Abstract

The invention discloses a high-voltage transmission lead anti-corrosion paint prepared from modified nano-silicon dioxide and a preparation method of the anti-corrosion paint. The anti-corrosion paintcomprises, by weight, 80-90 parts of acrylic resin, 30-40 parts of styrene-acrylic emulsion, 25-30 parts of modified nano-silicon dioxide, 6-10 parts of graphene, 2-4 parts of sodium hexametaphosphate, 4-6 parts of sodium benzoate, 2-4 parts of carbon fluoride, 6-8 parts of zinc stearate, 2-4 parts of tributyl citrate, 7-9 parts of aluminum zirconate coupling agents, 3-5 parts of hydroxyethyl cellulose, 2-4 parts of polyvinyl alcohol and 100-120 parts of deionized water. Physical performances such as corrosion resistance, dispersity, weather resistance and barrier property of the paint are remarkably improved under synergistic effects of components, nano-silicon dioxide is modified, so that compatibility between the nano-silicon dioxide and an organic macromolecule is improved, rheological properties of a system are improved, and super-hydrophobicity and mechanical wear resistance of the paint are improved.

Description

technical field [0001] The technical field of paint processing of the present invention particularly relates to an anti-corrosion paint prepared by using modified nano-silica for high-voltage transmission wires and a preparation method thereof. Background technique [0002] In power transmission and transformation projects, the phenomenon of icing on wires is common. Faults caused by icing on transmission lines seriously affect the normal operation of the power system. Icing can cause galloping of wires, tilting of towers, collapse, disconnection and flashover of insulators. As a result, major accidents have been caused. At present, the effective measures to prevent insulators from icing are very limited, mainly by changing the suspension mode of the insulator or the structure of the insulator itself. The cost is high and the effect is not good, and the structure of the insulator is affected by the use of the environment. There is not much room for structural changes; The cu...

[0002] In power transmission and transformation projects, the phenomenon of icing on wires is common. Faults caused by icing on transmission lines seriously affect the normal operation of the power system. Icing can cause galloping of wires, tilting of towers, collapse, disconnection and flashover of insulators. As a result, major accidents have been caused. At present, the effective measures to prevent insulators from icing are very limited, mainly by changing the suspension mode of the insulator or the structure of the insulator itself. The cost is high and the effect is not good, and the structure of the insulator is affected by the use of the environment. There is not much room for structural changes; The current RTV coatings have poor hydrophobicity and cannot solve the occurrence of adverse phenomena such as freezing caused by poor flow of water and mist. If a coating with good hydrophobicity is used, the surface dry time, volume resistivity, and dielectric strength may not meet the requirements
