纳米SiO2对水性标线涂料耐久性能的影响研究OA
Study on the Influence of Nano-SiO2 on the Durability of Water-based Road Markings
道路标线的耐久性对其使用寿命和道路交通安全至关重要.本文以纳米二氧化硅(SiO2)替代钛白粉制备改性水性标线涂料,并通过老化试验研究其色度与磨耗性能耐久性.结果表明,纳米SiO2的引入显著降低涂料亮度因数衰减率和磨耗损失,改性水性标线涂料在40个老化周期时的亮度因数衰减率仅2.01％,磨耗质量损失仅有23.7 mg,色度和磨耗耐久性能显著优于未改性涂料.
The durability of road markings is critical to their service life and traffic safety.In this study,nano-silica(SiO2)was used to replace titanium dioxide to prepare modified waterborne marking paint,and the durability of its chromatic and abrasion resistance was assessed by accelerated aging tests.Results showed that nano-SiO2 significantly reduced luminance factor decay and abrasion loss.After 40 aging cycles,the modified paint exhibited only 2.01％luminance factor attenuation and 23.7 mg abrasion loss,demonstrating markedly better durability than the unmodified paint.
