Abstract
Description
本発明は、内装材や家具材などに使用される紙管に関する。 The present invention relates to a paper tube used for interior materials and furniture materials.
紙管は、軽量で且つ所定の強度を持たせることが出来る。
そして、特許文献１では、複数個の紙管を並列しシートで連結して紙管パネルとし、その紙管パネルを、間仕切り、天井材、床材、扉材などの内装材や家具材の構成部品として使用することが提案されている。
しかし、従来の紙管は、紙を材料とするために燃えやすいという課題を有している。
The paper tube is lightweight and can have a predetermined strength.
In Patent Document 1, a plurality of paper tubes are juxtaposed and connected with a sheet to form a paper tube panel, and the paper tube panel is configured of interior materials such as partitions, ceiling materials, floor materials, door materials, and furniture materials. It has been proposed to be used as a part.
However, the conventional paper tube has a problem that it is easy to burn because it uses paper as a material.
本発明は、上記のような課題に着目してなされたもので、燃え難い紙管を提供することを目的とする。 The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a paper tube that is difficult to burn.
課題を解決するために、本発明の一態様である紙管は、無機質紙を複数積層した状態に形成されている。
上記無機質紙は、無機材料の主成分がケイ酸マグネシウムであることが好ましい。
In order to solve the problem, a paper tube which is one embodiment of the present invention is formed in a state where a plurality of inorganic papers are stacked.
In the inorganic paper, the main component of the inorganic material is preferably magnesium silicate.
本発明の態様によれば、紙管を無機質紙から構成することで、火炎を貫通し難くい不燃性を有する。また耐熱保形性を有して、火事などで熱が加えられても形が崩れにくくなる。
例えば、無機質紙の無機材料の主成分をケイ酸マグネシウムとすることで、より確実に不燃性を有する紙管を提供可能となる。
According to the aspect of the present invention, the paper tube is made of inorganic paper, so that it has nonflammability that hardly penetrates the flame. In addition, it has heat-resistant shape retention so that it is less likely to collapse even when heat is applied by a fire or the like.
For example, when the main component of the inorganic material of the inorganic paper is magnesium silicate, a paper tube having nonflammability can be provided more reliably.
ここで、居住、商業用施設、駅舎、空港等公共施設等の建築物において、火災時に燃え広がらないようにするために、一定の規模・用途に供する、居室や廊下・階段等の避難経路等は、その壁や天井の仕上げ材に、それぞれの要求性能に応じた防火材料（不燃材料、準不燃材料及び難燃材料）を用いなければならないことが、法律（施行令第１２９条）で義務付けられている。 Here, in buildings such as residences, commercial facilities, station buildings, airports, and other public facilities, evacuation routes such as living rooms, corridors, stairs, etc. are provided for a certain scale and use so that they do not spread during a fire. The law (Enforcement Ordinance Article 129) mandates that fireproof materials (non-combustible materials, semi-incombustible materials and flame-retardant materials) corresponding to the required performance must be used for the finishing materials of the walls and ceilings. It has been.
このような場所に紙管で内装材や家具材を構成しても、本発明の紙管であれば、美観を損なうことなく、不燃性を付与することが出来る。
ここで、本発明の紙管が有する不燃性は、ＩＳＯ５６６０−１に準拠したコーンカロリ燃焼試験に準拠し、上記紙管の時間に対する総発熱量及び時間に対する発熱速度を求めた際に、（ｉ）加熱開始後２０分間の総発熱量が８ＭＪ／ｍ２以下であり、（ｉｉ）加熱開始後２０分間、最大発熱速度が１０秒以上継続して２００ｋＷ／ｍ２を超えず、かつ（ｉｉｉ）加熱開始後２０分間、防火上有害な外側から内側まで貫通する亀裂及び穴がないことを満たす不燃性を有することが好ましい。
Even if the interior material or the furniture material is configured with a paper tube in such a place, the paper tube of the present invention can impart nonflammability without impairing the aesthetic appearance.
Here, the nonflammability of the paper tube of the present invention is determined based on the corn calorie combustion test based on ISO 5660-1 and when the total calorific value with respect to time of the paper tube and the heat generation rate with respect to time are obtained (i) The total calorific value for 20 minutes after the start of heating is 8 MJ / m 2 or less, (ii) 20 minutes after the start of heating, the maximum heat generation rate continues for 10 seconds or more and does not exceed 200 kW / m 2 , and (iii) the heating It is preferable to have incombustibility satisfying the absence of cracks and holes penetrating from outside to inside that are harmful to fire prevention for 20 minutes after the start.
次に、本発明の実施形態について図面を参照して説明する。
本実施形態の紙管は、無機質紙を複数積層して形成される。
無機質紙の積層数は特に限定は無いが、無機質紙の積層数が多いほど強度や剛性が確保されることから、紙管を用いる用途で要求される強度や剛性に応じて積層数を設定すればよい。
Next, embodiments of the present invention will be described with reference to the drawings.
The paper tube of this embodiment is formed by laminating a plurality of inorganic papers.
The number of layers of inorganic paper is not particularly limited, but as the number of layers of inorganic paper increases, the strength and rigidity are secured, so the number of layers can be set according to the strength and rigidity required for the application using paper tubes. That's fine.
但し、後述のように、十分な不燃性を得るという点では４〜７層の積層が好ましい。
紙管の製造方法は、特に限定されず、公知の製造方法で製造すればよい。例えば特開昭６３−２４９６３７号公報等に記載のように、芯材に無機質紙を螺旋状に巻き付けることで積層してスパイラル紙管として作成したり、特開平７−２８５１８４号公報等に記載のように、芯材に順次紙を巻き付けてリニア紙管として作成したりすればよい。
However, as will be described later, 4 to 7 layers are preferable in terms of obtaining sufficient incombustibility.
The manufacturing method of the paper tube is not particularly limited, and may be manufactured by a known manufacturing method. For example, as described in JP-A-63-249637, etc., an inorganic paper is spirally wound around a core material to form a spiral paper tube, or as described in JP-A-7-285184, etc. In this way, it is possible to create a linear paper tube by sequentially winding paper around the core material.
紙管の断面形状は、円形形状でも、角形形状でも他の形状でも、筒形状であれば特に限定されない。
紙管を形成するために使用する紙は、無機質紙を採用する。
無機質紙は、無機繊維と無機粉体とからなる無機材料が全体の８０重量％以上含有して構成され、その他の成分として例えばパルプ繊維及び有機バインダを含有して構成される。
The cross-sectional shape of the paper tube is not particularly limited as long as it is a circular shape, a square shape, or another shape, as long as it is a cylindrical shape.
The paper used to form the paper tube is inorganic paper.
The inorganic paper is configured to contain 80% by weight or more of an inorganic material composed of inorganic fibers and inorganic powder, and includes, for example, pulp fibers and an organic binder as other components.
無機繊維としては、ガラス繊維や炭素繊維が例示できる。
無機粉体としては、ケイ酸マグネシウム、水酸化アルミニウム、炭酸カルシウムなどが例示出来る。無機粉体は、例えば無機材料全体の６０質量％以上９５質量％含有する。
本実施形態では、無機粉体としてケイ酸マグネシウムを使用する。ケイ酸マグネシウムはノンアスベストな天然鉱物であり、食品添加物などに使用されるため安全性を有する。
Examples of inorganic fibers include glass fibers and carbon fibers.
Examples of the inorganic powder include magnesium silicate, aluminum hydroxide, calcium carbonate and the like. The inorganic powder contains, for example, 60 mass% or more and 95 mass% of the entire inorganic material.
In this embodiment, magnesium silicate is used as the inorganic powder. Magnesium silicate is a non-asbestos natural mineral and has safety because it is used for food additives.
無機質紙の厚さは、例えば、０．２ｍｍ以上１ｍｍ以下の範囲とする。
本実施形態の紙管は、無機質紙から構成することで、火炎を貫通し難くい不燃性を有する。また、無機材料が耐熱保形性を有して、火事などで熱が加えられときに無機粉体の結晶がメタ化して緻密な構造になり、形状保持して火炎の貫通を抑制するようになる。
特に、無機質紙の無機材料の主成分をケイ酸マグネシウムとすることで、より確実に不燃性を有する紙管を提供可能となる。
The thickness of the inorganic paper is, for example, in the range of 0.2 mm to 1 mm.
The paper tube of the present embodiment is made of inorganic paper and has nonflammability that hardly penetrates the flame. In addition, the inorganic material has heat-resistant shape retention, and when heat is applied in a fire or the like, the crystal of the inorganic powder becomes meta and becomes a dense structure, and the shape is maintained to suppress the penetration of the flame. Become.
In particular, by using magnesium silicate as the main component of the inorganic material of the inorganic paper, it is possible to provide a paper tube having nonflammability more reliably.
ここで、居住、商業用施設、駅舎、空港等公共施設等の建築物において、火災時に燃え広がらないようにするために、一定の規模・用途に供する、居室や廊下・階段等の避難経路等は、その壁や天井の仕上げ材に、それぞれの要求性能に応じた防火材料（不燃材料、準不燃材料及び難燃材料）を用いなければならないことが、法律（施行令第１２９条）で義務付けられている。 Here, in buildings such as residences, commercial facilities, station buildings, airports, and other public facilities, evacuation routes such as living rooms, corridors, stairs, etc. are provided for a certain scale and use so that they do not spread during a fire. The law (Enforcement Ordinance Article 129) mandates that fireproof materials (non-combustible materials, semi-incombustible materials and flame-retardant materials) corresponding to the required performance must be used for the finishing materials of the walls and ceilings. It has been.
これに対し、上述のように本実施形態の紙管は不燃性を発揮することで、不燃を要求されるような箇所に適用でき且つ美観を損なわない。
ここで、積層する無機質紙間に、アルミニウム薄板などの金属板又はガラスペーパーを介挿させても良い。金属板やガラスペーパーは、筒状に巻き付ける変形できるだけの厚さの薄板とする。
On the other hand, as described above, the paper tube of the present embodiment exhibits nonflammability, so that it can be applied to places where nonflammability is required and the aesthetic appearance is not impaired.
Here, a metal plate such as an aluminum thin plate or glass paper may be interposed between the inorganic papers to be laminated. The metal plate or glass paper is a thin plate having a thickness that can be deformed and wound in a cylindrical shape.
金属板やガラスペーパーを介挿することで、紙管の剛性が向上出来ることから、無機質紙の積層数を押さえることが可能となる。
また、２枚の無機質紙間に金属板又はガラスペーパーを介挿した複合基材を、積層数が３層となるように芯材に巻き付けることで紙管を構成するようにしても良い。複合基材の積層数は２層でも構わないが。３層以上が好ましい。
By interposing a metal plate or glass paper, the rigidity of the paper tube can be improved, so that the number of laminated inorganic papers can be suppressed.
Further, a paper tube may be configured by winding a composite base material in which a metal plate or glass paper is interposed between two sheets of inorganic paper around a core material so that the number of layers is three. The number of laminated composite substrates may be two. Three or more layers are preferred.
本実施形態の紙管の使用例を図１及び図２に示す。図１は、紙管を長椅子の座面部分に適用した例であり、図２は、天井から吊って天井をデザインしたものである。勿論この例に限定されず、間仕切り壁を構成したり、テーブルの脚を構成したりしても良い。 An example of use of the paper tube of this embodiment is shown in FIGS. FIG. 1 is an example in which a paper tube is applied to a seat surface portion of a chaise longue, and FIG. 2 is a ceiling designed by hanging from a ceiling. Of course, the present invention is not limited to this example, and a partition wall or a table leg may be configured.
紙管の不燃性について、次の評価を実施した。
なお、評価は、無機質紙を重ねた平板状のサンプルで行った。
無機質紙としては、無機粉体であるケイ酸マグネシウムを８０質量％、無機繊維であるガラス繊維を５質量％、その他をパルプ繊維及び有機バインダからなる無機質紙を用意した。紙の厚さは０．２５ｍｍである。
The following evaluation was performed about the nonflammability of the paper tube.
In addition, evaluation was performed with the flat sample which piled up the inorganic paper.
As the inorganic paper, inorganic paper composed of 80% by mass of magnesium silicate which is an inorganic powder, 5% by mass of glass fiber which is an inorganic fiber, and the other composed of pulp fiber and an organic binder was prepared. The paper thickness is 0.25 mm.
そのような無機質紙を４枚重ねた実施例１のサンプルと、無機質紙を５枚重ねた実施例２のサンプルを用意した。
そして、実施例１及び実施例２としてそれぞれ３つのサンプルを用意して、不燃性の試験を行った。
不燃性試験は、ＩＳＯ５６６０−１に準拠し、建築基準法第二条第９号及び建築基準法施工令第１０８条の２に基づく防耐火試験方法と性能評価規格に従うコーンカロリーメーター試験機による発熱性試験を実施した。
A sample of Example 1 in which four sheets of such inorganic paper were stacked and a sample of Example 2 in which five sheets of inorganic paper were stacked were prepared.
And three samples were prepared as Example 1 and Example 2, respectively, and the nonflammability test was done.
The incombustibility test is based on ISO 5660-1, and the heat generated by the cone calorimeter tester according to the fire prevention test method and performance evaluation standard based on Article 9-2 of the Building Standards Act and Article 108-2 of the Building Standards Act Construction Order A sex test was performed.
そして、加熱開始後２０分間の総発熱量（ＭＪ／ｍ２）が、８ＭＪ／ｍ２以下であり、加熱開始後２０分間の最大発熱速度として、１０秒以上継続して２００ｋＷ／ｍ２を超えなければ、合格とした。但し、基材に亀裂や穴のないことも条件とした。
試験結果を表１に示す。
The gross calorific value of the heating starting after 20 min (MJ / m 2) is, and the 8 MJ / m 2 or less, the maximum heat release rate of the start of heating after 20 minutes, exceed 200 kW / m 2 to continue for 10 seconds or more If not, it was accepted. However, it was also a condition that the substrate had no cracks or holes.
The test results are shown in Table 1.
表１から分かるように、どのサンプルも上記試験基準を満足していることが分かる。
そして、このような不燃性試験をクリアした不燃材料で、紙管状に成型して使用すればよい。
ここで、無機質紙の積層を６〜９層まで変更して行ったところ、８層以上では、加熱開始後２０分間の総発熱量（ＭＪ／ｍ２）が、８ＭＪ／ｍ２を超えた。従って、無機質紙の積層数は７層以下が好ましい。
As can be seen from Table 1, it can be seen that all the samples satisfy the above test criteria.
And what is necessary is just to shape | mold and use for a paper tube with the nonflammable material which cleared such a nonflammability test.
Here, was conducted by changing the layered inorganic sheet to 6-9 layers, the eight layers or more, the total amount of heat generated by the heating start after 20 minutes (MJ / m 2) is exceeded 8 MJ / m 2. Therefore, the number of laminated inorganic papers is preferably 7 or less.
