In general, a glass window is installed in a building for lighting and ventilation. However, due to the low thermal insulation properties of the glass window, heat loss occurs through the glass window, which increases the cost of heating and cooling. In particular, since the winter season is longer than the summer season, many families feel a significant economic burden due to the heating cost in the winter season.

Recently, although a double-structured insulating glass window is installed in order to reduce heating costs, the double-structured insulating glass window requires a lot of cost to construct, and in the case of an existing house, it is inconvenient to have to perform a separate construction.

Accordingly, in order to solve the above problems, a heat insulating sheet for imparting heat insulation to a building has been disclosed.

However, since the conventional insulating sheet has a structure in which a plurality of air pockets are simply formed on a resin sheet attached to a glass window, the process of forming the air pockets on the resin sheet is very complicated and costly.

In addition, since the conventional heat insulating sheet has a structure in which the air pocket protrudes convexly on one surface of the resin sheet, even if it has a transparent color, the refractive index is severely generated and visibility from inside and outside is not secured, and the unique function of the glass window is lost. There is a problem being

In addition, when dew condensation occurs between the resin sheet and the glass window, the conventional insulating sheet has a problem in that the adhesive surface of the resin sheet is contaminated by moisture in the air, so that moisture absorptive and desorptive properties are reduced, mold is generated, and formaldehyde is emitted, which is not environmentally friendly.

The photoinitiator is preferably used in an amount of 0.1 to 3 parts by weight based on 100 parts by weight of the acrylate compound. When the content is less than 0.1 parts by weight, the polymerization rate is slow and the conversion rate is low, and when used in excess of 3 parts by weight, the reaction rate is Although it is fast, there are many oligomers of low molecular weight, and the physical properties of the adhesive are reduced.

Then, optionally, the dot-type adhesive 120 of the second insulating sheet 100-2 according to a modification of the preferred embodiment of the present invention is attached to the other surface of the resin sheet 110 of the first insulating sheet 100-1. Through this, one surface of the second thermal insulation sheet 100-2 is attached to the first thermal insulation sheet 100-1 while having an air layer, so that the thermal insulation property can be further improved.

Here, as the first function providing layer 130 is applied to one surface of the resin sheet 110 of the first insulating sheet 100-1 and the second insulating sheet 100-2, even if dew condensation is generated by the air layer, the resin sheet (110) moisture absorptive and desorptive properties, anti-fungal properties and formaldehyde dissipation inhibitory properties are provided to maintain environmentally friendly conditions.

In addition, the second heat insulating sheet 110-2, the anti-collision pattern 140 does not need to be printed on one surface or the other surface of the resin sheet 110.

On the other hand, when the heat insulating sheet 100 is attached to the outside of the glass window 10, the dot-type adhesive 120 of the second heat insulating sheet 100-2 according to a modified example of the preferred embodiment of the present invention is applied to the glass window 10. ), one side of the resin sheet 110 is attached to the glass window 10 while having an air layer, so that heat insulation is provided.

Here, as the anti-collision pattern 140 is printed on one surface or the other surface of the resin sheet 110 of the second heat insulating sheet 100-2, it is possible to suppress the algae from colliding with the glass window 10 .

In addition, as the second function providing layer 150 is applied to the other surface of the resin sheet 110 of the second heat insulating sheet 100-2, contamination of the other surface of the resin sheet 110 by external conditions is suppressed as much as possible, and contamination Even if this happens, it can be easily cleaned by simple water cleaning.

Therefore, according to the present invention, the dot-type adhesive 120 is configured on one surface of the resin sheet 110 at regular intervals, and the resin sheet 110 is formed inside or outside the glass window 10 through the dot-type adhesive 120 . Through adhesion to the dot-type adhesive 120, an air layer is provided between one surface of the resin sheet 110 and the glass window 10 by the thickness of the dot-type adhesive 120, so that visibility and thermal insulation performance can be improved.

In addition, even if a functional additive is applied to one surface of the resin sheet 110 and dew condensation occurs due to the air layer, the resin sheet 110 may have moisture absorptive and desorptive properties, anti-fungal properties and suppression of formaldehyde dissipation.

In addition, a plurality of algae-preventing patterns are printed on one or the other surface of the resin sheet 110 to prevent algae from colliding with the glass window.

In addition, a functional additive may be applied to the other surface of the resin sheet 110 so that the other surface of the resin sheet 110 has a hydrophilic and anti-contamination function.

Although the present invention described above has been described with respect to specific embodiments, various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the claims and equivalents of the claims.
