Fluorine modified amino resin and preparation method thereof

The invention discloses a preparation method of fluorine-modified amino resin. The fluorine-modified amino resin is prepared from 37% liquid formaldehyde, melamine, n-butyl alcohol, hexafluorobutanol and xylene organic solvent raw materials. The molar ratio, time, pH and temperature of different reactions are determined through a large number of experiments, so that the optimal process reaction conditions and specific reaction steps are determined, and the amino resin is prepared. The modified melamine formaldehyde resin not only improves the poor stability, poor solubility and the like of melamine formaldehyde resin, reduces the curing temperature, but also improves the effects of adhesive force, flexibility, water and oil repellency and the like after resin film formation, so that the modified melamine formaldehyde resin is more beneficial to industrial production. 本发明公开了一种氟改性氨基树脂的制备方法，它是由37％液体甲醛、三聚氰胺、正丁醇、六氟丁醇、二甲苯有机溶剂原料制成。发明通过大量实验确定不同反应的摩尔比、时间、pH、温度，从而确定最佳工艺反应条件和反应具体步骤，制备得到的氨基树脂。不但改进了三聚氰胺甲醛树脂稳定性差、溶解性差等，降低了固
