Lightweight solid-state board for building interior with raw ocher as main ingredient and its manufacturing method {THE METHOD OF MAKING LIGHT SOLIDIFICATION-FLAT PANEL WITH MAIM COMPONENT OF RAM YELLOW SOIL FOR CONSTRUCTIVE INTEUOR DECORATION}

The present invention relates to a lightweight solid plate for building interior materials mainly based on fresh clay, and a method of manufacturing the same. Specifically, a mixture of ultra-fine raw clay powder and illite powder, alginic acid concentrate, foaming agent, and foam stabilizer is used for sodium silicate or It is a solidified product which is solidified by impregnating and colliding the colloidal solution, which is added to the aqueous solution of potassium silicate and humectant, and impregnated with a nonwoven fabric of natural fiber. The present invention relates to a lightweight solid plate for building interior materials based on raw clay which can be maintained as

Since the development of synthetic resins, it has been used in various forms from interior materials of buildings made of various synthetic resins for a long time, such as plates, ceilings, synthetic resins, wallpaper or foamed wallpaper, flooring, paint, and adhesives.

Such synthetic resin interior materials are products manufactured by adding various additives in addition to plasticizers and stabilizers to synthetic resins or include volatile solvents.

In recent years, some of the synthetic resins and additives added to them have been found to be harmful to humans, so developed countries have long restricted the use of synthetic resins and additives that are harmful to humans.

Recently, there is a situation in Korea that regulates food packaging materials, containers for building interior materials obtained from synthetic resins, additives added thereto, and harmful solvents that are harmful to humans.

As the harmful substances generated from the interior materials of synthetic resin materials described above, plasticizers, stabilizers, fillers, viscosity regulators, etc. are used when processing PVC, which has been used the most because of excellent processability, and as plasticizers, dioctylphthalate, dibutyl phthalate, and most plasticizers. They are also designated as environmental hormones, and barium and cadmium stabilizers are regulated as heavy metals, and when using solvents in synthetic resin materials, VOC (Volatile Organic Compounds) is generated, which can cause dizziness and headache. It can have a bad effect on the respiratory system and cause skin diseases such as atopy.

In addition, thermoplastic synthetic resins that have been used as building materials have a low heat resistance and flammability, which may cause a fire hazard. In particular, PVC decomposes immediately at a high temperature and generates chlorine gas. It was.

In addition, in the civil engineering field, the amount of use and emptyness of cement can be enormous, but cement is known as a harmful substance to human body. When reclaiming cement waste, leachate contaminates groundwater and drinking water, Due to the concentration, severe bleaching occurs on the seabed near the east coast, making it difficult to inhabit seaweeds and seafood.

In order to cope with the above situation, research and development of synthetic resins and additives without pollution or building materials using natural materials are being actively conducted. Also, the amount of cement in the structure can be reduced by reducing the amount of cement. Structures using natural minerals have been proposed and released, and efforts and means for forming comfortable living spaces using functional materials beneficial to the human body have been proposed. Specific examples of the prior art include Korean registered patent publications (Registration No. 10-814352). No.) introduces "Ondol flooring material using volcanic stone and loess and its manufacturing method" and the contents of the technology, namely, natural flooring material (3), thermosetting adhesive (5), surface layer, jute cloth (1) deposited in binder solution, volcanic stone 35 ~ 45% by weight, 35 ~ 45% by weight ocher, 10 ~ 30% mixed water (2), mixed stone (2), binder Ondol flooring material laminated in the order of jute cloth (1) impregnated with a solution and a method for manufacturing the same, such an ondol flooring material is excellent in warmth and heat insulation, can effectively exhibit the ondol function and a large amount of far-infrared radiation, antibacterial and deodorizing function It may be beneficial to the health of the human body, but first, because it is a layer formed only by the plasticity of ocher by combining water with ocher and volcanic stone for forming mixed stone (2), it is weak in strength and can easily be cracked by ondol heat. If severely dried, ocher particles may be detached and scattered, and thermosetting adhesives are not suitable for environmentally friendly purposes due to the use of solvents.

As another example of the prior art, eco-friendly ocher plate material is introduced in Korea Patent Publication (Publication No. 10-2007-10107), which is the content of the technology, that is, the coating composition of milk state by mixing ocher powder, starch, water, and an aqueous adhesive agent. The liquid composition obtained by adding 5-10% by volume of one functional additive selected from jade powder, activated carbon and stone powder with respect to 100% by volume of this composition was applied to solid wood, MDF, plywood, gypsum board, and metal plate and dried. After that, it is eco-friendly because it uses ocher, jade, activated carbon, and stone powder as a decorative plate formed by forming a printing layer and forming a UV coating layer, but the starch shrinks during drying by using a large amount of starch to form the coating film. Since the crack of the coating layer can easily occur, and the material difference between the inner support plate and the coating layer is large, the difference in the coefficient of thermal expansion is also large. It can be can result in delamination of the coating layer hameuroseo a large shearing force occurs on both the interlayer in accordance with the contraction and expansion.

In addition, cellulose and EVA (Ethylene Vinyl Acetate Resin) are used as aqueous adhesives, but conventional cellulose and EVA are oil-soluble or solvent-soluble resins, and do not dissolve in water. have.

In addition, another eco-friendly indoor and outdoor architectural board is introduced in Korea Patent Publication. It is laminated with woven fabrics (20, 30) of glass fiber as reinforcement on both sides of polyurethane insulation board (10), jade, diatomaceous earth, elvan, germanium, dolomite 85 to 92% by weight of natural minerals, 2.5 to 5% by weight of antifoaming agent, 0.8 to 3% by weight of dispersant (glue), 0.025 to 2% by weight of carboxyl cellulose, 2.6 to 5% by weight of polyvinylacetate (PVAc) By coating with a coating solution obtained by dissolving or dispersing in a large amount of water it can be referred to as an environmentally friendly indoor and outdoor architectural board to form a coating layer (40, 50). By using functional natural minerals such as jade, diatomite, ganban stone, germanium, dolomite (illite), which have various functions that are beneficial to the human body, it can be beneficial to the human body. Problems can arise in the coating composition because the polyvinylacetate, which should be used as a binder of the coating composition, can be reversed to the original environmentally friendly purpose.

As mentioned above, the prior arts are developing various building materials in terms of environment-friendliness using natural materials that are beneficial to the human body, but focusing on eco-friendly purposes, neglecting the original functions and properties as building materials and still need to be improved and supplemented. There is a lot of room.

The present invention provides a lightweight solid plate for building interior materials comprising a raw clay, which supplements the problems of conventional building interior materials, and a manufacturing method thereof, without damaging the function and function of the raw clay containing microorganisms and enzymes beneficial to the human body. It can be preserved as it is, it blocks the odor and toxicity of cement and can be lightened due to its porosity, and it has thermal insulation function, sound insulation function, humidity control, far infrared radiation function, It is an object of the present invention to provide a light-weight solidified plate suitable for wall materials and ceilings mainly composed of fresh ocher having an antibacterial property and an air purifying function due to an excellent deodorizing function and a manufacturing method thereof.

Ultra-fine raw clay powder and elite powder, alginic acid concentrate, foaming agent, and foam stabilizer were added to the aqueous solution of sodium silicate or potassium silicate and wetting agent, and then formed into platelets in stirred colloid. The problem of the present invention can be achieved by manufacturing a lightweight solidified board for interior materials (wall materials, ceiling materials) which is impregnated by impregnating a natural fiber nonwoven fabric or mixed and homogenizing short fibers corresponding to the nonwoven fabric with a colloidal solution.

The built-in foamable lightweight solidified board based on the raw ocher according to the present invention has no high temperature or toxic substances added by firing and drying, so that the function of the raw ocher is maintained without damaging the function of the beneficial microorganisms and various enzymes. It can absorb or decompose and remove odors and toxic substances of cement, and it has deodorant, antibacterial and antifungal properties as well as far-infrared radiation. It also purifies indoor air, keeps warm and soundproof, and has excellent heat resistance. It is possible to reduce the number of bubbles in the tissue of lightweight solids, and these bubbles are connected to natural fibers to maximize the contact surface with the outside air, thereby improving the function of solids, and also using environmentally friendly mineral materials or natural materials. It is lighter in weight than the interior materials, and can reduce weight by 30 ~ 40%. Lightweight solidified board for building interior, which is composed of raw clay which can maintain the interior space of office or house with a variety of functionalities as well as reinforce tensile strength, impact strength, and flexural strength, which are the original properties of solid sheet This can be called.

Recently, it is a complementary invention that improves the problems caused by using large quantity of mineral raw materials and natural materials such as loess to replace building interior materials that cause pollution. Light-weight solidified board for building interior, which is composed mainly of fresh clay with eco-friendly functions and functions while reinforcing and reducing the tensile strength, impact strength and flexural strength of the interior plate (solid) without damaging or losing As a manufacturing method, first, the manufacturing method will be described in detail according to the process. The ultra-fine raw clay powder is 93 to 93.5 wt%, the ultra fine powder 2 to 2.5 wt%, the alginic acid concentrate (solid content basis) 2.5 to 3 wt%, and the foam forming agent 1.5 to 1 step of obtaining a high viscosity colloid by mixing and stirring 2wt%, 0.5 ~ 1wt% bubble stabilizer,

A two-step process of mixing and stirring 1.5-2 parts by weight of an aqueous solution in which 15-20 wt% of sodium silicate or potassium silicate and 1-2 wt% of a wetting agent are dissolved in 1 weight part of the high viscosity colloid,

Fill the container mold with a certain amount of mixed colloid, and then deposit a regular or rectangular nonwoven fabric shaped to match the mold, or insert the nonwoven fabric into the mold first, and then add a certain amount of mixed colloid to disperse and infiltrate it for 30 to 40 minutes. 3 step process to 1st semi-solidification,

And spreading the mixed colloids on the surface of the semi-solidified solid in the container mold to about 1 to 2 mm and then pressing the surface to about 1 to 2 mm from the surface with a pattern forming plate to form a pattern and then completely solidifying and demolding the mold. It can be said to be a manufacturing method of a lightweight solid plate for building interior materials mainly composed of raw ocher.

The particle size of the ultra-fine ocher powder or the illite powder used in the first step in the manufacturing method is finer than 500 mesh, but the particle size is limited by the grinding device and the grinding cost, and the alginate concentrate is 10 wt% Concentrate is used.

Fine oils, soaps, surfactants, and the like may be used as the foaming agent, and fatty acid diethanolamide, CMC, and the like may be used as the bubble stabilizer. Polyol and the like are used as the wetting agent.

The mold used in the three-step process is a regular or rectangular container-type mold release mold, such as a wall plate, a ceiling plate, or a wide-plate-shaped board for interior materials, and the amount of mixed colloids filled in the mold is preformed on the surface of the preformed or rectangular nonwoven fabric. If the amount can be deposited up to, it is possible and allowed to solidify in a free state without applying force from the outside for dispersion penetration. Similarly, when the nonwoven fabric is first inserted into the mold and then the secondary colloid is added, the amount of the mixed colloid is the same and no external pressure is applied.

In this way, in the semi-solidified state, a mixed colloid is applied to the surface of the semi-solid plate to have a thickness of about 1 mm to 2 mm to cover the burial of the protruding nonwoven fabrics, to smooth the surface, and to make the surface layer uncured. The mold is formed by pressing only 1 ~ 2mm about the surface layer to form a pattern.

In some cases, the surface may be decorated by mixing a natural inorganic pigment with the second colloid in a state where the surface is smoothed to print.

In addition, in the three-step process of the present invention, the fiber mixture can be added to the mixed colloids and added to the homogenous amount of short fibers in a homogenized fiber mixture to be treated in the same manner as described below to obtain a semi-solid body.

Looking at the function and features of the raw materials used in the present invention,

Raw clay has beneficial microorganisms, enzymes such as catarase, diphenol oxidase, saccharase, and protease, which remove toxins and detoxify and purify, which can remove the smell and toxicity of cement. It has the function, antibacterial, deodorant, warmth and sound insulation. Also known as eco-friendly building materials, illite is a porous material, which has excellent far-infrared emissivity and also has deodorizing and antibacterial functions. In addition, the foaming agent material forms a myriad of fine bubbles in the mixing and stirring process of the first step, and the bubble stabilizer inhibits the homogeneity of the bubbles and the foaming of the bubbles produced, and the aqueous alginate solution gives the adhesion between tissue particles and the function of the bubble stabilizer. It has good mixing properties with emulsification and prevents phase separation of colloids. Unlike natural adhesives such as glues, it has antioxidant properties and is not easily deteriorated.

In addition, natural fibers improve reinforcement and breathability of lightweight solid plates. Sodium silicate and potassium silicates are solidified by drying while strongly adhering the particles of the colloid mixture. The addition of wetting agents and addition of alginic acid It prevents excessive hardness and imparts impact buffer to the solidified plate.

The built-in foamable lightweight solid plate manufactured by the above method has a myriad of fine bubbles inside the solid plate, and it is excellent in breathability by connecting natural fibers to the micro bubbles and maximizes the contact surface with the outside air. Due to its light weight, the weight can be reduced by 30-40% compared to conventional interior materials made of ocher and functional materials.

In addition, physical properties such as tensile strength, flexural strength, impact strength, and the like are improved compared to conventional materials made of functional minerals.

Such a foamable lightweight solid plate may be referred to as a foamable lightweight solid plate that can be applied to a wall board or a ceiling plate tile.
