【摘要】 <正>生漆是含有漆酚、漆酶、核蛋白、多糖和水的W／O型乳液,不能直接用水稀释而达到易施工的目的。本文研究由漆酚、环氧氯丙烷和聚乙二醇制备反应性漆酚基乳化剂的方法、表面性能及其对生漆的乳化作用。首先,由漆酚(U)和环氧氯丙烷(ECH)合成活性中间体——漆酚基缩水甘油醚(UD),再用 UD与聚乙二醇800(PEG800)在不同的条件下合成漆酚基乳化剂(UE8)(UD:PEG800分别为更多还原

【Abstract】 The active intermediate(UD) was synthesized with urushiol and epichlorohydrinas,then a series of urushiol-based emulsifier (UE8) were synthesized with the intermediate(UD) and polyethylene glycol 800 (PEG800) in different condition. Surface tension of UE8 aqueous solution at different concentration was measured by plate method .It was shown UE8 noticeable decrease the surface tension of water, the critical micelle concentration (CMC) was 1.6~7.9 g/L, the lowest surface tension(25℃) was 36.4 -41.2 mN /m. The particles Of O/W type raw lacquer emulsion was observed by ESEM.更多还原
