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 constituting the present invention having the above-mentioned components and functions is a one-component ink that cures at room temperature by forming a powder and using a solvent such as alcohol, and is applied to metals such as steel plates. The metal 1 of the present invention is formed by coating the surface 2 of the metal 1 . This is shown in FIG. 9, and the metal of the present invention is formed of two layers: a ceramic coating agent 3 and a metal 1.

40g is appropriate, but in the case of metal 1, usually 20g
/rd is sufficient to obtain the desired effect.

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 it strongly adheres to the metal 1 and coats it. There is no risk of 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.

Therefore, by coating the entire metal with the coating agent 3 of the present invention, a metal having acid antifreeze resistance can be obtained.

To explain the anti-bactericidal properties of the coating agent 3 constituting the present invention, the metal ions consisting of copper ions or silver ions contained in the coating agent 3 contain a trace amount of ozone (
It has a trace metal effect that constantly generates 03) over a long period of time, and has a great antibacterial (sterilizing) effect against all kinds of pathogenic bacteria, and is effective over a long period of time.

In other words, due to the catalytic action of metal ions consisting of copper ions or silver ions, a portion of oxygen is converted to active oxygen, which exhibits sterilizing properties against microorganisms, such as general pathogens, bacteria,
Effective against microorganisms such as mold and algae, mites, and lice.

At the same time, since it has antibacterial properties, when used as packaging containers for fresh foods, etc., it can also exhibit a freshness-preserving function.

In addition, when a coating film containing metal ions is formed on metal 1 using coating agent 3 of the present invention, which has strong adhesive strength and has a smaller covering power than resin, metal 1 is constantly sterilized for a long period of time. be.

Measure after incubation for an hour.

(3) Results Next, to explain the gas adsorption effect of the present invention, when the coating agent 3 of the present invention is coated on the metal 1, the porous surface of the coating formed by the zeolite constituting the coating agent 3 absorbs gas. ozone, which is generated from metal ions such as copper or silver ions, immediately decomposes it.

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 coating agent 3 of the present invention adsorbs all kinds of odors and decomposes them with metal ions consisting of copper ions or silver ions, so its gas (odor) decomposition ability does not deteriorate over a long period of time.

In particular, due to the action of titanium oxide, the deodorizing power can be maintained for a long time without deteriorating.
