BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a surface-

A surface material of a building insulation material, and a building insulation material.

By adhering the insulation to the wall of the building, it is possible to prevent the heat from moving, so that the influence of the external temperature change on the internal temperature of the building can be reduced and the room temperature can be maintained with less energy. Among these thermal insulating materials, there is a problem that structural members such as a surface material of a heat insulating material and a wall made of a concrete or a mortar material do not adhere to each other and a gap is widened in the thermal insulating material used for attaching to a wall made of concrete or mortar.

Accordingly, when a surface material is formed only of a material appropriately adhering to a wall made of concrete or mortar, adhesiveness between the surface material and the foamed material of the heat insulating material may be deteriorated. As a result, a gap is formed between the surface material and the foamed material, There is a problem that the heat insulation performance may be remarkably deteriorated due to the deformation, dropout, and condensation of the resin.

The building insulation may be applied such that the second outer layer adheres to the thermosetting foam to form the building insulation and the first outer layer adheres to a wall comprising concrete or mortar.

The intermediate layer may have a single-layer structure or a multi-layer structure.

The multi-layer structure may be a multi-layer structure including a multi-layered glass fiber layer or a multi-layered aluminum layer, or a multi-layer structure including a structure in which a glass fiber layer and an aluminum layer are laminated.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

In the drawings, the thickness is enlarged to clearly represent the layers and regions. In the drawings, for the convenience of explanation, the thicknesses of some layers and regions are exaggerated.

Hereinafter, the formation of any structure in the "upper (or lower)" or the "upper (or lower)" of the substrate means that any structure is formed in contact with the upper surface (or lower surface) of the substrate However, the present invention is not limited to not including other configurations between the substrate and any structure formed on (or under) the substrate.

In one embodiment of the present invention, a first outer layer comprising at least one selected from the group consisting of a thermoplastics layer, a nonwoven fabric, a woven fabric, a kraft paper, and combinations thereof; An intermediate layer comprising a glass fiber layer, an aluminum layer or both; And a second outer layer including a kraft paper. The present invention also provides a surface material for a building heat insulating material.

Generally, the surface material of the heat insulating material for construction is formed of a single layer of a glass fiber layer or a nonwoven fabric layer, or a multilayer including both of them. Such glass fibers and nonwoven fabric have a low adhesion strength to the thermosetting foam to which the surface material of the heat insulating material is adhered, so that gaps are generated between the surface material of the heat insulating material and the thermosetting foam and the permeation rate of water is increased thereby the thermosetting foam is easily deformed, Resulting in deterioration of heat insulation and durability.

In addition, when the glass fiber layer is formed of a surface attached to a wall including concrete or mortar when a building is constructed, there is a problem in that it is difficult to construct because the glass fiber is scattered in the air during the construction process.

Accordingly, in the surface material of the heat insulating material for building according to an embodiment of the present invention, the second outer layer, which is a layer adhering to the thermosetting foam included in the heat insulating material, includes kraft paper, Wherein the first outer layer, which is a layer to be adhered to the first outer layer, comprises at least one selected from the group consisting of a thermoplastics layer, a nonwoven fabric, a woven fabric, a kraft paper, and combinations thereof, Excellent adhesion can be achieved for all.

Accordingly, it is possible to prevent the occurrence of gaps on the adhering surfaces thereof, thereby remarkably lowering the moisture permeability, thereby reducing the occurrence of deformation, detachment and condensation of the thermoplastic foam, thereby realizing excellent durability for a long period of time. In addition, the glass fibers and the like are not scattered in the air during the construction, and the construction is further facilitated, thereby further saving time and effort.

The thickness of the second outer layer 130 may be about 5 탆 to about 1000 탆.

Experimental Example

The heat insulating materials for building were manufactured by attaching the surface materials of the heat insulating materials for building of Examples 1 to 5 and the comparative examples 1 to 3 and the polyurethane foams, and the properties of the heat insulating materials for construction were evaluated as described below in Table 1.

(Bond strength)

Measuring method: Each of the above-mentioned insulating materials for construction was prepared as a sample of 200 X 200 X 70 mm and measured using an adhesion strength tester UTM (Instron, UTM). The adhesion strength was measured for each of the polyurethane-based foam and concrete.

Specifically, a 2 mm thick adhesive was coated on a test base plate having a thickness of 200 x 200 x 20 mm, and then measured using the adhesion strength tester.

(Water absorption rate)

Measurement method: Water absorption rate was measured according to KS M ISO 2896.

Specifically, each of the building-use insulating materials was prepared as a sample of 150 X 150 x 70 mm, each sample was dried at 25 ° C for 24 hours, and the weight of the sample was measured. Then, the sample was immersed in normal temperature water, After allowing to stand for 96 hours in a room temperature chamber, the sample was taken out and the moisture absorption rate was measured by measuring the weight of the moisture-absorbed sample.

(Flame retardancy)

Measuring method: According to KS F ISO 5660-1, the flammability was evaluated by measuring the total heat emission using a cone calorimeter (FESTEC, cone calorimeter). The smaller the total heat emission value, the more the flammability increased.

Specifically, each of the above-mentioned building heat insulating materials was prepared as a sample having a size of 100 x 100 x 50 mm, and the surface contacting the opposite side of the concrete adhesion surface was subjected to the same conditions and the same method three times, and the average value thereof was measured as total heat radiation amount.

Bond strength (g) Water Absorption Rate (%) Total Heat Emissions (MJ) concrete
Bond strength (N / m ² ) Example 1 250 2.5 10.3 4232 Example 2 270 3.2 15.6 4378 Example 3 260 2.3 6.4 4261 Example 4 260 3.9 17.2 3714 Example 5 280 5.7 20.7 4219 Comparative Example 1 260 4.9 21.5 4437 Comparative Example 2 200 5.5 22.6 3445 Comparative Example 3 80 6.1 20.1 3159

In the case of Examples 1-5, it was confirmed that the adhesion strength was excellent for both the polyurethane foam and the concrete, and the water absorption rate and the total heat emission amount were also low. Particularly, in Examples 1 and 3, it can be clearly expected that the adhesive strength is further improved, the water absorption rate and the total heat emission amount are also lower, thereby realizing excellent durability and flame retardancy.

On the other hand, in Comparative Example 1, although the bonding strength is good, the water absorption rate and the total heat emission amount are high.

In addition, in Comparative Example 2, the adhesion strength to the thermosetting foam was so low that the gap between the surface material of the thermal insulation material and the thermosetting foam easily formed and the durability was inferior and the moisture easily penetrated into the gap, so that the thermosetting foam deformed, Can easily occur.

In addition, in Comparative Example 3, the adhesion strength was significantly lowered, and not only between the surface material of the thermal insulation material and the polyurethane foam, but also the gap between the surface material of the thermal insulation material and the concrete was easily generated and the durability was remarkably decreased. It can be clearly expected that a comfortable indoor environment can not be created.
