Anti-corrosion coating technique for reinforced concrete civil defense door

Disclosed is an anti-corrosion coating technique for a reinforced concrete civil defense door. The anti-corrosion coating technique comprises the coating steps that the reinforced concrete civil defense door is rammed preliminarily; the surface of a steel member is cleaned and painted with red lead primer; the surface of reinforced concrete is polished through a diamond hydrostone-flat grinder; the reinforced concrete civil defense door is hardened; the humidity is measured, and drying is conducted; and the surface of the reinforced concrete is coated with epoxy sealing primer, and the surfaceof the steel member and the surface of the reinforced concrete are painted with crylic acid outer wall elastic finishing coat. According to the anti-corrosion coating technique, the cost is saved, the construction progress is accelerated, the working efficiency and the anti-corrosion capability are improved, and the anti-corrosion maintenance period is prolonged. 种钢筋混凝土人防门的防腐涂装工艺，涂装步骤包括：初步捣制钢筋混凝土人防门、清理钢构件的表面并涂刷红丹底漆、使用金刚水
