Title:
HIGH-TEMPERATURE-RESISTANT SMOKE-PREVENTION AIR-EXHAUSTING PIPE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/201688
Kind Code:
A1
Abstract:
The present invention relates to the technical field of firefighting and smoke exhaust and provides a technical solution. By modifying and optimizing a silicon dioxide aerogel, the internal structure of a silicon dioxide aerogel material is improved, and an aluminum oxide/aluminum salt material with better fire resistance and slightly poor heat insulation performance is combined with the silicon dioxide aerogel, so as to form composite silicon dioxide aerogel particles, in which the shell is the aluminum oxide/aluminum salt and the inner core is the silicon dioxide aerogel, or composite silicon dioxide aerogel particles, in which the shell is the silicon dioxide aerogel and the inner core is the aluminum oxide/aluminum salt. In such a way, the silicon dioxide aerogel is kept stable under a high-temperature condition; in addition, the composite particles have a relatively good heat insulation performance, and can further maintain relatively good physical and chemical performances and can meet the use requirements of a smoke-prevention air-exhausting pipeline during the application thereof to a heat insulation layer.
