Abstract

The invention discloses an environment-friendly structure foam material and a preparation method and application thereof. The environment-friendly structure foam material is composed of, by weight parts, 55-63 parts of polystyrene, 72-79 parts of phenolic resin, 5-8 parts of alum, 23-29 parts of curculigo orchioides extract, 10-15 parts of sodium dodecyl sulfate and 3-8 parts of hydroxyethyl acrylate. The curculigo orchioides undergoes soaking, steam explosion, drying, reflux condensation extraction, centrifugation and concentration to obtain the curculigo orchioides extract. The phenolic resin is placed into absolute ethyl alcohol to be heated, alum water solution is added for pretreatment, and the polystyrene, the curculigo orchioides extract, water, the hydroxyethyl acrylate and the sodium dodecyl sulfate are added sequentially to be placed in a mold to stand and be cured to obtain the environment-friendly structure foam material. The environment-friendly structure foam material has good thermal insulation performance, flame retardant performance and compression performance, improves the thermal stability, further has sound absorption and sound insulation performance, is convenient in preparation process and operation and is an environment-friendly material.
