[Embodiment] An embodiment of the present invention will be described in detail below based on the drawings.

The ceramic coating agent 3 constituting the present invention comprises ultrafine metal oxide particles having binding properties, far-infrared radiation, and antistatic properties, resin-based polymers having binding properties, antibacterial properties, and gas adsorption properties. This is a ceramic coating agent consisting of an inorganic filler having gas-decomposable properties, and its components and functions are as follows.

The components of the coating agent 3 constituting the present invention are silicon dioxide (S 102), aluminum oxide (Aisos),
, titanium oxide (T iO2), modified polypropylene,
Metal ions consisting of copper ions or silver ions (Ag''),
Zeolite (Ca0.2 A I xO3.5SiOa
).

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 ceramic-based coating agent 3 of the present invention having the above-mentioned components and functions is formed into a powder and then converted into a liquid form as a one-component ink that cures at room temperature using a solvent such as alcohol. The rubber body 1 of the present invention is formed by coating the surface 2 of the rubber body 1 . This is shown in FIG. 9, and the rubber body 1 of the present invention is formed of two layers: the ceramic coating agent 3 and the rubber body 1.

Further, the present invention is not limited to the above embodiments, and the back surface of the rubber body or both the front and back surfaces of the rubber body 1 may be coated with a roll or spray coated. In that case, coating may be performed simultaneously during dyeing, printing, etc. steps.

Since the coating agent 3 constituting 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 rubber body 1. It can be coated and there is no risk of peeling 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.

To explain the antibacterial properties of the coating agent 3 of the present invention, the metal ions consisting of copper ions or silver ions contained in the coating agent 3 are trace metals that constantly generate trace amounts of ozone (03) over a long period of time. It has a great antibacterial (killing) effect against all kinds of pathogenic bacteria, and is effective for 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, it has antibacterial properties, so when used as a packaging container for fresh foods, etc., it can also exhibit a freshness-preserving function.

Furthermore, when a coating film containing metal ions is formed on the rubber body 1 using the coating agent 3 of the present invention, which has strong adhesive strength and a small covering power compared to resin, the rubber body 1 has a constant bactericidal property over a long period of time. It is possible.

(3) Results Table 1 Next, to explain the gas adsorption effect of the present invention, when the coating agent 3 constituting the present invention is coated on the rubber body 1, the porosity of the coating film formed by the zeolite constituting the coating agent 3 increases. The textured surface absorbs gas (odor),
Ozone generated from metal ions consisting of copper or silver ions immediately decomposes this.

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 constituting 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.

Next, the effect of far-infrared radiation according to the present invention will be explained below.

Far-infrared rays are electromagnetic waves with wavelengths of 4 to 1.000 microns and have the property of directly reaching objects without being affected by air. Furthermore, most organic materials such as human skin have a high absorption rate (and emissivity) of far-infrared rays, and also have high thermal conductivity, so when far-infrared rays are received, thermal energy reaches deep into the body.

Due to the action of silicon dioxide contained in the ceramic coating agent 3 of the present invention, the emissivity in the effective wavelength range of 4 to 15 microns is reduced to 0.00, as shown in FIG. 9 or more, making it an ideal far-infrared radiator.

Therefore, the rubber body 1 of the present invention can improve the heat retention effect. At the same time, it can also improve hygroscopicity and breathability.

To explain the antistatic effect of the present invention, the ultrafine particulate aluminum oxide contained in the ceramic coating agent 3 constituting the present invention has a strong property of charging the stopper, and the negatively charged rubber body This is the opposite of the electrostatic charge in No. 1, and the generation of electrostatic charges can be prevented.

Ultrafine aluminum oxide particles have a strong property of charging the stopper in contrast to other solid components contained in the ceramic coating agent 3 constituting the above-mentioned invention, and the ultrafine aluminum oxide has a strong property of charging the stopper. Among them, it forms stable aggregates with solid components and has the effect of stabilizing the composition for a long period of time.

Further, the rubber body 1 of the present invention retains the texture of a conventional rubber body,
There is almost no difference from the conventional method.

In addition, the rubber body of the present invention has excellent deodorizing and deodorizing properties when used in rubber products in various fields such as agricultural, industrial, fishing, civil engineering and construction, consumer products such as daily necessities, and packaging. Therefore, its range of use is extremely wide.

Furthermore, since the rubber body of the present invention has excellent antibacterial (sterilizing) properties, for example, when used in daily necessities, building interior materials, etc., various germs such as mites, lice, mold, etc. It does not breed and can be used cleanly and comfortably.

At the same time, it has excellent sterilizing power, so when used in food products, packaging containers, etc., it can maintain the freshness of perishable foods.

In addition, due to its excellent deodorizing and deodorizing properties, it is able to deodorize the odor of the rubber body itself, making it an effective product in fields where it could not be used due to the unique odor of rubber. It can be used as a rubber product. In addition, since the present invention has deodorizing properties, when used for rubber packaging containers, footwear, etc., it can effectively remove foreign odors from stored items and from inside footwear. It is something that can be done.

Furthermore, since the present invention is an ideal far-infrared radiator, it can improve the heat retention effect of various rubber products, and at the same time, it has antistatic properties, so it can prevent various rubber products from being charged.
