摘要
以工业石蜡为主要原料,采用机械搅拌与高速剪切分散乳化机联用的方法制备石蜡乳液,考察了HLB值、乳化剂的选择及其用量对石蜡乳液稳定性的影响。经过对多种乳化剂配方进行筛选,当乳化剂为STJ-1复合乳化剂、HLB值为9.9~10.1,以STJ-1复合乳化剂制备的稳定石蜡乳液成膜性、稀释稳定性均比较好。
Industrial paraffin wax was used as the main raw material and paraffin emulsion was prepared by the combination of mechanical stirring and high speed shearing dispersing machine. The effects of HLB value,emulsifier and its dosage on the stability of paraffin emulsion were investigated. After the choice of various emulsifiers,when the emulsifier is self-made STJ-1 composite,and the HLB value is 9. 9-10. 1,the stable paraffin emulsion with STJ-1 composite emulsifier has good film forming and dilution stability.
