基于耐候性与耐磨性提升的公路标线涂料改性研究

Research on the Modification of Road Marking Coatings Based on Improved Weather Resistance and Wear Resistance

摘要

针对公路标线涂料在服役过程中因耐候性与耐磨性不足导致使用寿命偏短的问题，本文开展基于材料改性的性能提升研究。首先分析涂料老化与磨损的微观机理，明确紫外辐射、温湿循环及车辆荷载是性能衰减的主要诱因。在此基础上，筛选适宜的耐候改性剂与耐磨填料，优化复合改性涂料的配比方案。通过制备改性试样并设计加速老化与磨损试验，系统研究紫外老化、温湿循环对涂料性能的影响规律，探讨不同载荷条件下的磨损特性。结果表明，改性材料能够有效延缓涂料基体的光氧降解进程，增强涂层表面抗磨削能力。本文为高性能公路标线涂料的配方设计与工程应用提供了理论依据。

Abstract

To address the issue of shortened service life caused by insufficient weather resistance and wear resistance in road marking coatings, this study investigates performance enhancement through material modification. First, the microscopic mechanisms of coating aging and wear are analyzed, identifying ultraviolet radiation, thermal-humid cycling, and vehicular loading as the primary factors leading to performance degradation. Based on this, suitable weather-resistant modifiers and wear-resistant fillers are selected, and the formulation of composite modified coatings is optimized. By preparing modified samples and designing accelerated aging and wear tests, the effects of UV aging and thermal-humid cycling on coating performance are systematically studied, along with the wear characteristics under different loading conditions. The results indicate that the modified materials effectively delay the photo-oxidative degradation of the coating matrix and enhance the surface abrasion resistance. This study provides a theoretical basis for the formulation design and engineering application of high-performance road marking coatings.
