Abstract: Micro-encapsulated paraffin was prepared by in-situ polymerization method with urea-formaldehyde resin as shell and KCl as the microcapsulated accelerant.The experimental results showed that the microcapsules were successfully coated by urea-formaldehyde with 16.8μm of the mean particle size and 500nm of the size of capsule wall.The TGA results shown that the microcapsules had higher thermal stability than paraffin.The microcapsules showed the melt point and enthalpy were 33.29℃ and 128.51J/g,respectively,which were showed the higher thermal storage performance than the microcapsules added NaCl.
