| 摘 要：采用連續乳液聚合法合成了有機氟硅改性苯丙乳液，研究了乳化劑、MBFA-12、DB-151用量對乳液穩定性的影響。結果顯示，乳化劑用量為0.8%~1.0%（m／m），m（MBFA-12）∶m（DB-151）=1∶1，用量各為4 g時(shí)，合成的氟硅改性苯丙乳液具有良好的穩定性。其涂層與水的接觸角為128.5°，具有超疏水性。合成的氟硅改性苯丙乳液在建筑防水涂料、油水分離等領(lǐng)域中具有一定應用前景。 |

| Abstract：In order to increase the hydrophobic property of the styrene-acrylic emulsion, styrene-acrylic emulsion modified using organic fluoride and silicone was synthesized through continuous emulsion polymerization. The effect of the loading of emulsifier, MBFA-12 and DB-151 on the emulsion stability was studied. The results showed that, when the amount of emulsifier was 0.8%~1.0%, the usage of both MBFA-12 and DB-151 was 4 g, the average size of the emulsion was smaller while the modified emulsion was more stable. The contact angle between emulsion film and water was 128.5°, showing that the film had super hydrophobility. The modified styrene-acrylic emulsion had promising application in the field of waterproof coating and oil-water separation. |
