Nano aerogel material has excellent thermal insulation and hydrophobic properties,and has broad application prospects in petrochemical industry,building energy conservation and other fields.However,it is expensive and difficult to be industrialized.The composite of aerogel material and conventional thermal insulation material can effectively reduce the amount of thermal insulation material,improve thermal insulation effect and reduce heat loss.Through comparative analysis of insulation materials,binder performance testing,and preparation process research,the aerogel/conventional insulation material heterogeneous composite insulation pipe shell was prepared and industrialized.The results show that the composite insulation shell is convenient for construction,can effectively reduce heat loss,prolong service life and maximize economic benefits.
