AI Technical Summary

Problems solved by technology

Organic thermal insulation materials have the advantages of light weight, good processability, high density, and good thermal insulation effect, but the disadvantages are: not resistant to aging, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, construction Difficulty, high engineering cost, limited resources, and difficult to recycle
Traditional polystyrene boards and inorganic insulation boards have excellent thermal insulation effects and are widely used in China's current wall insulation material market, but they do not have safe fireproof performance, especially when they burn. Developed countries have already been limited to extremely small application fields
In recent years, fire accidents caused by large-scale use of polystyrene board insulation materials in Chinese buildings have occurred frequently, causing huge economic losses and personal casualties
