UMF树脂对膨胀型乳液防火涂料的改性研究

Modification of Expendable Fireproof Emulsion Coatings with Urea-Melamine-Formaldehyde Resin

以不同配比的UMF树脂与纯丙乳液混溶组成主要成膜基料,用P C N阻燃体系制备膨胀型防火涂料,并对其防火性能进行了测试。实验结果表明:UMF树脂与纯丙乳液按2∶3组成基料,且在涂料中的重量份数为25%时,涂料阻燃性能和施工性能良好。

In this paper,the methods are studied about expandable fireproof coatings made by using Urea-melamine-formaldehyde(UMF) resin and pure acrylic emulsion with different mixture ratio as binder,and P-C-N as fire resistant system,in the meantime,the main factors affecting its fireproof property are discussed.The result shows that the fireproof and build properties are good when the ratio of UMF resin and pureacrylic emulsion is two and three,and their weight account for 25% of the coatings.
