Research progress in the application of aerogels in fire prevention and suppression
Aerogel is a new type of nanoporous lightweight solid material with excellent thermal insulation and adsorption proper-ties,which shows a wide range of application prospects in many fields of national economy.In this paper,the heat insulation mechanism and adsorption mechanism of aerogel are briefly de-scribes.Then the research progress of the application of aerogel in the field of fire prevention and fire extinguishing in recent years is reviewed from three aspects:fireproof and heat preservation mate-rials,fireproof and thermal insulation materials,and aerogel fire extinguishing agents.It also pointed out the problems of aerogel application in fire prevention and extinguishing,such as high preparation cost,large amount of organic solvent and poor me-chanical properties,etc.,and made an outlook on the future devel-opment direction of aerogel application research in fire prevention and extinguishing.
