Abstract
Description
本発明は、光触媒を用いたスプレー式の除菌及び分解剤に関する。 The present invention relates to a spray-type disinfecting and decomposing agent using a photocatalyst.
ある種の酸化チタンには光が照射されることにより酸化分解能が出現し、細菌の除菌、殺菌作用や有機物の分解作用があることは公知である。
また、酸化チタンの結晶形によっても出現する光触媒作用に大きな相違が認められることも知られていて、例えば特許文献１，２には、鑓型形状の酸化チタン結晶粒子と球型形状の酸化チタン結晶粒子とを組み合せたウィルス力価低下含有体を開示する。
しかし、これら従来の光触媒は建築物内装材、家電機器等にコーティング使用されているものの、高いコーティング技術と専用設備が必要であり、一般家庭には普及されていないのが現状であった。
It is well known that certain types of titanium oxide exhibit oxidative degradability when irradiated with light, and have bacteria sterilization, bactericidal action and organic substance decomposition action.
In addition, it is also known that a large difference is observed in the photocatalytic action that appears depending on the crystal form of titanium oxide. For example, Patent Documents 1 and 2 disclose a bowl-shaped titanium oxide crystal particle and a spherical titanium oxide. Disclosed is a virus titer-reducing body in combination with crystal particles.
However, although these conventional photocatalysts are used as coating materials for building interior materials, home appliances, etc., they require high coating technology and dedicated equipment, and are not widely used in ordinary homes.
本発明は、一般の人が手軽に使用できるスプレー式の光触媒からなる除菌分解剤の提供を目的とする。 An object of the present invention is to provide a disinfecting / decomposing agent comprising a spray-type photocatalyst that can be easily used by ordinary people.
本発明に係る除菌分解剤は、水系で製造された光触媒とジメチルエーテル（ＤＭＥ）を充填したスプレー缶にしたことを特徴とする。
ここで水系で製造された光触媒とは光触媒の製造に用いる分散液、溶解液、沈殿物生成液等に水溶液を用いたことを意味する。
このように水系で製造された光触媒は親水性が高く、ジメチルエーテルとの親和性が高いので、このジメチルエーテルを噴射剤に用いたスプレー缶にすることが可能になったものである。
本発明にて除菌分解剤は、除菌、殺菌作用及び有機物の分解作用を有するものをいう。
The disinfecting and decomposing agent according to the present invention is characterized in that it is a spray can filled with an aqueous photocatalyst and dimethyl ether (DME).
Here, the photocatalyst produced in an aqueous system means that an aqueous solution is used for a dispersion, a solution, a precipitate production liquid and the like used in the production of the photocatalyst.
Thus, since the photocatalyst manufactured by the aqueous system has high hydrophilicity and high affinity with dimethyl ether, it becomes possible to make a spray can using this dimethyl ether as a propellant.
In the present invention, the disinfecting / decomposing agent means one having disinfecting, bactericidal action and organic substance decomposing action.
また、本発明において、水系で製造された光触媒はＯＨ基を有する酸化チタンであってよく、このような酸化チタンの例としてはペルオキソ基で修飾された酸化チタン分散水溶液にＯＨ基を有する球型酸化チタンを混合したものが挙げられる。 In the present invention, the photocatalyst produced in an aqueous system may be titanium oxide having an OH group. Examples of such titanium oxide include a spherical type having an OH group in a titanium oxide dispersed aqueous solution modified with a peroxo group. What mixed the titanium oxide is mentioned.
本発明は、水系で製造された光触媒を用いたことにより、ジメチルエーテルとの混合が可能になり、スプレー缶に充填することができる。
これにより、一般の人が家庭や職場等にて手軽に使用することが可能になる。
また、使用方法も広がり、例えば家庭では、玄関、下駄箱、客間、リビング、キッチン、寝室、子供室等において、手軽に壁、天井、照明器具、カーテン、ブラインド、家具等のあらゆる所にスプレーすることで除菌、抗菌、及び脱臭が可能となる。
また、車両のシートや車内にスプレーすることで車内の除菌や脱臭ができる。
さらには、病院の待合室、病室又は学校、保育園、交通機関内等においてもスプレーすることでウィルス等の感染予防に寄与することができる。
In the present invention, by using a photocatalyst produced in an aqueous system, mixing with dimethyl ether becomes possible, and it can be filled in a spray can.
This makes it possible for ordinary people to use it easily at home or at work.
In addition, the usage is widespread, for example, at home, in the entrance, clog box, guest room, living room, kitchen, bedroom, children's room, etc., easily spray everywhere on the wall, ceiling, lighting equipment, curtains, blinds, furniture, etc. This makes it possible to disinfect, antibacterial, and deodorize.
Moreover, disinfecting and deodorizing the inside of a vehicle can be performed by spraying on the vehicle seat or the inside of the vehicle.
Furthermore, spraying in hospital waiting rooms, hospital rooms or schools, nurseries, transportation facilities, etc. can contribute to the prevention of infections such as viruses.
図１に本発明に係るスプレー缶式除菌分解剤の例を示す。
スプレー缶を構成する耐圧容器１に水系で製造された光触媒と噴射液としてのジメチルエーテル（ＤＭＥ）との混合液を内容物６として充填してある。
耐圧容器内にはチューブ５を配設し、チューブ５の先がノズル４につながり、途中に弁３ａを有する。
噴霧ボタン３を押すとこの弁３ａが開き、ノズル４から内容物がスプレーされる。
また、使用しないときはキャップ２を装着する。
FIG. 1 shows an example of a spray can type disinfectant according to the present invention.
A pressure-resistant container 1 constituting a spray can is filled with a mixed liquid of a photocatalyst manufactured in an aqueous system and dimethyl ether (DME) as a jetting liquid as a content 6.
A tube 5 is disposed in the pressure vessel, the tip of the tube 5 is connected to the nozzle 4, and a valve 3a is provided in the middle.
When the spray button 3 is pressed, the valve 3a is opened and the contents are sprayed from the nozzle 4.
When not in use, the cap 2 is attached.
光触媒を含有する水系原液とＤＭＥとの混合割合は、スプレー圧、スプレー量等を考慮して設定される。
例えば、本実施例では、上記原液とＤＭＥとを質量にて６０：４０の割合で混合した。
混合割合は概ね原液：ＤＭＥ＝７０：３０〜５０：５０の範囲である。
The mixing ratio of the aqueous stock solution containing the photocatalyst and DME is set in consideration of the spray pressure, the spray amount, and the like.
For example, in this example, the stock solution and DME were mixed in a mass ratio of 60:40.
The mixing ratio is generally in the range of stock solution: DME = 70: 30 to 50:50.
水系で製造された光触媒としては特許文献１，２に開示する酸化チタンの結晶粒子を用いることができる。
例えば、鑓型形状の結晶粒子からなる酸化チタン原液は、水系で水酸化チタンの沈殿物を生成させ、これを水に懸濁させた状態で過酸化水素水を加えることでペルオキソ基で修飾されたＯＨ基含有酸化チタンを得ることができる。
また、これにイルメナイト鉱石の硫酸反応液から硫酸塩を回収し、これを加水分解し、得られた水酸化チタンを焼成したＯＨ基含有球型酸化チタンの微粒子を混合してもよい。
これらの水系で製造された酸化チタンはＯＨ基を有しているのでＤＭＥとの親和性が高く、スプレー缶にすることが可能になる。
As the photocatalyst produced in an aqueous system, crystal particles of titanium oxide disclosed in Patent Documents 1 and 2 can be used.
For example, a titanium oxide stock solution composed of bowl-shaped crystal particles is modified with a peroxo group by forming a precipitate of titanium hydroxide in an aqueous system and adding hydrogen peroxide water in a state where it is suspended in water. An OH group-containing titanium oxide can be obtained.
Further, OH group-containing spherical titanium oxide fine particles obtained by recovering sulfate from a sulfuric acid reaction solution of ilmenite ore, hydrolyzing the sulfate, and firing the obtained titanium hydroxide may be mixed.
Since these titanium oxides produced in an aqueous system have OH groups, they have a high affinity with DME and can be made into spray cans.
