Corrosion-resistant waterproof polyurethane coating material

The invention discloses a corrosion-resistant and waterproof polyurethane coating material, and belongs to the technical field of coating materials. According to the invention, dodecafluoroheptyl methacrylate, hydroxyl-terminated polybutadiene, nano calcium carbonate, silicone oil, toluene diisocynate and other raw materials are additionally introduced, so that the comprehensive performance of the polyurethane coating material is improved. Through analysis, dodecafluoroheptyl methacrylate possibly participates in the constraint of Van der Waals force among molecules in the coating material, and meanwhile, dodecafluoroheptyl methacrylate and hydroxyl-terminated polybutadiene act together to improve the crosslinking density, so that the contact angle is increased, and the corrosion phenomenon can be reduced by using toluene diisocynate. 本发明公开了一种耐腐防水的聚氨酯涂层材料，属于涂层材料技术领域。本申请额外引入甲基丙烯酸十二氟庚酯、端羟基聚丁二烯、纳米碳酸钙、硅油、甲苯二异氰酸酯等原料，对于聚氨酯涂层材料起到综合性能提升作用。经分析，可能甲基丙烯酸十二氟庚酯参与了涂层材料内部分子间范德华力的约束，同时与端羟基聚丁二烯共同作用提升交联密度，进而使得接触角增大，且甲苯二异氰酸酯的使用可
