Description
本発明は、ダンボール板または厚紙間に、アルミニュウム箔等を積層した、不燃性を有して、軽量であるところから運搬、組立てなどの取扱い性にも優れた、フスマ、建具、間仕切り、壁、家具等に使用するダンボールボードに関するものである。 The present invention provides fusuma, fittings, partitions, walls, etc., which are made by laminating aluminum foil or the like between cardboard boards or cardboard, are nonflammable, and are lightweight and have excellent handling properties such as transportation and assembly. This relates to cardboard boards used for furniture, etc.
従来、無機質繊維断熱材と化粧表皮材の間にアルミニュウム箔を介装した断熱材（特許文献１）、あるいはガラス繊維織物の一側面または両面にアルミニウム箔又はアルミニウム蒸着フィルムを貼合わせたものまたはコーティングしたもの（特許文献２）が存する。これら従来の断熱材は、ダンボールボードに関するものではなく、また、表面にアルミニュウム箔又はフィルムが形成されるため、衝撃、摩擦を受けやすく、損傷をきたすことが多い欠点を有する。そして軽量化に意を用いたものでもない。 Conventionally, a heat insulating material in which an aluminum foil is interposed between an inorganic fiber heat insulating material and a decorative skin material (Patent Document 1), or a material in which an aluminum foil or an aluminum vapor-deposited film is laminated or coated on one or both sides of a glass fiber fabric. There is one (Patent Document 2). These conventional heat insulating materials are not related to cardboard boards, and since aluminum foil or film is formed on the surface, they are susceptible to impact and friction, and have the disadvantage that they often cause damage. And it doesn't even take into account weight reduction.
さらにまた、後者のものの製造は、図５に示す製造工程においてコーティング液に浸漬する工程を要し、さらにアルミ箔のコーティング層を片面に有するものをローラ移送するので難しく製造に手間を要する。 Furthermore, manufacturing the latter requires a step of immersing it in a coating liquid in the manufacturing process shown in FIG. 5, and further requires transferring the aluminum foil coating layer on one side with a roller, which is difficult and time-consuming.
本発明は、ダンボール板間または2枚の紙シート間に、アルミニュウム箔を積層することで、不燃性を有し、かつ軽量であるところから運搬、組立てなどの取扱い性に優れた、フスマ、建具、間仕切り、壁、家具等に使用できる不燃ダンボールボードを提供するものである。 The present invention is made by laminating aluminum foil between cardboard boards or between two paper sheets, making it non-combustible and lightweight, making it easy to handle in transportation and assembly. The present invention provides a noncombustible cardboard board that can be used for partitions, walls, furniture, etc.
通常、ダンボール板１１は、図３に示すようにライナーシート１２と呼ばれる平坦な紙シート間に、波状に折り曲げたコルゲートと呼ばれる中芯紙１３を挟んで積層してある。この中芯紙１３とライナーシート１２との貼り合わせは、コルゲートの波形の凹凸部と表裏の平坦なライナーシート１２との接触部分ａを糊付けして行っている。そしてフスマ、間仕切り等の場合、ライナーシート１２の表面に、さらに任意のカラーおよび模様の化粧紙を貼り付けて仕上げる。 Normally, the corrugated board 11 is laminated with corrugated core paper 13, called corrugated paper, sandwiched between flat paper sheets called liner sheets 12, as shown in FIG. The core paper 13 and the liner sheet 12 are bonded together by gluing the contact portion a between the corrugated corrugated portion and the flat liner sheet 12 on the front and back sides. In the case of a bran, a partition, etc., decorative paper of an arbitrary color and pattern is further pasted on the surface of the liner sheet 12 to finish it.
しかしながら、アルミニュウム箔のような薄いシートを、ダンボールボードの成型ライン（図５参照）に、ダンボールあるいは紙シートからなる中芯紙に代えて挿入し、コルゲート成型することは、強度に対応できず不可能である。そのため、図４に示すように、フィルム１４を中芯紙１３に重ね合わせてコルゲート成型することが考えられるが、薄いシート１４を波形の凸部bだけでライナーシート１２に接着させることは接着不十分となる。 However, inserting a thin sheet such as aluminum foil into the molding line of a corrugated board (see Figure 5) instead of a core made of cardboard or paper sheets and performing corrugated molding is not suitable for strength. It is possible. Therefore, as shown in FIG. 4, it is conceivable to overlay the film 14 on the core paper 13 and perform corrugate molding, but it is not possible to adhere the thin sheet 14 to the liner sheet 12 only with the corrugated convex portions b. It will be enough.
そこで本発明は、不燃性であるアルミニュウム箔の薄いシートの表裏を、接着剤を介して紙シートで挟んで積層してダンボール積層板を作成し、さらに前記同様のダンボール積層板をコルゲート成型して中芯紙とし、さらに前記と同様のダンボール積層板で挟み、コルゲート成型した中芯紙のアルミニュウム箔部分ではなく、中芯紙の凹凸部分とを接着して本発明の不燃性ダンボールボードを製作した。 Therefore, the present invention creates a cardboard laminate by sandwiching the front and back sides of thin sheets of non-combustible aluminum foil between paper sheets with an adhesive, and then corrugates the same cardboard laminate as described above. The non-combustible cardboard board of the present invention was produced by using core paper as a core paper, sandwiching it between cardboard laminates similar to those described above, and bonding the uneven parts of the core paper instead of the aluminum foil part of the corrugated core paper. .
以上のように製作することで、コルゲート成型された中芯紙のアルミニュウム箔と紙シートとが全面接着でき、さらに表裏面紙（ライナーシート）の間に積層して通常のダンボールボードの成型ラインと同様に成型することで、中芯紙の凹凸部と表裏のライナーシートとが紙同士の接着となり、強固な接着が行われる。 By manufacturing as described above, the aluminum foil of the corrugated core paper and the paper sheet can be bonded on the entire surface, and it can also be laminated between the front and back sheets (liner sheets), making it possible to use it on a normal corrugated board molding line. By molding in the same manner, the uneven portions of the core paper and the front and back liner sheets become adhered to each other, resulting in strong adhesion.
ダンボールボードに、アルミニュウム箔層が三重に挿入されるので、十分な不燃性が得られ、さらに、建築材としての反りの対処を十分に図れ、ダンボールは軽量であるため、運搬、組立てなどの取扱い性に優れた建具、間仕切り、壁、家具等用のダンボールボードが提供できる。 Three layers of aluminum foil are inserted into the cardboard board, making it sufficiently non-combustible.Furthermore, cardboard is lightweight, making it easy to handle when transporting, assembling, etc. We can provide cardboard boards for fittings, partitions, walls, furniture, etc. with excellent durability.
本発明のダンボールボードの一実施形態について説明する。
図３は、従来から存する通常のダンボール板１１の一部断面を示す。
２枚のダンボールからなるライナーシート１２と、その２枚のライナーシート１２,１２間に、波形にコルゲート成形されたダンボール製の中芯１３が各波の凹凸部aで表裏ともに接着されて製造される。
An embodiment of the cardboard board of the present invention will be described.
FIG. 3 shows a partial cross section of a conventionally existing normal cardboard board 11.
A liner sheet 12 made of two pieces of cardboard, and a core 13 made of corrugated cardboard corrugated between the two liner sheets 12, 12 are bonded on both the front and back sides at the uneven portion a of each wave. Ru.
その他の構造のダンボール板として、前記基本構造の１層のダンボール板に、さらにコルゲートされた中芯１３がライナーシートの上に、繰り返し積層される２層、３層と厚くなる多層ダンボール板が存する。 As a corrugated board with other structure, there is a multi-layered corrugated board in which a corrugated core 13 is repeatedly laminated on a liner sheet in two or three layers in addition to the one-layered corrugated board of the basic structure. .
図１に、本発明の不燃性ダンボールボードで使用するダンボール構成板1の構造を示す。
ダンボール構成板１は、二枚の紙シート２,３の間に、両面に接着剤を塗布したアルミニュウム箔４を挿入して積層してある。アルミニュウム箔４の両面に塗布する接着剤５には、全面に樹脂ラミネートあるいは希釈溶剤および硬化剤を加えた低密度ポリエチレン系接着剤を使用している。
FIG. 1 shows the structure of a cardboard construction board 1 used in the noncombustible cardboard board of the present invention.
The cardboard construction board 1 is laminated by inserting an aluminum foil 4 coated with adhesive on both sides between two paper sheets 2 and 3. As the adhesive 5 applied to both sides of the aluminum foil 4, a resin laminate or a low density polyethylene adhesive to which a diluting solvent and a hardening agent are added is used on the entire surface.
図２に、前記ダンボール構成板1を使用して製作した本発明の不燃性ダンボールボードを示す。
本発明の不燃性ダンボールボードは、前記ダンボール構成板１,1の間に、同様のダンボール構成板1をコルゲート加工した中芯紙６を間に挿入し積層してある。コルゲート加工された中芯紙６は、各凹凸部７で、その両面に積層されるダンボール構成板１,１の紙シート２,３の面と接着して、不燃性ダンボールボードが製造される。
FIG. 2 shows a noncombustible cardboard board of the present invention manufactured using the cardboard component board 1 described above.
The noncombustible corrugated cardboard board of the present invention has a core paper 6 obtained by corrugating the same corrugated cardboard constituting plate 1 inserted between the corrugated cardboard constituting plates 1, 1, and laminated therebetween. The corrugated core paper 6 is adhered to the surfaces of the paper sheets 2, 3 of the corrugated cardboard component boards 1, 1 laminated on both sides at each uneven portion 7, thereby producing a non-combustible corrugated cardboard board.
ダンボール構成板1を構成する表裏二枚の紙シート２,３は、一方の面を表面（２）とし、他方の面を内側面（３）とするので、内側面シート３は、中芯紙６との接着性を良好とするためにチップ状の紙シートとするのが好ましい。したがって、表裏二枚の紙シートは、中芯紙7側にチップ状の紙シート３が位置するように表面紙シート２と逆向きの層となるように配置するのが良い。 The two paper sheets 2 and 3 that make up the corrugated board 1 have one surface as the front surface (2) and the other surface as the inner surface (3), so the inner surface sheet 3 is made of core paper. It is preferable to use a chip-shaped paper sheet in order to improve the adhesion with 6. Therefore, it is preferable that the two front and back paper sheets are arranged so that the chip-shaped paper sheet 3 is located on the core paper 7 side, so that they form a layer in the opposite direction to the front paper sheet 2.
基本の構成材となるダンボール構成板1の仕様は表１の通りの配置であり、表面のセルロース紙２および内面のチップボール原紙３とはポリエチレン系接着剤５で接着してある。 The specifications of the cardboard construction board 1, which is the basic construction material, are arranged as shown in Table 1, and the cellulose paper 2 on the surface and the chipboard base paper 3 on the inside are adhered with a polyethylene adhesive 5.
そこで本発明は、不燃性を有するアルミニュウム箔の薄いシートを中芯紙の間に挟んで積層し、積層シートとしてコルゲート成型することで、フィルムと中芯紙の両面紙シートとが全面接着でき、コルゲート成型されたアルミニュウム箔と中芯紙との積層シートを通常のダンボールボードの成型ラインと同様に成型でき、コルゲートされた中芯紙の凹凸部と表裏のライナーシートとが紙同士の接着となり、強固な接着が行なわれる不燃性を有するダンボールボードを製作した。 Therefore, in the present invention, a thin sheet of non-combustible aluminum foil is sandwiched between core papers and laminated, and the laminated sheet is corrugated, so that the film and the double-sided paper sheet of the core paper can be fully bonded. A laminated sheet of corrugated aluminum foil and core paper can be molded in the same way as a normal corrugated board molding line, and the uneven parts of the corrugated core paper and the front and back liner sheets become adhesives between the papers. We have manufactured a non-combustible cardboard board with strong adhesion.
本発明で製作したダンボールボードは、一般財団法人ベターリビングが制定した「防耐火性能試験・評価業務方法書」に規定する「準不燃性能試験・評価方法」に基づき、発熱性試験およびガス有害性試験を行った結果。次のような適合結果を得られた。
