Problems solved by technology

[0006] However, a vacuum insulation material made of the above-mentioned outer packaging material is suitable for use in a place where the environment in which it is used is not harsh, such as a refrigerator, or in an environment where it is not subject to external impact, but there are limitations in use as a vacuum insulation material for buildings.
When it is used for construction, the outer packaging material of the vacuum insulation material is damaged due to external impact and / or the core material is broken due to the problem of breaking the vacuum and difficulties in construction, etc. Therefore, the existing vacuum insulation material There are limitations in use for construction, and there is a problem that the heat insulation effect is significantly reduced due to the construction in a state where the vacuum is broken.
[0007] In recent years, according to the building energy-saving policy, the Korean thermal insulation regulations for new buildings aim at the popularization of Passive Houses in 2017, and strengthen supervision in the direction of reducing thermal transmittance (Passive Houses: annual heating energy consumption is less than 15kwh / m 2 (Oil consumption is 1.5l / m 2 ) buildings), in the case of using ordinary heat insulating materials in response to the government's building energy saving policy, it is necessary to use heat insulating materials with a thickness of approximately 240 mm, and thus there is a problem that the internal effective use area is significantly reduced
[0008] In addition, in the case of a building insulation panel in which a foaming component is applied to the outer layer of a conventional outer wrapping material in order to bond the foaming heat insulating material and the foaming component to each other, and a foam layer such as polystyrene is formed on the upper part Although it is effective in preventing impact and damage, there are problems in that the thickness of the wall increases due to the thickening of the heat insulating material, and the productivity and cost for forming the foam layer decrease.
[0009] In addition, although the outer packaging material of the vacuum insulation material using glass fiber has excellent flame retardancy, it has the disadvantages of high cost and heavy weight.

Embodiment 1

[0098] Example 1: Manufacture of outer packaging material for vacuum insulation panels

[0099] 1) Apply an adhesive (carbamic acid Ethyl ester (Urethane) binder), by laminating the co-extruded film produced in the above-mentioned preparatory example 1 to produce film 1 (co-extruded film layer→adhesive layer→first moisture barrier layer (VM-PET) ).

[0100] 2) Next, apply polyester-based urethane to one side of a polyethylene terephthalate film (PET film, trade name: PP900, manufacturer: Hyosung, average thickness 12 μm) using the same dry lamination method After the ethyl ester two-component adhesive, the film 2 is produced by laminating on the above film 1 (co-extruded film layer→adhesive layer→first moisture barrier layer (VM-PET)→gas barrier layer (PET)) .

[0101] 3) Then, use the same dry lamination method to apply polyester-based urethane two-component adhesive on one side of the above-mentioned film 2, and then laminate the polyester aluminized film (trade name: CGV...

Embodiment 2

[0104] The outer packaging material was produced in the same manner as in Example 1 above, but when forming the gas barrier layer, a nylon film (NY, trade name: RT92, manufacturing company: Hyosung, average thickness of 15 μm) to produce the film 2, and then use the above-mentioned film 2 to produce an outer packaging material in the same manner as in Example 1.

Embodiment 3

[0106] Film 2 of Example 1 above was produced in the same manner.

[0107] Then, after coating the top of the second moisture barrier layer of the film 2 with an isocyanate-based water-based acrylic paint (Soda, T-160), dry it to form a water-based acrylic coating, and then use a T-die at 300°C to 330°C ( T-die) Polyethylene resin is melted and extruded between the formed film 2 and non-woven fabric (trade name: C3030NW, manufacturer: Kolon, average thickness 70 μm) to produce an outer packaging material (co-extruded film layer → Adhesive layer → first moisture barrier layer (VM-PET) → adhesive layer → gas barrier layer (PET) → adhesive layer → second moisture barrier layer (VM-PET) → water-based acrylic coating → poly Vinyl layer (PE layer) → non-woven fabric layer).

Abstract

The invention relates to an outer packaging material for a vacuum insulation panel, a building vacuum insulation panel using the same and a manufacturing method of the building vacuum insulation panel, and particularly relates to a building vacuum insulation panel and a manufacturing method thereof. Compared with insulating panels at present, the vacuum insulation panel manufactured by utilizing the outer packaging material is better in light weight performance, and can minimize structural strengthening, and the available application space in a building can be larger than that of a building utilizing insulating panels at present.

Description

technical field [0001] The present invention relates to a new type of vacuum insulation panel, a method of manufacturing the same, and an outer packaging material for vacuum-packing the core material of the above-mentioned panel. The heat insulation board increases the effective use area inside the building and has excellent heat insulation effect. Background technique [0002] Generally, glass wool (or glass fiber, etc.) is used as the inner core material for vacuum insulation materials, and metal materials such as ultra-thin stainless steel plates are used as outer packaging materials. Excellent, thus having the advantage of preventing a decrease in thermal insulation performance. However, the density of this vacuum insulation material board is as thick as 200 to 300 kg / m 3 It is not easy to handle, and because the joint portion of the vacuum insulation material is sharp, there is a problem of risk factor, and the problem of poor welding of the joint portion of the outer...
