Abstract

The present invention relates to an apparatus of manufacturing an aerogel sheet. The apparatus of manufacturing the aerogel sheet includes: a plurality of fixing vessels into which a fiber sheet is inserted; and an impregnation vessels provided with an accommodation part in which the plurality of fixing vessels are stacked in multistage and a silica precursor injection part which injects a silica precursor into the accommodation part to impregnate the silica precursor into the fiber sheet inserted into each of the fixing vessels.

First claim

The invention claimed is:

1. An apparatus for manufacturing an aerogel sheet, the apparatus comprising:
a plurality of fixing vessels into which a fiber sheet is inserted; and
an impregnation vessel accommodating the plurality of fixing vessels;
wherein the impregnation vessel comprises:
an accommodation part in which the plurality of fixing vessels are stacked;
a silica precursor injection part which injects a silica precursor into the accommodation part; and
a vacuum generation part which discharges air in the accommodation part to the outside to allow the silica precursor to ascend through suction force to improve impregnation of the silica precursor into the fiber sheet.

2. The apparatus of claim 1 , wherein the accommodation part is provided as a sealed vacuum chamber, and
the silica precursor injection part is provided in plurality on a circumferential surface of the vacuum chamber in a height direction.

3. The apparatus of claim 1 , wherein each of the plurality of fixing vessels has a box shape with an upper portion opened, and a plurality of punched holes defined in a bottom surface of the fixing vessel.

4. The apparatus of claim 1 , further comprising a silica precursor supply vessel supplying the silica precursor to the silica precursor injection part.

5. The apparatus of claim 1 , further comprising a reaction vessel in which the plurality of fixing vessels withdrawn from the impregnation vessel are accommodated to be stacked vertically, and the fiber sheet inserted in each of the fixing vessels is aged, surface-modified, and dried at a high temperature.
