摘要（英）：

The invention belongs to the technical field of mechanical engineering materials, and provides a water-based antirust paint for the surface of a steel structure, and a coating method thereof. The antirust paint is prepared from the following components in parts by weight: 22-27 parts of water-soluble phenolic resin, 15-20 parts of polyurethane-polyacrylate compound emulsion, 18-22 parts of attapulgite, 7-9 parts of sodium carbonate, 1.0-1.5 parts of triethanolamine, 18-22 parts of polycaprolactone, 0.1-0.3 part of polybutylene terephthalate, 0.7-0.9 part of potassium chloride, 0.4-0.6 part of 2,6-ditert-butyl-alpha-dimethylamino-p-phenol, 1.5-2.5 parts of modified acrylic acid emulsion, 0.5-0.8 part of chitosan, 3-6 parts of cottonseed oil, 5-8 parts of benzyl cinnamate and 8-10 parts of modified auxiliary. The water-based antirust paint for the surface of a steel structure is good in adhesive force, quick in drying, good in heat resistance, environment-friendly and free from pollution, the performance of polymer materials in raw materials can be improved since attapulgite and modified auxiliary are added into the raw materials and are modified, and the corrosion resistance and heat resistance are improved. The coating method is simple, is low cost, and is suitable for large-scale production.
