However, since it is not easy to change the appearance of the sandwich panel itself in order to give the interior effect to the appearance of the building, after the sandwich panel is generally constructed with the building material of the building, the interior effect is increased in the appearance of the building, The exterior is finished with various metallic materials or wooden panels to protect the building.

In this case, it is common to set a reference line on the outside of a building, to install angles at a predetermined price for installing a building exterior material along a reference line, and then to sequentially fix the building exterior materials to each angle. Building exterior materials are bonded with silicone.

However, such an installation method of the external finishing material can complicate the installation work, increase the installation cost, and use silicon or the like. In the summer, due to the high temperature, silicone oil is melted and the fouling of the exterior of the building may be damaged, Because it is necessary to regularly repair the silicon, the cost of building repair increases. Even if the exterior material of the building is changed for the remodeling, it is difficult to re-construct the entire structure, which hinders the value increase of the building through remodeling.

Preferably, the silane compound represented by the general formulas (1) and (2) may be included. The silane compounds represented by the above formulas (1) and (2) can exhibit water repellency due to a small attractive force between molecules. Therefore, water repellency is further increased when the silane compound represented by the formula (1) or the silane compound represented by the formula (2) is used singly or in combination.

When the silane compound represented by the formula (1) and the silane compound represented by the formula (2) are mixed in the range of 1: 2 to 1: 4, the water repellency is most excellent. If the thickness is out of the above range, the water repellency effect is less than the above range, and when the coating layer of the building exterior material 1 is formed, the water repellency may be lowered.

The building envelope (1) of the present invention includes a water repellent coating layer, and the water repellent coating layer may contain an antimicrobial material. Even if water is removed from the building exterior material 1, it can not be completely safe from germs present in the air, so that an antibacterial substance can be contained in the water-repellent coating layer to remove all bacteria from the outside.

The antimicrobial substance can be a known substance without limitation, and in order to further improve the antimicrobial effect, it may include a natural extract.

That is, when the water-repellent coating layer is formed using silver nanoparticles, the silver nanoparticles cause an antibacterial effect. However, there is a problem that silver nanoparticles can not be used in a large amount, so that the antimicrobial effect with silver nanoparticles can be further enhanced by including a natural extract.

This produces a water repellent coating composition for the formation of the water repellent coating layer, in addition to the silver nanoparticles, when the water repellent coating composition is prepared, by including the natural extract.

When further natural extracts are included in the water-repellent coating composition, the natural extracts in general can be uniformly contained in the water-repellent coating composition in the form of a solution. On the other hand, in the case of silver nanoparticles, even if they are uniformly contained in the water-repellent coating composition, they may not be uniformly coated at the time of forming the coating layer, and some of them may not exhibit antibacterial effect. In addition, since the antimicrobial effect is exhibited in the natural extract itself, in addition to the antibacterial effect of silver nanoparticles, the overall antibacterial effect can be further enhanced.

The coating composition is preferably an antimicrobial material; Silane-based compounds; Surfactants; bookbinder; Dispersing agent; Natural extracts; And a solvent. More specifically, the antimicrobial substance refers to a silver phosphate coating of calcium phosphate obtained by supporting a silver phosphate compound on a calcium phosphate-silver complex. The calcium phosphate-silver compound may include, for example, a tricalcium phosphate-silver compound complex.

Also, the silver ion-silicate complex means a glass, that is, a composite in which the silver ions in the structure of the silicate are physically contained or bonded, and silver ions are released from the complex to exhibit an antibacterial effect.
