| 摘 要： | MCPU清漆应用于大批量工件的涂装生产线时，通过配入少量的相对分子质量小的多元醇组分，从而适当引入-NC0／-OH交联机制，由于-NCO／-OH与原有的-NCO／H20两者双重交联机制的迭加，强化了漆膜的交联固化进程，在生产线上经过低温烘烤后，漆膜的即时性能可达到生产工艺要求，而漆膜最终亦能达到MCPU应有的优良性能。该强化交联固化技术有利于涂装工艺中节能与提高生产效率。

| Abstract: | When MCPU lacquer is applied in coating lines of mass production, a bit of small molecular polyol is added to introduce -NCO/-OH crosslinking mechanism, which can enforce the crosslinking curing procedure by forming a double crosslinking system together with the original --NCO/H20 mechanism. As a result, both the immediate and the ultimate performances of the coatings thereof can reach the requirements only after low - temperature baking cure on line. The enforced crosslinking curing technology not only helps improve the production efficiency, but also helps save the energy during coatings. |
