2. The aldehyde deodorant composition according to 1, wherein the amount of the ammonium salt is 1 to 43 parts by mass and the amount of urea is 1 to 33 parts by mass when the total composition is 100 parts by mass.
3. The aldehyde deodorizing composition according to 1 or 2, wherein the ammonium salt is at least one selected from monoammonium phosphate, diammonium phosphate, and ammonium sulfate.
4). The aldehyde deodorizing composition according to any one of 1 to 3, comprising 45 to 97 parts by mass of water and 0 to 15 parts by mass of a binder resin, when the total composition is 100 parts by mass.
Aldehyde deodorant hardened | cured material obtained by drying the aldehyde deodorant composition of 5.4.
6. A gypsum board obtained by blending the aldehyde deodorant composition according to any one of 1 to 3.
本発明によれば、ホルムアルデヒドに対してはもちろんのことアセトアルデヒドに対しても高い消臭性を示し、また、安全性の高いアルデヒド消臭性組成物を提供できる。
また、本発明のアルデヒド消臭性組成物の成分であるアンモニウム塩と尿素は、共に良水溶性であり安全性が高いため、本発明のアルデヒド消臭性組成物は取り扱いが極めて容易である。
According to the present invention, it is possible to provide a highly safe aldehyde deodorizing composition that exhibits high deodorizing properties not only to formaldehyde but also to acetaldehyde.
In addition, since the ammonium salt and urea, which are components of the aldehyde deodorant composition of the present invention, are both highly water-soluble and highly safe, the aldehyde deodorant composition of the present invention is extremely easy to handle.
本発明のアルデヒド消臭性組成物は、アンモニウム塩及び尿素を含むことを特徴とする。
アンモニウム塩としては、無機酸又は有機酸のアンモニウム塩が使用可能である。
無機酸のアンモニウム塩としては、りん酸１アンモニウム、りん酸２アンモニウム、塩化アンモニウム、硫酸アンモニウム、クエン酸アンモニウム、塩化アンモニウム、亜硫酸アンモニウム、重亜硫酸アンモニウム、硝酸アンモニウム、フッ化アンモニウム、硫化アンモニウム、炭酸アンモニウム、炭酸水素アンモニウム等が挙げられる。
The aldehyde deodorant composition of the present invention is characterized by containing an ammonium salt and urea.
As the ammonium salt, an inorganic acid or an organic acid ammonium salt can be used.
Ammonium salts of inorganic acids include: 1 ammonium phosphate, 2 ammonium phosphate, ammonium chloride, ammonium sulfate, ammonium citrate, ammonium chloride, ammonium sulfite, ammonium bisulfite, ammonium nitrate, ammonium fluoride, ammonium sulfide, ammonium carbonate, carbonic acid Examples include ammonium hydrogen.
有機酸のアンモニウム塩としては、酢酸アンモニウム、蟻酸アンモニウム、プロピオン酸アンモニウム、シュウ酸アンモニウム、アクリル酸アンモニウム、ステアリン酸アンモニウム、アジピン酸アンモニウム、安息香酸アンモニウム、クエン酸アンモニウム等が使用できる。 Examples of the organic acid ammonium salt include ammonium acetate, ammonium formate, ammonium propionate, ammonium oxalate, ammonium acrylate, ammonium stearate, ammonium adipate, ammonium benzoate, and ammonium citrate.
本発明においては、無機酸のアンモニウム塩が、価格、水溶解性等から好適に使用される。そのなかでも、硫酸アンモニウム、りん酸１アンモニウム又はりん酸２アンモニウムが、水への溶解性や乾燥時の熱安定性から特に望ましく使用できる。 In the present invention, an ammonium salt of an inorganic acid is preferably used from the viewpoint of cost, water solubility and the like. Among them, ammonium sulfate, monoammonium phosphate, or diammonium phosphate can be particularly preferably used from the viewpoint of solubility in water and thermal stability during drying.

バインダー樹脂としては、ウレタン系樹脂、アクリル系樹脂又はこれらの共重合体等が使用できる。特に、メチロール基を有するアクリル樹脂又はその共重合体が好適に使用される。
Hereinafter, the example which uses the composition of this invention as a surface treating agent is demonstrated.
For use as a surface treatment agent, water and a binder resin are blended in addition to the above-described ammonium salt and urea. The binder resin is used, for example, in the form of a water emulsion.
As the binder resin, urethane resin, acrylic resin, or a copolymer thereof can be used. In particular, an acrylic resin having a methylol group or a copolymer thereof is preferably used.
表面処理剤において、各成分の配合は組成物全体を１００質量部としたときに、アンモニウム塩が１〜４３質量部、尿素が１〜３３質量部、バインダー樹脂が０〜１５質量部及び水４５〜９７が質量部であることが好ましい。
特に好ましくは、アンモニウム塩が３〜３０質量部、尿素が３〜２５質量部、バインダー樹脂が０〜１５質量部及び水が５５〜９２質量部である。
尚、バインダー樹脂が１質量部未満では、被塗布物への固着性が充分でないおそれがある。一方、バインダー樹脂が１５質量部より多いと、材料硬度が高くなったり、外観が低下するおそれがある。
In the surface treatment agent, each component is blended in an amount of 100 parts by mass of the entire composition, 1 to 43 parts by mass of ammonium salt, 1 to 33 parts by mass of urea, 0 to 15 parts by mass of binder resin and 45 water. It is preferable that -97 is a mass part.
Particularly preferably, the ammonium salt is 3 to 30 parts by mass, urea is 3 to 25 parts by mass, the binder resin is 0 to 15 parts by mass, and water is 55 to 92 parts by mass.
In addition, when the binder resin is less than 1 part by mass, there is a possibility that the adherence to an object to be coated is not sufficient. On the other hand, when the amount of the binder resin is more than 15 parts by mass, the material hardness may be increased or the appearance may be deteriorated.
表面処理剤は、被塗布物に各種コーティング法により塗布できる。コーティング方法は、ディッピング法、グラビアコーティング法、ナイフコーティング法、エアーフロスト法、スプレー加工等、公知の加工法が採用できる。
尚、要求される表面処理剤の粘度は加工法により異なるが、アクリル系又はセルロース系増粘剤を使用して適宜調整することが可能である。
表面処理剤を塗布後、乾燥させることにより、被塗布物の表面に本発明の組成物からなる消臭性膜（硬化物）を形成し、消臭性製品とすることができる。
The surface treatment agent can be applied to an object to be coated by various coating methods. As a coating method, a known processing method such as a dipping method, a gravure coating method, a knife coating method, an air frost method, or a spray processing can be adopted.
Although the required viscosity of the surface treatment agent varies depending on the processing method, it can be appropriately adjusted using an acrylic or cellulose thickener.
By applying the surface treatment agent and then drying, a deodorant film (cured product) made of the composition of the present invention can be formed on the surface of the object to be coated, thereby obtaining a deodorant product.
この表面処理剤の使用量は、被塗布物の要求特性にもよるが、好ましくは、被塗布物に対し乾燥質量で１〜２０ｇ／ｍ２、特に好ましくは、２〜１５ｇ／ｍ２とすることが望ましい。
表面処理剤（水エマルジョン）は、例えば、繊維、不織布、壁紙、接着剤、ウレタンフォーム、塗料製品、合板製品及びボード製品等の表面に塗布することにより、被塗布物にアルデヒドの消臭性を付与し消臭性製品とすることができる。これにより、外部環境の空気を消臭できる。特に、繊維、不織布、壁紙又はウレタンフォームの表面処理剤として好適に使用できる。
また、アルデヒドの発生源に本発明の組成物を塗布することでアルデヒドの発生量を低減できる。
The amount of the surface treatment agent varies depending on the required characteristics of the coating object, preferably, from 1 to 20 g / m 2 by dry weight relative to the coating object, particularly preferably, a 2 to 15 g / m 2 It is desirable.
The surface treatment agent (water emulsion) is applied to the surface of, for example, fibers, non-woven fabrics, wallpaper, adhesives, urethane foam, paint products, plywood products, board products, etc. It can be given a deodorant product. Thereby, the air of the external environment can be deodorized. In particular, it can be suitably used as a surface treatment agent for fibers, nonwoven fabrics, wallpaper or urethane foam.
Moreover, the generation amount of an aldehyde can be reduced by apply | coating the composition of this invention to the generation source of an aldehyde.
尚、本発明の組成物は、石膏ボード、壁紙、接着剤、ウレタンフォーム、又は塗料等を構成する材料に混合することにより、これらからのアルデヒドの発生を抑制すると共に消臭性を付与できる。即ち、消臭性製品を作製できる。この場合、各製品の乾燥質量１００質量部に対し、アンモニウム塩の配合量を。０．５〜２０質量部、尿素の配合量を０．５〜２０質量部とすることが好ましい。これらの配合量が０．５質量％未満では、消臭効果が充分でないおそれがあり、一方、２０質量％を越えると、基材としての物性が低下するおそれがある。
特に、硫酸アンモニウム及び尿素を含む組成物を配合した石膏ボードがホルムアルデヒド消臭性、硬化速度に優れ好ましい。
In addition, the composition of this invention can add deodorizing property while suppressing generation | occurrence | production of the aldehyde from these by mixing with the material which comprises a gypsum board, wallpaper, an adhesive agent, urethane foam, or a coating material. That is, a deodorant product can be produced. In this case, the compounding quantity of ammonium salt with respect to 100 mass parts of dry mass of each product. It is preferable that the blending amount of 0.5 to 20 parts by mass and urea is 0.5 to 20 parts by mass. If the blending amount is less than 0.5% by mass, the deodorizing effect may not be sufficient. On the other hand, if it exceeds 20% by mass, the physical properties as a substrate may be reduced.
In particular, a gypsum board containing a composition containing ammonium sulfate and urea is preferable because of its excellent formaldehyde deodorizing properties and curing speed.
また、本発明の消臭剤は、接着剤配合用ホルムアルデヒド消臭性組成物として特に有用である。例えば、パーティクルボード用の接着剤に使用できる。接着剤の具体例としては、メラミン系樹脂接着剤、尿素系樹脂接着剤等が挙げられる。 Moreover, the deodorizer of this invention is especially useful as a formaldehyde deodorant composition for adhesive compounding. For example, it can be used as an adhesive for particle boards. Specific examples of the adhesive include melamine resin adhesives and urea resin adhesives.
