摘要： 采用先喷涂闪光漆、再喷涂素色漆，最后喷涂透明清漆的特殊工艺制备了高彩度双涂层色漆，其膜厚相对以往传统单层色漆高，在量产前遇到了各种涂装弊病，如车身色差控制、飞溅污染、喷涂发花、“痱子”、色差修补等。对这些难点课题产生的原因进行了分析，并给出了有效的解决方案。同时，针对高彩度双涂层色漆的量产应用，从机、料、法、环的角度梳理出需要重点管理的项目，提出有效的对策，以确保量产颜色的稳定性。

Abstract: A special process of first spraying flash paint，then spraying plain paint，and finally spraying transparent varnish was used to prepare a high color dual coating paint.Compared to traditional single-layer paint systems，this new system had higher film thickness.There were various quality issues on the high chroma two-layer basecoat paints before massproduction，such as body color difference，splashing pollution，spots，“blister”defects，repair color difference，and other series of problems. An analysis was conducted on the causes ofthese difficult issues and effective solutions were provided. At the same time，for the mass production application of high color dual coating paint，key management projects need to be sorted out from the perspectives of machine，material，method，and environment，and effective countermeasures are proposed to ensure the stability of color in mass production.

Key words: high chroma, two-layer basecoat paint, color difference, splashing pollution, application management
