Description

Deodorant and Method for Producing the Same

The present invention relates to a deodorant and a method for producing the same, and more particularly to a deodorant and a method for producing the deodorant which can decompose by deodorizing the odor causing substances of the urinal.

In general, the odor generated in the toilet mainly occurs in the bottom of the toilet, toilet and drain pipe. Of these, the odor generated in the toilet and the drainage pipe is the main cause of the odor of the toilet, which is the root cause of sediment and various bacteria that are attached to the toilet and the drainage pipe.

Conventional deodorization methods to remove odors include chemical deodorization (masking method), which is supplemented by olfactory smell or fragrance, chemical deodorization method using oxidation, reduction, neutralization, and side reaction, and activated carbon or silica gel. It is roughly classified into a physical adsorption method for collecting by using porous materials such as and a biological deodorization method for disconnecting using microorganisms or enzymes.

However, natural and synthetic fragrances in chemical deodorization have so many kinds that the ingredients are not known, but respiratory and skin troubles are easily caused by toxicity, and the physical adsorption method again increases with increasing temperature and pressure during use. It is easy to regenerate, and the biological deodorization method is not stable due to the large difference in activity depending on the temperature and humidity conditions.

Chemical deodorization is one of the most promising areas for development, but it still has its own limitations in ensuring satisfactory deodorizing power.

The deodorant used in such a deodorant method is to use a deodorant mainly composed of chemical components, the deodorant composed of this chemical component is made of strong acid, harmful to the human body has a problem that is unsafe and causes many side effects in use have.

Deodorants made of conventional chemicals are not only harmful to the human body, but also harmful to the human body in the process of deodorization. The fragrance or naphthalene, which is used to remove odors, causes chemical reactions with ammonia, that is, chemical reaction with NH3, and does not decompose and remove odors by changing the molecular structure of ammonia. Is more indirect than the odor to be decomposed and removed, and thus the user is only an indirect deodorizing function to prevent the user from the odor caused by ammonia.

The prior art has a deodorant using naphthalene or hypochlorite, but it is classified as a carcinogen and harmful to health.

Another deodorant is to use a microorganism, which has a disadvantage that the microorganism does not exert its effect at a temperature of minus 10 ~ 20 ℃.

The deodorant for urinals according to the present invention comprises a first material selected from the group consisting of zeolite, bentonite, elite and activated carbon, and a catalyst mixed with the first material.

The first material and the catalyst are mixed and then put into a mill to grind to a fine powder to obtain a product.

The pulverized fine powder is put into a breathable case or mixed with fine powder with water at an appropriate ratio, and then put into a mold to be molded and cured to produce a specific shape (ball shape or ellipsoid, hexahedral shape).

A method of manufacturing the above-described deodorant for urinal of the present invention will be described with reference to FIG. 1.

Step 1 (S1): Mix 85 to 93% by weight of the first material selected from the group consisting of zeolite, bentonite, elite and activated carbon and 7 to 15% by weight of the catalyst.

Step 2 (S2): The mixture of step 1 and water are mixed to form a dough, but 40 to 50% by weight of the mixture and 50 to 60% by weight of water are mixed.

Step 3 (S3): The dough obtained in step 2 is naturally dried at room temperature.

Step 4 (S4): The dried dough of Step 3 is put in a kiln and heated to be baked to prepare a fired product.

Step 5 (S5): The fired material is crushed to prepare a fine product.

In step 1 (S1), zeolite is a general term for minerals that are aluminum silicate hydrates of alkali and alkaline earth metals. The color is colorless transparent or white translucent. It is also called zeolite and has many kinds, but has high water content, common nature of crystal, acid and so on.

There are many kinds, but the water content is high, and it has the property of crystal and is colorless transparent or white translucent.

The bonds of the atoms are loose in crystal structure, and even though the moisture filling the spaces is released at high heat, the skeleton remains the same, so that other fine particles can be adsorbed.

This property is used as an adsorbent and used as a molecular sieve to separate particulates of different sizes.

Bentonite and illite are minerals that can adsorb water.

The first material is most preferably 85 to 93% by weight. If the first material is 85% by weight or less, the adsorption rate is lowered, and if it is 93% by weight or more, the regeneration capacity is lowered.

Regeneration refers to water washing, and if used after a certain period of time, washing and drying the water may cause the adsorption performance to be exhibited again.

The catalyst is most preferably 7-15% by weight. If the catalyst is 7% by weight or less, the regenerating power is lowered. If the catalyst is 15% by weight or more, the adsorption rate of the first material is reduced.

In addition, the catalyst is most preferably a specific gravity of 2.5 ~ 3.3. The catalyst is preferably a metal material.

As an example, the catalyst is made by mixing one or two or more in the group consisting of magnesium, berium, silicon, aluminum.

Step 3 (S3) is to put the dough in the dryer to dry, but based on 100% by weight of the dough to dry to 12 to 16% by weight or less.

Step 4 (S4) is to put the dried dough in a kiln to form a fired product by heating for 2 to 3 hours at 500 ~ 700 ℃.

Step 5 (S5) is put into the pulverizer obtained in step 4 (S4) and crushed to prepare a fine product.

When the fine product is for the urinal has a particle size of 300 ~ 350 mesh.

The fine powder product has a particle size of 700 ~ 900 mesh for animals.

The fine powder product has a particle size of 800 ~ 3000 mesh for deodorization.

The fine powder has a particle size of 1000 mesh or more when used for spraying.

Thereafter, the fine powder obtained in step 5 (S5) is put into a mold and cured to form a specific shape.

That is, the fine powder product is put into a mold in a state of kneading with water, and then molded and cured to prepare a deodorizing product in the shape of a ball or an ellipsoid or a cube.
