preparation example Construction

[0038] The preparation method of the core material for the vacuum heat insulation panel of the present invention firstly dips the glass wool (Glass Wool) in the solution mixed with the inorganic binder, and then fishes out the glass wool that has absorbed the inorganic binder solution. After that, the drying process is carried out while removing the residual inorganic binder.

[0039] Secondly, a skin material having a laminated structure of a surface protection layer, a metal barrier layer and an adhesive layer is formed.

[0040] Next, an absorbent prepared by packing quicklime (CaO) powder in a bag was formed.

[0041]Next, the above-mentioned absorbent is attached to the upper part of the above-mentioned core material or the above-mentioned absorbent is inserted into the surface of the above-mentioned core material, and the bag is formed with the above-mentioned outer skin material, and then the core material is put into the bag and sealed in a vacuum state. Vacuum insula...

Embodiment 1

[0075] First, the above image 3 The glass wool type (Glass Wool Type) core material described in is prepared into a size of 25×300×400 mm (thickness×width×length) and used as a core material for vacuum insulation panels.

[0076] Here, the inorganic binder solution for impregnating glass wool uses silica as an inorganic binder, and prepares the silica in a sol form to be thoroughly mixed in water. Next, an aqueous silica sol solution obtained by mixing 4% by weight of silica sol and the rest of water was prepared.

[0077] Next, an external bag is formed, which is made of 12 μm polyvinylidene chloride (PVDC) / polyethylene terephthalate (PET) film, 25 μm nylon (Nylon) film, 6 μm Al Foils as well as 50 μm linear low density polyethylene (LLDPE) film structures were formed.

[0078] Next, if Figure 6 As shown, two absorbents were inserted on the surface of the core material, wherein the absorbent was prepared by packing 25 g of quicklime (CaO) with a purity of 95% into a bag....

Embodiment 2

[0081] Prepare a vacuum insulation panel with the same conditions as in Example 1 above, using an aqueous solution of silica sol mixed with 2% by weight of silica sol and the rest of water.

Abstract

The present invention relates to a core material for a vacuum insulation panel and a manufacturing method for same, and comprises the following steps: (a) preparing an inorganic binder solution; (b) dipping glass wool into the inorganic binder solution; (c) loading the glass wool onto the upper portion of a chamber; (d) creating a vacuum inside the chamber in order to discharge the inorganic binder solution into the chamber; and (e) drying the glass wool and molding it into the form of the core material for manufacturing a vacuum insulation panel, thus enhancing the long-term durability of the vacuum insulation panel.

Description

technical field [0001] The present invention relates to a core material for a vacuum heat insulation panel and a preparation method thereof, and relates to a method for preparing a core material constituting a vacuum heat insulation panel through an inorganic binder solution dipping method (Dipping Process) using glass wool, reconstituting the outer skin material and Absorbent raw material and interlayer structure to produce vacuum insulation panels with long-term durability and low thermal conductivity. Background technique [0002] Vacuum Insulation Panel (Vacuum Insulation Panel) is produced as follows: a bag made of a composite plastic laminated film with excellent gas barrier properties is accommodated as a core material, such as open-cell rigid plastic foam or inorganic materials, and the inside is sealed. After the decompression, the laminated portion between the gas barrier films at the peripheral edges was heat-sealed, thereby preparing a vacuum insulation panel. ...
