1 to 4, an apparatus 100 for manufacturing an insulating plate according to an embodiment of the present invention includes a chamber 110 having an upper opening and including a storage space, a chamber 110 coupled with the chamber 110, And a pressure regulator 140 connected to the cover 120 to regulate the pressure of the storage space. The insulating plate manufacturing apparatus 100 may further include a gas supply unit 150 for supplying gas to the chamber 110.

The chamber 110 includes a storage space therein, and the filler material can be filled into the storage space through the open top with the top open. In one example, the chamber 110 may have a substantially hexahedral shape, but is not so limited, and the chamber 110 may have various shapes. 1 to 3 illustrate a state in which the upper surface of the chamber 100 having a hexahedral shape is fully opened, but the shape of the opened upper portion is not limited to the above, And size.

The filling material contains at least liquid sodium silicate as a raw material for manufacturing an insulating plate, and can be filled in the storage space with fluidity. As an example, the filler material may comprise mixed liquid sodium silicate and a polymeric material in a molten state. In addition, the chamber 110 may further include a heater for applying heat to the filler so that the filler filled in the storage space can maintain fluidity.

On the other hand, the insulating plate formed by the filling material may include hollow spherical ceramic silicones, and the ceramic silicon may be formed by reacting liquid sodium silicate and carbon dioxide gas contained in the filler.

The carbon dioxide gas may be supplied through a plurality of holes 132 formed in the bottom portion 130 of the chamber 110. Specifically, the plurality of holes 132 supply gas to the storage space, wherein the gas supplied in the plurality of holes 132 may include carbon dioxide gas. For example, the gas supplied from the plurality of holes 132 may include carbon dioxide gas and air or an inert gas. By controlling the mixing ratio between these gases, the flow rate of the supplied gas, etc., the size of the formed ceramic silicon, Density and so on. This will be described in detail with reference to FIG. 5 and FIG.

The chamber 110 may include therein a plurality of partitions 112 partitioning the storage space into a plurality of spaces. The plurality of partition walls 112 are spaced apart from each other by a predetermined distance, and may have a height smaller than that of the chamber 110.

The plurality of partitions 112 may be releasably coupled to the chamber 110. Therefore, maintenance of the plurality of partition walls 112 can be facilitated. For example, a guide groove or the like for coupling with the partition wall 112 may be formed on the inner wall of the chamber 110. The partition wall 112 may have a rail or the like coupled with the guide groove, (Not shown). However, the present invention is not limited thereto, and the plurality of partition walls 112 may be coupled with the inner wall of the chamber 110 by various methods.

A plurality of spaces separated by the plurality of partitions 112 may be filled with fillers, respectively, thereby forming a plurality of heat insulating plates at a time to improve the manufacturing efficiency of the heat insulating plates.

Meanwhile, the holes 132 may be formed at positions corresponding to the plurality of spaces in order to efficiently supply gas to the plurality of spaces separated by the plurality of partition walls 112. In one example, the bottom portion 130 of the chamber 110 may include a plurality of supply pipes 134 coupled with a plurality of holes 132 therein. That is, the plurality of supply pipes 134 and the plurality of partition walls 112 may be arranged alternately with each other.

The plurality of supply pipes 134 receive gas from the gas supply unit 150 and the distribution pipe 152 between the gas supply unit 150 and the plurality of supply pipes 134 supplies the gas supplied from the gas supply unit 150 And can be distributed to a plurality of supply pipes 134.

The bottom portion 130 may further include a plate film 136 covering the hole 132. The plate film 136 is rotatably engaged with one side edge of the hole 132 and has a size larger than the hole 132 to cover the hole 132. [ Therefore, it is possible to prevent the filling material filled in the storage space from flowing out through the holes 132. However, when the gas is supplied in the hole 132, the gas can be supplied to the storage space while the hole 132 is opened and the gas is lifted up the valve film 136.

The cover 120 may be coupled with the chamber 110 to seal the upper portion of the opened chamber 110. The cover 120 may be removably coupled to the chamber 110. The cover 110 and the cover 120 are separated from each other and the filler material fills the storage space of the chamber 110 and the cover 120 and the chamber 110 can be combined after the filler material is filled in the storage space . Since the plurality of barrier ribs 112 have a height smaller than that of the chamber 110, the plurality of barrier ribs 112 and the cover 120 may be spaced apart from each other. Therefore, an empty space may be formed between the plurality of partitions 112 and the cover 120.

A pressure regulator 140 is connected to the cover 120. The pressure regulator 140 may include a vacuum pump or the like and may control the pressure of the storage space. The suction pipe 142 connected to the pressure regulator 140 is coupled to the cover 120 through the cover 120 and the suction pipe 142 is connected to the plurality of partitions 112 and the cover 120, And can be connected to an empty space between them.

On the other hand, when the pressure in the storage space is lowered by the pressure regulator 140 in the state where the filling space is filled in the chamber 110, the gas contained in the filling material is discharged to the outside of the filling material, Lt; / RTI > When the gas is supplied by the holes 132 in this state, the gas can easily penetrate into the filler material.

5 and 6 are cross-sectional views schematically showing a method of manufacturing an insulating plate according to an embodiment of the present invention, FIG. 7 is a perspective view schematically showing an example of an insulating plate according to an embodiment of the present invention, and FIG. Is a cross-sectional view schematically showing an example of a cross section taken along the line III-III 'in FIG.

The method for manufacturing an insulating plate according to an embodiment of the present invention includes the steps of filling the storage space of the chamber 110 with the filler material 160 having fluidity, lowering the pressure of the storage space and supplying the gas to the filler material 160, And cooling the filler material 160 to form the heat insulating plate 170.

The filler material 160 may include mixed liquid sodium silicate and a polymer material in a molten state. The polymer material can be variously used as long as it solidifies upon cooling, and it is preferable that the polymer material has fire resistance and flame retardancy. Here, the cooling includes not only cooling the liquid filler 160 by a cooler, but also allowing the liquid filler 160 to stand at room temperature and solidify.

The liquid sodium silicate may be contained in the filler 160 in an amount of 30 wt% to 80 wt%.

If the content of the liquid sodium silicate is less than 30 wt%, too small spherical ceramic silicon 173 is formed in the matrix 172 of the heat insulating plate 170 and is hardly evenly distributed, Can be lowered. On the other hand, if the content of the liquid silicon silicate is larger than 80 wt%, the formation of the ceramic silicon 173 is concentrated at the lower portion of the filler 160 due to the carbon dioxide supplied from the bottom portion 130 of the chamber 110, The ceramic silicon atoms 173 are not evenly distributed in the matrix 172 and the liquid phase silicate which has not reacted with carbon dioxide remains in the matrix 172, so that the mechanical stability of the heat insulating plate 170 may be deteriorated. However, the liquid sodium silicate may be mixed at various ratios taking into consideration the porosity of the heat insulating plate 170, the heat insulating efficiency, the strength, and the like in a comprehensive manner.

The filler material 160 may further include at least one of a water repellent agent and a water repellent agent. The water repellent agent and the water repellent agent may be contained in the filler 160 in an amount of 0.5 wt% to 5 wt%, respectively.

The water repellent agent repels a wetting phenomenon on the surface of the hollow sphere-shaped ceramic silicon (173), thereby preventing the hollow sphere-shaped ceramic silicon (173) from being decomposed into liquid silicate and carbon dioxide gas reversibly reacting with moisture can do. The waterproofing agent is, for example, an inorganic permeable coating waterproofing agent, and may be composed of a mixture of a silicate-based and / or other organic and inorganic substances. The waterproofing agent can prevent dense sphere-shaped ceramic silicon 173 from being deformed by moisture or the like.

The chamber 110 may include a plurality of partitions 112 partitioning the storage space into a plurality of spaces. In the plurality of spaces separated by the plurality of partitions 112, Respectively. At this time, the filler material 160 may be filled up to a height lower than the height of the barrier ribs 112.

Further, the holes 132 for supplying the gas may be formed to correspond to a plurality of spaces defined by the plurality of partitions 112. At this time, the hole 132 is blocked by the plate film 136, so that the filling material 160 having fluidity can be prevented from flowing out through the hole 132.

After the filler material 160 is filled in the inner space of the chamber 110, the cover 120 may be coupled to the chamber 110 to seal the storage space.

Next, the pressure of the storage space is lowered by using a pressure control unit (140 of FIG. 1) connected to the suction pipe 142, and the gas is supplied to the filler material 160.

Specifically, since the plurality of partition walls 112 have a height smaller than that of the chamber 110, the pressure of the empty space between the plurality of partition walls 112 and the cover 120 is lowered, The bubbles B may be generated in the filling material 160 while the gas is discharged to the outside of the filling material 160 toward the empty space between the partition walls 112 and the cover 120. At this time, the lower the pressure of the storage space, the more easily the bubble B may occur in the filler material 160. The gas supplied from the lower portion of the filler material 160 by the holes 132 penetrates into the filler material 160 and moves to the upper portion of the filler material 160 in the form of a bubble B.

When the bubble B is generated in the filling material 160, the volume of the filling material 160 may increase, and the insulating plate 170 formed by the filling material 160 may be reduced in weight. At this time, since the filler material 160 is filled up to a height lower than the height of the barrier ribs 112, the filler material 160 can be prevented from overflowing even if the volume of the filler material 160 increases.

The valve film 136 that has closed the hole 132 is opened when the gas is supplied. For example, when the valve plate 136 is rotatably formed, the valve 132 can be opened while the valve plate 136 is lifted up by the pressure of the supplied gas.

The supplied gas includes carbon dioxide gas, and the carbon dioxide gas reacts with the liquid sodium silicate contained in the filler material 160 to form the ceramic silicon 173. [

Specifically, the filler material 160 may include a liquid sodium silicate region and a molten polymer material region, and the gas supplied to the filler material 160 forms a bubble B inside the filler material 160, When the bubbles B formed by the gas reach the liquid silicon silicate region, the carbon dioxide gas and the liquid sodium silicate react with each other as shown in the following reaction formula, so that the liquid silicon silicate forms the ceramic silicon 173.

[Reaction Scheme 1]

Na ₂ SiO _{3, 1} + CO _{2, g} SiO _{2, s} + Na ₂ CO _{3, g}

That is, the ceramic silicon 173 is formed so as to surround the bubble, and the ceramic silicon 173 may have a hollow sphere shape.

When the ceramic silicon 173 is formed as described above, the filler 160 is cooled to form the heat insulating plate 170. The heat insulating plate 170 may be formed according to the shape of the storage space in which the filler material 160 is filled. For example, FIG. 7 illustrates a heat insulating plate 170 having a plate shape, but the present invention is not limited thereto, and may be formed in various shapes.

The insulating plate 170 may include a matrix 172 formed by cooling a polymer material having fluidity and a ceramic silicon 173 dispersed in the matrix 172. As described above, the ceramic silicon 173 has a hollow sphere shape, and the inner space 175 is filled with a gas containing carbon dioxide gas, so that the ceramic silicon 173 can have an excellent heat insulating effect.

Meanwhile, the gas supplied from the plurality of holes 132 may include carbon dioxide gas and air or an inert gas, and the size and density of the ceramic silicon 173 dispersed in the matrix 172 may vary depending on the mixing ratio of these gases, The flow rate of the supplied gas, the pressure regulated by the pressure regulating portion (140 in FIG. 1), and the like.

The chamber 110 may further include a cooling unit for cooling the filler 160 to adjust the distribution of the ceramic silicon 173 by adjusting the cooling rate of the filler 160. As described above, since the ceramic silicon 173 has a hollow sphere shape, the ceramic silicon 173 can move to the upper portion of the filler material 160 within the filler material 160 having fluidity. Therefore, even though the carbon dioxide gas and the liquid silicon silicate initially concentrate the reaction at the lower part of the filler material 160, they can be moved to the upper part of the filler material 160 by the floating of the ceramic silicon 173 and can be uniformly distributed. However, when the cooling rate of the filler 160 is too low, the ceramic silicon 173 may be concentrated on the filler 160, so that the cooling rate of the filler 160 can be controlled by the cooling unit .

While the invention has been shown and described with reference to certain embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
