针对太阳能利用以及一些蓄热场合，通过示差扫描量热法（DSC）选取了合适的石蜡，以脲醛树脂为囊壁，采用原位聚合法制备了石蜡一脲醛树脂微胶囊，拟将此微胶囊添加到上述应用场合的传热流体中，提高传热流体的热容。实验结果表明，乳化剂OP更适合于熔点60℃石蜡微胶囊的制备。
針對太暘能利用以及一些蓄熱場閤，通過示差掃描量熱法（DSC）選取瞭閤適的石蠟，以脲醛樹脂為囊壁，採用原位聚閤法製備瞭石蠟一脲醛樹脂微膠囊，擬將此微膠囊添加到上述應用場閤的傳熱流體中，提高傳熱流體的熱容。實驗結果錶明，乳化劑OP更適閤于鎔點60℃石蠟微膠囊的製備。

In this thesis, certain paraffin was chosen by the differential scanning calorimetry （DSC） test for core material, which is adapted to solar energy utilizing and the other thermal storage system; urea-formaldehyde polymer was used as wall material. Urea-formaldehyde microencapsulated paraffin by means of situ polymerization. It will be added into heat transfer fluid of solar energy utilizing and other thermal storage system, to increase the specific heat of fluid. The effect of emulsifier on the performance of microencapsulation was studied. The experimental results showed that emulsifier OP is more suitable for the preparation of microencapsulated paraffin whose melting point is 60℃.
