Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuously forming airgel panel, a manufacturing method thereof, a manufacturing apparatus, and an airgel slurry composition,

The present invention relates to a continuously formed aerogel panel, a method of manufacturing the same, an apparatus for manufacturing the same and an airgel slurry composition, and more particularly, to a continuously formed aerogel panel based on aerogels for forming a heat- A production method thereof, a production apparatus and an airgel slurry composition.

The airgel has a porosity of 90% or more, an average pore of 50 nm and a specific surface area of about 400-1000 m 2 / g, and is characterized by heat insulating property, soundproofing and shock absorption, Dielectric materials, and shock absorbers.

In general, aerogels are ultra-fine and porous low-density materials, and various applications such as catalyst carrier, thermal insulator, particle accelerator are being applied.

In particular, aerogels are used as insulating materials as described in EP-A 0 171 722 because of their extremely low thermal conductivity as a meaning of a gel containing air as a dispersant in a broad sense, and because of the specific acoustic impedance of the aerosol, Applications that are comparable to impedance means in the art are described in the literature.

In addition, aerogels are basically divided into inorganic and organic aerogels, and inorganic aerogels are all kinds of starting materials known since 1931 (SS Kistler, Nature 1931, 127, 741), SiO2, Al2O3, TiO2, ZrO2, SnO2, Li2O, CeO2 and V2O5 aerogels and mixtures thereof (HD Gesser, PC Goswami, Chem. Rev. 1989, 89, 756ff).

It is also known that organic aerogels are made from all kinds of starting materials such as melamine formaldehyde (R. W. Pekala, J. Mater, Sci. 1989, 24, 3221).

The silica aerogels have been studied for a long time and have the effect of high temperature insulation as an inorganic insulating material. However, since they become hydrophilic when they are subjected to low-temperature supercritical drying, they can be made hydrophobic by a separate surface treatment or the like, (Iler, RK: "Chemistryof Silica ", John Wiley & Sons, NY (1978).).

Research on inorganic silica aerogels has been conducted in depth in the Lawrence Livermore National Laboratory (LLNL) in the United States.

The silica airgel, which is an inorganic insulating material, has a high manufacturing cost and is disadvantageous in that water molecules are adsorbed due to the surface covered with a hydroxyl group (-OH), which may deteriorate the heat insulating effect and is fragile.

On the other hand, since conventional organic insulating materials, such as polystyrene and polyurethane foams, are subject to environmental problems using CFCs when foam molding is performed, the use of polyurethane-based airgel as a new type of insulating material Efforts to utilize have continued and already aerogels have been synthesized using polyurethanes from ICI (Imperial Chemical Industries). (Biesmans, G., Randall, D., Francais, E., Perrut, M .: J. Non -Cryst.Solids, 225, 36-40 (1998).)

These polyurethane-based aerogels are expected to be lighter and contribute to environmental protection.

The excellent characteristics of such aerogels are required to be applied to various industries such as super insulation materials for construction, high temperature insulation materials for industrial use, automobile parts, electronic parts, ship parts, cryogenic insulation LNG, VIP cores, and catalysts.
