The polyurethane coating was prepared by spraying. The influence of process parameters on coating properties were discussed, such as pressure, speed of gun, spraying distance and the initial temperature of the ma-terial. The optimal spraying process parameters were obtained. Coating with good performance could be giren when the pressure was 0.70~0.75 MPa, gun speed was 40~60 cm/s, spraying distance was 15~20 cm, the range of initial temperature of material was 40~70 ℃.
