摘要： 采用十三氟辛醇（ TEOH-6）、异佛尔酮二异氰酸酯（ IPDI）、三乙醇胺（ TEOA）自制含氟二元醇（ DE-TEOH）；并采用六氯环三磷氰、对羟基苯甲醛、硼氢化钠合成六臂型阻燃单体；以异佛尔酮二异氰酸酯（ IPDI）、聚碳酸酯二元醇（ PCDL）、二羟甲基丁酸（ DMBA）、含氟二元醇（ DE-TEOH）、季戊四醇三丙烯酸酯（PETA）为主要原料合成— NCO半封端线型聚氨酯；将六臂型阻燃单体加入聚氨酯体系，采用无皂相反转乳化工艺制成了含氟、氮、磷复合改性水性 UV固化六臂型阻燃聚氨酯（ UV-WFPU）。通过红外光谱、核磁共振氢谱对 UV-WFPU的结构进行表征，并对胶膜的性能进行了研究，考察了含氟二元醇的添加量以及六臂型阻燃单体加入对胶膜结构和性能的影响。结果表明：与传统的聚氨酯相比，六臂型阻燃单体的加入，胶膜的阻燃性能大幅度提高，极限氧指数（ LOI）提高了 45%；随着自制二元醇添加量的增加，胶膜吸水率降低，接触角增加，热稳定性提高。

Abstract:

Trifluorooctyl octanol（TEOH-6）， isophorone diisocyanate（IPDI）， triethano-lamine（TEOA）and hexachlorocyclotriphosphonate were used to prepare fluorine-containing diol（DE-TEOH）. A six-arm flame retardant monomer was synthesized by using p-hydroxybenzaldehyde and sodium borohydride. Isophorone diisocyanate（IPDI）， polycarbonate diol（PCDL）dimethylolpropionic acid（DMPA），fluorine-containing diol（DE-TEOH），pentaerythritol triacrylate（PETA）were used as the main raw material to synthesis —NCO semi-capped linearpolyurethane. Then the six-arm flame retardant monomer was added into the polyurethanesystem and the fluorine，nitrogen and phosphorus composite modified water-based UV-curing six-arm flame retardant polyurethane（UV-WFPU）was made by a soap-free reverse emulsificationprocess. The structure of UV-WFPU was characterized by IR and 1H NMR，and the propertiesof the film were studied. The effect of amount of fluorine-containing diol and incorporation ofsix-arm flame-retardant monomer on the structure and performance of the film wasinvestigated. The results showed that compared with the traditional polyurethane，the incorporation of six-arm flame retardant monomer could greatly improve the flame retardantperformance of the film，and the limiting oxygen index（LOI）was increased by 45%. With the increasing of DE-TEOH，the water absorption rate of the film was descreased and the contactangle and the thermal stability were increased.
