In this investigation, the mixed γ‐GPS/BTSE silane solution for preparing well adhered composite γ‐GPS/BTSE silane film on Q235 carbon steel surface has been successfully optimized by orthogonal test, and the curing process parameters of temperature and time have also been optimized. The results indicate that the optimized hydrolysis parameters for mixed silanes agent solution are as follows: V ethanol / V water 3 : 1, V γ‐GPS / V BTSE 2 : 3, V silanes 6 vol.%, pH 4.0 and hydrolysis time 72 h. In addition, the optimized curing condition for composite γ‐GPS/BTSE silane film is 120 °C and 30 min. After immersion in the optimized mixed γ‐GPS/BTSE silanes agent solution and curing under the optimized condition, the prepared composite γ‐GPS/BTSE silane film on Q235 steel surface can have an adhesion strength of 24.52 MPa to underlying steel substrate.
