高固体分脲醛树脂涂料的研究

STUDY ON HIGH SOLID UREA-FORMALDEHYDE RESIN PAINT

叙述了高固体分脲醛树脂涂料的制备方法。该涂料是水溶性的脲醛树脂齐聚物,在固体含量高达95％时,涂4杯粘度仅150秒左右。与一般的脲醛树脂比较,该树脂具有不燃、无毒和无污染的优点,而且配制的涂料性能良好。讨论了原料配比、工艺条件对树脂聚合度的影响,以及该涂料的催化机理。

It presented the production of high solid urea-formaldehyde resin paint, which was made based on a water-soluble urea-formaldehyde oligomer, the viscosity (Ford cup 4) being only about 150 seconds when NV reaches 95%. Compared with common urea-formaldehyde resin, it is featured by its non-flammability, nontoxicity, no pollution and good film properties. The formulation, effects of processes on polymerization degree and curing mechanism of the paint were discussed.
