【摘要】 丙烯酸丁酯、丙烯酸辛酯、丙烯腈等单体经游离基聚合反应，添加阴、阳和非离子型复合表面活性剂及流平剂、增塑剂等制备高光泽水性清漆。清漆固体分４５～５０％，光泽９５％，硬度６Ｈ，耐磨性１０００转损失０．０１ｇ，漆膜耐水，耐汽油，耐化学腐蚀。叙述了制备工艺。讨论了单体配比、表面活性剂类型、引发剂用量和反应温度等因素对漆膜性能的影响。经实验确定，阴离子型、非离子型和阳离子型表面活性剂比例为１∶０．２～０．５：０．４～０．８，引发剂用量为单体总量的０．２～０．４％，反应温度７０～７５℃。列出了清漆主要技术指标。更多还原

【Abstract】 AbstractA high gloss water-borne varnish has been preparedwith butyl acrylate, octyl acrylate and acrylonitrilemonomers and cationic, anionic and nonionic com-pound surfactants, leveling agent and plasticizers, etc.The varnish has solid content of 45～50%, gloss95%, hardness 6H, abrasion loss 0.01g(1000cycles), and good water, gasoline and chemical resis-tance. The preparation process, and effects ofmonomer ratio, types of surfactants, amount of initia-tors and temperature on the film properties were dis-cussed. Experimentally, the optimum conditions havebeen found, anionic/nonionic/cationic surfactants ra-tio is 1/0.2～0.5/0.4～0.8, initiator usage is 0.2～0.4% of total monomers, reaction temperature 70～75℃. The technical specification was given.更多还原
