    Abstract：The synthesis of insulation board core material with aerogel，white carbon black，short glass fiber as raw material，through the vacuum high barrier composite film and getter and insulation core material was applied to prepare vacuum inorganic fireproof insulation materials. Through researching the stirring speed，stirring time，fiber，load size，pressure holding time，core material dryness and vacuum degree of influence on the thermal insulation material production process，the optimum production process was obtained after analysis，and the core material formability was analyzed. The influence of core material and bulk density on thermal conductivity of thermal insulation material was also analyzed.
