Researchers from the University of Science and Technology of China have developed a new composite construction material that is fire-retardant and can resist about 1,300 degrees Celsius flame without disintegration. The composite is synthesized from phenol-formaldehyde-resin and silica and can resist a high-temperature flame without disintegration. The research results were published in a German academic journal, Angewandte Chemie.
According to the researchers, the composite is highly porous and resilient with low thermal conductivity. Material can be used in old as well as under construction buildings. By using it in walls, they can be protected against fire-induced collapse of reinforced concrete structures. This can provide more time to evacuate the occupants of the building in case of fire. According to the researchers the new composite material provides better fire-resistance than current insulation materials such as expanded polystyrene and glass wool.
The research team was led by Prof. Yu Shuhong.
