Description

Insulation Moisture Panel and its manufacturing method {PANNEL FOR HEAT SHIELD-DAMPPROOF AND METHOD THEREOF}

The present invention relates to a panel used for heat insulation and moisture proofing of a building, and more particularly, to a heat insulation moisture proof panel for attaching to an inner wall surface of a building such as an underground structure, a ground structure or a balcony, and to realize heat insulation and moisture proofing effect. It is related to a method.

In general, condensation occurs on the outer walls of buildings, on both sides of ground buildings, and on elevator walls of apartments, due to the temperature difference inside and outside. If not completely waterproofed or if gaps are formed, external water may penetrate into the building. Such condensation water or infiltration water moistens the interior of the building to cause an unpleasant odor due to mold, etc., and in severe cases, condensation water formed on the inner wall may flow into the interior of the building or the vehicle or flooring material present in the interior of the building. May adversely affect items such as furniture and furniture.

In order to solve the problems caused by the above condensation, etc., a conventional method of stacking moisture proof blocks was used, but the load of the building was increased, the internal space was reduced, and the transportation and construction was inconvenient. Patent No. 614457 has developed a heat-insulating and moisture-proof panel with a joint cut, combining a foamed resin molding, a synthetic resin coating layer, a non-combustible board, and the like.

However, the thermal insulation panel is used as a non-combustible board as a finishing layer, the thickness of the non-combustible board used at this time reached 3 ~ 6mm, because the moisture content of the non-combustible board itself reaches 25%, such as mold inside the non-combustible board This may occur, and when the panel is cut during construction, a large amount of dust is generated, which slows down the work speed and may adversely affect the health of the contractor.

In addition, an adhesive was used to attach the non-flammable board and the foamed resin molding, and when such an adhesive is unevenly distributed between the foamed resin molding and the non-flammable board, or the moisture content of the adhesive is changed, bending occurs in the panel. There was a problem that it is difficult to precise construction.

In addition, the thermal insulation panel was limited to determine the size because it was manufactured by adhering the non-combustible board and foamed resin molded product sold in a standardized size to a predetermined dimension, and was not produced in a batch and was manufactured separately because it had to go through the bonding process. There was a problem that the efficiency is low.

The present invention devised to solve the above problems, while minimizing the thickness of the surface except the heat insulation layer, and implements the maximum heat insulation and moisture-proof effect, high production efficiency, easy to install insulation moisture proof panel and its manufacturing method The purpose is to provide.

Heat-insulating moisture-proof panel according to an embodiment of the present invention for achieving the above object, the surface strengthening layer made of high impact polystyrene (HIPS: 0.18 ~ 0.24) on the upper surface of the heat insulating layer made of atmospheric pressure foamed polystyrene It is provided with a thickness of mm, the upper surface of the surface reinforcing layer is provided with a surface finishing layer made of a coating liquid mixed with a mortar having an antibacterial and fungal function and the adhesion enhancer in a ratio of 2: 3 to a thickness of 1.2 ~ 1.5mm It is characterized by the above-mentioned.

In addition, the lower surface of the heat insulating layer may be provided with a moisture-proof layer made of High Impact Polystyrene (HIPS).

In addition, the lower portion of the heat insulation layer and the moisture barrier layer may be provided so that a plurality of valleys in a straight line parallel to each other.

On the other hand, the method of manufacturing a heat-insulating moisture-proof panel according to an embodiment of the present invention for achieving the above object, continuous in the thickness of 0.18 ~ 0.24mm on the upper surface of the atmospheric pressure foam polystyrene sheet continuously molded to a thickness of 4.5 ~ 5.5mm A first step of heating and pressing the molded high impact polystyrene film to a temperature of 180 to 220 ° C .; A second step of contacting the atmospheric pressure foam polystyrene film with a thickness necessary for the lower surface of the atmospheric pressure foam polystyrene sheet and heat-compressing at a temperature of 180 to 220 ° C .; After the first step and the second step is finished, the coating liquid mixed with a mortar having an antimicrobial and mold resistance function and an adhesive strengthening agent in a ratio of 2: 3 is coated on the upper surface of the high impact polystyrene film in a thickness of 1.2 to 1.5 mm. A third step of doing; It is configured to include a.

In addition, in the second step, the pressure-forming polystyrene sheet continuously molded to a thickness of 5 to 8 mm is selected and added within the range of 1 to 15 sheets according to the required thickness, and heat-compressed at a temperature of 180 to 220 ° C. to increase the thickness of the thermal insulation layer. You can increase it as needed.

In addition, between the second step and the third step, the high impact polystyrene film continuously molded to a thickness of 0.18 ~ 0.24mm on the lower surface of the atmospheric pressure foam polystyrene sheet continuously molded to 4.5 ~ 5.5mm thickness of 180 ~ 220 ℃ The heat-pressing furnace may include an intermediate step of heat-pressing at a temperature of 180 to 220 ° C. on the lower surface of the atmospheric pressure foam polystyrene sheet, which has undergone the previous step, to improve the moisture-proof function of the heat-insulating and moisture-proof panel.

In addition, the intermediate step, immediately before the high-pressure polystyrene film continuously molded to a thickness of 0.18 ~ 0.24mm on the lower surface of the continuous pressure-forming foam polystyrene sheet continuously formed to 4.5 ~ 5.5mm thickness at a temperature of 180 ~ 220 ℃ The pressure-foaming polystyrene sheet and the high-impact polystyrene film are moved to contact the lower surface of the pressure-foamed polystyrene sheet and heated and pressed at a temperature of 180 to 220 ° C., and at the same time, a roller for forming a bone formed at regular intervals on the outer circumferential surface thereof. It is preferable to arrange in a direction perpendicular to the direction to form a valley on the lower surface of the heat-insulating and moisture-proof panel so as to quickly induce the movement of the condensation water formed on the surface.

Heat-insulating and moisture-proof panel according to an embodiment of the present invention configured as described above can be manufactured by changing the thickness of the heat-insulating layer made of atmospheric pressure foam polystyrene freely, without using a separate adhesive to configure the heat-insulating layer, surface reinforcement layer and moisture-proof layer. It is eco-friendly because it is constructed by heat compression method, and there is no banding phenomenon due to uneven distribution of adhesive or change of moisture content of adhesive, and since the panel itself is composed of self-extinguishing materials, it is possible to spread fire to the periphery when a fire occurs. It provides a useful effect of being prevented.

In addition, the heat-insulating and moisture-proof panel according to another embodiment of the present invention is provided with a surface hardening layer made of high impact polystyrene and a moisture-proof layer on both sides of the heat insulating layer, thereby achieving precise symmetry of both surfaces, such as when the tile is installed on the wall surface of a bathroom or the like. It provides a useful effect of attaching the finishing material more efficiently.

In addition, the heat-insulating and moisture-proof panel according to another embodiment of the present invention is provided with a plurality of valleys on the surface disposed toward the outer wall surface of the building, even if moisture is formed in the moisture-proof layer is quickly flowed downward along the valleys panel It provides a useful effect that moisture does not penetrate inside.

In addition, since the non-combustible board (NF board), which was widely used for surface finishing in the existing panel, is not used, the thickness of the panel for realizing a predetermined insulation and moisture proof effect is not only reduced, but also the weight of the panel itself. This reduces the load on the building. Furthermore, since the mortar with a smaller thermal insulation coefficient is used and the thickness is thinner than the non-combustible board, condensation does not occur on the surface reinforcement layer, and dust is not generated even when the panel is cut during the construction of the panel, thereby improving work efficiency. . In addition, the non-combustible board used in the past has a moisture content of about 25%, which may cause mold, etc., but in the present invention, by improving the above problems, since the mortar having a water resistance, antibacterial and mold resistance functions was used, The problem can be solved.

On the other hand, according to the manufacturing method of the heat-insulating and moisture-proof panel according to an embodiment of the present invention because the width is constant, but the length can be adjusted as desired, even if applied to various buildings with different heights to produce the panel to the desired height The versatility of the size adjustment provides a useful effect that can dramatically increase work efficiency in constructing panels.

In addition, the manufacturing method itself is through a batch production line, and as compared to the case of forming a moisture proof layer by attaching a non-flammable board to each of the ready-made foamed resin moldings as before, the manufacturing efficiency is dramatically improved and mass production is possible at low cost. Provide a useful effect.

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration, manufacturing process and construction process of the present invention.

1 is a cross-sectional view showing a configuration according to an embodiment of the present invention, illustrating a surface composed of a surface finishing layer 30, a surface hardening layer 20, a heat insulating layer 10, a moisture barrier layer (40).

Atmospheric pressure foam polystyrene constituting the insulating layer (10) is foamed at normal pressure, unlike ordinary styrofoam foamed under low atmospheric pressure conditions and can be implemented not only to realize a significant thermal insulation effect, even if the thickness is thin, 10mm or less Because of its flexibility, it does not break when bent or wound.

The top surface of the heat insulating layer 10 is provided with a surface reinforcing layer 20 to protect the heat insulating layer 10 from external impacts and serves to facilitate painting or attaching tiles to the panel surface, such a surface As the material constituting the reinforcing layer 20, it is preferable to use high impact polystyrene made by bonding rubber.

At this time, the surface reinforcement layer 20 should be able to implement the minimum surface strength to protect the heat insulating layer 10, when the thickness is more than a certain thickness, since the strengthening effect of the surface strength is low and occupies only more space, 0.18 ~ 0.24 Preferably, the thickness is mm.

On the other hand, the surface reinforcement layer 20 may provide a flat surface when painting or attaching the tile, but since the material of the surface reinforcement layer 20 itself is a synthetic resin, the surface may be easily peeled off and the tile may be attached. In this case, the adhesive strength is weak and the tiles can easily fall off. In order to compensate for this problem, in the present invention, the coating liquid 113 mixed with a mortar and an adhesive strengthening agent in a ratio of 2: 3 is coated on the upper surface of the surface reinforcing layer 20 to provide a surface finishing layer 30.

Recently, mortars with antimicrobial and mold resistance functions have been released by many companies. When the surface finish layer 30 is formed by mixing such a mortar with an adhesive strengthening agent, sufficient bonding strength is required even when painting or attaching tiles. Not only can have a mold on the surface does not cause an unpleasant odor or damage furniture placed around the wall. In this case, the thinner the surface finish layer 30, the better, but should be at least enough strength to be able to be firmly combined with the paint or tile panel is preferably composed of 1.2 ~ 1.5mm thickness.

As described above, the surface reinforcing layer 20 is provided on the top surface of the heat insulating layer 10, and the heat insulating moisture barrier panel having the surface finishing layer 30 on the top thereof is installed in a balcony or the like where condensation does not occur much. Could be.

On the other hand, in order for the heat-insulating and moisture-proof panel to be installed on the inner wall surface of the underground structure, etc., the moisture-proof layer 40 must be provided to prevent moisture from penetrating into the heat-insulating layer 10. At this time, the moisture barrier 40 is also preferably composed of high impact polystyrene excellent in light and moisture resistance.

As described above, the heat-insulating and moisture-proof panel provided with the moisture-proof layer 40 made of the same material as the surface reinforcing layer 20 on the lower surface of the heat-insulating layer 10 is precisely symmetrical on both sides, thereby minimizing the bending of the panel. Since it provides the best conditions for attaching tiles, it is suitable for construction in areas where tiles should be attached, such as bathrooms. Of course, if the construction inside the building, such as a toilet, the thickness of the insulating layer 10 will not have to be so thick.

In addition, when the heat-insulating and moisture-proof panel is to be installed on the inner wall surface of the underground structure, as illustrated in FIG. 1 (b), a straight valley 50 in the downward direction is formed on the lower portion and the moisture-proof layer 40 of the heat-insulating layer 10. It is preferable to be provided so that the condensation formed on the surface of the moisture-proof layer 40 can be quickly guided downward discharged. At this time, in Figure 1 (b) has been illustrated a shape in which the valleys 50 and the floor in a continuous shape, but the scope of the present invention is not limited to the shape shown in the drawings, other various modifications are possible. .

First, after contacting the high-impact polystyrene film 120 continuously formed to a thickness of 0.18 ~ 0.24mm to the upper surface of the atmospheric pressure foam polystyrene sheet 121 and heat-compressed to a temperature of 180 ~ 220 ℃ (first step-S10) . At this time, if the pressure is too thick atmospheric pressure polystyrene is added to the panel, there is a possibility that the panel bends, it is preferable to add a pressure foam polystyrene made of a thickness of about 4.5 ~ 5.5mm. On the other hand, the hot pressing process may be performed by introducing films into one or more thermal rollers (115, 116).

In general, the heat insulation moistureproof panel may vary in thickness of the heat insulation layer 10 according to the construction position. For example, a heat insulation moisture proof panel constructed in a region having a large temperature difference between the inside and the outside of the heat insulation moisture proof panel should have a thick thickness of the heat insulation layer 10, and on the contrary, a heat insulation moisture proof panel constructed in a region having a small temperature difference is a heat insulation layer (10). May be thin. Therefore, it is necessary to freely adjust the thickness of the heat insulating layer 10 as desired, so that this need can be met in the next step.

In this step, the atmospheric pressure foam polystyrene sheet 121 is contacted with the required thickness on the lower surface of the atmospheric pressure foam polystyrene sheet 121 which has been subjected to the above process, and heated and compressed to a temperature of 180 to 220 ° C. (second step-S20).

At this time, in order to adjust the thickness of the atmospheric pressure foam polystyrene sheet 121, rather than adjusting the thickness of each sheet, the continuous pressure-forming foam polystyrene sheet 121 continuously formed into a thickness of 5 ~ 8mm within the range of 1 to 15 sheets depending on the required thickness It is desirable to adjust the thickness by selecting and inputting in terms of mass production and manufacturing efficiency improvement.

Next, in order to form the surface finishing layer 30, the coating liquid 113 mixed with a mortar having an antimicrobial and mold resistance function and an adhesion strengthening agent at a ratio of 2: 3 on the upper surface of the high impact polystyrene film 120 is 1.2. It is coated to a thickness of ~ 1.5mm (step 3-S30).

On the other hand, in order to provide a moisture-proof layer 40 on the lower surface of the heat insulating layer 10, as illustrated in Figure 3, between the second step and the third step high impact polystyrene film 120 and atmospheric pressure foam polystyrene is compressed It is preferable to heat-compress the lower surface of the atmospheric pressure foam polystyrene sheet 121 which has been subjected to the second step.

At this time, the product passed through the second step and the intermediate step through the bone formation roller 117 to form a bone 50 in the lower portion and the moisture-proof layer 40 of the heat insulating layer 10 to be installed on the inner wall surface of the underground structure, etc. In this case, condensation can be discharged quickly.

Figure 5 illustrates the construction of a heat-insulating and moisture-proof panel according to an embodiment of the present invention, as shown in the drawing, the heat-insulating and moisture-proof panel according to the present invention can be freely determined the width of the vertical direction, the building to be constructed Construction can be made through the process of continuously combining only the left and right directions by manufacturing a heat-insulating and moisture-proof panel for the inner wall height of the. At this time, it is preferable to have a joint incision that is formed symmetrically in the shape of male and female at both ends to maximize the surface to be joined to the adjacent panel in order to make the coupling in the left and right direction more robust and to simplify the construction.
