収剤に関する。More specifically, it is manufactured using formalin-based resin. This product relates to an absorbent for small amounts of formaldehyde generated from various wood products.
（従来の技術及びその問題点） ホルマリン系樹脂には尿素−ホルマリン樹脂。(Conventional technology and its problems) Formalin-based resin is urea-formalin resin.
メラミン−ホルマリン樹脂、フェノール−ホルマリン樹
脂、あるいはこれらの共縮合樹脂などがあり、これらは
広く生産され１合板、化粧板、パーチクルボードなどの
木質用接着剤として多量に使用されている。There are melamine-formalin resins, phenol-formalin resins, and co-condensed resins thereof, which are widely produced and used in large quantities as adhesives for wood materials such as plywood, decorative boards, and particle boards.
しかしながら、この様な木工製品（以下、単に木工製品

要望されている。However, due to the formalin resin used in such wood products (hereinafter simply referred to as wood products), free formaldehyde is released into the atmosphere even though it receives electricity, which can irritate the mucous membranes of the eyes. Since it can cause health problems such as film damage, headaches, etc., there is a need for preventive measures.
どの問題を解決する方法として、従来よりホルムアルデ

酸塩付加物からなる混合物を使用する方法などがある。For example, there is a method of applying an organic amine compound to the woodwork product, a method of applying an acrylic acid hydrazide polymer compound, or a method of using a mixture of an amino compound and an acidic sulfite adduct of glyoxal. .

硫酸塩付加物からなる混合物を使用する方法も、ホルム
アルデヒドの吸収速度が必らずしも充分であるとは言え
ず、加えて高価でもあり実用上普及していない。However, among these methods, the method using organic amino acids/compounds has insufficient formaldehyde adsorption ability, and the method using acrylic acid hydrazide-based polymer compounds is difficult to use when using wood materials such as plywood. The major drawback is that it causes discoloration. The method of using a mixture of an amine compound and an acidic sulfite adduct of glyoxal also does not necessarily provide a sufficient rate of formaldehyde absorption, and is also expensive, so it is not widely used in practice.

願した。In view of the above circumstances, the inventors of the present invention have conducted extensive studies in order to obtain an inexpensive formaldehyde absorbent that has strong formaldehyde adsorption ability, does not adversely affect the human body or wood products after use, and is also inexpensive. As a result, it was discovered that if an aqueous solution containing sodium sulfite and ammonium salt is used, this aqueous solution reacts extremely quickly with formaldehyde emitted from wood products, making formaldehyde harmless. I applied.

。Since the permeability into the interior of the woodwork product is insufficient, even if this aqueous solution is applied to the woodwork product, free formaldehyde generated from inside the wood that makes up the woodwork product may be released into the atmosphere after a long period of time. It turns out that there are some drawbacks.

In particular, the ammonium salt is an ammonium salt of a strong acid, and sodium sulfite and ammonium It is preferable that the ratio of the salt is equivalent to 2:0.98 to 1.02, and the active surfactant is H, L, B, or 10 to 140 nonionic surfactants.
本発明を更に詳細に説明する。The present invention will be explained in more detail.
本発明で使用する亜硫酸ソーダ及びアンモニウム塩は、
何れもホルムアルデヒドの吸収剤として有効であること

It is known that all of these are effective as formaldehyde absorbents.
即ち、亜硫酸ソーダは（１）式に示す如くホルムアルデ

(2) If sodium sulfite or ammonium salt is used alone as a formaldehyde absorbent, caustic soda or acid will be produced.
この生成した苛性ソーダや酸が人体や木工製品に悪影響
を及ぼすと云う問題が発生する。A problem arises in that the generated caustic soda and acid have an adverse effect on the human body and wood products.
ところが１本発明のホルムアルデヒド吸収剤水溶液は、
その成分として亜硫酸ソーダとアンモニウム塩を含有し
ている。従ってホルムアルデヒドを吸収した後、生成す

塩の割合が、当量比で２：０．９８〜１．０２の割合で
あれば、生成した苛性ソーダと強酸が過不足なく反応す
るので特に好ましい。However, the formaldehyde absorbent aqueous solution of the present invention is
Its ingredients include sodium sulfite and ammonium salts. Therefore, after absorbing formaldehyde, the generated caustic soda and acid are neutralized to produce soda salt.
The above problem can be solved. In particular, when the ammonium salt is a strong acid ammonium salt, it is convenient because the generated soda salt is a neutral salt, and furthermore, the ratio of sodium sulfite and strong acid ammonium salt in the formaldehyde absorbent aqueous solution is 2 in equivalent ratio. : A ratio of 0.98 to 1.02 is particularly preferable because the generated caustic soda and strong acid react in just the right amount.
強酸のアンモニウム塩は塩化アンモニウム、硫酸アンモ
ニウム、燐酸アンモニウム、硝酸アンモニウムのいずれ
かであれば、これらは入手しやすくかつ廉価であるばか

ニウム塩から発生する酸は、何れも苛性ソーダと速やか
に反応し中性塩を生成するので好都合である。Ammonium salts of strong acids include ammonium chloride, ammonium sulfate, ammonium phosphate, and ammonium nitrate. Not only are these easy to obtain and inexpensive, but the acids generated from the ammonium salts in the process of formalde absorption are Both are advantageous because they quickly react with caustic soda to produce neutral salts.
本発明で更に重要なことは、実施例及び比較例から明ら

ム塩を単独に使用するよりも１本発明の如（両者を併用
する方が、その理由は不明なるもホルムアルデヒドの吸
収能力が増加すると云うことである。What is more important in the present invention is that, as is clear from the Examples and Comparative Examples, it is better to use sodium sulfite or ammonium salt as an absorbent alone (as in the present invention) than to use both sodium sulfite or ammonium salt alone. Although it is unclear, the ability to absorb formaldehyde increases.
