摘要： 【目的】解决传统涂层在人体汗液环境中易失效的问题，开发一种以丙烯酸树脂为主体的高耐人工汗阴极电泳涂料。【方法】通过对丙烯酸单体种类和用量进行筛选，研究固化剂用量、中和度、电泳施工及固化工艺参数对涂层性能的影响，得到高耐人工汗性能阴极电泳涂料，并采用傅立叶变换红外光谱仪（FT-IR）表征产物结构。【结果】通过控制树脂合成中单体甲基丙烯酸缩水甘油醚（GMA）用量为 11%~12%、甲基丙烯酸甲酯（MMA）用量为 25%~30%、甲基丙烯酸异冰片酯（IBOMA）用量为 12%~15%和其他功能单体的用量及涂料施工过程中关键影响因素，获得综合性能优异的涂层体系，其耐汗腐蚀>96 h，显著优于同类产品。【结论】本产品可广泛应用于汽车内饰件、运动器材及眼镜、手表等表面防护领域。

Abstract: ［Objective］To address the issue of traditional coatings being prone to failure in human sweat environments，cathodic electrophoretic coatings with high resistance to artificial sweat wasprepared using acrylic resins.［Methods］By screening the types and amounts of acrylic monomers，the effects of curing agent dosage，neutralization degree，electrophoretic construction，and curing process parameters on coating performance were studied，a coating with excellent sweat corrosion resistance wasobtained. The structure of the product was characterized by Fourier transform infrared spectrometer（FT-IR）.［Results］The results indicated controlling the amount of monomer GMA in resin synthesis to be 11%-12%，the amount of MMA to be 25%-30%，the amount of IBOMA to be 12%-15%，the amount of other functional monomers，and the key influencing factors during the coating construction process，a coating system with excellent comprehensive performance was obtained，and the artificial sweat resistance was more than 96 hours，which was significantly better than similar products.［Conclusion］This product was applicated in surface protection for automotive interior components， sports equipment，and accessories such as eyewear and watches.
