摘　　要：水性金属漆中金属颜料的定向排列极大地影响着漆膜的外观,因此选择合适的流变助剂起着关键性的作用。本文介绍了水性金属漆中常用流变助剂的种类、分子结构以及应用机理,探讨了典型流变助剂对漆膜外观性能的影响。研究表明,片状硅酸盐LAPONITE RD与AQUATIX 8421蜡乳液同时作为流变助剂,金属颜料定向排列较为优异,且成本上更为经济。The directional arrangement of metallic pigments in waterborne metallic coatings greatly affects the appearance of film,so the selection of appropriate rheological additives plays a key role.In this paper,the types,molecular structures and application mechanism of rheological additives typically used in waterborne metallic coatings are introduced.The effects of typical rheological additives on the appearance properties of films are discussed.The results show that the directional arrangement of metal pigments is better and cost effective when silicate Laponite RD and Aquatix 8421 wax emulsion are used as synergic rheological additives.
