Summary:This paper first designed the molecular structure of the water-soluble polyurethane phase change material. Taking HDI (hexamethylene diisocyanate), PEG (polyethylene glycol), chain extender (DMPA (dimethylolpropionic acid), BDO (1,4- butanediol), EDA (ethylenediamine)), catalyst (DBTDL (February acid dibutyl tin)), neutralizing agent (TEA (triethylamine)) as the raw material, the paper then prepared the waterborne polyurethane phase change material, which is available for wet spinning process. The particle size, appearance, storage stability, water absorption, tensile strength and elongation at break of the WPUPCM emulsion were then tested. Moreover, the influences of reaction temperature, reaction time, R value (ie -NCO / -OH molar ratio), PEG relative molecular mass and DMPA content on the WPUPCM performance indicators were investigated. The study indicated that reaction temperature, reaction time, R value, PEG relative molecular mass and DMPA content show various influences on WPUPCM performance indicators. Therefore, in order to meet the requirements of practical application and determine optimal formulation and process parameters, further relevent studies based on comprehensive considerations of all factors are needed.
