The invention relates to the technical field of
aerogel, and provides a super-hydrophobic flexible
aerogel heat insulation film as well as a preparation method and application thereof. The
aerogel film comprises aerogel particles subjected to hydrophobic modification treatment and an in-situ fiberized
fiber binder, the aerogel particles subjected to hydrophobic modification treatment are wound and anchored by a three-dimensional
network structure formed by the in-situ fiberized
fiber binder. The aerogel particles subjected to hydrophobic modification treatment and the
fiber binder are used as raw materials, a specific process is adopted for
processing, a fiber three-dimensional network anchored aerogel particle
composite structure is constructed, the problem of aerogel
brittleness and the process problem of uniform
fibrosis of the fiber binder are solved, and the fiber three-dimensional network anchored aerogel particle
composite structure is obtained. The preparation of the aerogel film with excellent comprehensive performance is realized.
