Abstract:The concept of super thermal insulation material originates from early the nineties of the 20th century .Preparation and in- vestigation of nanoporous super thermal insulation material is a new subject in recent years .Along with study on nanomaterial more and more at home and abroad, the study on nanoporous super thermal insulation materila is unceadsingly developing to- ward practicability and engineering .The status of research, major achievements and further developing in the research of nanop- orous super thermal insulation material were reviewed .The concept, mechanism and formation about nanoporous super thermal insulation material were introduced .A tentative idea of preparation and investigation of nanoporous super thermal insulation ma- terial compounded with Xonotlite -SiO2 -Aerogel was given .

Keywords:nanomaterial, super thermal insulation material, nanoporous, SiO2 -Aerogel, Xonotlite
