Problems solved by technology

[0008] However, when using a bag-shaped cover material, it is necessary to make the above-mentioned cover material larger in order to introduce the uncompressed core material into the inside of the cover material, and if the size of the cover material is increased, the inside of the cover material must be decompressed. The disadvantage of a lot of unwanted residual area of ​​the skin material
[0009] Therefore, the above-mentioned core material needs to be inserted into the outer skin material of the bag form after being compressed once, but the above-mentioned core material will recover to a certain extent during the process of inserting the compressed core material into the outer skin material, so there is a limit to the size of the miniaturized outer skin material. The problem

Embodiment 1

[0071] The core material containing the gas adsorbent is compressed under low vacuum and inserted into the outer skin material in the form of a bag, and the core material is 1.0×10 -3 torr vacuum packaging to make vacuum insulation.

[0072] At this time, the structure of each surface of the above-mentioned skin material is as shown in Table 1 below, and the gas adsorbent and core material are the same as those of Comparative Example 1.

[0075] Vm-PET: aluminum-evaporated polyethylene terephthalate (PET)

[0076] LLDPE: Linear Low Density Polyethylene

[0077] From the experimental results in Table 1, in order to minimize the excess area of ​​the outer skin material of the vacuum insulation material, when performing plate-shaped compression (compression in which a plate is placed on the upper end of the core material and pressed with UTM or similar force), the fiber The dust rate shows 0.95% and 0.44% when compressed under low vacuum. That is ...

Abstract

After the method for manufacturing vacuum insulator according to the invention settles the core in the jig upper side of panel in which the upper side is covered with the compression film and it discharges air between the jig panel and the compression film and it compresses the core it pressurizes the core in the state inserting all or part of the jig panel inside the coating material of the form of pouch and it leads inside the coating material and it seals up the opening part of the coating material since exhausting the air within the coating material. The vacuous insulator manufacturing device according to the invention comprises the jig panel of the flat pattern in which the core is possible to mount in the upper side; the rest three-way edge except for one side or the compression film in which the other side edge is closely connected to the jig panel the core settled in the jig upper side of panel is covered; the jig panel; and the pressing unit which pushes the vacuum pump forming the vacuum pressure between the compression film and compresses the core and the core compacted by the vacuum pump with one side and discharged.

Description

technical field [0001] The present invention relates to a manufacturing method and manufacturing apparatus of a vacuum heat insulating material, and more particularly, to a manufacturing method and apparatus of a vacuum heat insulating material in which thermal insulation is improved by narrowing a margin portion and reducing a dust rate. Background technique [0002] Vacuum insulation material is a material that vacuum-processes the inside of the insulation material to block the convection phenomenon inside the insulation material, making it a material that exhibits an excellent insulation performance that is more than five times that of the existing organic / inorganic insulation materials. [0003] like figure 1 and figure 2 As shown, the structure of a common vacuum insulation material 10 generally includes: a core material (core material) 12; a skin material 11, which is composed of a multilayer film (multi layer film) and wraps the core material; a gas adsorbent (gette...
