Building thermal insulation materials with silica aerogels

Project Details


This project intends to develop high-efficiency thermal insulation materials, which have the characteristics of low thermal conductivity, high strength and good weather resistance. It can be widely used in buildings to achieve energy saving, carbon reduction, and energy consumption. In the project, silica aerogel will be used as the main building insulation coating to establish aerogel-enhanced product materials. Also, multiple properties (such as mechanical property analysis, hydrophilic and hydrophobic analysis, microstructure analysis, specific surface area analysis, porosity analysis, slurry dispersion and aggregation analysis, adhesive force analysis, material surface chemical micro-composition analysis, and thermal conductivity analysis) detection platform will be established to understand the relationship between structure and material properties. For example, chemical micro-composition analysis technology will be used to further understand the relationship between surface functional groups and adhesion. Finally, for the silica aerogel-enhanced insulation materials, several properties will be achieved. For example, according to SGS ASTM C518-15, the thermal conductivity K value can reach or be less than 0.12 W/mK, adhesion can reach the degree of 5B under adhesion cross-cut testers. In addition, the mechanical properties can reach 20 MPa, and the aerogel-based insulation materials can meet the requirements of government fire and flame resistance regulations.
