Problems solved by technology
[0006] However, this type of seal has insufficient durability, impact resistance, etc. with long-term use of more than 15 years, so it is limited in maintaining the high vacuum state inside the vacuum heat-resistant material, so it is not suitable for long-term use. More than 30 years of vacuum heat-resistant materials for construction

Embodiment 1～4 and comparative example 1～4
[0053] A multilayer structure film was prepared with the type and thickness of the layer structure shown in Table 1 below. Use two-component urethane adhesive (base material: polyester urethane polyol, curing agent: aromatic polyisocyanate) when bonding each layer, and coat it on the bonding surface by gravure printing After that, the bonding is carried out in a laminated manner. The type, amount, and bonding conditions of the adhesive used for bonding of each layer are the same.
[0054] In Examples 1 to 4 and Comparative Examples 1 to 2, the same adhesive as the above was used on the prepared multilayer structure film, and glass fiber cloth was bonded by gravure printing to prepare a sealing member. In Comparative Examples 3 to 4, the obtained multilayer structure film was directly used as a sealing member without bonding the glass fiber cloth.
[0055] The prepared seals were used as the outer skin material, and the glass wool core material prepared by needle punching and the ...

Abstract
The present invention relates to an outstandingly impact resistant and incombustible vacuum-insulation-material sealing member, and, more specifically, relates to a vacuum-insulation-material sealing member comprising: glass cloth; a first outer layer selected from an inorganic oxide-deposited PET layer, a nylon layer and a deposited OPP layer; a second outer layer selected from an inorganic oxide-deposited PET layer, a nylon layer and a deposited OPP layer; an aluminum foil layer; and a polyethylene hot-melt-bonding layer, whereby it is possible to provide a vacuum-insulation material which not only is outstandingly impact resistant and incombustible but also prevents physical-property deterioration and occurring of pinholes due to long-term use of the vacuum insulation material and affords high levels of physical-property reliability and durability.
Description
Technical field [0001] The present invention relates to a sealing member of a vacuum heat-resistant material with excellent impact resistance and non-combustibility. More specifically, it relates to a sealing member of the following vacuum heat-resistant material, which includes glass cloth (GlassCloth, glass cloth), The first outer layer, the second outer layer, the aluminum foil layer and the polyethylene heat-fusion layer, the first outer layer is selected from the group consisting of inorganic oxide vapor-deposited polyethylene terephthalate (PET) layer and nylon layer And vapor-deposited oriented polypropylene (OPP) layer, the second outer layer is selected from inorganic oxide vapor-deposited PET layer, nylon layer and vapor-deposited OPP layer, the vacuum heat-resistant material seal is not only impact resistance and It has excellent incombustibility, and prevents the deterioration of physical properties of the vacuum heat-resistant material and the generation of pinholes...
