甲醚化三聚氰胺甲醛树脂的合成及对卷材涂料性能影响

Synthesis of Methyl Etherified Melamine for Maldehyde Resin and its Effect on the Properties of Coil Coatings

分别制备了高甲醚化三聚氰胺甲醛树脂CLK-03和高亚氨基三聚氰胺甲醛树脂CLK-25,通过红外色谱、凝胶色谱和分析滴定等方式对样品进行了详细剖析;考察在海蓝色卷材聚酯面漆涂料配方中的应用性能,固定两个样品添加固含总量,调整不同的添加比例,在CLK-03和CLK-25比例为3∶1条件下,获得的漆膜综合性能优异。

The high methyl etherified melamine formaldehyde resin CLK-03 and the high imino melamine formaldehyde resin CLK-25 were respectively prepared,and the samples were analyzed in detail by infrared chromatography,gel chromatography and analytical titration.Investigate its application performance in the formulation of marine blue coiled polyester topcoat paint,fix the total solid content of the two samples and adjust the different addition ratios.Under the condition that the ratio of CLK-03 to CLK-25 is 3∶1,the overall performance of the paint film obtained is excellent.
