Suspension bridge cable system anti-corrosion structure based on oxidative polymerization coating technology and construction method of suspension bridge cable system anti-corrosion structure
The invention discloses a suspension bridge cable system anti-corrosion structure based on an oxidative polymerization coating technology and a construction method of the suspension bridge cable system anti-corrosion structure. The anti-corrosion structure of the suspension bridge cable system based on the oxidative polymerization coating technology comprises an anti-corrosion system, and the anti-corrosion system comprises an anti-corrosion paste layer, an anti-corrosion belt layer and an outer protective agent layer. The anti-corrosion paste for forming the anti-corrosion paste layer is prepared from the following raw materials in parts by mass: 50 to 53 parts of polybutylene, 8 to 10 parts of organic bentonite, 5 to 8 parts of rust fixing agent, 0.7 to 1 part of titanium dioxide, 0.5 to 0.7 part of graphite, 20 to 23 parts of talcum powder and 0.1 to 0.2 part of antioxidant; an anti-corrosion belt used for forming the anti-corrosion belt layer is formed by immersing polyester non-woven fabric into filling oil containing anti-corrosion paste components. And an outer protective agent used for forming the outer protective agent layer is a sprayed polyaspartic urea material. According to the anti-corrosion structure of the suspension bridge cable system, the surface of steel can be filled with the anti-corrosion paste, a compact oxidation film is formed, and a corrosive medium can be isolated; the anti-corrosion belt has good following performance and can be well combined with the anti-corrosion paste and attached to the surface of the steel. The polyaspartic polyurea material has excellent waterproofness and weather resistance, can form a compact, continuous and uniform protective layer on the outermost layer of the anti-corrosion belt after being sprayed, and can completely block the invasion of corrosive media in the external environment, thereby achieving the purpose of prolonging the anti-corrosion performance of the cable system of the suspension bridge.
