The present invention relates to a method of forming a surface coating layer of mineralized plant fibers, and to building materials and applications thereof. Specifically, minerals obtained by re-coating a curing agent on the surface of a mineral plant construction material manufactured by mixing a plant yarn and a curing agent. The present invention relates to the formation of surface coating layers of plant fiber construction materials and their applications.

The initial pastoral resin panel, which is made by thinly slicing wood and mixed with inorganic or cement such as glue, resin, gypsum, magnesium, and pressed, is pressed into a panel form, and is easier to install than other existing methods such as brick masonry. It has various advantages such as sound absorption and humidity control, but it absorbs water for a long time, so it has a submerged deformation such as disintegration of shape, and it does not meet the real market demand such as fire resistance, weather resistance, corrosion resistance, and mass production. I just gathered it. In addition, resins emit toxic gases during high-temperature combustion such as fires, and adversely affect the environment and human health.

In order to improve the initial pastoral resin panel as described above, the pastor cement panel has been introduced to improve the fire resistance, water resistance, weather resistance, corrosion resistance, and chemical resistance by adding a small amount of inorganic minerals to cement. However, the pastor cement panel uses a large amount of cement to enhance the molding effect, and the fire resistance is basically dependent on the fire resistance of the cement itself, and the fire protection performance of the product is ideal because the wood fiber itself is not flame retarded. There is a problem. In addition, the large amount of cement fills the atypical cavity structure, which is formed by stirring with the pastor, and heat and sound are transmitted through the cement to reduce the effects of insulation, insulation, sound absorption, and sound insulation. There is a problem in that handling is inconvenient, there is a risk of deformation and the color is darkened due to cement. In addition, cement has a problem that cracks occur and strength is weakened when exposed to high heat of 1000 ° C. or more. Hardening agents of cements are severely hampered by the effects of sugar and wood nitrogen in plant materials. Therefore, the choice of plant material source and the strength of the products made are not only limited, but the processing of raw materials is required separately. This leads to an increase in manufacturing cost.

In order to solve this problem, Korean Patent Application No. 2005-0000000 filed by the applicant has a calcium carbonate, calcium chloride, calcium silicate, calcium oxide, magnesium oxide, magnesium chloride, magnesium sulfate, iron oxide, aluminum oxide, aluminum silicate, silicon dioxide, Mineral minerals with high fire resistance such as pearl rock, haemulseok, super gemstone, and kaolin are used as hardeners to disclose mineralization plant construction materials with excellent fire resistance, water resistance, weather resistance, corrosion resistance, chemical resistance, and non-toxicity.

However, the mineralized plant yarn building materials have a rough surface, resulting in inferior aesthetics, sound insulation, waterproofness, and fire resistance, and are inconvenient to have a separate finish on the surface. The additional weight of raw materials increases the weight and does not meet the surface flatness and size specifications required by the market.In addition, the surface smoothness of the products added with chemical adhesives to gypsum, wood chips or sawdust has been improved. Due to its properties and processing method, there is a problem such as uncomfortable construction and increased cost because it needs to be reinforced with fireproof interior materials when it is actually used due to insufficient fire resistance, water resistance, insulation and non-toxicity.

 Existing mineralized plant yarn panels, pastor cement boards, or plant fiber cement boards are not only used for wall or roof materials that are emphasized at the same time as light weight, fire protection and aspiration characteristics, but also general interior and exterior materials, ceiling materials, floor materials, walls, It is inconvenient to be used for prefabricated partitions, integral formwork, wooden columns and beams. In order to finish using sheet, cloth, wall paper, etc., add surface treatment or boards with fire resistance or sound insulation. There is a problem such as adding a. In addition, there is a problem that fire, moisture, and noise can penetrate into the gap formed by the plant fiber while being stirred, so that fire resistance, water resistance, and sound insulation are inferior.

The present invention has been made to solve the above problems to form a smooth surface and easy to finish, and provides a mineralized plant fiber building material excellent in fire resistance, waterproof, sound insulation, weather resistance, substantially the interior of the building. It is intended to be used for exteriors, ceilings, walls, floors, prefabricated partitions, integrated formwork, wooden beams and columns.

The present invention is to cut or pulverize at least one or more of the plant material of wood, palm fiber, palm fiber, cotton stem, bamboo, herbaceous plants, nut shells, shells of peas to a predetermined size to make a plant sand, calcium carbonate, calcium chloride, silicic acid A hardener in which at least one mineral material of calcium, calcium oxide, magnesium oxide, magnesium chloride, magnesium sulfate, iron oxide, aluminum oxide, aluminum silicate, silicon dioxide, pearlite, calcite stone, gemstone and kaolin is mixed with water is added to the plant yarn.

Hereinafter, various embodiments of the present invention will be described as an integrated formwork for a concrete slab for reducing the noise between floors of a multi-family house, a building interior plate, a non-bearing inner and outer wall of a building, and a prefabricated partition.

<First Embodiment>

First, a first embodiment of the present invention using a mineralized plant fiber panel having a surface coating layer as an integrated formwork for concrete slabs to reduce noise between floors of a multi-family house will be described.

The mineralized plant fiber board with the surface coating layer to be used as an integrated formwork for concrete slabs has a thickness of about 35mm, and the lower side is smoothed by applying a hardener, and the upper side is manufactured to maintain the rough surface. This allows the rough surface of the upper side to be combined with the concrete to be more integrated, and the absorption of vibration and impact sound is increased, and the lower side where the coating layer is formed is exposed to the outside to provide sound insulation, and watertightness to provide wet curing and insulation of concrete. This is because it helps cure and strengthens fire resistance. The smooth underside is exposed to the outside for easy finishing.

The mineralized plant fiber board having the surface coating layer manufactured as described above is placed on the floor, and the concrete is poured after weaving steel bars on the upper side thereof. At this time, the mineralized plant fiber board has excellent sound insulation, sound absorption, shockproof, watertightness, fire resistance, and is integrally formed with concrete, so that the thickness of the concrete is reduced to about 150 mm or more from 180 mm, the thickness of the standard floor structure, to about 30 mm. . Next, the insulation and the cushioning material are placed on the upper side with a thickness of 20 mm or more, and the lightweight foamed concrete is poured on the upper side by 55 mm or more, and then the finishing mortar is constructed over 20 mm. When the mineralized plant fiber board having the surface coating layer of the present invention is used as an integrated formwork for concrete slabs as described above, the thickness of the concrete can be reduced while the overall floor thickness is the same as the standard floor structure, thereby reducing the load on the building. It has the effect of being excellent in sound, sound absorption, watertightness, fire resistance, shockproof and heat insulation insulation. In addition, unlike the deck plate, which is an integral formwork made of metal, woodworking tools can be used as it is, so it is easy to install and modify wiring and piping. In addition, the surface exposed to the lower side is smooth, there is an effect that it is easy to install wallpaper, tiles and the like.

Second Embodiment

Next, a second embodiment of the present invention using the mineralized plant fiber board having a surface coating layer formed therein will be described.

The mineralized plant fiber board with the coating layer to be used as the fireproof interior material of the building has a thickness of about 2.7mm to 21mm depending on the thickness of plywood, MDF, OSB, and particle board which are commonly used, and the thickness within about 1mm on both surfaces Apply the curing agent thinly and make it to keep the surface smooth. When the mineralized plant fiber board formed with the surface coating layer of the present invention as described above is used as the interior material of the building, the problems of the existing wood-based boards, such as fire resistance, water resistance, water resistance, corrosion resistance, sound insulation and non-toxicity, can be solved. There is an effect that can omit additional work to reinforce these necessary properties separately. In addition, the surface exposed to the outside is smooth, it is easy to finish the decoration sheet, wallpaper, tiles, paint, and the like.

Third Embodiment

An example of using a mineralized plant fiber board having a surface coating layer as a third embodiment of the present invention as a non-bearing wall for prefabricated interior and exterior walls of a building will be described.

Mineralized plant fiber boards with surface coatings for use as prefabricated inner and outer walls for non-bearing walls have a thickness of about 80 mm, and a hardening agent is applied to each surface to have a thickness of about 10 mm to maintain a relatively thick surface coating layer. . This is to make the wall which is the fireproof structure for 2 hours or more as the board itself without extra surface treatment, and to maximize the waterproofness and weather resistance.

The mineralized plant fiber board with the coating layer formed as described above is a reinforcing tape or cement mortar for preventing crack cracking separately after prefabricated wall construction required by the existing wall construction method using the existing pastor cement board or the mineralized plant yarn panel. Reinforcement work such as wire mesh for coating and cement mortar application on both sides necessary for imparting fire resistance and wall surface treatment for surface finishing are omitted, or existing pastor cement board or mineralized plant yarn panel is omitted. It is necessary to attach gypsum board, magnesium board, calcium silicate board, etc., which is one method that can be considered to reinforce or realize the necessary characteristics such as fire resistance and water resistance, in advance by compounding the panel or attaching it to a wall separately by field construction. The board attached to the outside is peeled off during absorption or fire. Phenomenon can also be prevented, and compared with the existing wall construction method, the weight reduction and wall space reduction can be achieved. Accordingly, the construction is completed only by dry assembly, so the construction method is simple, which can shorten the air, reduce the building load, and install the board with excellent sound insulation, waterproof, fire resistance, weather resistance, non-toxicity and surface beauty. There is also an effect that can be used as a wall without the exterior finish itself. In addition, the smooth exposed surface makes it easy to install finishing materials such as cloth, wallpaper, tiles, paint, and decoration sheets without additional surface treatment, and it is also easy to install various exterior panels such as stone and aluminum materials due to sufficient strength. In the case of reinforcing the thermal insulating material, it is also possible to consider a method of reinforcing the thermal insulating material between two layers of mineralized plant fiber board having a coating layer formed on one surface thereof to face the outer layer.

Fourth Example

The use of a mineralized plant fiber panel having a surface coating layer as a prefabricated fireproof partition of a building will be described.

The mineralized plant fiber panel with the surface coating layer used as the prefabricated fire-proof partition has a thickness of about 21mm to 35mm, and is finished by applying a curing agent to both surfaces to smooth and attaching a flame-retardant decoration sheet on it. By processing, only the assembly in the field is produced to complete the installation of the partition without additional finishing. When the mineralized plant fiber board having the surface coating layer formed as described above is used as a prefabricated partition, there is an effect of ensuring sound resistance and fire resistance while having excellent sound insulation and fire resistance without a separate finishing process only in the field. In addition, it is easy to work with a beautiful and smooth surface of the coating layer even if a separate finish, such as decoration sheet, wallpaper, cloth, sound absorbing material, etc. in the field instead of the finished partition.

As described above, the mineralized plant fiber building material having the surface coating layer formed by the formation of the surface coating layer of the mineralized plant fiber of the present invention and its application is substantially made of interior and exterior materials of the building, ceiling material, wall, floor material, prefabricated partition, It can be used for various purposes such as integrated formwork, wooden beams and columns, and the construction is simple and has the effect of reducing the construction cost, manpower and time. In addition, the surface is formed smoothly, it is very easy to follow-up finishing process such as sheet, cloth, wallpaper, tile, paint, exterior panel. And the surface layer has the effect of excellent fire resistance, water resistance, sound insulation, weather resistance, corrosion resistance.
