Laboratory Research on Composite Tunnel Fire-Retardant Coating

摘要

Through conducting a fire resistance test as well as other physical and chemical property tests, an optimized ratio of composite binder, inorganic heat insulation fillers, and forming material was determined for the manufacture of a tunnel fire-retardant coating. The manufactured coating exhibited favorable physical and chemical performances. The experimentally obtained results support that this coating has a higher fire resistance and adhesive property in comparison to the majority of existing tunnel fire coatings.
