It is.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the sterilization pad and the sterilization pad manufacturing method according to an embodiment of the present invention.

First, a sterilization pad according to an embodiment of the present invention will be described.

Sterilization pad 100 of the present invention includes a microcapsules 110 and polyurethane foam 120 containing the propolis extract. Here, the microcapsules 110 are provided on the surface of the polyurethane foam 120.

As shown in FIG. 2, the microcapsules 110 are composed of a silica gel 111 formed by a sol-gel reaction and a sterilizing material 115 filled in the silica gel 111.

In one embodiment of the present invention, the silica gel 111 forming the appearance of the microcapsules 110 is a material in which the porous pores 113 are formed, and reaches a predetermined temperature (for example, 40 ℃ to 50 ℃), sterilization The porous pores 113 are enlarged so that the material 115 is discharged to the outside.

The silica gel 111 has a particle diameter of 0.8 μm to 2 μm and a hollow capsule shape, but is not limited thereto. However, forming the particle size of the microcapsules 110 less than 0.8 μm is difficult to control in the process, and the amount of the sterilizing substance 115 (propolis extract) is reduced, which may lower the sterilization effect, and also the microcapsules 110 This is because the supporting phenomenon of the microcapsules 110 in the polyurethane foam 120 may not be well formed when the particle diameter of the sheet exceeds 2 μm.

In one embodiment of the present invention, the content of the microcapsules 110 is not particularly limited, but is preferably included in about 3% to 20% by weight of the total weight of the sterilization pad 100. This is because when the content of the microcapsules 110 is less than 3% by weight, the sterilization effect may be low, and when the amount of the microcapsules 110 is greater than 20% by weight, the sterilization effect may not be increased any more, which may be inefficient in terms of cost. . On the other hand, the polyurethane foam 120 of the remaining components of the sterilization pad 100 is preferably included in the remaining amount, that is, about 80% to 97% by weight.

In one embodiment of the present invention, the silica gel 111 has a characteristic of slowly releasing the sterilizing material 115, which is an internal material at normal temperature at normal temperature, and thus when heated to 40 ℃ to 50 ℃ As shown at the start of the release of Fig. 2, release to the outside is facilitated.

Here, the material containing the propolis extract may be used as the sterilizing material 115. Specifically, the microcapsule 110 is a mixed solution containing a propolis extract, tetraethyl orthosilicate (TEOS) and partially hydrolyzed silane compound, having an opposite polarity to the propolis extract while acid or alkali is dissolved. It is preferably produced by emulsifying and dispersing in solution to cause a sol-gel reaction at the interface to incorporate the propolis extract.

On the other hand, in one embodiment of the present invention, the polyurethane foam 120 is composed of voids (in other words, void cells) has a structure that is easy to collect the microcapsules 110 into the voids.

In one embodiment of the invention, the polyurethane foam 120, when the sterilization pad 100 of the present invention is used for toilet seat sterilization with a sterilization pad, about 10㎛ to 500㎛, preferably about It is preferred to have a pore cell size of 10 μm to 120 μm, more preferably a pore cell size of about 80 μm to 120 μm.

However, when the pore cell size of the polyurethane foam 120 is less than 10 μm, the microcapsules 110 may not be supported in the pores, so that the sterilization effect may be lowered, and the pore cell of the polyurethane foam 120 may be reduced. If the size of more than 500㎛ microcapsules 110 are supported in the pores, but may be leaked again may reduce the sterilization effect.

When the pore cell size of the polyurethane foam 120 is 80 μm or more, the microcapsules 110 are easily supported by the pore cell of the polyurethane foam 120, and the pore cell of the polyurethane foam 120 is formed. When the size is 120 μm or less, the microcapsules 110 supported on the polyurethane foam 120 are not easily separated, thereby improving sterilization effect.

One embodiment of the present invention by adjusting the size of the pore cell of the polyurethane foam 120 used in the sterilization pad 100 as described above, the content of the microcapsules 110 coated on the polyurethane foam 120 By adjusting, the sterilizing life of the sterilizing material 115 contained in the microcapsules 110 can be adjusted.

On the other hand, if the polyurethane foam 120 according to an embodiment of the present invention is too thick, it does not appear in appearance, if too thin, the content of the microcapsules 110 accommodated with the sterilizing material 115 is reduced because the sterilizing power is weakened , But preferably has a thickness within the range of 0.5mm to 5mm, but is not necessarily limited thereto.

Meanwhile, an embodiment of the present invention has been described as an example of the polyurethane foam 120 as a material to which the microcapsules 110 are coated, but is not necessarily limited thereto. ) Is formed so that the microcapsules can be attached.

Hereinafter, a sterilization pad manufacturing method according to an embodiment of the present invention will be described.

Method for producing a sterilization pad 100 of the present invention using the propolis extract to produce a propolis extract containing microcapsules 110 by a sol-gel reaction method; And coating the surface of the polyurethane foam 120 with the propolis extract-containing microcapsules 110.

First, the propolis extract can be obtained using a conventional extraction method for extracting the active ingredient from natural substances. For example, a method by vacuum ultrasonic extraction after boiling water specific gravity separation, a supercritical fluid extraction method, a water vapor extraction method or a solvent extraction method may be mentioned.

Preferably, the propolis extract may be made by vacuum ultrasonic extraction after removing beeswax by boiling water specific gravity separation method from the honeycomb. Propolis extracts may also be purchased commercially and used. Preferably, the propolis extract is preferably extracted by vacuum ultrasonic extraction after removing beeswax from the honeycomb by boiling specific gravity separation method.

Such propolis extracts are microencapsulated, and the microcapsules 110 can be prepared by generally known microencapsulation processes. For example, the microcapsules 110 may be prepared by the sol-gel reaction method disclosed in Korean Patent Publication No. 2003-0064126, but is not limited thereto.

For example, the microcapsules 110 are mixed with a propolis extract, tetraethyl orthosilicate (TEOS), and a partially hydrolyzed silane compound, and have polarity opposite to that of the propolis extract while acid or alkali is dissolved. It can be prepared by emulsifying and dispersing in a solution having a sol-gel reaction at the interface to incorporate the propolis extract.

The propolis extract-containing microcapsules 110 produced by such a microencapsulation process do not specifically limit the particle size, but as described above, preferably have a particle diameter of about 0.8 μm to 2 μm.

Next, the propolis extract-containing microcapsules 110 are coated on the surface of the polyurethane foam 120.

The microcapsules 110 may be coated on the polyurethane foam 120 by commonly known spraying or impregnation methods. This is, in one embodiment, a pretreatment step of expanding the pore size in the polyurethane foam 120 by spraying an alcohol, such as ethanol, containing an expanding agent on the polyurethane foam 120; Spraying or impregnating the propolis extract-containing microcapsules 110 on a pretreated polyurethane foam 120; And drying the sprayed or impregnated polyurethane foam 120.

In the pretreatment, the alcohol may contain not only an expanding agent but also a curing agent as necessary. As such, when the polyurethane foam 120 is treated with an alcohol such as ethanol, the alcohol and the polyurethane react with the foam to expand the void cell of the polyurethane foam 120. In this way, expanding the pore cell of the polyurethane foam 120 makes it easier to capture the microcapsules 110 into the pore cell.

In fact, a photo of the fabric sheet of the polyurethane foam 120 used in the embodiment of the present invention is shown in Figure 3 before and after the pre-treatment (in the left side of the first photo in Figure 3 is 10,000 of the fabric sheet) Magnification photo, the rest is the actual size of the fabric sheet.)

After performing the pretreatment, the microcapsules 110 are incorporated into the polyurethane pore cells by spraying or impregnating the microcapsules 110 into the polyurethane foam 120 having the expanded pore cells.

Subsequently, drying it restores the expanded pore cell back to its original size. At this time, the drying temperature conditions are not particularly limited, but preferably drying at 20-80 ° C. is advantageous for restoring the pore cell to its original state.

When the sterilization pad 100 of the present invention is manufactured for toilet seat sterilization with a sterilization pad, the polyurethane foam 120 has a pore cell size of 10 μm to 120 μm, more preferably 80 μm to 120 μm. It is desirable to have a void cell size. The polyurethane foam 120 is composed of a pore cell as described above has a structure that is easy to collect the microcapsules 110 into the pore cell.

If the pore cell size of the polyurethane foam 120 is less than 10 μm, the microcapsules 110 may not be supported in the pores, so that the sterilization effect may be reduced, and the pore cell of the polyurethane foam 120 may be reduced. If the size of more than 120㎛ microcapsules 110 is coated in the pores, but may be leaked again because the sterilization effect is lowered is not preferred.

Sterilization pad 100 of the present invention is used for sterilization of the toilet seat with a sterilization pad, in particular can be used as a toilet seat cover with a sterilization pad of the toilet seat with a bidet, but is not limited to this useful for various uses such as filters of air cleaners Can be used.

When the sterilization pad 100 of the present invention is used for toilet seat sterilization with a sterilization pad, the pad is used to be attached to the toilet seat cover having a sterilization pad of the toilet with a bidet installed thereon and attached to the toilet seat cover having a sterilization pad. When the pad is closed, the sterilizing material 115 in the sterilizing pad 100 is activated to activate the toilet seat with the sterilizing pad by activating the toilet seat heating function or the drying function with the sterilizing pad. It will be sterilized.

Alternatively, the sterilization pad 100 of the present invention may be used as a filter of an air cleaner in the form of a nonwoven fabric and a polyurethane foam. The sterilizing material 115 coated on the nonwoven fabric and polyurethane foam is spontaneously released through the holes in the spherical surface or by the strong wind of the fan.

Therefore, the sterilization pad 100 is a kind of an air cleaning filter and has a function of killing mold and the like in the dust filtered by the nonwoven fabric and the polyurethane foam, as well as sterilizing mold or bacteria in the dust stacked on the HEPA filter. do.
