Epoxy resin foam material containing perforated structure and preparation method thereof

The invention discloses an epoxy resin foam material containing a perforated structure and a preparation method thereof. The epoxy resin foam material containing the perforated structure comprises the following components by weight: 100 parts of the epoxy resin, 0.5-220 parts of a curing agent, and 1-60 parts of polymer expended microspheres. The epoxy resin foam material containing the perforated structure has the advantages of light weight, high strength, and good noise reduction effect, and is suitable for the application of the sound absorption material. In addition, the preparation method for the epoxy resin foam material has the characteristics of smart conception, simple and convenient operation, safety, environment-friendliness, small energy consumption, and low cost, and is suitable for the industrial production.
