Process diagram according to the present invention

The present invention is a natural mineral with a white clay relates to a method of manufacturing a functional internal finishes in a more particularly 40 to 70% by weight of clay mainly composed of silver and titanium dioxide can be 20-30% and a functional material (TiO _2), tourmaline ( Tourmaline) 3 to 6% by weight and the like. As the additive, a dispersant, an antifoaming agent, a sedimentation inhibitor and the like were used. Here, as a binder, it is related with manufacture of the coating which uses 10-30 weight% of potassium silicates or lithium silicates, and 5-10 weight% of water-soluble acrylics.

Water and oil paint are used to paint the interior or exterior of buildings. Oil paint is developed in the form of charcoal, ocher paint, etc. A method of preparing a paint or super medium by mixing a charcoal and ocher powder with PVC has been applied.

The paint prepared as described above has a unique index black and ocher color of the raw material powder, so it is difficult to realize various colors.

And the development of the paint on the clay which is known to be similar or superior to the loess is still insufficient.

The present invention has been made to solve the above problems,

White clay is a natural mineral that has 20 times better efficacy than loess, which is good for our bodies. Like clay, white clay generates far-infrared rays, activating cells' physiology and generating heat energy to release harmful substances, thus eliminating human poison and maintaining healthy life. In addition, the white clay used in the present invention as a mineral having high utilization as cosmetics and food additives for a long time to promote metabolism and prevent aging is a raw natural mineral that is carefully selected and obtained in Gangwon-do and Chungcheong-do. If natural materials obtained in this way are used instead of paint on walls, ceilings, floors, furniture, etc., it is possible to manufacture paints that protect our bodies from harmful substances from cement or various building materials. The purpose of the present invention is to prepare a paint having high water resistance and heat resistance by using a water-soluble acrylic emulsion and an inorganic material potassium or lithium silicate as a binder.

 In addition, the use of natural inorganic pigments to provide an effect that can provide a variety of architectural interior finishing materials.

To achieve the above object, the preferred embodiments of the present invention have the following effects on the composition and the examples and the composition.

First, look at the preferred configuration and embodiment of the present invention.

Example 1

A first stirring step of preparing an adhesive by putting 20 to 40% by weight of silver nano water, 10 to 30% by weight of potassium silicate or lithium silicate, and 5 to 10% by weight of a water-soluble acrylic emulsion into a reaction vessel and stirring for 30 minutes at a constant stirring speed;

Example 2

A second stirring step of adding 1 to 2% by weight of the dispersant and 2 to 3% by weight of the antifoaming agent to 1 to 2% by weight of the antisettling agent and stirring for 30 minutes at a constant stirring speed in Example 1;

Example 3

In the above Example 2, 40 to 60% by weight of clay, 3 to 6% by weight of tourmaline, and 3 to 6% by weight of titanium dioxide were stirred for 60 minutes at a constant stirring speed to prepare a paint using clay and silver ionized water. It is a process.

In the above Example 3, it is preferable to use 40 to 60% by weight of clay. (320 mesh or more) When the amount of use is less than 40% by weight, the effect generated from the clay, which is the object of the present invention, is weak, and 60% by weight is used. When exceeded, since the binder is relatively contained, adhesion with the surfaces of various structures is not easy. In the above embodiments, when the inorganic adhesive potassium silicate or lithium silicate is used alone, the adhesive strength decreases, and as the amount of the inorganic silicate is increased, the water-soluble acrylic emulsion is added to reinforce the adhesive strength, and the amount of the inorganic adhesive is preferably used in an amount of 10% by weight or less. Do. The reason for using a water-soluble acrylic emulsion is that potassium silicate and lithium silicate itself are strongly alkaline, so when a PVA-based binder is generally used, a precipitate is generated and thus a product cannot be formed.

The composition ratio (%) of the clay used in the present invention is shown in [Table 1].

Looking at the effects of the main composition of the coating using the functional finish using the clay of the present invention produced by the composition and process as described above are as follows.

In general, the efficacy of known clay is as follows.

It produces a large amount of negative ions and clears the air.

Negative ions keep the room clean and fresh by curing, sedimenting and removing cations contained in various harmful substances around us. Thus, the nose and throat of those who were not bronchial are refreshed. The white soil absorbs all the smells of cigarettes, foods, and scents, so you don't need a fragrance.

Oxygen generation keeps the head clear and cool.

Lack of ventilation can lead to heavy head and headaches. White clay makes ozone harmful to human body by making anion oxygen (O ₂ ) which is beneficial to human body.

Lighten your body with far-infrared radiation.

White clay itself activates cellular functions by radiating far-infrared rays to help expand microvascular artery veins, promote systemic circulation, relieve stress, and sleep better. If the body's circulation is not working properly, toxins accumulate and become a disease. Toxin purification occurs during sleep, and after sleeping, the body becomes lighter.

The house is clean because no static electricity is generated.

Since the negative ions do not generate static electricity, fine dust floating around the house does not stick to curtains, furniture, clothes, etc., making it easy to clean and clean the house. In addition, the sound of the sound, the intensity of light, etc. makes the state comfortable to accept.

It is also mentioned in various literatures. In Dongbogam, it is said that the nature is warm, the taste is bitter, and it is sweet, and there is no poison and it is recorded as a good medicine for wounds. It is said that the rice cakes were made by mixing five pieces of soil with one piece of rice flour. Jibong Yul says that the volcanic eruption occurred three years after the volcanic eruption in the fourth year of Silla Taejong. At that time, the rock was broken from the mountain collapsed by eruption and became rice. It was like real rice.

The bactericidal and antimicrobial effects of silver have long been known. However, the cost increase was inevitable when applied to each product, which did not follow economic feasibility. However, the application of silver nanotechnology has made it possible to economically produce products applying these silver effects. Silver Nanotechnology means that silver is made into nano-sized powder and coated on the product, or silver powder is mixed with a material to make a product, or silver is ionized to make a silver solution and mixed with the material to make a product, or used directly for sterilization. Says technology. In addition, since silver itself is not oxidized in air and water, the antimicrobial and sterilization life of silver coated or silver solution products is semi-permanent, which makes silver nanotechnology more useful. The technology of silver nano water production has been developed for a long time, and has been applied since 1997 under the name of colloidal silver in Korea.

A solution is a solution in which a substance is dispersed evenly in a liquid in a molecular or ionic state. On the other hand, a particle having a diameter of 1 nm to 100 nm larger than a normal molecule or ion is dispersed without agglomeration or precipitation in a gas or a liquid. The state is called a colloidal state, and the entire colloidal state is called a colloid. Colloidal silver is the ionization of silver by electrolysis and refers to the uniform distribution of silver ions (Ag ⁺ ) in a liquid. The colloidal silver particles are stably present in the solution without agglomeration with each other because colloidal particles bear the same kind of electricity and are repulsed with each other.

The biggest advantage of potassium silicate and lithium silicate is that it can produce higher molar ratios of products than sodium silicate and potassium silicate. Lithium silicate is a water glass series such as sodium silicate potassium silicate, but has a higher water resistance and heat resistance than the two products and is widely used as a ceramic binder. Potassium silicate or lithium silicate can be used in the composition of high performance rust preventive paints used in marine coatings or industrial applications. It is used to increase the strength or heat resistance of emulsion coatings such as urethanes. In addition, it is used in various applications such as anti-neutralization agent, surface strengthening agent, etc. due to the property of penetrating and reacting the surface of cement and concrete to form a strong bond.

Modern people live in indoor spaces that are exposed to invisible electromagnetic waves, polluted air and chemicals.In particular, new buildings use radioactive materials such as radon, unpleasant odors, and formaldehyde and VOC, which are harmful substances emitted from building materials. Due to headache, vomiting, atopy, and allergic symptoms, sick house syndrome (Sick House) is experiencing difficulties. KBS 1TV's environmental special reported the following concrete hazard test results. The three major life stresses include chemical stress, electromagnetic stress, and concrete stress. Among them, a Japanese scientist claims that people living in concrete houses have a lifespan of 9 years shorter than those of wooden houses. According to the results of experiments on rat survival environment for concrete, aluminum and wood in the same environment, Of the later 100, 93 concrete, 48 aluminum, and 15 wood died. Japan, which used concrete as a representative building material from the 30's, has changed its perception since the 80's, and the Ministry of Education promotes the use of wood in concrete for the main material of new schools. And in the 70s, the architect Tadao Ando was regarded as the biggest tragedy and mistake of the building industry by using the entire building as exposed concrete, which caused a great repercussion of the building industry.

In addition, since May 29, 2004, the Ministry of Environment has been enacting and operating indoor air quality related laws that regulate indoor air quality in multi-use facilities, and the Act defines indoor air quality and measurement methods. It is required to measure and disclose the air quality before moving in, and the recommended standards for harmful substances (formaldehyde, organic compounds) will be set in the future. The Ministry of Land, Infrastructure and Transport is conducting research services to specialized institutions to prepare housing design standards (ventilation facilities, etc.) and specification standards for maintaining the recommendations of the Ministry of Environment, and plans to supplement housing legislation in conjunction with housing performance evaluation system.

The present invention is to solve the above problems, when used as a finishing material of the inner wall of the building using the paint prepared by the present invention due to the adsorption effect of the inherent clay soils adsorbed and deodorized in the interior space and added Other materials can provide functionalities such as anion and antibacterial to reduce bacteria and fungi, thereby creating a pleasant indoor environment. In addition, the use of natural inorganic pigments also has the effect of providing a variety of interior finish for building colors.

At home and abroad, there is an increasing demand for environmental quality and quality of life in daily life, so the demand for finishing materials using eco-friendly materials is expected to increase. In addition, as consumer interest and environmental diseases increase, domestic safety standards, especially for building materials such as interior and exterior materials and interior materials, are expected to become more stringent, and related industries are expected to increase. .
