摘　　要：分析了钛白粉、消光粉、分散剂种类和添加比例以及生产工艺对UV光固化亚光白面漆的黏度稳定性影响规律。研究指出,UV光固化亚光白面漆热贮存增稠是消光粉和钛白粉的共同作用造成,随着钛白粉添加比例的提高,热贮存增稠比例也明显提高;随着消光粉添加比例的提高,热贮存增稠比例也有所提高;选用合适的分散剂,提高其添加比例可明显降低热贮存增稠比例。另外,生产时最先添加分散剂更利于降低UV光固化亚光白面漆的黏度,生产过程温度不宜超过60℃。This paper analyzes the viscosity stability of UV-curing matte white topcoat influenced by the types and addition ratios of TiO2,matting powder and dispersant and the production process.The study points out that the viscosity rise of UV-curing matte white topcoat after high-temperature storage is caused by the joint action of matting powder and TiO2.The proportion of thickening in high-temperature storage is significantly increased with the increase of TiO2 proportion;the proportion of thickening is also increased with the increase of matting powder proportion.Appropriate and high-proportion dispersants can significantly reduce the proportion of thickening in high-temperature storage.In addition,adding dispersant first is the optimal process for reducing the viscosity of UV-curing matte white topcoat and the production process temperature should not exceed 60℃.
