Description

Panel using basalt and its manufacturing method {Panel using basalt and its manufacturing method}

The present invention relates to a panel manufacturing method using basalt, and more particularly, by melting basalt or forming a basalt sand (thread) to form a panel, and then coating a flame retardant or resin on one or both sides to form an interior exterior panel of a building Thus, the present invention relates to a panel using basalt and a method of manufacturing the same to provide a basalt panel with enhanced durability, flame retardancy and surface hardness.

Conventionally, a variety of construction materials have been provided that have replaced wood. However, such wood-replaceable recording materials have problems that are vulnerable to heat and fire because all subsidiary materials except metal are made of PVC and synthetic resin.

Therefore, conventionally, construction materials made of synthetic resin were mixed with flame retardant materials or formed by coating a flame retardant material on the surface.However, these building materials decolorize when exposed to sunlight from the outside or continuously receive heat from the inside. There is a falling problem.

In order to solve the above problems, construction materials molded using basalt are still being provided, and construction materials using basalt are not yet activated.

Basalt is a fine-grained volcanic rock that is usually dark gray to black, and is a volcanic rock formed by rapidly cooling off the surface.

Basalt has a porous structure with irregular voids on the surface of the rock, which is a trace of the volatile components contained in the eruption of magma.

Basalt is composed of silica (SiQ2), aluminum oxide (Al2 O3), ferric oxide (Fe2 O3), calcium oxide (CaO), potassium oxide (K 2 O), sodium oxide (NA2 O), and magnesium oxide (MgO). ), etc. It has the property of melting at high temperature.

These basalts are partially used as building materials, but most of them are discarded as waste-rock, and their use conditions are limited.

Looking at the prior art in this field, "Functional architectural decoration material applied with basalt powder" (hereinafter referred to as "prior art 1") of Unexamined Patent Publication No. 10-2009-0011800 (published on February 02, 2009). ① Any action of making quarried basalt into powder, ② Any action of producing a specific type of building material by pressing and heating the basalt refined into powder, and ③ Processing basalt powder.

As another prior art, "Building materials using basalt and its manufacturing method" (hereinafter referred to as "prior art 2") of Patent Publication No. 2002-0096208 (published on December 31, 2002) refers to basalt. Grinding to size;

Injecting the pulverized basalt into a heating furnace and heating it to a melting point or higher to melt the basalt;

Pouring the molten liquid basalt into a mold having a predetermined shape suitable for a purpose, and gradually cooling it in air to form a constant shape basalt plate; And

A configuration including the step of cutting the basalt plate into a predetermined size has been disclosed.

In the prior art 1 and 2, it can be seen that the material is made of basalt and is a building panel.

The prior art 1 is to form a building material by making quarried basalt into powder, then purifying it, pressing, and heating it to form a building material.This is the same technology as the technology of forming an element from metal to powder metallurgy. It is hard like a lump, but in the case of Hyeonmuan, it is formed by cooling a mass of lava.After pulverizing it, put it in a mold and pressurized and heated even if it does not maintain the prescribed compressive strength and tensile strength required for building materials. It is a technology that has failed to be commercialized for use as a building panel because it is used only as an interior and exterior material.

In addition, prior art 2 pulverizes basalt to a certain size, heats the pulverized basalt to a melting point or higher in a heating furnace to melt the basalt, pours it into a mold having a certain shape, and cools it to form a basalt plate. It can be seen that various patterns were formed on the surface of the basalt plate to enhance the aesthetics of the interior or exterior of the building.

That is, both of the prior art 1 and 2 are made to form a plate using basalt and then use it as an interior and exterior material, which can be used as an interior panel inside and outside a building.

These interior and exterior panels do not necessarily require arm axis strength and tensile strength, but only need to satisfy aesthetic factors, and this cannot be used as materials such as interior materials and insulation panels, finishing materials panels, and fire doors used in building construction. There was a problem that it could not be used as a material for construction work because it was used as a panel to be added to other materials even if it was used or used.

Hereinafter, an embodiment of the present invention will be described in detail.

In the basalt panel implemented in the present invention, the main material is made of basalt, and flame retardant coating, thermoplastic resin coating, thermosetting resin coating, melamine resin coating, carbon fiber layer, wallpaper, plaster on one or both surfaces of the basalt panel 10 It is to provide a basalt panel 10 or a basalt insulation panel 40 by forming the surface layer 20 of any one of a board, a wooden panel, a fabric, and a nonwoven fabric.

The basalt panel formed in this way is lighter than conventional cleaning materials, and is easy to handle, and it is made possible by providing a basalt panel or a basalt insulation panel with enhanced waterproof, durability, flame retardancy and surface hardness.

Another embodiment of the manufacturing method of the present invention will be described as follows.

First process: basalt primary crushing and foreign matter screening step

Basalt used in the present invention is a fine-grained volcanic rock that has a dark gray to black color, and refers to a volcanic rock formed by rapidly cooling off the surface of the earth.

Basalt has a porous structure with irregular voids on the surface of the rock, which is a trace of the volatile components contained in the eruption of magma.

Basalt is composed of silica (SiQ2), aluminum oxide (Al2 O3), ferric oxide (Fe2 O3), calcium oxide (CaO), potassium oxide (K 2 O), sodium oxide (NA2 O), and magnesium oxide (MgO). ), etc., and has the property of melting at high temperatures around 1,300℃.

In Korea, basalt, a volcanic ash, is widely distributed in Jeju Island.

In addition, volcanic activities such as Japan and India are currently occurring frequently, and basalt can be easily supplied at low prices.

In the present invention, in order to manufacture a basalt panel, a large lump or the like is first pulverized from the collected basalt panel, and then only grains of 3 mm or more are selected to select foreign substances and powder with low hardness.

In the pulverization process, grains of 3 mm or more and grains of 10 mm, 20 mm, 30 mm, etc. are irregularly crushed. The size of the basalt grains to be crushed is crushed to 50 mm or less, but preferably 10 mm. It is preferable to crush below.

In this process, the basalt mass is crushed and the foreign matter remaining inside the mass and the basalt of low purity are used for other purposes, and only pure basalt material is used.

2nd process: basalt secondary crushing and metal sorting and separation step

The selected basalt pulverized material selected from 3 mm to 50 mm is secondarily pulverized to less than 5 mm.

The basalt pulverized to less than 5 mm is subjected to a magnetic separator to select metal powder and metal material to prepare pure basalt powder.

In order to manufacture the basalt panel or the basalt insulation panel implemented in this process, it is preferable to remove the metallic material.

In other words, the basalt mass is generated by the eruption of lava. Even if there are metallic substances, all of them are in a dissolved state, but if some of them are present in the powder state, electronic problems may occur when using the panel in the future, so the metallic substances are completely removed and pure basalt panels are provided. It is for sake.

3rd process: forming after melting basalt powder in a heating furnace

The selected basalt powder is melted by heating at 1100°C to 1500°C in a heating furnace.

The temperature of the heating furnace for melting the basalt powder differs in the melting temperature according to the external environment and the state of the material of the basalt, but it is preferable to melt the temperature of the heating furnace at 1,300°C.

Step 3: forming a surface layer of basalt panel

The molten liquid basalt is poured into a mold and gradually cooled in air to form an inner body. At this time, a releasing agent is coated on the inner surface of the mold, and a surface layer material is applied thereon, and then a basalt melt is poured and cooled to a rustling state.

In addition, when basalt liquid is injected to form a basalt panel, the amount is injected in consideration of shrinkage during cooling.

Before the inner body 30 of the basalt formed by melting the basalt powder is completely cooled, the material of the surface layer 20 is applied to the upper surface.

The surface layer of the molded basalt panel is formed on the back or both sides, and the material forming the surface layer is a thermoplastic resin coating, thermosetting resin coating, melamine resin coating, carbon fiber layer consisting of any one of polylorepine resin and polyamide resin. , Wallpaper, gypsum board or wood panel.

In this process, the surface layer of the basalt panel may vary depending on the intended use.

For example, when using it as a fire door construction panel and flooring, after molding a basalt panel, a thermoplastic resin coating made of one or both of a polyolefin resin or a polyamide resin, a thermosetting resin coating, a melamine resin coating, and a carbon fiber layer are formed on one or both sides. Therefore, it is selectively used to suit the purpose of use, and when used as interior and exterior materials for buildings, wallpaper made of basalt, non-woven basalt or wooden panels are attached to one or both sides of the basalt panel.

When forming a surface layer on one or both sides of a basalt panel as described above, when the basalt panel is manufactured, the surface is cooled to 50℃-100℃, which is the surface temperature before it is completely cooled. Adhered properly.

At this time, in the case of a resin when forming the surface layer, the resin is uniformly coated and cooled without additional pressure.

In addition, in the present invention, the resin forming the surface layer on one or both sides of the basalt panel includes a flame retardant.

In the present invention, the carbon material forming the surface layer is made of any one of a thermoplastic resin, a carbon fiber, and an inorganic material.

The thermoplastic resin used in the present invention uses a property that causes plastic deformation when heated, but becomes reversibly hard when cooled, and is usually made of a polymer material in a solid state.

In this case, when a polymer compound having a linear structure is heated, it can be transformed into various shapes by revealing plasticity, and when cooled, it hardens while maintaining its shape. When heat is applied again, it becomes soft, and when heated to a high temperature continuously, it becomes a fluid.

In addition, crystalline thermoplastic resins include polyolefin resins and polyamide resins, and are milky white. There are many transparent amorphous thermoplastic resins such as vinyl chloride resin, polystyrene, ABS resin, and acrylic resin. It accounts for about 80% of the total synthetic resin production.

Thermoplastic resins include vinyl chloride resin, acrylic resin, vinyl acetate resin, stycol resin, polyolefin resin, and polyamide resin.

In addition, in the present invention, carbon fibers that are applied to one or both sides of a basalt panel to form a surface layer are carbonized and crystallized by heat-treating organic fibers in an inert gas at an appropriate temperature. The center is polyacrylonitrile (PAN)-based carbon fiber manufactured by carbonizing acrylic fiber as a raw material in an inert state in which chemical reactions such as oxidation, such as oxidation, do not occur at 1,000°C to 1,500°C. In particular, it is highly valuable as a reinforcing fiber for plastic materials.

As another practical example of the present invention, a yarn formed by melting basalt and a nonwoven fabric are heated and pressed to form the inner body 30, and then a thermoplastic resin coating, a thermosetting resin coating, a melamine resin coating, a carbon fiber layer, a wallpaper on one or both sides. , Gypsum board, to form a surface layer 20 of any one of a wooden panel to form a basalt insulation panel 40.

The basalt insulation panel 40 forms an insulation panel using a thread made of basalt material and a nonwoven fabric made of basalt material in order to have a conventional insulation function.

The basalt material for forming the nonwoven fabric is cut to a length of 6 mm or less to form an insulation panel, and then wallpaper or flame retardant resin layers are formed on one or both sides to form a basalt insulation panel.

A basalt insulation panel is formed by forming a surface layer on one or both sides of the insulation panel with a fabric, non-woven fabric, thermoplastic resin coating, thermosetting resin coating, melamine resin coating, carbon fiber layer, wallpaper, gypsum board, or wood panel.

Step 4: forming a coating layer on the surface layer of the basalt panel

The surface layers formed on both sides of one side of the basalt panel of the present invention are formed by applying 0.1 to 5 mm of a resin made of any one of primer, polyurethane, epoxy, and silicone to the surface of the surface layer of the panel, if necessary.

At this time, the coating layer has the effect of protecting the surface of the molded surface layer, preventing discoloration, improving strength and durability, and making the appearance beautiful.

Since the surface layer and the basalt are flame-retardant, they withstand a predetermined temperature in case of a fire, so that it is possible to prevent the fire from spreading rapidly.

Therefore, the film layer coated on the surface layer is filmed with flame retardant, and if necessary, by mixing pigments and filming, it prevents rapid combustion in the event of a fire, and allows the display of single colors or various colors to increase product value. By having a visual effect, it is possible to diversify the field to which the basalt panel is applied.

The silicone coating layer is an organic-inorganic silicone paint having heat resistance of 250°C, cold resistance of -30°C, and flame retardancy, and is preferably coated with 0.1 to 5 mm.

Step 5: Processing and finishing of basalt panels with a surface layer

After forming the surface layer on one or both sides of the basalt panel and finishing processing to manufacture a basalt panel for construction.

That is, after a process such as grinding or cutting the edge portion of the basalt panel manufactured in the above process, it is packaged in a predetermined amount.

The method for molding the basalt panel manufactured as described above can be molded by an extrusion method or an injection method.

To further explain this, first, in the case of the extrusion method, it can be divided into an inner body and an external body. In the case of basalt, it is melted at a predetermined melting point, so the raw material is supplied to the hopper and then melted with the first extruder and supplied to a mold for forming the inner body. At the same time as extrusion, a water support material that forms a surface layer is supplied to another hopper, melted with a second extruder, and supplied to the molding mold.The inner body supplied from the first extruder and the external body supplied from the second extruder are adhered to the surface layer. Basalt panels having a can be molded.

At this time, the thickness of the inner body and the outer body molded in the mold can be selectively adjusted.

In addition, the outer body adhered to the outer surface of the inner body in the mold may be adhered to one or both sides, and the inner body forms a basalt panel, and the outer body constitutes a surface layer formed on one or both sides of the anaerobic panel.

The basalt panel extruded from the mold as described above is completed into a basalt panel having a predetermined standard through a vacuum machine, a cooler, a drawer, and a cutter.

In addition, when the basalt panel is molded using a material that cannot be extruded, it is molded by an injection method, which is molded by an injection method when the basalt insulation panel and the surface layer of the basalt panel are made of carbon fiber material.

There are various injection methods, but for example, after applying a releasing agent to the inner surface of a housing-type mold having a predetermined standard, a resin or carbon fiber that forms a surface layer is applied to a predetermined thickness, and then a solution obtained by melting basalt is poured into the surface. When cooled to a rustling state, resin or tamso fiber is applied again, cooled, and then demolded to form a basalt panel with a surface layer.

At this time, the carbon fibers forming the surface layer are mixed and stirred with a carbon fiber mixture consisting of 5 to 50 parts by weight of the carbon fiber and 10 to 50 parts by weight of inorganic substances per 100 parts by weight of the thermoplastic resin, and then put into a pellet molding extruder and extruded to form a normal pellet. The carbon fiber pellets are formed, and the formed carbon fiber pellets are put into a melter and melted, and then poured to a predetermined thickness on the bottom of the mold or the upper surface of the anaerobic panel to form a carbon fiber surface layer.

After forming the carbon fiber pellets, melting them to form the surface layer of the basalt panel is efficient because of the mixing ratio and ease of handling that the carbon fiber pellets are prepared and then melted to be used as raw materials when producing the basalt panel.

The basalt panel molded in the present invention can be formed in the same size as the conventional interior and exterior materials for buildings, civil engineering materials for wood, sidewalk blocks, plywood, tiles, and the like.

In the above, the extrusion method and the injection method for molding the basalt panel are conventional methods for molding a general PVC panel, and detailed descriptions and drawings are omitted.

In addition, the basalt panel of the present invention manufactured by the above manufacturing method is such that the composite carbon fiber panel has heat resistance at 250°C and cold resistance at -50°C so that it can be used according to the external environmental requirements of industrial sites.

Hereinafter, the accompanying drawings of the present invention will be briefly described as follows.

The resin adhesive used in the present invention is also made of a flame retardant material, and what is referred to as a flame retardant material in the present invention is described on the same basis as the non-flammable material. Therefore, in the present invention, the non-combustible material and the flame-retardant material are not classified and are collectively described as a flame retardant material.

When the flame was injected with the torch lamp, a combustion phenomenon occurred first, and when the flame injection of the torch lamp was stopped, it burned. Is to show that is not progressing.

For reference, the firefighting facility installed in the building, that is, the prinkler, operates within 10 seconds when a fire occurs and the flame comes into contact, and water is sprayed to perform initial extinguishing.

Therefore, in the experiment of the present invention, when the basalt insulation panel 40 is burned with a torch lamp for 30 seconds, it can be seen that the fire does not continue to extinguish and is extinguished, so that the flame retardant effect is sufficient.
