摘要： 【目的】开发一种适合丙烯酸阴极电泳涂料体系使用的彩色浆，解决传统色浆与丙烯酸阴极电泳涂料配套后贮存稳定性差、外观橘皮的问题。【方法】使用不同的功能性丙烯酸单体制备色浆用分散树脂，研究不同单体的用量、 n（环氧基团） ∶n（活泼氢）、颜基比、固体分、分散剂用量及研磨工艺等条件对色浆稳定性和性能的影响。【结果】通过控制丙烯酸羟乙酯（ HEA）质量分数为 14%~16%、丙烯酸丁酯（ BA）质量分数为 16%~ 17%、n（环氧基团） ∶n（活泼氢）为 1∶（1. 2~1. 4）及 BY-190分散剂用量为 2%和色浆研磨过程中一些关键影响因素，成功开发出具有高贮存稳定性（ >6个月）和优异漆膜外观的彩色浆。【结论】该彩色浆可拓展丙烯酸阴极电泳涂料在电子元件、建筑五金件、卫浴等高端领域的装饰应用，其工艺参数对工业化生产具有指导价值。

Abstract: ［Objective］ A colored paste suitable for acrylic cathodic electrophoretic coatingsystems was developed to solve the problems of poor stability and orange peel of traditional color pasteafter being matched with acrylate cathodic electrophoretic coating.［Methods］ Functional acrylic monomers were used to prepare dispersion resin for color paste，and the effects of different monomer content，n（epoxy group）∶n（active hydrogen）， pigment-base ratio，solid content，dispersant amount， and grinding on the stability and performance of color paste were studied.［Results］ The results showed that by controlling the monomer HEA content of 14%-16%，BA content of 16%-17%，n（epoxy group）∶n（active hydrogen）of 1∶（1. 2-1. 4），and the amount of BY-190 dispersant 2%，and some key factors in the grinding process of pigment paste，colored paste with high storage stability（no precipitation for more than 6 months at room temperature）and excellent paint film appearance was successfully developed.［Conclusion］The decorative application of acrylic cathodic electrophoreticcoating in high-end fields such as electronic components，building hardware，anditary ware were significantly expanded by the color paste，while its optimized process parameters provide valuable guidance for industrial production.
