Title:
THERMAL INSULATION MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/040966
Kind Code:
A1
Abstract:
A thermal insulation material, and a preparation method therefor and the use thereof. The thermal insulation material is a film-like material or felt-like material, and is a flexible material. The thermal insulation material comprises a three-dimensional interpenetrating network structure composed of SiO2 ceramic nanofibers having an average diameter of 200-350 nm. The preparation method of the present invention has a simple process, a short preparation period and good formability, comprises a three-dimensional interpenetrating network structure composed of ceramic fibers, has a low thermal conductivity coefficient, good mechanical properties, a light weight and good hydrophobic properties, and is expected to be applied to the aerospace field and a high-temperature humid environment, thereby achieving efficient thermal insulation.
