Problems solved by technology

[0002] Epoxy foam materials have the advantages of good thermal stability, mechanical properties, insulation properties, heat insulation properties, and light weight. They have been widely used in the fields of automobiles, electronic potting, aircraft parts, and hull shells. The existing The preparation methods of epoxy foaming materials mainly include physical foaming method and chemical foaming method. Epoxy foaming materials prepared by chemical foaming method generally have large cell size and uneven cell distribution. Increasing the viscosity of the system can reduce the cell diameter, but the apparent density of the material will increase, and it is usually difficult to prepare a microcellular foam material with uniform cells
