特許文献4は、ホルムアルデヒド等のVOCに対する分解性に優れている塗膜を形成することを可能とするために、水性合成樹脂エマルジョン及び光触媒活性を有する酸化チタンを含有し、水性エマルジョン塗料中での顔料のPWCが40〜95であることを特徴とするものである。
この発明は、従来の塗料よりもさらにホルムアルデヒド等の吸収・分解能力の高い塗料を提供することにある。 An object of the present invention is to provide a paint having higher absorption / decomposition capability such as formaldehyde than the conventional paint.
したがって、この発明に係る塗料は、少なくともエチレン尿素15〜30重量%、分散平衡剤2〜3重量%、第3類アミン類10〜16重量%及び金属塩類0.3〜0.8重量%含有する溶剤を、1〜4重量%含むことにある。 Therefore, the paint according to the present invention contains at least 15 to 30% by weight of ethylene urea, 2 to 3% by weight of a dispersion balancing agent, 10 to 16% by weight of tertiary amines, and 0.3 to 0.8% by weight of metal salts. 1 to 4% by weight of the solvent used.
また、前記金属塩類としては、硫酸マグネシウムであることが望ましいが、硫酸鉄等であっても良い。これによって、脱臭効果を得ることもできる。 The metal salt is preferably magnesium sulfate, but may be iron sulfate or the like. Thereby, a deodorizing effect can also be obtained.
また、前記分散平衡剤としては、エチレングリコール又はEDTAであることが望ましい。 The dispersion balancing agent is preferably ethylene glycol or EDTA.
さらに、前記第3類アミン類としては、トリエタノールアミンであることが望ましいが、ジエチルアミン等であっても良い。 Further, the tertiary amine is preferably triethanolamine, but may be diethylamine or the like.
さらにまた、前記溶剤は、アルコール類溶剤であることが望ましい。これによって油性塗料を形成できるものである。 Furthermore, the solvent is preferably an alcohol solvent. Thus, an oil-based paint can be formed.
また、前記溶剤は、水溶性溶剤であっても良い。これによって水性塗料を形成できるものである。 The solvent may be a water-soluble solvent. Thus, a water-based paint can be formed.
さらに、放出手段を具備する容器内に収容されることが望ましい。放出手段としてDME等の圧縮ガスを使用する容器内に収容されると、スプレー缶として壁等の塗布可能な塗料となる。さらに、コンプレッサ等による噴霧器の容器内に収納してスプレーすることも可能である。 Furthermore, it is desirable to be accommodated in a container having a discharge means. When accommodated in a container that uses compressed gas such as DME as the discharge means, it becomes a paint that can be applied to the wall or the like as a spray can. Furthermore, it is also possible to store and spray in a container of a sprayer such as a compressor.
また、本願発明は、ウレタン系油性クリア塗料を含むウレタン系塗料、アクリル系油性塗料、フッ素系塗料、サクビ系塗料等、メラニン系樹脂を除く全塗料に有効である。 Further, the present invention is effective for all paints excluding melanin resins, such as urethane paints including urethane oil-based clear paints, acrylic oil paints, fluorine paints, and rust paints.
この発明によれば、エチレン尿素、エチレングリコール等の分散平衡剤、及びトリエタノールアミン等の第3類アミン類によってホルムアルデヒドを効率良く吸収・分解することができるが、さらに金属塩類、特に硫酸マグネシウムを添加したことによって、ホルムアルデヒドの吸収・分解能力をさらに向上させることができる共に、脱臭効果も得ることができる。また、トリエタノールアミンは、金属の防蝕効果があるため、金属製建材等にも有効である。このように、本願発明の塗料は、広い範囲に適用できると共に、シックハウス症候群の原因を解消することができる。 According to the present invention, formaldehyde can be efficiently absorbed and decomposed by a dispersion balancing agent such as ethylene urea and ethylene glycol and a tertiary amine such as triethanolamine. By adding, the ability to absorb and decompose formaldehyde can be further improved, and a deodorizing effect can also be obtained. Triethanolamine is also effective for metal building materials and the like because it has a metal anticorrosive effect. Thus, the paint of the present invention can be applied to a wide range and can eliminate the cause of sick house syndrome.
本願発明に係る塗料は、エチレン尿素15〜30重量%、エチレングリコール(分散平衡剤)2〜3重量%、トリエタノールアミン(第3類アミン類)10〜16重量%及び硫酸マグネシウム(金属塩類)0.3〜0.8重量%含有させた水溶性溶剤又はアルコール系溶剤を、ウレタン系油性クリア塗料を含むウレタン系塗料、アクリル系油性塗料、フッ素系塗料、サクビ系塗料等、メラニン系樹脂を除く全塗料のいずれか一つに、1〜4重量%含ませたものである。 The paint according to the present invention is made of 15 to 30% by weight of ethylene urea, 2 to 3% by weight of ethylene glycol (dispersion balancing agent), 10 to 16% by weight of triethanolamine (class III amines), and magnesium sulfate (metal salts). A water-soluble solvent or alcohol solvent containing 0.3 to 0.8% by weight of a melanin resin such as a urethane paint, an acrylic oil paint, a fluorine paint, a sugar paint, etc., including a urethane oil-based clear paint. Any one of all paints except 1 to 4% by weight is included.
また、前記トリエタノールアミンに代えてジニチルアミン等その他のアミン類を用いても同様の効果が得られる。このトリエタノールアミンは、金属の防蝕効果があるため、金属製建材に用いた場合には、その表面を保護する効果が得られる。 The same effect can be obtained by using other amines such as dinitylamine instead of the triethanolamine. Since this triethanolamine has a metal anticorrosive effect, when used for a metal building material, the effect of protecting the surface is obtained.
さらに前記硫酸マグネシウムに代えて硫酸鉄等の他の金属塩類を用いることもできる。しかしながら、現在の実験結果では、硫酸マグネシウムを用いた場合が最もホルムアルデヒドの吸収・分解が顕著であり、且つ他の悪臭成分に対する脱臭効果も確認できた。 Further, other metal salts such as iron sulfate can be used in place of the magnesium sulfate. However, in the present experimental results, the absorption and decomposition of formaldehyde was most remarkable when magnesium sulfate was used, and the deodorizing effect against other malodorous components could be confirmed.
エチレン尿素27.5重量%、エチレングリコール(分散平衡剤)2.5重量%、トリエタノールアミン(第3類アミン類)13重量%及び硫酸マグネシウム(金属塩類)0.6重量%含有させた水溶性溶剤又はアルコール系溶剤を、ウレタン系塗料に1.5重量%含ませ、実験用塗料を作成した。 Water solution containing 27.5% by weight of ethylene urea, 2.5% by weight of ethylene glycol (dispersion balancing agent), 13% by weight of triethanolamine (class III amines) and 0.6% by weight of magnesium sulfate (metal salts) An experimental solvent was prepared by adding 1.5% by weight of an organic solvent or an alcohol solvent to the urethane paint.
ガラス容器(真空デシケータ、容積約21L)を用い、容器内のほぼ中央に試料(ガラス板上に上記塗料を塗布、風乾放置、面積100cm2)をセットし、容器内を減圧後、これにホルムアルデヒドを含む調整空気を封入する。静置して一定時間後に容器内の空気を速やかに採取し、その気中濃度を測定する。ホルムアルデヒドの暴露条件は、初期設定濃度8.91PPMとし、温度20℃、湿度50%で行った。この一過暴露減衰法による試験結果を下記に示す。 Using a glass container (vacuum desiccator, volume of about 21 L), set the sample (applying the above-mentioned paint on a glass plate, air-drying, area 100 cm 2 ) in the middle of the container, depressurize the container, and formaldehyde Enclose the adjusted air containing. After standing for a certain period of time, the air in the container is quickly collected and the concentration in the air is measured. The exposure conditions for formaldehyde were an initial concentration of 8.91 PPM, a temperature of 20 ° C., and a humidity of 50%. The test results by this transient exposure decay method are shown below.
以上の結果が示すように、ガラス容器内のホルムアルデヒドは、約50時間経過後にはほとんど検出されなかった。これによって、平成15年7月1日から施行された建築基準法の改正に基づくシックハウス症候群の主要因であるホルムアルデヒドの改正基準値0.08PPM以下をクリアすることができるものである。 As the above results show, almost no formaldehyde in the glass container was detected after about 50 hours. As a result, the revision standard value of 0.08 PPM or less of formaldehyde, which is the main factor of sick house syndrome based on the revision of the Building Standard Law, which came into effect on July 1, 2003, can be cleared.
