Organics and inorganics show clear differences in their properties. In the case of insulation material, organic insulation material has excellent thermal insulation performance, economical and constructability advantages, but it has fatal disadvantages such as fire vulnerability and harmfulness during combustion. On the other hand, inorganic insulation materials have disadvantages such as insulation performance that is much lower than organic insulation materials, such as concern about the harmful effects of dust such as glass wool and mineral wool, difficulty in producing various forms, and poor performance due to high absorption rate. Compared with the organic insulating material, there is an excellent advantage. Recently, as safety is considered important, interest in inorganic insulation materials is increasing, and research on organic-inorganic fusion materials is also being conducted.

The present invention relates to a vacuum impregnation device for manufacturing an organic-inorganic fusion insulation and a method for producing an organic-inorganic fusion insulation using preferably, it will be described below.

1. Vacuum impregnation device

1 to 3 are embodiments of the vacuum impregnation apparatus according to the present invention, respectively, a front perspective view, a rear perspective view, and a sectional view. The vacuum impregnation device according to the present invention comprises two vacuum impregnation chambers 100 and 200 and two vacuum impregnation chambers 100 and 200 communicating with each other to reduce the vacuum to make a vacuum state. There is this. To this end, the vacuum impregnation device according to the present invention comprises essentially the first impregnation chamber 100, the second impregnation chamber 200, the first communication tube 510, the vacuum pump 300, further backflow prevention chamber 400, the second and third communication pipes 520, 530, and 540 may be further included.

The first and second impregnation chambers 100 and 200 are provided with the container bodies 110 and 210 and the sealing lids 120 and 220, thereby opening the sealing lids 120 and 220 in the container bodies 110 and 210. Insertion and closing the sealing lid (120, 220) can seal the inside of the container body (110, 210). One of the first and second impregnation chambers 100 and 200 is filled with an impregnation liquid (LM, an inorganic impregnation liquid), and an impregnation substrate (SM, an organic porous substrate) is inserted into the other side. In particular, in the present invention, the first and second impregnation chambers 100 and 200 may be used while alternately filling the impregnation liquid LM and the impregnation substrate SM (the first and second impregnation chambers are alternately impregnated tanks). It is desirable to provide the same shape and structure. The container bodies 110 and 210 of the first and second impregnation chambers are conventional insulation panels to be inserted in consideration of the fact that the organic porous substrate, which is the impregnating substrate SM inserted therein, is a foam type insulation panel. It is preferable to provide a rectangular metal container of a size that can be used. However, since the rectangular metal container may be deformed during the decompression process, it is preferable to appropriately reinforce it with the reinforcing materials 111 and 121. 3 to 5 show the first and second impregnation chambers 100 and 200 of a size which can be inserted by standing up the insulation panel having a size of 300 * 500 * 50.

The first and second impregnation chambers 100 and 200 may be provided in a sealed structure of the container bodies 110 and 210 and the sealed lids 120 and 220. In this case, the sealed structures may include the packing 222 and the lock valve 121. 221). The first and second impregnation chambers 100 and 200 may be provided with pressure gauges 130 and 230 to the inspection windows 10 and 240, and the first and second impregnation chambers may be provided through the pressure gauges 130 and 230. The internal pressure of the 100 and 200 may be checked and the internal state of the first and second impregnation chambers 100 and 200 may be checked through the check windows 140 and 240. In addition, the first and second impregnation chambers 100 and 200 have outlets formed at the bottoms of the container bodies 110 and 210, and are connected to the discharge pipes 150 and 250, and open / close valves such as drain valves 151, 251 may be mounted, whereby the residue of the remaining impregnation liquid LM remaining in the first and second impregnation chambers 100 and 200 may be easily discharged, and the first and second impregnation chambers 100 and 200 may be easily discharged. ) You can clean the inside.

The vessel body (110, 210) of the first and second impregnation chamber may be installed to prevent the lifting frame (160, 260) and / or sieve (170, 270) removable, the injury prevention frame (160, 260) and / Alternatively, the sieves 170 and 270 may be detachably installed only in the impregnation chamber into which the impregnation base SM is inserted when the vacuum impregnation apparatus is used. At this time, the injury prevention frame (160, 260) is installed on the upper container body (110, 210), the strainer (170, 270) is installed close to the bottom of the container body (110, 210). Flotation prevention frame (160, 260) is a configuration for suppressing the injury of the impregnation base (SM) during the impregnation process, it is appropriate to provide a metal frame of the grid structure. The filtering nets 170 and 270 are configured to filter out the mass from the impregnation liquid LM and impregnate the impregnating substrate SM evenly without agglomeration. Injury prevention frame (160, 260) and the strainer (170, 270) is simply hanging on the engaging jaw (112, 113, 212, 213) formed on the inner surface of the container body (110, 210) of the first and second impregnation chamber Can be installed.

The first and second impregnation chambers 100 and 200 are connected between the container bodies 110 and 210 at the bottom by the first communication tube 510. The first communication tube 510 is provided with an on / off valve 511 to open and close a valve. According to the opening of the 511, the container body (110, 210) is in communication. Therefore, when the on-off valve 511 is opened, the impregnation liquid LM filled in one of the first and second impregnation chambers 100 and 200 can move to the other side through the first communication pipe 510.

The vacuum pump 300 is for reducing the pressure in the first and second impregnation chambers 100 and 200 with a vacuum. When the vacuum impregnation apparatus is used, the impregnation substrate SM of the first and second impregnation chambers 100 and 200 is used. The pressure is reduced only on the side where is inserted. As a result, a pressure difference is generated between the first and second impregnation chambers 100 and 200, and the impregnating liquid LM is moved to the side through which the impregnation base SM is inserted through the first communication pipe 510 by the pressure difference. While impregnating the impregnation base (SM).

The backflow prevention chamber 400 and the second and third communication pipes 520, 530, and 540 become additional components for preventing the backflow of the impregnation liquid LM during the impregnation process. For example, when the impregnation base material SM is inserted into the first impregnation chamber 100 and the impregnation liquid LM is filled in the second impregnation chamber 200, the first impregnation chamber 100 is decompressed to open / close the valve of the first communication pipe. When the opening 511 is opened, the impregnation liquid LM of the second impregnation chamber is impregnated with the impregnation substrate SM while moving to the first impregnation chamber 100 through the first communication pipe 510. The impregnation may not be performed smoothly due to backflow due to the pressure rise in the first impregnation chamber 100. In this case, it is necessary to continuously operate the vacuum pump 300 in order to prevent the back flow, but in the process, the impregnation liquid (LM) may be introduced into the vacuum pump 300 may damage the vacuum pump 300, preventing the back flow The chamber 400 serves to block inflow into the vacuum pump 300 by receiving the impregnation liquid LM in the middle. In particular, when the inorganic impregnation liquid (LM) using the gypsum-based binder as the impregnation liquid (LM), the impregnation liquid (LM) moved to the first impregnation chamber (100) having the impregnation substrate (SM) during the impregnation process bubbles It can be overflowed while generating, the backflow prevention chamber 400 receives the overflowing bubbles so that the impregnation is effectively made. In addition, in the present invention, since the first and second impregnation chambers 100 and 200 are alternately impregnated with each other, the vacuum pump 300 is connected to each of the first and second impregnation chambers 100 and 200 so that the first and second impregnation chambers ( 100, 200 are alternately reduced in pressure, but the backflow prevention chamber 400 may be configured to effectively reduce the pressure of the first and second impregnation chambers 100 and 200 alternately with one vacuum pump 300.

The backflow prevention chamber 400 may be provided as a sealed space of a sealed structure by the container body 410 and the sealing lid 420 similarly to the first and second impregnation chambers 100 and 200, and the inspection window 440. Along with the outlet, the discharge pipe 450, the opening and closing valve 451, may be provided to be provided. The second communication pipes 520 and 530 connect the first and second impregnation chambers 100 and 200 and the backflow prevention chamber 400 on the first communication pipe 510, and are provided with opening and closing valves 521 and 531 to open and close the second communication pipes 520 and 530. As the valves 521 and 531 are opened, the first and second impregnation chambers 100 and 200 communicate with the non-return chamber 400. The third communication pipe 540 is connected while communicating between the backflow prevention chamber 400 and the vacuum pump 300. In such a structure, when the vacuum pump 300 is operated while the opening / closing valves 521 and 531 of the second communication tube are properly opened or closed, either one of the first and second impregnation chambers 100 and 200 is reduced in pressure. For example, if the first impregnation chamber 100 is to be depressurized, the opening / closing valve 521 of the second communication pipe between the first impregnation chamber 100 and the non-return chamber 400 is opened and the flow back to the second impregnation chamber 200. The opening and closing valve 531 of the second communication pipe between the prevention chamber 400 operates the vacuum pump 300 in the closed state (see FIG. 6 (b)), and opens and closes the pressure if the second impregnation chamber 200 is to be decompressed. The vacuum pump 300 is operated with the valves 521 and 531 reversely opened and closed.

2. Manufacturing method of organic-inorganic fusion insulation

6A to 6C are cross-sectional views of a manufacturing process of the organic-inorganic fusion thermal insulation using the vacuum impregnation device of FIGS. 3 to 5, and looks at the manufacturing method of the organic-inorganic fusion thermal insulation.

First, the organic porous substrate SM is put in the first impregnation chamber 100 and the inorganic impregnation liquid LM is put in the second impregnation chamber 200 to seal the first and second impregnation chambers 100 and 200, and then vacuum. The pump 300 is operated to depressurize the first impregnation chamber 100 (first step). If the upper anti-floating frame 160 and the lower strain screen 170 is further installed in the container body 110 of the first impregnation chamber, the organic porous substrate SM is the anti-floating frame of the first impregnation chamber 100 ( Inserted between 160 and the strainer 170.

In the organic-inorganic fusion insulation material, the organic porous substrate (SM) has open pores and form resilience. For the impregnation of the inorganic impregnation liquid (LM), the organic substrate must have open pores (open cell structure) and impregnated (or compressed). Afterwards, a resilience is needed to restore the existing shape. Thus, as shown in FIG. 2, the inorganic impregnation liquid LM is fused to the organic porous substrate in a coating or film form. Polyurethane foam may be preferably used as the organic porous substrate (SM), and the polyurethane foam is an economical material having open pores made of organic materials satisfying characteristics such as shape control, pore control, shape restoring ability, and ease of impregnation. to be. The inorganic impregnation liquid (LM) is impregnated with the organic porous substrate (SM) and then forms a coating or film to impart flame retardancy to the surface and the inside of the organic porous substrate (SM) and at the same time improve the thermal insulation performance by making a part of the open pores closed pores. It plays a role. The inorganic impregnation liquid (LM) is a gypsum binder, a curing retardant, a fluidizing agent, a polymer. As a composition including water, a composition having a coma amount of 40 to 100% by weight compared to a gypsum-based binder is preferable.

Next, when the inside of the first impregnation chamber 100 is depressurized, the opening / closing valve 511 of the first communication tube is opened to move the inorganic impregnation liquid LM in the second impregnation chamber 200 to the first impregnation chamber 100. While impregnating the organic porous substrate (SM) (second step). According to the pressure difference between the first and second impregnation chambers 100 and 200, the inorganic impregnation liquid LM in the second impregnation chamber 200 having a high pressure is lowered through the first communication pipe 510. While moving to 100, the interior of the first impregnation chamber 100 is filled, thereby impregnation of the organic porous substrate SM in the first impregnation chamber 100. At this time, since the inorganic impregnation liquid LM is gradually filled from the bottom of the first impregnation chamber 100, the inorganic impregnation liquid LM is impregnated while being sucked from the lower portion of the organic porous substrate SM, and thus the inorganic impregnation liquid LM is organic-based. It is impregnated while effectively penetrating into the porous substrate SM. On the other hand, if the upper anti-wound frame 160 and the lower strainer 170 is further installed in the container body 110 of the first impregnation chamber, the inorganic impregnation liquid (LM) is a lump is filtered by the strainer (170, 270) The organic porous substrate SM is impregnated and impregnated while the floating prevention frame 160 suppresses the floating of the organic porous substrate SM by buoyancy.

Subsequently, after the impregnation process, the organic porous substrate SM impregnated with the inorganic impregnation liquid LM is removed from the first impregnation chamber 100 and dehydrated and dried (third step). The dehydration process is carried out by roller compaction, and the drying process is preferably performed at 70 ° C. for at least 3 hours. As a result, the inorganic-based impregnation liquid LM penetrates and is coated on the organic porous substrate SM, thereby completing an integrated organic-inorganic fusion insulating material.

Meanwhile, after removing the organic porous substrate SM impregnated from the first impregnation chamber 100, the waste liquid of the inorganic impregnation liquid LM remains in the first impregnation chamber 100, and the inside of the second impregnation chamber is empty. do. Impregnating with the remaining waste liquid in the first impregnation chamber 100 may again produce an organic-inorganic fusion insulator. In this case, the organic porous substrate SM is placed in the empty second impregnation chamber 200. After the first and second impregnation chambers 100 and 200 are sealed, the vacuum pump 300 is operated to depressurize the second impregnation chamber 200 (fourth step), and when the inside of the second impregnation chamber 200 is depressurized. Opening the opening and closing valve of the first communication tube to impregnate the organic porous substrate (SM) while the inorganic impregnation liquid (LM) in the first impregnation chamber (100) is moved to the second impregnation chamber (200) and then the second impregnation chamber The organic porous substrate SM impregnated with the inorganic impregnation solution at 200 may be taken out, dehydrated, and dried (step 5). As a result, the inorganic impregnation liquid LM can be carried out in a continuous impregnation process while the first and second impregnation chambers 100 and 200 alternately come and go.

The present invention has been described in detail above with reference to specific embodiments, but the embodiments are only for illustrating the present invention, and thus the embodiments substituted, added, and modified within the scope without departing from the spirit of the present invention are also described below.
