Description

[Technical field]

[0001] The present invention relates to a heat shield sheet. [Background technology]

[0002] Heat shielding sheets made of glass fiber or the like with aluminum foil on both sides are widely used both indoors and outdoors, but they are not particularly suitable for outdoor use because they are not strong or durable. In addition, the aluminum foil causes discomfort due to reflected light, and the workability is poor. Summary of the Invention [Problem to be solved by the invention]

[0003] The present invention has been made in consideration of the above circumstances, and has an object to provide a heat shielding sheet that is strong, durable, does not cause discomfort due to reflected light, and is easy to apply. [Means for solving the problem]

[0004] The present invention provides a heat shield sheet having an aluminum foil layer and protective resin layers on both sides thereof.

[0005] The front protective resin layer is made thick by forming two layers through the base fabric, which increases the surface strength and blocks the reflected light of the aluminum foil, making it suitable for outdoor use. The front protective resin layer is colored, which enhances the design, making it suitable for outdoor use. The heat-shielding effect is enhanced by using multiple aluminum foil layers, and the thickness of the aluminum foil is about 15 to 50 μm. Aluminum foil Effect of the Invention

[0006] According to this invention, the heat shielding sheet has excellent strength and durability, and does not cause discomfort due to reflected light from the aluminum foil, so it can be used outdoors without any problems. In addition, it can be heat-sealed or sewn, and is easy to install, so it can be used conveniently. In particular, when used outdoors, the colored front protective resin layer is used on the outer surface, which gives it an excellent design. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is an enlarged partial schematic diagram of an embodiment of the heat shield sheet of the present invention. [Diagram 2] FIG. 1 is an enlarged partial schematic diagram of another embodiment of the heat shield sheet of the present invention. Preferred embodiments of the invention

[0008] FIG. 1 shows a heat shielding sheet 1 according to a first embodiment of the present invention, in which a front protective resin layer 4 and a back protective resin layer 5 are attached to both sides of an aluminum foil layer 2, and the aluminum foil layer 2, the front protective resin layer 4, and the back protective resin layer 5 are each bonded and fixed by dry lamination processing with an adhesive 6. The aluminum foil layer 2 is formed by bonding and fixing aluminum foils 10 and 11 to both sides of a base fabric layer 14 made of glass fiber or polyethylene fiber. The front protective resin layer 4 is formed by welding and fixing first and second protective resin layers 8 and 9 with a base fabric layer 7 made of glass fiber or polyethylene fiber sandwiched therebetween. The first and second protective resin layers 8 and 9 forming the front protective resin layer 4 and the back protective resin layer 5 are both made of urethane resin or vinyl chloride resin. The front protective resin layer 4 is made of a color tone such as white or ivory.

[0009] As described above, both sides of the aluminum foil layer 2 of the heat shielding sheet 1 are covered and protected by the front protective resin layer 4 and the back protective resin layer 5. This gives the heat shielding sheet 1 excellent strength and durability, and since there is no discomfort caused by reflected light from the aluminum foils 10 and 11, it can be used outdoors without any problems. In addition, it can be heat-sealed and sewn, and is easy to install, making it convenient to use. In particular, when used outdoors, the colored front protective resin layer 4 is used as the outer surface, resulting in an excellent design.

[0010] FIG. 2 shows a heat shielding sheet 1 according to a second embodiment of the present invention, in which a front protective resin layer 4 and a back protective resin layer 5 are attached to both sides of an aluminum foil layer 2, and the aluminum foil layer sheet 2 is bonded and fixed to the front protective resin layer and the back protective resin layers 4 and 5 by dry lamination processing using an adhesive 6. The aluminum foil layer 2 is composed of an aluminum foil 10, a base fabric layer 14 made of glass fiber or polyethylene fiber, a heat insulating layer 20 formed of felt made of flame-resistant fiber, polyester fiber, polyethylene fiber, etc., a base fabric layer 14 made of glass fiber or polyethylene fiber, and an aluminum foil 11, which are bonded and fixed in this order. The front protective resin layer 4 is formed by welding and fixing the first and second protective resin layers 8 and 9 with a base fabric layer 7 made of glass fiber or polyethylene fiber sandwiched therebetween. The front protective resin layer 4 and the back protective resin layer 5 are both made of urethane resin or vinyl chloride resin. The front protective resin layer 4 is made of a color tone such as white or ivory.

[0010] The heat shielding sheet 1 described above exhibits the same effects as those of the first embodiment, and also exhibits a heat insulating effect due to the presence of the heat insulating layer 20 made of felt. [Explanation of symbols]
