By testing the water-based two-component polyurethane yellow finish,the environmentally-friendly region of spraying construction was explored,the ratio of aqueous hydroxy acrylic resin to aqueous hydroxy alkacid resin quality,dosage of curing agent,paint film thickness and drying time on paint film hardness were studied,and finally the paint film that meet the requirements of rail transit protection was got.
