Description

Aluminum heat shield insulation sheet {heat protect adiabatic seat}

The present invention relates to an insulating sheet attached to an insulating object, and more specifically, to an aluminum heat insulating insulating sheet that is thin yet has excellent heat insulating and insulating capabilities.

In general, an insulation sheet covers or wraps a specific type of insulation object to minimize heat conduction between the insulation object and the external environment. It is manufactured by mixing insulation powder with rubber resin and processing it into a sheet form. Because these insulation sheets have excellent bendability, they can be easily applied to the insulation of round or curved insulation objects such as pipes.

However, since the insulation capacity of the insulation sheet is proportional to the thickness, it had to be processed thickly to realize a large insulation capacity, and in this case, the bendability was poor, making it difficult to apply to round or curved insulation objects.

Meanwhile, when constructing a building, the inside or outside of the building is finished with foam insulation for insulation. Foam insulation generally applied to buildings is made of foaming materials such as Styrofoam and requires a thickness of at least 150 mm.

However, since the foam foam material was basically thick, its bending properties were not good, and as a result, it was not easy to have a building with a round wall or to insulate the corner area, and when it was separated into several pieces and put together, there was a gap between the foam materials that were butted together. It used to happen. In this case, cold air entered and exited through the gap, causing condensation, which reduced the durability of the building.

The present invention was created to solve the above problems, and has excellent heat blocking and insulation capabilities, can be implemented thinly, and has excellent processability, so it can be used in various shapes such as round or curved pipes, boilers, plants, buildings, etc. The purpose is to provide an aluminum heat-blocking insulation sheet that can be applied to insulation objects.

In the present invention, the insulating particles 83 are composed of a hollow body 83a made of ceramic material and a urethane layer 83b surrounding the outer peripheral surface of the hollow body 83a.

Figure 1 is a diagram for explaining the cross-sectional structure of an aluminum thermal insulation sheet according to the present invention.

As shown, the aluminum thermal insulation sheet according to the present invention has a base layer 10 attached to various types of insulation objects (A) such as pipes, boilers, plants, buildings, etc., and a base layer 10. A laminated first coat layer 20, a first aluminum layer 30 laminated on the first coat layer 20 to provide reflection and insulation functions, and a first aluminum layer 30 laminated on the first aluminum layer 30 to provide impact resistance and A first PE layer 40 that provides durability, a glass sheet layer 50 that is laminated on the first PE layer 40 to provide heat resistance corresponding to high temperatures, and a glass sheet layer 50 that is laminated on the glass sheet layer 50 to provide impact resistance and durability. A second PE layer 60 that provides a second PE layer 60, a second aluminum layer 70 that is laminated on the second PE layer 60 and performs a reflective and insulating function, and a second aluminum layer 70 that is laminated on the second aluminum layer 70. It includes a second coat layer (80) that is finished so that (70) is not exposed to the outside. l These base layer 10, first coat layer 20, first aluminum layer 30, first PE layer 40, glass sheet layer 50, second PE layer 60, second aluminum layer 70 ) and the second coat layer 80 are compressed and implemented in the form of an ultra-thin film of about 0.3 mm.

The base layer 10 is a surface in close contact with the insulation object (A). The base layer 10 is made of a flexible and heat-resistant glass fiber fabric coated with silicone, and thus maintains its physical properties without being damaged by high or cold heat generated from the insulation object (A).

The first PE layer 40 provides impact resistance and durability corresponding to impacts received from the outside, and is located between the first aluminum layer 30 and the glass sheet layer 50, which will be described later.

Additionally, the second PE layer 60 prevents pieces of glass fiber constituting the glass sheet layer 50 from closing the second open cavity 71 of the second aluminum layer 70.

FIG. 2 is a view for explaining the cross-sectional structure by extracting the first coat layer of FIG. 1, and FIG. 3 is a view for explaining the structure by extracting the heat conversion particles included in the heat absorption layer of FIG. 2, and FIGS. 4a to 4a. FIG. 4D is a diagram for explaining the heat conversion operation of the heat conversion particles of FIG. 3.

As shown, the first coat layer 20 serves as a medium to combine the base layer 10 with the first aluminum layer 30, and at the same time converts infrared energy into kinetic energy and absorbs it. This first coat layer 20 is implemented by mixing a plurality of heat conversion particles 22 with acrylic emulsion resin 21.

Acrylic emulsion resin (21) is a copolymer of acrylic acid, methacrylic acid, and styrene, and is formed by mixing the copolymer with a surfactant. It has transparency better than glass, is lightweight, has excellent processability, and has impact resistance that does not break from external impacts.

The heat conversion particles 22 are composed of a working hollow body 22a made of a polymer material made of thermoplastic resin, and a capsule 22b made of titanium dioxide, which is detachably wrapped around the outer peripheral surface of the working hollow body 22a, It has a particle size of 30~60㎛.

The heat conversion particles 22 convert the energy of infrared rays into kinetic energy and absorb it through the interaction between the working hollow body 22a and the capsule 22b. This is explained in detail as follows.

When solar infrared rays are irradiated to the heat conversion particles 22, as shown in FIG. 4A, the working hollow body 22a made of a polymer material expands due to the infrared rays irradiated from the insulation object A, but the outer circumferential surface is expanded. Since the capsule 22b is made of titanium dioxide, an inorganic material, it hardly expands, so expansion stress is generated in the working hollow body 22a. Afterwards, when the working hollow body 22a is heated by continuously irradiated infrared rays, the working hollow body 22a is partially deformed to be convex inward due to expansion stress, as shown in FIG. 4B. Afterwards, when infrared rays are continuously irradiated, the expansion force to expand the compressed air is added to the reaction force to return the working hollow body 22a made of polymer material to its original form, so that it has a convex shape inward, as shown in FIG. 4C. The deformed part instantly returns to its original shape and an impact is applied to the capsule 22b. This impact causes the capsule 22b made of titanium dioxide to instantaneously generate electrical energy, and the generated electrical energy is converted into heat and then absorbed into the heat conversion particles 22. That is, through this series of processes, the energy of solar infrared rays is converted into kinetic energy and then converted into electrical energy and then extinguished. In this process, the electrical energy is converted into heat energy and absorbed into the heat conversion particles 22. And, as shown in FIG. 4D, the working hollow body 22a, which has returned to its original shape, repeats deformation and restoration while being heated again, converting the infrared energy into electrical energy and heat energy, and then absorbing it into the heat conversion particles 22. The process is repeated. That is, the first coat layer 20 prevents heat (infrared rays) generated from the insulation object (A), such as a pipe through which a heat medium flows, a boiler, or a plant, from escaping to the outside.

Figure 5 is a diagram for explaining that the first and second open hollows formed in the first and second aluminum layers of Figure 1 absorb infrared rays.

As shown, the first aluminum layer 30 performs reflective and insulating functions and is made of high-purity aluminum with a thickness of 40 to 60 μm, and in this embodiment, 50 μm. The first aluminum layer 30 has a plurality of first open hollows 31 formed on the surface facing the insulation object (A) and the first coat layer 20, and a plurality of first closed hollows 32 formed on the inside. ) and a first reflective surface (33) formed on the opposite side of the first open hollow (31).

The first open hollow (31) has a first hollow inlet (31a) opened toward the insulation object (A) and the first coat layer (20), and the inner diameter of the first open hollow (31) is 10 to 50 micrometers. (㎛), and the inner diameter of the first hollow inlet (31a) is 1 to 3 micrometers. Due to this first open hollow 31, the heat (infrared rays (R)) generated from the insulation object (A) and passing through the first coat layer 20 is incident on the first hollow inlet 31a and then the first It is repeatedly reflected inside the open hollow 31 and absorbed into the first aluminum layer 30. That is, the first open hollow 31 causes the first aluminum layer 30 to absorb heat energy by repeatedly reflecting infrared rays incident on the first hollow inlet 31a.

The first closed hollow 32 forms an empty sphere-shaped space and provides insulation to prevent conductive heat from passing through the first aluminum layer 30.

The first reflective surface 33 is located on the opposite side of the insulation object A, that is, on the side facing the external environment. Therefore, the first reflective surface 33 performs a heat shielding function by reflecting solar infrared rays irradiated from the outside to the outside.

In this way, the first aluminum layer 30 is. The first aluminum layer 30 includes a plurality of open hollows 31 formed on the surface facing the insulation object A, closed hollows 32 formed on the inside, and a first reflecting surface 33 facing the external environment. Despite its very thin thickness of 40-60㎛, it can perform an insulation function by absorbing heat energy conducted from the insulation object (A) and a heat shield function by blocking solar infrared rays irradiated from the external environment.

The second aluminum layer 70 performs reflective and insulating functions and is made of high-purity aluminum with a thickness of 40 to 60 ㎛, in this embodiment, 50 ㎛. The second aluminum layer 70 includes a plurality of second open hollows 71 formed on the surface facing the insulation object (A) and the glass sheet layer 50, and a plurality of second closed hollow cavities 72 formed on the inside. and a second reflective surface (73) formed on the opposite side of the second open hollow (71).

The second open hollow 71 has a second hollow inlet 71a opened through the insulation object A and the glass sheet layer 50, and the inner diameter of the second open hollow 71 is 10 to 50 micrometers ( ㎛), and the second hollow inlet (71a) has an inner diameter of 1 to 3 micrometers. Due to this second open hollow 71, heat (infrared rays (R)) generated from the insulation object (A) and passing through the glass sheet layer 50 is incident on the second hollow inlet 71a and then opened to the second open hollow. It is repeatedly reflected inside the hollow 71 and absorbed into the second aluminum layer 70. That is, the second open hollow 71 causes the second aluminum layer 70 to absorb heat energy by repeatedly reflecting infrared rays incident on the second hollow inlet 71a.

The second closed hollow 72 forms an empty sphere-shaped space and provides insulation to prevent conducted heat from passing through the first aluminum layer 30.

The second reflective surface 73 is located on the opposite side of the insulation object A, that is, on the side facing the external environment. Therefore, the second reflective surface 73 performs a heat shielding function by reflecting solar infrared rays irradiated from the outside to the outside.

In this way, the second aluminum layer 70 is. The first aluminum layer 30 includes a plurality of open hollows 31 formed on the surface facing the insulation object A, a closed hollow 32 formed on the inside, and a second reflecting surface 33 facing the external environment. Despite its very thin thickness of 40-60㎛, it can perform an insulation function by absorbing heat energy conducted from the insulation object (A) and a heat shield function by blocking solar infrared rays irradiated from the external environment.

Figure 6 is a view to explain that the second coat layer of Figure 1 has a cross-sectional structure of the laminated finish insulation layer and anti-fouling layer, and Figure 7 is a diagram illustrating the structure by extracting the insulation particles included in the finish insulation layer of Figure 6. FIG. 8 is an enlarged view of the antifouling layer of FIG. 6, and FIG. 9 is a drawing explaining the structure of the antifouling particles of FIG. 8.

As shown, the heat conducted from the insulation object (A) is prevented from escaping to the external environment or the external heat is not conducted to the insulation object (A), and the second aluminum layer 70 is not exposed to the outside. It includes a finishing insulation layer 81 that prevents the surface of the finishing insulation layer 81 from being contaminated by contaminants, and an antifouling layer 85 that prevents the surface of the finishing insulation layer 81 from being contaminated by contaminants.

The finishing insulation layer 81 is implemented by mixing a plurality of insulation particles 83 with transparent acrylic emulsion resin 82, and has a thickness of 30 to 60㎛.

The insulating particles 83 are composed of a hollow body 83a made of ceramic material and a urethane layer 83b surrounding the outer peripheral surface of the hollow body 83a, and have a particle size of 5 to 10 μm.

The hollow body 83a has thermal insulation properties as it is made of a ceramic material with fine pores, and furthermore, it has even more excellent thermal insulation properties by having a hollow space inside.

The urethane layer (83b) prevents the pores from being clogged by preventing the hollow body (83a) made of ceramic material with countless pores from being in direct contact with the acrylic emulsion resin (82), and also prevents the hollow body (83a) from being clogged within the acrylic emulsion resin. Make sure it is evenly distributed.

In this way, the finishing insulation layer 81 is implemented by dispersing and mixing the insulation particles 83 made of the hollow body 83a and the urethane layer 83b in the transparent acrylic emulsion resin 82, so it has a thickness of about 30 to 60㎛. Despite this, it has excellent insulation properties.

The antifouling layer 85 is formed on the surface of the finishing insulation layer 81 to prevent contaminants from adhering to the finishing insulation layer 81, and is composed of a plurality of antifouling particles 85a.

The density of the antifouling particles 85a is smaller than the density of the acrylic emulsion resin 82. Therefore, the antifouling particles (85a) exist in a dispersed state within the acrylic emulsion resin when the acrylic emulsion resin is in a liquid state, and then form the upper insulating layer (81) as the acrylic emulsion resin (82) gradually hardens. It completely floats to the side to form an antifouling layer (85).

The antifouling particle 85a has a pin shape with sharp ends and a convex center, a length (L) of 10 to 100 nm (nanometers), and the most convex inner diameter (D) is 1/10 of the length (L). It has a size within ~2/10.

Since the antifouling particles 85a have the shape of long pins and are not bonded to the acrylic emulsion resin 82, on the surface of the liquid acrylic emulsion resin, numerous antifouling particles 85a are in close contact with each other and stand vertically by their own weight. , a portion of the erected antifouling particles 85a is fixed to the surface of the solidified acrylic emulsion resin 82. Then, the antifouling particles 85a that are not fixed to the surface of the acrylic emulsion resin 82 are separated, and eventually, the numerous antifouling particles 85a fixed to the acrylic emulsion resin 82 form numerous nanoscale protrusions. This protrusion structure maximizes the surface tension of rainwater to prevent it from adhering to the second coat layer 80, and minimizes the contact area with contaminants to prevent it from adhering and easily detaching.

As such, according to the present invention, since it is implemented in the form of an ultra-thin film of about 0.3 mm, cutting and gluing are easy, so construction is simple. Accordingly, it is easy to insulate objects of complex and various shapes such as pipes, boilers, plants, and buildings. It can be easily applied.

In addition, it can effectively prevent condensation due to its high heat reflection ability and excellent thermal insulation properties.

In addition, it is easy to construct and finish, has semi-permanent durability, can reduce damage to the exterior even if stepped on during maintenance, and has excellent acid resistance, alkali resistance, and weather resistance.

And since it is recyclable, it is environmentally friendly as there is almost no industrial waste generated during the processing or disposal of existing interior materials or tin exterior materials.

The present invention has been described with reference to an embodiment shown in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom.
