Production method for aerogel laminate, and aerogel laminate roll
The present invention relates to a production method for an aerogel laminate including a support, and an aerogel layer disposed on the support and having a thickness of 200 μm or less, the method comprising a step of washing a wet gel laminate including the support and a wet gel layer disposed on the support by a roll-to-roll scheme.
1. A production method for an aerogel laminate comprising a support, and an aerogel layer disposed on the support, the aerogel layer being a layer containing an aerogel having a structure derived from polysiloxane and having a thickness of 10 μm to 200 μm, the method comprising:
a step of washing a wet gel laminate comprising the support and a wet gel layer disposed on the support by a roll-to-roll scheme.
2. The production method for an aerogel laminate according to claim 1 , wherein a thickness of the wet gel layer is 400 μm or less.
3. The production method for an aerogel laminate according to claim 1 , wherein the wet gel contains a gel formed from a sol containing at least one selected from the group consisting of polysiloxane compounds having a reactive group in the molecule and hydrolysis products of the polysiloxane compounds.
4. The production method for an aerogel laminate according to claim 1 , wherein the wet gel layer contains a gel formed from a sol containing silica particles.
5. The production method for an aerogel laminate according to claim 1 , wherein the wet gel laminate is washed using a hydrophilic organic solvent.
