Abstract: The present invention discloses a high temperature resistant outer layer covering aerogel composite material with low dielectric, high heat insulation and high fireproof characteristics and preparation method thereof. The method comprises steps of: (1) mixing hydrolysis, (2) condensation and dispersion, (3) structure molding, (4) atmospheric pressure drying, (5) outer layer covering, (6) curing molding and (7) surface treatment. In this technology, a trace amount of water-dispersible high temperature resistant glue is added to the aerogel sol in the step of condensation and dispersion, which is injected into the fiber-containing preformed structure, and dried at high temperature and atmospheric to prepare aerogel preformed materials. And then, the aerogel preformed materials are wrapped by a high temperature resistant material and cured to prepare the aerogel composite material with low dielectric, high heat insulation and high fireproof properties.

Abstract: The present invention discloses an aerogel paint with smoke-free, fireproof and high heat insulation properties and preparation method thereof. The method comprises steps of: (1) mixed hydrolysis, (2) condensation and dispersion, (3) atmospheric drying, (4) high-temperature-resistant glue mixing, (5) homogenizing and dispersing. In this technology, the aerogel particles can be prepared by condensation under suspension and dispersion, and the aerogel particles have more uniform particle sizes. After being dried with hot air on an atmospheric condition, the aerogel paint is then prepared by mixing a high-temperature-resistant glue solution with the dried aerogel particles to obtain an aerogel paint being smoke-free, toxic-free, highly fire-proof and highly heat insulative. The products developed in the present invention withstand impact of high-temperature flames more than 1200° C. for a long time, and remain unpenetrated of the aluminum plate.
