workability and workability with less occurrence of cracks and chips, and also has high fire protection. In addition, the fireproof interior material of the present invention can have its surface painted and painted. Various paintings (clear painting and coloring painting are possible for wood, but generally there are few clear paintings for other materials). ) Is possible, and as a result, high designability can be imparted.

There are no particular restrictions on the method of flame retarding wood, the chemicals used therefor, and the chemical content. For example, as a general method, impregnation under reduced pressure of a solution of a flame retardant, an immersion, application, or application of a fire retardant paint, etc., are exemplified, and examples of the agent include phosphorus-based and boric acid-based agents. As another flame-retardant treatment method, a method of producing an insoluble incombustible inorganic substance in wood by separately impregnating a chemical containing an anion and a cation, which react to form an insoluble inorganic substance insoluble in water, respectively. Is exemplified.

[0014] The paint finish is roughly classified into two types: a paint having a flat paint surface and a paint having an uneven paint surface.
There is no particular limitation. As the painted pattern with a painted surface having irregularities, for example, a sand wall pattern, a fiber pattern, an irregular pattern, a convex processing pattern, a crater pattern, a yuzu skin pattern, a stipple pattern,
Stucco patterns and the like are exemplified, but not limited to these. These uneven finishes are effective from the viewpoint of design. For example, sputter coating is known as a paint that expresses a stucco-like uneven pattern,
It is possible to create an embossed pattern such as a wallpaper, for example, by the unevenness. In particular, in interior applications such as recent general homes, sputter coating is preferable because patterns with unevenness have a high-class appearance and tend to be preferred.

The paint is not particularly limited. Examples thereof include water paint, oil paint, cellulose paint, natural resin paint, and synthetic resin paint which are generally used for wood. Paints can be used. Although there is no particular limitation on the inner rock wool (general term), commercially available rock wool cotton, rock wool sizing plate, and the like are preferable. The thickness is preferably about 6 to 40 mm, and the specific gravity is preferably 200 to 600 kg / m ³ in terms of availability and cost.

The fireproof interior material of the present invention has a flame-retardant / non-flammable sheet in the surface layer and the back layer in order to improve the strength and fire resistance while maintaining workability, workability and the like. The flame-retardant / non-flammable sheet can improve strength and fire resistance without deteriorating the features of light weight and good designability, workability, and workability. This is because even if the amount of combustible wood is the same, the flame retardant / non-combustible sheet firmly holds the carbonized layer during heating, and the carbonized layer blocks the flame and insulates the heat, thus improving the fire resistance. It is thought to improve.

Examples of the flame-retardant / non-combustible sheet include rock wool, flame-retardant resin, ceramics, glass, metals and the like, but those having a large weight are reflected only in the total weight of the interior material. However, it is not preferable in handling. Considering workability and workability, a material that is extremely difficult to cut or cut is also not preferable. From these viewpoints, costs, and the like, it is considered that a glass fiber sheet is generally suitable for a flame-retardant / non-flammable sheet.
