| 摘 要： | Six anticorrosion primers were prepared respectively by using two fire retarders-APP and DBDPO. Properties of these primers were determined with four test methods-salt water immersion,salt water spray test,determination of impedance of coated steel and C. R. M. Results show that APP with definite water-soluble property reduced anticorrosion performance of the primers,while non water-soluble DBDPO would not affect the anticorrosion properties of the primers if the Pigment Volume Concentrations(P. V. C)were well calculated.
