本発明は、ＶＯＣ対策材のアルデヒド吸着活性を判定するための判定用組成物、及びＶＯＣ対策材のアルデヒド吸着活性を判定する方法に関する。 The present invention relates to a determination composition for determining the aldehyde adsorption activity of a VOC countermeasure material and a method for determining the aldehyde adsorption activity of a VOC countermeasure material.
自動車の車室内で使用される木質ボード、ウレタンモールド等の各種基材は、ＶＯＣ（Ｖｏｌａｔｉｌｅ Ｏｒｇａｎｉｃ Ｃｏｍｐｏｕｎｄｓ）１３物質の一種であるアセトアルデヒド、ホルムアルデヒド等を発生させることがある。これらの化学物質は、シックハウス症候群のもっとも大きな原因とされており、自動車等の内装材においても、ＶＯＣを低減する動きとして（社）自動車工学会によるＶＯＣ排出抑制の自主的取り組みが始まっている。その取り組みの一つとして、アルデヒドキャッチャー剤をクッションパッド等に塗布することが行われている（例えば、特許文献１を参照。）。 Various base materials such as wood boards and urethane molds used in the interior of an automobile may generate acetaldehyde, formaldehyde, which is a kind of VOC (Volatile Organic Compounds) 13 material. These chemical substances are considered to be the largest cause of sick house syndrome, and voluntary efforts to suppress VOC emissions by the Japan Society for Automotive Engineers have begun as a movement to reduce VOC in interior materials such as automobiles. As one of the efforts, an aldehyde catcher agent is applied to a cushion pad or the like (see, for example, Patent Document 1).
しかし、アルデヒドキャッチャー剤を上記基材に付着させてＶＯＣ対策材とし、これを自動車メーカーに納入する際、当該アルデヒドキャッチャー剤が効果を発現し、ＶＯＣを吸着するか否かを確認することはこれまで実質的に行われていなかった。また、輸送工程や納入先の作業環境下で、ＶＯＣ対策材が実際にＶＯＣ吸着活性を有するか否かを容易に確認する方法がなかった。 However, when an aldehyde catcher agent is attached to the base material as a VOC countermeasure material and delivered to an automobile manufacturer, it is necessary to confirm whether the aldehyde catcher agent is effective and adsorbs VOC. Until practically not done. In addition, there is no method for easily confirming whether or not the VOC countermeasure material actually has VOC adsorption activity under the transportation process or the work environment of the delivery destination.
そこで、本発明は、ＶＯＣ対策材のアルデヒド吸着活性を容易に判定することを可能にする組成物を提供することを目的とする。また、本発明は、ＶＯＣ対策材のアルデヒド吸着活性を容易に判定することが可能な方法を提供することを目的とする。さらに、本発明は、アルデヒド吸着活性を判定することを含む、ＶＯＣ対策材の製造方法を提供することも目的とする。 Then, an object of this invention is to provide the composition which makes it possible to determine easily the aldehyde adsorption | suction activity of a VOC countermeasure material. Another object of the present invention is to provide a method capable of easily determining the aldehyde adsorption activity of a VOC countermeasure material.

Furthermore, since the amount of dyeing increases in proportion to the above activity, it is possible to efficiently manage the amount of aldehyde catcher agent attached and the presence or absence of activity.

Below, the method to determine the aldehyde adsorption activity of the VOC countermeasure material to which the aldehyde catcher agent has adhered and the method for producing the VOC countermeasure material including determining the aldehyde adsorption activity by the method will be described.
本実施形態に係るＶＯＣ対策材のアルデヒド吸着活性を判定する方法は、ＶＯＣ対策材に上記実施形態に係る組成物を接触させる工程と、ＶＯＣ対策材の染着の有無又は染着量を確認する工程とをこの順に備える。 The method for determining the aldehyde adsorption activity of the VOC countermeasure material according to the present embodiment includes the step of bringing the composition according to the above embodiment into contact with the VOC countermeasure material, and the presence or absence or the amount of dyeing of the VOC countermeasure material. Steps are provided in this order.
ＶＯＣ対策材は、基材にアルデヒドキャッチャー剤を付着させて製造することができる。 The VOC countermeasure material can be manufactured by attaching an aldehyde catcher agent to a base material.
アルデヒドキャッチャー剤は、主にアセトアルデヒドやホルムアルデヒド等のアルデヒド分子をキャッチすることができるアルデヒド吸着物質を含有する。アルデヒド吸着物質は、例えばアミノ基を有する。アミノ基を有するアルデヒド吸着物質によるアルデヒド分子の吸着機構は以下の反応式に示されるとおりである。
アミノ基を有するアルデヒド吸着物質の場合、アルデヒド吸着物質のアミノ基と、染料のスルホン酸基がイオン結合し、染料が不溶性の物質に変化することで基材の表層に固定され、その結果、基材への染着量がより増大するものと考えられる。 In the case of an aldehyde adsorbing substance having an amino group, the amino group of the aldehyde adsorbing substance and the sulfonic acid group of the dye are ion-bonded, and the dye is changed to an insoluble substance, so that it is fixed to the surface layer of the substrate. It is considered that the amount of dyeing to the material is further increased.
アミノ基を有するアルデヒド吸着物質を含有するアルデヒドキャッチャー剤としては、例えば、シリカ粒子等の多孔性物質と、当該多孔性物質の表面上に設けられたアミノ基とを有するものが挙げられる。また、アミノ基を有するアルデヒド吸着物質を含有するアルデヒドキャッチャー剤としては、キラクルＡＬ−０７（日華化学（株）製、商品名）、及びリケンレジン ＦＣ−１００（三木理研工業（株）製、商品名）等の市販品を挙げることができる。 Examples of the aldehyde catcher agent containing an aldehyde adsorbing substance having an amino group include those having a porous substance such as silica particles and an amino group provided on the surface of the porous substance. Moreover, as an aldehyde catcher agent containing an aldehyde-adsorbing substance having an amino group, Kiracle AL-07 (manufactured by Nikka Chemical Co., Ltd., trade name) and Riken Resin FC-100 (manufactured by Miki Riken Kogyo Co., Ltd. Name) etc. can be mentioned.
ＶＯＣ対策材に用いられる基材は、特に限定されるものではないが、自動車用内装材に用いられる基材であることが好ましい。基材は、例えば、樹脂部材、木質部材及び不織布からなる群から選ばれる少なくとも１種であってもよい。このような基材の具体例としては、ボランスＰＥＴ３層不織布（東洋紡（株）製、商品名）が挙げられる。 Although the base material used for a VOC countermeasure material is not specifically limited, It is preferable that it is a base material used for the interior material for motor vehicles. The substrate may be at least one selected from the group consisting of a resin member, a wood member, and a nonwoven fabric, for example. A specific example of such a substrate is Borans PET 3-layer nonwoven fabric (trade name, manufactured by Toyobo Co., Ltd.).
基材の大きさ、厚み、寸法等は特に限定されない。また基材には、目的に応じて当該分野で一般に利用される各種添加剤が付与又は含有されていてもよい。 The magnitude | size, thickness, dimension, etc. of a base material are not specifically limited. Moreover, the various additives generally utilized in the said field | area may be provided or contained in the base material according to the objective.
アルデヒドキャッチャー剤を基材へ付着させる方法としては、例えば特許文献１に記載されているように公知の手法を用いることができる。 As a method for attaching the aldehyde catcher agent to the substrate, a known method can be used as described in Patent Document 1, for example.
ＶＯＣ対策材に判定用組成物を接触させる工程には、当該技術分野において通常使用される染色手法が採用され得る。例えば、判定用組成物をＶＯＣ対策材に対して滴下してもよい。接触させる組成物の使用量は、当該技術分野において通常用いられる量であれば必ずしも限定されず適宜変更が可能である。なお、その後のＶＯＣ対策材の染着の有無又は染着量を確認する工程における正確性の観点から、組成物の基材への接触の後は、必要に応じ当業者に周知の手段を用いて水洗を行うことが好ましい。 In the step of bringing the determination composition into contact with the VOC countermeasure material, a dyeing technique usually used in the technical field can be employed. For example, the composition for determination may be dropped on the VOC countermeasure material. The amount of the composition to be contacted is not necessarily limited as long as it is an amount usually used in the technical field, and can be appropriately changed. From the viewpoint of accuracy in the subsequent step of confirming the presence or absence of dyeing of the VOC countermeasure material or the amount of dyeing, after the contact of the composition with the base material, means well known to those skilled in the art are used as necessary. It is preferable to perform washing with water.
ＶＯＣ対策材の染着の有無又は染着量を確認する方法としては、目視による確認方法や、染着量の指標となるＫ／Ｓ値を測定する方法等が挙げられる。ここで、Ｋ／Ｓ値とは、次式で定義される表面色濃度の指数であり、Ｋ／Ｓ値は、値が高いほど色濃度は高くなり、値が低いほど色濃度は低くなる。Ｋ／Ｓ値等を指標として染着量を定量的に評価することで、アルデヒド吸着物質の吸着量又は吸着活性を定量的に判定することが可能である。Ｋ／Ｓ値は、当該技術分野において通常用いられる測定装置を用いて、測定することができる。
（Ｋ：光の吸収係数、Ｓ：光の散乱係数、Ｒ：表面反射率）
Examples of the method for confirming the presence or absence or the amount of dyeing of the VOC countermeasure material include a visual confirmation method and a method for measuring a K / S value that serves as an index of the amount of dyeing. Here, the K / S value is an index of the surface color density defined by the following equation. The higher the value of the K / S value, the higher the color density, and the lower the value, the lower the color density. By quantitatively evaluating the dyeing amount using the K / S value or the like as an index, it is possible to quantitatively determine the adsorption amount or adsorption activity of the aldehyde adsorbing substance. The K / S value can be measured using a measuring apparatus that is usually used in the art.
(K: light absorption coefficient, S: light scattering coefficient, R: surface reflectance)
上記方法によりアルデヒド吸着活性を判定した後、ＶＯＣ対策材を自動車内装材等の各用途に使用することができる。 After determining the aldehyde adsorption activity by the above method, the VOC countermeasure material can be used for each application such as an automobile interior material.
以下、実施例を挙げて本発明についてさらに具体的に説明する。ただし、本発明はこれら実施例に限定されるものではない。 Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to these examples.
ＶＯＣ対策材の原料となる基材として、ボランスＰＥＴ３層不織布（東洋紡（株）製）又はＰＥＴトロピカル織布（オージー長瀬カラーケミカル（株）製）を使用した。アルデヒドキャッチャー剤としては、以下のものを用いた。
キラクル（ｋｉｒａｋｕｌｕ）ＡＬ−０７（日華化学（株）製）：表面にアミノ基を有するアルデヒド吸着物質
リケンレジン ＦＣ−１００（三木理研工業（株）製）：末端にアミノ基を有する有機物の複合体
As a base material used as a raw material for the VOC countermeasure material, Borans PET three-layer nonwoven fabric (manufactured by Toyobo Co., Ltd.) or PET tropical woven fabric (manufactured by Aussie Nagase Color Chemical Co., Ltd.) was used. The following were used as the aldehyde catcher agent.
Kirakulu AL-07 (manufactured by Nikka Chemical Co., Ltd.): Aldehyde adsorbent having an amino group on the surface, Riken Resin FC-100 (manufactured by Miki Riken Kogyo Co., Ltd.): Complex of organic substance having an amino group at the terminal
＜キラクルＡＬ−０７をアルデヒドキャッチャー剤として用いたＶＯＣ対策材の判定試験＞
（実施例１）
キラクルＡＬ−０７を０．５ｇ／ｍ２でボランス不織布（１０ｃｍ×１０ｃｍ）に塗布して、ＶＯＣ対策材を準備した。このＶＯＣ対策材に対して、判定用組成物として濃度５ｇ／ＬのＣＩ Ｄｉｒｅｃｔ Ｂｌｕｅ ８６（Ｋａｙａｒｕｓ Ｔｕｒｑｕｏｉｓｅ Ｂｌｕｅ ＧＬ、日本化薬（株）製）水溶液を２ｍＬ滴下後、常温で３分間放置した。その後、ＶＯＣ対策材を水洗すると、きわめて鮮明なブルー色が残った。
<Determination test of VOC countermeasure material using Kirakuru AL-07 as aldehyde catcher agent>
Example 1
Kirakuru AL-07 was applied to Borans nonwoven fabric (10 cm × 10 cm) at 0.5 g / m 2 to prepare a VOC countermeasure material. To this VOC countermeasure material, 2 mL of a CI Direct Blue 86 (Kayarus Turquoise Blue GL, manufactured by Nippon Kayaku Co., Ltd.) aqueous solution having a concentration of 5 g / L was dropped as a composition for determination and allowed to stand at room temperature for 3 minutes. Thereafter, when the VOC countermeasure material was washed with water, a very clear blue color remained.
これは、アルデヒドキャッチャー剤におけるアルデヒド吸着物質のアミノ基と染料のスルホン酸基との反応物が不織布繊維の表層に固定化したためと考えられる。この結果から、ＶＯＣ対策材が、アルデヒドキャッチャー剤によるアルデヒド吸着活性を有すると判定できた。 This is considered to be because the reaction product of the amino group of the aldehyde adsorbing substance and the sulfonic acid group of the dye in the aldehyde catcher agent was immobilized on the surface layer of the nonwoven fabric fiber. From this result, it could be determined that the VOC countermeasure material has aldehyde adsorption activity by the aldehyde catcher agent.

<Relationship test between application amount and dyeing concentration of Kirakuru AL-07>
(Example 7)
In Bolans nonwoven (10cm × 10cm), respectively Kirakuru AL-07, 0g / m 2 , 0.01g / m 2, 0.05g / m 2, 0.10g / m 2, 0.50g / m 2, 2 .00g / m 2, and was applied at a coverage of 4.00 g / m 2, was prepared VOC measures material. 2 mL of a 5 g / L CI Direct Blue 86 aqueous solution (composition for determination) was dropped on each VOC countermeasure material, and left at room temperature for 3 minutes. Thereafter, each VOC countermeasure material was washed with water, and the K / S value of the colored portion was measured.
アルデヒドキャッチャー剤の塗布量とＫ／Ｓ値の関係を図１に示す。図１の結果から、アルデヒドキャッチャー剤の塗布量に比例してＫ／Ｓ値が上昇することが確認され、アルデヒドキャッチャー剤の塗布量を定量的に測定することが可能であることがわかった。 The relationship between the application amount of the aldehyde catcher agent and the K / S value is shown in FIG. From the result of FIG. 1, it was confirmed that the K / S value increased in proportion to the application amount of the aldehyde catcher agent, and it was found that the application amount of the aldehyde catcher agent can be quantitatively measured.
＜アルデヒドキャッチャー剤未処理の基材を用いた比較試験＞
（比較例１）
アルデヒドキャッチャー剤処理を施していない不織布に対し、実施例１及び２において用いた各染料を滴下し、実施例１と同様の方法によって試験した結果、染料の固着は全く見られず、不織布の呈色も確認できなかった。
<Comparative test using non-treated aldehyde catcher agent>
(Comparative Example 1)
Each of the dyes used in Examples 1 and 2 was dropped on the nonwoven fabric that had not been treated with the aldehyde catcher agent, and tested in the same manner as in Example 1. The color could not be confirmed.
＜スルホン酸基の有無に関する比較試験＞
キラクルＡＬ−０７を２ｇ／ｍ２でＰＥＴトロピカル織布に塗布して、ＶＯＣ対策材を準備した。このＶＯＣ対策材に対して、判定用組成物として濃度５ｇ／ＬのＣＩ Ｄｉｒｅｃｔ Ｂｌｕｅ ８６水溶液及びスルホン酸基を有しない染料を含有する組成物として濃度５ｇ／ＬのＣＩ Ｂａｓｉｃ Ｂｌｕｅ ４１（Ｋａｙａｃｙｌ Ｂｌｕｅ ＧＲＬ、分子量約４１９、日本化薬（株）製、化学構造を以下に示す。）水溶液をそれぞれ０．５ｍＬずつ滴下後、常温で５分間放置した。その後、ＶＯＣ対策材を水洗すると、ＣＩ Ｄｉｒｅｃｔ Ｂｌｕｅ ８６についてはきわめて鮮明なブルー色が残ったのに対し、ＣＩ Ｂａｓｉｃ Ｂｌｕｅ ４１については染料の固着は全く見られず、基材の呈色も確認できなかった。図２に、それぞれの染料を塗布した場合の水洗前の基材の呈色を、図３に、水洗後の基材の呈色をそれぞれ示す。
<Comparative test on the presence or absence of sulfonic acid groups>
Kirakuru AL-07 was applied to a PET tropical woven fabric at 2 g / m 2 to prepare a VOC countermeasure material. For this VOC countermeasure material, a CI Direct Blue 86 aqueous solution having a concentration of 5 g / L as a composition for determination and a CI Basic Blue 41 (Kayacyl Blue GRL) having a concentration of 5 g / L as a composition containing a dye having no sulfonic acid group. The molecular weight was about 419, manufactured by Nippon Kayaku Co., Ltd., and the chemical structure is shown below. Thereafter, when the VOC countermeasure material was washed with water, an extremely clear blue color remained for CI Direct Blue 86, whereas no dye fixation was observed for CI Basic Blue 41, and the coloration of the substrate could be confirmed. There wasn't. FIG. 2 shows the coloring of the base material before washing with water when each dye is applied, and FIG. 3 shows the coloring of the base material after washing with water.
