Problems solved by technology

[0003] A large number of steel structural parts are used in cable-stayed bridges, which play a role in supporting, fixing and connecting cable-stayed bridges. However, the use of steel structures is prone to corrosion, especially in rivers, rivers, lakes, and sea areas involved in bridges. And choose corrosion-resistant materials, such as weather-resistant steel and stainless steel, but the price is too expensive, so the development of surface treatment technology for steel structural parts is still an important development direction in bridge structures

Abstract

The invention discloses a preparation method of an anticorrosion coating. According to main points of the technical scheme, the method comprises: S1, pouring absolute ethanol to an Erlenmeyer flask, adding tetraethoxysilane, and performing uniform stirring; S2, weighing ammonia water, the mass of which is 0.05-0.1 time of that of tetraethoxysilane, and performing continuous stirring; S3, after thestirring is over, performing heating and drying to obtain nanometer SiO2 particles; S4, performing modification treatment; S5, sealing the container, and performing thermal insulation in a drying oven for 48 h; S6, performing centrifugation and repeated flushing to obtain SiO2, and grinding SiO2; S7, making a spraying suspending liquid; S8, performing spraying; and S9, after spraying is over, performing drying for 4 h, taking the product out, and performing natural cooling. The anticorrosion coating can closely adhere to a substrate, has a good water-isolation effect, and reduces corrosion that appears on the surface.

Description

technical field [0001] The invention relates to the technical field of metal components, in particular to a method for preparing an anti-corrosion coating and its application to metal components of cable-stayed bridges. Background technique [0002] Cable-stayed bridges, also known as cable-stayed bridges, are Main beam A type that is directly pulled on the bridge tower by many cables bridge , is a combination of towers under pressure, cables under tension and beams under bending structural system . It can be regarded as a multi-span elastically supported continuous beam with cables instead of piers. It can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. Cable-stayed bridges are mainly Sota ,Main beam, stay cable composition. [0003] A large number of steel structural parts are used in cable-stayed bridges, which play a role in supporting, fixing and connecting cable-stayed bri...
