Abstract

The invention provides a conductive anticorrosive coating using organic silver as a light curing accelerator, belongs to the field of anticorrosive conductive coatings and relates to extraction of aqueous phase Ag+ into an organic phase to be as a photothermal curing agent for organic resins by using N-p-toluenesulfonylpyridine so as to be used for carbon-based anticorrosive coatings, increasingphotocuring effect, promoting film densification and increasing conductivity. Specifically, after the conductive anticorrosive coatings prepared by adding an organic solution of the N-p-toluenesulfonylpyridine is coated on the metal member, a formed film layer is under the photothermal effect of sunlight and consequently, curing speed is accelerately and densification process of the film is promoted; silver complex organic matter can reduce silver ions under photothermal conditions and generate nano silver particles in situ, and silver colloid in a conductive chain can improve conductivity. When the conductive anticorrosive coating is applied to a metal part, the cured anticorrosive coating has the advantages of having excellent weather resistance, oil resistance, salt spray resistance, and acid, alkali, water and other corrosive substance resistance, good conductivity and permeability resistance, and displaying excellent ground net composite anti-corrosion grounding performance.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to conductive anticorrosion coatings. Background technique [0002] As a structural material, metal has excellent strength and electrical conductivity, but iron-based metals cannot meet the corrosion resistance performance. In order to prevent these problems, it is common to form a coating with a corrosion-resistant layer on the metal, and a corrosion-resistant paint is one such material. [0003] For the components of the grounding grid, corrosion will lead to poor grounding performance and poor thermal stability. When the system is struck by lightning or a short-circuit accident occurs, the instantaneous high current may cause the grounding grid to burn out, thereby causing equipment damage and even endangering Personal safety. Therefore, effective anti-corrosion measures must be taken for the grounding grid to ensure that the grounding grid can operate well within the design s...
