Provided is an outer covering material for a vacuum heat insulation material, the outer covering material having a laminated structure which sequentially, from the top, comprises: a protecting layer; a barrier layer; and a sealing material, wherein the barrier layer comprises: a polyethylene terephthalate (PET) resin film on which an aluminum oxide film is deposited; and an ethylene vinyl alcohol (EVOH) resin film on which a metal thin film is deposited. Provided is a vacuum heat insulation material, comprising: a core material consisting of glass fibers; and the outer covering material which houses the core material and decompresses the inner portion thereof.

Outer covering material for vacuum heat insulation material and vacuum heat insulation material comprising same

The present invention provides a glass fiber board comprising a glass fiber and an inorganic binder, wherein the inorganic binder comprises an aluminum phosphate. The present invention provides a method for preparing the glass fiber board comprising (a) preparing an inorganic binder solution comprising an aluminum phosphate (b) applying the inorganic binder solution comprising the aluminum phosphate to a glass fiber; (c) compressing the glass fiber to which the inorganic binder solution comprising the aluminum phosphate is applied; and (d) drying the compressed glass fiber.

Glass fiber board comprising inorganic binder and method for preparing the same

The present invention relates to a glass fiberboard and to a production method therefor, and more specifically, to technology for providing a glass fiberboard for vacuum heat insulation and a production method therefor, which have outstanding initial heat insulation performance and economic advantages through application of an optimized inorganic binder.

Glass fiberboard and production method therefor

The present invention relates to a vacuum insulation material including an inner bag and to a method for manufacturing same. The method for manufacturing the vacuum insulation material includes: a step of manufacturing a core material; a step of compressing and packing the entire surface of the core material using an inner bag made of a breathable film material; a step of disposing a getter on the upper portion of the inner bag; and a step of vacuum-packing a covering material on the upper portion of the inner bag. The inner bag is made of polypropylene (PP), polyester (PET), and/or polyethylene. Since the inner bag is manufactured using a breathable film having fine holes, the method for manufacturing the vacuum insulation material may have improved efficiency, and the vacuum insulation material may be improved in terms of the long-term durability and vacuum insulation properties thereof.
