Description

Insulating material and method for manufacturing the same

[0001] The present invention relates to an aerogel insulation material and a technique for manufacturing the same.

[0002] The technology underlying the present invention relates to aerogel insulation.

[0003] In the case of home appliances that require insulation, such as refrigerators, insulation materials and other insulation means are installed in specific locations or structures, but due to the nature of the insulation materials, their thick thickness makes their application limited.

[0004] As an example related to this, Korean Patent Publication No. 10-2017-0092039, a prior art document on a refrigerator, discloses a pillar that is attached to the door of the refrigerator and rotates according to the opening and closing of the door to block the storage compartment from the outside.

[0005] However, since such a pillar is formed with a thin thickness, it was difficult to embed insulation manufactured with a thickness greater than that of a thin pillar inside the pillar.

[0006] In addition, the inside of the pillar is formed into a specific structure, and when the insulation is manufactured in a thin thickness, the strength decreases, making it difficult to process the insulation for interior use according to the specific structure.

[0007] Due to these limitations, the insulation effect through the pillars was inevitably limited as they were used without any insulation material built into the pillars in the past.

[0008] The present invention aims to improve the limitations of the prior art as described above.

[0009] Accordingly, the present specification seeks to provide an embodiment in which the thickness can be formed into a thin shape.

[0010] In addition, it is intended to provide an embodiment that can maintain insulation performance while forming a thin thickness.

[0011] In addition, it is intended to provide an embodiment in which the external shape of the insulation material can be processed flexibly and easily.

[0012] In addition, we aim to provide an example that can improve the energy consumption efficiency of the applied product.

[0013] The present invention, which aims to solve the above-described problem, uses a means of composing the content of each of a plurality of components according to the desired thickness.

[0056] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings.

[0058] <Method of manufacturing insulation material>

[0059] An embodiment of a method for manufacturing an insulating material is a method for manufacturing an insulating material (1) as shown in FIG. 1 to a specific thickness (D) or less.

[0060] Here, the specific thickness (D) may be 500 [um].

[0061] That is, the above method for manufacturing an insulating material may be a method for manufacturing an insulating material with a thin thickness of 500 [um] or less.

[0062] The above insulation material (1) can be manufactured in a bar shape having a certain thickness (D) as shown in Fig. 1.

[0063] The above insulation material (1) may be an aerogel insulation material composed of fiber material, organic material, and precursor, and having a structure in which an aerosol (3) is distributed in fiber (2) as shown in FIG. 2.

[0064] The above insulating material (1) is made of a material structure as shown in Fig. 2, and the outer surface can be coated with a coating material (4) as shown in Fig. 1.

[0065] An embodiment of the method for manufacturing the above-mentioned insulating material (1) to manufacture the above-mentioned insulating material (1) with a thin thickness of 500 [um] or less manufactures the above-mentioned insulating material (1) by composing the content of each of a plurality of components according to the thickness to be formed.

[0066] The method for manufacturing the above insulation material includes, as shown in FIG. 3, a step (S1) of forming a substrate by introducing a fiber material having a weight within a first range, which is a weight range at a certain ratio relative to the thickness, and an organic material having a weight within a second range, which is a weight range at a certain ratio relative to the weight of the insulation material (1), a step (S2) of impregnating the substrate with a precursor having a weight within a third range, which is a weight range at a certain ratio relative to the weight of the insulation material (1) minus the weight of the organic material, and a step (S3) of drying an impregnation product in which the substrate is impregnated with the precursor.

[0067] In the above method for manufacturing the insulating material, the fiber material has a specific type of fabric structure formed, and has a strength within a fourth range, which is a strength range with a certain ratio of the weight of the first range according to the maximum thickness of the insulating material.

[0068] That is, the method for manufacturing the insulating material manufactures the insulating material (1) by introducing the fiber material at a weight within the first range at a certain ratio relative to the thickness, the organic material at a weight within the second range at a certain ratio relative to the weight of the insulating material (1) determined according to the thickness, and the precursor at a weight within the third range at a certain ratio relative to the weight of the insulating material (1) determined according to the thickness.

[0069] Additionally, the fiber material may have a strength within the fourth range at a certain ratio of the weight of the first range determined according to the maximum thickness.

[0070] In this way, the method for manufacturing the insulating material manufactures the insulating material (1) by introducing the fiber material, the organic material, and the precursor, respectively, at a certain ratio determined according to the thickness.

[0071] The specific composition conditions (R1) of the above-mentioned method for manufacturing the insulating material may be as shown in Fig. 4.

[0072] The above first range may be a weight range of 10 to 100 [%] relative to the thickness.

[0073] For example, when the thickness is 250 [um], the first range may be 25 [g] to 250 [g].

[0074] In this case, the step (S1) of forming the above-mentioned material may be performed by introducing the above-mentioned fiber material in a weight of 25 [g] to 250 [g].

[0075] The above second range may be a weight range of 10 to 14 [%] relative to the weight of the insulating material (1).

[0076] For example, when the weight of the insulating material (1) is 250 [g], the second range may be 25 [g] to 35 [g].

[0077] In this case, the step (S1) of forming the above-mentioned substrate may be performed by introducing the organic material in a weight of 25 [g] to 35 [g].

[0078] The third range may be a weight range of 15 to 45 [%] relative to the partial weight.

[0079] For example, if the partial weight is 100 [g], the third range may be 15 [g] to 45 [g].

[0080] In this case, the step (S2) of impregnating the substrate may be performed by impregnating the precursor in a weight of 30 [g] to 90 [g].

[0081] The fourth range may be a strength range that is twice the weight of the first range according to the maximum thickness of the insulation (1).

[0082] For example, when the first range according to the maximum thickness of 500 [um] is 50 [g] to 500 [g], the fourth range may be 100 [Mpa] to 1000 [Mpa].

[0083] In this case, the step (S1) of forming the above-mentioned material may be performed by introducing the above-mentioned fiber material having a strength of 100 [Mpa] to 1000 [Mpa].

[0084] Meanwhile, the specific form of the fiber material may include one or more forms of plain weave, twill weave, and main weave.

[0085] That is, the above-mentioned fiber material can be formed into a fabric structure of one or more types of plain weave, twill weave, and main weave.

[0086] In this way, the method for manufacturing the insulating material may be such that, in order to manufacture the insulating material (1) with a thickness of 500 [um] or less, the specific type of fabric structure is formed, the fiber material having a strength within the fourth range is introduced at a weight within the first range, and the organic material is introduced at a weight within the second range to form the substrate (S1), the precursor is impregnated into the substrate at a weight within the third range (S2), and the impregnation product in which the precursor is impregnated into the substrate is dried (S3), thereby manufacturing the insulating material (1).

[0087] Here, the drying step (S3) may include a process of gelling the impregnant to form a wet gel blanket and surface modifying the wet gel blanket.

[0088] Thereafter, the manufacturing of the insulating material (1) can be completed through a process of drying and heat-treating the dried material in the drying step (S3) under specific temperature and specific time conditions.

[0089] By manufacturing the above-mentioned insulating material (1) according to the above-mentioned method for manufacturing the above-mentioned insulating material, it is possible to manufacture an insulating material that secures insulating performance while being easy to process flexibly into a thin structure.

[0090] The insulating material (1) manufactured by the above-described method for manufacturing the insulating material can be used as a material for an insulating member placed in a specific space or specific structure within a home appliance.

[0091] Hereinafter, an example of a method for manufacturing an insulating member for manufacturing the above insulating member will be described.

[0092] <Method for manufacturing insulation materials>

[0093] An embodiment of the above method for manufacturing an insulating member is a method for manufacturing an insulating member to be placed in a specific space or specific structure within a home appliance using the insulating material (1) manufactured by the above-described method for manufacturing an insulating material.

[0094] Here, the home appliance may be a refrigerator, an air conditioner, an air purifier, a computer, etc., and the specific space or the specific structure may be a location where heat exchange takes place within the home appliance.

[0095] For example, it may be a compression chamber of the refrigerator or a door of the refrigerator.

[0096] The above insulating member (10) may be formed of a structure in which a plurality of insulating materials (1) are laminated, as illustrated in FIG. 5.

[0097] Here, at least one of the plurality of insulating materials (1) may be an insulating material having a thin thickness of 500 [um] or less.

[0098] That is, the insulating member (10) may have at least one insulating material with a thickness of 500 [um] or less laminated thereon.

[0099] The above insulating member (10) can be completed by laminating a coating material (4) by stacking the plurality of insulating materials (1) and applying pressure upward and downward.

[0100] The above insulating member (10) can be manufactured with a thickness according to the specific space or the specific structure.

[0101] For example, it can be manufactured to 15 [mm].

[0102] Meanwhile, at least one of the plurality of insulating materials (1) may be formed with a different thickness from the rest.

[0103] For example, when three insulating materials (1) are laminated, the first insulating material can be formed with a thickness A [mm] different from the thicknesses of the second and third insulating materials.

[0104] Additionally, each of the plurality of insulating materials (1) may be formed with different thicknesses.

[0105] For example, when three insulating materials (1) are laminated, the first insulating material can be formed with a thickness of A [mm], the second insulating material can be formed with a thickness of B [mm] different from A, and the third insulating material can be formed with a thickness of C [mm] different from A and B.

[0106] The method for manufacturing the insulating member (10) described above can be performed in the order shown in FIGS. 6 and 7 or in the order shown in FIGS. 8 and 9.

[0107] The above method for manufacturing an insulating member includes, as illustrated in FIG. 6, a step (S10) of manufacturing a plurality of insulating materials (1) with a thickness of 500 [um] or less, a step (S20A) of processing each of the plurality of insulating materials (1) into a shape of a placement position, and a step (S30A) of stacking the processed plurality of materials.

[0108] Here, the manufacturing step (S10) may be a step according to the insulating material manufacturing method (S1 to S3) as illustrated in FIG. 3.

[0109] In this way, the method for manufacturing the insulating member, as illustrated in FIG. 7, manufactures the plurality of insulating materials (1) with a thickness of 500 [um] or less (S10), processes each of the plurality of insulating materials (1) into a shape of a placement position (S20A), and stacks the processed plurality of materials (S30A), thereby manufacturing the insulating member (10).

[0110] In this way, by processing the plurality of insulating materials (1) into the shape of the arrangement position (S20A) and then stacking them (S30A), the difficulty of processing due to the complex structure of the arrangement position and the resulting damage to the insulating material during processing are prevented, and the insulating member (10) can be accurately manufactured into a structure according to the arrangement position.

[0111] In the manufacturing step (S10) of the above method for manufacturing an insulating member, the thickness of one of the plurality of insulating materials (1) can be manufactured to be different from the thickness of the other.

[0112] Accordingly, one of the plurality of insulating materials (1) laminated on the insulating member (10) may have a different thickness from the other.

[0113] In the above method for manufacturing an insulating member, the laminating step (S30A) can laminate the plurality of processed materials in order of thickness.

[0114] For example, the above-mentioned stacking step (S30A) can stack the plurality of processing materials starting from the processing material with the thickest thickness.

[0115] In this case, the insulating member (10) may have the thickest insulating material placed at the bottom and the thinnest insulating material placed at the top.

[0116] Accordingly, the vertical strength of the insulating member (10) can be stably formed.

[0117] In addition, the stacking step (S30A) may stack the plurality of processed materials in a manner other than the order of thickness, depending on the structure of the arrangement location or the use of the insulating member (10).

[0118] For example, the thinnest thickness of the workpiece may be stacked between two workpieces or on top.

[0119] By arranging the insulating material of such a thin thickness in a laminated structure, the thickness tolerance during compression can be minimized, thereby improving the strength of the insulating member (10).

[0120] The method for manufacturing the above insulating member also includes a step (S10) of manufacturing a plurality of insulating materials (1) with a thickness of 500 [um] or less, as illustrated in FIG. 8, a step (S20B) of laminating the plurality of insulating materials (1), and a step (S30B) of processing the laminated materials into a shape of a placement position.

[0121] Here, the manufacturing step (S10) may be a step according to the insulating material manufacturing method (S1 to S3) as illustrated in FIG. 3.

[0122] In this way, the method for manufacturing the insulating member is as illustrated in FIG. 9, after manufacturing the plurality of insulating materials (1) with a thickness of 500 [um] or less (S10), stacking the plurality of insulating materials (1) (S20B), and processing the stacked laminated materials into a shape of a placement position (S30B), thereby manufacturing the insulating member (10).

[0123] In this way, by stacking the plurality of insulating materials (1) (S20B) and processing them into the shape of the arrangement position (S30B), the difficulty of processing due to the complex structure of the arrangement position and the resulting processing difference between the plurality of insulating materials are prevented, and the insulating member (10) can be accurately manufactured into a structure according to the arrangement position.

[0124] In the above method for manufacturing an insulating member, the manufacturing step (S10) can manufacture one of the plurality of insulating materials (1) and another one with different thicknesses.

[0125] Accordingly, the thickness of at least one of the plurality of insulating materials (1) laminated on the insulating member (10) may be different from the thickness of the remaining ones.

[0126] In the above method for manufacturing an insulating member, the laminating step (S20B) may laminate the thickest and thinnest insulating materials among the plurality of insulating materials (1) at the bottom and top, respectively.

[0127] For example, the above-mentioned laminating step (S20B) can laminate the plurality of insulating materials (1) in the order of thickness from the bottom to the thickest insulating material.

[0128] In this case, the above insulating member (10) may be arranged such that the plurality of insulating materials (1) are arranged in order of thickness from the bottom to the top.

[0129] Accordingly, the vertical strength of the insulating member (10) can be stably formed.

[0130] In addition, the stacking step (S20B) may stack the plurality of processed materials in a manner other than the order of thickness, depending on the structure of the arrangement location or the use of the insulating member (10).

[0131] For example, the thinnest thickness of the workpiece may be stacked between two workpieces or on top.

[0132] By arranging the insulating material of such a thin thickness in a laminated structure, the thickness tolerance during compression can be minimized, thereby improving the strength of the insulating member (10).

[0133] The insulating member (10) manufactured by the above-described method for manufacturing the insulating member can be placed and utilized in the specific space or specific structure within the home appliance.

[0134] Hereinafter, an example of the insulating material (1) used as a material for the insulating member (10) will be described.

[0135] Insulation

[0136] The above-mentioned example of the insulating material may be an insulating material used as a material of the insulating member (10).

[0137] The above insulation material (1) is formed to a specific thickness of 500 [um] or less as shown in Fig. 1, and the exterior can be coated with the coating material (4).

[0138] The above insulating material (1) can be manufactured using the above-described insulating material manufacturing method.

[0139] The above insulating material (1) can be used as an insulating material in the method for manufacturing the insulating member described above.

[0140] The above insulating material (1) includes a substrate (2) formed of the fiber material and the organic material as shown in Fig. 2, and an aerogel (3) in which the precursor is gelled and dried.

[0141] The above-mentioned insulating material (1) can be manufactured using the insulating material manufacturing method illustrated in FIG. 3, but can be manufactured under the composition conditions illustrated in FIG. 4.

[0142] The above insulating material (1) can be manufactured to be formed with the above specific thickness of 100 to 500 [um].

[0143] For example, it can be manufactured with a thickness of 250 [um].

[0144] In this case, the insulating material (1) can be manufactured according to the composition conditions (R2) of the insulating member (10) as shown in Fig. 4.

[0145] In the above insulation material (1), the fiber material has a specific type of fabric structure formed and has a strength of 100 to 1000 [Mpa].

[0146] When the thickness of the above insulation material (1) is 250 [um], the strength of the fiber material may be 600 to 700 [Mpa].

[0147] Accordingly, when the insulating material (1) is formed with a thickness of 250 [um], the fiber material can have a strength of 600 to 700 [Mpa].

[0148] In the above insulation material (1), the fiber material is contained in a weight of 10 to 100 [%] relative to the length of the specific thickness.

[0149] When the thickness of the above insulation material (1) is 250 [um], the weight of the fiber material may be 240 to 280 [g].

[0150] Accordingly, when the insulating material (1) is formed to a thickness of 250 [um], the fiber material may be contained in a weight of 240 to 280 [g].

[0151] In the above insulating material (1), the organic material may be contained in a weight of 10 to 14 [%] relative to the weight of the insulating material (1).

[0152] When the thickness of the above insulation material (1) is 250 [um], the weight of the organic material may be 29 to 34 [g].

[0153] Accordingly, when the insulating material (1) is formed to a thickness of 250 [um], the organic material may be contained in a weight of 29 to 34 [g].

[0154] In the above insulating material (1), the precursor is contained in a weight of 15 to 45 [%] relative to the weight of the insulating material minus the weight of the organic material.

[0155] When the thickness of the above insulation material (1) is 250 [um], the weight of the precursor may be 102 to 120 [g].

[0156] Accordingly, when the insulating material (1) is formed to a thickness of 250 [um], the precursor may be contained in a weight of 102 to 120 [g].

[0157] In this way, the insulating material (1) manufactured to a specific thickness of 100 to 500 [um], in which the fiber material has a strength of 600 to 700 [Mpa] and is contained in a weight of 240 to 280 [g], the organic material is contained in a weight of 29 to 34 [g], and the precursor is contained in a weight of 102 to 120 [g], can be laminated in multiple pieces as shown in FIG. 5 to form the insulating member (10) arranged in a specific space or specific structure of the home appliance.

[0158] Hereinafter, as an example to which the above-mentioned insulating member (10) is applied, an embodiment of a pillar mounted on a door of a refrigerator, which is one of the above-mentioned specific space or the above-mentioned specific structure, will be described.

[0159] <Pillar mounted on the refrigerator door>

[0160] The above insulating member (10) can be placed in the specific space or specific structure of the home appliance.

[0161] For example, it can be applied to a pillar (100) mounted on a door (110) of a refrigerator as shown in FIG. 10.

[0162] The above insulating member (10) can be built into the pillar (100).

[0163] The above pillar (100) can be formed in a bar shape as shown in FIG. 11.

[0164] The above pillar (100) can rotate depending on whether the door (110) is opened or closed.

[0165] The above-mentioned pillar (100) can rotate when the door (110) and another door (120) are closed, as shown in FIG. 12, to seal the gap between the door (110) and another door (120).

[0166] That is, the above-mentioned pillar (100) can block the interior of the refrigerator from the outside in the gap between the door (110) and the other door (120) when the door (110) and the other door (120) are closed.

[0167] The above-mentioned pillar (100) includes a housing forming the exterior of the pillar (100) and an insulating member (10) inserted into the housing.

[0168] That is, the above-mentioned pillar (100) may have the insulating member (10) built into the interior of the housing as shown in FIG. 12.

[0169] The above insulating member (10) can be processed into the internal structure of the housing in order to be built into the interior of the housing.

[0170] The above insulating member (10) includes a plurality of insulating materials (1) laminated in the thickness direction of the pillar (100).

[0171] Each of the above plurality of insulating materials (1) may be the insulating material (1) described above.

[0172] The above-mentioned pillar (100) with the above-mentioned insulating member (10) built in can have an improved insulating effect compared to a conventional pillar without the above-mentioned insulating member (10) built in.

[0173] FIG. 13 is a diagram showing the temperature measurement results when the insulation member (10) is not built into the pillar (100), and FIG. 14 is a diagram showing the temperature measurement results when the insulation member (10) is built into the pillar (100). As shown in FIG. 12, the results of measuring the temperature at each temperature measuring unit (P) of the pillar (100), the door (110), and the other door (120) are shown, and the temperature of the pillar (100) is the result of measuring the temperature at each of some measuring points (2, 3, 5, 6) among the measuring points (1 to 7) of the pillar (100) as shown in FIG. 11.

[0174] When the insulation member (10) is not built into the pillar (100), that is, in the case of a pillar like the conventional one, the temperature in each of the pillar (100), the left door (110), and the right door (120) is measured as shown in FIG. 13, but when the insulation member (100) is built into the pillar (100), that is, in the case of the pillar according to the embodiment, the temperature in each of the pillar (100), the left door (110), and the right door (120) is measured as having increased in all parts as shown in FIG. 14, and it can be confirmed that the insulation effect of the pillar according to the embodiment is improved as compared to the case where the insulation member (10) is not built into the pillar as shown in FIG. 15.

[0175] In this way, by embedding the insulating member (10) in the pillar (100), the insulating effect of the pillar (100) is improved, thereby increasing the insulating performance of the refrigerator.

[0176] In addition, by applying the insulating material (10), the loss of cold air in the refrigerator is prevented and maintained at a constant level, thereby enabling the stored items to be kept fresh, thereby improving product reliability and user satisfaction. In addition, by increasing the insulating performance, power consumption is reduced, thereby improving energy consumption efficiency.

[0177] So far, the method for manufacturing an insulating material, the method for manufacturing an insulating member, and embodiments of the insulating material and the pillar have been described, but the described embodiments can be modified in various ways without departing from the scope of the present invention, and the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims described below but also by equivalents of the claims.
