    摘要：以环烷油为基础油，通过对不同乳化剂组合、不同的HLB值、稀释比例等对脱模剂工艺进行调整，研制了一种水性混凝土脱模剂。该脱模剂的最佳工艺配方为：基础油为环烷油，乳化剂组合为S-80/PEG800-MO，HLB值为9.5，乳化剂用量为6%。试验结果表明，该脱模剂的稳定性、成膜时间、脱模效果较为理想。

    Abstract：On the basis of naphthenic oil，using different combination of emulsifiers，HLB values，dilution ratio to adjust the release agent technology，which can develop a water-soluble concrete release agent. The optimum technical formula is that the base oil is naphthenic oil，Emulsifier combination is S-80/PE G800-MO，HLB value is 9.5，and the amount of emulsifier is 6%. The results showed that release agent has excellent performance on the stability，film time，and demolding effect.
