HEAT-INSULATION FILM FOR HIGH TEMPERATURE MOLDING, VACUUM THERMAL INSULATOR USING SAME AND PROCESS FOR FABRICATING VACUUM THERMAL INSULATOR

摘要

Disclosed are a heat-insulation film laminated with formability at a high temperature, a vacuum thermal insulator covered on an outer portion of a core material of the heat-insulation film, and a method of fabricating the vacuum thermal insulator in which the heat-insulation film is covered on the outer portion of the core material through the thermal-fusion process. The heat-insulation film is stably covered on the outer portion of the core material through the thermal-fusion process at the high temperature.

1. A heat-insulation film comprising:
a first film layer comprising a material selected from the group consisting of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polyimide (PI); a first barrier layer laminated on one surface of the first film layer through a first bonding layer comprising a material selected from the group consisting of linear low density polyethylene (LLDPE), low density polyethylene (LDPE), high density polyethylene (HDPE), casted polypropylene (CPP), polyethylene, polyethylene terephthalate (PET), polypropylene (PP), ethylene vinyl acetate (EVA), epoxy resin, and phenol resin; and a hot-melt layer laminated on an opposite surface of the first barrier layer and comprising a material selected from the group consisting of linear low density polyethylene (LLDPE), low density polyethylene (LDPE), high density polyethylene (HDPE), casted polypropylene (CPP), polyethylene, polyethylene terephthalate (PET), polypropylene (PP), ethylene vinyl acetate (EVA), epoxy resin, and phenol resin.
