Abstract：In order to solve the problem that the low adhesive force of polymer-based protective coatings applied for concrete used in marine environment and total immersion area,the adhesion of four different types of primers applied for concrete protective coatings used in humid environment was systematically researched in this paper. The influence law of construction time and concrete surface treatment to adhesion and adhesion of coating systems to the adhesion of composite protective coatings in simulative marine environment were also analyzed. The results showed that bonding strength of four primers A,B,C,D with concrete in dry environment is 3.83,3.96,3.57,4.41 MPa respectively. The adhesions property decreased to varying degrees because of humidity,and increased as increased roughness and drying time. As closed systems coatings used in humid environment,the polyurethane-based prepolymer A and two components of waterborne polyurethane primers C were more suitable for concrete used in marine environment as the adhesive strength was 3.57 MPa and 3.82 MPa respectively.
