18k gold dog tags
HEFEI ¡ª Researchers from the University of Science and Technology of China have developed a new fire-retardant construction material that can resist about 1,300 degrees Celsius flame without disintegration.
A research team led by Prof Yu Shuhong have come up with a composite aerogel with low thermal conductivity and excellent fire resistance.
The composite, synthesized from phenol18k gold dog tags-formaldehyde-resin and silica, can resist a high-temperature flame without disintegration, said researcher Yu Zhilong.
The composite is highly porous and resilient. It displays better fire-resistance than current insulation materials such as expanded polystyrene and glass wool.
According to researchers, if used in walls, the material could provide extended protection against fire-induced collapse of reinforced concrete structures, winning more time for evacuation of the building.
It can also b[MG_SEO]e used to insulate older buildings.
The research results were published in Angewandte Chemie, a German academic journal.
