AI Technical Summary
Existing aerogel composite insulation boards, while taking into account waterproof performance, have insufficient thermal insulation performance and suffer from problems such as low structural strength, high brittleness, poor waterproof performance, large thickness, and heavy weight, making it difficult to meet the long-term energy-saving and durability requirements of buildings.
The structure adopts an inside-out structural design, including a base layer, an interface reinforcement layer, an aerogel insulation core layer, a waterproof transition layer, and a protective surface layer. The aerogel insulation core layer incorporates zirconium-cerium co-doped silica aerogel and reinforcing fibers, which enhance structural stability through fiber bridging effect. Combined with supercritical drying technology, the aerogel is prepared to form an all-round waterproof system.
It significantly improves the thermal insulation and waterproof performance of aerogel composite waterproof insulation boards, increases tensile strength, reduces thickness and weight, extends service life, and improves construction efficiency.
