Description
【発明の詳細な説明】 産業上の利用分野 本発明は、均一な溶液としての防藻防黴製剤に関する。TECHNICAL FIELD OF THE INVENTION The present invention relates to antialgal and antifungal formulations as a homogeneous solution.
従来の技術 従来、製紙、化学、金属加工等における冷却水やプロセ
ス水等として多量の水が用いられているが、これら用水
系には微生物の増殖によるスライムが発生しやすく、例
えば、冷却水系では、熱交換器の伝熱効果の低下等の種
々の弊害の原因となつている。また、特に、工業用冷却
用水においては、藻類の発生も多い。このような藻類の
発生も、管を閉塞し、伝熱効率を低下させる。BACKGROUND ART Conventionally, a large amount of water has been used as cooling water or process water in papermaking, chemistry, metal processing, etc., but slimes due to the growth of microorganisms are easily generated in these water systems, and for example, in cooling water systems. This is a cause of various harmful effects such as a reduction in heat transfer effect of the heat exchanger. Further, especially in industrial cooling water, algae are often generated. The generation of such algae also clogs the tube and reduces the heat transfer efficiency.
更に、微生物や藻類は、水性塗料、溶剤型塗料、コーキ

樹脂成形品等の原材料や製品にも発生し、生産性を損な

It also occurs in raw materials and products such as resin molded products, impairing productivity and degrading product quality.

は、長時間静置したときに薬剤が沈降しやすい。Therefore, in the past, various algal and antifungal agents were used for water and raw materials,
In addition to the required objects such as products, anti-algal and anti-mildew is used. However, most of the antialgae and antifungal agents are water-insoluble or sparingly soluble powders or liquids, and thus are usually used as preparations such as emulsions, but their dispersibility, particularly,
Dispersibility in water systems such as water and emulsion is still
Is insufficient. Also, when the object is a solvent-based paint or resin, the solubility is generally small and the dispersibility is insufficient. Further, when a powdered drug is directly dispersed in a paint or the like, the drug tends to settle when left standing for a long time.

来、知られておらず、かかる製剤が強く要望されてい
る。Moreover, conventionally, in most cases, the antialgal agent and the antifungal agent have low compatibility with each other and no common solvent is found. Therefore, a formulation in a solution form containing both the antialgal agent and the antifungal agent. Has not hitherto been known, and there is a strong demand for such a formulation.

Since the preparation according to the present invention is an oily solution, it has excellent affinity for them and is very easy to disperse. Also,
A stable dispersion state is maintained for a long period of time. On the other hand,
When the application target is an emulsion type, the amount of the formulation is usually small, so that it is easily dispersed, and
Since the formulation itself remains insoluble or sparingly soluble in water, it has high water resistance, and for example, the algae-proofing and mildew-proofing effects are retained over a long period of time in a paint film or a resin molded product.
更に、本発明の製剤によれば、適用対象に防藻剤と防黴
剤とを一括して同時に配合することができる。Furthermore, according to the formulation of the present invention, the algae-proofing agent and the mildew-proofing agent can be simultaneously added to the application target at once.
