reinforced concrete structure will rapidly decrease in strength when it is more than 350 degrees Celsius heat, causing it to collapse. Recently, the research team of Professor Zhai Shuhong of China University of Science and Technology developed a phenolic resin/silicon dioxide composite aerogel material with dual network structure, which can "insulate" the high temperature of 1300 degrees Celsius to about 300 degrees Celsius, and has application prospects in improving building safety and energy conservation.published the results in the German Journal of Applied Chemistry, an international academic journal. The composite aerogel of this dual-network structure developed by the Zhai Shuhong Task Force has a branch-like micro-porous structure with fiber sizes within 20 nanometers, and the two components are each connected to a continuous network, achieving uniform dispersion of organic and unitless components on the nanoscale. This aerogel can withstand 60% compression without rupture, with good mechanical strength and processability; The two components have a strong interaction, synergy with its porous, resulting in a good thermal insulation effect, better than traditional foaming polystyrene, mineral cotton and other materials.researchers used a propane butane spray flame of 1,300 degrees Celsius to detect the fire resistance of the aerogel and used an infrared thermal imager to record temperature changes on the back of the sample. After 30 minutes of testing, the temperature on the back of the sample was stable at about 300 degrees Celsius, and with the combustion of the unit, the silicon dioxide network was exposed and attached to the aerogel surface without falling off, continuing to act as an isolated heat.it is understood that this new material excellent fire flame retardant and flame erosion resistance, can avoid the failure of the building's load structure in the event of a fire, for the evacuation of personnel to buy valuable time. In addition, the use of insulation materials can improve the energy utilization of buildings and reduce energy consumption.
