Carbene environment-friendly descaling derusting anticorrosion antirust liquid and preparation method and application thereof

The invention discloses a carbene environment-friendly descaling derusting anticorrosion antirust liquid and a preparation method and application thereof. The carbene environment-friendly descaling derusting anticorrosion antirust liquid is made from, by mass, 1-10% of carbene, 0.1-1.0% of an accelerant, 0.01-1.00% of a dispersant, and the balance of deionized water. Carbene is water-soluble carbene sol, having pH of 0.5-3, electromotive force E of 280-380 mv, particle size phi of 0.3-20 nm, particle size distribution psi of D90-D98, and solute content of 0.1-1%. The carbene environment-friendly descaling derusting anticorrosion antirust liquid has an efficient quick penetration function and a corrosion inhibition function, allows water scale and rust on the metal wall to be washed and removed within a short time, can protect the base metal and impart a corrosion-inhibiting film coating to the base metal, can provide improved corrosion resistance for a material, and is convenient to use. 本发明公开了种碳烯环保型除垢除锈防腐防锈液
