| 摘 要：合成了一種有機氟改性苯丙乳液，研究了乳化劑用量、引發(fā)劑用量、交聯(lián)單體用量、氟單體用量對乳液穩定性及附著(zhù)力的影響。結果顯示，乳化劑用量為0.8%~1.0%，引發(fā)劑用量為0.8%，交聯(lián)單體用量為3%，氟單體用量為16%時(shí)，制備的改性苯丙乳液具有良好的穩定性，在馬口鐵上的附著(zhù)力為11.7 MPa。膜層具有良好的耐水性和耐油性，鉛筆硬度為2H，與水之間的接觸角為118.2°。所制備的膜層在油水分離中具有一定的應用前景。 |

| Abstract：A modified styrene-acrylic emulsion was synthesized, and the effect of the weight ratios of emulsifier, initiator, crosslinking agent and fluorine monomer on the stability and adhesion of the emulsion were evaluated. The results showed that, in a typical reaction process with following conditions: the amount of emulsifier was 0.8~1.0%; the usage of APS was 0.8%; the usage of crosslinking monomer was 3%; the usage of fluorine monomer was 16%, the obtained emulsion was stable and the adhesion on tinplate was 11.7 MPa. The properties of films prepared from the emulsion were as follow: excellent water and oil resistance with a pencil hardness of 2H, the contact angle between water droplet and the film of 118.2°. The study presents that the film has some potential applications in the oil-water separation. |
