Salt-resistant, reinforcing, repairing, corrosion-resistant and anti-seepage coating for seawater cooling tower concrete structure and application thereof
The invention relates to the field of seawater cooling tower repair, and provides a salt-resistant, reinforcing, repairing, corrosion-resistant and anti-seepage coating for a seawater cooling tower concrete structure in order to solve the problem that reinforced concrete of a seawater cooling tower is easily corroded by salt substances such as chloride ions and is difficult to repair. Comprising a matrix salt-resistant agent, a reinforcing steel bar protective coating, integral reinforcing and repairing mortar and a surface layer anti-corrosion and anti-seepage coating. The salt-resistant agent is used for destroying salt substances such as chloride ions, salt substances such as chloride ions remaining in reinforced concrete subjected to physical cleaning are prevented from being continuously corroded, the steel bar protective coating prevents steel bars from being corroded, the mortar is used for repairing and reinforcing concrete, and the concrete grouting liquid is used for bridging and reinforcing cracks existing in a concrete structure. Meanwhile, salt substances such as chloride ions in a concrete matrix can be cured, the surface anti-corrosion and anti-permeability coating ensures that water containing salt, chloride ions and other corrosive media does not permeate into the matrix any more after maintenance, and the concrete structure of the seawater cooling tower is repaired in an all-around mode; and the maintained seawater cooling tower can resist corrosion of corrosive media such as chloride ions and can be safely used for a long time. The invention also provides application of the coating.
本发明涉及海水冷却塔修复领域，针对海水冷却塔的钢筋混凝土易受氯离子等盐类物质腐蚀难修复的问题，提供一种海水冷却塔混凝土结构的抗盐、加固修复和防腐抗渗涂料，包括基体抗盐剂、钢筋保护涂料、整体加固修复砂浆和表层防腐抗渗涂料。本发明用抗盐剂破坏氯离子等盐类物质，防止经物理清理后钢筋混凝土内尚存的氯离子等盐类物质继续腐蚀，钢筋保护涂料防止钢筋受腐蚀，砂浆用于混凝土修复加固，混凝土注浆液用作弥合加固混凝土结构内部存在的裂缝，并同时可固化混凝土基体中氯离子等盐类物质，表面防腐抗渗涂层则确保在维修之后含盐和氯离子等腐蚀介质的水不再往基体中渗入，全方位对海水冷却塔混凝土结构进行修复，使经维修后的海水冷却塔能抵抗氯离子等腐蚀介质的侵蚀，长久安全使用。本发明还提供所述涂料的应用。
