Description

Environmental interior and exterior finishing Panel for Friendly Environment and manufacturing method

The present invention relates to a finishing panel of a building and a method of manufacturing the same, and more particularly, to an environment-friendly interior and exterior finishing panel having a diatomaceous earth layer and a multilayer structure of a composite natural material layer of diatomaceous earth and other natural materials. will be.

In general, the wall finishing material of the building is an exterior finishing material (outer wall finishing material) made of a panel added by processing stone or marble to make the exterior of the building look beautiful on the outer surface (outer wall) centered on the wall made by curing cement mortar. It is divided into wall coverings with various pattern shapes or interior finishing materials (synthetic finishing materials) made of synthetic resin and wood panels to create indoor atmosphere and indoor environment.

Since the interior and exterior finishing materials, in particular, interior finishing materials that create the atmosphere and interior environment of the interior are formed in a space where a person lives, it is above all to use a material that does not harm the human body and keeps the living environment in a comfortable state. It is important. In other words, since the interior is a closed space, various odors and molds are generated, so the use of a finishing material having self-cleaning ability such as air purification is required.

However, gypsum board, plywood, etc., which are generally used, manufacture a product by molding a mold using a chemical adhesive and then plastically processing it to a specific shape and shape at a high temperature. It has not been provided at all, and because it provides only the functionality as a building structure or interior and exterior finishing materials, and emits wind materials and toxic gases called radom, there is an urgent need for the multifunctionalization of such building materials.

In order to solve the problems of the related art, in recent years, far-infrared rays are emitted, and internal finishing materials based on environmentally friendly ocher are often used, but this is not beautiful because the cracks occur as it dries, harming the indoor environment and causing moisture. When absorbed, there was a problem that the ocher powder is buried in clothes.

Therefore, as the interior and exterior finishing materials of various buildings, research on materials that are environmentally friendly and beneficial to the human body is provided with breathability, insect repellent effect, humidity control, heat insulation, sound insulation effect, and deodorizing power. Diatomaceous earth is attracting attention as an excellent material.

Diatomaceous earth is a fossilized single-celled plant called diatoms that originated from the dinosaur age about 100 million years ago due to crustal changes and climate changes in the lake or sea. More than 90% is amorphous. It is made of silica (SiO ₂ ), which is a physicochemically stable inorganic material, and there are countless small pores on the surface to remove organic matters in the pores, and to maximize the surface area.

Therefore, diatomaceous earth can play the role of adsorption and filtration of harmful substances in the air to filter out impurities in the room, and it protects the heat in the room because of its thermal insulation, and it works deep inside the body by the release of negative ions and far infrared rays. It warms up, promotes blood circulation, helps to recover from fatigue, and releases waste products, and makes the body energetic.Negative ions absorb and neutralize the cations in diatomaceous earth, which are rapidly increased due to various pollutions. Makes you want

In addition, since diatomaceous earth has many pores, it absorbs moisture when it is humid and diverges when it dries, and it absorbs and diverges moisture repeatedly while sleeping, causing people to get a good night's sleep. And absorbs various pollutants to protect the human body from harmful electromagnetic waves. In addition, diatomaceous earth prevents decay and deodorizes, thereby adsorbing various harmful microorganisms and odors, thereby preventing decay, as well as deodorizing / preserving effects.

Attempts have already been made to use diatomaceous earth as interior and exterior materials for buildings. Korean Patent Laid-Open Publication No. 2000-0030666, Patent No. 2004-0021219, and Patent No. 10-0814899, etc., propose a composition in the form of powder, etc., in which diatomaceous earth is the main component, and the composition is coated on an existing finish in the form of a spray. The way it is. However, in the case of simply coating like these, it is very weak to make use of the original characteristics of diatomaceous earth, and the hardness of the coating layer is weak, so that the coating layer is damaged or peeled off, thus losing its function and having a poor appearance.

In order to solve the problems of the prior art pointed out above, the present invention is an eco-friendly interior and exterior finish of a multi-layer structure that fully exhibits the characteristics of diatomaceous earth excellent in air self-cleaning ability, breathability, insect repellent effect, humidity control, heat insulation, sound insulation effect, deodorizing power The purpose is to provide a panel.

Still another object of the present invention is to provide an environment-friendly interior and exterior finishing panel having a multilayer structure having sufficient strength while maintaining all of the above functions and achieving excellent durability.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the following description is only a detailed description to help understand the present invention, it is apparent from the position of those skilled in the art that the following description does not limit the scope of the patent.

According to a preferred embodiment of the present invention, the environmentally friendly interior and exterior finishing panel of the present invention is a laminated structure of Figure 1, that is, a diatomaceous earth layer (1); A glass fiber layer 2; Composite natural material layer (3); And the nonwoven fabric layer 4.

Diatomaceous earth layer 1 is prepared by mixing and stirring diatomaceous earth and water. Natural mortar may also be added to the diatomaceous earth to coagulate. The diatomaceous earth used in the present invention preferably has a particle size of 125 to 320 mesh. The reason why the diatomaceous earth is 125 to 320 meshes is because the diatomaceous earth of the particle size can maintain an even wall surface and is excellent in workability. In addition, since the diatomaceous earth occupies the outside of the panel, the effect of plastering is also exhibited.

Diatomaceous earth is a fossilized single-celled plant called diatoms that originated from the dinosaur age about 100 million years ago due to crustal changes and climate changes in the lake or sea. More than 90% is amorphous. It is made of silica (SiO ₂ ), which is a physicochemically stable inorganic material, and there are countless small pores on the surface to remove organic matters in the pores, and to maximize the surface area.

Therefore, diatomaceous earth can play the role of adsorption and filtration of harmful substances in the air to filter out impurities in the room, and it protects the heat in the room because of its thermal insulation, and it works deep inside the body by the release of negative ions and far infrared rays. It warms up, promotes blood circulation, helps to recover from fatigue, and releases waste products, and makes the body energetic.Negative ions absorb and neutralize the cations in diatomaceous earth, which are rapidly increased due to various pollutions.

In addition, because diatomaceous earth has many pores, it absorbs moisture when the surroundings are humid and diverges when it is dry, so that the person repeatedly sleeps and absorbs moisture while sleeping. It absorbs electromagnetic waves and various pollutants to protect human body from harmful electromagnetic waves. In addition, diatomaceous earth prevents decay and deodorizes, thereby adsorbing various harmful microorganisms and odors, thereby preventing decay, as well as deodorizing / preserving effects.

The present invention is a panel structure in which a diatomaceous earth layer (1) and a composite natural material layer (3) to be described below are divided to form a multilayer. This is an important feature of the present invention as distinguished from the prior art. When only the composite natural material layer is composed, the diatomite's natural air purification function is discolored in the process of mixing with other materials. Therefore, the diatomite only layer is separated from the composite natural material layer and the surface of the finishing material (the panel is attached On the back side of the face.

In addition, the inventors have found through repeated experiments that this can ensure sufficient hardness. The composite natural material layer contains ocher and the like, which causes shrinkage during curing and drying, and has poor dimensional stability against temperature and humidity changes, resulting in cracking and sagging. However, when the diatomaceous earth layer is placed on the surface of the finish panel, the dimensional stability of the panel against temperature and humidity changes can be secured while maintaining the function of the composite natural material layer, that is, the hardness of the material can be expressed. It also adds durability to eco-friendly finish panels.

The glass fiber layer 2 is stacked on top of the diatomaceous earth layer 1 and serves to distinguish the composite natural material layer and the diatomaceous earth layer. The reason why the glass fiber 2 is used for the distinction between the two is to consider the hardness of the entire panel and to increase the tensile strength and increase the adhesive strength by using the reticulated glass fiber.

The composite natural material layer 3 is laminated on the glass fiber. Composite natural material layer of the present invention is prepared by mixing (38) diatomaceous earth 38 ~ 57wt%, pumice 30 ~ 45wt%, ocher 10 ~ 22wt%, germanium 2 ~ 10wt% in the form of powder and mixed with water. In this case it can be prepared by mixing together the natural mortar. Also, in some cases, jade or elvan can be further added to ensure better functionality.

 In this case, the diatomaceous earth is a particle of 125 ~ 320 mesh and add 38 ~ 57wt% of the total mixed powder mass. The reason why the diatomaceous earth is 125 to 320 meshes is because the diatomaceous earth of the particle size can maintain an even wall surface and is excellent in workability.

Pumice is also called pumice and pumice stone. It has a small specific gravity and is light enough to float on water. This characteristic is due to the fact that when the magma is released into the atmosphere, a sudden decrease in pressure results in the escape of volatile components in the magma resulting in numerous pores. This pumice originates from acidic magma, which contains some semicrystalline minerals, but most are glassy. Pumice is used for pumice concrete and is mainly used for structural concrete in construction. In addition, it is light and has low thermal conductivity, so it is used as aggregate for roof, bingo, bathtub, and other heat shield concrete.

Since the pumice stone in the present invention is considerably light in weight, it greatly contributes to lightening the weight of the entire panel, and numerous pores have air permeability, heat insulation, and air purification ability. The pumice stone is 125 to 250 mesh particles and 30 to 45 wt% of the total mixed powder mass is added.

Ocher is a honeycomb structure with a large surface, and a large number of spaces have a multi-layer structure. In this sponge-like hole, far-infrared rays are absorbed and stored in a large amount, and radiate when heated to stimulate molecular activity of other objects. In particular, the loess of our country is known to generate far infrared rays with a wavelength of 6 to 15 μm, and also has insect repellent properties against insects and insects, good heat storage, good deodorizing effect, and various positive effects on human health. It has been found to have a phosphorus effect. In the present invention, the ocher is a particle of 125 ~ 320 mesh and add 10 ~ 22wt% of the total mixed powder mass.

Germanium is one of the carbon group elements belonging to group 4B of the periodic table and has the element symbol Ge, atomic number 32, and atomic weight 72. The anionic oxygen surrounding germanium is known to have an effect of neutralizing heavy metals and heavy chemical components by interacting with hydrogen having acidic properties as a cation. In the present invention, germanium is a particle of 125 ~ 300 mesh and add 2 ~ 10wt% of the total mixed powder mass.

In the composite natural material layer 3, jade or elvan may be further added to increase the functionality of the present invention.

Elvanite is composed of 30,000 to 150,000 multi-layered porous materials per cubic centimeter, and has a large specific surface area to adsorb and decompose pollutants and heavy metals, and also exhibits neutralization of cement toxicity, antibacterial, insect repellent, and strong deodorizing ability. It is known to have an excellent effect on maintaining freshness of food, increasing taste, promoting blood circulation and metabolism due to resonance resonance and absorption by radiation. In the present invention, the elvan is used as the particles of 125 to 300 mesh and may add 2 to 10 wt% of the total mixed powder mass.

Jade contains minerals, calcium and magnesium that are extremely necessary for the human body, and magnesium accounts for more than 40% of its components. In the case of jade, it is known that the wave generated from jade and the wave of human cells are the same wave. Therefore, there is a research report that the wave emitted from the jade evenly penetrates the human body cells and has the function of resonant resonance, thereby reviving the tissue, circulating the thermal fluid, weakly alkaline the blood, and excretion of harmful wastes in the body. In the present invention, jade may be 125 to 320 mesh particles, and 8 to 20 wt% of the total mixed powder mass may be added.

The nonwoven fabric layer 4 is laminated on the composite natural material layer 3. In this case, the nonwoven fabric uses a nonwoven fabric used as a general building material. This part becomes a part to be constructed on the wall surface.
