Abstract
Description
本発明は、湿式塗装ブースにおいて、微生物の繁殖の抑制と共に悪臭の発生を防止する塗装ブース循環水用添加剤及びその使用方法に関する。 The present invention relates to a coating booth circulating water additive and a method of using the same for suppressing the growth of microorganisms and preventing the generation of malodor in a wet coating booth.
自動車車体等の複雑な形状の物体の塗装には、スプレーガンを用いて塗料をミスト化して吹付ける吹付け塗装法が用いられる。吹付け塗装では、被塗物に付着するのは平均して塗料の３０％程度である。そのため、吹付け塗装を行う際、被塗物に付着しなかった塗料を湿式塗装ブースのウォーターカーテンにより捕捉して、未塗着の塗料ミストを水中に捕集するのが一般的である。水中に捕集された塗料ミストは凝集するので、遠心分離等の適当な固液分離法によりスラッジ状に凝集した塗料ミストを塗料粕として水から分離する。塗料粕が除去された水は、通常は塗装ブースに戻されて循環利用される。 For painting an object having a complicated shape such as an automobile body, a spray painting method is used in which a paint gun is misted and sprayed. In spray painting, on average, about 30% of the paint adheres to the object. For this reason, when spray coating is performed, it is common to capture the paint that has not adhered to the object to be coated with a water curtain in a wet painting booth and collect uncoated paint mist in water. Since the paint mist collected in water agglomerates, the paint mist aggregated in a sludge form is separated from water as a paint soot by an appropriate solid-liquid separation method such as centrifugation. The water from which the paint soot has been removed is usually returned to the painting booth and recycled.
自動車車体等に使用される吹付け塗料は、通常はアクリル系又はウレタン系の焼付け型塗料である。塗料ブース水中に含まれる塗料ミストは、焼付けを受けておらず、未硬化であることから、粘着性が高く塗料ミストの凝集物が固液分離装置、循環ポンプ、配管などに付着する。この塗料ミストを回収しないと循環水としての再利用が困難になる。また、一度付着した塗料を除去するのに多大な労力を必要とする。この対策として、各種のカチオン性凝集剤や不粘着化剤が提案されている。例えば、ジメチルアミン・エピクロルヒドリン縮合物等のカチオン性有機高分子凝集剤とノニオン性有機高分子凝集剤を使用する方法（特許文献１）やカチオン性有機高分子凝集剤とカチオン化セルロースを使用する方法（特許文献２）が知られている。 Spray paints used for automobile bodies and the like are usually acrylic or urethane baked paints. The paint mist contained in the paint booth water has not been baked and is uncured, and therefore has high adhesiveness and agglomerates of the paint mist adhere to solid-liquid separators, circulation pumps, piping, and the like. If this paint mist is not recovered, it is difficult to reuse it as circulating water. Moreover, a great amount of labor is required to remove the paint once adhered. As a countermeasure against this, various cationic flocculants and non-tackifying agents have been proposed. For example, a method using a cationic organic polymer flocculant such as dimethylamine / epichlorohydrin condensate and a nonionic organic polymer flocculant (Patent Document 1) or a method using a cationic organic polymer flocculant and cationized cellulose (Patent Document 2) is known.
また、一般的な塗料成分中に含まれる有機溶剤としてトルエン、キシレン、酢酸エチルの他にメチルイソブチルケトンに代表されるようなケトン類が多量に使用されている。湿式塗装ブース循環水は、余剰塗料や溶剤を多量に含み富栄養的であり、更に循環水が長期間循環使用されるため、循環水は、腐敗しやすく、腐敗臭（アルデヒド、カルボン酸類、硫黄化合物、窒素化合物）を発生する。塗装工場での作業現場では、臭気による作業環境の悪化及びその周辺地域では、住民からの苦情の原因となる。この微生物の繁殖の抑止、悪臭の発生防止に殺菌剤の使用（特許文献３）やオゾン使用（特許文献４）が提案されている。 In addition to toluene, xylene, and ethyl acetate, ketones represented by methyl isobutyl ketone are used in large quantities as organic solvents contained in general paint components. Wet paint booth circulating water is rich in excess paint and solvent and is eutrophic, and since circulating water is circulated and used for a long period of time, the circulating water is prone to spoilage and rot odor (aldehyde, carboxylic acids, sulfur Compound, nitrogen compound). At the work site in a paint factory, the working environment deteriorates due to odors, and in the surrounding area, it causes complaints from residents. The use of a bactericide (Patent Document 3) and the use of ozone (Patent Document 4) have been proposed to suppress the growth of microorganisms and prevent the generation of malodors.
塗装ブースに係わる悪臭の防止には各種の方法が提案されているが、オゾンを使用する方法では別個の装置を必要とする。また殺菌剤を使用する方法でも、これまで提案されている薬剤は、塗装ブース循環水のように有機物を多量に含む水に対しては殺菌効力が失活するため、充分な防臭が出来ない状況である。本発明は、塗装ブース循環水中の腐敗菌を効率良く抑制し、ブース中の悪臭を防止するカチオン性添加剤及びその使用方法を提供することを目的とする。 Various methods have been proposed to prevent bad odors related to the painting booth, but a method using ozone requires a separate device. In addition, even in the method using a disinfectant, the agents proposed so far are incapable of sufficient deodorization because the disinfecting effect is deactivated for water containing a large amount of organic substances such as paint booth circulating water. It is. It is an object of the present invention to provide a cationic additive that efficiently suppresses spoilage bacteria in the circulating water in a painting booth and prevents malodor in the booth and a method for using the same.
