Abstract: Quick-drying waterborne coating technology is environmental-friendly and can improve road safety for its long-lasting adhesion to glass beads，high retro-reflectivity，good night visibility and high wear resistance. It occupies a leading position in road marking
materials profit from its high construction efficiency and low comprehensive cost. In this paper，the application characteristics of four major road marking coatings such as hot melt，solvent-based，water-based and two-component were summarized. The quick-drying acrylic latex for waterborne road marking coatings and its technical requirement were introduced emphatically，and the existing application problems and reason were analyzed.

Key words: road marking coatings, waterborne, acrylic emulsion, safety, long-term retro-reflectivity, retroreflection brightness coefficient, quick-drying

摘要： 快干型水性标线涂料技术绿色环保，具有持久的玻璃珠黏附力和优异的反光性，夜间辨识性高，经久耐磨，有助于提升道路安全，且施工效率高，综合成本较低，在标线材料应用中占据主导地位。本文总结了热熔型、溶剂型、水性和双组分四大类道路标线涂料的应用特点，重点介绍了水性标线涂料成膜物快干型丙烯酸乳胶及其技术要求，以及水性标线涂料在应用中存在的问题并分析了原因。
