摘要:

为解决传统彩色路面色彩暗淡、易开裂等问题,以水性环氧树脂、水性胺类固化剂、成膜助剂、颜填料和防滑砂为主要成分,制备路用水性环氧彩色涂层,采用红外光谱和扫描电子显微镜对水性环氧树脂固化体系微观形貌进行分析,并通过拉伸黏结强度试验、冻融循环试验和紫外老化试验等分析填料种类、防滑砂用量等对彩色涂层路用性能影响。结果表明,水性环氧树脂固化过程中形成性能稳定的固化产物;润湿剂对涂层附着力有增强作用;涂层抗滑性和耐磨性随防滑砂用量增加及目数减小而增长;涂层耐冲击性随填料用量增加而逐渐提高;添加紫外线吸收剂能提高涂层耐紫外线老化性。

Abstract:

To address the problems of dim color and easy cracking on traditional colored road surfaces, a waterborne epoxy color coating was prepared by using waterborne epoxy resin, waterborne amine curing agent, film⁃forming agent, pigment, filler, and anti⁃skid sand as main components. The microstructure of the waterborne epoxy resin curing system was analyzed by Fourier⁃transform infrared spectroscopy and scanning electron microscopy. The effects of filler type and content of anti⁃skid sand on the road performance of color coating were investigated by tensile bond strength test, freeze⁃thaw cycles, and ultraviolet aging test. The results indicated that the stable cured products were formed during the curing process of waterborne epoxy resin. The incorporation of wetting agent improved the adhesion of the coating. The skid resistance and wear resistance of the coating increased with an increase in the addition amount of anti⁃skid sand but with a decrease in the mesh number. The impact resistance of the coating increased gradually with an increase in the addition amount of filler. The addition of an ultraviolet absorber improved the UV⁃aging resistance of the coating.

Key words: color coating, waterborne epoxy resin, curing characteristics, road performance
