Synthesis and Characterization of Phase Change Thermal Storage Waterborne Styrene-Acrylic Emulsion Coating

摘要

Ploy (N-hydroxymethyl acrylamide)/polyethylene glycol (PNHMPA/PEG) interpenetrating polymer network gel was prepared as new form-stable phase change thermal filler, and IPN distribute evenly in the new phase change thermal conversion coating. The polarizing microscope shows that EPN is crystalline, which proves its heat storage capacity. The DSC results indicate that the new PCM conversion coating has a good energy storage capability and an available phase transition temperature. The TG results show that the new coating has good thermal stability, and IPN effect of thermal decomposition is not affected by the coating composition.
