The present invention relates to a groove-type vacuum insulation material and a method of manufacturing the same. The groove-type vacuum insulation material includes core materials each having a block shape, at least one lateral wall of which has an inclined surface; a groove-type insulation board, in which the core materials are arranged on a plane of the board to be separated from each other, with the inclined surfaces thereof facing each other; an outer skin material formed in a film pouch shape and surrounding the entirety of upper and lower sides of the groove-type insulation board, the outer skin material being brought into close contact with the groove-type insulation board by vacuum-sealing, and exhibiting bending characteristics in a space between the core materials. The present invention also relates to a method of manufacturing the same.

1. A vacuum insulation material, comprising: core materials each having a block shape and at least one lateral wall of which has an inclined surface;an insulation board, in which the core materials are arranged on a plane of the board to be separated from each other, with the inclined surfaces thereof facing each other;an outer skin material in a film pouch shape and surrounding an entirety of upper and lower sides of the insulation board, the outer skin material being in close contact with the insulation board, and capable of bending in a space between the core materials,wherein the inclined surfaces of adjacent core materials, facing each other, are configured to directly contact each other when the outer skin material is bent, andwherein a part of the outer skin material is configured to be bent and to protrude outward through the space between the core materials. 2. The vacuum insulation material of claim 1, wherein the core material comprises one or more selected from the group consisting glass wool, silica boards, glass boards, and polyurethane (PU) foam. 3. The vacuum insulation material of claim 1, wherein the core material include one planar shape selected from among triangular, rectangular, circular and polygonal planar shapes. 4. The vacuum insulation material of claim 1, wherein an angle between the inclined surface and a bottom of the core material is in the range of 15 to 60 degrees. 5. The vacuum insulation material of claim 1, wherein the outer skin material comprises at least one material selected from the group consisting linear density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), chlorinated polypropylene (CPP), and oriented polypropylene films. 6. The vacuum insulation material of claim 1, wherein the outer skin material has flexibility in the space between the core materials, and a joined portion of the outer skin material is formed coplanar with a bottom of the core materials. 7. The vacuum insulation material of claim 1, wherein each of the core materials comprises a plurality of stacked sheets. 8. The vacuum insulation material of claim 1, wherein each of the core materials comprises a single block. 9. The vacuum insulation material of claim 1, wherein the outer skin material comprises a material selected from the group consisting of linear low density polyethylene (LLDPE), chlorinated polypropylene (CPP), and oriented polypropylene films. 10. The vacuum insulation material of claim 1, wherein the outer skin material comprises two materials selected from the group consisting of linear low density polyethylene (LLDPE), chlorinated polypropylene (CPP), and oriented polypropylene films. 11. The vacuum insulation material of claim 1, wherein the outer skin material comprises linear low density polyethylene (LLDPE), chlorinated polypropylene (CPP), and oriented polypropylene films. 12. A method of manufacturing a vacuum insulation material, comprising: forming core materials each having a block shape and at least one lateral wall of which has an inclined surface;forming an insulation board, in which the core materials are arranged on a plane of the board to be separated from each other, with the inclined surfaces thereof facing each other, wherein the inclined surfaces facing each other are configured to directly contact each other when an outer skin material is bent, and wherein a part of the outer skin material is configured to be bent and to protrude outward through the space between the core materials;inserting the insulation board into the outer skin material through an opening at one side of the outer skin material having a pouch shape;evacuating the outer skin material through the opening in a vacuum chamber to provide a vacuum;forming a vacuum insulation material by sealing the opening under a vacuum; andheating the vacuum insulation material after moving the sealed vacuum insulation material from the vacuum chamber to an oven. 13. The method of claim 12, wherein the core material comprises one or more selected from among glass wool, silica boards, glass boards, and polyurethane (PU) foam. 14. The method of claim 12, wherein the outer skin material comprises at least one material selected from among linear density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), chlorinated polypropylene (CPP), and oriented polypropylene films. 15. The method of claim 12, wherein the sealing the opening comprises finishing the opening of the outer skin material by thermal sealing. 16. The method of claim 12, wherein the heating the vacuum insulation material comprises heating the vacuum insulation material at a temperature of 150˜200° C. 17. The method of claim 12, wherein the heating the vacuum insulation material comprises heating the vacuum insulation material by infrared radiation heating or hot wind heating. 18. The method of claim 12, wherein the oven comprises a vacuum oven. 19. The method of claim 12, wherein the forming the insulation board comprises arranging the core materials on a plane of a base film, and the base film comprises the same material as a thermal deposition layer of the outer skin material.
