Further, the present invention is characterized by the technical construction of a solid-state eco-friendly deodorizing and germicidal composition manufacturing method, further comprising the step of adsorbing the eco-friendly deodorizing and sterilizing composition onto a porous zeolite.
Next, the eco-friendly deodorizing and disinfecting composition according to the present invention will be described in detail.
However, the embodiments of the present invention can be modified into various forms, and the scope of the present invention is not construed as being limited to the embodiments described below. The embodiments of the present invention are provided so that those skilled in the art can understand the present invention.
First, the eco-friendly deodorizing and disinfecting composition according to the present invention comprises stabilized chlorine dioxide (S-ClO 2 ), sodium carbonate (Na 2 CO 3 ), sodium bicarbonate (NaHCO 3 ), sodium dihydrogen phosphate (NaH 2 PO 4 ) .
The composition of the present invention comprises stabilized chlorine dioxide as a main component and sodium dihydrogen phosphate and sodium bicarbonate, including sodium carbonate and citric acid, are added as a subcomponent to reinforce mutual deodorization and sterilization power and to achieve hygroscopic power.
The stabilized chlorine dioxide is a substance formed based on the components of chlorine dioxide. The stabilized chlorine dioxide compensates for the defects of chlorine dioxide only and keeps its stable state while gradually changing the environment such as temperature and pH and releasing chlorine dioxide slowly It is a controlled substance. That is, the stabilized chlorine dioxide is stabilized so as not to explode the explosive chlorine dioxide gas.
In general, chlorine dioxide (ClO 2 ) is a strong oxidizing agent that dissolves well in water and is volatile. It has explosive decomposition by heat and strong oxidation and bleaching action. Therefore, it is difficult to concentrate at a high concentration and diluted to a concentration of about 8 to 10%. In addition, chlorine dioxide has an optical decomposition effect that is easily decomposed by ultraviolet rays in gas, but it is not hydrolyzed in water and oxidizes or destroys the substances causing odor (for example, ammonia, hydrogen sulfide, mercaptan, phenol) The chlorine compound reacts with the organic material during the sterilization process to produce carcinogens such as trihalomethanes, but the chlorine dioxide does not produce carcinogens at all.
As the stabilized chlorine dioxide, a chlorine dioxide concentration of 1 to 20% by weight is used. Preferably, a concentration of 8 to 13% by weight is used.
As described above, when the stabilized chlorine dioxide is used, it is possible to produce a composition having high deodorization efficiency without generating resistance or immunity as a bactericide because it is sterilized by strong oxidizing action.
Said carbonate, sodium bicarbonate, and citric acid each have a purity of 90 wt% or more. That is, the above carbonate, sodium bicarbonate and citric acid are respectively added by adding 90 to 100% by weight of a material.
In the above, sodium carbonate has an alkaline property and is excellent in the removal of malodor and cleaning power, and strong hygroscopicity.
The hydrogen dihydrogenphosphate is used by adding a raw material having a purity of 90%.
The present invention also provides an environmentally friendly deodorizing and disinfecting composition in liquid form using the above-mentioned environmentally friendly deodorizing and germicidal composition. That is, the liquid environment-friendly deodorizing and disinfection composition is composed of stabilized chlorine dioxide (concentration 1 to 20 wt%), sodium carbonate (purity 90% or more), sodium bicarbonate (purity 90% or more), sodium dihydrogenphosphate (Purity of 90% or more).
The stabilized chlorine dioxide is added in an amount of 10 to 90% by weight. By weight, preferably 30 to 60% by weight. That is, when the amount of the stabilized chlorine dioxide is less than 10% by weight, the deodorizing and sterilizing power is lowered, and when it exceeds 90% by weight, the raw material cost is high.
1 to 30% by weight of sodium carbonate, 1 to 30% by weight of sodium bicarbonate, 1 to 30% by weight of sodium dihydrogenphosphate and 0.01 to 0.1% by weight of citric acid are gradually added to 10 to 90% by weight of the stabilized chlorine dioxide, The stabilized chlorine dioxide is maintained at a pH of 6-8.

That is, the solid-state eco-friendly deodorizing and sterilizing composition is capable of deodorizing or sterilizing the environment while spreading the eco-friendly deodorizing and sterilizing composition adsorbed on the porous zeolite.
The zeolite selectively adsorbs the unsaturated material by the action of cations in its crystal structure, so that the eco-friendly deodorizing and germicidal composition is adsorbed.
Further, since the zeolite has a pore size of a certain size, it selectively adsorbs smaller molecules. The porous zeolite adsorbs the eco-friendly deodorizing and sterilizing composition made of smaller molecules.
Since the zeolite contains exchangeable cations in the crystal structure, it easily exchanges freely with other cations. That is, the zeolite exchanges with the adsorbed environmentally-friendly deodorizing and sterilizing composition, and removes harmful substances in the surrounding environment and exerts the effect of deodorization.
It is preferable that the application specific gravity of the solid-phase eco-friendly deodorizing and sterilizing composition is 1: 1 relative to the air of the space to be applied.
In order to use the solid environment-friendly deodorizing and sterilizing composition, it is preferable to penetrate a predetermined hole so that the composition component can easily diffuse and diffuse.

In order to form the eco-friendly deodorizing and sterilizing composition, all of the prepared raw materials are mixed and formed. That is, the stabilized chlorine dioxide is mixed with sodium carbonate, sodium bicarbonate, sodium dihydrogenphosphate, and citric acid in the order of continuously stirring.
The composition of the composition is 1 to 30% by weight of sodium carbonate, 1 to 30% by weight of sodium bicarbonate, 1 to 30% by weight of sodium dihydrogenphosphate and 0.01 to 0.1% by weight of citric acid in 10 to 90% by weight of stabilized chlorine dioxide To be established.

When the eco-friendly deodorizing and germicidal composition is adsorbed on the zeolite, it is preferable that the adsorption is carried out for a sufficient time until the adsorption amount inside the zeolite is saturated and no further adsorption is carried out.
In this case, the adsorption process can be carried out using various types of adsorbers which are used to adsorb the adsorbent on the adsorbent.
That is, according to the eco-friendly deodorizing and disinfecting composition and the method for producing the same according to the present invention, it is possible to prevent the occurrence of resistance or immunity as a disinfectant and prevent damage due to various diseases, It is possible to keep the surrounding environment clean.
In addition, since the present invention is applied to farmhouse facilities, the medicines do not react with natural saccharides and do not damage the fiber. Therefore, it is possible to protect various cultivated crops, improve the quality of the crops, It is possible to maintain the safety and health of the users and to increase the yield of crops, thereby contributing to the improvement of the income of the farmers, while preserving the environment.
In addition, the present invention is capable of preventing persistence and generation of carcinogenic substances in the human body by discharging into oxygen and water during the reaction by the action of the composition.
