Description

Ocher plaster paints containing photocatalyst solution and activated carbon {a}

The present invention relates to a plaster paint using a photocatalyst (Tio ₂ ) solution, activated carbon (powder, granular) and seaweed solution, and loess, stone powder (mica), and more specifically, ultraviolet light using a photocatalyst (Tio ₂ ) solution. When irradiated, photoelectrons are emitted, activated carbon (powder, granule) is used to absorb harmful elements, seaweed is used for adhesion, and ocher and stone powder (mica), which is beneficial to the human body, can be used instead of wallpaper. It relates to a loess plaster paint containing a photocatalyst solution and activated carbon.

Generally, in the past, buildings such as houses were constructed using natural materials such as wood, stone, and ocher, but as building materials such as cement are developed, the frequency of using natural materials such as ocher gradually decreases. have.

In the construction process, the plastering process, which is performed at the finishing stage of wall or floor, is mainly performed with cement. Cement has high strength but releases harmful components to human body, and blocks various waves that have a good effect on human body. Destroying the biological rhythm will harm your health.

Recently, the ocher plastering method has been developed by mixing ocher and water to compress and plaster the mixture on the floor or wall of a building. The conventional ocher plastering method uses a moldine and a chemical adhesive to perform plastering. There is a problem in that it is harmful to the human body by progressing, and a limit occurs in the adhesion force.

Conventional ocher finishing material has a patent No. 10-0300446 (registered on June 16, 2001), which is made by putting ocher powder and hemp bark into elm juice made by mixing ocher powder and elm bark with water The flour paste was applied, dried and coated again, and then the flour paste was dried, thus making the process complicated and very difficult to obtain materials.

In addition, Korean Patent Publication No. 10-2001-79159 (published Aug. 22, 2001) mixes waste paper fibers and 칡 fibers in natural clay in a constant ratio to prevent cracking of the loess and increase its strength. When exposed, it is easily soluble and has a weakness that is easily broken due to its hardness, and when used as a finishing material, there is a defect that loess soil gets on clothes or body.

Activated carbon is powder and granular, and these are widely used in various fields as well as in water treatment and air treatment. Coal and Coconut based granular activated carbon raw materials are used depending on imports. Doing.

In addition, the photocatalyst (Tio ₂ ) solution is called titanium dioxide, and when UV light is irradiated, photoelectron is emitted.

The band gap energy of the photocatalyst (Tio ₂ ) solution is 3.2 eV (λ390 nm). When the photocatalyst (Tio ₂ ) is irradiated with a wavelength of 390 nm or less emitted by a general ultraviolet lamp, photons and holes are excited and the sun is excited. It is known that a certain amount of photoelectrons are generated as light.

The photoelectrons and holes in the excited state are used in various fields such as antibacterial, antifouling and deodorizing by showing functions such as antibacterial, organic substance decomposition and deodorizing effect by the ambient atmosphere and continuous redox reaction.

Japanese Patent JP-006172 discloses a method of forming a coating layer by mixing titanium dioxide particles with NiCr metal particles and melting and scattering them with a high temperature flame using a thermal sprayer, but this method requires a high temperature of about 1000 ° C. or more. do.

The loess and stone powder (mica stones) of the present invention are distributed evenly throughout our country, so there is no problem in supply, and it is known that it emits wavelengths such as magnetic waves to keep the body's biological rhythm normally. Also gives a beneficial effect.

Plastering and painting on buildings using loess and stone powder (mica) prevents the toxicity and electromagnetic waves of cement harmful to the human body, and has beneficial effects on the human body due to far infrared rays emitted from loess and stone powder (mica). give.

In particular, far-infrared rays expand the capillaries in the peripheral area to promote blood circulation and increase sweating, thereby discharging waste products and fats in the body to prevent aging of the skin and anionizing cations, which cause various unpleasant odors. Of course, it has antibacterial and antifungal effect with excellent adsorption power as well as clean effect.

In addition, if the sensation temperature is high even at low temperature due to heat transfer by radiant heating, and the far-infrared ray is absorbed by the human body, resonance effect and self-heating phenomenon can be expected, and energy saving effect of about 30% can be expected.
