The invention relates to a coating for corrosion prevention of a metal surface, in particular to an anticorrosive coating containing flame-retardant functionalized carbon nanotubes. The flame-retardant waterborne epoxy resin coating comprises the following components in parts by mass: 100-120 parts of waterborne epoxy resin, 10-20 parts of flame-retardant functionalized carbon nanotubes, 5-10 parts of a flame-retardant aid, 35-45 parts of a curing agent and 10-15 parts of water. The thermal/mechanical property of the composite material can be improved, the brittleness defect in the coating use process is reduced, the metal surface protection capacity is improved, and the flame retardant capacity is improved. 本发明涉及一种用于金属表面防腐的涂料，具体是一种含阻燃功能化碳纳米管的防腐涂料。其包括以下质量份数的组份：水性环氧树脂100~120份、阻燃功能化碳纳米管10~20份、阻燃助剂5~10份、固化剂35~45份、水10~15份。本发明能够改善复合材料的热/力学特性，降低涂料使用中的脆性缺陷，提高金属表面防护能力，提高阻燃能力。
