Description

technical field

[0001] The invention relates to a composite shell phase change energy storage microcapsule and a preparation method thereof. It belongs to the phase change energy storage microcapsule preparation technology. Background technique

[0002] Phase change energy storage has been widely used in solar energy utilization, "peak shifting and valley filling" of electric power, waste heat recovery and energy saving of buildings and air conditioners. For the convenience of use, microencapsulation of phase change materials is an effective Methods. The methods of microencapsulation mainly include interfacial polymerization, in-situ polymerization, phase separation and spray drying, etc., and the microencapsulation of phase change materials is generally prepared by in-situ polymerization. Ishiguro of Japan, Maohong Maeda and others (CN1161364A) have made shells that are phase-change energy storage microcapsules of single-layer melamine resin, b...
