Magnetized solid buoyancy material adopting novel foaming agent and preparation method of magnetized solid buoyancy material

The invention provides a magnetized solid buoyancy material adopting a novel foaming agent and a preparation method of the magnetized solid buoyancy material, and belongs to the technical field of advanced manufacturing. The method comprises the following steps: firstly, plating hollow glass beads by an electro-deposition method; secondly, magnetizing the plating layer on the surface of the microbead; and finally, magnetizing the coated hollow glass beads, fully mixing epoxy resin, a sodium bicarbonate foaming agent and a diluent, adding the coated hollow glass beads and a curing agent, stirring the mixture in an electromagnetic stirrer until the mixture is uniform, and forming the mixture in a mold to obtain a product. The main components of the solid buoyancy material are epoxy resin and hollow glass beads, and the solid buoyancy material is a composite foam material essentially. In order to improve the buffering characteristic of the composite foam material under the impact effect, sodium bicarbonate is ad
