Abstract

The present invention relates to a kind of manufacturing method of airgel sheet, described method comprises: step (a), prepare silica sol and surface modifier to prepare silicon dioxide precursor; Step (b), prepare gelling catalyst; Step (c), injecting the silica precursor prepared in the step (a) onto the surface of the felt to impregnate the silica precursor; and step (d), injecting the silica precursor of the step (b) The gel catalyst prepared in is injected into the surface of the felt impregnated with the silica precursor to gel the silica precursor.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2016-0019830 filed on February 19, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an apparatus and method for manufacturing an airgel sheet, and more particularly, to an apparatus and method for manufacturing an airgel sheet having excellent thermal insulation and durability and uniform thickness. Background technique [0004] In general, aerogels are currently known high porosity materials having a high porosity of about 90% to about 99% in solids. The silica precursor solution is subjected to sol-gel polymerization to prepare a gel, and then the prepared gel is dried under supercritical or atmospheric conditions to obtain an aerogel. That is, aerogels have a pore structure filled with air. [0005] Thanks to a unique pore structure in which 90 to 9...
