Problems solved by technology

However, since the anti-corrosion paste and anti-corrosion tape are mineral grease products, they will be lost to varying degrees at high temperatures. In addition, as a protection and sealing cover, it is directly in contact with the mineral grease in the anti-corrosion tape during production. The rise causes petrolatum to flow at high temperature, and the channel formed by the flow is difficult to achieve complete sealing in the process of making the protective cover. At the same time, due to the complex construction environment on site, it is difficult to ensure absolute controllability of the quality, so there are different degrees of loss of anti-corrosion components after completion. However, the anti-corrosion performance and weather resistance of the unsaturated polyester resin gel coat used in the system are poor, and the outer surface of the gel coat is easily contaminated with powder ash. and other air pollutants, and the coating is easy to yellow and fall off, which seriously affects the appearance; at the same time, the anti-corrosion system does not have the function of flame retardancy

Description

Technical field [0001] The invention belongs to the technical field of anti-corrosion materials, and specifically relates to a flame-retardant multi-layer coating anti-corrosion system and a construction method thereof. Background technique [0002] Corrosion not only exists in various industrial sectors such as oil exploration, petrochemical and chemical industries, but also exists in many parts of important facilities such as bridges, buildings, offshore equipment, ports, etc. Its destructive power is huge, and it may even affect the facilities in service in severe cases. Normal use threatens the safety of facilities and public safety. Therefore, it is necessary to do a good job in anti-corrosion work and strengthen the management of anti-corrosion to ensure the safety of people's lives. It is essential to formulate necessary and effective measures for the daily operation of production and equipment and facilities. [0003] At present, the more common anti-corrosion materials ma...
