Description of the Related Art For a malodorous gas in the air, an adsorption method using activated carbon, a masking method using another fragrance, or a chemical method of chemically reacting an odorous substance to remove a bad smell or reduce discomfort. Is being done. However, the adsorption method using activated carbon has a problem that the deodorizing performance deteriorates in a short period of time, and it has a drawback that it is likely to cause a fire because it is flammable. In the masking method using other fragrance, the fragrance used may give a new discomfort, and it is not a fundamental solution. As a chemical method of removing a bad smell by a chemical reaction, for example, there is a method of oxidizing and decomposing a bad smell gas with ozone, but this has a problem that excess ozone is harmful to the human body and causes new harm. That is, since it is difficult to control the amount of the chemical substance that reacts stoichiometrically with the foul-smelling gas substance, unnecessary chemical substances remain, and it is difficult to achieve a fundamental solution.

る。The chain-like magnesium silicates such as sepiolite and palygorskite are produced as lumpy natural minerals, and the lumpy minerals are generally used in a crushed granular or fine powder form. If it does, the processing cost is almost zero and the deodorizing performance is high, but there is a problem in terms of breathability and handleability. Further, in order to secure the air permeability, it may be molded into a three-dimensional structure, but in order to adjust the strength of the three-dimensional structure, it is necessary to perform firing at a high temperature of, for example, 700 ° C. or higher, and as a result, chain silicic acid is obtained. There arises a problem that the molecular structure of magnesium is changed and the specific surface area, which is a characteristic required as a catalyst carrier, is reduced.

It is impossible to adsorb these various malodorous substances with a single deodorant, and it is desired to use the deodorant as a composite material. For example, activated carbon has excellent performance in adsorbing thiol-based malodors, and there is a problem in that activated carbon is burned when a molded sepiolite molded product is burned. In addition, when an unburned carrier with excellent air permeability and strength that can withstand handling is attempted to be formed from activated carbon, there is a problem that the binding agent that acts on particle binding blocks the fine pores of activated carbon and halves its adsorption function. is there.

Even so, the fact that the starch syrup state is maintained suggests that the substance mainly composed of metal hydroxide fulfills the binder function.

は低下しない。The expanded structure of the deodorant obtained as described above is such that the surface of the molded product (support) constituted by adhering the activated carbon particles to each other is made into a polymer form with fibrous fine particles (chain magnesium silicate). It seems that the material is composed of a substance and is surrounded by a substance such as a non-woven fabric. Therefore, the strength of the activated carbon carrier is increased, and the adsorption function of activated carbon is not lowered.

異なるが、ほぼ５０％となる。In the method for producing a deodorant of the present invention, when the activated carbon as the carrier is molded, the activated carbon is molded to a strength that can withstand the coating treatment of the suspension, and the activated carbon as a part of the deodorant is polymerized. The substance is applied to supplement the strength of the carrier without reducing the adsorption function of activated carbon. Usually, in the case of molding a carrier having a honeycomb structure, for example, with activated carbon particles having a particle diameter of 0.1 mm or less and a binder, for example, 20 to 30% by weight of an organic binder is blended as a binder and kneaded,
Mold and process. During this kneading and molding, a film of a binder is formed on the surface of the activated carbon particles to block the outside air. The rate of blocking the outside air depends on the binder conditions and the molding conditions, but is about 50%.

割合で配合して使用することができる。According to the invention, the fine powder of chain-like magnesium silicate has a larger specific surface area as the particle size becomes smaller,
It is preferable that the activated carbon be a fine powder having a particle size of 0.1 mm or less, because the fine particles of the metal or the metal complex precipitated by the liquid phase reduction of the metal salt can be well dispersed and supported, and the deodorizing performance and the durability thereof can be improved. On the other hand, the particle size of activated carbon is 0.1 mm
When it exceeds, the adhesion to the carrier and the fixing strength tend to be lowered, which is not preferable. The properties of the chain-like magnesium silicate differ depending on the place of production. For example, in the case of lumpy products, the particle size generated by crushing is 0.1 m.
It is economical to selectively use fine particles of m or less. Also, those produced in a clay-like form, for example, 1-2 μm.

Alternatively, it can be used by mixing with the pulverized fine powder of 0.1 mm or less in a desired ratio.

Is preferably about 1 to 3 liters from the viewpoint of processing workability.
