), titanium oxide (T i OJ , modified polypropylene, metal ions consisting of copper ions or silver ions (Ag”), zeolite (CaO・2A l,to,・5SiO*
).

The functions of each component are as follows: silicon dioxide has the function of a binder and the function of far-infrared radiation.

Aluminum oxide acts as a binder and as an antistatic agent.

In addition to acting as a binder, titanium oxide also acts to prevent deterioration of deodorizing power and promote product durability.

Modified polypropylene acts as a binder.

Metal ions such as copper ions or silver ions have an antibacterial (sterilizing) effect and a gas (odor) decomposing effect.

This metal ion may be either a copper ion or a silver ion.

Zeolite has a gas adsorption effect.

The coating agent 3 of the present invention having the above-mentioned components and functions is formed into a liquid form as a one-component ink that hardens at room temperature by using a solvent such as alcohol on the powder form,
The surface 2 of a permeable porous material 1 made of natural fibers such as cotton and wool, asbestos fibers, synthetic fibers such as rayon and vinylon, glass fibers, metal wool, etc. is coated by spraying processing. A permeable porous body 1 made of various fibers of the invention is formed.

This is shown in FIG. 9, and the permeable porous body 1 made of various fibers of the present invention is formed of two layers: the coating agent 3 and the permeable porous body 1 made of various fibers.

The one shown in FIG. 10 is another embodiment of the present invention, in which the entire permeable porous body l made of various fibers etc. is immersed in a coating agent 3 and squeezed with a roll or the like. By coating in this manner, the coating agent 3 permeates the entire permeable porous body 1 made of various fibers, etc., and the deodorizing effect can be further improved.

The present invention is not limited to the above two examples, but may be coated on the back surface or both the front and back surfaces of the permeable porous body 1 made of various fibers or the like.

Coating methods for the coating agent 3 of the present invention include spray, dip, roll, curtain flow, etc.
In the case of the permeable porous body 1 made of various fibers, etc., spraying, dip coating, etc. are suitable, and in the case of spraying, the appropriate amount of the coating agent 3 to be used is 12 to 40 g per hit; In case of dip, 30 to 40 per d

Usually 20 g/rr? You can get the desired effect before and after.

Since the coating agent 3 of the present invention contains silicon dioxide, aluminum oxide, titanium oxide, and modified polypropylene that function as binders, its bonding and adhesive properties are strong, and the permeable porous body 1 made of various fibers etc. It strongly adheres to and can be coated, and there is no risk of it peeling off during use.

In particular, due to the action of titanium oxide, it has excellent washability, and not only does it not peel off, but the coating agent 3 lasts for a long time without losing its various effects.

Next, the ceramic coating agent of the present invention has anti- (killing) properties.
Regarding fungi, the metal ions such as copper ions or silver ions contained in ceramic coating agents have a trace metal effect that constantly generates trace amounts of ozone (03) over a long period of time, and are effective against all pathogenic bacteria. It has a great antibacterial (sterilizing) effect and is effective for a long period of time.

That is, due to the catalytic action of metal ions consisting of copper ions or silver ions, some oxygen is converted into active oxygen, exhibiting antibacterial properties against microorganisms, and is effective against microorganisms such as common pathogens, bacteria, molds, and algae. Effective against mites, lice, etc.

Furthermore, if a coating film containing metal ions is formed on a permeable porous body 1 made of various fibers using the ceramic coating agent 3 of the present invention, which has strong adhesive strength and has a smaller covering power than resin, it will last for a long time. It is possible to create a permeable porous body made of various types of fibers, etc., which have permeability, constant sterilizing properties, and deodorizing properties.

Due to its sterilizing and deodorizing properties, it can remove odors from hospital rooms and other areas that require deodorization, and can constantly supply fresh air.

(3) Results Table 1 Next, to explain the gas adsorption effect of the permeable porous body 1 made of various fibers, etc. of the present invention, the ceramic coating agent 3 of the present invention was coated on the permeable porous body 1 made of various fibers, etc. In this case, the porous surface of the coating formed by zeolite adsorbs gas (odor), which is immediately decomposed by ozone generated from metal ions consisting of copper or silver ions.

That is, this deodorizing effect is achieved by decomposing odor adsorbed on the active surface of the coating film by active oxygen.

In this way, the ceramic coating agent of the present invention
Since it adsorbs all kinds of odors and decomposes them with metal ions consisting of copper ions or silver ions, its gas (odor) decomposition ability does not deteriorate over a long period of time.
