[Chemical Formula 1]

Wherein p is an integer from 1 to 3, R1 is a C13-C15 alkene containing 1 to 3 C = C bonds, and R2 is C1-C6 alkyl.

In addition to the polyurethane, the addition of the above-mentioned four kinds of additives in the above-mentioned content range showed not only an improvement in the heat insulating performance but also a special effect of preventing the dew condensation in the winter and preventing the occurrence of sexual intercourse. It is confirmed that the effect such as improvement of the heat insulating performance, prevention of the condensation phenomenon, and prevention of sexual intercourse can not be obtained when any one of them is missing or out of the stomach content range.

On the other hand, a material in which pores of uniform size are uniformly arranged in a porous material is generally referred to as a molecular sieve. Among MCM (Mobile Crystalline Material) developed by Mobiles of America, MCM-41 is a material having straight-line pores with a uniform size on a silica plate and forming a hexagonal arrangement, that is, a honeycomb-like channel. MCM-41 is known to be produced through a liquid crystal mold path according to recent studies. That is, a surfactant forms a liquid crystal structure in an aqueous solution, a silicate ion surrounds the surroundings, a hydrothermal reaction forms a conjugate of the surfactant and MCM-41, and the surfactant is sintered at a temperature of 500 to 600 After removal by treatment, MCM-41 can be obtained. At this time, if the manufacturing conditions are changed by changing the kind of the surfactant or adding other organic materials, the pore size can be changed from 1.6 to 10 nm. In the present invention, MCM-41 is most preferable because the porosity is as high as about 80 and the content of phosphoric acid can be increased accordingly.

However, the present invention is characterized not by using the porous structure itself such as MCM-41 but by using a metal-grafted porous structure by adding a metal chloride during the synthesis of the porous structure. An example of a metal grafting porous structure in the present invention is Al grafting MCM-41, which is hereinafter referred to as Al-MCM-41. The meaning of grafting of Al is the structure in which Al is interposed between silicon and oxygen during the production of the porous structure. In the case of MCM-41, a hexagonal wall having uniform channels SiO2 (silica), they have completely different chemical structures.

The present invention can be applied to the open type heat insulating curtain wall 700 including the first to third sealing materials 500 to 520 and the first to sixth heat insulating portions 650 and so on to provide airtightness, By improving performance such as car sound and windproofness, it has an effect of effectively shielding external noises with excellent sealing performance and preventing energy flow through a window, thereby reducing cooling / heating energy of a building.

It should be noted that the embodiments disclosed in the drawings are merely examples of specific examples for the purpose of understanding, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
