The present invention relates to a building finishing material using the soil and its construction method, and more specifically, to the construction of the building finishing material used for the finishing of the floor and ceiling, including the interior and exterior walls of the building using the soil, the low thermal conductivity of the soil Insulation effect can be expected by the components, and it adsorbs various harmful components and is made of eco-friendly materials and does not emit harmful substances such as formaldehyde, and has excellent hygroscopicity and sound insulation to reduce ambient noise, and The present invention relates to a building finishing material using a clay that can provide a clean space with excellent adsorption and deodorizing power and has humidity control ability to control indoor humidity.

Modern buildings are constructed by finishing mortar plastering on building walls and floor ceilings, and using styropol or gypsum board plywood for finishing insulation and wall coverings.

In the conventional construction form as described above, cement is used as the main material, and cement mortar method, which is the main material of cement, is made of limestone into pulverized fine particles and added with chemicals and adhesives. It is to be solidified.

As such, the cement-based building has a high thermal conductivity, which directly transmits indoor and outdoor temperatures, resulting in deterioration in summer and heating efficiency in winter.

In addition, additional materials are required for finishing the interior of the building by using separate chemical adhesives, such as burying floorboards or wallpaper, or painting with paint, as well as harmful substances such as environmental hormones due to the use of chemicals. There is a problem that is released.

Therefore, as an alternative to solve the above problems is to provide a building finishing material using natural materials, thereby requiring environmentally friendly building interior and exterior materials, the government is actively recommending this.

Among the materials that can give a natural texture, wood is difficult to purchase high-quality materials due to the exhaustion of resources, and therefore, the artificial wooden atmosphere is produced by making synthetic resin products the limits of wood supply. On the other hand, the stone is relying on imports because it does not satisfy the demand by limiting the development to the limit of natural destruction.

In addition, some of the building construction materials and interior and exterior materials use ocher, but the ocher finishing materials used in the past provide many effects such as improving the blood circulation of the human body by radiating far infrared rays, but their use is mainly used only for indoor walls. There was a problem that the degree was insufficient, the surface is easily broken due to its rigidity, not only weak to impact, etc., but also has a practical difficulty in forming a finish by itself because the color is dark.

The present invention has low thermal conductivity and can be expected to have a thermal insulation effect, while adsorbing various harmful components and at the same time made of environmentally friendly materials do not emit harmful substances such as formaldehyde, excellent hygroscopicity and sound insulation to reduce ambient noise, odor or The purpose of the present invention is to provide a building finishing material and a construction method using the soil which can control the indoor humidity with humidity control ability while providing a clean space with excellent adsorption and deodorizing power of harmful components.

The present invention for achieving the above object is in the building finishing material used for the finishing of the floor and ceiling, including the inner and outer walls of the building, the building finishing material is 50-60wt% soil, silica sand (SiO2) 10-20wt%, Provides a building finishing material using the soil composed of 20-30wt% inorganic additives, 1-5wt% acrylic resin.

In addition, in the construction method of the building finishing material used for finishing the interior and exterior walls of the building, floors and ceilings, 50-60wt% of pure soil, 10-20wt% of silica sand (SiO2), 20-30wt% of inorganic additives, acrylic resin 1 A first step of preparing a building finishing material composed of -5 wt%, a second step of mixing 60-80 wt% of the building finishing material and 30-40 wt% of water, and applying the building finishing material mixed with water to the surface to be finished It provides a construction method of the building finishing material using the soil made of the third step, the fourth step of curing the applied building finishing material at room temperature for 2-3 days.

According to the building finishing material using the soil of the present invention, the thermal conductivity can be expected to have low thermal conductivity, adsorb various harmful components and at the same time, it is made of eco-friendly materials and does not emit harmful substances such as formaldehyde, and absorbs moisture and reduces the ambient noise. It is excellent in voice, excellent in adsorption and deodorizing power of odors and harmful components, and can provide a clean space, but also has a very useful effect of controlling indoor humidity with a humidity control ability.

Hereinafter, the configuration and operation of the building finishing material and its construction method using the soil of the present invention will be described in more detail.

First, the building finishing material using the present invention loam in the building finishing material used for finishing the floor and ceiling, including the inner and outer walls of the building,

The building finishing material is composed of 50-60wt% of pure soil, 10-20wt% of silica sand (SiO2), 20-30wt% of inorganic additives, and 1-5wt% of acrylic resin.

At this time, the soil is water 2-5wt%, silicon dioxide (SiO ₂ ) and insoluble material (insol) 30-50wt%, aluminum oxide (Al ₂ O ₃ ) 5-10wt%, iron oxide (Fe ₂ O ₃ ) 2 White acid consisting of -5wt%, calcium oxide (CaO) 20-30wt%, magnesium oxide (MgO) 1-3wt%, sodium oxide (Na ₂ O) 0.1-0.2wt%, potassium oxide (K2O) 0.5-1wt% 90 to 95 wt% of soil and 5 to 10 wt% of inorganic hardener are mixed.

The fine soil is composed of fine particles to make the surface smooth after construction of the finishing material and to fill the gap between the silica sand particles so that the structure is solid. If the amount of soil is more than 60wt%, it contains a relatively large amount of expensive soil and the production cost increases, and if it is less than 50wt%, the efficiency of various soils, especially the ability of adsorption of harmful substances, is poor due to poor quality. This is because there is a disadvantage.

In addition, the silica is a core element of the building finishing material together with the above-mentioned soil, and refers to quartz granulated sand containing silicon dioxide anhydrous silicon dioxide (SiO₂), coastal silica, mountain silica and artificial silica It is used as a raw material for glass products and bricks. Its effect is to improve the strength of building finishing materials so that the walls, ceilings and floors can be maintained firmly after construction of the finishing materials.If the silica sand exceeds 20wt%, the surface will not be smooth. If not, less than 10wt% is mixed, since the problem of the strength of the wall, the ceiling, the bottom surface is reduced, it is preferable to mix 10 to 20wt% of silica sand.

The inorganic additive is an element that determines the color and adhesion of each element, including ground and silica, 20-30wt% is mixed.

In this case, the inorganic additive may include an inorganic solidifying agent and an adhesive in order to make each element including the ground and silica sand evenly mixed and bonded, and to adhere firmly to the surface after construction. The pigment may be included so as to be set, and in addition, the water-soluble binder may be contained to adjust the viscosity to improve the coating power and to improve the smoothness of the construction surface.

When the content of the inorganic additive is less than 20wt%, the adhesive strength is insufficient, and easily peeled off. When the content of the inorganic additive exceeds 30wt%, the surface hardness is excessive after construction, so that the crack may be caused by the impact. 20-30wt% is preferably mixed to maintain the strength.

The acrylic resin is provided together with the inorganic additives to provide adhesion to each element, such as ground and silica, to be uniformly stirred and fixed in a cohesive state. In general, an acrylic resin refers to a polymer from an ester such as acrylic acid or methacrylic acid. The polymer of methyl methacrylate (methyl methacrylate) is typical, which is colorless and transparent, and light, especially ultraviolet rays, is better than ordinary glass, and it does not discolor even when exposed to the outdoors, has good chemical resistance, electrical insulation and water resistance. All have good characteristics.

The acrylic resin may be provided in a liquid or powder, the reason is that the content is limited to 1-5wt% The chemical component generated from the acrylic resin may threaten the health of the human body when contained in a large amount, less than 1wt% This is because there is a risk that the adhesion of each element is insufficient when mixed with.

The clay is composed of 90 ~ 95wt% of white acid and 5-10wt% of an inorganic hardener, and the white sand has a fine particle to make the surface smooth after finishing the construction and fill the gap between the silica sand to make the structure firm. It also works to improve the conservatism of building finishing materials.

White acid has the chemical composition of 2 to 5% moisture, 30 to 50% silicon dioxide (SiO ₂ ) and insoluble substances (insol), 5 to 10% of aluminum oxide (Al ₂ O ₃ ), and iron oxide (Fe ₂ O _3). ) 2 ~ 5%, calcium oxide (CaO) 20 ~ 30% by weight, magnesium oxide (MgO) 1 ~ 3%, sodium oxide (Na ₂ O) 0.1 ~ 0.2%, potassium oxide (K ₂ O) 0.5 ~ 1% By structure, it means the soil distributed in Baeksan area of Japan.

The white sand has a function to drastically increase the surface temperature, which can alleviate the deterioration in summer, and the strength and durability are higher than general concrete, and are environmentally friendly materials having excellent water permeability and water retention. In addition, natural soil as the main raw material can maintain the natural state, not only does not cause harmful substances, but also has the advantage of absorbing harmful substances, and goes well with the surrounding landscape of nature.

In addition, the inorganic solidifying agent is configured to improve the bonding strength and strength of the white acid soil, and may use inorganic natural hardening agents such as magnesium oxide, aluminum oxide, calcium oxide, and the like is not limited.

In addition, an inorganic system consisting of 30 to 70% by weight of silicic acid, 10 to 20% by weight of aluminum oxide, 10% by weight of magnesium oxide, 50 to 75% by weight of calcium oxide, and 1 to 10% by weight of other substances It is of course possible to use various kinds of known hardening agents such as hardening agents.

In addition, the loam is provided in a particle size range of 10-100nm, and generally silica is provided in a size of 1 ~ 2mm.

The reason for limiting the size of the loam to the size of 10-100 nm is to make the particle size of the loam fine and to coat the surface of the silica sand more smoothly, and to improve the surface area contacted with the loam to maximize the effect of the loam. .

Since the silica sand is mixed with the clay and constituted in the finishing material, it is preferable that the finishing material is provided with a small and fine size of 1 to 2 mm so that the surface of the finished material is evenly formed. According to taste, by adding ocher, green tea powder, natural pigment, etc. Can be provided in a variety of colors, to create a unique atmosphere according to the surrounding environment.

For reference, the building finishing material using the soil may be provided in the form of a powder, it may be provided in a liquid form mixed with water by changing the shape of the tile, it can be modified in various shapes and states.

The second step is a step of mixing 60-80wt% of the building finishing material and 30-40wt% of water, the water mixed with the building finishing material to make each element of the building finishing material more uniformly stirred and at the same time dilute the dilution of the building finishing material It is configured to make it easier to install construction finishing materials on the surface such as wall surface, etc., and its range does not flow down when the construction finishing materials are applied, and the application and coating properties are improved while the drying and curing process of construction finishing materials is quick and It is desirable to stir 30 to 40 wt% of water to ensure solidity.

The water should not contain substances that affect the quality of the soil, such as oils, acids, salts and organics. In general, drinking water is excellent as used water, but groundwater, industrial water, and river water can be used without any harmful effect on the quality of the ground.

The third step is a step of applying the building finish mixed with water to the surface to be finished, the method of applying the building finish mixed with water is spread by hand, or sprayed through a spray nozzle with airless spray It can be constructed by various methods, which are not limited to any one method.

 The fourth step is a step of curing the applied building finish material at room temperature for 2-3 days. Since the applied building finish material has a liquid phase, the curing step is more firmly attached to the wall, ceiling, and floor. At this time, the curing temperature and time can be changed depending on the thickness of the building finish material, but in general, it is preferable to proceed at room temperature, the time is preferably 2-3 days when the evaporation of moisture is perfect.
