次に、本発明の実施の形態について図面を参照しながら説明する。まず、図１は、第１実施例に係る不燃板１１の一部を拡大して示す断面図であり、この不燃板１１は、水酸化マグネシウムを主体として平板状に形成されており、この不燃板１１の両面部１１ａ、１１ａ近傍位置には、ガラス繊維の芯材を網目状に編組して形成したガラス繊維ネット１２が設けられている。   Next, embodiments of the present invention will be described with reference to the drawings. First, FIG. 1 is an enlarged cross-sectional view showing a part of the incombustible plate 11 according to the first embodiment. The incombustible plate 11 is formed in a plate shape mainly composed of magnesium hydroxide. A glass fiber net 12 formed by braiding a glass fiber core material in a mesh shape is provided in the vicinity of both surface portions 11 a and 11 a of the plate 11.

不燃板１１の大きさの一例を上げると、例えば縦寸法が１２２０mmであり、横寸法が２４４０mmであり、厚さが３〜２１mmに形成される。   Taking an example of the size of the non-combustible plate 11, for example, the vertical dimension is 1220 mm, the horizontal dimension is 2440 mm, and the thickness is 3 to 21 mm.

不燃板１１の厚さが３mmの場合を例に上げると、両面部１１ａ、１１ａの約０．４mm内側に、ガラス繊維ネット１２が埋設した状態に設けられている（図１参照）。   Taking the case where the thickness of the non-combustible plate 11 is 3 mm as an example, the glass fiber net 12 is provided in an embedded state about 0.4 mm inside the double-sided portions 11a and 11a (see FIG. 1).

水酸化マグネシウムは、理論上は水とマグネシウムとが化学反応を起こしたものである。マグネシウムは、所謂、活性マグネシウムと、惰性マグネシウムとが有り、活性マグネシウムの成分が多い原材料の場合は、生産過程で水酸化マグネシウムに化学変化する量が多くなる。また、活性マグネシウムを多く含有すると、不燃板１１の腰の曲がりが良好になる。   In theory, magnesium hydroxide is a chemical reaction between water and magnesium. Magnesium includes so-called active magnesium and fertile magnesium, and in the case of a raw material having many active magnesium components, the amount of chemical change to magnesium hydroxide in the production process increases. Moreover, when a large amount of active magnesium is contained, the bending of the waist of the non-combustible plate 11 becomes good.

ガラス繊維ネット１２は、図２に示すように、ガラス繊維の芯材１２ａを網目状に編組して形成したものである。また、ガラス繊維ネット１２は、厚さが、例えば０．４mm程度のものが望ましく、重量は１ｍ２当たり０．２kgであることが望ましい。 As shown in FIG. 2, the glass fiber net 12 is formed by braiding glass fiber cores 12a in a mesh shape. Further, the glass fiber net 12 desirably has a thickness of about 0.4 mm, for example, and the weight is desirably 0.2 kg per 1 m 2 .

以上のような構成の不燃板１１は、天然の鉱物である水酸化マグネシウムを主体としており、ホルムアルデヒドやアスベスト等の有害な化学物質が含まれないので安全性が高い。そして、不燃板１１は、不燃性能が高いので煙や有害ガスが発生せず、また、耐候性、断熱性、遮音性、耐水性、防腐食性、防カビ性、加工性、施工性等に極めて優れた性能を有する。   The non-combustible plate 11 having the above-described structure is mainly composed of magnesium hydroxide, which is a natural mineral, and has high safety because it does not contain harmful chemical substances such as formaldehyde and asbestos. And since the incombustible plate 11 has high incombustibility, it does not generate smoke and harmful gases, and is extremely resistant to weather resistance, heat insulation, sound insulation, water resistance, corrosion resistance, mold resistance, workability, workability, etc. Excellent performance.

また、不燃板１１は、ネジやクギの保持力が高く、施工性に優れており、ノコギリやカッターによる加工性にも優れている。   Further, the non-combustible plate 11 has a high holding power for screws and nails, is excellent in workability, and is excellent in workability with a saw and a cutter.

そして、不燃板１１の両面部近傍位置にはガラス繊維ネット１２が設けられているので、耐衝撃性に優れ、曲げ強度が高い。特に、曲げ加工性に優れているので、壁面等の湾曲した部位に沿って、不燃板１１を配設することができる。つまり、曲面を有するデザイン性のある部位に対して、外装材又は内装材として使用することができるし、あるいは、曲げ加工が必要な家具やその他の種々の什器等にも使用することができる。   And since the glass fiber net | network 12 is provided in the double-surface part vicinity position of the incombustible board 11, it is excellent in impact resistance and bending strength is high. In particular, since it is excellent in bending workability, the incombustible plate 11 can be disposed along a curved portion such as a wall surface. That is, it can be used as an exterior material or interior material for a design part having a curved surface, or it can be used for furniture or other various furniture that needs to be bent.

更には、壁紙やシート等の貼り物については、不燃板１１との間にガスが発生しないので、その結果、下地処理の手間がかからない。また、塗装についても、塗料が不燃板１１に馴染みやすいので、美しい仕上がりになる。   Furthermore, since there is no gas generated between the non-combustible plate 11 and the pasting material such as wallpaper or sheet, the work of the groundwork is not required. In addition, the paint is also beautiful because the paint is easy to become familiar with the incombustible plate 11.

次に、縦寸法１２２０mm、横寸法２４４０mmの不燃板１１の、厚さが３mm、６mm、９mm、１２mm、１５mm、及び１８mmにそれぞれ形成したものの、密度（比率）、含水率％、曲げ破壊荷重Ｎ（ｋｇｆ）、釘抜き力Ｎ（ｋｇｆ）、難燃性８００℃釜内燃焼（３．５時間）時の釜内温升と燃焼時間と質量損失率、熱伝導率Ｗ／ｍ・ｋ、吸湿性ｋｇ／ｍ２（３．５時間水中付け）、吸水後長さ変化率、及び単位面積当たりの質量（ｋｇ／ｍ２）について測定した。その数値を表１に示す。 Next, the incombustible plate 11 having a vertical dimension of 1220 mm and a horizontal dimension of 2440 mm was formed with a thickness of 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, and 18 mm, respectively, but the density (ratio), moisture content%, bending fracture load N (Kgf), nail pulling force N (kgf), flame retardant temperature in the furnace at 800 ° C.

次に、図３及び図４に第２実施例に係る不燃板１３を示す。この第２実施例において、前記第１実施例の不燃板１１と同一部分には同一符号を付してその詳細は省略する。   Next, FIGS. 3 and 4 show the non-combustible plate 13 according to the second embodiment. In this 2nd Example, the same code | symbol is attached | subjected to the same part as the incombustible board 11 of the said 1st Example, and the detail is abbreviate | omitted.

この不燃板１３は、両面部に、不織布１４が設けられている。不織布１４は、比重（密度）が１５ｇ／ｍ２程度であることが望ましく、また、ガラス繊維を抄き込んだタイプであることが望ましい。 This incombustible plate 13 is provided with a nonwoven fabric 14 on both sides. The non-woven fabric 14 preferably has a specific gravity (density) of about 15 g / m 2 and is preferably a type in which glass fibers are made.

このように、不燃板１３の両面部に不織布１４が設けられていることによって、前述のガラス繊維ネット１２が設けられていることと相俟って、耐衝撃性に優れ、曲げ強度が高く、曲げ加工特性が一層向上する。また、耐候性、断熱性、遮音性、耐水性、防腐食性、防カビ性、加工性、施工性等に一層優れた性能を有することとなる。   Thus, by providing the nonwoven fabric 14 on both sides of the non-combustible plate 13, coupled with the above-described glass fiber net 12, excellent impact resistance, high bending strength, Bending characteristics are further improved. Moreover, it will have further superior performance in weather resistance, heat insulation, sound insulation, water resistance, corrosion resistance, mold resistance, workability, workability, and the like.

次に、第３実施例に係る不燃板及びその製造方法について説明する。まず、重量比が１５〜２５重量％の範囲の塩化マグネシウム（ＭｇＣｌ２・６Ｈ２Ｏ）と、重量比が５〜２０重量％の範囲の水（Ｈ２Ｏ）とを混合して溶液を作り、この溶液を約２４時間放置する。 Next, a non-combustible plate and a method for manufacturing the same according to the third embodiment will be described. First, a solution is prepared by mixing magnesium chloride (MgCl 2 · 6H 2 O) with a weight ratio in the range of 15 to 25% by weight and water (H 2 O) with a weight ratio in the range of 5 to 20% by weight. The solution is left for about 24 hours.

この溶液に、重量比が１５〜３５重量％の範囲の酸化マグネシウム（ＭｇＯ）を混合して、水酸化マグネシウム（Ｍｇ(ＯＨ)２）を発生させる。この水酸化マグネシウムの重量比は、３５〜４５重量％の範囲であることが望ましい。 This solution is mixed with magnesium oxide (MgO) having a weight ratio of 15 to 35% by weight to generate magnesium hydroxide (Mg (OH) 2 ). The weight ratio of magnesium hydroxide is desirably in the range of 35 to 45% by weight.

この水酸化マグネシウムに対して、重量比が５〜１０重量％の範囲の木片と、重量比が５〜１０重量％の範囲の真珠岩の粉末とを混合する。木片は、不燃板の軽量化及び発泡状態の促進のために混合される。また、木片の形状は、チップ状又はおが屑状であることが望ましい。真珠岩は、パーライトとも言われる火山岩の一種であり、所定温度で処理を施すと発泡体となる性質がある。   A piece of wood having a weight ratio of 5 to 10% by weight and nacreous powder having a weight ratio of 5 to 10% by weight are mixed with the magnesium hydroxide. The wood pieces are mixed to reduce the weight of the incombustible plate and promote the foamed state. Moreover, it is desirable that the shape of the piece of wood is a chip shape or a sawdust shape. Pearlite is a type of volcanic rock, also called perlite, and has the property of forming a foam when treated at a predetermined temperature.

この木片と真珠岩の粉末とを混合した水酸化マグネシウムに対して、２枚のガラス繊維ネットを引張しながら、ローラ圧延成形して平板を形成すると共に、この平板の両面部近傍位置にガラス繊維ネットを設ける。このガラス繊維ネットは、ガラス繊維の芯材を網目状に編組して形成したものである。   While rolling two glass fiber nets against magnesium hydroxide mixed with this piece of wood and pearlite powder, roller rolling is performed to form a flat plate, and glass fiber is positioned near both sides of the flat plate. Establish a net. This glass fiber net is formed by braiding a glass fiber core in a mesh shape.

このように形成した平板に対して、所定の乾燥処理を施す。まず、平板を約２４時間放置して自然乾燥させる。次に、自然乾燥させた平板を乾燥炉の中に入れて、約６０℃の温度で、約４時間乾燥させる。   A predetermined drying process is performed on the flat plate thus formed. First, the flat plate is left to dry for about 24 hours. Next, the naturally dried flat plate is put in a drying oven and dried at a temperature of about 60 ° C. for about 4 hours.

このような乾燥処理工程において、真珠岩の粉末が水酸化マグネシウム等の化学物質及び木片と化学反応をおこして発熱して発泡するので、平板が発泡状態に形成されることとなる。更に、乾燥炉から出した平板を、４日間放置して自然乾燥させる。   In such a drying process, the pearlite powder reacts with a chemical substance such as magnesium hydroxide and a piece of wood to generate heat and foam, so that a flat plate is formed in a foamed state. Furthermore, the flat plate taken out from the drying oven is left to stand for 4 days to dry naturally.

このように乾燥処理を施した平板を、前述のように、例えば縦寸法１２２０mm、横寸法２４４０mmに切断して不燃板を形成する。このように形成された不燃板は、発泡状態に形成されるので、不燃性、断熱性、遮音性等の性能が一層向上し、また、不燃板の軽量化が図れる。   As described above, the flat plate thus dried is cut into, for example, a vertical dimension of 1220 mm and a horizontal dimension of 2440 mm to form a non-combustible plate. Since the non-combustible plate formed in this way is formed in a foamed state, performances such as non-combustibility, heat insulation, and sound insulation are further improved, and the non-combustible plate can be reduced in weight.
