Aiming at heat preservation and energy saving required in a plurality of occasions of industrial production and human life, the invention relates to a preparation method of a compound type heat preservation and insulation material, which includes taking inorganic fiber or inorganic fibrous composite or a vacuum insulation panel (VIP) as a heat insulation core and using glass fiber reinforced plastic or sheet metal and the like to cover the surface of the core. The heat preservation and insulation material is low water content, good in heat preservation, long in service life, convenient in use and low in cost, with the normal temperature coefficient of heat conductivity being less than 0.025W/m.k.
