EPOXY RESIN COMPOSITE FORM-STABLE PHASE CHANGE MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION

An epoxy resin composite form-stable phase change material, a preparation method therefor, and an application. The epoxy resin composite form-stable phase change material is prepared from a cured epoxy resin, a phase change material, a surfactant and a thermally conductive material by means of a casting and molding method. A curing agent in the cured epoxy resin is polyether ammonia, the phase change material is ethylene glycol distearate, and the surfactant is an ethanol solution of sodium dodecyl benzene sulfonate. The composite form-stable phase change material has excellent high temperature resistance, exhibits solid-solid phase change, and is easy to process and prepare. The phase change material phase changes from a crystalline state to an amorphous form, which enables the material to implement the functions of heat absorption and energy storage. The addition of the thermally conductive material improves the thermal conductivity and form stability of the composite form-stable phase change material. The epoxy resin composite form-stable phase change material is filled into a temperature-reducing section of an iQOS cigarette in the form of particles, and can significantly reduce the temperature of the first to third puffs at a filter tip.
