Description

Boiled yellow soil solution, and natural coatings and natural additive for mortar using the same}

The present invention relates to a hydrophobic ocher solution and a natural ocher coating solution and a natural ocher mixed agent for mortar using the same, and more specifically, there is no problem such as dust generation or burying while being manufactured using only ocher and natural materials beneficial to the human body. The present invention relates to a hydrophobic ocher solution used as a material for preparing pure natural ocher coating solution and ocher mortar, and an ocher coating solution and ocher mixture for mortar prepared using the same.

It is known that ocher emits far-infrared rays which is beneficial to the human body, and in recent years, attempts have been actively made to develop building materials using ocher, with an increasing interest in health.

However, ocher has a high shrinkage expansion rate, and when used as a building material without processing, the cracks are large due to the dry shrinkage phenomenon, and the adhesiveness is not high, so that the fragments or dusts are high, and they are buried on clothes.

Therefore, in order to solve this problem, most of the building materials using ocher supplement the disadvantages by adding cement or artificial adhesive.

For example, natural paints or coating liquids using ocher are used to make a suitable viscosity by mixing natural glue or synthetic adhesive components such as starch grass with mainly ocher powder.

However, when natural grass is mixed in order to maximize the benefits of natural loess, it may cause problems such as mold blooming at high temperature and high humidity, such as during the rainy season. Even if dust is generated or not, the yellow dust on the clothes or hands is often not applied when contacted.

On the other hand, in order to solve such a problem, when the synthetic adhesive component is mixed, it is contrary to the original intention to achieve a beneficial effect on health by using ocher which is a natural material beneficial to the human body, but rather adversely affect the health by the synthetic adhesive component. There is even concern, which is undesirable.

As one of the fields of building materials using ocher, there is a desire to manufacture natural ocher mortar instead of cement mortar using ocher and to use it for the construction of ocher walls or ocher. However, ocher mortars known to date are mostly added with artificial additives such as cement components to supplement strength, which is not a pure natural material, and thus can not properly exhibit the health benefits of ocher. There is.

In addition, when only natural ingredients such as natural grass are mixed in order to take full advantage of the natural loess, the mold may cause problems such as mold growth at high temperature and high humidity, such as in the rainy season. Falling, cracking or dusting of the loess may cause dust, and when contacted with ocher dust on the clothes or hands are often not widely used.

The present invention has been made to solve the above-mentioned problems of the prior art, and does not cause hygiene problems such as mold or dust generation while using only ocher and pure natural materials beneficial to the human body, and thus can be widely used as an eco-friendly building material. In addition, it provides a natural ocher coating liquid and a hydrophobic ocher liquid used in the production of natural ocher mixtures for the mortar, and a natural ocher coating liquid and mortar prepared using the same, which can be manufactured at low cost because of a simple manufacturing process and low material cost. An object of the present invention is to provide a natural ocher mixture.

The constitution of the hydrophobic ocher solution according to the present invention for solving the above problems,

The ocher is mixed with water to obtain ocher, the impurities are removed from the ocher to obtain purified ocher, and then the purified ocher is heated to 60 ° C. or more.

In addition, the natural ocher coating liquid according to the present invention,

The hydrogenated ocher solution according to the present invention is mixed with starch powder and glutinous rice powder selected from wheat flour, corn flour, potato powder and rice flour and heated to 60 ° C. or more, thereby uniformly modifying the plastically modified ocher particles and the natural adhesive component. Characterized in that the mixture is made.

On the other hand, natural loess mixture for mortar according to the present invention,

The hydrogenated ocher solution according to the present invention is mixed with starch powder selected from flour, corn flour, potato powder or rice flour, glutinous rice flour, and mulberry porridge which is a hanji material, and the mixture is heated to 60 ° C. or higher, thereby plastic deformation. It is characterized in that the natural adhesive component and the natural filler component is uniformly mixed with the ocher particles.

Preferably, to the above hydrophobic ocher solution, a flavonoid extract obtained by extracting from ginkgo biloba is further added to obtain an ocher coating solution or a natural ocher mixture containing natural antimicrobial agents uniformly.

The hydrophobic ocher solution according to the present invention is manufactured by using the natural ocher coating solution, and applied to the walls or floors of the room instead of paint or wallpaper, so that the decorative effect and the far infrared ray emission effect beneficial to the human body can be obtained at the same time. It can be used as a building material.

In addition, when the natural ocher mixture for mortar is prepared using the hydrophobic ocher solution according to the present invention, the ocher mortar is used to prepare the ocher mortar and used as an interior finishing material of a building, not only exhibits proper durability, that is, strength during use. Ocher powder is not buried or dust is generated, it can be used as an eco-friendly building material that can be installed on the walls or floors of the room to obtain a decorative effect and a far infrared ray emission effect beneficial to the human body at the same time.

In particular, the natural coating solution using the ocher according to the present invention and the natural ocher mixture for mortar is not only harmless to the human body using only natural ingredients as a raw material, it is also hygienic because it can suppress the growth of mold and bacteria, and the ocher powder in water Since the particles are plasticized and uniformly distributed in a uniformly dispersed state, there is an advantage in that dust is not generated during use or contaminated upon contact.

In addition, the hydrogenated ocher solution according to the present invention and the natural ocher coating solution and ocher mortar prepared using the same are inexpensive because they are made by simple operations such as mixing, sedimentation, and heating. The advantage is that it can be manufactured at a cost.

Hereinafter, the configuration of the present invention in more detail.

The hydrogenated ocher solution according to the present invention is obtained by mixing ocher with water to obtain ocher, removing impurities from the ocher to obtain purified ocher, and then heating the purified ocher to 60 ° C. or higher. The natural ocher coating liquid and the natural ocher mixture for mortar according to the present invention are to mix the natural material with the hydrogenated ocher solution to exhibit the necessary functionality as a building material.

In more detail about the hydrogenated ocher solution, the raw material ocher is mainly composed of particles of silt size (0.05 ~ 0.005㎜), the size of the ocher particles is mainly 0.02 ~ 0.05㎜ and loosely crushed by calcium carbonate Since the porosity is about 50-55%, the weight ratio is about 50%. Ocher, which is commonly found in Korea, is a mixture of silica and crystallization, and also contains some limestone. It is known that the chemical composition of loess is composed of 40 to 50% silica, 20 to 30% alumina, 8% lime, 5 to 6% iron, 2% magnesium oxide, 2% sodium and 1.5% potassium. The loess emits far-infrared rays, which are beneficial to the human body. The far-infrared rays are known to help the health of the human body by circulating blood and promoting the discharge of waste products.

It is recommended to use very fine ocher powder in order to prevent the generation of dust and to obtain a uniform coating after manufacturing the natural ocher coating solution using such ocher and constructing it in a building, but the cost of the micronized ocher powder is expensive. high. Therefore, the ocher used in the present invention does not necessarily need to be finely divided ocher powder.

Instead, in the present invention, the ocher and water are mixed well at a ratio of about 1: 1.5 to 5 to obtain ocher, and the ocher is removed using floating cloth to remove floating impurities, and left to stand for about 2 to 3 hours for sand or Solid impurities such as stones are precipitated and the impurities are removed by separating them from the supernatant to obtain purified loess, which is used as raw material for loess.

In this process, the particles of ocher are broken down and suspended impurities, as well as impurities such as gravel and sand, are removed. The mixing ratio of ocher and water may be determined in consideration of the convenience of operation within the range in which the final product can obtain an appropriate viscosity, but the above range may provide a natural ocher coating liquid or a natural ocher mixture for mortar, which is not too high or low in viscosity. It is preferable.

Thus obtained purified ocher is heated and boiled at a temperature of 60 ° C. or more for 10 minutes or more, and the ocher particles in the ocher are plastically deformed with pure ocher granules to obtain a plastically deformed ocher solution. Boiling about 10 to 20 minutes at an as high temperature as possible, preferably 80 ° C. or higher, more preferably 100 ° C., saves time and provides a sufficient hydrophobic effect.

On the other hand, when explaining the process for producing a natural ocher coating solution using the hydrophobic ocher solution according to the present invention, starch powder and glutinous rice powder selected from flour, corn flour, potato flour and rice flour is mixed with the hydrophobic ocher solution And heating at a temperature of 60 ° C. or higher, preferably 80 to 100 ° C. for about 15 to 20 minutes.

Here, other starch powder, such as glutinous rice flour or flour, is added to complement the adhesion of the coating liquid. Ocher is viscous and can be entangled with each other to provide a certain level of coating effect even if no adhesive is added. However, since the affinity between each other is weak and dust and cracks may occur during use, the glutinous rice flour and flour are mixed to compensate for this. Boil to make up the adhesive component.

Glutinous rice flour of the starch components can obtain high adhesion even with a small amount of use, but because the price is expensive, mixed with glutinous rice flour and other starch powders such as flour, corn flour, potato flour, rice flour in a ratio of 1: 1 do.

And it is preferable to add a natural antibacterial component in addition to the hydrolyzed loess and starch components. As such a natural antimicrobial component, ginkgo biloba leaves in water about 10 times the weight of ginkgo biloba leaves and heated to a temperature of 100 ° C. or more for 1 hour or more, preferably 60 to 90 minutes, to extract the flavonoid component which is an antimicrobial component contained in ginkgo biloba leaves. Flavonoid Extracts are used.

This flavonoid extract has antimicrobial properties and has the effect of preventing mold and preventing pest access. In addition, since it consists of pure natural ingredients, the ocher coating liquid according to the invention made by adding it is made of pure natural materials.

The use ratio of other starch powders such as flavonoid extract and glutinous rice flour and flour is generally 1 kg of other starch powder such as glutinous rice flour and flour for 10 l of flavonoid extract. If flavonoid extract is not used, use glutinous rice powder in the same amount of water instead of flavonoid extract.

In the final step, the mixture of the natural adhesive component and flavonoid extract, such as the mixture of the hydrolyzed ocher solution, and heated together to boil for 15 to 20 minutes, finally the natural ocher coating solution using the loess according to the present invention You get In this case, the mixing ratio of the flavonoid extract to the hydrolyzed plastic loess is usually about 30 to 70 parts by weight of the flavonoid extract based on 100 parts by weight of the loess. However, the above mixing ratio may be adjusted so as to have a suitable viscosity and adhesive force, and is not particularly limited.

In this case, a small amount of a natural colorant may be added to change the color of the loess, and a functional enhancement effect such as aroma effect may be obtained by adding a natural essential oil extracted from the herb.

In addition, if the process for producing a natural mortar mixture for mortar using the hydrophobic loess according to the present invention, the hydrophobic loess according to the present invention is selected from flour, corn flour, potato flour or rice flour By mixing starch powder, glutinous rice flour and Korean paper mulberry, and heating the mixture to 60 ° C or higher, preferably 80-100 ° C, the natural adhesive component and natural filler are uniformly mixed with the plastically deformed ocher particles. .

The other part of the natural loess mixture for mortar is not different from the production of the natural loess coating solution. However, in the manufacture of the natural loess mixture for mortar, the mulberry porridge which is a material of Hanji is further mixed as a natural filler.

The mulberry porridge is used as a raw material of Korean paper, and the skin of the skin of the mulberry is soaked in water and cut into 40 ~ 50cm length, boiled in lye, steamed and dried in the sun, and then pulverized to make it like bamboo shoots. It is manufactured by mixing the juice extract from the root of the, the fiber is tough and long, can effectively supplement the stiffness of the ocher mortar.

It is also mixed with hydrolyzed ocher solution by mixing it with flavonoid extract as well as glutinous rice flour or starch powder, which are natural adhesive ingredients. That is, when the mixture of the flavonoid extract and the mulberry porridge is made, it is mixed again with the mixture of the hydrophobic ocher and the flavonoid extract and the natural adhesive component, heated together and boiled for 15 to 20 minutes, for mortar You get a natural loess mixture.

Here, the mulberry porridge is mixed at a ratio of 0.7-1 kg to 10 l of the flavonoid extract, and the mixing ratio of the flavonoid extract and the mulberry porridge mixture to the hydrolyzed loess is usually about 100 parts by weight of the hydrolyzed ocher solution. The mixture is used at about 30 to 70 parts by weight. However, the above mixing ratio may be adjusted to have appropriate viscosity and viscosity, and is not particularly limited.

The natural ocher mixture obtained in this way can be put into a mixture of ocher powder, ocher powder and sand, and kneaded well to produce natural mortar using pasty ocher, and can be used as a building material. Typically, mortar is prepared by mixing the loess powder with sand and the natural loess mixture in a ratio of 1: 3: 1.5 to 2.

In this case, a small amount of a natural colorant may be added to change the color of the loess, or natural aroma essential oils extracted from herbs may be added to impart other functionalities such as aroma.
