Description

Insulation material having high adhesion performance, an external insulation system using the same, and a construction method thereof {Idnsulating materials having high adhesion performance and external insulation system using that and construction method thereof}

The present invention relates to an insulating material having high adhesion performance, an external thermal insulation system using the same, and a construction method thereof, and more particularly, a high adhesive performance that can simplify the construction process in the external thermal insulation method by increasing the adhesion of the insulating material in the external thermal insulation system It relates to an insulating material having a, an external thermal insulation system using the same, and a construction method thereof.

Heat loss through windows and exterior walls accounts for the largest proportion of energy consumption in buildings. Among them, in order to prevent heat loss through the outer wall, an insulating material is generally used.

According to the location where the insulation is used, it is divided into an external insulation method and an internal insulation method. The double exterior insulation method is a method of installing insulation on the outer surface of the wall.

The external insulation method has advantages and disadvantages. The advantage is that it forms an effective insulation layer right inside the exterior material, so it is not affected by heat caused by sunlight and cold, so heat loss is small. In addition, since it can be used as a heat storage material for maintaining an indoor environment on a floor, wall, or roof, less energy is used to maintain an appropriate indoor temperature. In addition, since the building structure serves as a heat storage body for maintaining the indoor environment, it is difficult to generate an extreme temperature difference indoors, and there is little concern about dew condensation in winter.

On the other hand, when a building that is not used for a long time is maintained at a temperature using an air conditioner such as an air conditioner, it takes a long time to maintain the temperature because heat is transferred to a structure other than the internal space. In addition, since work for attaching the insulating material from the outside of the building is required, construction time is long and labor costs are high.

In this exterior insulation method, a member such as a fastener must be used to fix the insulation to the concrete exterior wall.

When the insulation material is fixed to the exterior wall using a member such as a fastener, the construction process for installing the insulation material to the exterior wall is complicated and takes a long time. In addition, heat is transferred to the outer wall through a metal member such as a fastener and has a limit in blocking thermal bridges.

Hereinafter, with reference to the accompanying drawings, a heat insulating material having a high adhesive performance according to an embodiment of the present invention, an external insulation system using the same, and a construction method thereof will be described in detail.

1 is a cross-sectional view of a heat insulating material having high adhesion performance according to an embodiment of the present invention.

Referring to FIG. 1 , the heat insulator 100 having high adhesion performance according to an embodiment of the present invention is provided with an adhesive layer 122 on one side of the heat insulator 110 and the sheet 121 centered on the heat insulating material ( 110), and the other side is provided with a flame-retardant reinforcing fiber layer 123 and includes a waterproof sheet 120 that is adhered with mortar.

As the insulating material used in the insulating material with this high adhesion performance, expanded polystyrene (EPS), extruded expanded polystyrene (XPS), vacuum insulating material, etc. may be used. Among them, since the surface of the vacuum insulation is coated with a thin aluminum plate and the surface is slippery, it is not easy to attach the vacuum insulation to the outer wall or the like.

Since the flame-retardant reinforcing fiber layer 123 is formed on the waterproof sheet 120 surrounding the insulating material such as the vacuum insulating material, the adhesion performance with the mortar layer, which will be described later, can be improved.

The waterproof sheet 120 is installed to surround the insulating material 110 . Insulation materials such as expanded polystyrene (EPS) are manufactured by the bead method, and there are many voids inside, so when moisture penetrates into the inside of expanded polystyrene (EPS), the insulation performance of expanded polystyrene (EPS) is improved. will fall However, in the present embodiment, the waterproof sheet 120 is installed to surround the insulating material 110 , thereby preventing moisture from penetrating into the insulating material 110 , thereby improving the thermal insulation performance of the insulating material 110 .

In addition, the vacuum insulation material is easy to break because the core material is surrounded by an outer shell such as an aluminum thin plate. By installing the insulation material 110 so that the waterproof sheet 120 surrounds it, the insulation 110 can be prevented from being damaged.

On the other hand, an insulating material such as expanded polystyrene (EPS: Expanded polystyrene) is generally an organic insulating material made of an organic material. Such an organic heat insulating material is weak against fire, and by wrapping the insulating material 110 with the waterproof sheet 120 , the fire resistance performance of the heat insulating material 110 can be improved.

As an example of the waterproof sheet 120 , an adhesive layer 122 may be formed on one side of the sheet 121 using butyl rubber, and a flame retardant reinforcing fiber layer 123 may be formed on the other side of the butyl rubber. At this time, the butyl rubber sheet 121 and the flame-retardant reinforcing fiber layer 123 are mixed with a flame retardant.

On the other hand, when the surface on which the adhesive layer 122 is formed of the waterproof sheet 120 is attached to the insulating material 110 , the flame retardant reinforcing fiber layer 123 is left on the other side of the waterproof sheet 120 .

The flame retardant reinforcing fiber layer 123 may be formed of a nonwoven fabric or polyethylene terephthalate (PET). Such a flame-retardant reinforcing fiber layer 123 increases the strength when bonding the insulating material 110 to the outer wall 10 with mortar so that the insulating material 110 does not easily fall off the outer wall 10 .

Nonwoven fabrics are made in a felt shape by arranging fibers in parallel or irregular directions without going through a weaving process and bonding them with a synthetic resin adhesive. In such a nonwoven fabric, since fibers are arranged in a negative direction, when the mortar is adhered to the nonwoven fabric, the adhesive force may be further strengthened.

Meanwhile, the waterproof sheet 120 may be integrally formed with the flame retardant reinforcing fiber layer 123 . When the adhesive layer 122 of the waterproof sheet 120 having the flame retardant reinforcing fiber layer 123 integrally formed as described above is attached to the heat insulating material 110, the heat insulating material 100 having high adhesive performance according to the present embodiment can be easily manufactured. can

The heat insulating material 100 with high adhesive performance manufactured as described above is adhered to the outer wall 10 using mortar. Hereinafter, an external insulation system using the heat insulating material 100 with high adhesive performance will be described.

FIG. 2 is a cross-sectional view of an external insulation system to which the heat insulating material having high adhesion performance shown in FIG. 1 is applied.

Referring to Figure 2, the external insulation system according to an embodiment of the present invention is a first mortar layer 50 attached to the outer wall 10 of the building; One side of the insulating material 110 and the sheet 121 is provided with an adhesive layer 122 and is attached to the insulating material 110, and the other side of the sheet 121 is provided with a flame-retardant reinforcing fiber layer 123 and is adhered with mortar. Insulation material 100 having a high adhesion performance having a waterproof sheet 120; a second mortar layer 150 attached to the outside of the heat insulating material 100 having a high adhesive performance; The second mortar layer 150 includes a metal exterior material 200 that is adhered to the heat insulating material 100 having high adhesion performance.

The first mortar layer 50 is a layer for attaching the insulating material to the outer wall. Since the flame-retardant reinforcing fiber layer 123 is formed on the surface of the heat insulating material 100 having high adhesion performance, mortar can be applied to the flame-retardant reinforcing fiber layer 123 and directly attached to the outer wall 10 . When the mortar is hardened, the first mortar layer 50 is formed, so that the heat insulating material 100 having high adhesion performance can be directly attached to the outer wall 10 without using hardware such as fasteners. Therefore, the work for installing the insulating material on the outer wall is simplified, so the work speed can be improved and the cost of hardware can be saved.

In addition, when using hardware such as fasteners, a heat bridge occurs through the hardware, etc., and since the insulation material can be attached to the outer wall without using any hardware, the occurrence of the thermal bridge can be prevented.

On the other hand, the second mortar layer 150 is formed on the other side of the heat insulating material 100 having a high adhesive performance. The second mortar layer 150 is a layer on which an exterior is formed.

The second mortar layer 150 may be finished by simply applying cement, but may be attached to a stone or metal exterior material.

In the case of the stone exterior material, the adhesion with the second mortar layer 150 is large, but since the stone is basically heavy, it is not easy to attach the stone exterior material using only the second mortar layer 150 . On the other hand, in the case of the metal exterior material 200, although light, the adhesion is not high because the surface is smooth.

Therefore, in general, when a metal exterior material is installed on an exterior wall, a fixing member such as a square pipe is installed on the exterior wall, and then the metal exterior material is installed on the fixing member. When the metal exterior material is constructed in this way, it takes a long time to install a fixing member such as a square pipe and a lot of expensive square pipes are used, which causes a cost increase in construction.

In the external insulation system according to this embodiment, only the second mortar layer 150 is used to attach the metal exterior material 200 to the insulation material 100 having high adhesion performance.

The pocket portion 210 has a space in which some mortar forming the second mortar layer 150 can be filled. The shape of the pocket portion 210 can be formed in various ways, as shown in FIG. 3 , a circular shape, a trapezoidal shape, a flat quadrilateral shape, etc. are formed with a narrow entrance, so that when a part of the second mortar layer 150 is filled and cured, the bonding force is increased. It is preferable to be formed in an increasing shape.

Referring to FIG. 4 , some mortar forming the second mortar layer 150 is filled with the pocket portion 210 of the metal exterior material 200 , and when the mortar filled in the pocket portion 210 is cured, the metal exterior material Reference numeral 200 is integrated with the second mortar layer 150 to prevent the metal exterior material 200 from being separated from the heat insulating material 100 having high adhesion performance.

5 is a view of a metal exterior material according to another embodiment applied to an external insulation system, and FIG. 6 is a cross-sectional view showing the appearance of the metal exterior material shown in FIG. 5 attached to the insulation material with high adhesion performance shown in FIG. .

Referring to FIG. 5 , the metal exterior material 200 according to another embodiment is partially buried in the second mortar layer 150 and includes a binding unit 220 to increase adhesion. In order to form such a fastening part 220, as shown in FIG. 5, legs spread on both sides of the metal exterior material 200 are formed on one side, or the metal exterior material 200 is punched through the bolt and fastened with a nut. Thus, a binding portion may be formed.

Referring to FIG. 6 , the binding part 220 of the metal exterior material 200 is buried in the second mortar layer 150 , and when the second mortar layer 150 is cured in this state, the binding part 220 is the second It is bound to the mortar layer 150 . Accordingly, the metal exterior material 200 is integrated with the second mortar layer 150 to prevent the metal exterior material 200 from being separated from the heat insulating material 100 having high adhesion performance.

Next, the construction method of the above-described external insulation system will be described.
