The invention belonging to a foam material field relates to a preparation method for micro-sphere compound foam materials, which is characterized in comprising the following steps: 1) steps of batch mixing, bubble exhausting and molding: according to that a hollow micro-sphere is epoxide resin with weight of 0.1 to 6 wt%, firming agent is the epoxide resin with weight of 10-15wt%, plasticiser is the epoxide resin with weight of 0-20wt% and the diluent is the epoxide resin with weight of 0-20wt%, selection; stirring and mixing to get mixed materials, then a rolling and bubble exhausting treatment is carried out to the mixed materials by a rolling machine and then resin slurry mixed evenly is obtained, then the resin slurry is poured into a module to get molded; 2) earlier low temperature solidification step: the module containing the resin slurry is put into a container with low temperature and vacuum condition for solidification for 5 to 10 hours to get high viscosity resin slurry; 3)later solidification step: at first under the condition with solidification temperature of 20 DEG C to 50 DEG C, solidification is carried out for 2 to 12 hours, then temperature is increased to 100 to 120 DEG C, and solidification is carried out for 2 to 4 hours, then the micro-sphere compound foam materials are obtained. The method has a simple preparation procedure and the micro-sphere filled is evenly distributed.
