200831750 九、發明說明 相關申請案之交叉參考 本申請案要求於2006年11月22日申請之韓國專利 申請案2006-115929之優先權，其內容整體倂入本文爲參 考。 【發明所屬之技術領域】 • 本發明係關於一種建築用陶瓷板及不可燃裝飾木質面 板’更特別是關於具有輕的重量、優越之現場裁斷性及不 可燃性之建築用陶瓷板及由基底片（例如以上之陶瓷板） 及藉不可燃黏合劑層以黏合至該基底板之裝飾木材所組成 之裝飾木質面板。 【先前技術】 通常，用來作爲建築內部面板之陶瓷板（例如石膏板 及類似者）是藉著將紙黏至平板狀石膏之雙側以維持結構 體且確保切變強度而製成。因優越之絕熱性及不可燃性， 以上之板已廣泛地作爲建築用之內部材料。然而，以上石 膏板缺點是偶合部分因水分而鬆脫以致結構體易於破碎且 當使用者指甲刮入石膏板時石膏板容易破裂。 爲改良以上問題，韓國專利公開案2004-99709揭示 一種由包含以下步驟之方法所製造之建築用板：混合鈣材 料（例如灰石）與矽材料（例如石英粉末或矽藻土），將 以上混合物連同以鎂爲底質之凝結劑一同攪拌以引起化學 -5- 200831750 鍵結且形成玻璃纖維層於反應物之前後表面上以增加切變 強度。 此外，韓國專利公開案2003-29 60揭示一種使用由氧 化鎂粉末及礦物粉末或植物性粉末所組成之原料製造建築 用材料的方法。然而，雖然依以上專利申請案所製造之建 築用材料有改良之防水性及強度，但缺點是板爲沉重的以 致彼難以處置且現場裁斷性是差的。 • 日本專利公開案2001-279860揭示一種藉以下步驟所 .製造之輕重量的不可燃板：添加增黏材料至含氧化鎂之可 溼性無機氧化物中，而後將之攪拌以獲得膏相且使含氣泡 之混合原料充分膨脹，且快速地熱形成該混合的原料。如 上述之輕重量的不可燃板保持於膨脹狀態，其中在板冷卻 後氣泡存於其中。然而，在以上日本申請案中所揭示之方 法問題是難以均勻地分散氣泡於原料中且最終物件之強度 不足。 • 與常用之陶瓷板（例如石膏板）比較時，如上述之以 鎂爲底質之建築用平板元件具有優越之防水性及強度，但 有重量重、現場裁斷性低及尺寸的改變比例大等缺點。 此外’建築物內邰最後常用壁材料例如壁紙或壁面板 來元成。作爲此種壁材料，常利用之壁材料爲黏合有木材 切片所得之裝飾木材的石膏板。然而，利用習知裝飾木材 的壁材料之問題是因欲被使用之板之沉重的重量使處置效 能降低且耐熱性又降低以致壁材料易被火焚傷。 200831750 【發明內容】 本發明欲解決上述問題；本發明目的是要提供一種具 有輕重量、優越強度、優越現場裁斷性及不可燃性之陶瓷 板。本發明之另一目的是要提供一種包含不可燃黏合劑層 之裝飾木質面板。 爲達成以上目的，依本發明之陶瓷板包含一包括以鎂 爲底質之無機化合物及輕重量之小片（chip)的核心層； ϋ 及形成在該核心層之一或二側表面上之表面層。 在此較佳地，以鎂爲底質之無機化合物是氧化鎂、氯 化鎂或氧化鎂及氯化鎂之混合物且輕重量之小片是用矽烷 偶合劑來表面處理。 較佳地，輕重量之小片是選自膨脹之聚苯乙烯、膨脹 之聚丙烯、膨脹之聚乙烯及氣溶膠顆粒之至少一發泡的小 片且該發泡的小片具有5至70倍之發泡放大率及0.015 至0.05克/立方公分之密度。 • 依本發明之陶瓷板表面層是經玻璃纖維強化之無機化 合物層，且較佳地，經玻璃纖維強化之無機化合物層是用 玻璃織物浸漬之以鎂爲底質之無機化合物或用以鎂爲底質 之無機化合物塗覆之玻璃纖維織物。 依本發明之裝飾木質面板包含基底片；藉不可燃黏合 劑層黏合至基底片之裝飾木材；及形成在裝飾木材 外線固化之透明樹脂層。 較佳地，裝飾木質面板之基底片是陶瓷板’其包含一 包括以鎂爲底質之無機化合物及輕重量之小片的核心層；。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 TECHNICAL FIELD OF THE INVENTION The present invention relates to a ceramic panel for construction and a non-combustible decorative wood panel. More particularly, it relates to a ceramic panel for building and a base material having light weight, superior on-site cutting property and non-combustibility. A sheet (such as 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, a ceramic plate (e.g., a gypsum board and the like) used as a building inner panel is produced 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 is agitated with a magnesium-based coagulant to cause chemical bonding to form a layer of glass fibers on the back surface before the reactants to increase the shear strength. Further, Korean Patent Publication No. 2003-29 60 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 material manufactured by the above patent application has 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 the following steps: 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 in the building, such as wallpaper or wall panels, 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; ϋ and a surface formed on one or both side surfaces of the core layer Floor. 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 glass fiber fabric coated with an inorganic compound of a substrate. 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 a transparent resin layer formed on the decorative wood outer line. Preferably, the base sheet of the decorative wood panel is a ceramic board comprising a core layer comprising a magnesium-based inorganic compound and a light weight small piece;

At least one of aluminum hydroxide, magnesium, aluminum oxide 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 g layer, and the material for discharging the anion is one selected from the group consisting of kiyoseki and rare earth minerals. DESCRIPTION OF SPECIFIC PERFORMANCES Hereinafter, 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 inorganic compound and a light weight die 1 21 core and upper and lower surfaces formed on the two side surfaces of the core layer, 13 0. Alternatively, the surface layer may be formed only on the core surface. The magnesium-based compound contained in the core layer of the ceramic plate according to the present invention is not particularly limited. Utilizing a mixture of magnesium oxide, magnesium chloride or magnesium chloride, it is preferred to use magnesium oxide or magnesium oxide and a mixture thereof. Preferably, in the above mixture, the content of magnesium chloride is 50 to 150 parts by weight with respect to 100 mg of magnesium oxide. It is not limited to this. The core layer of the ceramic plate of the present invention is made of magnesium as the base material, and the base resin is hydrated resin stone, and the odd figure is represented by magnesium 120; one layer of layer 110 is made of magnesium and magnesium. In addition, the present compound -8 - 200831750 additionally contains light weight tablets. 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% to 1% by weight relative to the entire core layer. However, the invention is not limited thereto. If the content of the light weight small pieces is less than 20% by volume or 1% by weight, the weight of the ceramic plate may not be lowered, and if the content of the light weight small pieces exceeds 60% by volume or 10% by weight, then When the weight piece is mixed with the core layer, the core layer 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, an amine-based decane coupling agent or an acrylic acid-based decane coupling agent. Preferred examples of the amine-based decane coupling agent are r-aminopropyltriethoxydecane, r-(2-aminoethyl)-aminopropyltrimethoxydecane, r - ( 2 Preferred examples of decyl coupling agents based on acrylic acid-based substrates, such as -aminoethyl)-aminopropylmethyldimethoxydecane, or r-anilinopropyltrimethoxydecane, and the like It is 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 of -9 - 200831750 or a method of dip coating may be mentioned, but the invention is not limited thereto. The shape of the light weight piece is not particularly limited. The light weight piece may have a different shape, such as a sphere and the like or an amorphous light weight 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 piece is preferably in the range of 0.1 to 3.0 mm. If the size of the light weight piece is less than 〇 1 mm, it is difficult to reduce the weight of the φ 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 low Φ at 0.015 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. 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 -10-200831750 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 exceeds 200 g 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 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 will be described with reference to Fig. 2 - 11 117 750 750 A raw material of a core layer is prepared by kneading a magnesium-based inorganic compound together with a light weight tablet or a magnesium-based inorganic compound separately with water. 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 310, 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 drum 311. Pressurize to form a surface layer. Subsequently, the raw material 203 of the core layer is laminated or coated on the surface layer and the raw material 2〇3 of the core layer and the surface layer are pressurized by the drum 312 to form a core layer. Then, the glass fiber fabric 204 and the surface layer raw material 202 are sequentially laminated on the core layer, the glass fiber woven fabric 04 and the surface layer raw material 02 and 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 -12-200831750 board of the present invention is described in more detail with reference to FIG. An inorganic sheet having incombustibility can be utilized without limitation as the base sheet 400 of the decorative wood panel according to the present invention, and a table, 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 40 1 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 hydrazine, magnesium hydroxide, oxidized cerium and cerium oxide as a flame retardant. Although not particularly limited, the content of the flame retardant is preferably from 20 to 50 parts by weight based on 100 parts by weight of the binder. If the content of the inhibitor is less than 20% by weight, the non-flammability 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.
