摘要: 无机富锌涂料具有干燥迅速、施工简便等优点,但漆膜较厚时容易龟裂。 采用对水解液进行改性及配方优化可克服以上缺点。 本研究重点讨论了物料对涂膜性能的影响,论述了无机富锌底漆的研制过程,并给出无机富锌的最佳配方。 通过试验证明锌粉含量、云母粉、聚乙烯醇缩丁醛(PVB)等对无机富锌底漆性能有显著的影响。 最终得到涂膜的各项性能完全达核电站技术规格书的要求。

Abstract: The inorganic zinc-rich coatings have advantageous properties such as fast drying and simple application process, while overshadowed by its disadvantageous property such as crack which might result in difficult follow-up coating process. The modification of hydrolysate and formula optimization can overcome the disadvantage. The influence of components on film property is investigated. Moreover, the preparation and optimal formula of inorganic zinc-rich coatings have been described. The results indicate that zinc content, mica powder and PVB have an obvious effect on the film performance. The obtained coatings exhibit good comprehensive performance qualified to technical specifications of the nuclear power plant.
