摘　　要：在汽车涂装中,水性免中涂涂装工艺因工艺流程少、污染排放和能耗低而受到愈来愈多的关注,它将成为今后汽车涂装的主流。本文从涂膜性能指标、面漆颜色效果、闪干流平时间和清漆设计等方面对水性免中涂涂装工艺进行了研究,分析了清漆厚度、第2道面漆的喷涂遍数、中间闪干流平时间和旋杯型号选择对汽车外观质量的影响以及存在的问题,获得了实现最佳外观的汽车水性免中涂涂装工艺方案。In automobile coating, water-based midcoat-free coating process has aroused more and more attention and will became the mainstream for the future due to its shortened process flow, less pollution discharge, and lower energy consumption. In this article, the water-based midcoat- free coating process was studied from aspects of coating performance indexes, topcoat color effect, flash leveling time, and varnish design, etc. The influence of varnish thickness, spraying number for the second topcoat, medium flash leveling time, and rotary cup selection on the automobile appearance quality and some existing problems were analyzed. A scheme for realization of optimal automobile appearance by using the water-based midcoatfree coating process was obtained.
