摘要:

采用無(wú)皂法制備水性丙烯酸乳液，通過(guò)半連續(xù)滴加工藝進(jìn)行無(wú)皂乳液聚合反應(yīng)，利用該乳液制備的涂料，研磨分散過(guò)程不易破乳，且漆膜與基材的附著力好。通過(guò)分析乳液種類(lèi)、玻璃化轉(zhuǎn)變溫度和配套底漆類(lèi)型對(duì)漆膜的外觀形貌、附著力及耐鹽霧性能影響，得到影響耐鹽霧性能的因素。結(jié)果表明：利用無(wú)皂法制備的丙烯酸乳液水性?xún)?nèi)艙面漆，漆膜致密；玻璃化轉(zhuǎn)變溫度高的無(wú)皂乳液耐鹽霧500小時(shí)內(nèi)具有優(yōu)異的性能，而玻璃化轉(zhuǎn)變溫度低的在1000小時(shí)鹽霧的效果更好一些；與溶劑型環(huán)氧底漆、水性環(huán)氧底漆都具有良好的配套性能，具有優(yōu)異的附著力和良好的耐鹽霧性能。

Abstract:

The mulsifier-free polymerization with semi-continuous adding method with small quantities of the self-made polymerizable emulsifier is studied . The soap-free emulsion is synthesized by methyl methacrylate, vinyl cyanidevinyl cyanide, butyl acrylate, 2-hydroxyethyl acrylate and acrylic acid. The preparation of coating process is not easy demulsification by using soap free emulsion,and the coating has a good adhesion with the substrate. In the application experiment of soap-free emulsion ,the influence of emulsion type, glass transition temperature and the type of primer on the film appearance, adhesion and resistance to salt fog performance are analysized. The physical and chemical properties of self-made soap-free emulsion are evaluated by testing appearance and all kinds of stabilities of the emulsion, and the glass-transition temperature of the self-made soap-free emulsion is determined according to DSC. The results are shown that the self-made soap-free emulsion has good stability, and the self-made soap-free emulsion has basically reached the industrial application effect. Because of no the interface effect of emulsifier， hard and soft monomer proportion of soap-free emulsion in 1.4, there is good adhesion, film density, excellent resistance to salt fog. The waterborne coating of cabin finish is fine and close by using the soap free emulsion. And soap free emulsion which is high glass transition temperature has good resistance to salt fog within 500 hours, while the glass transition temperature is lower, in the 1000 hours salt fog effect is more outstanding. It is shown that the finish has excellent adhesion with different primers and good resistance to salt fog performance.
