【発明の属する技術分野】
本発明は、次亜塩素酸カルシウムを主成分とする晒粉組成物に関するものであり、晒粉は浄化槽、プールの消毒、殺菌などに利用されている有用な化合物である。
【０００２】
【従来の技術】
従来、晒粉組成物としては、次亜塩素酸カルシウムに水酸化カルシウム（消石灰）を配合することにより、安定な次亜塩素酸カルシウム組成物が得られることが知られている（特開昭５６−１４４０２号参照）。
【０００３】
しかしながら、この次亜塩素酸カルシウム組成物では溶解速度を調整する機能があるがその溶解速度調整機能は十分ではないため、溶解速度のさらに遅い晒粉組成物が求められている。
【０００４】
一方、晒粉は浄化槽、プールの消毒、殺菌などに利用されている有用な化合物であるが、強力な酸化剤でもあるため、塩素化イソシアヌル酸（有機系晒粉）、油、油脂、グリースなどの有機化合物、還元剤、アミン類などと混合すると発熱、発火、爆発の危険がある。そのため、晒粉に有機物を配合した例はない。次亜塩素酸ナトリウムの希薄水溶液に有機高分子界面活性剤を粘度調整剤として配合した例が知られているのみである。
【０００５】
【発明が解決しようとする課題】
本願発明の目的は、浄化槽又は排水処理等に使用される場合、溶解速度が遅く効力が長時間持続する新規な晒粉組成物を提供することにある。
【０００６】
【課題を解決するための手段】
本発明者らは、上記の課題の解決のため鋭意検討を行った結果、無機系晒粉に界面活性機能を有する化合物の少なくとも１種を配合することにより、安全性、安定性を損なうことなく溶解速度を調整することができることを見出し、本発明を完成するに至ったものである。すなわち、本願発明は、次亜塩素酸カルシウムを主成分とする無機系晒粉に、界面活性機能を有する化合物の少なくとも１種を配合してなることを特徴とする晒粉組成物である。
【０００７】
以下、本願発明についてさらに詳細に説明する。
【０００８】
本願発明における無機系晒粉とは、次亜塩素酸カルシウムを主成分とするものであれば特に限定されるものでなく、例えば、高度晒粉（次亜塩素酸カルシウム無水塩、次亜塩素酸カルシウム・２水塩）や６０％高度晒粉（次亜塩素酸カルシウム・１／２塩基性塩）及びこれらの混合物があげられる。
【０００９】
本願発明の晒粉組成物は、次亜塩素酸カルシウムを主成分とする無機系晒粉に、界面活性機能を有する化合物の少なくとも１種を配合してなるものである。ここに、界面活性機能を有する化合物とは、界面活性機能を有する化合物であれば特に限定するものでなく、例えば、アニオン系界面活性剤であるポリオキシエチレンアルキル硫酸塩、ノニオン系界面活性剤であるポリオキシエチレン−ポリオキシプロピレン共重合体、ソルビタン脂肪酸エステル、グリセリン脂肪酸エステル、セルロース誘導体、ポリビニルアルコール誘導体があげられる。なお、これらの界面活性機能を有する化合物を２種以上配合してなる場合の混合割合は特に限定するものでない。
【００１０】
界面活性機能を有する化合物の少なくとも１種の配合量は、溶解速度をより遅く調整するため、次亜塩素カルシウムを主成分とする無機系晒粉に対し、０．１〜２０重量％が好ましく、さらに有効成分濃度を維持するため、０．３〜１０重量％がさらに好ましい。なお、本願発明の晒粉組成物の形態は粉末状、顆粒状、錠剤状等、いずれの形態でもよい。
【００１１】
本願発明の晒粉組成物には、その特性を損なわなければ、界面活性機能を有する化合物の他に、水酸化カルシウム、合成ゼオライト、珪酸ゲル等を配合してもよい。
【００１２】
本願発明における晒粉組成物の製造方法は、特に限定するものでなく、例えば、無機系晒粉製造工程中の乾燥工程の前工程で、界面活性機能を有する化合物の少なくとも１種を添加することにより製造できる。また、形態が粉末状である無機系晒粉の場合は、無機系晒粉と界面活性機能を有する化合物の少なくとも１種を簡単な混合機（例えば、リボンミキサー等）で混合することにより製造ができる。 形態が顆粒状である無機系晒粉の場合は、前記製造工程で界面活性機能を有する化合物の少なくとも１種を配合するほか、顆粒に成形する前工程で、界面活性機能を有する化合物の少なくとも１種を混合し顆粒に成形するか、顆粒化工程後に混合する方法等で製造できる。形態が錠剤の無機系晒粉の場合は、打錠原料が粉末状のものにあっては、前記粉末状晒粉組成物の製造方法で製造したものを打錠することにより、また、顆粒状の原料を使用するときは、前記顆粒状晒粉組成物の製造方法で製造したものを打錠することにより製造できる。この製造の際に、スケール防止剤としての合成ゼオライトなどの他の添加物を同時に配合することは何等差し支えない。

BACKGROUND OF THE INVENTION
The present invention relates to a bleaching powder composition containing calcium hypochlorite as a main component, and bleaching powder is a useful compound that is used for disinfection and sterilization of septic tanks and pools.
[0002]
[Prior art]
Conventionally, as a bleached powder composition, it is known that a stable calcium hypochlorite composition can be obtained by adding calcium hydroxide (slaked lime) to calcium hypochlorite (Japanese Patent Laid-Open No. 56). -14402).
[0003]
However, this calcium hypochlorite composition has a function of adjusting the dissolution rate, but the function of adjusting the dissolution rate is not sufficient. Therefore, a bleaching powder composition having a slower dissolution rate is required.
[0004]
On the other hand, bleaching powder is a useful compound used for sterilization and sterilization of septic tanks, pools, etc., but it is also a powerful oxidizing agent, so chlorinated isocyanuric acid (organic bleaching powder), oil, fats and greases If mixed with organic compounds, reducing agents, amines, etc., there is a risk of heat generation, fire, and explosion. Therefore, there is no example which mix | blended organic substance with bleaching powder. There are only known examples in which a dilute aqueous solution of sodium hypochlorite is blended with an organic polymer surfactant as a viscosity modifier.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a novel bleached powder composition having a slow dissolution rate and a long-lasting effect when used in a septic tank or wastewater treatment.
[0006]
[Means for Solving the Problems]
As a result of intensive studies for solving the above-mentioned problems, the present inventors have blended at least one compound having a surface active function into an inorganic bleached powder without impairing safety and stability. It has been found that the dissolution rate can be adjusted, and the present invention has been completed. That is, the present invention is a bleached powder composition comprising an inorganic bleached powder mainly composed of calcium hypochlorite and at least one compound having a surface active function.

[0009]
The bleached powder composition of the present invention is obtained by blending at least one compound having a surface active function with an inorganic bleached powder containing calcium hypochlorite as a main component. Here, the compound having a surface active function is not particularly limited as long as it is a compound having a surface active function, and examples thereof include polyoxyethylene alkyl sulfates and nonionic surfactants which are anionic surfactants. Specific polyoxyethylene-polyoxypropylene copolymers, sorbitan fatty acid esters, glycerin fatty acid esters, cellulose derivatives, and polyvinyl alcohol derivatives. In addition, the mixing ratio in the case of blending two or more compounds having these surface active functions is not particularly limited.
[0010]
The blending amount of at least one compound having a surface active function is preferably 0.1 to 20% by weight with respect to the inorganic bleaching powder containing calcium hypochlorite as a main component in order to adjust the dissolution rate slower. Furthermore, in order to maintain an active ingredient density | concentration, 0.3 to 10 weight% is further more preferable. The form of the bleached powder composition of the present invention may be any form such as powder, granule, tablet and the like.
[0011]
The bleaching powder composition of the present invention may contain calcium hydroxide, synthetic zeolite, silicic acid gel, etc. in addition to the compound having a surface active function, as long as the characteristics are not impaired.
[0012]
The manufacturing method of the bleaching powder composition in this invention is not specifically limited, For example, adding at least 1 sort (s) of the compound which has a surface active function in the pre-process of the drying process in an inorganic type bleaching powder manufacturing process. Can be manufactured. In the case of an inorganic bleaching powder in the form of powder, the inorganic bleaching powder and at least one compound having a surface active function can be mixed by a simple mixer (for example, a ribbon mixer). it can. In the case of an inorganic bleaching powder in the form of granules, at least one compound having a surface active function is added in the previous step of forming into granules, in addition to blending at least one compound having a surface active function in the production process. It can be produced by mixing seeds into granules and mixing them after the granulation step. When the form is a tablet inorganic bleaching powder, if the tableting raw material is in powder form, by tableting the one produced by the method for producing the powdered bleaching composition, When using these raw materials, it can be produced by tableting the one produced by the method for producing the granular bleached powder composition. During this production, it is possible to mix other additives such as synthetic zeolite as a scale inhibitor at the same time.
