To a heat insulating film.
Thermal Insulation is generally used to block heat, which can be used to reduce heat loss and heat absorption when used in buildings, thus saving energy consumption for heating and cooling.
Further, the heat insulating material can greatly reduce heat flow due to conduction, convection and radiation, thereby preventing condensation due to temperature difference and minimizing changes in room temperature.
1 is a perspective view and a development view showing a piping insulation material according to the prior art document 1.
As shown in FIG. 1, the insulation material for a pipe according to the prior art document 1 includes a synthetic resin foam foam 20 that maintains the temperature in the pipe B made of a pipe or a duct and a synthetic resin foam foam 20 which is attached to the outside of the synthetic foam foam foam 20 And an outer heat insulating foil (10).
The synthetic foam foams 20 may be made of polyethylene (PE), which is an eco-friendly material and excellent in thermal insulation, and the outer heat-insulating foil 10 may be an aluminum film or a silver-deposited film. And the effect of moisture and heat can be expected by eliminating the phenomenon that outside heat and cold air are directly transmitted to the pipe (B), thereby preventing the influence of the moisture on the pipe (B).
However, the outer heat-insulating foil 10 according to the prior art document 1 is made of only an aluminum film or a silver-deposited film and has a weak tensile force, so that it faces many difficulties when it is joined with the synthetic foam foam 20.

The reflection type heat insulating material having flame retardancy according to the prior art document 2 is made of any one of polypropylene (PP) resin, polyethylene (PE) resin and low density polyethylene (LDPE) resin as shown in Figs. 2A to 2C. Of a flame retardant resin mixture of 40 to 40% by weight of a flame retardant resin, 58 to 62% by weight of a flame retardant selected from the group consisting of an organic flame retardant and an inorganic flame retardant, and 1 to 3% by weight of an antioxidant, An air layer surrounded by the barrier rib 212 and the reflective film 220 to form a heat shielding action and a barrier rib 212 having a thickness of the porous net shape and a hole 211 formed thereon, An insulating foam 210; A reflection film 220 attached to the upper and lower surfaces of the flame-retardant insulating foam 210 by a heat fusion method and made of an aluminum film having a heat ray reflection performance; And a corrosion-resistant thin-film coating layer 230 formed by thinly coating polyester (PET) resin with a thickness of 0.5 ± 0.1 μm on the surface of the reflective film 120 exposed to the air.
However, the reflective film 220 according to the prior art document 2 is also made of an aluminum film, so that it is difficult to apply the flame retardant insulating foam 210 to the flame retardant insulating foam 210.

A preferred embodiment of the flame retardant insulating film according to the present invention will be described with reference to the drawings, and there can be a plurality of embodiments thereof, and the objects, features and advantages of the present invention can be better understood through these embodiments .
3 is a structural view showing a conventional heat insulating film.
As shown in Fig. 3, a typical heat insulating film has a structure in which heat is applied between the aluminum foil (A) and the glass fiber sheet (G) while interposing a polyester film (P)
However, although the glass fiber sheet (G) is a nonflammable material, it is harmful to the human body when used for a long period of time. Particularly, the polyester film (P) .
The applicant of the present application proposed a new type of flame retardant insulating film, which is a slight change, since conventional insulating films harmful to human bodies are inevitably dangerous when used in the production of heat insulating materials for various buildings.
4 is a structural view showing a flame retardant insulating film according to the present invention.
4, the flame retardant insulating film according to the present invention comprises a flame retardant fiber sheet 10 flexibly bent at the same time as having heat resistance and tensile strength and laminated with a flame retardant adhesive 20 on the upper and lower surfaces of the flame retardant fiber sheet 10, And an upper aluminum foil 31 and an under aluminum foil 32 which are joined together.
The flame retardant fiber sheet 10 can be made of a flame retardant nonwoven fabric sheet made of PET, PE, or PP containing a flame retardant component or a flame retardant woven sheet and has heat resistance that can endure at about 400 DEG C. Particularly, So that the tensile limit of the upper aluminum foil 31 and the under aluminum foil 32 can be supplemented and supplemented while flexibly bending and supplied in a roll form.
At this time, when the upper aluminum foil 31 or the under aluminum foil 32 is laminated on either the upper surface or the lower surface of the flame retardant fiber sheet 10, the flame retardant fiber sheet 10 is heat- The upper aluminum foil 31 and the under aluminum foil 32 are provided on the upper and lower surfaces of the flame retardant fiber sheet 10 in the present invention, It is possible to maximize the effect of heat insulation by blocking reflection to heat radiation.
Particularly, it is possible to laminate the upper aluminum foil 31 and the under-aluminum foil 32 with the flame retardant fiber sheet 10 as the flame-retardant adhesive 20 without using a polyester film as a normal heat- The flame-retardant adhesive 20 can be applied to the flame-retardant adhesive of Patent No. 0816315, for example.
On the other hand, when the thickness of the flame retarded fiber sheet 10 is 6 μm or less, the strength of recognition becomes weak. When the thickness of the flame retardant fiber sheet 10 is 14 μm or more, the flexibility is weakened. In the present invention, Mu m.
Furthermore, it is preferable that the upper aluminum foil 31 and the under aluminum foil 32 have a thickness of 6 to 12 탆.
If the thickness of the upper aluminum foil 31 and the under-aluminum foil 32 is also 6 μm or less, the tensile force is too weak to perform the lyning bonding work with the flame retardant fiber sheet 10. If the thickness is 12 μm or more, .
The flame retardant heat-insulating film according to the present invention has a high tensile strength even when it is not burned in a fire but can be easily combined with various synthetic resin foamed foams, thereby maximizing productivity.
INDUSTRIAL APPLICABILITY The present invention can be used in an industrial field in which a thermal insulation finishing material of a building, a pipe for supplying liquid or gas, a duct for supplying hot or cold air at a low temperature, and the like can be insulated.
