Abstract
As an essential part of traffic safety facility, traffic markings play a crucial role in controlling road traffic and improving traffic safety. However, the conventional solvent-based and hot-melt marking paints have deficiencies such as high cost, poor retro-reflectivity, inferior aging resistance, and large environmental pollution. Hence there is an urgent need to seek new marking paint products that can overcome the aforementioned deficiencies. Acrylic acid-based waterborne traffic marking paints have been found highly durable and environmental friendly, and capable of facilitating rapid construction, are considered as the best marking paint candidate with respect to overall performance in the whole life-cycle assessment, and as one of the major development directions in the future. In recent years, intensive and fruitful research efforts have been made in improving the working performances of acrylic acid-based waterborne traffic marking paints from the perspectives of physical modification, chemical modification and mixing proportion optimization. And the rapid development of nano-materials and rare-earth luminescent materials also provides infinite possibilities for acrylic acid-based waterborne paints. However, acrylic acid-based paints haven't yet found wide applications in traffic engineering, and also needs further improvement in comprehensive performance. Moreover, current research has been concentrated in the macroscopic scale domain. The microscopic properties of acrylic acid-based waterborne paints have not been thoroughly studied, and the understanding of the relationship between macroscopic properties and microscopic structural properties remains unclear. The existing performance evaluation methods of acrylic acid-based waterborne paints cannot fully reflect the whole-life-cycle functionality and durability requirements of the traffic marking paints. This urges the establishment of a comprehensive and systematic evaluation system for acrylic acid-based waterborne traffic marking paints. Furthermore, some researchers, though have studied the performance evolution of the acrylic acid-based coatings during their service life, mostly focused on retro-reflective performance and left the performance prediction model immature. In addition, there can be found few works studying the performances and underlying mechanisms of the paint-pavement adhesion interfaces. After depicting necessary basic knowledge about chemical structure and properties of water-based acrylic acid emulsions, this review summarizes systematically the main present research progress of acrylic acid-based waterborne traffic marking paints from the perspectives of modification methods, mixing proportion optimization, and performance evaluation methods. It ends with a discussion on currently existing problems and the future development trend.
