Description
本発明は、不燃化処理剤及び不燃化処理方法に関する。 The present invention relates to an incombustible treatment agent and an incombustible treatment method.
従来より、織物などを不燃化する技術が開発されている。例えば、特許文献１には、植物系天然素材を炭化して優れた防火耐火断熱性能を持つ材料を提供する方法が開示されている。具体的には、株式会社ＪＥＲＩＣＯの防火薬剤ＡＲＴＥＸ（アルテックス）ＭＦの水溶液（濃度１２重量%）に、綿などの植物天然素材を十分含浸させたあと、２４時間自然乾燥するか７０℃で３時間の強制乾燥を行い、その後窒素ガス雰囲気下、電気炉中、２７０℃で１０分加熱することにより炭化する方法が開示されている。こうして得られた材料は、優れた防火耐火性能を有する。 Conventionally, a technique for making a textile fabric incombustible has been developed. For example, Patent Document 1 discloses a method for providing a material having excellent fire-proof and fire-proof heat insulation performance by carbonizing a plant-based natural material. Specifically, an aqueous solution (concentration: 12% by weight) of the fire prevention agent ARTEX (Artex) MF from JERICO Co., Ltd. is sufficiently impregnated with plant natural materials such as cotton, and then air-dried for 24 hours or 3 at 70 ° C. A method of carbonizing by performing forced drying for a period of time and then heating at 270 ° C. for 10 minutes in an electric furnace under a nitrogen gas atmosphere is disclosed. The material thus obtained has excellent fireproof and fireproof performance.
しかしながら、上述した方法で得られた材料は、色は元の色ではなく炭化によって黒色に変化し、肌さわりも元の感触とは異なるものになってしまうという問題があった。 However, the material obtained by the above-described method has a problem that the color changes to black instead of the original color due to carbonization, and the skin feel becomes different from the original touch.
本発明は、上述した課題に鑑みなされたものであり、織布又は不織布の色合いや手触りを損なうことなく不燃化することを主目的とする。 This invention is made | formed in view of the subject mentioned above, and makes it the main objective to make it nonflammable, without impairing the color and touch of a woven fabric or a nonwoven fabric.
本発明は、上述の主目的を達成するために以下の手段を採った。 The present invention adopts the following means in order to achieve the main object described above.
すなわち、本発明の不燃化処理剤は、水と、ポリリン酸アンモニウムと、硫酸アンモニウムと、高分子分散剤（polymeric dispersant）と、アンモニアとを含むものである。 That is, the incombustible treatment agent of the present invention contains water, ammonium polyphosphate, ammonium sulfate, a polymeric dispersant, and ammonia.
この不燃化処理剤によれば、織布又は不織布の色合いや手触りを損なうことなく不燃化することができる。例えば、織布又は不織布からなる処理対象物を、この不燃化処理剤に含浸させ、その後乾燥させれば、色合いや手触りを損なうことなく不燃化することができる。 According to this incombustible treatment agent, incombustibility can be achieved without impairing the color or touch of the woven or non-woven fabric. For example, if a processing object made of woven fabric or non-woven fabric is impregnated with this incombustible treatment agent and then dried, it can be incombustible without impairing color and touch.
本発明の不燃化処理剤において、高分子分散剤としては、ポリエーテル系分散剤が好ましく、塩基性基を有するポリエーテル系分散剤がより好ましく、アミノ基を有するポリエーテル系分散剤が更に好ましい。こうした高分子分散剤としては、ソルスパース２００００（日本ルーブリゾール株式会社製）、エチレングリコールモノフェニルエーテル（東洋インキ株式会社製）などが挙げられる。 In the incombustible treatment agent of the present invention, the polymer dispersant is preferably a polyether dispersant, more preferably a polyether dispersant having a basic group, and still more preferably a polyether dispersant having an amino group. . Examples of such a polymer dispersant include Solsperse 20000 (manufactured by Nippon Lubrizol Corporation), ethylene glycol monophenyl ether (manufactured by Toyo Ink Co., Ltd.), and the like.
本発明の不燃化処理剤において、高分子分散剤は、ポリリン酸アンモニウム２０質量部に対して１〜２．５質量部含まれていることが好ましい。高分子分散剤の含有量が下限値を下回ると、本発明の効果が十分得られないおそれがあるため好ましくない。また、高分子分散剤の含有量が上限値を上回ったとしても、効果上の差異はほとんどみられないため、経済的見地から好ましくない。 In the incombustible treatment agent of the present invention, the polymer dispersant is preferably contained in an amount of 1 to 2.5 parts by mass with respect to 20 parts by mass of ammonium polyphosphate. When the content of the polymer dispersant is lower than the lower limit, it is not preferable because the effect of the present invention may not be sufficiently obtained. Moreover, even if the content of the polymer dispersant exceeds the upper limit value, there is almost no difference in effect, which is not preferable from an economic standpoint.
本発明の不燃化処理剤において、アンモニアは、２５質量％のアンモニア水としてポリリン酸アンモニウム２０質量部に対して５〜１０質量部含まれていることが好ましい。アンモニアの含有量が下限値を下回ると、本発明の効果が十分得られないおそれがあるため好ましくない。また、アンモニアの含有量が上限値を上回ったとしても、効果上の差異はほとんどみられないため、経済的見地から好ましくない。 In the incombustible treatment agent of the present invention, it is preferable that 5 to 10 parts by mass of ammonia is contained as 25% by mass of ammonia water with respect to 20 parts by mass of ammonium polyphosphate. If the ammonia content is below the lower limit, the effects of the present invention may not be sufficiently obtained, which is not preferable. Further, even if the ammonia content exceeds the upper limit, there is almost no difference in effect, which is not preferable from an economic standpoint.
本発明の不燃化処理剤において、硫酸アンモニウムは、ポリリン酸アンモニウム２０質量部に対して１０〜４０質量部含まれていることが好ましく、２０〜３０質量部含まれていることがより好ましい。 In the incombustible treatment agent of the present invention, the ammonium sulfate is preferably contained in an amount of 10 to 40 parts by mass and more preferably 20 to 30 parts by mass with respect to 20 parts by mass of ammonium polyphosphate.
本発明の不燃化処理方法は、織布又は不織布からなる処理対象物を、上述した不燃化処理剤に含浸させ、その後乾燥させるものである。こうすれば、織布又は不織布の色合いや手触りを損なうことなく不燃化することができる。処理対象物は、不燃化処理剤を水で希釈した希釈液に含浸させることが好ましい。この希釈液の調製は、特に限定するものではないが、例えば、不燃化処理剤約５０質量部に対して全体が約５００質量部になるように水を加えて希釈してもよい。 The incombustible treatment method of the present invention involves impregnating a treatment object made of a woven fabric or a non-woven fabric with the above-described incombustible treatment agent and then drying it. If it carries out like this, it can be made incombustible, without impairing the color and touch of a woven fabric or a nonwoven fabric. The object to be treated is preferably impregnated with a dilute solution obtained by diluting an incombustible treatment agent with water. The preparation of the diluted solution is not particularly limited. For example, the diluted solution may be diluted by adding water so that the total amount is about 500 parts by mass with respect to about 50 parts by mass of the flame retardant.
本発明の不燃化処理方法において、処理対象物を不燃化処理剤に含浸させる時間は、その処理対象物の材質、使用量、厚さなどに応じて適宜設定すればよいが、概ね１０〜２００分である。また、含浸後の処理対象物の乾燥は自然乾燥でもよいし、熱風乾燥機などによる強制乾燥でもよい。 In the incombustible treatment method of the present invention, the time for impregnating the treatment object with the incombustible treatment agent may be appropriately set according to the material, amount of use, thickness, etc. of the treatment object, but is generally 10 to 200. Minutes. Moreover, the drying of the processing object after impregnation may be natural drying or forced drying by a hot air dryer or the like.
［実施例１〜５，比較例１，２］
ポリリン酸アンモニウムの粉末と、硫酸アンモニウムの粉末と、高分子分散剤であるソルスパース２００００（日本ルーブリゾール株式会社製）と、２５質量％アンモニア水とを、表１に示す質量（単位：ｇ）となるように秤量し、それらを混合することにより、不燃化処理剤を調製した。この不燃化処理剤を、表１に示す質量（単位：ｇ）の蒸留水で希釈し、得られた希釈液を用いて、表２に示す試料１〜４の不燃化処理を行った。不燃化処理は、各試料を約５００gの希釈液に常温で６０分間浸漬したあと、２４時間自然乾燥するか７０℃で３時間の強制乾燥することにより、実施した。不燃化処理後の各試料は、色合い、肌触りとも、不燃化処理前と比べてほとんど同じであった。
[Examples 1 to 5, Comparative Examples 1 and 2]
Ammonium polyphosphate powder, ammonium sulfate powder, Solsperse 20000 (manufactured by Nippon Lubrizol Co., Ltd.), which is a polymer dispersing agent, and 25% by mass ammonia water have the mass (unit: g) shown in Table 1. Incombustible treatment agents were prepared by weighing them and mixing them. This incombustible treating agent was diluted with distilled water having a mass (unit: g) shown in Table 1, and samples 1 to 4 shown in Table 2 were subjected to incombustible treatment using the obtained diluent. The incombustibility treatment was carried out by immersing each sample in a diluted solution of about 500 g for 60 minutes at room temperature, followed by natural drying for 24 hours or forced drying at 70 ° C. for 3 hours. Each sample after the incombustible treatment was almost the same in terms of color and touch as compared to before the incombustible treatment.
次に、不燃化の評価を行った。具体的には、不燃化処理後の各試料（表２参照）を金網に固定し、試料に向けて高カロリー１３００℃ガスバーナーにより火炎を３０秒間噴射した。試料からガスバーナー口までの距離は約９０ｍｍとした。その結果を表２に示す。表２に示すように、比較例１，２では、試料１〜４のすべてにおいて着火し、燃焼して消失した。一方、実施例１〜４では、試料１〜４のすべてにおいて炭化して黒色に変化したものの、着火せず形状が保持された。 Next, incombustibility was evaluated. Specifically, each sample after the incombustibility treatment (see Table 2) was fixed to a wire mesh, and a flame was injected toward the sample with a high-calorie 1300 ° C. gas burner for 30 seconds. The distance from the sample to the gas burner port was about 90 mm. The results are shown in Table 2. As shown in Table 2, in Comparative Examples 1 and 2, all the samples 1 to 4 were ignited, burned and disappeared. On the other hand, in Examples 1 to 4, although all of Samples 1 to 4 were carbonized and changed to black, the shape was maintained without ignition.
また、アルミニウム板に向けて同様にしてガスバーナーにより火炎を噴射したところ、火炎の当たっている部分は溶融して６０秒後に穴が開いた。これに対して、実施例１の希釈液で不燃化処理した試料３でアルミニウム板を覆い、試料３に向けてガスバーナーにより火炎を噴射したところ、試料３は炭化して黒色に変化したものの着火せず、試料３に覆われているアルミニウム板に変化はみられなかった。更に、ガラス板に向けて同様にしてガスバーナーにより火炎を噴射したところ、火炎の当たっている部分は溶融して破損した。これに対して、実施例１の希釈液で不燃化処理した試料３でガラス板を覆い、試料３に向けてガスバーナーにより火炎を噴射したところ、試料３は炭化して黒色に変化したものの着火せず、試料３に覆われているガラス板に変化はみられなかった。こうしたことから、不燃化処理後の処理対象物である試料３は、熱を伝えにくくする効果すなわち断熱効果も有している。 Similarly, when a flame was sprayed toward the aluminum plate by a gas burner, the portion hit by the flame melted and a hole was opened 60 seconds later. On the other hand, when the aluminum plate was covered with the sample 3 incombustible treated with the diluent of Example 1 and a flame was injected toward the sample 3 with a gas burner, the sample 3 was carbonized and turned black. No change was observed in the aluminum plate covered with Sample 3. Further, when a flame was sprayed toward the glass plate by a gas burner in the same manner, the portion hit by the flame was melted and damaged. On the other hand, when the glass plate was covered with the sample 3 incombustible treated with the diluent of Example 1 and a flame was injected toward the sample 3 with a gas burner, the sample 3 was carbonized and turned black. No change was observed in the glass plate covered with Sample 3. For these reasons, the sample 3 that is the object to be treated after the incombustibility treatment also has an effect of making it difficult to transfer heat, that is, a heat insulation effect.
本発明は、織布又は不織布を不燃化する際に利用可能である。 The present invention can be used when making a woven fabric or a non-woven fabric incombustible.
