Description

Paint composition mixed with dark catalyst

The present invention relates to a coating composition in which a dark catalyst is mixed. More specifically, for the removal of odors, sterilization, antibacterial, etc., papers, springs, synthetic resins including vinyl cross, woods, cements, stones, metals including iron, and a dark catalyst arriving on soil walls It relates to a mixed paint composition.

Although the conventional coating composition has a certain odor or antibacterial effect by the photocatalytic action of titanium oxide, the effects of the odor or antibacterial in the conventional coating are not sufficient. Moreover, the photocatalyst of titanium oxide in the conventional coating material is characterized by performing a photocatalyst reaction in response to light. As such a coating material, what is known by adding an inorganic binder to titanium oxide which has a photocatalytic effect is already known.

Prior art related to photocatalyst paints is Korean Utility Model Publication No. 2003-31619 (published date: 2003.11.1) "apparatus coated with a paint containing photocatalyst". In addition, Korean Patent Application Publication No. 2003-75888 (published: 2003.9.6) discloses a technology related to a polyurethane foam filter coated with a hydroxyapatite titanium dioxide photocatalyst and a method of manufacturing the same. According to this technique, hydroxyapatite is an inorganic material that does not decompose to titanium dioxide photocatalyst, which is highly stable and uses the ability to selectively adsorb proteins to mix the titanium dioxide photocatalyst with the surface of hydroxyapatite with organic paint. When the surface of the polyurethane foam (polyurethane foam) is coated, there is a feature that can improve the adsorption power of bacteria or organic materials without decomposing organic polyurethane foam and organic paint.

However, when such a paint is used on a sheet of a patient such as a sick elderly person or a sick person, for example, light does not come into contact with the part where the patient's body is placed in the sheet. Although odor or antibacterial effects are most necessary, there is a problem in that odor or antibacterial effects are not obtained. In addition, even when the conventional paint is used for a portion or member to which light does not come into contact, there is a problem that effects such as an odor agent or antibacterial due to a photocatalytic action are not obtained. Moreover, there is a problem that the conventional paint easily peels off even when it arrives.

The present invention has been made in order to solve the problems of the conventional coating composition, the object of the present invention is to provide a coating composition mixed with a dark catalyst that exhibits an effect such as odor or antibacterial even when used in a part or member that does not contact light. to be.

       Still another object of the present invention is to provide a coating composition in which a dark catalyst is mixed, which does not come off even when the paint arrives.

The road composition in which the dark catalyst of the present invention is mixed to achieve the above object is constituted by mixing a non-elutable inorganic, organic dispersant and hydroxysin apatite.

In addition, the present invention is characterized by mixing one ceramic selected from the group consisting of a far-infrared radiation ceramic, an ionic ceramic, and an odor removing ceramic with a non-elutable inorganic, organic dispersant, and hydroxyapatite mixture.

In addition, the paint produced by mixing non-elutable inorganic, organic dispersant and hydroxysin apatite has an odor removal, sterilization and antimicrobial effect similar to photocatalytic reaction in response to heat (temperature) and water (humidity). This action is considered to be because an optical semiconductor and an organic dispersing agent are used instead of the inorganic binder in the conventional coating material. That is, the paint produced according to the present invention not only removes odors and sterilizes when the light is in contact, but also reacts to heat or moisture even when light is not in contact. Do it.

And since the organic dispersing agent is non-elutable, the coating material thus obtained becomes difficult to peel off.

Far-infrared radiation ceramics have a relaxation effect on humans by emitting far-infrared rays with a wavelength of 9 to 10 µm, which is the absorption wavelength of human beings, and at the same time, by emitting far-infrared rays with a wavelength of 4-14 µm as the absorption wavelength of plants and animals. To foster (育成) action.

Ionic ceramics act on air purification and act on calcium or sodium in human blood to promote weak alkalinization of blood. In particular, ionic ceramics increase anions in the blood. Increased negative ions in the blood, the active metabolism is believed to help improve the body's resistance and autonomic nerves. In other words, ionic ceramics act to regulate autonomic nerves, normalize the intestinal environment, improve blood purification and immune function, and control the loss of vitamins. As such an ion ceramic, the ceramic which radiates an anion is preferable.

Odor removal ceramics prevent chemical adverse effects on the human body by chemisorption, physical adsorption or ion adsorption, or decomposition of chemicals, and prevents the occurrence of odors or irritating odors.
