Description

technical field [0001] The invention belongs to the field of water-based coatings, in particular to a water-based heavy-duty anti-corrosion and flame-retardant coating for metal substrates and a preparation method thereof. Background technique [0002] Economic and social development has promoted the development of the construction industry. Large-scale buildings such as exhibition halls, terminal buildings, large shopping malls, stadiums, high-end hotels and industrial plants are increasing, and they are developing in a large and beautiful direction. The main load-bearing components Most are metal structures. For this reason, the fire protection of metal structures has attracted more and more attention. Although metal materials are non-combustible materials, their fire resistance is far worse than that of masonry structures and reinforced concrete structures. As the temperature increases, the mechanical strength of metals will decrease. As the temperature rises to the cri...
