摘　　要：以甲基丙烯酸二甲氨基乙酯(DMAEMA)分别与溴乙烷、正溴丁烷、苄氯、硫酸二甲酯以及3-氯-2-羟基丙基甲基丙烯酸酯(CHPMA)反应合成了一系列可UV固化的单、多官能团抗静电季铵盐。将UV固化涂料技术和抗静电技术相结合,制备出UV固化抗静电涂料。研究了涂膜光固化时间、耐水洗性以及热稳定性,并探讨了抗静电剂种类以及添加量与抗静电性能的关系。结果表明,该涂料光固化速度较快,涂膜表面电阻下降到1×107Ω,水洗10次表面电阻无明显变化,具有优良抗静电性以及耐水洗性,且受湿度影响不大。固化膜的TG分析表明,该UV固化抗静电涂料具有较好的热稳定性。A series of antistatic quaternary ammonium salts with single or multiple UV-curable functional group were synthesized from the reaction of 2-（ dimethylamino） ethyl methacrylate（ DM AEMA） and ethyl bromide,n-butyl bromide,benzyl chloride,sulfuric acid dimethyl ester and 3-chloro-2-hydroxypropyl methacrylate（ CHPMA） respectively. The UV-curable antistatic coating was obtained by combining UV-curable coatings technology with antistatic technology. Curing time,washability and thermal stability of the UV-curable films were studied. The influences of kinds and concentration of the antistatic agent on the antistatic properties were discussed. The results showed that the surface resistivity of coating film decreased to 1 × 10^7Ω and hardly changed after washed 10 times,and the UV-curable coating could be cured quickly to give a film with excellent antistatic properties and washability. The results of the TG test showed that the antistatic UV curing coating has good thermal stability.
