Description

Noncombustible panel for construction

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a building panel, and in particular, foamed pearlite which forms pores by foaming pearlite ore, pulp that gives high tensile strength, gypsum powder that gives high compressive strength, and adhesives for fillers. After mixing the loess, which is compressed, the mixture is molded into a mold and dried to form a panel filler which is provided in a cured state, and the outer panel is attached through a non-combustible adhesive applied to one or both sides of the panel filler. As one of them, it has high tensile strength and compressive strength as well as improves the adhesion of panel fillers to make high-strength panels, and since the fillers are eco-friendly non-combustible materials, it can reduce human injury by preventing the emission of toxic gases in case of fire. In addition, it is possible to prevent the degradation of the thermal insulation and sound insulation function due to deterioration of the panel filler. In addition, it is possible to eliminate the disadvantages of pollution of the human body and living environment, to prevent environmental pollution during disposal, and to reduce the cost of disposal, and to use an adhesive that does not soften for a certain time at high temperature. Therefore, the outer panel is prevented from being separated from the panel filler in a high temperature state and relates to a non-combustible building panel that can slow down the collapse speed of the building as much as possible.

In general, a widely used building panel is used as a filler, and various materials such as flame retardant synthetic resin fiber, foamed resin board, stone, glass fiber, outer panel, loess, ceramic material, cork, gypsum, and the like are used as the filler.

In particular, building panels using organic materials mixed with foamed resins are widely used to improve insulation and sound absorption, have low hygroscopicity, and workability. Examples thereof include foamed polystyrene and foamed polyurethane, which are chemically synthesized styrofoam. , Expanded vinyl chloride, and other plastics.

However, such organic building panels are weak in heat and do not delay the collapse of the building, and thus have a disadvantage in that they cannot get time for fire suppression and have a weak strength. They cannot be used independently and must be used in combination with other materials. There is this. In addition, in the event of fire, toxic gas is emitted to cause a lot of casualties, and as the time passes, the material of the filler deteriorates and the function of insulation, sound insulation, etc. is deteriorated. It has the problem of environmental pollution.

Therefore, in order to solve some of the above problems, flame retardant synthetic resins have been used as panel fillers. However, this does not solve the conventional problem because it also burns when it fails to extinguish initial fire and reaches near 1,000 ℃. I can't. In addition, to compensate for the deterioration of the panel filler easily, as described above, stone, ceramic materials, etc. are used, but this is also strong in heat, but its weight is heavy and sound insulation and heat insulation effects are not sufficiently achieved.

In addition, there have been attempts to achieve non-combustibility, soundproofing, and insulation effects by using glass fibers as panel fillers.However, the glass fibers are suspended in the air as they are suspended in the air during manufacture and installation. There is a problem that the fine glass fiber is continuously discharged from the panel after being sucked into the human body through the installation and causing pollution of the human body and living environment.

In order to solve the problems of the conventional panel fillers, mineral materials such as pearlite are pulverized and foamed, and then inorganic binders are filled and used as panel fillers. However, since the foamed pearlite is combined with the inorganic binder in the form of a pulverized product, its weight is light, but the compressive strength and the tensile strength are weak, and the bonding strength of the fillers is weak.

Therefore, the organic binder is used to increase the bonding strength between the fillers or the plate is attached to the outside of the panel filler to increase the strength of the panel, but the organic binder is also composed of an organic compound, The adhesive applied for the use also uses an organic adhesive. In case of fire, the toxic gas emitted when the binder for the organic filler and the adhesive for attaching the plate are burned, there is a risk of injury to the human body. Due to the separation from the filler there is a problem that the strength of the building is sharply lowered leading to collapse.

On the other hand, in order to solve this problem, it may be used by adopting an inorganic binder, the binder can prevent the generation of toxic gas to some extent, but the disadvantage that it becomes difficult to form a panel product.

As a result, conventionally used building panel fillers provide non-flammable, flame-retardant, tensile strength, compressive strength, flame-retardant adhesives, and do not include all of the functions as eco-friendly materials and solve only a few problems. There is an urgent need for building panels to solve at once.

The present invention has been made in order to solve the problems of the conventional building panel, the pulp, gypsum powder and loess have an organic relationship with each other to be a non-combustible panel for long-lasting high temperature, high tensile strength And compressive strength and sufficient adhesive strength of panel fillers to make high-strength panel fillers, and use them as fillers and adhesives with only eco-friendly non-combustible materials to prevent the emission of toxic gases in the event of fire, thereby reducing human injury and deteriorating panel fillers. It prevents the deterioration of the thermal insulation and sound insulation functions and prevents pollution of the human body and living environment. In addition, it prevents environmental pollution and reduces the cost of disposal, and prevents separation of panel fillers and external panels at high temperatures by using non-flammable adhesives. Its purpose is to provide building panels.

In order to achieve the above object, the incombustible building panel of the present invention is a building panel filled with a foamed pearlite pulverized product and an inorganic binder, wherein the pearlite ore is crushed and heated to form pores, and then cooled perlite Foamed pearlite (2) with additional pores by rapidly releasing gemstones from high pressure to low pressure, pulp (3) completely dried to give high tensile strength, and completely dried to give high compressive strength The gypsum powder (4) and the ocher (5) in a state containing a small amount of water in order to act as an adhesive of the fillers are mixed by compression processing inside the mold and then dried by the panel filler in the hardened state (1) Characterized in having a.

As described above, the incombustible building panel of the present invention has a high tensile strength and a compressive strength corresponding to a conventional building panel, as well as improved adhesion of panel fillers to make a high strength panel, and the fillers are all environmentally friendly. As it is a non-combustible material, it can prevent the emission of toxic gas in case of fire and reduce the damage to human life.It can prevent the degradation of the insulation and sound insulation function due to deterioration of panel filler, and also eliminate the disadvantages that cause pollution of human body and living environment. Can be.

In addition, it is possible to prevent environmental pollution and to reduce the cost of disposal, and to prevent the external panel from being separated from the panel filler in high temperature state by using a non-flammable adhesive to maximize the decay rate of the building. You can slow it down.

As shown, the non-flammable building panel according to a preferred embodiment of the present invention, after forming the pores by pulverizing and heating the pearlite ore, foamed to have additional pores by rapidly releasing the cooled pearlite ore at high pressure at low pressure To serve as an adhesive for the pearlite (2), the pulp (3) completely dried to impart high tensile strength, the gypsum powder (4) to be completely dried to impart high compressive strength, and In order to mix the ocher (5) in a state containing a small amount of water to the compression process inside the mold and then dried and consists of a panel filler (1) of the cured state. In addition, various non-combustible outer panels 7 and 7 'may be formed on one or both surfaces of the panel filler 1 by pressing or attaching to each other by a method such as bolts, screws or rivets. In addition, the non-combustible adhesives 6 and 6 'are applied to one or both surfaces of the panel filler 1, and the various non-combustible outer panels 7 and 7' are applied to the non-combustible adhesives 6 and 6 '. It can also be configured.

Hereinafter, the characteristics and functions of the foamed pearlite 2, the pulp 3, the gypsum powder 4, and the loess 5 forming the panel filler 1 will be briefly described as follows.

The foamed pearlite (2), but using a volcanic stone corresponding to the foamed pearlite ore, the type of obsidian, pearl rock, pine rock, etc., and is divided according to the appearance and volatile components, the pearlite heat insulation, heat insulation, sound absorption It is used for such purposes and is widely used as aggregate for filling, mortar and plaster.

The pearlite forms a myriad of pores, has a small weight to volume, and has low thermal conductivity, thereby providing excellent thermal insulation. In addition, the chemically neutral non-flammable inorganic material is not toxic gas generation at the time of fire, as well as a material that is safe enough to be approved for food additives material is suitable as an environmentally friendly material of the present invention.

The pulp (3) is a collection of cellulose fibers obtained by mechanical, chemical or intermediate methods in wood or other fiber plants, except bark and stems of rice and plants, bark such as hemp, and branches and leaves of trees. There are many types of pulp, such as stems, which can be selectively added depending on the application range and application.

In addition, when the pulp (3) is classified according to the raw material, it is divided into wood pulp and non-wood pulp, wood pulp is further divided into conifer pulp (NP), leaf pulp (LP), the non-wood pulp is straw pulp (straw pulp), bagasse pulp (bagasse pulp), reed pulp, bamboo pulp, bast fiber pulp, rag pulp, cotton pulp and the like, in the present invention can be selectively used in the various types described above.

In particular, when the pulp (3) is used as a panel filler for the non-dispersion axis according to the present invention, the pulp (3) gives a unique tensile strength, and the weight of the pulp (3) itself light weight panel filler ( Can make 1).

On the other hand, because the pulp (3) is a material that burns well, it may be easily burned, but in the event of a fire, foamed pearlite (2), gypsum powder (4), ocher (5) is mixed with the pulp (3). In this state, the foamed pearlite (2), the gypsum powder (4), and the yellow soil (5) prevent the pulp (3) from directly contacting the air so that the pulp (3) itself does not soften directly. That is, since the softening of the panel filler 1 starts after about 3 hours even at a high temperature of 800 to 1,200 degrees Celsius, it provides sufficient time to extinguish a fire.

These results could be confirmed through experiments, and even if the chart does not describe the evidence, the foamed pearlite (2), gypsum powder (4), ocher (5) can be sufficiently predicted because it is a flame retardant material.

Therefore, by providing a high tensile strength that the panel filler (1) made of a conventional pearlite and inorganic binder does not have, the cracks do not easily occur even by the difference in humidity according to the irregular ambient diameter or the load or external impact of the building. This long and semi permanently available panel is provided.

The gypsum powder 4 is a mineral widely used in various fields because of its wide distribution and low cost. In particular, the gypsum powder 4 is used as a mixture of cement, fertilizer, and white pigment, and is baked and calcined into a plaster, a material, a modeling material of a casting, and a medical cast. As it is used as a heat insulator, it is widely used for gypsum board which is a general building insulation.

In this case, when used as the gypsum board is attached to the wall or ceiling and acts as a fire-retardant, and the sound-absorbing board is acoustically absorbent, and the decorative plaster board coated or printed on the surface is used as interior materials. In particular, since the gypsum powder 4 has a large compressive strength, when used as a filler of the incombustible building panel of the present invention, the gypsum powder 4 has a function of distributing the load of a building to prevent breakage of the panel by external load.

Meanwhile, vermiculite, which has various uses as a soundproof material, a heat insulating material, a heat insulating material, a lightening material, a soil improving agent, and a top soil agent, may be used instead of the gypsum. In other words, the vermiculite powder provides the compressive strength provided by the gypsum so as to diversify the material used.

Of course, since the vermiculite has a plurality of pores and expands at a high temperature, it is preferable to first heat it to a high temperature and expand it to form a powder to be processed to have a high compressive strength. Like gypsum, it is possible to provide high density compressive strength.

The ocher (5) is a well-known fact that it blocks harmful waves, such as water veins, and far-infrared rays, which are beneficial to the human body, are beneficial and environmentally friendly materials for the human body. Therefore, when used as a filler does not generate harmful substances, there is an advantage that there is no problem of environmental pollution when discarding the panel filler (1).

In particular, the ocher (5) has a strong adhesive strength when mixed with other fillers in a state containing a small amount of water and dried. Therefore, it is used as the adhesive (6, 6 ') of the panel filler (1) according to the present invention, in which a plurality of pores formed in the foamed pearlite (2) is dried in the state of entering the ocher foamed pearlite (2), pulp ( 3), it provides a strong adhesive force in the mixed state with the gypsum powder (4).

Hereinafter, the manufacturing process of the present invention having the above-described configuration will be described.

First, the pearlite ore is crushed and the pulverized product is subjected to a heating process for a predetermined time to 900 ~ 1200 ℃ and then undergoes a cooling process. At this time, a plurality of pores are formed in the pearlite pulverized itself and is heated to a high temperature and then cooled, thereby making a foamed pearlite 2 having a high number of pores and a high strength.

Next, by rapidly releasing the pulverized foamed pearlite (2) having a plurality of pores formed from a high pressure state to a low pressure state, additional pores are formed between the pearlite particles to expand the expanded pearlite having more pores than the pores formed in the heating step. (2) is made.

As described above, the reason why a large number of pores are formed is that the pearlite gemstone contains 3 to 4% of volatile components, and when the pearlite having such properties is finely pulverized and suddenly heated, the volatile components contained therein expand inside. The internal pores are formed to expand about 10 to 20 times the original volume and has a light specific gravity.

Next, the mixture of foamed pearlite (2) 60 to 80%, pulp (3) 8 to 15%, gypsum powder (4) 8 to 15%, ocher (5) 4 to 10% by weight to make a mixture. . At this time, since the small amount of moisture is contained in the loess 5, even if the pulp 3 and the gypsum powder 4 are dried, there is no problem in uniform mixing.

The reason for containing water only in the ocher (5) is because it is more difficult to uniformly mix the pulp (3) having a viscosity and the gypsum powder (4) and the ocher (5) with each other. This is because it is easier to sprinkle and mix the expanded pearlite (2), the pulp (3), and the gypsum powder (4) on the ocher (5) containing a small amount of water and having viscosity. In addition, by using the moisture-containing ocher (5) as the adhesive (6, 6 '), to prevent the deterioration of the pulp and gypsum powder due to the moisture content to preserve the properties of the raw material as it is.

Of course, the foamed pearlite (2), pulp (3), gypsum powder (4), ocher (5) may be mixed with water, but it is preferable to contain water in the ocher (5).

Next, the mixture of the panel filler 1 containing water is compressed into a mold to form a panel, and then passed through a heater to evaporate the moisture contained in the mixture, thereby making the panel filler 1 in a hardened state. .

At this time, since the panel filler (1) consisting of the mixed pulp (3), gypsum powder (4), ocher (5) is compression molded in a state of entering the pores of the foamed pearlite (2) is dried and then foamed pearlite ( The pores of 2) and the adhesives 6 and 6 'bring about the effect of binding between the panel fillers 1, thereby further increasing the bonding force. In addition, even without a separate binder for the panel filler (1) it can be provided with a sufficient bonding force by the adhesion of the pores of the expanded pearlite (2) and ocher (5).

Due to this, the panel filler 1 is compressed and bonded with a great force, and the non-combustible panel has characteristics of the non-combustible panel, which is made of pulp, gypsum powder, and loess, which have an organic relationship with each other, and thus endure at high temperatures for a long time. As described above, the pulp 3 added to the panel filler 1 provides the tensile strength, the gypsum powder 4 provides the compressive strength, and the loess 5 provides the strong adhesive force, which is environmentally friendly. It is a non-flammable building panel filling material (1) having high strength.

Next, the non-combustible adhesives 6 and 6 'are applied to the outer surface of the panel filler 1, and the outer panels 7 and 7' are attached thereto. The outer panels 7 and 7 'may further increase the protection and strength of the panel filler 1.

Of course, as shown in Figure 1, the panel filler (1) by itself because it has sufficient strength, it turns out that it can be used as a non-combustible panel only by the pearlite panel filler (1) according to the purpose of use and the environment.

In addition, as shown in FIGS. 2 and 3, the outer panels 7 and 7 ′ may be used by compressing and attaching the outer panels 7 and 7 ′ to one or both sides of the panel filler 2.

In addition, although not shown in the drawings, the outer panels 7 and 7 'are disposed on one or both sides of the panel filler 1 by means of bolts, screws, rivets, etc. through the outside of the outer panels 7 and 7'. It can also be fastened.

The above uses the panel filler 1 itself as a non-combustible panel, attaches the outer panels 7 and 7 'by compressing it on one side or both sides, or by means of bolts, screws, rivets, or the like. A method of fastening the outer panels 7 and 7 'has been described, but the following description will explain the method of attaching the outer panels through the adhesives 6 and 6'.

The non-combustible adhesives 6 and 6 'applied before attaching the outer panels 7 and 7' are diluted with magnesium oxide (MgO), magnesium chloride (MgCl 2) and dibasic sodium phosphate (Na 2 HPO 4). It is prepared by mixing in a weight ratio of 4: 4: 2.

The magnesium oxide is produced in the form of a solid powder by heating metal magnesium in the air or pyrolyzing magnesium carbonate. In particular, it is generally used as a refractory material, crucible, magnesia cement, catalyst, and adsorbent. Magnesium and oxygen are used to absorb water and carbon dioxide from the air, and various uses such as refractory materials, catalysts, adsorbents and antacids. It is also used as an adhesive by mixing with magnesium oxide.

In addition, the magnesium chloride has a liquid form with a compound of chlorine and magnesium, has a strong hygroscopicity, and has a property of being well soluble in water and alcohol. It is used in many fields, such as tofu coagulants, wood preservatives, the production of parchment paper (sulfur), and the purification of wool.

In addition, the dibasic sodium phosphate is prepared by reacting the diluted phosphate solution with sodium carbonate, and depositing crystals at 35 ° C. or lower to form a powder. It is also colorless to white crystalline and has the property of being easily soluble in water and insoluble in alcohol.

In this case, when the magnesium oxide and magnesium chloride alone are mixed and used as the adhesives 6 and 6 ', the magnesium chloride is in a liquid phase, so that the particles protrude to the outside of the magnesium oxide, resulting in irregular and uneven coating surface. Therefore, the second sodium phosphate may be added to fill an irregular surface to form an even surface of the adhesive 6 and 6 '. In addition, the dibasic sodium phosphate is often heat-resistant enough to be used as a spray of the fire extinguisher, the magnesium oxide and magnesium chloride acts as a strong adhesive (6, 6 '), the dibasic sodium phosphate is a high temperature In this case, the adhesives 6 and 6 'are not melted at a temperature of 1000 ° C. in case of fire, thereby preventing the panel filler 1 and the outer panels 7 and 7' from being separated.

Therefore, the adhesive (6, 6 ') is easily melted during the fire, the panel filler (1) and the outer panel (7, 7') is separated to prevent the accident that collapses due to weakening of the building durability, flame-retardant material It can be used to prevent human injury from the generation of toxic gas.

As such, when the external panel 7 is attached only to one surface of the panel filler 1, the attached surface may be used as the outer or inner surface of the building, and the external panels 7 and 7 ′ may be formed on both sides of the panel filler 1. In the case of attaching), the application method can be implemented in various ways because both sides can be used as the exterior and the attachment surface of the building.

In addition, although the external panels 7 and 7 'are provided on only one surface, the external panels 7 and 7' can be provided on both sides to provide a higher strength non-flammable building panel. It can be produced selectively accordingly. In addition, it is preferable that the material of the outer panel is made of metal, but various other materials may be used.

In addition, although not shown in the drawings, the adhesive is applied to one or both surfaces of the panel filler 1, and then the external panel is attached thereto, and the external panel 7 is further fastened by means of bolts, screws, rivets, and the like described above. , 7 ') can further enhance the binding force.

As described above, the non-combustible building panel according to the present invention has the characteristics of the non-combustible building panel, which is made of pulp, gypsum powder and loess, which have an organic relationship with each other, so that they can stand at high temperatures for a long time. Of course, it is possible to manufacture a high-strength panel by improving the adhesive strength of the panel fillers, it is possible to prevent the emission of toxic gases in the fire because the fillers are environmentally friendly non-combustible materials. In addition, it is possible to prevent the degradation of the thermal insulation and sound insulation function due to deterioration of panel fillers, and to eliminate the disadvantages of pollution of the human body and the residential environment, as well as to prevent environmental pollution during disposal, The cost can be reduced, and the use of non-flammable adhesive prevents the external panel from separating from the panel filler at high temperature, which can slow down the collapse of the building as much as possible.
