Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to install a slime remover composition and a slime remover for installing a slime due to various bacteria and molds, such as a drainage port of a kitchen sink, for removing slime. It is about the method.

[0002]

2. Description of the Related Art Food waste and the like are attached to the drainage outlet of a kitchen sink, and proper water is present, so that various bacteria and molds can easily propagate. When such germs and mold propagate, slime occurs near the drain outlet and inside the pipes.
Such sliminess may be difficult to remove by simply physically rubbing it, and it is difficult for a brush or the like to reach the inside of the pipe or the like, and it is difficult to physically remove the slime component.

As a method for removing such slime components,
It is possible to use a chlorine-based oxidizer or hydrogen peroxide-based oxidizer to chemically decompose and remove bacteria and mold, but these oxides are dangerous substances and should be handled with care. Therefore, it is problematic for housewives in general households to use it daily.

Sodium percarbonate is known as an oxidizing agent which is less dangerous than the above-mentioned oxidizing agents and has a mild decomposition reaction. Since this sodium percarbonate generates oxygen when it reacts with water, this sodium percarbonate is installed near the drainage port where water flows, and oxygen is gradually generated to chemically remove bacteria and mold. A method of disassembling and removing slimy components can be considered.

[0005]

However, since such a sodium percarbonate powder starts to react immediately when it comes into contact with water, it is not possible to simply spray the sodium percarbonate powder near the drain port or in the pipe. The reaction quickly occurs to generate oxygen, which is then flushed with water. Therefore, there arises a problem that the slimming effect cannot be maintained for a long period of time. Although it is said that it is less dangerous than chlorine-based or hydrogen peroxide-based oxidants, it requires careful handling.

An object of the present invention is to provide a slime remover composition using such sodium percarbonate in a more effective manner, which is safer to handle and has a long slime removing effect. It is an object of the present invention to provide a slime remover composition that can be maintained for a period and a method for producing a slime remover.

[0007]

The slime remover composition of the present invention is characterized in that sodium percarbonate coated with a wax-like substance is mixed with an inorganic powder.

Sodium percarbonate in the present invention means a compound generally called sodium percarbonate, which is hydrogen peroxide of sodium carbonate represented by a chemical formula such as NaCO ₃ · 3 / 2H ₂ O _2. It is an adjunct. That is, the term "sodium percarbonate" is used in the present invention as a general term for compounds that generate oxygen by a decomposition reaction from hydrogen peroxide and sodium carbonate as raw materials.

In the present invention, the wax-like substance coated with sodium percarbonate is not particularly limited as long as it is a solid substance or a semi-solid substance at room temperature, a hydrophobic substance or a water-insoluble or slightly water-soluble substance. Specifically, commonly used waxes such as paraffin wax and polyolefin oligomer can be used, and may be natural wax or synthetic wax. Usually, paraffin wax having a melting temperature of about 47 to 69 ° C., more preferably about 55 to 69 ° C. is preferably used.

In the present invention, the ratio of sodium percarbonate to wax-like substance is preferably 70 to 98% by weight of sodium percarbonate and 30 to 2% by weight of waxy substance, more preferably 80 to 91% by weight of sodium percarbonate. , Wax-like substance 20-9% by weight, more preferably sodium percarbonate 83-88% by weight, wax-like substance 17-12
% By weight. When the amount of the wax-like substance is larger than that of sodium percarbonate, the water repellency becomes strong, so that the reaction of sodium percarbonate becomes slow and, in some cases, does not react. Moreover, a large amount of residue remains. When the amount of the wax-like substance is smaller than that of sodium percarbonate, the water repellency becomes weak and the sodium percarbonate reacts rapidly so that the slimming effect cannot be maintained for a long time.

In the present invention, the ratio of the wax-like substance-coated sodium percarbonate to the inorganic powder is
Sodium percarbonate coated with waxy material 2
0 to 80% by weight, more preferably 40 to 60% by weight,
The range is more preferably 45 to 55% by weight, and therefore the range of 80 to 20% by weight of the inorganic powder is preferable, more preferably 60 to 40% by weight, further preferably 55 to 45% by weight. When the amount of the inorganic powder is large, the cleaning effect of the pipes and the like is good, but the slimming effect tends to be small. Also, if the amount of the inorganic powder is small, the slime removing effect is improved, but the sustainability of the effect is poor,
The cleaning effect of piping etc. will be reduced.

The inorganic powder used in the present invention is preferably one which is poorly soluble in water, such as calcium carbonate, calcium-magnesium carbonate and carbonates such as magnesium carbonate, aluminum hydroxide, magnesium hydroxide and the like. Sulfates and sulfites such as hydroxide, calcium sulfate, calcium sulfite and barium sulfate, oxides such as iron oxide, titanium oxide and zinc oxide, talc, mica, kaolin clay, calcined clay, bentonite, pyrophyllite , Mineral powders such as attapulgite, nepheline / cyanite, diatomaceous earth, zeolite, sericite, calcium silicate, aluminum silicate, and glass powder, and silicate powders, silica gel, silica, and silicon oxides and oxides such as alumina. Ceramic powder such as aluminum . You may use these inorganic powders in mixture of 2 or more types. Among these, calcium carbonate is most preferable in consideration of the stability of sodium percarbonate and the like and the influence on the environment.

Considering the cleaning property of the calcium carbonate powder by polishing, calcium carbonate powder having a relatively large particle size is preferable. As such calcium carbonate powder,
Examples include heavy calcium carbonate powder obtained by crushing and classifying limestone.

The slime remover composition of the present invention preferably contains a water-soluble binder. When such a water-soluble binder is used, when it comes into contact with water, the water-soluble binder is eluted into water, whereby the surface is partially collapsed and the inorganic powder is released. Due to the release of the inorganic powder, the inside of the pipe is physically rubbed and the inside of the pipe is washed. The amount of the water-soluble binder is 2 with respect to 100 parts by weight of the inorganic powder.
˜15 parts by weight is preferable, and more preferably 4 to 10 parts by weight. Specific examples of such a water-soluble binder include, for example, polyethylene glycol, polypropylene glycol, polypropylene glycol addition polymer (polyoxyethylene polyoxypropylene block polymer, etc.), polyoxyethylene alkyl ethers,
Mention may be made of synthetic and natural water-soluble polymers such as polyvinyl alcohol, sodium polyacrylate, sodium alginate, gelatin and the like.

If necessary, other components can be added to the slime remover composition of the present invention, for example, a deodorant, an antibacterial agent, and a bactericide. As the antibacterial agent and the bactericidal agent, it is preferable to use those other than chlorine.

The method for producing a slime remover of the present invention is a method for producing a slime remover comprising the above slime remover composition of the present invention. The manufacturing method of the present invention is
The method comprises the steps of adding a wax-like substance to sodium percarbonate and coating the mixture to form beads, and mixing the beads of inorganic percarbonate with the beads of inorganic powder and press-molding the mixture.

The coating of sodium percarbonate with a wax-like substance is, for example, a powder of sodium percarbonate,
It can be carried out by a method in which the wax-like substance is heated to a temperature higher than the melting temperature of the wax-like substance while being stirred, stirred for a predetermined time, and then cooled under stirring to bead. The diameter of the sodium percarbonate beads is preferably about 0.1 to 5 mm, more preferably 0.5 to 3 mm. The heating of the wax-like substance with stirring is performed at a temperature of about 70 to 90 ° C., preferably 75.
The temperature is preferably about -80 ° C. At temperatures above 80 ° C, decomposition of sodium percarbonate begins,
The upper limit of the preferable heating temperature range is set to 90 ° C. because even if sodium percarbonate is decomposed to some extent, it does not cause much problems in a short time. The lower limit of the heating temperature range is set to 70 ° C. because when paraffin having a melting point of 47 ° C. is used as a wax-like substance, if the heating temperature is lower than this range, the coating may not be successful.

The mixture of sodium percarbonate and the wax-like substance can be stirred in a vessel equipped with a stirrer such as a planetary mixer or a kneader, and it is preferable to stir at a low speed of 500 rpm or less.

In the production method of the present invention, the bead of sodium percarbonate thus produced is mixed with the bead of the inorganic powder, and the mixture is press-molded to produce the slime remover. A metal soap such as calcium stearate is preferably added to such a mixture as a release agent. The amount to be added is preferably 1 to 10 parts by weight, more preferably 2 parts by weight, based on 100 parts by weight of the total bead of sodium percarbonate and the bead of inorganic powder.
~ 6 parts by weight.

In the production method of the present invention, the bead of the inorganic powder is preferably granulated by adding a water-soluble binder to the inorganic powder with stirring.
Such a water-soluble binder functions as a binder for the inorganic powder and, as described above, is dissolved in water by contact with water and partially disintegrates to release the inorganic powder. As described above, the amount of the water-soluble binder is preferably 2 to 15 parts by weight, more preferably 4 to 10 parts by weight, based on 100 parts by weight of the inorganic powder.

The beading of the inorganic powder can be carried out, for example, as follows. For example, while stirring the inorganic powder heated to 60 ° C. to 70 ° C., an aqueous solution containing a water-soluble binder is poured onto the inorganic powder and granulated. The obtained granulated product is dried, for example, at a temperature of 50 to 100 ° C. to obtain an inorganic powder bead.

These components may be added to the slime remover of the present invention by adding a deodorant, an antibacterial agent or a bactericidal agent to such an inorganic powder bead. In such a case, a deodorant, an antibacterial agent, or a bactericidal agent can be added and mixed in the solution of the water-soluble binder. The deodorant content is 100 parts by weight of the inorganic powder beads,
2 to 15 parts by weight is preferable, and 3 to 10 is more preferable.
Parts by weight. The amount of the antibacterial agent and bactericidal agent to be blended is preferably 0.5 to 3 parts by weight, more preferably 1 to 2 parts by weight, based on 100 parts by weight of the inorganic powder beads. By blending such an antibacterial agent and a bactericide, the slimming effect can be further enhanced.

In one of the preferred embodiments according to the present invention, polyethylene glycol (PEG) and polyoxyethylene alkyl ether dibasic acid ester are used as the water-soluble binder. The compounding amount is preferably 90 to 96% by weight of inorganic powder, 0 to 6% by weight of PEG, and 2 to 8% by weight of polyoxyethylene alkyl ether dibasic acid ester, and more preferably 95 to 96% of inorganic powder.
% By weight, 2 to 4% by weight of PEG, and 2 to 6% by weight of polyoxyethylene alkyl ether dibasic acid ester. When using a deodorant, an antibacterial agent, a bactericidal agent, etc., they are added to these components in the above-mentioned blending amounts.

[0024]

In the slime remover composition of the present invention, inorganic powder is mixed with sodium percarbonate coated with a waxy substance. Since the sodium percarbonate is coated with the wax-like substance, the reaction between the sodium percarbonate and water is suppressed, and the sodium percarbonate is gradually decomposed to generate oxygen. Therefore, the slime removing effect can be maintained for a long period of time.

The slime remover composition of the present invention contains an inorganic powder. When a molded product composed of the slime remover composition of the present invention is installed and used at a drainage port of a kitchen sink, etc., the molded product comes into contact with running water, whereby the surface of the molded product is gradually collapsed and inorganic powder is released. Will be done. As a result, the sodium percarbonate existing inside the molded body is gradually exposed on the surface, and the sodium percarbonate exposed on the surface is decomposed by contacting with water to generate oxygen.
Therefore, as the inorganic powder is released and the surface is disintegrated, the sodium percarbonate inside appears on the surface one after another over a long period of time, and the slimming effect of sodium percarbonate continues for a long period of time. Become.

Further, the inorganic powder released into the waste water due to the collapse cleans the inside of the pipe and the like by its polishing action. Therefore, the excellent slimming effect can be maintained for a long time, and the inside of the pipe can be cleaned. In particular,
By using a water-soluble binder as the binder of the slime remover molding, such inorganic powder can be more effectively released. Further, such disintegration of the surface of the slime remover molded article can be controlled by adjusting the type and amount of the water-soluble binder used.

By mixing the deodorant, the antibacterial agent, the bactericidal agent and the like as described above in the slime remover composition, these components are gradually released together with the release of the inorganic powder. Therefore, the effects of these components can be continuously exerted for a long period of time.

Since the slime remover of the present invention contains the inorganic powder, sodium percarbonate is diluted with the inorganic powder and is stabilized. Therefore, handling is improved,
The storability is also improved. Furthermore, by blending inorganic powder,
The press formability with a tableting machine is also improved.
