Description

Heat insulating inside material of building

The present invention relates to a building insulation interior material, and more specifically, to the construction of the interior, such as the ceiling, walls, floors of the building, the building insulation insulation material made of a multi-layer structure so as to prevent the mutual exchange of heat between indoor and outdoor to the maximum. The present invention relates to a building insulation insulation material for coating copper powder on one side thereof and coating the same to maximize insulation even though the thickness is light.

As is well known, the largest portion of the energy consumption of buildings is heat loss through the skin. Therefore, for the energy saving in buildings, proper insulation design and construction of interior and exterior materials are prioritized.

However, buildings without proper insulation design and construction can maintain proper room temperature only by providing energy constantly, resulting in large energy loss and inefficiency.

In Korea, styrofoam, urethane foam, glass wool, rock wool, PE foam, etc. are mainly used to insulate, and resistance-type insulation methods that minimize heat exchange by conduction and convection have been mainly used.

Polystyrene foam, which is the most in demand as a conventional heat insulator, has the advantage of being easy to process and light because the air is made up of more than 98% of the volume, but has a low heat resistance temperature and a plate-like shape compared to other heat insulators. Hazardous gases are generated and chemical reactions have weaknesses, which easily invade organic solvents of aromatic hydrocarbons.

In addition, inorganic insulating materials such as glass wool and rock wool are strong in heat and have excellent workability at joints, but have high hygroscopicity and poor mechanical properties in the molded state. Care must be taken to avoid inhalation or contact with dust from the insulation.

Looking at the heat insulating material used in the interior and exterior materials of the conventional building, the plate-shaped Styrofoam insulation, gypsum board or paper-based honeycomb is attached to one side of the Styrofoam, but these insulation materials are light, easy to handle and insulated, but it is a plate-like It is made of a heat insulating material of the roll type not only can not be loaded and stored, but also does not have an air bubble there is a disadvantage that does not relieve the internal and external impact. In addition, in the case of the insulation without air bubble, there is a heat insulation effect to some extent, but there is a problem that it is not efficient enough to block the movement of air and block the movement of air by forming an air layer.

In addition, since the heat insulating material is made of a plate shape and rolled up, the volume increases, which requires a lot of logistical cost during transport and loading. All.

In addition, in the case of the previously registered reflective insulating material for building interior and exterior walls, a polyester nonwoven fabric layer and a polyethylene foam layer are adhered to an inner surface of each of an aluminum foil layer coated with a polyolefin resin on the surface thereof and the polyester Although the reflective insulation for interior and exterior walls made by adhering an air bubble layer between a nonwoven fabric layer and a polyethylene foam layer has been proposed, this is a result of attaching the air bubble layer and polyethylene foam in succession to the reflective insulation material. There was a problem that the volume is large, the heat insulation effect is low compared to the volume, the aluminum foil is exposed to the outside, and the polyester nonwoven layer is laminated inside the aluminum foil, it was unable to perform the function of moisture absorption and moisture-proof of the polyester nonwoven layer, There was a problem that the thin aluminum foil is easily damaged from various external factors.

The present invention is applied to one surface of a building insulation insulation material made of a multi-layered structure to prevent the mutual exchange of heat between indoor and outdoor by building with interior materials such as ceiling, wall, floor of the building to the maximum and coating the thickness In spite of its light weight, it is possible to maximize insulation, and it is easy to store and transport, and impregnates ocher particles and charcoal particles in the nonwoven fabric formed by span-bonding long fibers, so that the insulation, insulation and antibacterial and deodorizing effect can be expected. Its purpose is to provide thermal insulation interiors for construction.

The present invention for solving the conventional problems as described above is constructed with a multi-layered structure so as to maximize the thermal insulation by maximally blocking the heat exchange between the interior and exterior by building with interior materials, such as ceiling, wall, floor of the building In the interior material, a long-fiber nonwoven fabric formed by spun-bonding filament yarn of polyester material, the aluminum reflective sheet which is adhered to the lower end of the long-fiber nonwoven fabric to reflect internal heat A foamed synthetic resin formed by foaming a synthetic resin to block heat exchange between the interior and the outside by being thermally fused to the bottom of the aluminum reflective sheet, and an aluminum reflective sheet provided to reflect external heat by being thermally fused to the bottom of the foamed synthetic resin; Copper powder, which is applied to the lower end of the aluminum reflective sheet to improve the thermal insulation In order to fix the copper powder to the aluminum reflecting sheet at the bottom provides a building insulation insulation consisting of a transparent coating made by applying a polyester (polyester).

According to the insulation insulation material for building construction of the present invention, by applying the interior material such as ceiling, wall, floor of the building to apply the copper powder to one surface of the building insulation insulation material made of a multi-layer structure so as to prevent the mutual exchange of heat between indoor and outdoor to the maximum And by coating it, it can maximize insulation even though it is light in thickness. It is easy to store and transport, and impregnates ocher particles and charcoal particles in the nonwoven fabric made by span-bonding long fibers to improve insulation, insulation, and antibacterial and odor. It is a very useful invention that can be expected to be effective.

Hereinafter, the configuration and operation of the insulation interior material for building construction of the present invention according to the accompanying drawings in more detail.

First, Figure 1 is a perspective view showing a heat insulating interior material for building construction of the present invention, Figure 2a is a cross-sectional view showing a heat insulating interior material for building construction of the present invention, Figure 2b is a cross-sectional view showing another embodiment of the thermal insulation interior material for building construction of the present invention, Figure 3 is a long fiber A schematic diagram illustrating the impregnation process of a nonwoven fabric.

The building insulation thermal insulation material 10 of the present invention as shown in Figure 1 is a long-fiber non-woven fabric (100) made by spun-bonding filament yarn of polyester (polyester) material;

An aluminum reflection sheet 200 attached to a lower end of the long fiber nonwoven fabric 100 to reflect internal heat;

Foamed synthetic resin (300) formed by foaming the synthetic resin to heat-sealed at the bottom of the aluminum reflecting sheet 200 to block heat exchange in the room and outside;

Aluminum reflective sheet 400 which is thermally fused to the lower end of the foamed synthetic resin 300 so as to reflect the external heat;

Copper powder 500 is applied to the lower end of the aluminum reflective sheet 400 to improve the thermal insulation;

It consists of a transparent coating layer 600 formed by applying a polyester resin (polyester) in order to fix the copper powder 500 to the aluminum reflective sheet 400 at the bottom of the copper powder (500).

The long fiber nonwoven fabric 100 is formed by spunbond molding a filament yarn of polyester material, and a spunbond nonwoven fabric is mainly used as an industrial material or a civil engineering material. It is widely used because of its excellent strength, durability and low price.

Spun-bond (spun-bond) is one of the nonwoven fabric forming method, and means a long fiber nonwoven fabric because it uses a long fiber filament. The process is classified into spinning process, stretching process, carding process, and collecting process. The filament is discharged from the extruder, the released filament is stretched to improve the tensile strength, and the spun and stretched filaments are uniformly separated and opened. This is accomplished by depositing and collecting them on a conveyor or the like.

Since the long fiber nonwoven fabric 100 as described above is harmless to the human body because it is excellent in heat resistance, cold resistance, chemical resistance, and weather resistance, it is easy to use on a wallpaper construction surface, and has good shape safety, breathability, and sound insulation. In addition, moisture absorption of the wallpaper can be expected to be able to expect the humidity control ability, it gives an elasticity to the wall to act as a cushion action according to this can also be expected.

Aluminum reflective sheet 200 is bonded to the bottom of the long fiber nonwoven fabric 100 is configured to reflect the heat inside, the aluminum reflective sheet 200 and the long fiber nonwoven fabric 100 is coated with an adhesive And the adhesive layer 20 is formed so as not to damage the long fiber nonwoven fabric 100 is attached. The long fiber nonwoven fabric 100 is made of a thin filament yarn, so it may be damaged when heat is applied. Therefore, it is preferable to apply an adhesive, dry it at room temperature, and adhere it by a dry method. Of course, the adhesive layer 20 can be formed using a T-die method.

 In general, it is well known that aluminum can be expected to have a reflective heat insulating effect due to its excellent heat reflecting ability, excellent radiant heat treatment ability, and soundproofing and surface strengthening effect.

In particular, the reflective heat insulating effect is the most excellent, the reflective heat insulating material is a material having a low emissivity against heat radiation refers to the case of heat insulation by reflecting radiant thermal energy.

Heat transfer by radiation can be suppressed by the use of a surface with less absorption and radiation of radiant heat. These surfaces not only look shiny, but also reflect the radiant heat of electromagnetic waves that behave like light.

The heat insulating material of this type is, for example, aluminum, the aluminum reflecting sheet 200 is formed of a very thin aluminum, because its thickness is very thin, the influence of heat conduction by it will be negligible.

Reflective insulation that uses heat reflection on the material surface is usually used in metal sheets with good reflectivity, which include aluminum blankets, blankets with metal sheets, gypsum boards with aluminum sheets, and special Alloy, coated iron plate heat reflecting insulation, heat reflecting coating and the like.

Foamed synthetic resin 300 is formed by foaming the synthetic resin to heat-sealed at the bottom of the aluminum reflective sheet 200 to block heat exchange inside and outside, excellent buffering and restoring power, good flexibility and repeated impact Maintaining its original shape without breaking, strong compressive strength, excellent chemical resistance, chemical stability, long-term storage, excellent oil resistance, heat resistance, cold resistance, durability, moisture does not pass, heat insulation does not decrease, and thermal conductivity This low heat and condensation prevention effect is excellent, and also acts as a sound absorbing material, it also serves to block the movement of noise between walls and also to mitigate external shocks.

For reference, the foam molding of the synthetic resin can be extruded by mixing the resin, the foaming agent and other additives in advance, or by injecting the foaming agent at a suitable position of the extruder and dispersing it uniformly under high pressure, and then extruding the extrudate through the die. When the foam is compressed, it immediately expands to foam.

In another method, the extrusion process is a method of extruding at a low temperature at which the blowing agent is not decomposed and foaming while passing through the heating apparatus again. The blowing agent is impregnated into polymer pellets, chips, beads, or the like and injected into the particles, and then foamed in a similar manner to the production of popcorn in secondary processing, followed by molding. In some cases, the blowing agent, resin, and other additives may be mixed into a mold and foamed to form a polymer block in an appropriate form.

In the case of polymers made of simple condensation polymerization of polyurethanes, urea resins, silicone resins, etc., low-molecular substances produced during condensation may be rapidly generated and foams may be manufactured using them as foaming agents. In some cases, resin polymerization occurs and foaming occurs at the same time.

Aluminum reflective sheet 400 is a heat-sealed composition at the lower end of the foamed synthetic resin 300 is configured to reflect the heat of the outside, in addition to the aluminum reflective sheet 200 described above, excellent heat reflection ability of the reflective type Insulation effect can be expected, excellent radiant heat treatment ability, soundproofing, surface strengthening action.

As described above, when the aluminum reflective sheets 200 and 400 are attached to the upper and lower ends of the foamed synthetic resin 300, respectively, by heat fusion, the interior and exterior heat is effectively reflected from both sides of the foamed synthetic resin 300 to exchange heat. It is possible to reliably block the phenomenon, thereby improving the thermal insulation effect of the thermal insulation interior material 10 for building the present invention.

Copper powder 500 is configured to be applied to the lower end of the aluminum reflective sheet 400 to improve the thermal insulation, the lower portion of the copper powder 500 is transparent to fix the copper powder 500 and the aluminum reflective sheet 400 to each other Polyester coating (polyester) is applied to form a coating layer (600).

Copper powder 500 means copper powder, which is provided at the lower end of the aluminum reflective sheet 400 to further improve the thermal insulation effect of the heat insulating interior material 10 for construction of the present invention together with the aluminum reflective sheet 400, and radiant heat treatment The excellent heat reflection effect can be expected than when only the aluminum reflective sheet 400 is provided with excellent ability.

Above all, the copper powder 500 is a fine particle, provided with a thin layer at the bottom of the aluminum reflective sheet 400, but despite the light weight, the reflection effect is very improved, so that the construction and storage of the thermal insulation interior material 10 for construction is easy. Not only is it economical.

In order to fix the copper powder 500 and the aluminum reflective sheet 400 to the lower end of the copper powder 500, a transparent polyester resin is coated to form a coating layer 600, and a polyester resin The coating layer 600 may be formed by covering and heating the copper powder 500 with a film paper, or by applying a liquid polyester resin and drying and curing the coating layer 600.

In addition, the aluminum reflection sheet (200, 400) and the foamed synthetic resin 300 is coated with a polyethylene resin (polyethylene) and heated therebetween to form a heat-sealed layer 700, aluminum reflective sheets (200, 400) and The foamed synthetic resin 300 is to be attached.

The aluminum reflective sheets 200 and 400 and the foamed synthetic resin 300 may be thermally fused only to themselves, that is, the foamed synthetic resin 300 may be melted and thermally fused to the aluminum reflective sheets 200 and 400 at the same time. In order to provide, it is also possible to bond using a T-die method of dissolving, applying and compression-cooling polyethylene-based resin, between the aluminum reflective sheet (200, 400) and the foamed synthetic resin (300) As the polyethylene resin (polyethylene) is applied and heated to form the heat sealing layer 700, the aluminum reflective sheets 200 and 400 and the foamed synthetic resin 300 may be more firmly fixed.
