Abstract
Description
本発明は塗料剥離剤に関する。更に詳しくは、Ｎ，Ｎ’−ジアルキル環状尿素化合物、アセチレングリコール類及び有機塩基を必須成分として含有することを特徴とする塗料剥離剤に関するものである。 The present invention relates to a paint remover. More specifically, the present invention relates to a paint remover comprising N, N'-dialkyl cyclic urea compound, acetylene glycols and an organic base as essential components.
自動車、オ−トバイ、家電製品、電子機器、スチ−ル製の家庭用品の製造において、腐食防止、美装の点から塗装が施されるが、その製造工程での塗装失敗品の回収、再塗装が行われる。これらの製品の塗装には、強力な皮膜が得られる、ポリエステル系樹脂、エポキシ樹脂、ポリエステル−エポキシ混合樹脂などの粉体塗料が使用されることが多く、これらの塗料を用いた塗膜は非常に強固で、これらの塗装皮膜の剥離には非常に困難がともなう。 In the manufacture of automobiles, motorcycles, home appliances, electronic equipment, and steel household products, painting is applied from the viewpoint of corrosion prevention and cosmetics. Painting is done. The coating of these products often uses powder coatings such as polyester resins, epoxy resins, and polyester-epoxy mixed resins that can provide strong coatings. It is difficult to remove these paint films.
現在、行われている剥離方法としては、ヤスリ、研磨砂などで物理的に削り落とす方法、プロパンバ−ナ−などの炎で焼却する方法などがあるが、これらの方法は作業性が悪く、多量の部品の回収作業には困難を伴う。 Currently, there are peeling methods such as a method of physically scraping with a file, sand, etc., and a method of incineration with a flame such as a propane burner. It is difficult to collect the parts.
化学的な方法として、塗料剥離剤で処理する方法がある。塗料剥離剤として、メチレンクロライドなどの塩素系溶剤（特許文献１）、Ｎ−メチルピロリドン（特許文献２）、エチレングリコールエーテル系溶剤、アセトン、またはアルコ−ル系溶媒などを使用する方法が開示されている。塩素系溶剤は低沸点の化合物が多く、揮発による空気中への拡散による環境汚染や労働安全衛生の観点から好ましいものではない。エチレングリコールエーテル系溶剤、ケトン類、Ｎ−メチルピロリドンを配合した塗料剥離剤は剥離能力が低く、塗料を剥離するために、高温で長時間処理する必要があるなど満足できるものではなかった。また、グリコールエーテル類、グリコール類、芳香族アルコール類、有機酸類から選ばれた２種類以上の化合物、及び蟻酸などの無機酸を含有する水溶液からなる塗料剥離剤組成物が開示されている（特許文献３）。この塗料剥離剤組成物では剥離力は比較的大きいものの、回収する塗装された基板そのものを腐食したり、剥離装置を腐食するなどの問題があった。
本発明は、ポリエステル系樹脂、エポキシ樹脂、ポリエステル−エポキシ混合樹脂などの粉体塗料により得られる強力な塗膜を、低温で容易に剥離できる塗料剥離剤を提供することを目的とするものである。 An object of the present invention is to provide a paint remover that can easily peel off a strong coating film obtained from a powder paint such as a polyester resin, an epoxy resin, and a polyester-epoxy mixed resin at a low temperature. .
上記課題は、金属表面と塗膜の間に溶剤が入り易くするように、浸透、湿潤剤としてアセチレングリコ−ル類を用い、さらに、樹脂を分解、可溶化する有機塩基、及び樹脂成分の溶解剤であるＮ，Ｎ’−ジアルキル環状尿素化合物類を併用することにより解決される。 The above problem is to use acetylene glycols as a penetrating and wetting agent so that the solvent can easily enter between the metal surface and the coating film, and further dissolve the organic base that decomposes and solubilizes the resin and the resin component. This can be solved by using N, N′-dialkyl cyclic urea compounds as agents together.
すなわち、本発明は、一般式（１） That is, the present invention relates to the general formula (1)
（式中、Ｒ１、Ｒ２は互いに同一もしくは相異なる炭素数１〜３のアルキル基を表し、ｎは１〜２の整数を表す。）で示されるＮ，Ｎ’−ジアルキル環状尿素化合物、一般式（２） (Wherein R 1 and R 2 represent the same or different alkyl groups having 1 to 3 carbon atoms, and n represents an integer of 1 to 2), N, N′-dialkyl cyclic urea compounds represented by: General formula (2)
（式中、ｍ、ｎは０〜５０の整数を表す。）で示されるアセチレングリコール類及び有機塩基を必須成分として含有することを特徴とする塗料剥離剤に関するものである。 (Wherein, m and n represent an integer of 0 to 50). The present invention relates to a paint remover characterized by containing acetylene glycols and an organic base as essential components.
本発明の塗料剥離剤は金属などの硬質表面の塗装を低温かつ短時間で除去できる。また、取り扱いが容易で、大気汚染の恐れがない塗料剥離剤である。 The paint remover of the present invention can remove a hard surface such as metal at a low temperature in a short time. In addition, it is a paint remover that is easy to handle and has no fear of air pollution.
本発明の塗料剥離剤に配合される前記一般式（１）で示されるＮ，Ｎ’−ジアルキル環状尿素化合物は、水によく溶解し、各種の樹脂、有機、無機化合物をよく溶解し、耐薬品性があり、安全性の高い非プロトン性極性溶媒である。具体的には、Ｎ，Ｎ’−ジメチルプロピレン尿素、Ｎ，Ｎ’−ジエチルエチレン尿素、１，３，４−トリメチルエチレン尿素、Ｎ，Ｎ’−ジメチルエチレン尿素、Ｎ，Ｎ’−ジプロピルエチレン尿素などが挙げられるが、入手が容易であることからＮ，Ｎ’−ジメチルエチレン尿素が好ましい。 The N, N′-dialkyl cyclic urea compound represented by the general formula (1) blended in the paint remover of the present invention dissolves well in water, dissolves various resins, organic and inorganic compounds well, It is an aprotic polar solvent with chemical properties and high safety. Specifically, N, N′-dimethylpropyleneurea, N, N′-diethylethyleneurea, 1,3,4-trimethylethyleneurea, N, N′-dimethylethyleneurea, N, N′-dipropylethylene Urea and the like can be mentioned, but N, N′-dimethylethyleneurea is preferable because it is easily available.
