Description

Paint using loess

The present invention relates to a paint, and more particularly, to a paint using ocher made of ocher, which is an environmentally friendly material, which does not harm the human body.

As is well known, people living in cement and concrete buildings pose health problems such as direct or indirect weakness of the body due to cement toxicity.

In addition, even in the case of the paint is generally used as a material that does not have a special affinity with the human body as a form of matching the color only in the humid summer, it did not respond properly to the growth of mold, microorganisms or various bacteria.

In addition, the paint as described above is known as a residential environment that is easy to harm the health of the indoor air is cloudy because various harmful gases are emitted from the applied paint when the coating is applied to the wall.

The present invention has been made in order to solve all the problems according to the prior art as described above, and is made with the main component of loess, an environmentally friendly material, to provide a paint using loess that does not harm the human body and the surrounding environment. There is this.

The paint using the ocher according to the present invention, the fine clay powder 30 to 40% by weight, the acrylic emulsion resin 20 to 30% by weight, water 15 to 25% by weight, calcium carbonate (CaCO ₃ ) 5 to 15% by weight, titanium dioxide (TiO ₂ ) It has technical features in that it comprises 0.1 to 5% by weight.

According to the paint using the loess of the present invention, while satisfying all the basic requirements required by the paint, it has an excellent deodorization rate, has an environment in which the growth of fungi is suppressed, and produces a beneficial effect on the human body by releasing a large amount of far infrared rays. In addition, there is also an effect that the various bacteria harmful to the body is significantly reduced where the paint using the loess of the present invention is applied.

The paint using the loess according to the present invention, the fine clay powder 30-40%, the acrylic emulsion resin 20-30% by weight, water 15-25% by weight, calcium carbonate (CaCO ₃ ) 5-15% by weight, titanium dioxide (TiO ₂ ) It comprises 0.1 to 5% by weight.

The above-mentioned loess is mainly distributed in Northeast Asia, including the Korean Peninsula and the Yellow River coast of China's North China Region. 6 ~ 6%, 10 ~ 13% of alumina (Al2O3), 2% of magnesium (Mg) and sodium (Na), and 1.5% of Kali, 8% of lime, and 8% of lime. It has been known to have beneficial weakness to.

Therefore, it has been used importantly as a material for houses since ancient times, and was used as a tool of living by making dishes and utensils. In addition, ocher has an excellent effect in treating detoxification and disease, so it is used as an important medicine in oriental medicine.

The main oriental texts, such as Chocho River, Tongyi Bogam, and Hyangjeokbangbang, are the most widely used soils with ocher's color. It has been documented that it has excellent efficacy in children and children's diseases. In addition, the heavy water part of the herbaceous wood is called Jijang or Sojang, which is poured from the ocher to pour water, and it is recorded that it is effective in detoxifying various poisons and stabilizing the mind.

In recent years, many studies have been conducted on scientific research on ocher, and the ocher emits a large amount of far-infrared rays and blocks harmful electromagnetic waves. It has also been scientifically proven to have a very beneficial effect on the human body.

When painting paint using ocher according to the present invention configured as described above on the surface, the oil, dust, and other impurities of the surface are completely removed, and in the case of repair painting, the old structure film is removed and then coated. .

After diluting about 5% during painting, paint is uniformly applied using a brush or roller. When the absorption is severe, hi-sol is applied first, and when the unevenness is severe, it is filled with a filling material and then painted.

Figure 1 of the accompanying drawings is a cross-sectional view of a fine grinding device for finely crushing the loess which is the main component of the paint using the loess according to the present invention, Figure 2 is an air supply system and powder collection system in the fine grinding device shown in FIG. It is a schematic diagram which shows this connected state schematically.

As shown, the fine grinding device for finely pulverizing the loess which is the main component of the paint according to the present invention, the powder chamber is injected into the compressed air chamber 10 is filled with a high-pressure air, the grinding chamber 20 is pulverized It is formed, the discharge of the powder raw material pulverized in the grinding chamber 20 is controlled by the pitch (30).

The compressed air chamber 10 is a cylindrical space having a closed upper and lower surfaces, and is connected to the air tank 50 through a compressed air supply hose 40 connected to the outer wall 11.

At this time, the air filter 60 for filtering the foreign matter in the air is mounted on the outlet side of the air tank 50, the air tank 50 is connected to the air compressor (70).

The pulverization chamber 20 described above is formed in the center of the compressed air chamber 10 and is partitioned from the compressed air chamber 10 through the cylindrical partition wall 21. At this time, the upper and lower ends of the partition wall 21 are welded to the upper and lower surfaces of the compressed air chamber 10, respectively.

The partition wall 21 is provided with a plurality of fine injection holes 21a for injecting compressed air in the compressed air chamber 10 into the grinding chamber 20 at regular intervals.

Holes are formed in the centers of the upper and lower surfaces of the grinding chamber 20, respectively, and the holes formed on the upper surface are connected to a discharge tube 80 for discharging the pulverized powder raw material to the outside, and the holes formed on the lower surface will be described later. Pitch 30 is screwed.

On the other hand, the grinding chamber 20 is connected to the raw material supply pipe 90 for supplying the powder raw material. At this time, the raw material supply pipe 90 may be connected to the grinding chamber 20 through the compressed air chamber 10 as shown in the drawing or may be directly connected to the upper surface of the grinding chamber 20.

The above-described pitch 30 controls the discharge of the pulverized powder raw material by opening or closing the end of the discharge pipe 80, and also allows the powder raw material scattered by the compressed air to collide finely.

The pitch 30 penetrates while screwing a hole formed in the bottom surface of the grinding chamber 20, and when the upper end thereof rises to close the end of the discharge tube 80, the discharge of the pulverized powder raw material is stopped and vice versa. When the end of the discharge tube 80 is opened, the pulverized powder raw material is discharged.

On the other hand, a plurality of knobs 31 for holding the pitch 30 to turn the pitch 30 by holding the hand 30 is mounted at regular intervals.

Hereinafter, the operation of the fine grinding device configured as described above will be described in detail.

First, the compressed air generated by the air compressor 70 is stored in the air tank 50 and then foreign matter is removed while passing through the air filter 60 and supplied to the compressed air chamber 10 through the compressed air supply hose 40. do. The powder raw material is supplied into the grinding chamber 20 through the raw material supply pipe 90.

The compressed air filled in the compressed air supply hose 40 is injected into the grinding chamber 20 through the plurality of fine injection holes 21a formed in the partition wall 21. At this time, due to the strong injection pressure of the compressed air, the powder raw material in the grinding chamber 20 is finely pulverized while colliding with the powders or colliding with the pitch 30 passing through the grinding chamber 20 while being actively scattered.

On the other hand, when holding the handle 31 and the pitch 30 is turned up to raise the upper end of the pitch 30 to block the discharge pipe 80, if the pitch 30 is reversed to turn down the upper end of the pitch 30 is discharge pipe Separated from 80, the discharge tube 80 is opened.

Therefore, after the grinding is in progress or completed in the grinding chamber 20, the discharge pipe 80 is blocked or opened by using the pitch 30, thereby controlling the discharge of the fine powder.

The fine powder discharged through the discharge tube 80 is finally collected in the collector 100.
