一种新型水性气雾漆的研制

Preparation of a New Water-borne Aerosol Paints

以水溶性丙烯酸树脂为成膜物质,以水为助溶剂,以二甲醚(DME)为抛射剂,制备了一种水性气雾漆。通过单因素试验法,对树脂、分散剂、消泡剂、料气比等影响因素进行探讨。试验结果表明:当分散剂EFKA-4330用量为0.35%,消泡剂Nopco8034L用量为0.2%,m(漆料)∶m(二甲醚)=1∶1～1∶1.5,缓蚀剂ATC701用量在0.1%～0.3%时,水性气雾漆的性能可与溶剂型气雾漆相媲美,且不含有大量有机溶剂,VOC含量大幅度降低,满足人们的环保要求。

With soluble acrylic resin as film forming material and dimethyl ether（DME） as propellant,we have prepared aerosol paints.Through single factor test method,the influencing factors,such as resin,dispersant,defoamer and material-gas ratio,are investigated,showing that with dispersant EFKA-4330 amount of 0.35%,defoamer Nopco8034L amount of 0.2%,m（paints）∶m（dimethyl ether） of 1∶1 to 1∶1.5 and the inhibitor ATC701 amount of 0.1%～0.3%,the performance of the aerosol paints is as good as solvent-borne paints,with greatly reduced VOC and without large amount of organic solvent,meeting the environmental requirement of human beings.
