The present invention relates to a product that has been subjected to flame retardant or non-flammable treatment.
Flame retardant or non-flammable objects are raw materials such as natural fiber, synthetic fiber, chemical fiber, synthetic paper, wood, bamboo, etc. and products manufactured from these raw materials, such as carpets, rugs, flooring, wall materials, etc. , Fiber products such as ceiling products such as ceiling materials, or synthetic resin products, or continuous foamed soft and semi-rigid urethane foam, polyester nonwoven fabric, and urethane foam that is under felt of carpet, etc. Can be considered.
In the present specification, “flame retardant treatment” means a level that ignites when a flame is applied, but self-extinguishes and carbonizes as soon as the flame is released, and “incombustible treatment” means that no flame is ignited.
化学繊維や合成繊維を使用した織地、編地又は不織布等を難燃化させる薬剤は従来より各種提案されている。
臭素系及び塩素系の難燃剤は高温によりそれぞれ臭素系の有害ガス及び塩化水素系の有害ガスが発生し、ダイオキシン類が発生する問題がある。
また、これら薬剤は、不燃化という点からはその効果は不十分なものである。
Various agents have been proposed in the past to make flame-retardant fabrics, knitted fabrics or nonwoven fabrics using chemical fibers or synthetic fibers.
Bromine-based and chlorine-based flame retardants have a problem in that bromine-based and hydrogen chloride-based gases are generated at high temperatures, and dioxins are generated.
In addition, these drugs are insufficient in effect from the point of incombustibility.
また、有害ガスが発生しない難燃化及び不燃化剤として、下記特許文献１に示されるポリホウ酸ナトリウム水溶液（株式会社トラストライフ製、商品名「ファイアレスＢ」）、又は下記特許文献２に示されるポリケイ酸ナトリウム水溶液（株式会社トラストライフ製、商品名「ファイアレスＳ」）が知られており、これらの難燃化及び不燃化剤は、火炎との接触により発泡化することで難燃又は不燃効果を有している。
これらの難燃化及び不燃化剤は、ポリエステル系、ナイロン系、ポリプロピレン系等の化学繊維製品、合成繊維製品及びこれらの樹脂を使用した樹脂フィルム、ウレタンフォーム、発泡スチロール等の発泡樹脂体、樹脂成分を含有する合成紙等に対して適用しやすくしたものである。
しかし、このポリホウ酸ナトリウム水溶液又はポリケイ酸ナトリウム水溶液は、親水性に劣る被処理製品に付着しにくい場合があった。
Further, as a flame retardant and incombustible agent that does not generate harmful gas, an aqueous sodium polyborate solution (trade name “Fireless B” manufactured by Trust Life Co., Ltd.) shown in the following Patent Document 1 or shown in Patent Document 2 below. A sodium polysilicate aqueous solution (trade name “Fireless S”, manufactured by Trust Life Co., Ltd.) is known, and these flame retardants and flame retardants are flame retardant or foamed by contact with a flame. Has non-flammable effect.
These flame retardants and flame retardants are polyester, nylon, polypropylene, and other chemical fiber products, synthetic fiber products, resin films using these resins, urethane foam, foamed resin bodies such as expanded polystyrene, and resin components. This makes it easier to apply to synthetic papers containing
However, this sodium polyborate aqueous solution or sodium polysilicate aqueous solution may be difficult to adhere to a product to be treated having poor hydrophilicity.
本発明は、親水性の弱い素材にも容易に難燃化又は不燃化処理できる方法及び、そのような処理をした部材の提供を目的とする。 An object of the present invention is to provide a method capable of easily making a flame-retardant or non-flammable treatment even for a weakly hydrophilic material and a member subjected to such a treatment.
本発明に係る難燃化又は不燃化処理部材は、親水性ポリマーの水分散液と、ポリホウ酸ナトリウム水溶液、又はポリケイ酸ナトリウム水溶液とを混合した処理液を作成し、前記処理液に浸漬及び乾燥するか、あるいは前記処理液を塗布及び乾燥させたことを特徴とする。 The flame retardant or non-flammable treatment member according to the present invention is a treatment solution prepared by mixing an aqueous dispersion of a hydrophilic polymer with a sodium polyborate aqueous solution or a sodium polysilicate aqueous solution, immersed in the treatment solution and dried. Alternatively, the treatment liquid is applied and dried.
ここで、親水性ポリマーは被処理素材に親水性を付与するものであれば特に限定されないが、親水性ポリマーの水分散液は、ポリエステル樹脂を主成分とするエマルション液であってもよい。 Here, the hydrophilic polymer is not particularly limited as long as it imparts hydrophilicity to the material to be treated, but the aqueous dispersion of the hydrophilic polymer may be an emulsion liquid mainly composed of a polyester resin.
なお、難燃化又は不燃化処理の対象物は、そのままでは燃え易いものを対象とするものであり、例えば繊維糸又は繊維構造体、樹脂フィルム、発泡樹脂体、樹脂との合成紙、木材、竹材等が考えられ、繊維は天然繊維、合成繊維、化学繊維等をいい、化学繊維としては具体的にはポリエステル系繊維、ナイロン系繊維、ポリプロピレン系繊維等をいう。
合成繊維としては、綿とポリエステルの混紡等の天然繊維との混紡も含まれる。
繊維構造体としては、上記繊維を使用した生地や製品であり、織地、編地又は不織布等の生地化手段及び製品化手段を問わない。
樹脂フィルムとしては、例えば、ポリエステルフィルム、ポリプロピレンフィルム、ナイロンフィルム等を挙げることができ、発泡樹脂体としては発泡ウレタンフォーム、発泡スチロール等がある。
In addition, the flame retardant or non-flammable target is intended to be easily flammable as it is, for example, fiber yarn or fiber structure, resin film, foamed resin body, synthetic paper with resin, wood, Bamboo and the like are conceivable, and the fibers are natural fibers, synthetic fibers, chemical fibers, and the like. Specifically, the chemical fibers are polyester fibers, nylon fibers, polypropylene fibers, and the like.
Synthetic fibers also include blends of natural fibers such as cotton and polyester blends.
The fiber structure is a fabric or product using the above-described fibers, and any fabricizing means such as a woven fabric, a knitted fabric, or a non-woven fabric, and any productizing means may be used.
Examples of the resin film include a polyester film, a polypropylene film, and a nylon film. Examples of the foamed resin body include a foamed urethane foam and a polystyrene foam.
本発明は、親水性ポリマーが強く付着しやすい素材に効果的であり、親水性ポリマーがポリエステル樹脂を主成分とするエマルションである場合には、ポリエステル系繊維又はウレタンフォーム素材に効果的である。 The present invention is effective for a material to which a hydrophilic polymer is strongly and easily adhered, and is effective for a polyester fiber or a urethane foam material when the hydrophilic polymer is an emulsion mainly composed of a polyester resin.
また、難燃化又は不燃化処理部材にアルミ箔を積層すると、火炎による局部加熱に対するウレタンフォーム等の変形を防止することができる。
アルミ箔は積層できるレベルであれば厚みは特に限定されないが、取り扱いやすい点からは１０μｍ〜３０μｍ程度の厚みが好ましい。
アルミ箔は用途により難燃化又は不燃化処理対象物の必要な面に積層すればよく、平板状のものであれば片面又は両面に積層してもよい。
難燃化又は不燃化処理物の表面にアルミ箔を積層したものは不燃材料としてのみならず、軽量化材、防音材、断熱材としても使用できる。
特に不燃化処理物のベース材として発泡ウレタンフォームを使用すると、熱伝導率０．０２Ｗ／ｍＫで、従来のグラスウールの熱伝導率０．０４Ｗ／ｍＫの半分となり、断熱性及び環境性に優れる。
なお、難燃化又は不燃化処理の対象物に対して、処理剤塗布面に金属板、例えば厚みが０．３ｍｍ以上のアルミ板や綱板を積層する方法を採用してもよい。
Moreover, when an aluminum foil is laminated on the flame-retardant or non-combustible member, it is possible to prevent deformation of the urethane foam or the like due to local heating due to the flame.
The thickness of the aluminum foil is not particularly limited as long as it can be laminated, but a thickness of about 10 μm to 30 μm is preferable from the viewpoint of easy handling.
The aluminum foil may be laminated on the necessary surface of the flame retardant or incombustible treatment object depending on the use, and may be laminated on one side or both sides if it is a flat plate.
What laminated | stacked aluminum foil on the surface of a flame-retardant or incombustible processed material can be used not only as a non-combustible material but as a weight reducing material, a soundproof material, and a heat insulating material.
In particular, when foamed urethane foam is used as the base material of the incombustible material, the thermal conductivity is 0.02 W / mK, which is half the thermal conductivity of conventional glass wool, 0.04 W / mK, and is excellent in heat insulation and environmental properties.
In addition, you may employ | adopt the method of laminating | stacking a metal plate, for example, an aluminum board and a steel board with a thickness of 0.3 mm or more, on the processing agent application surface with respect to the target of a flame-retardant or incombustible process.
さらに、アルミ箔積層面に不燃化処理を施した面部材を積層する方法を採用してもよい。
不燃化処理物の表面にアルミ箔を積層した場合には、そのままでは内装及び外装の建材として使用するには美観上の問題がある。
アルミ箔積層面に不燃化処理を施した面部材、即ち建築用の意匠建材として使用されるもの、例えば杉材等の木製単板、割竹や網竹のような竹製単板、あるいは竹や繊維を編んだ網代等を重ね合せて積層すると、この問題が解決される。
なお、前記の単板や網代も本発明に係る難燃化又は不燃化処理を施してあるのが好ましい。
Furthermore, you may employ | adopt the method of laminating | stacking the surface member which gave the incombustible process to the aluminum foil lamination surface.
When the aluminum foil is laminated on the surface of the incombustible material, there is an aesthetic problem to use as it is as a building material for interior and exterior.
Non-combustible surface member made of aluminum foil laminated surface, that is, used as a design building material for construction, such as wooden veneer such as cedar, bamboo veneer such as split bamboo or net bamboo, or bamboo If the nets made of knitted fabrics or nets are laid on top of each other, this problem is solved.
In addition, it is preferable that the above-mentioned veneer and net are also subjected to the flame retardant or incombustible treatment according to the present invention.

なお、火炎により安定した発泡層を形成するには、これらは重合体として１０〜５０ｇ／ｍ２以上の付着量とすることが望ましく、付着量は多い方が難燃化及び不燃化の効果が高いが、最大付着量は対象物の物性により定まる。
また、着火しても火炎を遠ざけると自己消火する難燃化レベルでよい場合には、５〜１０ｇ／ｍ２程度の付着量でよい。
