Heat resistant aerogel insulation composite and method for its preparation;aerogel binder composition and method for its preparation

摘要

The invention provides a heat resistant aerogel insulation composite comprising an insulation base layer comprising hydrophobic aerogel particles and an aqueous binder, and a thermally reflective top layer comprising a protective binder and an infrared reflecting agent. The invention also provides a method of preparing a heat resistant aerogel insulation composite, as well as methods of preparing an aerogel binder composition and aerogel binder compositions so prepared.
