重点介绍了紧凑型水性B1B2工艺配套1 K清漆的涂装性能,主要从1 K清漆和2 K清漆的成膜机理、涂膜外观性能、涂膜抗擦伤性能、老化性能等方面进行了对比验证分析。结果表明:水性B1B2工艺配套1 K清漆工艺的涂膜性能与配套2 K清漆工艺的涂膜性能存在差距,但配套1 K清漆在成本等方面具有一定的优势。

In this paper,the coating performance of compact waterborne b1 b21 k varnish is mainly introduced,the film-forming mechanism,film appearance performance,film abrasion resistance and aging performance of 1 K Varnish and 2 K varnish were compared and verified,the results show that there is a gap between the film performance of B1B2 process with 1 K varnish process and that of B1B2 process with 2 K varnish process,however,1 K varnish has certain advantages in cost.
