摘要 选用水性丙烯酸乳液、改性氟碳乳液、玻璃粉、自制溶剂和稀土发光填料自主研制一种环保型蓄能自发光道路标线涂料,通过余辉亮度、耐磨性能、黏附性能和抗滑性能检测,得出最优的蓄能自发光道路标线涂料配方。借助分形理论建立稀土发光填料的粒径分布函数,得到整体分形维数(D)、粗粒径分形维数(Dc)、细粒径分形维数(Df),根据道路标线质量要求对分形维数的变化影响规律,建立并验证基于分形维数的稀土发光填料粒径分布预测模型。结果表明:改性氟碳乳液的加入进一步提高了涂料的黏附性能及自清洁性能;在玻璃粉和稀土发光填料的共同作用下,蓄能自发光道路标线的抗滑耐磨性能更佳,且经济效益最好;D表征稀土发光填料内部不规则程度,D值越大,其粒径越细,不规则程度越大;Dc和Df分别反映了稀土发光填料粗细粒径的含量,随Df增大,细颗粒含量增多,蓄能自发光道路标线的余辉亮度和抗滑性能均呈下降趋势,而适当增加粗粒径填料的含量可有效提高蓄能自发光道路标线的余辉亮度和抗滑性能。通过预测模型计算出蓄能自发光标线的各项质量控制指标准确度高,可为稀土类自发光材料选择合理的粒径掺配方案提供一定的理论基础。

Abstract: Water-based acrylic emulsion, modified fluorocarbon emulsion, glass powder, self-made solvent and rare earth luminescent filler was used to independently develop an environmentally friendly self-luminous road marking coating. The optimal formula of self-luminous road marking coating was obtained through the detection of afterglow brightness, wear resistance, adhesion and anti-slip performance. By using fractal theory to establish a rare earth shine filler particle size distribution function, and get the whole fractal dimension (D), coarse aggregate fractal dimension (Dc)and fine aggregate fractal dimension (Df), according to the road marking quality changing with the fractal dimension, build and verify based on rare-earth luminescence filler particle size distribution fractal dimension of the predictive model. The results showed that the addition of modified fluorocarbon emulsion further improved the adhesion property and self-cleaning property of the coating. Under the joint action of glass powder and rare earth luminescent filler, the energy storage self-luminous road marker has better anti-slip and wear resistance, and the economic benefit is the best. D represents the internal irregularity of the rare earth optical packing. The larger the D value, the smaller the particle size, the greater the irregularity. Dc and Df reflect the content of the coarse and fine particle sizes of the energetic rare earth light fillers, respectively. The content of fine particles increases, and the afterglow brightness and anti-skid performance of the road markers with spontaneous light storage decrease with the increase of Df. However, an appropriate increase in the content of coarse particle size can effectively improve the afterglow brightness and anti-skid performance of the road markers with spontaneous light storage. The prediction model can be used to calculate the quality control indexes of the spontaneous energy storage cursor line with high accuracy, which can provide a certain theoretical basis for selecting a reasonable particle size mixing scheme for the rare earth spontaneous light materials.
