基于耐久性的公路工程热熔型标线涂料色度性能研究

Research on Colorimetric Property of Hot-Melt Road Marking Coatings

为了检验公路工程热熔型标线涂料的色度性能,选取了市面上较为常见的5种热熔型涂料进行常规的色度性能检测,进行了涂膜热稳定性试验、水稳定性试验、耐压力老化试验和测试了耐紫外线老化试验前后色度的变化。结果表明,选取的5种热熔型标线涂料的色度性能都合格,热稳定性和耐压力老化性较好,但水稳定性和耐紫外线老化性偏弱。

In order to exam the colorimetric property of the hot-meh coating, five types of common hot-inch coatings available in the market were chosen to conduct normal colorimetric property tests. A comparative analysis of colorimetric property was conducted by means of ther- mal stability test, water stability test, PAV test and QUV test. The results showed that the five types of coatings provided qualified colorimetric property, good thermal stability and PAV per- formance but weak water stability and QUV performance.
