Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing an interior panel for a panel,

The present invention relates to a panel interior material used for a panel for a building, in which a hollow is formed therein, and a fire-extinguishing high-quality mineral is added to the casing to improve the fire resistance in the event of a fire and to reduce the weight of the building panel The present invention relates to a method for producing a panel interior material, and a method for manufacturing the same.

Generally, a building panel is used as an outer wall or an inner wall of a building, or as a material of a partition for an interior work, and can be used not only for the outer wall or the inner wall of a building but also for manufacturing a vehicle or an aircraft. So that the beauty of the exterior can be ensured to provide aesthetics, and interior accessories such as lighting fixtures can be easily fixed.

Such a building panel can be installed not only on a wall but also on a ceiling, and in particular, when installed on a ceiling, due to a load of a self-load and an installed interior object, a panel may be deformed over time, There has been a problem that when the humidity is high in the inside such as a temperature difference or a bathroom, corrosion occurs due to moisture.

To solve these problems, a panel made of a metal material is used as a building panel or a resin material panel made of a polymer resin is used to add a thermal insulation effect.

However, in the case of metal panels, there is an advantage that the panel itself is excellent in rigidity and durability, but the panel itself is excessively increased in load, which requires an operator skilled in installation work, and it is also difficult to install various interior accessories.

On the other hand, the resin panel has a merit that it is light and easy to install interior accessories, but has a problem that the strength of the panel itself is low and it is very vulnerable to fire such as the generation of poison gas due to the polymer resin material,

As mentioned above, besides metal or polymer resin, aluminum sheet or marble finishing material is also used as a building panel. However, there are problems such as oil pollution caused by deterioration of silicon caulking, internal condensation due to overheating of the finishing material, And corrosion of bricks, etc. Recently, in order to compensate for this problem, aluminum composite panels are used as building panels.

Generally, aluminum composite panels widely used are excellent in strength and durability of a panel itself by using a plate material such as an aluminum plate, and the occurrence of condensation is prevented by using polyethylene (PE) or polyurethane heat insulation material as a core material between the plate materials The heat insulating performance can be secured.

Open Publication No. 2015-0040675 (Apr. 15, 2015) discloses an aluminum plate having an inner space formed therein, a heat insulating material, an air layer forming plate having an air layer formed therein and holding air therein, A composite panel is presented.

However, in the case of the above-described conventional technology, the aluminum plate is still used as a thermal insulation material with a foamy quality insulator. In addition, when the fire is generated, it is not only well burned but also burns and generates toxic gas.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As well as the fact that

Throughout this specification, when an element is referred to as "including" an element, it is understood that it may include other elements as well, without departing from the other elements unless specifically stated otherwise.

Hereinafter, a manufacturing method of a panel interior material according to the present invention and a manufacturing method of a building panel including the panel interior material will be described in detail.

First, referring to FIG. 1, a method for manufacturing a panel interior material according to the present invention comprises the steps of: preparing a core 10 containing a polymer resin; Applying a solvent to a surface of the core; A coating step of coating the mineral powder on the surface of the solvent-applied core to form a sheath 50; And a heat treatment step of heating the core formed with the outer shell to produce a hollow body 100 having a hollow 101 formed therein.

The panel interior material may be a hollow body 100 having a hollow 101 formed therein and the surface of the hollow body may be formed of a heat treated shell 105. The heat treated shell 105 may be made of a mineral powder And a molten polymer resin.

More specifically, the core 10 may be manufactured by molding a thermoplastic resin, which is melted when exposed to a high temperature, to a predetermined shape. The thermoplastic resin may include a resin such as a poly styrene resin, a poly ethylene resin, a nylon resin, a polyacetal resin, a poly vinyl chloride resin, an acrylonitrile resin butadiene styrene copolymer, a polyacryl resin, and a polypropylene resin. The shape of the core is not particularly limited, but it is preferably spherical And the core 10 can be manufactured by molding.

In addition, it is preferable that the longest inner line segment of the molded core 10 is 1 to 5 mm. If the size of the longest horizontal cross section is out of the range, if the size of the panel interior material is too small, It is difficult to obtain a weight reduction effect as much as desired due to the size of the hollow interior of the interior material being too small. When the size is too large, it is difficult to form a uniform thickness at the time of forming the outer cover, There is a problem that the shape of the hollow formed inside the panel interior material becomes irregular.

In this case, the longest inner line segment of the core means the longest line segment among the line segments between arbitrary points on the outermost surface of the core formed in a three-dimensional shape and another arbitrary point. For example, The diameter of the sphere may be the longest inner segment.

For example, in the step of manufacturing the core 10, a cored polystyrene core can be produced by foaming a small polystyrene granule through a polystyrene resin bead foaming method. For example, A polystyrene core having a spherical shape of 2 to 3 mm can be produced.

A coating step of applying a solvent to the surface of the core is carried out in order to adhere and adhere the outer skin to the core, wherein the solvent serves to adhere the mineral powder constituting the outer shell and the core to each other.

The solvent to be used in the application step may be a generally used hydrophilic solvent, preferably water which can be easily obtained.

As an example, it is preferable that the application step is such that water is sprayed by spraying water to such an extent that the surface of the produced core can be fully written.

The coating step of coating the mineral powder on the surface of the core coated with the solvent through the coating step to form the covering 50 is preferably carried out by rotating the core coated with the solvent into the rotating body and rotating the core. And spraying a mineral powder having a size of 100 to 500 Mesh onto the surface of the core to be rotated to form the shell 50 with a thickness of 0.1 to 3 mm.

In detail, to form a shell 50 having a uniform thickness on a core coated with a solvent, the core coated with the solvent is put into a rotating body, rotated while spraying a mineral powder having a size of 100 to 500 mesh, mm in thickness, wherein the mineral powder forming the shell is selected from the group consisting of clay powder, silica powder, quartz powder, tourmaline powder, pegmatite powder, column bite powder, calcite powder, biotite powder, elvan powder and apatite powder And the like.

Hwangto (red clay) is one of the eco-friendly building materials with a high preference, usually means pressed and dingy soil, Huangyang. These loess are composed of pale yellow fine sand and clay silt-sized particles carried by the wind and deposited. Natural loess is loosely transformed by potassium carbonate and is usually homogeneous, unfamiliar and has a high porosity. It also accounts for about 10% of the total surface soil, and about 35% of the soil in the Republic of Korea is made of loess and is easily available anywhere. This loess has excellent effect in eliminating the bad energy that invades from the outside because it is excellent in weakness and toxicity. It radiates far infrared ray which is beneficial to human body, increases blood flow, promotes metabolism, relieves fatigue and increases immunity . In addition, the hydrangea contained in the hydrangea, the enzyme has the effect of preventing the aging phenomenon. In addition, loess has a great effect in controlling indoor humidity because it absorbs moisture when humidity is high and moisture is released into the air when the room is dry.

In case of quartz powder, quartz powder, tourmaline powder, pegmatite powder, column bite powder, calcite powder, biotite powder, crushed stone powder and apatite powder, far infrared rays and anion are radiated to activate the cells of the body to recover the fatigue It relieves the stress, has the function of removing the toxins, fungi and various bacteria, and has not only excellent deodorization function, but also has the porosity, and has the function of controlling the humidity by the warming function, the sound absorption function, the absorption of harmful substances, and the moisture absorption desorption.

Accordingly, in the case of the panel interior material of the present invention, when the building panel filled with the panel interior material is used due to the mineral material formed on the outer skin 50, it is possible to prevent the sick house syndrome by absorbing chemicals harmful to various human bodies Far infrared ray emission, antibacterial function, deodorization function, humidity control function can be expected.

For example, in the coating step, a core coated with a solvent is inserted into a rotatable disk having a concavo-convex bottom, and a mineral powder, preferably a loess powder, is sprayed while the core coated with the solvent is rotated, It is possible to coat the mineral powder with one thickness to form the shell. In this case, the particle size of the mineral powder is preferably 100 to 500 Mesh. When the particle size is smaller than the above range, the number of pores is too large, so that the strength of the shell is not sufficient and the hollow body may be broken. The pore size formed in one of the mineral powder grains is not sufficient, so that the specific functionality possessed by the mineral powder such as the decrease of far-infrared ray emission may be lowered.

The thickness of the outer cover 50 formed in the coating step is preferably 0.1 to 3 mm. If the thickness is less than 0.1 mm, the thickness of the outer cover is insufficient and the hollow body is broken or crumbled. In addition, when the thickness of the shell exceeds 3 mm, the hollow volume inside the hollow body may be reduced and the weight reducing effect of the panel interior material may be deteriorated.

The core having the outer shell formed through the coating step is melted and penetrated into the outer shell through the heat treatment step so that the mineral powder is bonded to each other with the molten polymer resin to form a hard heat treated shell 105, The hollow body 100 having the hollow 101 therein can be manufactured.

Preferably, the cores having the shells formed therein further include a cleaning step to prevent the mineral powders from binding to each other before the heat treatment step to detach the mineral powder from the surface of the core during the heat treatment step, and to form a uniform surface of the shell . In addition, contaminants or impurities formed on the outer skin may be removed in the coating step.

The cleaning step may generally clean the cores on which the shell is formed through a dry cleaning method of spraying sublimation particles.

For example, the cleaning step may be dry-cleaned by using a single gas or two or more mixed gases selected from the group consisting of HF, CF ₄ , CO ₂ , NH _3, and Ar, The flow rate of the gas can be appropriately adjusted depending on the type of the gas. For example, while injecting gas at a flow rate ranging from 1 to 500 sccm for HF gas, 1 to 500 sccm for NH ₃ gas, 1 to 500 sccm for CF ₄ , and 1 to 600 sccm for Ar gas, a pressure of 3 mTorr to 300 mTorr The core formed with the shell may be dry-cleaned.

Specifically, in the heat treatment step, the core 10 having the outer shell is heated to a temperature of 600 to 800 ° C. to remove the core 10 containing the polymer resin, thereby producing the hollow body 100 having the hollow 101 formed therein. If the temperature is out of the range, the core may not be sufficiently melted and the hollow shape may be irregular or voids may not be formed in the inside, and the adhesion between the mineral powders constituting the shell may be lowered to lower the strength of the hollow body If the heat treatment is performed in excess of the temperature range, a problem may arise that the polymer resin is eluted to the outer surface of the envelope and the shape of the outer envelope is deformed.

Meanwhile, in the case of the hollow body 100 manufactured through the heat treatment step, a biodegradable polymer may be coated to improve the strength of the hollow body and to form a uniform surface to improve the sense of beauty. The protective film is preferably formed to a thickness of 0.01 to 0.35 mm on the outer surface of the shell. When the thickness of the protective film is out of the above range, the thickness of the protective film is thick, so that the functional effect peculiar to the mineral powder such as the far-infrared radiation effect of the mineral powder contained in the shell is reduced If the thickness of the protective film is less than 0.01 mm, there is a problem that it can not act as a protective film at all.

As described above, in the case of the panel interior material of the present invention, the interior of the panel made of a polymer resin is heat treated to form a shell containing a mineral substance, thereby melting and removing the polymer resin. It is possible to remarkably reduce the weight as compared with beads made only of mineral materials having the same particle size, thereby improving the workability at the time of building construction and also expecting the effect of heat insulation or sound insulation due to the hollow formed inside.

According to another embodiment of the present invention, there is provided a method of manufacturing a building panel including a panel interior material, comprising: preparing an exterior panel 200 having a predetermined size and thickness; And filling the panel interior material produced by the above-described manufacturing method while spraying the adhesive between the prepared exterior panel.

The adhesive used in the filling step is not particularly limited as long as it is an adhesive material. However, it is preferable to use a polymeric ceramic bond in order to improve the adhesion between the panel interior materials.

For example, as shown in FIG. 2, two outer plates or veneers 200 having a predetermined size and thickness are prepared, and the adhesive is sprayed between the prepared outer plate and the veneer plate, And the interior of the hollow chain panel is filled with the hollow interior of which only the shell portion is left, so that the construction panel including the panel interior material of the present invention can be manufactured. The manufactured building panel may be provided with an interior effect by exposing the surface filled with the panel interior material to the outside. For example, when yellow soil is used as a mineral powder, the interior material for the panel having the outer covering including the loess, that is, the loess bead is filled between the outer plates, and then the loess bead is continuously disposed outside the exposed surface. The interior effect can be obtained.

As another example, as shown in FIG. 3, the panel interior material 100 of the present invention is filled in place of the existing foam in the prefabricated decorative panel 210 to improve the fireproof performance in case of fire, thereby completing the disadvantages of the prefabricated panel which is vulnerable to fire . Specifically, the panel interior material 100 is filled in the interior of the prefabricated decorative panel 210 having an artistic image and an art, and then the panel interior material 100 is bolted to the wall through the holes 215 It is also possible to arrange different makeup panels continuously in the left, right, upper, lower and diagonal directions of the fixed facial panel, thereby improving the interior effect and compensating for the weakness of the fire and reducing the weight of the panel due to the hollow formed in the panel interior material It is possible to provide a construction panel having improved workability.

The present invention is not limited to the above-described specific embodiments and descriptions, and various modifications can be made to those skilled in the art without departing from the gist of the present invention claimed in the claims. And such modifications are within the scope of protection of the present invention.
