AI Technical Summary
Existing building insulation materials cannot simultaneously achieve Class A fire resistance, high-efficiency insulation, excellent waterproofing, good breathability, and lightweight properties, resulting in problems such as fire safety hazards, poor insulation performance, and susceptibility to cracking.
The composite aerogel insulation board is composed of fast-hardening low-alkali sulfoaluminate cement, hydrophobic aerogel, glass fiber, redispersible latex powder, etc. Through a dual foaming system and a ternary polymer network, a high-porosity closed-cell structure is formed. Combined with the hydrophobic aerogel and the foamed cement matrix, a dynamic balance system of waterproofing and breathability is formed.
It achieves A1-level flame retardancy, low thermal conductivity, low volumetric water absorption, excellent water repellency, and good weather resistance, possessing long-term durability and lightweight characteristics, which aligns with the development direction of green building materials.
