販されている、仮囲鋼板類の塗膜を剥離するための組成
液および剥離装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a composition liquid and a stripping device for stripping the paint film of temporary enclosure steel plates, which are called safety steel plates or guard steel plates and are commercially available. .
仮囲鋼板類は建築現場をその周囲から隔離し、その現場
内部で発生する可能性がある危険が外部に波及すること
を防止するため設置される。Temporary enclosure steel plates are installed to isolate a construction site from its surroundings and to prevent dangers that may occur inside the site from spreading outside.
これら鋼板類は一般にセルロース系あるいはアルキド樹

ため鋼板類を繰返し使用するには、一定期間をおいて塗
替えを行う必要があった。These steel sheets are generally coated with cellulose-based or alkyd resin-based lacquer, but over time, the coating film swells, peels, cracks, etc., damaging the base of the copper sheets, and at the same time causing discoloration. Appearance deteriorates. For this reason, in order to use steel plates repeatedly, it was necessary to repaint them after a certain period of time.

する点が少なくなかった。In order to repaint, the old paint must be completely peeled off, but in the past, a strong alkaline remover was generally applied, peeled off using a leather plow, etc., and the finish was then thoroughly washed with water. However, this method requires a lot of effort to remove, and there are many problems that require improvement, such as rust formation due to washing with water, drainage treatment, and irritation to the skin.
この発明は上記問題点に着目しなされたものである。そ

仮囲鋼板類塗膜剥離用の組成液および剥離装置を提案す
るにある。This invention has been made in view of the above-mentioned problems. The purpose is to propose a composition liquid and a stripping device for stripping coatings on temporary steel plates that have good work efficiency and can improve the above-mentioned problems.

It is a device for peeling off the coating film, and includes a dipping tank, a hanging frame loaded with multiple steel plates and suspended from the dipping tank, and capable of being lifted.
And, it is characterized by having a net frame having a net surface covering the bottom surface of the dipping tank and collecting the peeling coating film.
この剥離用組成液として好適な組成の一例は下表の通り
である。An example of a suitable composition for this stripping composition is shown in the table below.
塩化メチレン（ＣＨ□ｃ ｅ ｚ） ７９重

10” Dimethyl sulfoxide 0.1 Triethanolamine 0.005 Methanol 5 Dimethylformamide 1 Water
5 - The above-mentioned composition liquid 1 is placed in the rectangular parallelepiped-shaped dipping tank 2 shown in FIG. The steel plates 6 were stacked one on top of the other, lifted by a forklift or the like, suspended together with the hanging frame 5 in a dipping tank, and immersed in the stripping composition liquid 1.

塗膜は網枠４の網目３で捕集して除去し、繰返し板間鋼
板類を浸漬して塗膜の剥離を行なうことができた。Most of the coatings on steel plates were peeled off and removed by immersion for 5 to 40 minutes. When the hanging frame was lifted, some of the paint film that remained on the surface of the steel plates dried within a few minutes after being lifted, but it could be easily removed by lightly brushing it off with a brush or the like. The coating film peeled off in the tank was collected and removed by the mesh 3 of the mesh frame 4, and the interplate steel plates were repeatedly immersed to remove the coating film.
なお、吊枠５に重ねて載置する鋼板類６相互間には組成
液が流れる間隙が必要であり、相互間にスペーサー等を
介挿する場合もある。Note that a gap is required between the steel plates 6 stacked on the hanging frame 5 for the composition liquid to flow therebetween, and a spacer or the like may be inserted between the steel plates 6 in some cases.

ならない。The above composition beam is mainly composed of two chlorinated solvents, methylene dichloride and propylene dichloride, and the ratio is (70~
90): The range of (30 to 10) is suitable. Dimethyl sulfoxide, methanol, dimethylformamide, etc. do not necessarily need to be added, but they are effective in promoting penetration of the chlorinated solvent into the coating film, and are added as appropriate depending on the composition of the coating film. Triethanolamine is effective as a stabilizer for chlorinated solvents, and other stabilizers can also be used. Water floats on the surface of the composition liquid and is effective in suppressing evaporation of the composition liquid. This composition liquid can be used repeatedly by collecting and removing the peeled coating film with a mesh frame, but the solvents absorbed by the coating film must be replenished from time to time to maintain the desired composition.
また、組成液中には塗膜成分の一部が溶出し徐々に蓄積
されるので、長期的にはこれら成分を蒸留等により除去
をする必要がある。Further, since some of the coating film components are eluted and gradually accumulated in the composition solution, it is necessary to remove these components by distillation or the like in the long term.

あり、有害廃液の排出もない。This invention consists of the above configuration. With this composition solution for stripping the temporary steel plate coating, most of the coating can be peeled off by simply immersing the steel plate for a short time, and the entire coating can be easily removed. Compared to the conventional method of applying a stripping agent and stripping the skin with a plow or the like, it has higher work efficiency, can process a large amount at a time, and does not discharge harmful waste fluids.

しく向上せしめることができる。This stripping device has a hanging frame that can load and suspend multiple steel plates in a dipping tank, making it efficient to immerse a large amount of steel plates in a tank in a short period of time. Good. When using the stripping composition according to the present invention, most of the coating film will peel off inside the tank, but the peeled coating film can be collected by a mesh frame and discharged outside the tank, so steel plates can be continuously immersed. This makes it possible to repeatedly remove the coating film. Therefore, in combination with this stripping composition, this stripping device can significantly improve the efficiency of coating stripping.
