The invention belongs to the technical field of composite materials, and particularly relates to a
metal-based
polymer material preparation method. The method comprises the following steps of adding
epoxy resin into a reaction kettle, heating and uniformly dispersing, adding 5-10 parts of modified
epoxy resin, adding an
epoxy diluent and a dispersing agent, adding an anti-
settling aid, adding a
polymerization aid, adding a defoaming agent, mixing Ti,
iron oxide powder,
electrolytic iron powder, reduced
iron powder,
carbon black, Cr, Mn, Mg, Zn, Wc, Al and
ceramic micro
powder to form
metal mixed powder, and adding the
metal mixed powder into a resin
mixed solution, stirring, and defoaming. The preparation method of the
composite material comprises the following steps of uniformly stirringthe curing agent and the
high polymer material, controlling the temperature to be 20-35 DEG C for preliminary curing, and curing after the temperature is 80-160 DEG C to obtain the finished product. And the mold is made of a
polymer composite material. And the prepared mold is high in strength and
hardness, small in contractibility and good in
sedimentation resistance.
