The present invention relates to a sterilizing and deodorizing inorganic ion solution, a sterilizing and deodorizing composition for preparing the same, and home appliances using the same.

Microorganisms such as germs, fungi, and bacteria are ubiquitous in our living spaces, such as dryers, washing machines, or dishwashers. If these microbes get into our bodies, they can cause life-threatening infections. In particular, in home appliances using water, there is a need for a method capable of securing both sterilizing power against microorganisms and deodorizing power against odor molecules (including both acidic and basic odor molecules).

<1> Home appliances, in particular, home appliances using water such as dryers, stylers, and washing machines require antibacterial, sterilizing, and deodorizing power at the same time by efficiently controlling the adsorption and growth of microorganisms and odor molecules.

Korean Patent Registration No. 10-1875908 ("Prior Patent Document 1") shows a sterilization and deodorization ceramic composition containing waste fossil powder (CaO, MgO), rare earth elements and titanium oxide (TiO ₂ ) in zeolite powder. A method for manufacturing in the shape of a ball is disclosed. However, the ceramic ball manufacturing method disclosed in Prior Patent Document 1 has a problem in that the manufacturing process is complicated and difficult, and technology implementation, production, and manufacturing efficiency are deteriorated. In particular, waste fossil powder is cumbersome in the process because pure oyster shells must be calcined and ground at a high temperature to activate porous particles. In addition, the ceramic ball of Prior Patent Document 1 is a porous material containing a large amount of zeolite, and plays a role in absorbing and adsorbing harmful substances. there is. Furthermore, since there is no clear evidence as to whether actual sterilization and deodorization are expressed in the ceramic ball composition disclosed in Prior Patent Document 1, it is not sufficient to confirm the effect of whether it can be used as a sterilization and deodorization ceramic ball.

In addition, Republic of Korea Patent Application Publication No. 2003-0010820 ("Prior Patent Document 2") discloses a ceramic ball molded into a ball shape by grinding elvan with silver content, specifically, SiO ₂ , Al ₂ O ₃ , A composition in which a bactericidal substance (TiO ₂ , Ag) is added to an alkali component system, which emits anions and exhibits a deodorization rate of 91% and a sterilization effect of 98.7% against Escherichia coli and 97.6% against Pseudomonas aeruginosa. are initiating What is disclosed in Prior Patent Document 2 is a ceramic composition used for water quality improvement such as aquariums and fish farms and sewage wastewater treatment, among which aluminum oxide (Al ₂ O ₃ ), which accounts for the largest proportion, is also used as an antacid and adsorbent . The ceramic ball disclosed in Prior Patent Document 2 shows excellent performance in deodorizing power, but there is a limit in that performance deterioration occurs during repeated use. In addition, iron oxide used in Prior Patent Document 2 has bactericidal performance similar to silver (Ag), but is a substance harmful to the human body. Silver (Ag) has excellent bactericidal power and exhibits effective performance even when used for a long time, but has a disadvantage in that the unit price of the raw material is very high even when only 0.1% by weight is added.

Therefore, the performance of sterilization and deodorization is improved while solving the safety problem of existing sterilization and deodorization ceramic ball materials so as to meet the recent safety and health needs for the human body and the environment, including phenomena such as corona virus infection. There is still a need to develop technologies for disinfecting and deodorizing compositions that, while being well secured, may also have process and cost advantages in manufacturing these materials.

<Composition for preparing sterilizing and deodorizing inorganic ion solution>

The composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention is a mixed composition of a silicate glass composition (composition A) and a borate glass composition (composition B), wherein the silicate glass composition (composition A) contains 40 to 70% by weight of SiO ₂ ; 20 to 50% by weight of at least one of NaO ₂ , K ₂ O and Li ₂ O; and 1 to 25% by weight of at least one of CaO and MgO, and the borate glass composition (composition B) contains 55 to 80% by weight of B ₂ O ₃ ; 10 to 30% by weight of at least one of NaO ₂ , K ₂ O and Li ₂ O; and 5 to 20% by weight of at least one of CaO and MgO.

The composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention is a mixed composition in which composition A and composition B are mixed in a weight ratio of 20:80 to 50:50, and a silicate glass composition and a borate glass composition are mixed in a specific ratio. By using the composition used, the inorganic ion solution prepared using the same can exhibit synergistic effects of sterilization and deodorization.

The composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention does not contain components harmless to the human body and the environment, and since it does not elute harmless heavy metal components when prepared as an inorganic ion solution, it can have human safety and eco-friendliness. .

The composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention is manufactured in a solid form, and when water is added to a home appliance that uses water, an inorganic ion solution having sterilizing and deodorizing performance can be generated. A deodorizing inorganic ion solution can be prepared, and when used in home appliances, etc., it can have a volume advantage due to its solid form.

Hereinafter, the functions of the silicate glass composition (composition A) and the borate glass composition (composition B) included in the composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention will be described in detail.

Composition A is a silicate glass composition containing an alkali component, and in the present invention, it serves to increase the solubility of composition B through pH control, assist in sterilization, and decompose acidic odor molecules. Specifically, the inorganic ion solution eluted using the composition A exhibits alkalinity. On the other hand, a one-step reaction (proportional to the square root of time) in which the pH of water increases and becomes basic by an ion exchange reaction between hydrogen ions (H ⁺ ) of water and alkali ions and alkaline earth ions, which are common elution reactions of glass; and a two-step reaction (proportional to time) in which the network-forming structure is cleaved and eluted by elution of the modified oxide (network) by water showing basicity and hydroxide ion (OH ^- ); it is common to be divided into Composition A The inorganic ion solution eluted using may serve to promote the elution of composition B, which has lower dissolution characteristics than composition A, by omitting the first step reaction. In addition, the optimal growth environment for bacteria is classified into acidophilic (pH<6), neutrophilic (6<pH<8, most bacteria are neutrophilic), and halophilic (8<pH) according to the pH of the environment. Fungi grow best in weakly acidic conditions with a pH of 5≤pH≤6. Therefore, the alkaline solution eluted from composition A can act as a sterilization and sterilization auxiliary component by changing the growth environment of bacteria and fungi. In addition, acidic odor molecules (typically acetic acid; sweat odor) among various odor molecules are decomposed through a neutralization reaction to express deodorizing performance.

Composition B is a borate glass composition containing a large amount of boron, and in the present invention, it can act as a main component of sterilization and sterilization, and plays a role in decomposing basic odor molecules. In the inorganic ion solution from which Composition B is eluted, a large amount of compounds composed of boron (B), oxygen (O), and hydrogen (H) exist, and the shape is a molecule such as B(OH) ₄ ^- , B(OH) ₃ may be in the shape of Since the shape of the molecule is electrically unstable and weakly acidic, it forms an equilibrium state depending on the pH of the solution. The boron compound of the corresponding shape exhibits a germicidal and sterilizing effect through an electrical action. Among various odor molecules, basic odor molecules (typically ammonia; bathroom odor) are decomposed through a neutralization reaction to express deodorizing performance. In this way, in order to sufficiently exhibit sterilization and sterilization performance and decompose basic odor molecules, a glass composition containing a large amount of B ₂ O ₃ needs to be applied. Glass containing a large amount of B ₂ O ₃ is vulnerable to moisture, but has lower elution characteristics than glass containing a large amount of alkali. Therefore, in order to prepare an inorganic ion solution having sterilization and deodorization performance in a short time, it is necessary to improve the dissolution characteristics of composition B by combining it with composition A.

In view of the above, the composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention is a composition for preparing a sterilizing and deodorizing inorganic ion solution that exhibits a synergistic effect of sterilizing and deodorizing power by mixing and using Composition A and Composition B. can be derived

In order to have such a synergistic effect of sterilization and deodorization, it is preferable to mix Composition A and Composition B in a weight ratio of 20:80 to 50:50 in the composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention.

When the content of composition A is less than 20% by weight, the pH of the water cannot be sufficiently raised, so that the single effect of composition A and the composite synergistic effect of the two kinds of mixing of composition A and composition B cannot be expressed, resulting in strong bactericidal and deodorizing effect. There is a problem. When the content of composition A is 50% by weight or more, the pH of water is raised too high, and the consumption of alkali and alkaline earth ions of composition A and boron ions of composition B is fast, making it unsuitable for long-term continuous use.

Hereinafter, the role and content of each component of the silicate glass composition (composition A) and the borate glass composition (composition B) included in the composition for preparing a sterilizing and deodorizing inorganic ion solution according to the present invention will be described.

SiO ₂ is a network-forming oxide, forms a framework structure of glass, and is a key component enabling vitrification by covalent bonding. That is, SiO ₂ is a glass forming agent that enables vitrification, and is a key component that serves as a framework in terms of glass structure.

In the present invention, SiO ₂ is preferably included in a content ratio of 40 to 70% by weight of the total weight of composition A. If the content of SiO ₂ is less than 40% by weight, vitrification is not performed, and the elution rate of alkali increases, causing problems in long-term use and durability. On the other hand, when the content of SiO ₂ exceeds 70% by weight, the water resistance is increased and the elution characteristic is lowered, which is difficult, and the melting temperature for glass production is increased.

B ₂ O ₃ is also a representative network-forming oxide used together with SiO ₂ , and is a key component that forms a framework structure of glass and enables sufficient vitrification by covalent bonding. B ₂ O ₃ exists in the form of 3- or 4-coordinates of BO ₃ and BO ₄ in glass, and is used for lowering the eutectic point of a melt due to its low melting point. In addition, B ₂ O ₃ serves to increase the solubility of rigid components (Al ₂ O ₃ , CuO, etc.) during melting for vitrification, thereby helping to form a homogeneous glass. However, when a certain amount of B ₂ O ₃ is added, problems such as deterioration of water resistance by weakening the bonding structure of glass may occur.

In the present invention, B ₂ O ₃ is preferably included in a content ratio of 55 to 80% by weight of the total weight of composition B. If the content of B ₂ O ₃ is less than 55% by weight, vitrification is not performed, and the elution rate of alkali increases, causing problems in long-term use and sustainability. On the other hand, when the content of B ₂ O ₃ exceeds 80% by weight, it is vulnerable to moisture and forms a hydration layer on the surface in an environment exposed to moisture. There is a problem.

Alkali oxides such as Na ₂ O, K ₂ O, and LiO ₂ are oxides that act as network modifiers for non-crosslinking in the glass composition. Although these components cannot be vitrified alone, they can be vitrified when mixed with network forming agents such as SiO ₂ and B ₂ O ₃ in a certain ratio. Alkaline ions are eluted into water by ion exchange with H ₃ O+ present in water, and when OH ^- ions are formed, the properties of water are activated to alkalinity. An alkaline environment hinders the growth of bacteria and exhibits deodorizing power against acidic odor molecules such as sulfur compounds.

In order to utilize the characteristics of the Na ₂ O, K ₂ O, and LiO ₂ components described above, at least one of Na ₂ O, K ₂ O, and LiO ₂ is SiO ₂ and B ₂ O, which are glass bases of Composition A and Composition B. Considering the characteristics of ₃ , it is preferable to include 20 to 50% by weight in composition A and 10 to 30% by weight in composition B.

Specifically, if at least one of Na ₂ O, K ₂ O, and LiO ₂ is less than 20% by weight in composition A, deodorization performance may be deteriorated and decomposition performance of acidic odor molecules may be insufficient. Conversely, if one or more of Na ₂ O, K ₂ O and LiO ₂ in composition A exceeds 50% by weight, vitrification is not well performed, and non-melting material is generated due to an increase in melting point, resulting in inhomogeneity. .

In addition, if at least one of Na ₂ O, K ₂ O and LiO ₂ is less than 10% by weight in the composition B, durability may increase and dissolution characteristics may deteriorate. Conversely, if at least one of Na ₂ O, K ₂ O and LiO ₂ exceeds 30% by weight, the network modifier may become excessive, causing a problem that vitrification may not occur.

Alkaline earth oxides such as CaO and MgO cannot be vitrified alone, but can be vitrified when mixed with network forming agents such as SiO ₂ and B ₂ O ₃ in a certain ratio. Basically, it is an oxide that acts as a mesh modifier for non-crosslinking in glass. Therefore, it serves to weaken the structure of the glass. However, since the degree of weakening the glass structure is lower than that of alkali ions, when alkaline earth oxides are added to a glass composition containing alkali, the effect of slightly increasing water resistance may be shown. In this patent, alkaline earth oxide is added to express the effect of improving the pH at the time of dissolution and that the dissolution rate is controlled by the water resistance enhancing effect to improve the dissolution homogeneity.

If the content of alkaline earth oxides such as CaO and MgO is too low, the structure cannot be strengthened at the site of the modified oxide, and thus the water resistance that cannot prevent alkali elution may be reduced. Conversely, when the content of alkaline earth oxides such as CaO and MgO is too high, alkaline earth oxides, which are substances that melt at high temperatures, are not sufficiently melted, and thus, they leave the vitrification region, resulting in the formation of unmelted substances.

In order to utilize the characteristics of CaO and MgO components described above, at least one of CaO and MgO is present in composition A and composition B in consideration of the characteristics of SiO ₂ and B ₂ O ₃ , which are glass bases, in an amount of 1 to 25 wt. %, it is preferable to include 5 to 20% by weight in composition B.

Specifically, when one or more of CaO and MgO is less than 1% by weight in the composition A, the sterilization auxiliary performance is lowered and the pH cannot be sufficiently raised. Conversely, if one or more of CaO and MgO exceeds 25% by weight in the composition A, vitrification may not be performed well, and inhomogeneity may occur due to occurrence of unmelted material due to an increase in melting point.

In addition, when the content of at least one of CaO and MgO in composition B is less than 5% by weight, the dissolution homogeneity is lowered and the durability is weakened, which may cause a problem in that the dissolution is not homogeneous. Conversely, if one or more of CaO and MgO exceeds 20% by weight, a non-melted material may occur due to an increase in melting point, resulting in heterogeneity.
