摘　　要：磷酸钾镁水泥(Magnesium Potassium Phosphate Cement,MKPC)作为一种新型无机胶凝材料,具有凝结速度快、早期强度高、结构致密、耐磨性能好等特点。以磷酸钾镁水泥为黏结剂,通过添加剂、矿物掺合料及复合改性等方法对其进行改性,可制备出具有优异防腐性能的金属防护涂层,其主要用于钢材表面的防腐蚀保护。本文总结了磷酸钾镁水泥基涂层的水化与防腐机理,及其材料组分和配合比对涂层防腐性能的影响,重点概述了磷酸钾镁水泥基防腐涂层的改性研究,介绍了该类涂层的施工工艺与性能评价方法,并对磷酸钾镁水泥基涂层在防腐领域中的发展前景进行了展望。Magnesium potassium phosphate cement(MKPC),as a new type of inorganic cementitious material,shows the characteristics of fast setting speed,high early strength,dense structure,and good wear resistance.Employing magnesium potassium phosphate as a binder,modified by additives,mineral admixtures and composite modification methods,metal protective coatings with excellent anti-corrosion properties can be obtained,which are mainly used for corrosion protection of steel surfaces.This paper reviewed the hydration and anti-corrosion mecha-nisms of MKPC-based coatings,examining the influence of material composition and mix design on their protective performance.In particular,the modification approaches for MKPC-based anti-corrosive coatings were discussed,with their application techniques and performance evalua-tion methods being comprehensively documented.Furthermore,prospective applications of MKPC-based coatings in corrosion protection were critically evaluated.
