Field of the Invention The present invention relates to a ceramic panel for construction and a non-combustible decorative wood panel, and more particularly to a ceramic panel for construction and a substrate sheet having light weight, superior on-site cutting property and non-combustibility. (For example, the above ceramic plate) and a decorative wood panel composed of a non-combustible adhesive layer to be bonded to the decorative wood of the base plate. [Prior Art] Generally, ceramic plates (e.g., gypsum boards and the like) used as a building interior panel are made by adhering paper to both sides of a flat gypsum to maintain the structure and ensure shear strength. Due to its superior thermal insulation and non-flammability, the above boards have been widely used as internal materials for construction. However, the above-mentioned plaster board has a drawback in that the coupling portion is loosened by moisture so that the structure is easily broken and the gypsum board is easily broken when the user's nail is scraped into the gypsum board. In order to improve the above problem, Korean Patent Publication No. 2004-99709 discloses a building board manufactured by a method comprising the steps of: mixing a calcium material (for example, limestone) with a tantalum material (for example, quartz powder or diatomaceous earth), The mixture, together with a magnesium-based coagulant, was stirred to cause chemical-5-1355446 bonding and a glass fiber layer was formed on the back surface of the reactants to increase the shear strength. Further, Korean Patent Publication No. 2003-2960 discloses a method of producing a building material using a raw material composed of a magnesium oxide powder and a mineral powder or a vegetable powder. However, although the building materials manufactured according to the above patent application have improved water repellency and strength, the disadvantage is that the board is heavy so that it is difficult to handle and the field cutting property is poor. • Japanese Patent Publication No. 2001-279860 discloses a light weight non-combustible sheet manufactured by adding a tackifying material to a wettable inorganic oxide containing magnesium oxide, and then stirring it to obtain a paste phase and The bubble-containing mixed raw material is sufficiently expanded, and the mixed raw material is rapidly formed by heat. The light weight non-combustible sheet as described above is maintained in an expanded state in which bubbles are stored after the sheet is cooled. However, the method disclosed in the above Japanese application is that it is difficult to uniformly disperse bubbles in the raw material and the strength of the final article is insufficient. • Compared with commonly used ceramic plates (such as gypsum board), the above-mentioned magnesium-based flat panel elements have superior water resistance and strength, but have heavy weight, low on-site cutting and large proportion change in size. And so on. In addition, the last common wall material inside the building, such as a wallpaper or wall panel, is used. As such a wall material, a wall material which is often used is a gypsum board to which decorative wood obtained by wood chipping is bonded. However, the problem of using the wall material of the conventional decorative wood is that the heavy weight of the board to be used lowers the handling effect and the heat resistance is lowered so that the wall material is easily burned by fire. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a ceramic board having light weight, superior strength, superior field cutting property and nonflammability. Another object of the present invention is to provide a decorative wood panel comprising a layer of non-combustible adhesive. In order to achieve the above object, a ceramic plate according to the present invention comprises a core layer comprising a magnesium-based inorganic compound and a light weight chip; and a surface layer formed on one or both side surfaces of the core layer . Preferably, the inorganic compound based on magnesium is magnesium oxide, magnesium chloride or a mixture of magnesium oxide and magnesium chloride and the light weight tablets are surface treated with a decane coupling agent. Preferably, the light weight tablet is at least one foamed piece selected from the group consisting of expanded polystyrene, expanded polypropylene, expanded polyethylene, and aerosol particles and the foamed tablet has 5 to 70 times the hair. Bubble magnification and density from 0.015 to 0.05 g/cm 3 . The surface layer of the ceramic plate according to the present invention is a glass fiber-reinforced inorganic compound layer, and preferably, the glass fiber-reinforced inorganic compound layer is a magnesium-based inorganic compound impregnated with a glass fabric or used for magnesium. A semi-organic inorganic compound coated glass fiber fabric. The decorative wood panel according to the present invention comprises a base sheet; decorative wood adhered to the base sheet by a non-combustible adhesive layer; and an ultraviolet-cured transparent resin layer formed on the decorative wood. Preferably, the base sheet of the decorative wood panel is a ceramic plate comprising a core layer comprising a magnesium-based inorganic compound and a light weight small piece; 1355446 and formed on one or both side surfaces of the core layer. Surface layer. Here, the adhesive layer is formed by using a binder containing a flame retardant and using an amino carboxylic acid vinegar as a substrate, an acrylic-based adhesive, or an epoxy-based adhesive. The flame retardant is selected from at least one of aluminum hydroxide, magnesium hydroxide 'alumina, and cerium oxide. The material for discharging the negative ions is added to at least one selected from the group consisting of a binder layer and a cured resin layer, and the material for discharging the negative ions is one selected from the group consisting of tourmaline, kiyoseki, and rare earth minerals. DESCRIPTION OF SPECIFIC PERFORMANCE OF THE INVENTION In the following, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. As illustrated in Fig. 1, the ceramic plate according to the present invention comprises a core layer 120 comprising a magnesium-based inorganic compound and a light weight plate 121; and is formed above and below the two side surfaces of the core layer. Surface layer 110, 1 30. On the other hand, the surface layer may be formed only on one side surface of the core layer. The magnesium-based inorganic compound contained in the core layer of the ceramic plate according to the present invention is not particularly limited. A mixture of magnesium oxide, magnesium chloride or magnesium oxide and magnesium chloride is preferably used, or magnesium oxide or a mixture of magnesium oxide and magnesium chloride. Preferably, in the above mixture, the content of magnesium chloride is 50 to 150 parts by weight with respect to 100 parts by weight of magnesium oxide. However, the present invention is not limited to this. The ceramic plate core layer of the present invention comprises, in addition to the magnesium-based inorganic compound -8 - 1355446, a light weight tablet. By suitably adding light weight tablets, it is possible to prevent the strength of the ceramic plate from being lowered and the weight of the ceramic plate to be reduced. Preferably, the light weight tablet is present in an amount of from 20 to 60% by volume and from 1.0 to 1% by weight relative to the entire core layer. However, the invention is not limited thereto. If the content of light weight small pieces is less than 20% by volume or 1% by weight, the weight of the ceramic plate may not decrease, and if the content of light weight pieces exceeds 60% by volume or 10% by weight, then When the weight piece is mixed with the core layer, the core layer φ is deformed and it is impossible to obtain the desired ceramic plate strength. In the present invention, light weight tablets are preferably surface treated with a decane coupling agent. By surface treatment of light weight tablets, the coupling force between the inorganic compound and the light weight plate or between the glass fiber reinforced inorganic compound applied to the outside of the core layer and the light weight plate can be enhanced in the core layer. Anyone who is commonly used in this field can be utilized without limitation as a decane coupling agent. However, it is preferred to use, for example, a decane coupling agent having an amine as a base > a decane coupling agent or an acrylic acid based substrate. Preferred examples of φ alkane coupling agent based on an amine are T-aminopropyltriethoxydecane, r-(2-aminoethyl)-aminopropyltrimethoxydecane, r - ( 2-aminoethyl)-aminopropylmethyldimethoxydecane, or r-anilinopropyltrimethoxydecane, and the like, and preferably an acrylic based decane coupling agent Examples are r-methacryloxypropyltrimethoxydecane or r-methylpropoxypropyldimethoxydecane and the like. However, the invention is not limited thereto. As a method of surface-treating a light weight tablet with a decane coupling agent, a method commonly used in the field of the present invention can be used. For example, a method of spray coating -9- 1355446 or a method of dip coating may be mentioned, but the invention is not limited thereto. The shape of the light weight small piece is not particularly limited, and the light weight small piece may have a different shape such as a spherical shape and the like or an amorphous light weight small piece may be used. Further, if the size of the light weight small piece is smaller than the thickness of the core layer, the size of the light weight small piece is not particularly limited. However, in view of the strength of the ceramic plate, the size of the light weight small piece is preferably in the range of 0.1 to 3.0 mm. If the size of the light weight piece is less than 0.1 mm, it is difficult to reduce the weight of the ceramic plate, and if the size of the light weight piece is 3.0 mm or more, the strength of the ceramic plate can be lowered. As a light weight tablet, any of those commonly used in the field of the present invention can be used without limitation. However, it is preferred to use a small piece of at least one foam selected from the group consisting of expanded polystyrene, expanded polypropylene, expanded polyethylene, and aerosol particles as a light weight tablet. Although not particularly limited, the foamed pellet preferably has a foaming magnification of 5 to 70 times and a density of 0.015 to 0.05 g/cm 3 . If the foaming magnification exceeds 70 times or the density is less than 0.01 I5 g/cm 3 , there is a problem that the strength of the final ceramic plate can be lowered. On the contrary, if the foaming magnification is less than 15 times or the density exceeds 〇·〇5 g/cm 3 , there is a problem that the weight of the ceramic plate cannot be sufficiently lowered. As long as the additive does not affect the effects of the present invention, one or more additives selected from the group consisting of wood powder, perlite, a foaming agent and a curing controlling agent may be suitably added to the core layer of the ceramic board of the present invention. In the ceramic board of the present invention, the surface layer is preferably a glass fiber-reinforced inorganic compound layer. Preferably, a glass fiber fabric impregnated with a glass fiber fabric and having an inorganic compound of magnesium -10- 1355446 or an inorganic compound coated with magnesium as a substrate can be used as a glass fiber reinforced inorganic compound layer. As the glass fiber fabric, any person who is commonly used in the related art of the present invention can be used without limitation. However, the glass fiber fabric is preferably a combination of a glass fiber woven fabric, a glass fiber woven fabric or a glass fiber woven fabric and a non-woven fabric. Preferably, the glass fibers have a mass of from 20 to 200 grams per square meter (20 to 200 grams per square meter). If the mass of the glass fiber φ dimension exceeds 200 grams per meter, there is a problem that the weight of the ceramic plate cannot be sufficiently reduced. The magnesium-based inorganic compound used in the glass fiber-reinforced inorganic compound is preferably magnesium oxide, magnesium chloride or a mixture of magnesium oxide and magnesium chloride. More preferably, the inorganic compound based on magnesium is magnesium oxide or a mixture of magnesium oxide and magnesium chloride. Further, in view of the strength of the reinforced ceramic plate, one or more additives selected from the group consisting of wood powder, wander iron, a foaming agent, and a curing control agent may be suitably added to the inorganic compound which is based on magnesium. The thickness of the φ ceramic plate is not limited and can be selected from a suitable range in accordance with the field to which the ceramic plate according to the present invention is applied. However, the thickness of the ceramic plate is preferably in the range of 3 to 15 mm. Further, a woven fabric layer composed of a woven fabric may be additionally attached to one or both surfaces of the ceramic plate of the present invention. By attaching the woven fabric layer to the ceramic plate, the strength of the ceramic plate or the coupling strength between the ceramic plate and other internal materials can be increased and the decorative effect can be enhanced. The ceramic board for construction of the present invention can be produced by a method which has been conventionally used in the related art of the present invention. In the following, an example of the method is described with reference to Fig. 2 - 1355446. A magnesium-based inorganic compound and a light weight small piece or a magnesium-based inorganic compound are separately kneaded with water to prepare a core layer of the raw material 203. And the raw material 202 of the surface layer. Then, the raw material 202 of the surface layer is laminated or coated on the flat mold 301, the glass fiber fabric 20 1 is laminated on the surface layer raw material 202, and the raw material of the glass fiber fabric 201 and the surface layer is transported by the roller 3 1 1 Pressurize to form a surface layer. Subsequently, the raw material of the core layer is laminated or coated on the surface layer and the raw material 203 and the surface layer of the core layer are pressurized by the drum 3 12 to form a core layer. Then, the glass fiber fabric 204 and the surface layer material 202 are sequentially laminated on the core layer, the glass fiber fabric 204 and the surface layer material 202 are then pressurized by the roller 313 so that the ceramic plate of the present invention can be produced. In the method of manufacturing a ceramic board of the present invention, a process for laminating a woven fabric may be added before and/or after the process for forming the surface layer. Further, a glass fiber reinforced inorganic compound sheet produced by impregnating or coating a glass fiber fabric with a magnesium-based inorganic compound can be used as the surface layer. In the method for producing a ceramic plate of the present invention, either a continuous method or a batch method can be utilized. In the method for producing a ceramic plate of the present invention, an inundation aging process may be additionally performed to suppress cracks caused by excessive aging and to transmit harmful components contained in the production method. The decorative wood panel according to the present invention comprises a base sheet; decorative wood adhered to the base sheet by a non-combustible adhesive layer: and an ultraviolet-curable transparent resin layer formed on the wood. In the following, the decorative wood surface -12-1355446 plate of the present invention is described in more detail with reference to Figure 3. An inorganic sheet having non-combustibility can be utilized without limitation as the base sheet 400 of the decorative wood panel according to the present invention, and a magnesium sheet, a cement board or a ceramic board such as a gypsum board can be listed as an example of such a board. However, the ceramic plate of the present invention is preferably used as a substrate sheet. By using the ceramic board of the present invention, it is possible to enhance the nonflammability of the decorative wood panel. The adhesive layer 401 of the decorative wood panel of the present invention is non-flammable, and the non-flammable agent layer can be obtained by including a flame retardant in the adhesive. As the above adhesive, a binder which is commonly used in the field of the present invention can be used without limitation. Preferably, a urethane-based binder, an acrylic-based binder or an epoxy-based binder is used as the binder. The flame retardant contained in the binder is not particularly limited. However, it is preferred to use at least one selected from the group consisting of aluminum hydroxide, magnesium hydroxide, aluminum oxide and cerium oxide as a flame retardant. Although not particularly limited, the content of the flame retardant is preferably 20 to 50 parts by weight based on 1 part by weight of the binder. If the content of the inhibitor is less than 20% by weight, the nonflammability may be insufficient. If the content of the flame retardant exceeds 50 parts by weight, the adhesive adhesion may be lowered. Natural decorative wood chips which are commonly used in the art can be used as the decorative wood layer 402 used in the decorative wood panel of the present invention. The chips can be made by cutting the wood into thin slices. Although not particularly limited, the thickness of the decorative wood layer is preferably from 0.2 to 0.5 mm. In the decorative wood panel of the present invention, any material conventionally used in the art can be used without limitation to form a UV-curable transparent resin -13 - 1355446 layer 403. Generally, the non-flammability of the material for forming the ultraviolet-curable transparent resin layer is poor. Therefore, the ultraviolet-curable resin layer is advantageously formed as thin as possible. For example, the thickness of the ultraviolet-curable transparent resin layer is preferably less than 0 - 3 mm', however, the invention is not limited thereto. Further, the lower limit of the thickness of the ultraviolet-curable resin layer 403 is not particularly limited, but the thickness of the ultraviolet-curable resin layer is preferably 〇1 mm or more. In the decorative wood panel of the present invention, a material for discharging negative ions may be added to the adhesive layer 401 and/or the ultraviolet-curable transparent resin layer 403. The decorative wood panel of the present invention can release as many negative ions as those released by natural forests due to the material that emits negative ions. Any material capable of releasing negative ions can be utilized as a material for discharging negative ions without limitation. Although not particularly limited, it is preferred to use one selected from the group consisting of tourmaline, odd rock, and rare earth minerals as a material for discharging negative ions. The content of the negative ion-releasing material is 10 to 30 parts by weight with respect to 100 parts by weight of the adhesive layer or the ultraviolet-curable transparent resin layer or the adhesive layer and the ultraviolet-curable transparent resin layer. The decorative wood panel of the present invention can be manufactured by methods conventionally used in the art. Although not particularly limited, one of the methods of manufacturing a wood panel is as follows. That is, a base sheet, a decorative wood, a non-flammable adhesive, and an ultraviolet-curable resin composition are prepared, and the base sheet and the decorative wood are bonded to each other via a non-combustible adhesive. Subsequently, the decorative wood adhered to the base sheet is coated with a UV-curable resin composition and then cured to complete the decorative wood panel. -14- 1355446 In the following, the invention is described in more detail by way of examples according to the invention and comparative examples of common techniques.
