Abstract: Mono acrylic quaternary ammonium salt was prepared by the continuous reaction of acrylic acid with 2-( chloromethyl) oxirane and N, N-dimethyl ethanolamine. Maleic an-hydride was reacted with triethanolamine to produce diol with inner quaternary ammonium salt, which could be used to react with IPDI, PEG 400 and 2hydroxyethyl methacrylate to form ac-rylate blocked polyurethane quaternary ammonium salts. The triacrylate blocked carbamate formed by reaction of triethanol amine, IPDI and 2-hydroxyethyl methacrylate was reacted with tetrafluoboric acid and hydrochloric acid to give trifunctional quatermary ammonium salts. The structure of quaternary ammonium salts were characterized by 'H-NMR and FT-IR. The composites containing above quaternary ammonium salts cured quickly and its film showed ex cellent antistatic property and water washability.
Key Words:acrylate; polyurethane; UV curing; quatermary ammonium salt; antistatic
静电是一种普遍的物理现象，静电积累不仅影响人们机体平衡及情绪，在工作生产中，静电积累会导致短路、火灾甚至爆炸等危害，因此抗静电问题已经日益引起人们的重视[1]。绝缘材料的抗静电改性方法通常有2种：一是内部添加,将抗静电剂或导电性填料加人到绝缘材料中，共混提高材料的抗静电性或

导电性：二是表面处理，在材料表面采用电镀、涂覆、粘贴等方法使材料表面形成导电层。利用共混改性添加导电填料时，导电填料的用量及加工工艺对材料的性能影响较大，刚性填料的团聚、可溶小分子的迁移使材料抗静电能力下降。涂覆法一般是将抗静电剂组分配制成黏度低的液体，通过浸渍、喷涂或刷涂
