为了改善道路标线涂料的高温稳定性及抗磨耗性能,减少陶瓷固体废弃物对环境的污染,以热熔型涂料为基材,外掺房建陶瓷颗粒、卫具陶瓷颗粒、工艺陶瓷颗粒,设计轮辙试验和湿轮磨耗试验并辅以扫描电镜微观观测,分析陶瓷颗粒类型及掺量对道路标线涂料轮辙深度、磨耗值的影响。结果表明:掺入废旧陶瓷颗粒后,道路标线涂料高温稳定性及抗磨耗性能均得到较大提高,尤以掺工艺陶瓷颗粒涂料效果最为明显,其合理掺量约为20%。
In order to improve the high temperature stability and abrasion resistance of road marking paint and reduce the environmental pollution caused by ceramic solid waste, the hot-melt paint is used as the base material, and the ceramic building materials, the sanitary ware ceramic granules, the process ceramic granules, Wheel tracking test and wet wheel wear test were combined with microscopic observation by scanning electron microscopy to analyze the influence of ceramic particle type and dosage on track depth and wear value of road marking paint. The results show that the high temperature stability and abrasion resistance of road marking paint have been greatly improved after the waste ceramic particles are mixed. Especially, the effect of ceramic powder coating is the most obvious. The reasonable dosage is about 20%.
