Road performance of waterborne epoxy color coating
To address the problems of dim color and easy cracking on traditional colored road surfaces,a waterborne ep-oxy 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 re-sistance 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.
