Description

[0001] The present invention relates to a honeycomb board using a polyethylene glycol polymer resin,

The present invention relates to a honeycomb board having both incombustible, heat-insulating and sound-proofing properties, and more particularly, it relates to a honeycomb board having both opened ends of each cell of a honeycomb filled with a certain portion by foaming / curing reaction of a polyethylene glycol polymer resin and a silicon dioxide compound and water And the heat insulating material is formed in each honeycomb cell so as to have excellent nonflammability, heat insulating property and soundproofing property, and to make the board lightweight.

Generally, in many cases, a building is constructed by dividing an internal space into a certain space according to a necessary area after building a large internal space, and a partition member (various boards, partitions, etc.) ) Is often used. The partition member needs to be nonflammable in order to prevent the expansion of the fire or the combustion at an early stage in the event of a fire. Likewise, a fire door provided in an opening portion to prevent the spread of fire and combustion is also required to be nonflammable. In particular, according to the current Fire Service Act, indoor fire retardant standards are set high to protect the lives and property of the people from fire and disasters. The indoor fire prevention standards are set high in public offices, educational facilities, accommodation facilities, performance theaters, Since the finishing materials must be installed above the nonflammable and semi-nonflammable properties suitable for completing the firefighting, the selection of the nonflammable interior finishing materials is very important.

Generally, the heat insulating material is collectively referred to as a structure for preventing the heat flow, that is, the movement of the heat in the low direction from the high to the high, and the most frequently used heat insulating material is a building such as a house or a building. For example, when installing various buildings such as apartments or commercial buildings, it is common to obtain a thermal insulation effect by inserting an insulating board inside a wall, a ceiling surface and a floor surface. In the case of a building in which the insulation construction is completed in this way, since the internal heat is not easily taken out to the outside, the operation of the cooling apparatus in summer and the operation of the heating apparatus in winter can be greatly reduced, Can be reduced. In addition, insulation materials are widely used for mechanical or plant construction, heating or cooling of vehicles, ships, freezer warehouses, and household appliances. Insulating materials can be divided into inorganic materials and organic materials depending on the materials. Mineral wool, glass surface, ceramic fiber, and silica are used as high-temperature insulation materials. Insulating material is superior to inorganic materials, Materials include expanded polystyrene (styrofoam), expanded polyurethane (urethane), extruded expanded polystyrene (isoprene), and polyethylene (Atiron). As homes and buildings have become more sophisticated and more sophisticated, interest in insulation has been rising, and as insulation standards have been strengthened both domestically and overseas, insulation is expected to grow overall. In addition, due to the social environment in which the fire resistance of buildings due to various fire accidents is strongly demanded, it is expected that products with excellent fire-retardant performance will lead the insulation market.

In addition, "soundproofing" is also an important standard for construction. In general, soundproofing can be thought of as sound insulation and sound absorption. Sound insulation refers to blocking the noise from passing through the structure. For example, by installing two thin walls and creating an air layer between them, the sound can be raised. This is because the ability to transmit sound resonance in the order of solid, liquid, and gas is reduced. On the other hand, sound absorption is one of the factors of soundproofness judgment. Porous material (polyurethane, polyester, glass wool, ceramic sintered foam) has excellent sound absorption property with innumerable holes. Therefore, in the case of various boards used for construction, it is very important to provide sound insulation due to the characteristics of being partitioned between the respective spaces.

Prior art related to honeycomb board related to this is disclosed in Patent Publication No. 2009-0022753 (Mar. 04, 2009) (sound absorption and insulation reinforcing panel of honeycomb structure), which is a honeycomb structure used as a building interior and exterior material The present invention relates to a sound absorbing and adiabatic reinforcing panel, and more particularly, to a sound absorbing and adiabatic reinforcing panel comprising: a base panel; a reinforcing member disposed at one side of the base panel and having a predetermined height to form a predetermined space, And a perforated plate formed in the reinforcing member so as to allow the cell of the reinforcing member to communicate with the outside so as to correspond to the cell so that the external noise flows into each cell of the reinforcing member through the sound absorbing hole to be annihilated, Sound absorption and thermal insulation reinforcement of a honeycomb structure which not only has excellent effect but also has a simple structure and excellent physical characteristics against external impact or deformation Panel technology. However, the above-mentioned Patent Publication No. 2009-0022753 has a disadvantage in that it may have a sound-absorbing property according to a sound-absorbing ball, but the function is significantly deteriorated in terms of non-flammability and heat insulation.

Other objects, features and advantages of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Preferred embodiments of the honeycomb board using the polyethylene glycol according to the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It is provided to let you know. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

FIG. 1A is a view showing a honeycomb 10 of a general shape. The honeycomb (10) is a name attached to a hexagonal honeycomb structure, that is, a finite continuous structure of a hexagonal air column. When a honeycomb having such a structural characteristic is used as a sandwich board to be inserted and bonded between the surface materials, the structure and the bending strength are more durable than those of conventional boards. The material of the honeycomb is corrugated board material and metallic material, and it can be used variously such as a fire door, a general door, a partition, a furniture, and a car interior. As the surface material of the honeycomb, an iron plate, an aluminum plate, a plywood, a resin plate, a gypsum board and the like can be used. FIG. 1B is a top and bottom cross-sectional view showing clearly the space of each cell of the honeycomb. As shown in FIG. 1B, both ends of each honeycomb cell are open

FIG. 2A is a view showing an example in which the honeycomb 10 is applied inside the fire door, and FIG. 2B is a view showing that the honeycomb 10 is used in general furniture. Since the honeycomb is formed as a uniform space portion over the entire surface, a uniform compressive strength can be obtained at any position in all directions. In addition, the space portion of each honeycomb cell acts as a hexagonal column to prevent warpage and warpage of the surface material. However, such a honeycomb has a drawback that it is difficult to have a nonflammability. Of course, flame retardant honeycomb products that are treated with a special solvent having a nonflammable property such as flame retardant honeycomb are sold on the market, but the incombustibility is remarkably deteriorated.

3 is a top and bottom cross-sectional view of a honeycomb board 1 using a polyethylene glycol polymer resin according to an embodiment of the present invention. The space portion of each cell of the honeycomb 10 in the honeycomb 10 is sealed by both the first sealing portion 20a and the second sealing portion 20b filled in the space portion inwardly from both ends thereof, And the heat insulating material 30 is formed at the central portion.

Fig. 4 is a structural diagram showing the bonding relationship between the constitutions of the honeycomb board 1 using the polyethylene glycol polymer resin according to the embodiment of the present invention. First and second base sheets 40a and 40b are prepared so as to form the first and second sealing portions 20a and 20b at both ends of the honeycomb 10, respectively. As the first and second base sheets 40a and 40b, sheets of various materials may be used, and a polymeric plastic material or an acrylic material sheet may be used, or the sheet may be thick. It is preferable that the first and second base sheets 40a and 40b are formed by completely forming the first and second sealing portions 20a and 20b and then using the release member that can be peeled off from the honeycomb board 1, It is useful for processing. However, the first and second base sheets can be used together with the honeycomb board 1 even if they are not separated. In addition, plate-like members such as an iron plate, an aluminum plate, a plywood, a resin plate, and a gypsum board, which are used as surface materials of honeycomb in the construction field, may be used as the first and second base sheets 40a and 40b.

The polyethylene glycol polymer resin 50 is evenly coated on the first and second base sheets 40a and 40b thus prepared. Here, the polyethylene glycol polymer resin 50 is a main component constituting the first and second sealing portions 20a and 20b. Thereafter, the silicon dioxide compound and water (60) are sprayed onto the polyethylene glycol polymer resin (50) coated thereon. Here, the silicon dioxide compound and the water (60) allow the polyethylene glycol polymer resin (50) to foam and cure to an appropriate extent so that the space portion of each honeycomb cell can be filled from both ends thereof. The polyethylene glycol polymer resin 50 is applied and the first and second base sheets 40a and 40b on which the silicon dioxide compound and the water 60 are sprayed are adhered to both sides of the honeycomb 10 and attached thereto. In FIG. 3, both ends of the honeycomb are illustrated as honeycomb which is opened up and down, but it can be applied to any honeycomb having both open ends. For example, a honeycomb shape in which left and right ends are opened is also possible. On the other hand, although there is a press or the like as a pressurizing means for pressing both end portions of the honeycomb, any pressurizing means can be used, or it is also possible to manually press a worker using a heavy object. In this way, the pressure can be applied for a predetermined time by the pressurizing means, but it is preferable to pressurize for 20 to 40 minutes in consideration of the foaming / curing reaction time. The polyethylene glycol polymer resin 50, the silicon dioxide compound, and the water 60 contained on the first and second base sheets 40a and 40b attached to the honeycomb 10 when pressed by the pressurizing means, The cells are filled with foam, cured while filling the spaces of the cells from both ends to the inside of the space. The first and second sealing portions 20a and 20b filled with the foamed and cured foam fill the space portion of each cell of the honeycomb from the upper and lower ends to form the heat insulating weights 30 at the time of the filling.

In the honeycomb board 1 according to the present invention, the heat insulating weights 30 in each honeycomb cell are formed through the following steps.

Applying a polyethylene glycol polymer resin (50) onto the first and second base sheets (40a, 40b), respectively; Spraying a silicon dioxide compound and water onto the applied first and second base sheets (40a, 40b); The sprayed first and second basesheets 40a and 40b are pressed from both side ends of the honeycomb inward in the space portion of each cell of the honeycomb so that the first and second base sheets 40a and 40b The step of filling and attaching a predetermined portion of each cell of the honeycomb so that the polyethylene glycol polymer resin 50, the diacid, the silicon compound, and the water 60 cause the foaming and curing reaction, , And 2 sealing portions 20a and 20b can be formed. In addition, the first and second sealing portions 20a and 20b may be formed and then the first and second base sheets 40a and 40b may be peeled off.

The heat insulating sheath 30 formed as described above will contain carbon dioxide and methylene chloride gas. Carbon dioxide and methylene chloride gas are inert and very excellent gas insulation. Therefore, the adiabatic weighing chamber 30 is filled with carbon dioxide and methylene chloride gas in addition to air, thereby providing excellent incombustibility and heat insulation. The heat insulating weights 30 formed according to the present invention may occupy 30% to 90% of the volume of each cell space portion. Preferably, the size of the heat insulating weights 30 accounts for 60% to 90% of the space volume of each cell. 3 and 5 are views illustrating the sizes of the heat insulating weights 30 of the honeycomb board 1 formed according to the present invention.
