【発明の名称】噴射による発泡ウレタンの迅速施工方法及びその装置
Document Type and Number:
Japanese Patent JP2696304
Kind Code:
B2
Abstract:
PURPOSE:To mix two liquids to form a foamed urethane layer having heat- insulation, heat retaining property, waterproof, chemicals-resistance, dew- prevention, sound-insulation and further, high adhesion, and high compression property by jet-spraying the mixed liquids not only on the inner wall faces of a building or a place where cracks have occurred but also on molded objects. CONSTITUTION:A-liquid and B-liquid are conducted into a jetting device body 2 from an A-liquid drum 3 holding A-liquid of crude MDI and a B-liquid drum 4 holding B-liquid or urethane resin and heated and pressurized appropriately and jetted at a specified mix ratio to an objective position through A-insulation hose 5 and B-insulation hose 6 connected to the jet device body 2 to form foaming urethane layer. A foaming urethane layer is quickly solidified. When the ambient temperature is high, the air in the drum is discharged to secure safety. Since A-liquid and B-liquid are jet-sprayed on a wall face, an irregular surface like a rock face arises on the foaming urethane surface and the external appearance and the quality are improved. Since the liquid mixture of A-liquid and B-liquid having a hydration action is used, the liquid penetrates in cracks and a perfect waterproofing effect can be obtained even from one side face.
